“We wouldn’t of made friends if we didn’t come to Football United”: the impacts of a football program on young people’s peer, prosocial and cross-cultural relationships

PubMed Central

Background Sport as a mechanism to build relationships across cultural boundaries and to build positive interactions among young people has often been promoted in the literature. However, robust evaluation of sport-for-development program impacts is limited. This study reports on an impact evaluation of a sport-for-development program in Australia, Football United®. Methods A quasi-experimental mixed methods design was employed using treatment partitioning (different groups compared had different levels of exposure to Football United). A survey was undertaken with 142 young people (average age of 14.7 years with 22.5% of the sample comprising girls) in four Australian schools. These schools included two Football United and two Comparison schools where Football United was not operating. The survey instrument was composed of previously validated measures, including emotional symptoms, peer problems and relationships, prosocial behaviour, other-group orientation, feelings of social inclusion and belonging and resilience. Face to face interviews were undertaken with a purposeful sample (n = 79) of those who completed the survey. The participants in the interviews were selected to provide a diversity of age, gender and cultural backgrounds. Results Young people who participated in Football United showed significantly higher levels of other-group orientation than a Comparison Group (who did not participate in the program). The Football United boys had significantly lower scores on the peer problem scale and significantly higher scores on the prosocial scale than boys in the Comparison Group. Treatment partitioning analyses showed positive, linear associations between other-group orientation and total participation in the Football United program. A lower score on peer problems and higher scores on prosocial behaviour in the survey were associated with regularity of attendance at Football United. These quantitative results are supported by qualitative data analysed

Expertise has been extensively studied in several sports over recent years. The specificities of how excellence is achieved in Association Football, a sport practiced worldwide, are being repeatedly investigated by many researchers through a variety of approaches and scientific disciplines. The aim of this review was to identify and synthesise the most significant literature addressing talent identification and development in football. We identified the most frequently researched topics and characterised their methodologies. A systematic review of Web of Science™ Core Collection and Scopus databases was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The following keywords were used: "football" and "soccer". Each word was associated with the terms "talent", "expert*", "elite", "elite athlete", "identification", "career transition" or "career progression". The selection was for the original articles in English containing relevant data about talent development/identification on male footballers. The search returned 2944 records. After screening against set criteria, a total of 70 manuscripts were fully reviewed. The quality of the evidence reviewed was generally excellent. The most common topics of analysis were (1) task constraints: (a) specificity and volume of practice; (2) performers' constraints: (a) psychological factors; (b) technical and tactical skills; (c) anthropometric and physiological factors; (3) environmental constraints: (a) relative age effect; (b) socio-cultural influences; and (4) multidimensional analysis. Results indicate that the most successful players present technical, tactical, anthropometric, physiological and psychological advantages that change non-linearly with age, maturational status and playing positions. These findings should be carefully considered by those involved in the identification and development of football players. This review highlights the need for coaches

Research on the epidemiology of football injuries in Africa is very sparse despite its importance for injury prevention planning in a continent with limited sports medicine resources. The vast majority of studies available in literature were conducted in Europe and only a very few studies have prospectively reported the pattern of football injury in Africa. The purpose of this study was to evaluate the incidence and pattern of injuries in a cohort of male and female semi-professional football players in Nigeria. A prospective cohort design was conducted, in which a total of 756 players with an age range of 18-32 years (356 males and 300 females) from 22 different teams (12 male and 10 female teams), were prospectively followed in a National Football Tournament. Physiotherapists recorded team exposure and injuries. Injuries were documented using the consensus protocol for data collection in studies relating to football injury surveillance. An overall incidence of 113.4 injuries/1000 h (95% CI 93.7-136.0) equivalent to 3.7 injuries/match and time-loss incidence of 15.6 injuries/1000 h were recorded for male players and 65.9 injuries/1000 h (95% CI 48.9-86.8) equivalent to 2.2 injuries/match and time-loss incidence of 7.9 injuries/1000 h were recorded for female players. Male players had a significantly higher risk of injuries [IRR = 1.72 (95% CI 1.23-2.45)]. Injuries mostly affected the lower extremity for both genders (n = 81, 70% and n = 31, 62% for males and females respectively). Lower leg contusion (n = 22, 19%) and knee sprain (n = 9, 18%) were the most common specific injury types for male and female players respectively. Most of the injuries were as a result of contact with another player (n = 102, 88%-males; n = 48, 96%-females). Time-loss injuries were mostly estimated as minimal (n = 11, 69%) for male players and severe (n = 4, 66%) for female players.

Following recent research evidencing that young men are redefining the essential components of what it is to be a man, this paper draws on qualitative interviews with 22 elite-level, English Premier League academy level football (soccer) players to investigate their performances and understandings of masculinity in relation to decreasing homohysteria. Even in this gender-segregated, near-total institution, these working-class, non-educationally aspiring adolescents evidence an attenuated performance of 'maleness' and improved attitudinal disposition toward homosexuality. Congruent with insights developed by inclusive masculinity scholars, respondents maintained emotional closeness and physical tactility with male teammates and friends. These more inclusive attitudes and homosocial behaviours were, however, slightly more conservative than in other recent research. We close by explaining this variation with reference to theoretical apparatus' provided by Goffman and Bourdieu to advance theoretical debates about social class and masculinities. © London School of Economics and Political Science 2016.

The purpose of genital examination (GE) during the Pre-participation Physical Examination (PPE) is to identify the state of maturity, and rule out any genital pathology. To describe genital anomalies (GA) and estimate the awareness of GE in young football players. A descriptive, cross-sectional study was conducted in 280 elite football players from the results of PPE over two seasons. There was a detection rate of 5.4% GA, with varicocele being 3.2%, and of which only 13% were aware of their condition. Although this study shows a low incidence of genital abnormality in the study population, only 13% were aware of the GE prior to assessment. These findings demonstrate a low incidence of GA in this population. While GE is recommended during PPE, it is not a routine practice performed by family doctors or sports medicine specialists. This article attempts to raise awareness of the importance of GE in PPE as a preventive health strategy. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier Espana.

This study aimed to realize a prospective follow-up of the injuries occurring in female and male football players involved in the highest league in the Grand-Duchy of Luxembourg. Data concerning anthropometric characteristics and football activities were gathered in 125 female and 243 male football players via questionnaires at the beginning of the study. Then, a follow-up of moderate to severe injuries (> 15 days of interruption in football practice) was performed throughout the season 2013-2014. Sixteen injuries (injury incidence = 0.7 injuries/1000 h of exposure) were observed in 13 female football players (10.4%). These injuries concerned mainly the knee (n = 7; 43.7%), with capsules and ligaments being the most often concerned tissues (n = 7; 43.7%). In male football players, 41 severe injuries (injury incidence = 0.6 injuries/1000 h of exposure) were observed in 36 players (14.8%). These injuries concerned mainly the thighs (n = 12; 29.3%) and the muscles and tendons were the most often concerned tissues (n = 18; 43.9%). Injuries in football are predominantly located at the lower limbs, particularly the knees in female football players. The predominant muscle and tendon lesions of the thighs occurring in males could reveal that physical preparation is insufficient or inadequate for a number of players. Regarding these results, it is necessary to implement an injury prevention strategy. The "FIFA 11+" programme could be used as the basic method, but should be personalized according to sex. The injury collection methodology could be optimized with the use of an electronic database, such as the Training and Injury Prevention Platform for Sports (TIPPS). Beside the systematic recording of injury data (as well as the training load) by the players or the medical staff, this system allows to share of important information between stakeholders, follow-up the players, provide risk factor warnings and increase the awareness of the injury problem.

The aim of this work was to investigate the metabolic and muscle damage responses after the level-1 Yo-Yo intermittent recovery test (YYIRT) in young football players. Fifteen male football players (17.42 ± 0.2 yrs, 69.91 ± 4.4 kg, 178.64 ± 3.8 cm; mean ± SD) participated in this study. Fasting blood samples for various biochemical parameters (i.e. lactate (Lac), glucose (GLC), triglycerides (Tri), creatine kinase (CK), uric acid (UA)) collected from a forearm vein after 5-min of seated rest and 3-min after the test. Moreover, rating of perceived exertion (RPE) and maximal heart rate during and after the YYIRT were recorded. Mean levels of the selected biochemical markers were raised after the YYIRT exercise (P<0.001 for the other markers). Moreover, lipid parameters increased significantly after the test (P<0.01 for Tri and P<0.001 for HDL). These findings confirm the higher metabolic demand of aerobic as well as anaerobic metabolism and reflect a significant mobilization of purine cycle during the YYIRT. The increase of muscle damage markers also reflects the higher anaerobic solicitation. From these findings, we can conclude the importance of aerobic and anaerobic metabolism during soccer-specific endurance performance (i.e. YYIRT, soccer match).

We investigated the musculoskeletal health profile of elite female football players (ET) in comparison to untrained (UT) young women subjected to 16 weeks of football training (2 × 1 h per week). DXA scans, blood sampling, sprint testing and Flamingo postural balance testing were carried out for 27 Danish national team players and 28 untrained women, with eight women being tested after training. At baseline total BMD and BMC were 13% (1.305 ± 0.050 versus 1.159 ± 0.056 g · cm(-2)) and 23% (3047 ± 235 versus 2477 ± 526 g) higher (P <0.001) and leg BMD and BMC were 24 and 28% higher (P <0.01) in ET than in UT. Resting plasma osteocalcin was 45% higher in ET than in UT (28.8 ± 10.9 versus 19.9 ± 9.9 µg · L(-1), P <0.05). Total lean body mass was 14% higher (50.4 ± 3.3 versus 44.3 ± 4.0 kg) in ET compared with UT, with no difference in total body mass. The number of Flamingo test falls was 56-63% less (P <0.01) and 30 m sprinting speed was 31% faster (P <0.001) in ET than UT. After 16 weeks of football training for UT, lean body mass increased by 1.4 ± 0.5 kg and the number of left leg falls decreased by 29% (P <0.05). No significant changes occurred in BMD or BMC, but plasma osteocalcin increased (P <0.05) by 37%. In summary, elite women footballers have an impressive musculoskeletal health profile compared with untrained controls, but short-term football training seems to reduce the risk of falls and increase bone formation.

There is a paucity of evidence regarding the use of injury prevention programmes for preadolescents participating in sport. “The 11 ”injury prevention programme was developed by FIFA’s medical research centre (F-MARC) to help reduce the risk of injury in football players aged 14 years and over. The aim of this study was to determine the suitability and effectiveness of “The 11 ”for younger football players. Twenty-four [12 experimental (EXP), 12 control (CON)] young football players (age 10.4 ± 1.4 yr) participated. The EXP group followed “The 11 ”training programme 5 days per week, for 6 weeks, completing all but one of the 10 exercises. Prior to, and after the intervention, both EXP and CON groups performed a battery of football-specific physical tests. Changes in performance scores within each group were compared using independent t-tests (p ≤ 0.05). Feedback was also gathered on the young players’ perceptions of “The 11”. No injuries occurred during the study in either group. Compliance to the intervention was 72%. Measures of leg power (3 step jump and counter-movement jump) increased significantly (3.4 and 6.0% respectively, p < 0.05). Speed over 20 m improved by 2% (p < 0.05). Most players considered “The 11 ”beneficial but not enjoyable in the prescribed format. Given the observed improvements in the physical abilities and the perceived benefits of “The 11”, it would appear that a modified version of the programme is appropriate and should be included in the training of young football players, for both physical development and potential injury prevention purposes, as well as to promote fair play. To further engage young football players in such a programme, some modification to “The 11 ”should be considered. Key pointsChildren who participate in recreational and competitive sports, especially football, are susceptible to injury.There is a need for the design and assessment of injury prevention programmes for children

Physiological Responses During Multiplay Exergaming in Young Adult Males are Game-Dependent

Regular moderate-intensity exercise provides health benefits. The aim of this study was to examine whether the selected exercise intensity and physiological responses during exergaming in a single and multiplayer mode in the same physical space were game-dependent. Ten males (mean ±SD, age: 23 ±5 years, body mass: 84.2 ±15.6 kg, body height: 180 ±7 cm, body mass index: 26.0 ±4.0 kg·m−2) played the games Kinect football, boxing and track & field (3 × ∼10 min, ∼ 2 min rest periods) in similar time sequence in two sessions. Physiological responses were measured with the portable Cosmed K4b2 pulmonary gas exchange system. Single play demands were used to match with a competitive opponent in a multiplay mode. A within-subjects crossover design was used with one-way ANOVA and a post-hoc t-test for analysis (p<0.05). Minute ventilation, oxygen uptake and the heart rate were at least 18% higher during a multiplayer mode for Kinect football and boxing but not for track & field. Energy expenditure was 21% higher during multiplay football. Single play track & field had higher metabolic equivalent than single play football (5.7 ±1.6, range: 3.2–8.6 vs 4.1 ±1.0, range: 3.0–6.1, p<0.05). Exergaming in a multiplayer mode can provide higher physiological demands but the effects are game-dependent. It seems that exergaming with low intensity in a multiplayer mode may provide a greater physical challenge for participants than in a single play mode but may not consistently provide sufficient intensity to acquire health benefits when played regularly as part of a programme to promote and maintain health in young adults.

Tackling in Youth Football.

PubMed

2015-11-01

American football remains one of the most popular sports for young athletes. The injuries sustained during football, especially those to the head and neck, have been a topic of intense interest recently in both the public media and medical literature. The recognition of these injuries and the potential for long-term sequelae have led some physicians to call for a reduction in the number of contact practices, a postponement of tackling until a certain age, and even a ban on high school football. This statement reviews the literature regarding injuries in football, particularly those of the head and neck, the relationship between tackling and football-related injuries, and the potential effects of limiting or delaying tackling on injury risk.

Programs aimed at preventing violence against women have increasingly adopted bystander approaches, yet large gaps remain in our knowledge about what drives bystanders to act or not, particularly in settings where there is an increased risk of violence against women occurring. This article contributes to this gap by examining data from research with professional male athletes from the Australian Football League. Drawing from a mixed methods approach, including a survey and interviews with football players, we outline some of the challenges to bystander intervention faced by professional athletes and discuss some of the possible similarities and differences between these and other groups of men. © The Author(s) 2015.

Gradidge, Philippe Jean-Luc; Constantinou, Demitri

The aim of this comparative study was to determine the gender differences in cardiac morphology and performance in adolescent black South African footballers. Anthropometry, electrocardiography and echocardiography data were measured in 167 (85 males and 82 females) adolescent black South African footballers (mean age: 14.8 ± 1.3 years). Vertical jump height was used as a performance measure of explosive lower-limb power. The males had less body fat compared with the females (12.1 ± 3.6 vs 16.8 ± 4.1%, p < 0.05), while females had higher left ventricular end-diastolic diameters compared with males (48.7 ± 3.7 vs 40.7 ± 8.1, p < 0.05). Vertical jump height was higher in males (37.2 ± 10.3) compared with females (31.2 ± 8) and was inversely associated with body fat (β = -0.2, p < 0.05) and positively associated with lean mass (β = 0.5, p < 0.05). The findings showed that adolescent black South African male footballers had a performance advantage over females for explosive lower-limb power, which was explained by differences in body composition and not cardiac morphology.

The aims of this study were (1) to determine minutes of moderate-to-vigorous physical activity (PA) and vigorous PA accrued in youth sport football (also internationally referred to as soccer), and the contribution toward daily weekend moderate-to-vigorous PA and vigorous PA for males aged 9-16 years, and (2) to investigate variability in these outcomes related to age and playing position. One hundred and nine male grassroots footballers (Mean age = 11.98 ± 1.75 years) wore a GT3× accelerometer for 7 days. Weekend youth sport football participation and playing position were recorded. Youth sport football moderate-to-vigorous PA (M = 51.51 ± 17.99) and vigorous PA (M = 27.78 ± 14.55) contributed 60.27% and 70.68% toward daily weekend moderate-to-vigorous PA and vigorous PA, respectively. Overall, 36.70% of participants accumulated ≥60 min moderate-to-vigorous PA and 69.70% accrued ≥ 20 min of vigorous PA during youth sport. For participants aged 13 to16 years, youth sport football moderate-to-vigorous PA and vigorous PA were significantly higher, and contributed a greater amount toward daily weekend moderate-to-vigorous PA and vigorous PA than for participants aged 9-12 years (p = <.01). Youth sport football is an important source of moderate-to-vigorous PA and vigorous PA at the weekend for male youth, and particularly for adolescents. Participation may offer opportunity for weekend engagement in vigorous PA toward health enhancing levels.

Chronic groin pain is a common problem in association football players. Normative values for the strength of hip muscles, measured in an accurate and accessible manner, are needed to gauge strength and inform return to play decisions in this group. The purpose of this study was to define normative values of hip muscle strength using handheld dynamometry. A series of reliable clinical tests that are commonly used when making return to sport decisions in athletes with chronic adductor related groin pain have been selected. One hundred and twenty adult male association football players, free from injury, were recruited. Isometric strength of the hip flexors and adductor muscles was measured using a handheld dynamometer. Mean age was 24.9 years (SD 5.9). Eighty participants (67%) had experienced groin pain in the past. Mean strength for dominant leg hip flexion was 47.3 kg (95% confidence interval 45.6-49.0), non-dominant leg hip flexion was 42.5 kg (41.1-43.9), adduction at 0 degrees hip flexion was 35.6 kg (34.1-37.1), adduction at 45 degrees was 32.0 kg (30.9-33.1), and adduction at 90 degrees was 25.5 kg (24.4-26.5). This study establishes reference ranges and predictive equations for maximal isometric contraction strength of the hip muscles in non-injured adult male association football players. This information will assist assessment and management of an athlete's return to play following injury. 2009 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

The Motor Subsystem as a Predictor of Success in Young Football Talents: A Person-Oriented Study

Zibung, Marc; Zuber, Claudia; Conzelmann, Achim

2016-01-01

Motor tests play a key role in talent selection in football. However, individual motor tests only focus on specific areas of a player’s complex performance. To evaluate his or her overall performance during a game, the current study takes a holistic perspective and uses a person-oriented approach. In this approach, several factors are viewed together as a system, whose state is analysed longitudinally. Based on this idea, six motor tests were aggregated to form the Motor Function subsystem. 104 young, top-level, male football talents were tested three times (2011, 2012, 2013; Mage, t2011 = 12.26, SD = 0.29), and their overall level of performance was determined one year later (2014). The data were analysed using the LICUR method, a pattern-analytical procedure for person-oriented approaches. At all three measuring points, four patterns could be identified, which remained stable over time. One of the patterns found at the third measuring point identified more subsequently successful players than random selection would. This pattern is characterised by above-average, but not necessarily the best, performance on the tests. Developmental paths along structurally stable patterns that occur more often than predicted by chance indicate that the Motor Function subsystem is a viable means of forecasting in the age range of 12–15 years. Above-average, though not necessary outstanding, performance both on fitness and technical tests appears to be particularly promising. These findings underscore the view that a holistic perspective may be profitable in talent selection. PMID:27508929

Match running performance and skill execution improves with age but not the number of disposals in young Australian footballers.

This study investigated age-related differences in maturity, physical and functional characteristics and playing performance in youth Australian Football (AF). Young male players (n = 156) were recruited from 12 teams across 6 age groups (U10-U15) of a recreational AF club. All players were tested for body size, maturity and fitness. Player performance was assessed during a match in which disposals (kicks and handballs) and their effectiveness were coded from a video recording and match running performance measured using Global Positioning System. Significant main effects (P < 0.01) for age group were observed for age, years to peak height velocity, body mass, height, 20 m sprint, maximal speed over 20 m, vertical jump, 20 m multistage shuttle run, match distance, high-speed running distance, peak speed, number of effective disposals and percentage of effective disposals. Age-related differences in fitness characteristics (speed, lower body power and endurance) appeared to transfer to match running performance. The frequency in which players disposed of the football did not differ between age groups, however the effectiveness of each disposal (i.e., % effective disposals) improved with age. Match statistics, particularly those that evaluate skill execution outcome (i.e., effectiveness), are useful to assess performance and to track player development over time. Differences between age groups, and probably variability within age groups, are strongly associated with chronological age and maturity.

The purpose of this study was twofold: (a) to investigate the prevalence of hip and groin pain in sub-elite male adult football in Denmark and (b) to explore the association between prevalence and duration of hip and groin pain in the previous season with the Copenhagen Hip and Groin Outcome Score (HAGOS) in the beginning of the new season. In total 695 respondents from 40 teams (Division 1-4) were included. Players completed in the beginning of the new season (July-Sept 2011) a self-reported paper questionnaire on hip and/or groin pain during the previous season and HAGOS. In total 49% (95% CI: 45-52%) reported hip and/or groin pain during the previous season. Of these, 31% (95% CI: 26-36%) reported pain for >6 weeks. Players with the longest duration of pain during the previous season had the lowest HAGOS scores, when assessed at the beginning of the new season, P < 0.001. This study documents that half of sub-elite male adult football players report pain in the hip and/or groin during a football season. The football players with the longest duration of pain in previous season displayed the lowest HAGOS scores in the beginning of the new season. © 2015 John Wiley & Sons A/S.

Objective To assess whether high school football played between 1946 and 1956, when headgear was less protective than today, was associated with development of neurodegenerative diseases later in life. Methods All male students who played football from 1946 to 1956 in the high schools of Rochester, Minnesota, plus a non–football-playing referent group of male students in the band, glee club, or choir were identified. Using the records-linkage system of the Rochester Epidemiology Project, we reviewed (from October 31, 2010, to March 30, 2011) all available medical records to assess later development of dementia, Parkinson disease (PD), or amyotrophic lateral sclerosis (ALS). We also compared the frequency of dementia, PD, or ALS with incidence data from the general population of Olmsted County, Minnesota. Results We found no increased risk of dementia, PD, or ALS among the 438 football players compared with the 140 non–football-playing male classmates. Parkinson disease and ALS were slightly less frequent in the football group, whereas dementia was slightly more frequent, but not significantly so. When we compared these results with the expected incidence rates in the general population, only PD was significantly increased; however, this was true for both groups, with a larger risk ratio in the non–football group. Conclusion Our findings suggest that high school students who played American football from 1946 to 1956 did not have an increased risk of later developing dementia, PD, or ALS compared with non–football-playing high school males, despite poorer equipment and less regard for concussions compared with today and no rules prohibiting head-first tackling (spearing).

Background Current knowledge on anterior cruciate ligament (ACL) injury mechanisms in male football players is limited. Aim To describe ACL injury mechanisms in male professional football players using systematic video analysis. Methods We assessed videos from 39 complete ACL tears recorded via prospective professional football injury surveillance between 2001 and 2011. Five analysts independently reviewed all videos to estimate the time of initial foot contact with the ground and the time of ACL tear. We then analysed all videos according to a structured format describing the injury circumstances and lower limb joint biomechanics. Results Twenty-five injuries were non-contact, eight indirect contact and six direct contact injuries. We identified three main categories of non-contact and indirect contact injury situations: (1) pressing (n=11), (2) re-gaining balance after kicking (n=5) and (3) landing after heading (n=5). The fourth main injury situation was direct contact with the injured leg or knee (n=6). Knee valgus was frequently seen in the main categories of non-contact and indirect contact playing situations (n=11), but a dynamic valgus collapse was infrequent (n=3). This was in contrast to the tackling-induced direct contact situations where a knee valgus collapse occurred in all cases (n=3). Conclusions Eighty-five per cent of the ACL injuries in male professional football players resulted from non-contact or indirect contact mechanisms. The most common playing situation leading to injury was pressing followed by kicking and heading. Knee valgus was frequently seen regardless of the playing situation, but a dynamic valgus collapse was rare. PMID:25907183

All football injuries treated at the Emergency Department, Oslo City Hospital, 1329 patients, 1167 males and 162 females, were recorded for one year, accounting for 28.4% of all sports injuries. Most injuries seen were in the 15-19 years age group in females and 20-24 years age group in males; 68% of the females and 42% of the males (p less than 0.001) were below 20 years of age, and 87% of the injuries occurred in competitive football. During matches, 695 players were injured giving an incidence of 34.5 injuries/10,000 player matches. The injuries occurred all year with a peak in June. Sprains accounted for 41% of the injuries, 23% were contusions and 19% fractures. Most injuries (59%) affected the legs. Hospital admission was required for three females and 57 males. The football injuries required 1966 consultations and necessitated that 349 patients had to stay away from work for a total of 6137 days. PMID:6487944

The Muslim football player and Ramadan: current challenges.

Islam is a monotheistic Abrahamic faith characterised by devotional orthopraxy. The actions expected of followers of Islam are closely prescribed in the Qur'an. Muslims understand Ramadan as a mandatory requirement, excused only in the event of illness, infirmity or extremes of age. Due to the increasing popularity of football among Muslims, more and more Muslim football players of all levels make the decision to follow the Ramadan fast while they need to practise and compete. Sports medicine clinicians and scientists have the responsibility to provide them with the knowledge and evidence on how exactly Ramadan fasting impacts on their performance and how to optimise their eating, drinking and sleeping in order to minimise negative effects of their religious practice, should any have been demonstrated. The first International Federation of Football Associations (FIFA) Medical Assessment and Research Centre (F-MARC) study concluded that biochemical, nutritional, subjective well-being and performance variables were not adversely affected in young male national level players who followed Ramadan fasting in a controlled environment. Match performance was however not measured and the study did not include elite level players, leading to the Ramadan consensus meeting in order to answer the remaining questions. The conclusions and recommendations published in this supplement suggest that the best coping strategies will remain individual - as is the choice to fast.

Athletes require sufficient nutrition knowledge and skills to enable appropriate selection and consumption of food and fluids to meet their health, body composition, and performance needs. This article reports the nutrition knowledge and dietary habits of male football (soccer) players in Australia. Players age 18 years and older were recruited from 1 A-League club (professional) and 4 National Premier League clubs (semiprofessional). No significant difference in general nutrition knowledge (GNK; 54.1% ± 13.4%; 56.8% ± 11.7%; M ± SD), t(71) = -0.91, p = .37, or sports nutrition knowledge (SNK; 56.9% ± 15.5%; 61.3% ± 15.9%), t(71) = -1.16, p = .25) were noted between professional (n = 29) and semiprofessional (n = 44) players. In general, players lacked knowledge in regard to food sources and types of fat. Although nutrition knowledge varied widely among players (24.6-82.8% correct responses), those who had recently studied nutrition answered significantly more items correctly than those who reported no recent formal nutrition education (62.6% ± 11.9%; 54.0% ± 11.4%), t(67) = 2.88, p = .005). Analysis of 3-day estimated food diaries revealed both professionals (n = 10) and semiprofessionals (n = 31) consumed on average less carbohydrate (3.5 ± 0.8 gC/kg; 3.9 ± 1.8 gC/kg) per day than football-specific recommendations (FIFA Medical and Assessment Research Centre [F-MARC]: 5-10 gC/kg). There was a moderate, positive correlation between SNK and carbohydrate intake (n = 41, ρ = 0.32, p = .04), indicating that players who exhibited greater SNK had higher carbohydrate intakes. On the basis of these findings, male football players in Australia would benefit from nutrition education targeting carbohydrate and fat in an attempt to improve nutrition knowledge and dietary practices.

To determine if baseline Sport Concussion Assessment Tool, third Edition (SCAT3) scores differ between athletes with and without disability. Cross-sectional comparison of preseason baseline SCAT3 scores for a range of England international footballers. Team doctors and physiotherapists supporting England football teams recorded players' SCAT 3 baseline tests from August 1, 2013 to July 31, 2014. A convenience sample of 249 England footballers, of whom 185 were players without disability (male: 119; female: 66) and 64 were players with disability (male learning disability: 17; male cerebral palsy: 28; male blind: 10; female deaf: 9). Between-group comparisons of median SCAT3 total and section scores were made using nonparametric Mann-Whitney-Wilcoxon ranked-sum test. All footballers with disability scored higher symptom severity scores compared with male players without disability. Male footballers with learning disability demonstrated no significant difference in the total number of symptoms, but recorded significantly lower scores on immediate memory and delayed recall compared with male players without disability. Male blind footballers' scored significantly higher for total concentration and delayed recall, and male footballers with cerebral palsy scored significantly higher on balance testing and immediate memory, when compared with male players without disability. Female footballers with deafness scored significantly higher for total concentration and balance testing than female footballers without disability. This study suggests that significant differences exist between SCAT3 baseline section scores for footballers with and without disability. Concussion consensus guidelines should recognize these differences and produce guidelines that are specific for the growing number of athletes living with disability.

Testosterone and related compounds are the most recurrent doping substances. The steroid profile, consisting of the quantification of testosterone and its metabolites, has been described as the most significant biomarker to detect doping with pseudo-endogenous anabolic steroids. The steroidal module of the Athlete Biological Passport (ABP) was launched by the World Anti-Doping Agency (WADA) in 2014. To assess the value of introducing the module to its anti-doping programme, the Union of European Football Associations (UEFA) decided to analyze retrospectively the steroid profile data of 4195 urine samples, collected from 879 male football players and analyzed in 12 WADA-accredited laboratories between 2008 and mid-2013. This study focused on the evaluation of T/E ratios. The coefficient of variation (CV) and the adaptive model were the two statistical models used to study the longitudinal follow-up. A CV of 46% was determined to be the maximal natural intra-individual variation of the T/E when the sequence consisted of single data points analyzed in different laboratories. The adaptive model showed some profiles with an atypical T/E sequence and also enabled an estimate of the prevalence of external factors impacting the T/E sequences. Despite the limitations of this retrospective study, it clearly showed that the longitudinal and individual follow-up of the T/E biomarker of the players is a good tool for target testing in football. UEFA has therefore decided to implement the steroidal module of the ABP from the start of the next European football season in September 2015. Copyright © 2015 John Wiley & Sons, Ltd.

To assess high school (HS) football players' knowledge of concussions and to determine whether increased knowledge is correlated with better attitudes toward reporting concussion symptoms and abstaining from play. Two survey tools were used to assess athletes' knowledge and attitudes about concussions. Surveys collected information about demographics, knowledge about concussions, and attitudes about playing sports after a concussion. All athletes present completed one of the 2 surveys. A knowledge and attitude score for each survey was calculated. Frequencies and mean values were used to characterize the population; regression analysis, analysis of variance, and t tests were used to look for associations. A football camp for HS athletes in the Cincinnati area. Male HS football players from competitive football programs in the Cincinnati area. None. Scores on knowledge and attitude sections; responses to individual questions. One hundred twenty (100%) athletes were enrolled although not every athlete responded to every question. Thirty (25%) reported history of a concussion; 82 (70%) reported receiving prior concussion education. More than 75% correctly recognized all concussion symptoms that were asked, except "feeling in a fog" [n = 63 (53%)]. One hundred nine (92%) recognized a risk of serious injury if they return to play too quickly. Sixty-four (54%) athletes would report symptoms of a concussion to their coach; 62 (53%) would continue to play with a headache from an injury. There was no association between knowledge score and attitude score (P = 0.08). Despite having knowledge about the symptoms and danger of concussions, many HS football athletes in our sample did not have a positive attitude toward reporting symptoms or abstaining from play after a concussion. Physicians should be aware that young athletes may not report concussion symptoms.

Psychological characteristics are crucial to identifying talents, which is why these are being incorporated in today's multidimensional talent models. In addition to multidimensionality, talent studies are increasingly drawing on holistic theories of development, leading to the use of person-oriented approaches. The present study adopts such an approach by looking at the influence that motivational characteristics have on the development of performance, in a person-oriented way. For this purpose, it looks at how the constructs achievement motive, achievement goal orientation and self-determination interact with one another, what patterns they form and how these patterns are linked to subsequent sports success. Ninety-seven top young football players were questioned twice. Another year later, it was enquired which of these players had been selected for the U15 national team. At both measuring points, four patterns were identified, which displayed a high degree of structural and individual stability. As expected, the highly intrinsically achievement-oriented players were significantly more likely to move up into the U15 national team. The results point to the importance of favourable patterns of motivational variables in the form of specific types, for medium-term performance development among promising football talents, and thus provide valuable clues for the selection and promotion of those.

The aim of this paper is to study the prevalence of Raynaud's phenomenon in young males. Young males were examined prospectively in a district hospital, and laboratory tests were performed on the basis of the clinical history. Young males (3.912), age 18-28 years old, were examined. Raynaud's phenomenon was present in seven men (1,79 per 1.000, 95% CI 0.72-3.68). Three of them had at least one member in their family diagnosed with Raynaud's phenomenon. Three were smokers. All had negative immunological test. Five patients reported having severe attacks and two had only mild ischemic attacks. The treatment was conservative for all patients, two of them necessitated vasodilators. Very low prevalence of Raynaud's phenomenon was observed in this young male group compared with the previous studies.

Football is one of the most popular sports in the United States and is the leading cause of sports-related injury. A large focus in recent years has been on concussions, sudden cardiac death, and heat illness, all thought to be largely preventable health issues in the young athlete. Injury prevention through better understanding of injury mechanisms, education, proper equipment, and practice techniques and preseason screening may aid in reducing the number of injuries. Proper management of on-field injuries and health emergencies can reduce the morbidity associated with these injuries and may lead to faster return to play and reduced risk of future injury. This article reviews current concepts surrounding frequently seen football-related injuries.

Evidence is accumulating that exercise-based rehabilitation improves physical capacity and quality of life in cancer survivors. However, recruitment and persistence of male cancer patients in rehabilitation and physical activity are low and novel health promotion strategies are warranted. The purpose of this study was to gain an understanding of the meaning of recreational football as a team and interaction-oriented health-promoting activity in men with prostate cancer (n = 26). Qualitative data were collected through six focus group interviews (n = 4-6) and 20 h of participant observations. The two data sets were analyzed using framework analysis. The analysis produced 11 subthemes that were structured into three overarching themes: (a) motivational drivers; (b) united in sport; and (c) confirmation of own capacity. The findings indicated that participants regarded football as a welcome opportunity to regain control and acquire a sense of responsibility for own health without assuming the patient role, and football training legitimized and promoted mutual caring behavior in a male-oriented context. In conclusion, the study suggests that football, due to its cultural representation of masculine ideals, may be a potent and unique strategy for increasing recruitment and adherence to physical activity in prostate cancer patients. © 2014 John Wiley & Sons A/S.

The high injury incidence during match-play in female adolescent football is a major concern. In football, males and females play matches with the same football size. No studies have investigated the effect of football size on injury incidence in female adolescent football. Thus, the aim of the present study was to investigate the effects of introducing a lighter, smaller football on the injury pattern in female adolescent football. We conducted a pilot cluster randomized controlled trial including 26 football teams representing 346 adolescent female football players (age 15-18 years). The teams were randomized to a new lighter, smaller football (INT, N.=12 teams) or a traditional FIFA size 5 football (CON, N.=14 teams) during a full match-season. Acute time-loss injuries and football-exposure during match-play were reported weekly by text-message questions and verified subsequently by telephone interview. In total, 46 acute time-loss injuries were registered (5 severe injuries), yielding an incidence rate of 15.2 injuries per 1000 hours of match-play (95% CI: 8.5-27.2) in INT and 18.6 injuries per 1000 hours of match-play (95% CI: 14.0-24.8) in CON. The estimated 22% greater injury incidence rate risk (IRR: 1.22 [95% CI: 0.64-2.35]) in the CON group was not significant. With an IRR of 1.22, a future RCT main study would need to observe 793 acute time-loss injuries during match-play, in order to have a power of 80%. A large-scaled RCT is required to definitively test for beneficial or harmful effects of a lighter, smaller football in adolescent female football.

The aim of the study was to determine the effect of football school program and physical education curriculum on changes in the motor abilities of 7- and 8-year-old boys. The study included a sample of 180 boys divided into group 1 (7-year-old boys), subdivided to experimental (n = 40) and control (n = 50) groups, and group 2 (8-year-old boys), subdivided to experimental (n = 40) and control (n = 50) groups. Experimental groups included children attending three training units of football training over a 9-month period, in addition to the conventional physical education curriculum. Control groups included children attending only conventional physical education curriculum. All study subjects underwent testing with a battery of 12 motor tests at the beginning and at the end of the study. Results obtained by discriminative canonic analysis showed no statistically significant between-group difference in motor abilities at the beginning of the study. However, significant differences in favor of experimental groups were recorded at the end of the study. Favorable changes in all motor variables were observed in both experimental and control groups of children from the initial through the final state. These changes were more pronounced in experimental groups. Analysis of variance for difference variables (final to initial measurement) indicated programmed education in the form of football training in addition to regular physical education curriculum to predominantly influence the development of aerobic endurance, agility, speed and flexibility in 7-year-old boys, and of explosive strength, aerobic endurance, flexibility and speed in 8-year-old boys. In the latter, football training led to the formation of a motor complex integrating explosiveness, speed, coordination, endurance and flexibility as a general motor factor determining future quality development in football.

Abstract The study examined the effect of caffeine supplementation on match activities and development of fatigue during a football match. In a randomised, double-blind cross-over design, two experimental football games separated by 7 days were organised between the junior teams of two professional football clubs (17.6 ± 1.1 years (±s), 71.7 ± 6.9 kg, 13.9% ± 5.0% body fat). The players ingested either a capsule of 6 mg · kg -1  b.w. caffeine or placebo (dextrose) 65 min prior to the matches. Match activities were assessed using the ZXY match analysis system, and a Yo-Yo intermittent recovery test-level 2 (Yo-Yo IR2) was conducted immediately post-game. Heart rate was monitored throughout the game, and blood samples were obtained at baseline, half-time and after the game. There were no differences between caffeine and placebo regarding total distance covered (10,062 ± 916 vs 9854 ± 901 m), high-intensity running (557 ± 178 vs 642 ± 240 m), sprinting distance (109 ± 58 vs 112 ± 69 m) or acceleration counts (123 ± 31 vs 126 ± 24). In both trials, players displayed lower (P < 0.05) values in total distance and acceleration counts in the last 15 min compared to all other 15-min periods of the matches. Post-game Yo-Yo IR2 performance was not different between game trials (caffeine: 829 ± 322 m; placebo 819 ± 289 m). In conclusion, oral caffeine administration does not appear to have an ergogenic effect in young football players during match play.

The aim was to compare the epidemiology of injuries between elite male and female football players from the same club. Injuries and individual exposure time in a male team and a female team, both playing in the Spanish first division, were prospectively recorded by the club's medical staff for five seasons (2010-2015) following the FIFA consensus statement. Total, training, and match exposure hours per player-season were 20% higher for men compared to women (P<.01). Total, training, and match injury incidence were 30%-40% higher in men (P≤.04) mainly due to a 4.82 (95% confidence interval [CI] 2.30-10.08) times higher incidence of contusions, as there were no differences in the incidence of muscle and joint/ligament injuries (P≥.44). The total number of absence days was 21% larger in women owing to a 5.36 (95% CI 1.11-25.79) times higher incidence of severe knee and ankle ligament injuries. Hamstring strains and pubalgia cases were 1.93 (95% CI 1.16-3.20) and 11.10 (95% CI 1.48-83.44) times more frequent in men, respectively; whereas quadriceps strains, anterior cruciate ligament ruptures, and ankle syndesmosis injuries were 2.25 (95% CI 1.22-4.17), 4.59 (95% CI 0.93-22.76), and 5.36 (95% CI 1.11-25.79) times more common in women, respectively. In conclusion, prevention strategies should be tailored to the needs of male and female football players, with men more predisposed to hamstring strains and hip/groin injuries, and women to quadriceps strains and severe knee and ankle ligament injuries. © 2017 John Wiley & Sons A/S.

This paper describes the development of a community mental health project in a local football stadium. Funded for three years by the Laureus Foundation's 'Sport for Good' initiative, the project provides mental health promotion and mental health awareness input targeted initially at young men, a group who are often very difficult to engage in this type work. Using group interventions and utilising football as a metaphor, the project helps young men address issues around depression, self-esteem and inclusion, and addresses the subject of suicide which remains the second biggest cause of death in young men in Britain. The paper describes the development of the project, the structure of the groups and the evaluation of the first two groups to complete the process. The work takes place in the Moss Rose stadium, home of Macclesfield Town, a team in the English Football League.

A survey of “mental hardiness” and “mental toughness” in professional male football players

PubMed Central

2014-01-01

Background It is not uncommon for chiropractors to be associated with sports teams for injury prevention, treatment, or performance enhancement. There is increasing acceptance of the importance of sports psychology in the overall management of athletes. Recent findings indicate mental hardiness can be determined reliably using specific self-assessment questionnaires. This study set out to investigate the hardiness scores of professional footballers and examine the correlation between two questionnaires. It also included a mental hardiness rating of players by two coaches, and examined differences in hardiness and mental toughness between national and international players. Methods Two self-assessment questionnaires (modified Sports Mental Toughness Questionnaire [SMTQ-M] and Psychological Performance Inventory [PPI-A]) were completed by 20 male professional footballers. Two coaches, independently rated each player. A percentage score from each questionnaire was awarded each player and an average score was calculated ({SMTQ-M % + PPI-A %} ÷ 2). The PPI-A and SMTQ-M scores obtained for each player were analysed for correlation with Pearson’s correlation coefficient. Cohen’s kappa inter-reliability coefficient was used to determine agreement between coaches, and between the players’ hardiness scores and coaches’ ratings. The independent t-test was used to examine differences between national and international players. Results The players’ scores obtained from PPI-A and SMTQ-M correlated well (r = 0.709, p < 0.001). The coaches ratings showed significant, weak to moderate agreement (Cohen's kappa = 0.33). No significant agreement was found between player self-assessments and coaches’ ratings. The average ({SMTQ-M % + PPI-A %} ÷ 2) mean score was 77% (SD = 7.98) with international players scoring 7.4% (p = 0.04) higher than non-international players. Conclusions The questionnaires (SMTQ-M and PPI-A) correlated well in their outcome scores. These findings

The incidence and severity of football-related injuries has been found to differ strongly between professional leagues from different countries. The aims of this study were to record the incidence, type and severity of injuries in Kosovarian football players and investigate the relationship between injury incidence rates (IRs), players' age and playing positions. Players' age, anthropometric characteristics and playing positions, training and match exposure as well as injury occurrences were monitored in 11 teams (143 players) of Kosovo's top division during the 2013/14 season. The exact type, severity and duration of football-related injuries were documented following International Federation of Football Associations (FIFA) recommendations. A total of 272 injuries were observed, with traumatic injuries accounting for 71 %. The overall injury IR was 7.38 (CI: 7.14, 7.63) injuries per 1,000 exposure hours and ~11x lower during training as opposed to matches. Strains and ruptures of thigh muscles, ligamentous injuries of the knee as well as meniscus or other cartilage tears represented the most frequent differential diagnoses. While no statistical differences were found between players engaged in different playing positions, injury IR was found to be higher by 10-13 % in younger (IR = 7.63; CI: 7.39, 7.87) as compared to middle-aged (IR = 6.95; CI: 6.41, 7.54) and older players (IR = 6.76; CI: 5.71, 8.00). The total injury IR in elite football in Kosovo is slightly lower than the international average, which may be related to lesser match exposure. Typical injury patterns agree well with previously reported data. Our finding that injury IR was greater in younger players is related to a higher rate of traumatic injuries and may indicate a more aggressive and risky style of play in this age group.

Evaluating a standardised tool to explore the nature and extent of foot and ankle injuries in amateur and semi-professional footballers.

Most studies of football injuries include professional players and data have been collected in without a single validated, standardised tool. We aimed to develop a new standardised questionnaire for assessing injuries among non-professional footballers and pilot its use. A questionnaire was developed using input from footballers, healthcare professionals and triangulation from the literature. The new tool was piloted among players representing amateurs and semi-professionals. Their comments were used iteratively to improve the instrument. The development phase produced a 33-item questionnaire collecting quantitative and qualitative data. In the pilot phase, 42 questionnaires were distributed, 34 (81%) returned. Respondents reported total of 273 football-related injuries, 114 affecting the foot/ankle (70 at the ankle and 44 at the foot). In total, 44% of respondents had suffered one or more foot/ankle injuries in the past 12 months. We developed a new standardised tool which we found to be well-completed by young male footballers in semi-professional and amateur settings with an excellent response rate. Our results suggested that foot/ankle injuries were common, larger studies in non-professionals are needed to identify risk factors for injury and develop pragmatic advice for prevention.

Variations in rates of growth and development in young football players can influence relationships among various fitness qualities. To investigate the relationships between repeated-sprint ability and other fundamental fitness qualities of acceleration, agility, explosive leg power, and aerobic conditioning through the age groups of U11 to U18 in highly trained junior football players. Male players (n = 119) across the age groups completed a fitness assessment battery over two testing sessions. The first session consisted of countermovement jumps without and with arm swing, 15-m sprint run, 15-m agility run, and the 20-m Shuttle Run (U11 to U15) or the Yo-Yo Intermittent Recovery Test, Level 1 (U16 to U18). The players were tested for repeated-sprint ability in the second testing session using a protocol of 6 × 30-m sprints on 30 s with an active recovery. The correlations of repeated-sprint ability with the assorted fitness tests varied considerably between the age groups, especially for agility (r = .02 to .92) and explosive leg power (r = .04 to .84). Correlations of repeated sprint ability with acceleration (r = .48 to .93) and aerobic conditioning (r = .28 to .68) were less variable with age. Repeated-sprint ability associates differently with other fundamental fitness tests throughout the teenage years in highly trained football players, although stabilization of these relationships occurs by the age of 18 y. Coaches in junior football should prescribe physical training accounting for variations in short-term disruptions or impairment of physical performance during this developmental period.

Youth football programs across the United States represent an at-risk population of approximately 3.5 million athletes for sports-related concussions. The frequency of concussions in this population is not known. Descriptive epidemiology study. Over an 11-year span from January 2002 to December 2012, the authors reviewed the concussions sustained by athletes aged 5 to 13 years while playing football, as evaluated in emergency departments (EDs) in the United States and captured by the National Electronic Injury Surveillance System (NEISS) database of the US Consumer Product Safety Commission. There were 2028 (national estimate, 49,185) young football players evaluated in NEISS EDs with concussion from 2002 to 2012. There were 1987 (97.9%) males and 41 (2.1%) females, with a mean age of 11.2 years. The total number of concussions reported increased with age and by year. The majority of concussions were treated in the outpatient setting, with 1878 (91.7%) being treated and released. The total number of head-to-head injury mechanisms mirrored the total number of concussions by year, which increased throughout the 11-year span. The total number of players experiencing a loss of consciousness increased throughout the study period but did not match the total number of concussions over the 11-year time period. Fractures occurred in 11 (0.5%) patients, with 2 being severe (1 skull fracture and 1 thoracic compression fracture). Within the 5- to 13-year age range, there were a significant number of young athletes who presented to EDs with concussion as a result of playing organized football. Older children may be at greater risk for sustaining concussions, fractures, and catastrophic injuries while playing football when compared with younger children. Younger children are more susceptible to long-term sequelae from head injuries, and thus, improved monitoring systems for these athletes are needed to assist in monitoring patterns of injury, identifying risk factors, and

Football (soccer) betting, as a strategic form of betting, became one of the favorite wagers for pathological gamblers. Previous studies demonstrated the psychological and biological significance of the 'illusion of control' (personal control) and 'near miss' results in gambling. In our study, we explored whether knowledge and expertise of pathological sports gamblers can ensure a successful bet. Participants were divided into three groups of individuals - pathological gamblers, amateurs and laypersons - and were asked to predict in advance the general result and the exact result of football matches in the European Champions League Round of 16. The 165 participants included 53 pathological sports gamblers (52 males and 1 female), 78 laypersons (45 females and 33 males) and 34 amateurs (all males). After a thorough statistical analysis, we found no significant differences between the groups, no matter what kind of previous knowledge they had acquired. This study demonstrates that the 'illusion of control' of pathological gamblers, attained by knowledge of the game and its latest data and information (especially in a strategic gamble as football betting), has no factual background. Moreover, our study demonstrates without a doubt that there is no significant difference between the male pathological sports gamblers group and the male/female laypersons group. Copyright © 2012 S.

The warm-up programme "FIFA 11+" has been shown to reduce football injuries in different populations, but so far veteran players have not been investigated. Due to differences in age, skill level and gender, a simple transfer of these results to veteran football is not recommended. The purpose of this study was to investigate the preventive effects of the "FIFA 11+" in veteran football players. Twenty veteran football teams were recruited for a prospective 9-month (1 season) cluster-randomised trial. The intervention group (INT, n = 146; 45 ± 8 years) performed the "FIFA 11+" at the beginning of each training session, while the control group (CON, n = 119; 43 ± 6 years) followed its regular training routine. Player exposure hours and injuries were recorded according to an international consensus statement. No significant difference was found between INT and CON in overall injury incidence (incidence rate ratio [IRR]: 0.91 [0.64-1.48]; P = 0.89). Only severe injuries reached statistical significance with higher incidence in CON (IRR: 0.46 [0.21-0.97], P = 0.04). Regular conduction (i.e. once a week) of the "FIFA 11+" did not prevent injuries in veteran footballers under real training and competition circumstances. The lack of preventive effects is likely due to the too low overall frequency of training sessions.

BACKGROUND Repeated head trauma has been associated with risk of neurodegenerative diseases. Few studies have evaluated the long-term risk of neurodegenerative diseases in collision sports like football. OBJECTIVE To assess whether athletes who played American varsity high-school football between 1956 and 1970 have an increased risk of neurodegenerative diseases later in life. PATIENTS AND METHODS We identified all male varsity football players between 1956 and 1970 in the public high schools of Rochester, Minnesota, compared to non-football-playing male varsity swimmers, wrestlers or basketball players. Using the records-linkage system of the Rochester Epidemiology Project, we ascertained the incidence of late-life neurodegenerative diseases: dementia, parkinsonism, or amyotrophic lateral sclerosis. We also recorded medical record-documented head trauma during high school years. RESULTS We identified 296 varsity football players and 190 athletes engaging in other sports. Football players had an increased risk of medically documented head trauma, especially if they played football for more than one year. Compared to non-football athletes, football players did not have an increased risk of neurodegenerative disease overall, nor the individual conditions of dementia, parkinsonism, or amyotrophic lateral sclerosis. CONCLUSION In this community based study, varsity high school football players from 1956 to 1970 did not have an increased risk of developing neurodegenerative diseases compared with athletes engaged in other varsity sports. This was from an era where there was a generally nihilistic view of concussion dangers, less protective equipment and without prohibition of spearing (head-first tackling). However, size and strength of players from prior eras may not be comparable to current high-school athletes. PMID:27979411

2015-09-01

The aim of the present investigation was to identify possible factors associated with returning to football on an average 3.2 ± 1.4 years after anterior cruciate ligament (ACL) reconstruction in both male and female football players. The players were recruited from a patient database of football players that have undergone an ACL reconstruction between 2004 and 2007 at the Capio Artro Clinic, Sophiahemmet in Stockholm, Sweden. Special attention was paid to gender, age, type of graft for ACL reconstruction, associated injuries, anterior knee laxity, thigh muscle torques and symptoms/problems during, and/or after physical activity. In the beginning of the summer of 2009, 205 players (37.9 %) out of 541 players filled out a questionnaire designed to evaluate physical activity and knee function in a sports-specific setting. A detailed dropout analysis showed that females responded to a higher degree than males. No other significant differences between responders and non-responders were found. Fifty-four per cent (n = 111) had returned to football, and 46 % (n = 94) had not. Using logistic regression analyses, we found that the female gender (p = 0.036, OR 0.518), cartilage injury (p = 0.013, OR 0.368), and pain during physical activity (p = 0.002, OR 0.619) were significant negative predictors for returning to football after ACL reconstruction and rehabilitation. For players with all three significant factors, only 10 % returned to football compared to 76.5 % of those without any of these factors. Female gender, cartilage injury, and knee pain during physical activity were independent negative predictors for returning to football after ACL reconstruction. At a mean follow-up of 3.2 ± 1.4 years after ACL reconstruction, pain during physical activity was reported to be the most common symptom/problem in football players. The clinical relevance of this study is to improve the treatment of ACL injured football players focusing on female gender and knee pain. Furthermore

Football fans and food: a case study of a football club in the English premier league.

Although there is growing awareness of the impact of diet on health, little attention has been given to the food available in our sports stadia. We used a football club (Citygrene FC) - Citygrene is a fictional name - in the English Premier League as a case study to examine the attitudes of male and female football supporters to the food and drink available at their home stadium (Citygrene Stadium). The research design used five focus groups of male and female fans. The discourse was audiotaped, transcribed, coded and analysed for themes. A football stadium in the English Premier League, England. The participants were season ticket holders drawn from two stands at Citygrene Stadium. The research showed a high level of dissatisfaction with the food and drink supplied. There were key differences in the views of the male and female participants in the focus groups, with the women more concerned about wider issues such as the lack of healthy food. Both men and women were aware of their role as consumers and felt that there was an opportunity for Citygrene to improve their catering profits, if they provided a better selection of food and drink and an improved service. The study shows that there is a demand for healthier food options (and a wider choice of food and drink in general), which may provide an economic opportunity for stadium and catering managers. In addition, a stadium may be considered a potential 'healthy setting', which can serve as a supportive environment for healthier food choices.

Factors that affect food choices include the physical and social environments, quality, quantity, perceived healthfulness, and convenience. The personal food choice process was defined as the procedures used by athletes for making food choices, including the weighing and balancing of activities of daily life, physical well-being, convenience, monetary resources, and social relationships. To develop a theoretical model explaining the personal food choice processes of collegiate football players. Qualitative study. National Collegiate Athletic Association Division II football program. Fifteen football players were purposefully sampled to represent various positions, years of athletic eligibility, and ethnic backgrounds. For text data collection, we used predetermined, open-ended questions. Data were analyzed using the constant comparison method. The athletes' words were used to label and describe their interactions and experiences with the food choice process. Member checks and an external audit were conducted by a qualitative methodologist and a nutrition specialist, and the findings were triangulated with the current literature to ensure trustworthiness of the text data. Time was the core category and yielded a cyclic graphic of a theoretical model for the food choice system. Planning hydration, macronutrient strategies, snacks, and healthful food choices emerged as themes. The athletes planned meals and snacks around their academic and athletic schedules while attempting to consume foods identified as healthful. Healthful foods were generally lower in fat but high in preferred macronutrients. High-protein foods were the players' primary goal; carbohydrate consumption was secondary. The athletes had established plans to maintain hydration. Professionals may use these findings to implement educational programs on food choices for football players.

Upper extremity sensorimotor control among collegiate football players.

PubMed

Laudner, Kevin G

2012-03-01

Injuries stemming from shoulder instability are very common among athletes participating in contact sports, such as football. Previous research has shown that increased laxity negatively affects the function of the sensorimotor system potentially leading to a pathological cycle of shoulder dysfunction. Currently, there are no data detailing such effects among football players. Therefore, the purpose of this study was to examine the differences in upper extremity sensorimotor control among football players compared with that of a control group. Forty-five collegiate football players and 70 male control subjects with no previous experience in contact sports participated. All the subjects had no recent history of upper extremity injury. Each subject performed three 30-second upper extremity balance trials on each arm. The balance trials were conducted in a single-arm push-up position with the test arm in the center of a force platform and the subjects' feet on a labile device. The trials were averaged, and the differences in radial area deviation between groups were analyzed using separate 1-way analyses of variance (p < 0.05). The football players showed significantly more radial area deviation of the dominant (0.41 ± 1.23 cm2, p = 0.02) and nondominant arms (0.47 ± 1.63 cm2, p = 0.03) when compared with the control group. These results suggest that football players may have decreased sensorimotor control of the upper extremity compared with individuals with no contact sport experience. The decreased upper extremity sensorimotor control among the football players may be because of the frequent impacts accumulated during football participation. Football players may benefit from exercises that target the sensorimotor system. These findings may also be beneficial in the evaluation and treatment of various upper extremity injuries among football players.

The postmodernity of football hooliganism.

1997-12-01

By using a 'cultural' definition of 'postmodernism' (derived from Jameson and Martin) in which postmodernism is regarded as the transgression of modern boundaries, this article traces the emergence of postmodern aspects to violent male fandom at football games since the 1960s. It is argued that at games, male fans have created imaginary masculine and national boundaries by which they have affirmed their identities but that in fighting they have sought to breach these boundaries in postmodern fashion.

This study examined the intermittent exercise performance and cardiovascular health profile in elite female football players in comparison to untrained young women, as well as a subgroup subjected to football training 2x1 h · week(-1) for 16 weeks. Twenty-seven Danish national team players (elite trained, ET) and 28 untrained women (UT) underwent dual-energy X-ray absorptiometry-scanning (DXA), comprehensive transthoracic echocardiography, treadmill and Yo-Yo Intermittent Endurance level 2 (IE2) testing. Eight women in UT were also tested after the football training period. Maximal oxygen uptake rate (VO2max), peak ventilation and peak lactate were 40, 18 and 51% higher (P< 0.01) in ET than UT, respectively. Cardiac dimensions and function were greater in ET than UT, with left ventricular diastolic diameter, right ventricular diastolic diameter, tricuspid annular plane systolic excursion (TAPSE) and peak transmitral flow in early diastole divided by peak transmitral flow velocity in late diastole during atrial contraction (E/A-ratio) being 13, 19, 27 and 41%, respectively, greater in ET than UT (P< 0.001 to< 0.05). Yo-Yo IE2 performance was 7-fold higher in ET than UT (1772 ± 508 vs. 234 ± 66 m, P< 0.001), fat mass was 51% lower (P< 0.001) and high density lipoprotein (HDL) cholesterol levels were 20% higher (P< 0.01). Sixteen weeks of football elevated VO2max and Yo-Yo IE2 performance by 16 and 40%, respectively, and lowered fat mass by 6%. Cardiac function was markedly improved by 16 weeks of football training with 26 and 46% increases in TAPSE and E/A ratio, respectively, reaching levels comparable to ET. In summary, elite female football players have a superior cardiovascular health profile and intermittent exercise performance compared to untrained controls, but short-term football training can markedly improve the cardiovascular health status.

Nutrition and Gaelic football: review, recommendations, and future considerations.

PubMed

Beasley, Kevin J

2015-02-01

Gaelic football is the second most popular team sport in Ireland in terms of participation. However, very little research exists on the nutritional considerations for elite male Gaelic footballers. Gaelic football is an intermittent type field game played by two teams of fifteen players. Although amateurs, elite players may train and compete 4-5 times per week and may play for several teams. Research suggests that elite footballers are similar anthropometrically and in fitness to professional soccer players. Work-rate analysis shows that footballers experience longer durations of high-intensity (HI) activity (5-7s) and shorter rest durations than soccer players. Recent data suggests that half-forward/backs perform a greater amount of HI work during games than players in other positions. Fatigue is apparent between the first and second halves and the first and fourth quarters. The limited amount of nutritional studies conducted implies that footballers may be deficient in energy intake and may be at the lower end of recommended carbohydrate intakes to support training. A wide variety of sweat rates have been measured during training, demonstrating the importance of individual hydration strategies. Ergogenic aids such as creatine and caffeine may prove beneficial to performance, although data are extrapolated from other sports. Due to the lack of research in Gaelic football, further population specific studies are required. Future areas of research on the impact of nutrition on Gaelic football performance are examined. In particular, the creation of a test protocol mimicking the activity patterns and intensity of a Gaelic football game is warranted.

To address football players' comfort with care provided by same-sex and opposite-sex athletic trainers for sex-specific and non-sex-specific injuries and conditions through the lens of role congruity theory. Cross-sectional study for the quantitative data and qualitative study for the qualitative data. Two National Collegiate Athletic Association Division I Football Bowl Series university football programs. Male football players within the 2 university programs. We replicated existing methods and an existing survey to address male football players' comfort levels. Additionally, an open-ended question was used to determine male football players' perceptions of female athletic trainers. Paired-samples t tests were conducted to identify differences between the responses for the care given by a male athletic trainer and for the care given by a female athletic trainer. Three categories were analyzed: general medical conditions, psychological conditions, and sex-specific injuries. The qualitative data were coded and analyzed using content analysis. Male football players were more comfortable with treatment by a male athletic trainer (mean = 3.61 +/- 1.16) for sex-specific injuries and conditions than they were with treatment by a female athletic trainer (mean = 2.82 +/- 1.27; P < .001). No significant results were found for comfort with overall psychological conditions, although a female athletic trainer was preferred over a male athletic trainer for the treatment of depression (mean = 3.71 +/- 1.07 versus mean = 3.39 +/- 1.16, respectively; P < .001). Qualitative data provided support for role congruity theory. Both quantitative and qualitative evidence were provided for the support of role congruity theory.

To increase movement capacity and to reduce injury risk in young soccer players by implementing a special functional exercise program based on functional movement screen (FMS) and correctives. 67 young male athletes 14-19 years of age from a Super League Football Club Academy participated in the study. Functional movement patterns were evaluated with FMS assessment protocol. Deep squat, hurdle step, inline lunge, shoulder mobility, active straight leg raise, trunk stability push-up, and rotatory stability were examined in FMS. Considering the FMS scores the number of intervention and control groups were defined as 24 and 43, respectively. Intervention program was composed of 1 hr twice a week sessions in total of 12 weeks with 4 weeks of mobility, 4 weeks of stability, and 4 weeks of integration exercises. At the end of 12-week intervention and control groups were re-evaluated with FMS protocol. Contact and noncontact sports injuries recorded during one season. In intervention group there was statistically significant difference in increase in total FMS scores ( P <0.01), deep squat ( P ≤0.001), hurdle step ( P <0.05), inline lunge ( P <0.01), and trunk stability push-up ( P <0.01). In control group total FMS, deep squat, and trunk stability push-up scores increased with a statistical difference ( P <0.01, P <0.05, P ≤0.01, respectively). The incidence of noncontact injury in control group was higher than intervention group ( P <0.05). Periodic movement screening and proper corrections with functional training is valuable in order to create better movement capacity to build better physical performance and more effective injury prevention.

Injury has been identified as a potential risk factor for osteoarthritis. However, no previous study has addressed playing-career injuries and subsequent osteoarthritis in a large sample of former athletes. The purpose of this study was to describe the prevalence and determinants of arthritis and osteoarthritis in retired professional football players. Self-reported arthritis prevalence and retrospectively-recalled injury history were examined in a cross-sectional survey of 2,538 retired football players. Football players reported a high incidence of injury from their professional playing days (52.8% reported knee injuries, 74.1% reported ligament/tendon injuries, and 14.2% reported anterior cruciate ligament tears). For those under 60 years, 40.6% of retired NFL players reported arthritis, compared with 11.7% of U.S. males (prevalence ratio = 3.5, 95% CI: 3.3 to 3.7). Within the retired NFL player cohort, osteoarthritis was more prevalent in those with a history of knee injury (prevalence ratio = 1.7, 95% CI: 1.5 to 1.9) and ligament/tendon injury (prevalence ratio = 1.6, 95% CI: 1.4 to 1.9). In males under the age of 60, arthritis is over 3 times more prevalent in retired NFL players than in the general U.S. population. This excess of early-onset arthritis may be due to the high incidence of injury in football.

Summary Background Football is a high-speed contact sport and the risk of injury is high. The objective of this study was to compare the two main divisions (A1 and A2) of the São Paulo Football Championship and to perform a correlation analysis of the variables studied. Methods A prospective study was conducted using an electronic questionnaire previously developed by the Medical Committee of the São Paulo Football Federation. The questionnaire was sent to the doctors of the teams playing in the A1 and A2 divisions of the São Paulo Football Championship after each round. Setting: 2016 São Paulo Football Championship. Results The comparison of divisions A1 and A2 showed few significant differences among the various variables analysed in this study. The only significant differences were for right-side involvement in division A1 (p=0.044) and morning matches in division A2 (p<0.001). The correlation analysis of the variables studied showed expected associations, including sprains with a higher rate of need for surgery, ultrasound with muscle strains and moderate severity (8–28 days lost) with muscle strains. Conclusion Despite the differences between the two divisions regarding budgets and team characteristics, there was a little difference in the variables analysed and there were associations such as sprains with a higher rate of need for surgery, ultrasound with muscle strains and moderate severity (8–28 days lost) with muscle strains. Level of evidence II b, individual cohort study. PMID:29387647

Design: Cross-sectional study for the quantitative data and qualitative study for the qualitative data. Setting: Two National Collegiate Athletic Association Division I Football Bowl Series university football programs. Patients or Other Participants: Male football players within the 2 university programs. Data Collection and Analysis: We replicated existing methods and an existing survey to address male football players' comfort levels. Additionally, an open-ended question was used to determine male football players' perceptions of female athletic trainers. Paired-samples t tests were conducted to identify differences between the responses for the care given by a male athletic trainer and for the care given by a female athletic trainer. Three categories were analyzed: general medical conditions, psychological conditions, and sex-specific injuries. The qualitative data were coded and analyzed using content analysis. Results: Male football players were more comfortable with treatment by a male athletic trainer (mean  =  3.61 ± 1.16) for sex-specific injuries and conditions than they were with treatment by a female athletic trainer (mean  =  2.82 ± 1.27; P < .001). No significant results were found for comfort with overall psychological conditions, although a female athletic trainer was preferred over a male athletic trainer for the treatment of depression (mean  =  3.71 ± 1.07 versus mean  =  3.39 ± 1.16, respectively; P < .001). Qualitative data provided support for role congruity theory. Conclusions: Both quantitative and qualitative

Previous research has claimed neuropsychological impairment occurs as a result of professional and amateur football play, and, specifically, football heading. However, much of this research exhibits substantial methodological problems. By investigating less committed amateur level footballers, the current study sought to gain some insight into the developmental history of any neuropsychological consequences of football play. University football, rugby and noncontact sports players were compared on a range of biographical and neuropsychological test variables. While playing their chosen sports, rugby players sustained many more head injuries than footballers and noncontact sportsmen, but footballers did not sustain significantly more head injuries than noncontact sportsmen. The number of head injuries sustained predicted Trails B and TAP Divided Attention latencies in a positive fashion. After controlling for the number of head injuries sustained, sport group effects were detected with TAP Divided Attention accuracy scores, with footballers exhibiting poorest performance. After controlling for the number of head injuries sustained, the total amount of heading done by footballers predicted the number of Wisconsin Card Sorting category shifts in a negative fashion. Nevertheless, over interpretation of all of these results should be resisted because of the exploratory nature of the analyses and the possibility that the sport groups may differ in ways other than just the nature of their sports activities.

Biceps femoris and semitendinosus—teammates or competitors? New insights into hamstring injury mechanisms in male football players: a muscle functional MRI study

2014-01-01

Background The hamstring injury mechanism was assessed by investigating the exercise-related metabolic activity characteristics of the hamstring muscles using a muscle functional MRI (mfMRI) protocol. Methods 27 healthy male football players and 27 football players with a history of hamstring injuries (recovered and playing fully) underwent standardised mfMR Imaging. The mfMRI protocol consisted of a resting scan, a strenuous bilateral eccentric hamstring exercise and a postexercise scan. The exercise-related T2 increase or the signal intensity shift between both scans was used to detect differences in metabolic activation characteristics (1) between the different hamstring muscle bellies and (2) between the injury group and the control group. Results A more symmetrical muscle recruitment pattern corresponding to a less economic hamstring muscle activation was demonstrated in the formerly injured group (p<0.05). The injured group also demonstrated a significantly lower strength endurance capacity during the eccentric hamstring exercise. Conclusions These findings suggest that the vulnerability of the hamstring muscles to football-related injury is related to the complexity and close coherence in the synergistic muscle recruitment of the biceps femoris and the semitendinosus. Discrete differences in neuromuscular coordination and activity distribution, with the biceps femoris partly having to compensate for the lack of endurance capacity of the semitendinosus, probably increase the hamstring injury risk.

The functional asymmetry of the lower limbs has been regarded as a relevant factor of the performance of football players. We purposed to ascertain whether a specific technical training programme for the non-preferred foot has implications in the increasing utilisation rate of the respective member during the game. Young football players (n = 71) were randomly divided into experimental group (N = 35; 14.37 ± 1.94 years) and control group (N = 36; 14.50 ± 1.81 years). The study was developed into three stages: first, assessment of the index utilisation of both limbs during the game; second, application of a technical training programme that includes the drilling of specific motor skills exclusively directed to the non-preferred foot; and third, assessment of the new rate of both limbs' utilisation after the predefined six months. The main findings were: (1) the use of the non-preferred foot increased significantly with the technical training programme in the experimental group and remained constant in the control group; (2) the use of the preferred foot decreased significantly in the experimental group and remained similar in control group. We concluded that a systematic and specific technical training for the non-preferred foot increases its use and reduces functional asymmetry in game situation, consequently improving the player's performance.

Welfare Reform and Labor Force Exit by Young, Low-Skilled Single Males.

PubMed

Groves, Lincoln H

2016-04-01

While the labor market woes of low-skilled male workers in the United States over the past several decades have been well documented, the academic literature identifying causal factors leading to declines in labor force participation (LFP) by young, low-skilled males remains scant. To address this gap, I use the timing and characteristics of welfare-reform policies implemented during the 1990s and fixed-effects, instrumental variable regression modeling to show that policies seeking to increase LFP rates for low-skilled single mothers inadvertently led to labor force exit by young, low-skilled single males. Using data from the Current Population Survey and a bundle of work inducements enacted by states throughout the 1990s as exogenous variation in a quasi-experimental design, I find that the roughly 10 percentage point increase in LFP for low-skilled single mothers facilitated by welfare reform resulted in a statistically significant 2.8 percentage point decline in LFP for young, low-skilled single males. After conducting a series of robustness checks, I conclude that this result is driven entirely by white males, who responded to welfare-reform policies with a 3.7 percentage point decline in labor supply. Young black males, as well as other groups of potentially affected workers, appear to be uninfluenced by the labor supply response of less-educated single mothers to welfare reform. Impacts on young, single white males are large and economically significant, suggesting that nearly 150,000 males departed the formal labor market in response to directed welfare-reform policies.

To profile training habits and injuries in football players participating in a national Masters tournament. A cross-sectional retrospective study design was used to survey male football players attending the 2008 New Zealand Masters Games. Information regarding player demographics, football injuries, football related training, and risk factors for injury were collected. 199 Players were recruited, with a median age of 44 yrs (range 35-73) and a median football playing history of 15 yrs (range 0-66). Irrespective of age, 112 (84%) players included a warm-up and 104 (78%) included a stretching regime in their regular training programme. In the 12 months prior to the tournament, 128 football related injuries were reported by 93 players (64 injuries/100 players or 46 injured players/100 players). The most frequently injured region was the lower limb; specifically the lower leg (n=23), ankle (n=18), hamstring (n=17), knee (n=15), and Achilles tendon (n=15). This study provides a preliminary insight into the training habits and injury profiles of Masters football players. Despite all players including some form of injury prevention strategy in their training, a significant number of players experienced an injury in the 12 months prior to the tournament.

Rugby union football continues to gain in popularity in the United States. Both men's and women's clubs have been established at several colleges and universities. There has been substantial growth in the number of high school rugby football clubs in recent years. With the increase in numbers of young participants in this sport, it is important that great efforts be mounted to attempt to control the injury rates and severity of injuries in rugby football. Players and coaches must be knowledgeable of the rules of the game, and referees must strictly enforce these rules. Physicians and dentists should be involved in educating parents, coaches, players, and school officials about the inherent risks of injury and the means for injury prevention. Medical personnel must also be instrumental in educating players about alcohol abuse/addiction. Rugby players should be encouraged to use the limited protective gear that is allowed: wraps, tape, joint sleeves, scrum caps, and facial grease to prevent lacerations. Mouthguards are strongly recommended at any level of play and should be mandated. The use of helmets, face masks, and shoulder pads has been suggested by some authors. Such rule changes could actually increase injury rates and severity, because this equipment could be used as weapons as they are in American football. It is recommended that rugby clubs purchase or build equipment to practice scrummage skills. Coaches should be experienced and attend clinics or complete video courses on medical emergencies and safe techniques of the game. Injury frequency and severity can be decreased by adequate preseason training and conditioning, proper tackling and falling techniques, strengthening of neck muscles, and allowing only experienced, fit athletes to play in the front row. Medical surveillance must be improved at matches and, ideally, at practice sessions. At present, it is common for no emergency medical personnel or physicians to be present at matches in the United

Tibial shaft fractures in football players

Background Football is officially the most popular sport in the world. In the UK, 10% of the adult population play football at least once a year. Despite this, there are few papers in the literature on tibial diaphyseal fractures in this sporting group. In addition, conflicting views on the nature of this injury exist. The purpose of this paper is to compare our experience of tibial shaft football fractures with the little available literature and identify any similarities and differences. Methods and Results A retrospective study of all tibial football fractures that presented to a teaching hospital was undertaken over a 5 year period from 1997 to 2001. There were 244 tibial fractures treated. 24 (9.8%) of these were football related. All patients were male with a mean age of 23 years (range 15 to 29) and shin guards were worn in 95.8% of cases. 11/24 (45.8%) were treated conservatively, 11/24 (45.8%) by Grosse Kemp intramedullary nail and 2/24 (8.3%) with plating. A difference in union times was noted, conservative 19 weeks compared to operative group 23.9 weeks (p < 0.05). Return to activity was also different in the two groups, conservative 27.6 weeks versus operative 23.3 weeks (p < 0.05). The most common fracture pattern was AO Type 42A3 in 14/24 (58.3%). A high number 19/24 (79.2%) were simple transverse or short oblique fractures. There was a low non-union rate 1/24 (4.2%) and absence of any open injury in our series. Conclusion Our series compared similarly with the few reports available in the literature. However, a striking finding noted by the authors was a drop in the incidence of tibial shaft football fractures. It is likely that this is a reflection of recent compulsory FIFA regulations on shinguards as well as improvements in the design over the past decade since its introduction. PMID:17567522

Gradual increase in the risk of match injury in Norwegian male professional football: a 6-year prospective study.

Bjørneboe, J; Bahr, R; Andersen, T E

2014-02-01

The aim of this study was to monitor injury incidence and pattern in Norwegian male professional football over six consecutive seasons and compare the risk of injury between the preseason and competitive season. All time loss injuries were recorded by the medical staff of each club. In total, 2365 injuries were recorded. The incidence of acute injuries was 15.9/1000 match hours [95% confidence interval (CI): 14.9-16.8], 1.9/1000 training hours (95% CI: 1.7-2.0), and 1.4 (95% CI: 1.3-1.5) overuse injuries/1000 h. A linear regression model found an annual increase of 1.06 acute match injuries/1000 h (95% CI: 0.40-1.73), corresponding to a total increase of 49% during the 6-year study period. When accounting for interteam variation and clustering effects using a general estimating equation model, the increase in injury incidence was 0.92 (95% CI: -0.11-1.95, P = 0.083). No difference in the risk of acute match injuries (rate ratio (RR): 0.86, 95% CI: 0.73-1.01), acute training injuries (RR: 1.16, 95% CI: 0.99-1.36), or overuse injuries (RR: 1.04, 95% CI: 0.89-1.21) was observed between the preseason and competitive season. In conclusion, the overall risk of acute match injuries in Norwegian male professional football increased by 49% during the study period, although this increase was not fully consistent across teams. We detected no change in the risk of training and overuse injuries or any difference between the preseason and competitive season. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The aim of this study was to evaluate longitudinal changes in the diffusion characteristics of brain white matter (WM) in collegiate athletes at three time points: prior to the start of the football season (T1), after one season of football (T2), followed by six months of no-contact rest (T3). Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints. Average diffusion values were obtained from statistically significant clusters for each individual. No athlete suffered a concussion during the study period. After one season of play (T1 to T2), we observed a significant increase in trace in a cluster located in the brainstem and left temporal lobe, and a significant increase in FA in the left parietal lobe. After six months of no-contact rest (T2 to T3), there was a significant decrease in trace and FA in clusters that were partially overlapping or in close proximity with the initial clusters (T1 to T2), with no significant changes from T1 to T3. Repetitive head impacts (RHI) sustained during a single football season may result in alterations of the brain's WM in collegiate football players. These changes appear to return to baseline after 6 months of no-contact rest, suggesting remission of WM alterations. Our preliminary results suggest that collegiate football players might benefit from periods without exposure to RHI.

Does Game Participation Impact Cognition and Symptoms in Elite Football Players?

To measure neurocognitive functioning in college and professional football players after game participation. Retrospective, cross-sectional cohort design. Ninety-four male university and professional football players. All participants completed Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) testing at baseline, and either at postconcussion (group 1) or postgame (group 2) participation. Results from the 5 ImPACT composite scores (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time and Impulse Control) and Total Symptom Score. Repeated-measures analysis of variance demonstrated a significant main effect for time (improvements) in 3 of 5 domains for the postconcussion group, but no improvements in the postgame group. The postconcussion group presented with significantly improved results on 4 of 5 ImPACT domains compared with the postgame group at the follow-up time interval. Participation in a football game with potential cumulative head contacts did not yield increased symptoms or cognitive impairment. However, the absence of improvement in cognitive functioning in noninjured football players, which was found in those players who were returned to play after an injury, may suggest that there is a measureable impact as a result of playing football.

Sagittal back motion of college football athletes and nonathletes.

The study was designed as an ex post facto study using volunteers. To compare sagittal back motion of male college athletes with that of nonathletes and to compare data from both groups with normative data. Few studies have evaluated athletic demands on the spine. Much of the information on athletic demands comes from electromyographic studies, flexibility comparisons, and lift task studies. Although these studies provide a basis for back testing and evaluation, they do not present direct evidence of athletic low back performance. Fifteen male college football athletes and 15 male college nonathletes volunteered for testing using the IsoStation B-200 BSCAN 2.0 protocol (Isotechnologies, Inc., Hillsborough, NC). Measures were recorded for range of motion, isometric flexion and extension, and moderate and high dynamic flexion and extension. Data were analyzed using multivariate analysis of variance. The results of Hotelling's multivariate test were significant. Univariate follow-up analysis showed that athletes had significantly better isometric flexion, isometric extension, moderate dynamic flexion, high dynamic flexion, and high dynamic extension. Athletic data were compared with the BSCAN population data at the 50th and 80th percentile. Athletes were significantly better (P < 0.007) for all variables at the 50th percentile and for all dynamic variables at the 80th percentile. Within the limitations of the study, college football athletes had better sagittal back motion strength and speed as tested with the B-200 than nonathletes. Population data for the B-200 were representative for nonathletes but nonrepresentative for football players.

Football with three ‘halves’: A qualitative exploratory study of the football3 model at the Football for Hope Festival 2010

The “football3” model refers to a restructuring of traditional football/soccer rules to bring social and developmental benefits to participating youth and their communities. The model incorporates three “halves”: pre-game discussion, football match, and post-game discussion. This study was carried out to shed light on the experiences of youth and adults with the football3 model at the Football for Hope Festival 2010. As an official 2010 FIFA World Cup event, the festival assembled 32 mixed-sex delegations of youth for cultural activities and a football tournament. The study's aim was to inform the model's future design and implementation. Twenty interviews, two focus group discussions, and participant observation were conducted. Findings highlight positive experiences with the model regarding cultural exchange and relationship building, Fair Play and social values, and gender integration. Challenges pertain to misunderstanding of the football3 model, tournament atmosphere, and skill level differences. Recommendations centre on systematically formulating desired outcomes, formalizing a curriculum and training plan, piloting football3 in a range of settings over an extended period of time, and emphasizing monitoring and evaluation to assess the model's effectiveness and impact. Future piloting and research should inform the potential scale-up of the model. PMID:27064214

In this paper we present a design for a Doppler football. The classic Doppler ball uses a piezo buzzer and 9-V battery inside a foam ball. In our Doppler football, the sound level is enhanced by directing the 2.8-kHz tone of the buzzer through a hollow cylinder to one end of the football, with an on-off switch placed at the other end. We discuss our device within the historical context of Doppler demonstrations that have evolved over the many decades since Doppler's discovery.

U.S. motor vehicle fatality trends in young Latino males.

PubMed

Vaca, Federico; Anderson, Craig L

2009-10-01

The Latino Epidemiologic Paradox describes favorable health profiles for Latinos compared to non-Latino Whites (NLW) despite poverty, low education, and low access to health care. An anomaly to this paradox is increased mortality of Latino adolescent and emerging adult males. Previous research shows motor vehicle crash fatalities bear a considerable proportion of the mortality burden attributed to this anomaly. Utilizing two U.S. data sources (CDC-WISQARS and NHTSA-FARS), graphical and linear regression methods were used to analyze crash fatality trends and changes in factors that influence crash injury fatality among young Latino males age 15-24. During 1999-2006, 59,719 motor vehicle fatalities occurred among Latino, NLW and Non-Latino Black (NLB) young males. Fatality rates were 37.7, 39.6, and 29.8 per 100,000 population/year for Latinos, NLW and NLB respectively. Over the study period, young Latino male mortality rates increased 27%. By 2006, fatality rates were 41.9, 38.3 and 27.8 per 100,000 population/year for Latinos, NLW and NLB respectively. Among driver fatalities, 43% Latino, 33% NLW and 27% NLB were restrained. Fifty-seven percent of Latino drivers had blood alcohol >or=0.01 g/dl (BAC+), as did 47% of NLW drivers and 42% of NLB drivers. Over the study period, BAC+ changed little among Latinos and NLW drivers but decreased among NLB drivers. Motor vehicle fatality rates for young Latino males are rising despite increasing restraint use and leveling driver BAC+. Without racial/ethnic specific exposure data, limitations exist in discerning the cause of diverging fatality trends and further understanding specific racial/ethnic group crash fatality disparities.

A multidimensional intergenerational model of young males' driving styles.

This study examines the associations between fathers' driving styles, the family's general and driving-related atmosphere, and the young drivers' motivations, on one hand, and young males' driving styles, on the other. The 242 father and son pairs that participated in the study independently completed several self-report questionnaires at different points in time within the first year after licensure of the young drivers. A structural equation model (SEM) was developed, in which the contribution of fathers' driving style and their sons' perceptions of the general family relations, the family climate for road safety (FCRS), and costs and benefits of driving, to the driving styles of the young male drivers was examined. The SEM estimation results show direct as well as indirect significant effects between the various dimensions. The FCRS factors of non-commitment and messages, and the cost of thrill, were found to be the strongest mediators between the fathers' driving style and the family cohesion, on one hand, and the driving style of the young driver, on the other. These results may be useful in pointing out directions for the development of interventions that could assist in reducing the involvement of youngsters in risky driving and car crashes, and encourage safe and considerate driving.

Fulcher, Mark L; Hanna, Chris M; Raina Elley, C

2010-01-01

The aim of this study was to evaluate the intra- and interrater reliability of handheld dynamometry (HHD) for measuring hip muscle strength in a sample of 30 healthy semi-professional adult male football players. The reliability of HHD had not been assessed in athletes who were likely to be stronger than populations tested previously. Maximal isometric strength of resisted hip flexion and adduction were measured. Mean strength ranged from 51.5 kg for dominant hip flexion to 26.7 kg for hip adduction at 90 degrees of hip flexion. Intrarater reliability intraclass correlation coefficients (ICCs) ranged from 0.70 to 0.89. ICCs for interrater reliability ranged from 0.66 to 0.87. As expected, muscle strength in this group of athletes was significantly higher than that of populations in which HHD reliability has been assessed. Despite this, muscle strength testing of hip flexor and adductor muscles can be performed with good to excellent intra- and interrater reliability in this population. Copyright (c) 2009.

The review describes the fitness and health effects of recreational football in women aged 18-65 years. The review documents that 2 × 1 h of recreational football training for 12-16 weeks causes marked improvements in maximal oxygen uptake (5-15%) and myocardial function in women. Moreover, mean arterial blood pressure was shown to decrease by 2-5 mmHg in normotensive women and 6-8 mmHg in hypertensive women. This review also show that short-term (< 4 months) and medium-term (4-16 months) recreational football training has major beneficial impact on metabolic health profile in women, with fat losses of 1-3 kg and improvements in blood lipid profile. Lastly, 2 × 1 h per week of recreational football training for women elevates lower extremity bone mineralisation by 1-5% and whole-body bone mineralization by 1-2% within 4-12-month interventions. These training adaptations are related to the high heart rates, high number of fast runs, and multiple changes of direction and speed occurring during recreational football training for untrained women. In conclusion, regular small-sided football training for women is an intense and versatile type of training that combines elements of high-intensity interval training (HIIT), endurance training and strength training, thereby providing optimal stimuli for cardiovascular, metabolic and musculoskeletal fitness. Recreational football, therefore, seems to be an effective tool for prevention and treatment of lifestyle diseases in young and middle-aged women, including hypertension, type 2 diabetes and osteopenia. Future research should elucidate effects of football training for elderly women, and as treatment and rehabilitation of breast cancer patients and other women patient groups.

Sharma, Kamal H; Jindal, Anchal

2014-01-01

Background: Several studies have demonstrated an association between androgenetic alopecia (AGA) and cardiovascular disease. Still controversies exist regarding the association. Are they truly associated? Objective: The purpose of the present study was to assess the prevalence of AGA and establish its association in young (<45 years) Asian Indian Gujarati male patients having coronary artery disease (CAD). Materials and Methods: Case-control prospective multicentric study was carried out on 424 men. Case group consisted of 212 male subjects having CAD (Group 1) and another 212, either sibling or first degree male relative of the case subjects (having no evidence of CAD) were considered as the control group (Group 2). Age, total cholesterol, incidence of diabetes mellitus, and hypertension were similar in both groups. The degree of alopecia was assessed using the Norwood-Hamilton scale for men. Statistical analysis was performed using Chi-square test. Results: AGA was found in 80 (37.73%) young CAD patients (Group 1), whereas 44 (20.7%) of patients had alopecia in the control group (Group 2). There was statistically significant association between male AGA and CAD (P = 0.001). Odds ratio was 2.70 (95% confidence interval [CI], 1.72 ± 4.26). Statistically significant association was found between high grade baldness (Grades IV-VII) and CAD in young men (P < 0.05). Odds ratio = 2.36 (95% CI, 1.108 ± 5.033). There is statistically significant association of AGA in young Asian Gujarati male with CAD and the prevalence of AGA in young CAD patient is 37.73%. Conclusion: This study implies early onset AGA in male is independently associated with CAD, though mechanisms need to be investigated. PMID:25114445

Statistically significant association was found between high grade baldness (Grades IV-VII) and CAD in young men (P < 0.05). Odds ratio = 2.36 (95% CI, 1.108 ± 5.033). There is statistically significant association of AGA in young Asian Gujarati male with CAD and the prevalence of AGA in young CAD patient is 37.73%. This study implies early onset AGA in male is independently associated with CAD, though mechanisms need to be investigated.

The aim of this study was to assess the early electrocardiogram (ECG) changes induced by physical training in preadolescent elite footballers. This study included 94 preadolescent highly trained male footballers (FG) competing in Serbian Football League (minimum of 7 training hours/week) and 47 age-matched healthy male controls (less than 2 training hours/week) (CG). They were screened by ECG and echocardiography at a tertiary referral cardio center. Sokolow-Lyon index was used as a voltage electrocardiographic criterion for left ventricular hypertrophy diagnosis. Characteristic ECG intervals and voltage were compared and reference range was given for preadolescent footballers. Highly significant differences between FG and CG were registered in all ECG parameters: P-wave voltage (p < 0.001), S-wave (V1 or V2 lead) voltage (p < 0.001), R-wave (V5 and V6 lead) voltage (p < 0.001), ECG sum of S V 1-2  + R V 5-6 (p < 0.001), T-wave voltage (p < 0.001), QRS complex duration (p < 0.001), T-wave duration (p < 0.001), QTc interval duration (p < 0.001), and R/T ratio (p < 0.001). No differences were found in PQ interval duration between these two groups (p > 0.05). During 6-year follow-up period, there was no adverse cardiac event in these footballers. None of them expressed pathological ECG changes. Benign ECG changes are presented in the early stage of athlete's heart remodeling, but they are not related to pathological ECG changes and they should be regarded as ECG pattern of LV remodeling.

  High-intensity sport training at the youth level has led to increased concern for overuse conditions. Few researchers have examined overuse conditions in youth sports.   To examine the rates, risks, and distributions of overuse conditions between youth and high school football players.   Descriptive epidemiologic study.   Youth and high school football teams.   The Youth Football Safety Study (YFSS) investigated youth football athletes from age 5 to 14 years. The National Athletic Treatment, Injury and Outcomes Network (NATION) focused on high school football athletes 14 to 18 years old. The YFSS data consisted of 210 team-seasons, and the NATION data consisted of 138 team-seasons.   Athletic trainers collected football injury and exposure data during the 2012 and 2013 seasons. Injury rates, risks, and distributions were calculated, with injury rate ratios, risk ratios, and injury proportion ratios with 95% confidence intervals (CIs) comparing youth and high school football players.   The YFSS reported 1488 injuries, of which 53 (3.6%) were overuse conditions. The NATION reported 12 013 injuries, of which 339 (2.8%) were overuse conditions. The overuse condition rate did not differ between high school and youth football (3.93 versus 3.72/10 000 athlete-exposures; injury rate ratio = 1.06; 95% CI = 0.79, 1.41). However, the 1-season risk of overuse condition was higher in high school than in youth football players (2.66% versus 1.05%; risk ratio = 2.53; 95% CI = 1.84, 3.47). Compared with high school football players, youth football players had greater proportions of overuse conditions that were nontime loss (ie, <24 hours participation-restriction time; 83.0% versus 67.0%; injury proportion ratio = 1.24; 95% CI = 1.07, 1.43) and affecting the lower extremity (92.5% versus 62.5%; injury proportion ratio = 1.48; 95% CI = 1.32, 1.65).   Overuse conditions may not present a primary concern in youth and high school football players.

Osteoarthritis in Football

2016-01-01

Football is currently the most popular sporting activity in the world. Multiple reports have shown that a high incidence of osteoarthritis is found in football players. Evidence clearly shows that traumatic injury significantly predisposes players for such pathophysiology. Injuries are frequent in amateur as well as professional football players, with knee and ankle accounting for the most severe injuries. Many professional athletes lose playing time due to injuries and many are forced into early retirement. Posttraumatic osteoarthritis is a common finding among ex-football players with numbers well above the normal population. Today’s surgical techniques are advanced and capable of restoring the joint to a certain extent. However, a restitution ad integrum is reached only in very rare cases. Professional football players that return to play after serious injuries perform their extremely strenuous activity on morphologically compromised joints. Incomplete rehabilitation and pressure to return to play after an injurious event clearly put the athlete at an even higher risk for joint degeneration. Prevention strategies, improved surgical management, strict rehabilitation, as well as future aspects such as early suppression of inflammation, personalized medicine, and predictive genomics DNA profiling are needed to reduce incidence and improve the health perspectives of football players.

The few studies that have assessed oral health in professional/elite football suggest poor oral health with minimal data on impact on performance. The aim of this research was to determine oral health in a representative sample of professional footballers in the UK and investigate possible determinants of oral health and self-reported impact on well-being, training and performance. Clinical oral health examination of senior squad players using standard methods and outcomes carried out at club training facilities. Questionnaire data were also collected. 8 teams were included, 5 Premier League, 2 Championship and 1 League One. 6 dentists examined 187 players who represented >90% of each senior squad. Oral health was poor: 37% players had active dental caries, 53% dental erosion and 5% moderate-severe irreversible periodontal disease. 45% were bothered by their oral health, 20% reported an impact on their quality of life and 7% on training or performance. Despite attendance for dental check-ups, oral health deteriorated with age. This is the first large, representative sample study in professional football. Oral health of professional footballers is poor, and this impacts on well-being and performance. Successful strategies to promote oral health within professional football are urgently needed, and research should investigate models based on best evidence for behaviour change and implementation science. Furthermore, this study provides strong evidence to support oral health screening within professional football. Published by the BMJ Publishing Group Limited.

Science and football: a review of applied research in the football codes.

PubMed

Reilly, Thomas; Gilbourne, David

2003-09-01

Over the last two decades there has been a growth in research directly related to football. Although most of this research is focused on soccer (association football), there has been a steady increase in publications related to the other football codes. There is evidence of more systematic training and selection influencing the anthropometric profiles of players who compete at the highest level. Fitness is being optimized to cope with match demands while accommodating the need for specific requirements of positional roles. There is evidence of work rate being higher in contemporary football games than in previous decades, with consequences for training and dietary practices. Notation analysis of actions during matches is now used regularly to provide detailed objective feedback on performance to players and coaches. Training regimens are designed for game-specific purposes where possible. Sports psychologists working in a football context have a more eclectic body of knowledge to draw from. In the professional soccer clubs, the rewards associated with a successful investment in youth academies have helped to focus attention on talent identification and development models. It is a challenge to those specializing in science and football to contribute to the success of such schemes.

Rehabilitation after Articular Cartilage Repair of the Knee in the Football (Soccer) Player

PubMed Central

Silvers, Holly Jacinda; Steinwachs, Matthias

2012-01-01

Background: Participation in football can put both male and female players at an increased risk for knee osteoarthritis. There is a higher prevalence of focal chondral defects in the knee of athletes compared to nonathletes. The management of chondral defects in the football player is complex and multifactorial. Objective: The aim of this study is to provide an overview of the current strategies for rehabilitation after articular cartilage repair of the knee in the football player. Design: A review of current literature and the scientific evidence for rehabilitation after articular cartilage repair of the knee. Conclusions: Articular cartilage repair has been shown to allow return to sport but rehabilitation timescales are lengthy. Successful rehabilitation for a return to football after articular cartilage repair of the knee requires the player to be able to accept the load of the sport. This necessitates a multidisciplinary approach to rehabilitation, especially in the transition from therapy to performance care. It should be recognized that not all players will return to football after articular cartilage repair. The evidence base for rehabilitative practice after articular cartilage repair is increasing but remains sparse in areas. PMID:26069608

The aim of the present study was to investigate the association between vitamin D receptor (VDR) gene polymorphisms and musculoskeletal injury (MI) in elite football players. In total, 54 male professional football players were recruited from an official Italian professional championship team between 2009 and 2013. The cohort was genotyped for the ApaI, BsmI and FokI polymorphisms and MI data were collected over four football seasons. No significant differences were identified among the genotypes in the incidence rates or severity of MI (P=0.254). In addition, no significant associations were observed between VDR polymorphisms and MI phenotypes (P=0.460). However, the results of the casewise multiple regression analysis indicated that the ApaI genotypes accounted for 18% of injury severity (P=0.002). Therefore, while the BsmI and FokI polymorphisms did not appear to be associated with the severity or incidence of MI, the ApaI genotypes may have influenced the severity of muscle injury in top-level football players.

Fedor, Andrew; Gunstad, John

2016-01-01

An estimated 1.6 million to 3.8 million sports-related concussions occur each year in the United States, and many are related to football. This has generated much discussion in the media on the perceived safety of the sport. In the current study, researchers asked 230 individuals various questions about attitudes toward safety in football. Approximately 92.6% of participants indicated they would allow their child to play football; these participants were more likely to be female (χ(2) = 5.23, p > .05), were slightly younger (t= -2.52, p < .05), and believed an athlete could suffer a higher number of concussions before becoming excessive (t = 2.06, p < .05). Findings suggest most individuals are comfortable with their children playing football, and future studies are needed to clarify factors that inform this opinion.

Introduction Little is known about Canadian youth football injuries. The objectives of this study were (a) to contrast the injuries in Canadian and American football players aged 6 to 17 years and (b) compare the injuries sustained during organized football with those in nonorganized football. Methods Using a retrospective cohort design based on data from the Canadian Hospitals Injury Reporting and Prevention Program and the National Electronic Injury Surveillance System a comparison of injuries was made. Results Trends in injuries were comparable. Proportions and odds of injuries were similar, except for a few exceptions. In Canada, more girls were injured and fractures were more prevalent. Compared with nonorganized football, organized football players were older, involved more males, and suffered more traumatic brain injuries and injuries to their lower extremities. Conclusion Canadian and American youth football injuries were similar. The type of football, be it organized or nonorganized, has an impact on injuries. © The Author(s) 2015.

This study examines whether negative social contextual stressors were associated with somatic symptoms among young Black males (N = 74) after accounting for background and psychological characteristics. Using Cunningham and Spencer’s Black Male Experiences Measure, negative social contextual stressors connoted those experiences connected to the personal attributes, devaluation, and negative imagery of young Black males, such as being followed when entering a store or police or security guards asking them what they are doing when hanging out (e.g., in the park or playground or on the street corner). Results showed that such stressors made a unique and significant contribution to the experience of somatic symptoms. Future research directions and implications for addressing the larger societal perceptions of young Black males are discussed. PMID:27134517

Football (soccer) is one of the most popular sports in the world, including Europe. It is associated with important betting activities. A common belief, widely spread among those who participate in gambling activities, is that knowledge and expertise on football lead to better prediction skills for match outcomes. If unfounded, however, this belief should be considered as a form of "illusion of control." The aim of this study was to examine whether football experts are better than nonexperts at predicting football match scores. Two hundred and fifty-eight persons took part in the study: 21.3% as football experts, 54.3% as laypersons (non-initiated to football), and 24.4% as football amateurs. They predicted the scores of the first 10 matches of the 2008 UEFA European Football Championship. Logistic regressions were carried out to assess the link between the accuracy of the forecasted scores and the expertise of the participants (expert, amateur, layperson), controlling for age and gender. The variables assessed did not predict the accuracy of scoring prognosis (R2 ranged from 1% to 6%). Expertise, age, and gender did not appear to have an impact on the accuracy of the football match prognoses. Therefore, the belief that football expertise improves betting skills is no more than a cognitive distortion called the "illusion of control." Gamblers may benefit from psychological interventions that target the illusion of control related to their believed links between betting skills and football expertise. Public health policies may need to consider the phenomenon in order to prevent problem gambling related to football betting.

To examine the mechanisms of injury for concussions in university football, ice hockey, and soccer. Prospective cohort design. McGill University Sport Medicine Clinic. Male and female athletes participating in varsity football, ice hockey, and soccer. Athletes were followed prospectively over a 10-year period to determine the mechanisms of injury for concussions and whether contact with certain areas of the body or individual variables predisposed to longer recovery from concussions. For soccer, data were collected on whether concussions occurred while attempting to head the ball. There were 226 concussions in 170 athletes over the study period. The side/temporal area of the head or helmet was the most common area to be struck resulting in concussion in all 3 sports. Contact from another player's head or helmet was the most probable mechanism in football and soccer. In hockey, concussion impacts were more likely to occur from contact with another body part or object rather than another head/helmet. Differences in mechanisms of injuries were found between males and females in soccer and ice hockey. Athletes with multiple concussions took longer to return to play with each subsequent concussion. Half of the concussions in soccer were related to attempting to head the soccer ball. The side of the head or helmet was the most common area to be struck resulting in concussion in all 3 sports. In ice hockey and soccer, there are differences in the mechanisms of injury for males and females within the same sport.

To study the psycho-social risk factors of sexual failure among newly married young males in the Uyghur population. We conducted a paired case control study of 186 newly married Uyghur young males (aged 17－30 ［23.4±2.9］ yr) with sexual failure and another 186 (aged 18－34 ［24.0±3.1］ yr) with no such problem as controls. We performed a logistic regression analysis on the possible psycho-social risk factors of this condition. Logistic regression analysis showed that the risk factors of sexual failure among the newly married men included personality (OR=0.271, 95% CI 0.176－0.420), income (OR=0.391, 95% CI 0.264－0.580), history of masturbation (OR=0.824, 95% CI 0.710－0.956), premarital sex (OR=0.757, 95% CI 0.677－0.847), sense of obligation (OR=1.756, 95% CI 1.157－2.693), equality of the social status (OR=0.574, 95% CI 0.435－0.756), degree of mutual care (OR=1.605, 95% CI 1.268－2.032), female's psychological obstacle (OR=2.832, 95% CI 1.221－6.569), and religion (OR=0.643, 95% CI 0.472－0.967). There was a statistical significance in the correlation between these factors and sexual failure in the newly married males (all P<0.05). Sexual failure of newly married Uyghur young males are associated with many psycho-social factors, which necessitates sexual education among young males and particularly pre-marriage sexual education and psychological guide among both males and females.

Motivational predictors of prosocial and antisocial behaviour in football.

PubMed

Kavussanu, Maria

2006-06-01

This study examined (a) the main and interactive effects of goal orientations and perceived motivational climate on prosocial and antisocial behaviour, and (b) whether number of seasons one has played for the team interacts with motivational climate in predicting prosocial and antisocial behaviour in association football. Participants were 325 male association football players, whose age ranged from 12 to 17 years. Athletes completed questionnaires measuring frequency of prosocial and antisocial behaviours in football, goal orientation, motivational climate and social desirability, and indicated the number of seasons they had played for their current team. Regression analyses revealed that task orientation and mastery climate were positive predictors of prosocial behaviour, whereas ego orientation and performance climate were positive predictors of antisocial behaviour. In addition, task orientation negatively predicted antisocial behaviour, while ego orientation negatively predicted prosocial behaviour. No significant interactions between task and ego orientation and mastery and performance motivational climate were found. Finally, mastery climate negatively predicted antisocial behaviour for those who had played many seasons for the team. In conclusion, strengthening task orientation and mastery climate and weakening ego orientation may enhance prosocial behaviour. However, for antisocial conduct to be eliminated from the context of association football, ego orientation and performance climate need to be tempered, as these constructs exert unique independent effects on antisocial behaviour.

Meta-analytical review on football heading effects on neurocognitive performance, cognition and symptom reports. Combinations of the key terms were entered into the following electronic database search engines: Cochrane Libraries, PyscARTICLE, PyscINFO, PubMed, ProQuest, SPORTDiscus and Web of Science on 7 July 2016. The following inclusion criteria were used to determine eligibility for studies: (1) the study examined and reported on soccer athletes; (2) the population's age, sex and sport position was described; (3) cognitive function, symptoms, balance or other outcomes were quantitatively measured; (4) football heading exposure was quantitatively measured between at least two groups and (5) the study was written in the English language after December 1979. The literature search process identified 467 unique studies. After applying exclusion criteria, 28 studies remained. Included studies had a total of 2288 participants (female participants =933, male participants =1355), aged 13-70 years. The overall results of random effects modelling of football heading were found to be inconclusive across all outcomes, groups and time points. No moderating variables related to methodological, sample or study characteristics were supported in the analysis; age was a potential moderating variable. We provide the first meta-analytical review of football heading effects aggregated from multiple studies and extended findings from a recent systematic review of the effects of football heading.

2014-01-01

Pancreatic injury is uncommon, accounting for less than 7% of penetrating and 5% of blunt abdominal trauma. Blunt isolated pancreatic trauma in football has been rarely described in the literature and its diagnosis, detection and treatment still remains a challenge. We report a case of a young adult with an isolated complete rupture of the pancreatic body due to a blunt abdominal trauma during a football game. In order to preserve the pancreas and therefore retain function, we performed a terminolateral pancreaticojejunostomy. The postoperative course of the patient was uneventful. The diagnosis of isolated injuries of the pancreas in blunt abdominal trauma can be difficult and challenging and due to the nature of the game physicians should be highly alerted when dealing with football players sustaining abdominal trauma.

Although the incidence of football injuries should relate to team success there is little empirical evidence. We investigated the relationship between injury incidence and team success in Qatar first-division football clubs. Using a prospective cohort study design, we captured exposure and injuries in Qatar male elite football for a season. Club performance was measured by total league points, ranking, goal scored, goals conceded and number of matches won, drawn or lost. Lower injury incidence was strongly correlated with team ranking position (r=0.929, p=0.003), more games won (r=0.883, p=0.008), more goals scored (r=0.893, p=0.007), greater goal difference (r=0.821, p=0.003) and total points (r=0.929, p=0.003). Lower incidence rate was strongly correlated with team success. Prevention of injuries may contribute to team success.

Age determination on magnetic resonance imaging (MRI) of the wrist is a reliable method in male football players to evaluate their eligibility to participate in Under 17 tournaments. MRI of the wrist was performed in 487 female volunteers aged 13-19 years from Brazil, Germany, Malaysia, and Tanzania, and in 139 female football players participating in Under-16 and Under-17 football tournaments. A previously validated method for grading fusion of the distal radial epiphysis in male adolescent was used. Moderate correlation of chronological age and epiphyseal fusion was found in the normative control group (r = .59) and weak correlation in female football players (r = .27). Complete fusion of the distal radial epiphysis was observed in two 15-year-old volunteers of the control group (1.7%) and in 17.6% (3 of 17) of 14-year-old football players. Up to 10.8% (47 of 437) in the control group and 14.4% (20 of 139) of the football players 17 years or younger had complete fused epiphysis. Because of earlier osseous maturity in female adolescents, the grade of fusion of the distal radial epiphysis on MRI is not recommended for pretournament age determination for the age of 17 and younger in female. © 2015 John Wiley & Sons A/S.

Rizzone, Katie; Diamond, Alex; Gregory, Andrew

2013-01-01

Youth football is a popular sport in the United States and has been for some time. There are currently more than 3 million participants in youth football leagues according to USA Football. While the number of participants and overall injuries may be higher in other sports, football has a higher rate of injuries. Most youth sporting events do not have medical personnel on the sidelines in event of an injury or emergency. Therefore it is necessary for youth sports coaches to undergo basic medical training in order to effectively act in these situations. In addition, an argument could be made that appropriate medical personnel should be on the sideline for collision sports at all levels, from youth to professional. This article will discuss issues pertinent to sideline coverage of youth football, including coaching education, sideline personnel, emergency action plans, age and size divisions, tackle versus flag football, and injury prevention.

To know the influence of televised football on the use of emergency department (ED). We assessed the number, demographic characteristics and acuity of patients attended during the broadcast of football matches played by FC Barcelona during Champions' League (n = 12), and they were compared with days without televised football (n = 12). Televised football was associated with a decrease in visits to ED (-18%; p = 0.002). Such a decrease was observed for all ED units, but only for traumatology unit reached statistical significance (-28%; p = 0.006). Decay of ED visits were mainly due to a decrease of low-acuity consults (-30%; p = 0.04). There is a significant decrease on ED use associated with televised football.

The purpose of this study was to investigate the influence of perceived motivational climate and gender on sportspersonship behavior of competitive youth football players. Participants were 512 boy and 202 girl Norwegian youth football players (12-14 years old) competing in an international football tournament. A 2 x 2 x 2 (gender, mastery climate high and low, performance climate high and low) MANOVA produced no multivariate or interaction effects, but main effects for gender, performance climate, and mastery climate did emerge. Post hoc analyses of the simple main effects found that boys and girls were different in sportspersonship, but only in that boys were more sportspersonlike than girls on one of the four sportspersonship dimensions. Players perceiving a high mastery climate endorsed sportspersonship more than those players perceiving a low mastery climate, and players perceiving a high performance climate were less likely to endorse sportspersonship than players perceiving a low performance climate. Canonical correlation analysis revealed that a strong mastery climate was positively associated with commitment, respect for social conventions, and respect for rules and officials. A strong performance climate was negatively associated with respect and concern for social conventions and respect for rules and officials, while a positive association emerged for respect and concern for the opponent. The results of our study suggest that both boys and girls may well perceive the coach emphasizing similar criteria of success and failure and thereby a similar culture of sportspersonship, while in general a strong mastery climate leads to a higher sportspersonship orientation.

Imaging of American football injuries in children.

It is estimated that 3.2 million children ages 6 to 14 years participated in organized youth football in the United States in 2007. Approximately 240,000 children play football in the nation's largest youth football organization, with tackle divisions starting at age 5 years. The number of children playing unsupervised football is much higher, and the overall number of children participating in American football is increasing. Sports are the leading cause of injury-related emergency room visits for teenagers, and football is a leading precipitating athletic activity for these visits. Football is also the most hazardous organized sports in the United States. Though most pediatric football-related injuries are minor, such as abrasions, sprains, and strains of the extremities, football accounts for more major and catastrophic injuries than any other sport. Given football's popularity with children in the United States, combined with the high rate of injury associated with participation in this activity, radiologists should be familiar with the imaging features and injury patterns seen in this patient population.

Australian rural football club leaders as mental health advocates: an investigation of the impact of the Coach the Coach project

PubMed Central

2010-01-01

Background Mental ill health, especially depression, is recognised as an important health concern, potentially with greater impact in rural communities. This paper reports on a project, Coach the Coach, in which Australian rural football clubs were the setting and football coaches the leaders in providing greater mental health awareness and capacity to support early help seeking behaviour among young males experiencing mental health difficulties, especially depression. Coaches and other football club leaders were provided with Mental Health First Aid (MHFA) training. Method Pre-post measures of the ability of those club leaders undertaking mental health training to recognise depression and schizophrenia and of their knowledge of evidence supported treatment options, and confidence in responding to mental health difficulties were obtained using a questionnaire. This was supplemented by focus group interviews. Pre-post questionnaire data from players in participating football clubs was used to investigate attitudes to depression, treatment options and ability to recognise depression from a clinical scenario. Key project stakeholders were also interviewed. Results Club leaders (n = 36) who were trained in MHFA and club players (n = 275) who were not trained, participated in this evaluation. More than 50% of club leaders who undertook the training showed increased capacity to recognise mental illness and 66% reported increased confidence to respond to mental health difficulties in others. They reported that this training built upon their existing skills, fulfilled their perceived social responsibilities and empowered them. Indirect benefit to club players from this approach seemed limited as minimal changes in attitudes were reported by players. Key stakeholders regarded the project as valuable. Conclusions Rural football clubs appear to be appropriate social structures to promote rural mental health awareness. Club leaders, including many coaches, benefit from MHFA

Third molar observations in a sample of British male young offenders.

PubMed

Andrews, Sally E

2015-07-01

Development, morphology and eruption of third molars are highly variable, and it is generally accepted that the emergence time is between the ages of 17 and 21 years. This study reports on variation in timing encountered in a sample of 155 young males (15-18 years) of British nationality who were detained at Her Majesty's Prison and Young Offenders Institution (HMP&YOI) Ashfield as young offenders. All 155 participants were self-reported in terms of their chronological age and their ethnic origin. Of the 17 year-olds, 68% of Black males displayed one or more erupted third molars compared to 39% of the White males. For those who were of mixed ancestry, 50% showed evidence of eruption of at least one third molar in this age group. This difference between Black and White ethnicity was further supported when missing first or second molars were taken into consideration. Whilst it has been suggested in the literature that ethnicity plays no major part in eruption timings for the third molars, this clinical observation poses some interesting questions about the accuracy of dental age assessment.

2013-01-01

The purpose of the study was to evaluate ECG abnormalities in a large sample of elite football players. Data from 566 elite male football players (57 of them of African origin) above 16 years of age were screened retrospectively (age: 20.9 ± 5.3 years; BMI: 22.9 ± 1.7 kg · m(-2), training history: 13.8 ± 4.7 years). The resting ECGs were analysed and classified according to the most current ECG categorisation of the European Society of Cardiology (ESC) (2010) and a classification of Pelliccia et al. (2000) in order to assess the impact of the new ESC-approach. According to the classification of Pelliccia, 52.5% showed mildly abnormal ECG patterns and 12% were classified as distinctly abnormal ECG patterns. According to the classification of the ESC, 33.7% showed 'uncommon ECG patterns'. Short-QT interval was the most frequent ECG pattern in this group (41.9%), followed by a shortened PR-interval (19.9%). When assessed with a QTc cut-off-point of 340 ms (instead of 360 ms), only 22.2% would have had 'uncommon ECG patterns'. Resting ECG changes amongst elite football players are common. Adjustment of the ESC criteria by adapting proposed time limits for the ECG (e.g. QTc, PR) should further reduce the rate of false-positive results.

The toll of the gridiron: damage-associated molecular patterns and hypertension in American football

PubMed Central

McCarthy, Cameron G.; Webb, R. Clinton

2016-01-01

American football has unequivocally been linked to elevations in blood pressure and hypertension, especially in linemen. However, the mechanisms of this increase cannot be attributed solely to increased body weight and associated cardiometabolic risk factors (e.g.,dyslipidemia or hyperglycemia). Therefore, understanding the etiology of football-associated hypertension is essential for improving the quality of life in this mostly young population, as well as for lowering the potential for chronic disease in the future. We propose that inflammatogenic damage–associated molecular patterns (DAMPs) released into the circulation from football-induced musculoskeletal trauma activate pattern-recognition receptors of the innate immune system—specifically, high mobility group box 1 protein (HMGB1) and mitochondrial (mt)DNA which activate Toll-like receptor (TLR)4 and -9, respectively. Previously, we observed that circulating levels of these 2 DAMPs are increased in hypertension, and activation of TLR4 and -9 causes endothelial dysfunction and hypertension. Therefore, our novel hypothesis is that musculoskeletal injury from repeated hits in football players, particularly in linemen, leads to elevated circulating HMGB1 and mtDNA to activate TLRs on endothelial cells leading to impaired endothelium-dependent vasodilation, increased vascular tone, and hypertension.—McCarthy, C. G., Webb, R. C. The toll of the gridiron: damage-associated molecular patterns and hypertension in American football. PMID:26316270

Thinner Cortex in Collegiate Football Players With, but not Without, a Self-Reported History of Concussion.

Emerging evidence suggests that a history of sports-related concussions can lead to long-term neuroanatomical changes. The extent to which similar changes are present in young athletes is undetermined at this time. Here, we tested the hypothesis that collegiate football athletes with (n = 25) and without (n = 24) a self-reported history of concussion would have cortical thickness differences and altered white matter integrity relative to healthy controls (n = 27) in fronto-temporal regions that appear particularly susceptible to traumatic brain injury. Freesurfer software was used to estimate cortical thickness, fractional anisotropy was calculated in a priori white matter tracts, and behavior was assessed using a concussion behavioral battery. Groups did not differ in self-reported symptoms (p > 0.10) or cognitive performance (p > 0.10). Healthy controls reported significantly higher happiness levels than both football groups (all p < 0.01). Contrary to our hypothesis, no differences in fractional anisotropy were observed between our groups (p > 0.10). However, football athletes with a history of concussion had significantly thinner cortex in the left anterior cingulate cortex, orbital frontal cortex, and medial superior frontal cortex relative to healthy controls (p = 0.02, d = -0.69). Further, football athletes with a history of concussion had significantly thinner cortex in the right central sulcus and precentral gyrus relative to football athletes without a history of concussion (p = 0.03, d = -0.71). No differences were observed between football athletes without a history of concussion and healthy controls. These results suggest that previous concussions, but not necessarily football exposure, may be associated with cortical thickness differences in collegiate football athletes.

Clinically-measured vision did not differ according to officiating level. Visual acuity measured with and without a pinhole disc indicated that around one quarter of participants may be capable of better vision when officiating, as evidenced by better acuity (≥1 line of letters) using the pinhole. Amongst the clinical visual tests we used, we did not find evidence for above-average performance in elite-level football officials. Although the impact of uncorrected mild to moderate refractive error upon officiating performance is unknown, with a greater uptake of eye examinations, visual acuity may be improved in around a quarter of officials.

Amenabar, Tomas; O'Donnell, John

2013-07-01

To study the return to sport in a series of professional athletes in a single sport (Australian Rules Football), operated on arthroscopically for hip joint pathology. We performed a retrospective review of the senior author's surgical database starting in 2003. All of the patients who were Australian Football League (AFL) professional players with a minimum of 2 years' follow-up were included. Intra-articular pathologies were identified and treated. All patients were prospectively assessed with the modified Harris Hip Score (MHHS) and the Non-Arthritic Hip Score (NAHS). In addition, information about the active participation of the patients in their teams and return to professional sport was obtained from AFL registers and team physicians. Since 2003, the senior author has operated on 36 male professional AFL players; 26 of 27 with at least 2 years' follow-up were available for review. The mean age at the time of surgery was 22.1 years (range, 16 to 30 years), and 8 patients had bilateral pathology; therefore 34 hips were operated on. This report refers to those 26 players and 34 hips. All but 1 of the patients returned to play professionally. By the last survey (October 2011), 16 patients (62%) were still playing professional AFL football, and they have been playing for a mean of 52.5 months after surgery. Ten patients had retired from professional football, but they had all returned to play professionally after surgery. Only one of them retired for causes related to hip disability. There was a significant improvement in preoperative outcome scores. The MHHS and NAHS improved from 83.6 to 98 and from 85.3 to 97.1, respectively, in the players who were still playing (P < .05). Rim lesions were present in 33 hips (97%). Femoral osteochondroplasty was performed in 26 hips (76%). Arthroscopic treatment of intra-articular pathologies in professional athletes resulted in a 96% rate of return to elite-level sport and a durable increase in the MHHS and NAHS. Level IV

Background Data on the incidence, nature, severity and cause of match football injuries sustained on dirt field are scarce. The objectives of this study was to compare the incidence, nature, severity and cause of match injuries sustained on dirt field and artificial turf field by amateur male football players. Methods A prospective two-cohort design was employed. Participants were 252 male football players (mean age 27 years, range 18-43) in 14 teams who participated in a local championship carried on a dirt field and 216 male football players (mean age 28 years, range 17-40) in 12 teams who participated in a local championship carried on a artificial turf field in the same zone of the city. Injury definitions and recording procedures were compliant with the international consensus statement for epidemiological studies of injuries in football. Results The overall incidence of match injuries for men was 36.9 injuries/1000 player hours on dirt field and 19.5 on artificial turf (incidence rate ratio 1.88; 95% CI 1.19-3.05). Most common injured part on dirt field was ankle (26.7%) and on artificial turf was knee (24.3%). The most common injury type in the dirt field was skin injuries (abrasion and laceration) and in the artificial turf was sprain and ligament injury followed by haematoma/contusion/bruise. Most injuries were acute (artificial turf 89%, dirt field 91%) and resulted from player-to-player contact (artificial turf 59.2%, dirt field 51.4%). Most injuries were slight and minimal in dirt field cohort but in artificial turf cohort the most injuries were mild. Conclusions There were differences in the incidence and type of football match injuries sustained on dirt field and artificial turf. PMID:21306640

The aim of this study was to investigate the association between MCT1 rs1049434 polymorphism and indirect muscle injuries in elite football players. One hundred and seventy-three male elite Italian football players (age = 19.2 ± 5.3 years) were recruited from a first-league football club participating at the Official National Italian Football Championship (Serie A, Primavera, Allievi, Giovanissimi). The cohort was genotyped for the MCT1 rs1049434 polymorphism, and muscle injuries data were collected during the period of 2009-2014 (five football seasons). Genomic DNA was extracted using a buccal swab, and genotyping was performed using PCR method. Structural-mechanical injuries and functional muscle disorder were included in the acute indirect muscle injury group. Participants with the MCT1 AA (AA = 1.57 ± 3.07, n  = 69) genotype exhibit significantly higher injury incidents compared to participants with the TT genotype (TT = 0.09 ± 0.25, n  = 22, P  = 0.04). The MCT1 rs1049434 polymorphism is associated with the incidence of muscle injuries in elite football players. We anticipate that the knowledge of athletes' genetic predisposition to sports-related injuries might aid in individualizing training programs.

In American football, pass interference calls can be difficult to make, especially when the timing of contact between players is ambiguous. American football history contains many examples of controversial pass interference decisions, often with fans, players, and officials interpreting the same event differently. The current study sought to evaluate the influence of experience with concepts important for officiating decisions in American football on the probability (i.e., response criteria) of pass interference calls. We further investigated the extent to which such experience modulates perceptual biases that might influence the interpretation of such events. We hypothesized that observers with less experience with the American football concepts important for pass interference would make progressively more pass interference calls than more experienced observers, even when given an explicit description of the necessary criteria for a pass interference call. In a go/no-go experiment using photographs from American football games, three groups of participants with different levels of experience with American football (Football Naïve, Football Player, and Football Official) made pass interference calls for pictures depicting left-moving and right-moving events. More experience was associated with progressively and significantly fewer pass interference calls [F(2,48) = 10.4, p < 0.001], with Football Naïve participants making the most pass interference calls, and Football Officials the least. In addition, our data replicated a prior finding of spatial biases for interpreting left-moving images more harshly than identical right-moving images, but only in Football Players. These data suggest that experience with the concepts important for making a decision may influence the rate of decision-making, and may also play a role in susceptibility to spatial biases.

To review the available football epidemiology literature to identify risk factors, facilitate injury prevention and uncover deficiencies that may be addressed by future research. A literature search of Sports Discus (1940-2003), Eric (1967-2003), EMBASE (1988-2003), MEDLINE (1966-2003), CINAHL (1984-2003), and Web of Science (1993-2003) identified the published articles on American football in athletes of high school age and younger. Injury rate increases with the level of play (grade in school), player age, and player experience. The lower extremity (knee and ankle joints) is most frequently injured. Football injuries are much more common in games than in practice, and occur to players who are being tackled, tackling or blocking. Most injuries are mild, including contusion, strain and sprain. Rule changes with the prohibition of initial contact with the helmet or face-mask reduced catastrophic head and neck injuries. Although no sport or recreational activity is completely risk-free, football epidemiology research is critical to injury prevention. The existing medical literature provides some valuable insights, but an increased emphasis on prospective research is required to test the efficacy of preventative measures. Quality research may contribute to a reduction in football injury risk by defining the role of player conditioning and strength training, coaching of safety fundamentals, avoidance of dangerous activities, as well as proper medical supervision and care. Sports medicine personnel, coaches, and officials must strive to minimize injuries through progressive education, improved coaching techniques, effective officiating, and equipment modifications.

Background: There are approximately 2.8 million youth football players between the ages of 7 and 14 years in the United States. Rates of injury in this population are poorly described. Recent studies have reported injury rates between 2.3% and 30.4% per season and between 8.5 and 43 per 1000 exposures. Hypothesis: Youth flag football has a lower injury rate than youth tackle football. The concussion rates in flag football are lower than in tackle football. Study Design: Cohort study; Level of evidence, 3. Methods: Three large youth (grades 2-7) football leagues with a total of 3794 players were enrolled. Research personnel partnered with the leagues to provide electronic attendance and injury reporting systems. Researchers had access to deidentified player data and injury information. Injury rates for both the tackle and flag leagues were calculated and compared using Poisson regression with a log link. The probability an injury was severe and an injury resulted in a concussion were modeled using logistic regression. For these 2 responses, best subset model selection was performed, and the model with the minimum Akaike information criterion value was chosen as best. Kaplan-Meier curves were examined to compare time loss due to injury for various subgroups of the population. Finally, time loss was modeled using Cox proportional hazards regression models. Results: A total of 46,416 exposures and 128 injuries were reported. The mean age at injury was 10.64 years. The hazard ratio for tackle football (compared with flag football) was 0.45 (95% CI, 0.25-0.80; P = .0065). The rate of severe injuries per exposure for tackle football was 1.1 (95% CI, 0.33-3.4; P = .93) times that of the flag league. The rate for concussions in tackle football per exposure was 0.51 (95% CI, 0.16-1.7; P = .27) times that of the flag league. Conclusion: Injury is more likely to occur in youth flag football than in youth tackle football. Severe injuries and concussions were not significantly

Determine if balance and technique training implemented adjunct to 1001 male Australian football players' training influenced the activation/strength of the muscles crossing the knee during pre-planned and unplanned sidestepping. Randomized Control Trial. Each Australian football player participated in either 28 weeks of balance and technique training or 'sham' training. Twenty-eight Australian football players (balance and technique training, n=12; 'sham' training, n=16) completed biomechanical testing pre-to-post training. Peak knee moments and directed co-contraction ratios in three degrees of freedom, as well as total muscle activation were calculated during pre-planned and unplanned sidestepping. No significant differences in muscle activation/strength were observed between the 'sham' training and balance and technique training groups. Following a season of Australian football, knee extensor (p=0.023) and semimembranosus (p=0.006) muscle activation increased during both pre-planned sidestepping and unplanned sidestepping. Following a season of Australian football, total muscle activation was 30% lower and peak valgus knee moments 80% greater (p=0.022) during unplanned sidestepping when compared with pre-planned sidestepping. When implemented in a community level training environment, balance and technique training was not effective in changing the activation of the muscles crossing the knee during sidestepping. Following a season of Australian football, players are better able to support both frontal and sagittal plane knee moments. When compared to pre-planned sidestepping, Australian football players may be at increased risk of anterior cruciate ligament injury during unplanned sidestepping in the latter half of an Australian football season.

Background There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. Purpose To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions. Study Design Cross-sectional study; Level of evidence, 3. Methods Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. Results There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines). Conclusion In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting. PMID:27474382

Healthy controls reported significantly higher happiness levels than both football groups (all p < 0.01). Contrary to our hypothesis, no differences in fractional anisotropy were observed between our groups (p > 0.10). However, football athletes with a history of concussion had significantly thinner cortex in the left anterior cingulate cortex, orbital frontal cortex, and medial superior frontal cortex relative to healthy controls (p = 0.02, d = −0.69). Further, football athletes with a history of concussion had significantly thinner cortex in the right central sulcus and precentral gyrus relative to football athletes without a history of concussion (p = 0.03, d = −0.71). No differences were observed between football athletes without a history of concussion and healthy controls. These results suggest that previous concussions, but not necessarily football exposure, may be associated with cortical thickness differences in collegiate football athletes. PMID:26061068

Energy drinks are predominantly targeted to young adult consumers; however, there has been limited research into their effects on psychological functioning in this demographic group. This study examined cross-sectional associations between energy drink consumption and mental health in a population-based sample of young adults participating in the Western Australian Pregnancy Cohort (Raine) Study. We used self-report questionnaires to assess energy drink consumption and mental health (Depression Anxiety Stress Scale-21; DASS-21) at the 20-year cohort follow-up. In the regression analyses, we considered associations between energy drink consumption (mL/day) and continuous DASS-21 scores, adjusting for sociodemographic variables, alcohol and drug use, physical activity, body mass index (BMI), and dietary intake. Our sample included 502 males and 567 females (mean age 20 ± 3 years). After adjusting for potential confounding factors and controlling for coexisting mental health problems, energy drink consumption (per 100 mL/day) was significantly associated with anxiety (but not depression or stress), and this relationship was found only in males (β = 0.32; 95% CI = 0.05, 0.58). Our study found that energy drink consumption was associated with increased anxiety in young adult males. Further research into the possible contribution of energy drink use to the development of mental health problems in young adults is needed. © 2013 Wiley Periodicals, Inc.

To assess the effectiveness of a standard long-handle laryngoscope and a short-handle laryngoscope on ease of possible intubation in football, ice hockey, and soccer players. Prospective crossover study. University Sport Medicine Clinic. Sixty-two university varsity football (62 males), 45 ice hockey (26 males and 19 females), and 39 soccer players (20 males, 19 females). Athletes were assessed for different airway and physical characteristics. Three different physicians then assessed the use of laryngoscopes of different handle sizes in supine athletes who were wearing protective equipment while in-line cervical spine immobilization was maintained. The ease of passage of a laryngoscope blade into the posterior oropharynx of a supine athlete was assessed using both a standard long-handle and a short-handle laryngoscope. Use of a short-handle laryngoscope was easier for all physicians in all sports as compared with a standard-sized laryngoscope. Passage of a laryngoscope blade into the posterior oropharynx of a supine athlete was easiest in soccer players and most difficult in football and ice hockey players for both sizes of laryngoscope. Interference from chest or shoulder pads was a common cause for difficulty in passing the laryngoscope blade into the posterior oropharynx for football and ice hockey players. In the rare instances that an endotracheal intubation is to be attempted on an unconscious athlete, a short-handle laryngoscope may provide the best chance for successful intubation.

Sufficient first aid equipment is essential to treat injuries on football fields. Deficits in first aid on field are still present in youth football. Injury pattern in youth football over one season and first aid equipment in youth football were analyzed, retrospectively. PRICE and ABC procedure served as basic principles in emergency management to assess the need for first aid equipment on field. Considering financial limits and adapted on youth football injuries, sufficient first aid equipment for youth football was configured. 84% of 73 participating youth football teams had their own first aid kit, but the majority of them were insufficiently equipped. Team coaches were in 60% of all youth teams responsible for using first aid equipment. The injury evaluation presented 922 injuries to 1,778 youth players over one season. Frequently presented types of injury were contusions and sprains of the lower extremity. Based on the analyzed injury data in youth football, first aid equipment with 90 € is sufficient for 100% of all occurred youth football injuries. Current first aid equipment in youth football is insufficient. Scientific-based first aid equipment with 90 € is adequate to serve all injuries. Football coaches need education in first aid management.

The objective of this study was to assess the overall health, including sexual and reproductive health (SRH) knowledge and needs, sexual behaviors, and testicular health practices among young minority males. Anonymous questionnaires were administered to 18- to 25-year-old males receiving services at health clinics in a large southwestern U.S. city. The survey was completed by 258 males with a mean age of 20.8 years. Most young males (67.1%) identified as African American, and 32.9% as Hispanic. Results suggest study participants lack SRH knowledge related to pregnancy and condom effectiveness, and engage in risky sexual behavior including not using birth control at their last sexual encounter. Although 21.6% of participants had a sexually transmitted infection (STI) in the past year, approximately 80% perceived their STI/HIV risk as very low or low. Respondents had low engagement and lack of knowledge of testicular health practices. The majority of respondents (71.1%) reported having been in a physical fight one or more times and 18.1% reported being victims of intimate partner violence. These data support a need for comprehensive health services for minority young males.

Factors associated with playing football after anterior cruciate ligament reconstruction in female football players.

2016-11-01

This study investigated whether player-related factors (demographic, personality, or psychological factors) or the characteristics of the anterior cruciate ligament (ACL) injury were associated with the return to playing football in females after ACL reconstruction (ACLR). We also compared current knee function, knee related quality of life and readiness to return to sport between females who returned to football and those who had not returned. Females who sustained a primary ACL rupture while playing football and underwent ACLR 6-36 months ago were eligible. Of the 460 contacted, 274 (60%) completed a battery of questionnaires, and 182 were included a median of 18 months (IQR 13) after ACLR. Of these, 94 (52%) returned to football and were currently playing, and 88 (48%) had not returned. Multiple logistic regression analysis identified two factors associated with returning to football: short time between injury and ACLR (0-3 months, OR 5.6; 3-12 months OR 4.7 vs reference group > 12 months) and high motivation. Current players showed higher ratings for current knee function, knee-related quality of life, and psychological readiness to return to sport (P < 0.001). Undergoing ACLR sooner after injury and high motivation to return to sports may impact a player's return to football after ACLR. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Online news media reporting of football-related fatalities in Australia: A matter of life and death.

Fortington, Lauren V; Bekker, Sheree; Finch, Caroline F

2018-03-01

While deaths in sports settings are rare, they do occur. To develop an understanding of the sports and people most at risk, and to identify opportunities for prevention, routine and systematic data detailing the occurrence of these fatalities is required. There is currently no routine reporting of data of this nature in Australia. As there is often strong community interest in these incidents, the media offers an opportunity for surveillance. However before this can occur, understanding of the terminology used by the media is required. The aim of this study was to identify the terminology most frequently used in online Australian news media coverage of football-related deaths. Retrospective review of online news media. Three databases were searched for online news media reports of people who died while participating in football (all football codes) in Australia. A descriptive analysis of terminology was undertaken to identify the common language applied. Thirty-four football-related fatalities in Australia were identified between 2010-2016, via 149 separate articles. The most frequent terms identified in the media items were: Family; Club; Rugby; Football; Player; League; Died; Game; Death; Life; Loved; Hospital; Match; Young; Community; Playing; Friends; Sport; Heart; AFL [Australian Football League]. This study identified terminology used in reporting football-related fatalities in Australia, identifying common reference to terms relating to 'death' as metaphors and the frequent celebration of 'life.' The findings suggest that a reliance on researcher-generated terminology will be insufficient to reflect media discourse in prospective monitoring of sports deaths for surveillance.

2016-01-01

The primary purpose of this study was to investigate the effect of the place of early development in a sample of Danish male elite and youth handball and football players. The sample included 366 handball and football players from the elite Danish league in the season 2011-2012 and a comparison sample of youth players under the age of 12 from 2003, including 147,221 football and 26,290 handball players. Odds ratio analysis showed that both population size and density significantly affected the proportional number of youth players per community and the odds of athletes reaching an elite level in football and handball. The odds for youth player registrations in both handball and football increased in rural in contrast to urban communities. However, elite football players primarily came from communities of high density (>1000 pop./km(2)), whereas elite handball players primarily came from less densely populated communities (100 to <250 pop./km(2)). Furthermore, there seems to be a relation between representation of elite and talent clubs in different communities and the probability of becoming an elite player in both sports. The limited number of elite players in both sports from rural communities may be due to national talent development strategies that do not incorporate development support for clubs in rural areas. Additionally, the results of the study clearly suggest the need to include the youth player population to advance research findings in birthplace effect studies.

To ascertain the epidemiology of ankle injuries in elite youth football. Retrospective analysis of prospectively collected injury data from English Football Association (FA) academies. Forty-one FA football academies, between 1998 and 2006. For the complete seasons studied, a total of 14 776 players was registered from U9 to the U16 age category, a mean of 2463 players per year. All ankle injuries of sufficient severity to miss 48 h or more of training were studied, 2563 injuries in total. The incidence and burden of ankle injuries in this population and factors associated with injury. There was a mean incidence of one ankle injury per player per year, and a mean of 20 training days and two matches were missed per ankle injury. Increased injury rates were seen in older players, in competition and later in each half of match time. Peaks in injury were observed early in the season and after the winter break. In competition, more injuries were associated with a contact situation than in training. Eighty-eight injuries (3.4%) required a lay-off of 3 months or more and in 18 (0.7%) cases the player failed to return to training. In total, 52 290 training days and 5182 match appearances were lost through ankle injury. The majority of injuries were sprains, but more severe injuries occurred accounted for 3.9% of the total. Ankle injuries are common in young football players and are often severe, with prolonged loss of training time. This has potential far-reaching implications, both on and off the field.

Cerebral concussion is common in collision sports such as football, yet the chronic neurological effects of recurrent concussion are not well understood. The purpose of our study was to investigate the association between previous head injury and the likelihood of developing mild cognitive impairment (MCI) and Alzheimer's disease in a unique group of retired professional football players with previous head injury exposure. A general health questionnaire was completed by 2552 retired professional football players with an average age of 53.8 (+/-13.4) years and an average professional football playing career of 6.6 (+/- 3.6) years. A second questionnaire focusing on memory and issues related to MCI was then completed by a subset of 758 retired professional football players (> or = 50 yr of age). Results on MCI were then cross-tabulated with results from the original health questionnaire for this subset of older retirees. Of the former players, 61% sustained at least one concussion during their professional football career, and 24% sustained three or more concussions. Statistical analysis of the data identified an association between recurrent concussion and clinically diagnosed MCI (chi = 7.82, df = 2, P = 0.02) and self-reported significant memory impairments (chi = 19.75, df = 2, P = 0.001). Retired players with three or more reported concussions had a fivefold prevalence of MCI diagnosis and a threefold prevalence of reported significant memory problems compared with retirees without a history of concussion. Although there was not an association between recurrent concussion and Alzheimer's disease, we observed an earlier onset of Alzheimer's disease in the retirees than in the general American male population. Our findings suggest that the onset of dementia-related syndromes may be initiated by repetitive cerebral concussions in professional football players.

A cross sectional study of functional movement in Gaelic games at Elite and Sub-Elite level. Players were video recorded completing the Functional Movement Screen Tool and scored post-test. Comparisons were analysed using Mann-Whitney U tests. Field testing in team gym facility and university biomechanics laboratory. A total of 62 players were tested. This consisted of 41 Hurling, and 21 Gaelic Football players. 30 of these participants were deemed Elite and 32 were deemed Sub-Elite. The mean age of the sample was 22.15 ± 3.02 years. Functional Movement Screen (FMS). The FMS mean score for the sample was 15.56 ± 1.46. The Elite group (15.8 ± 1.58) scored higher than the Sub-Elite group (15.34 ± 1.31) but there was no significant difference between groups. This study provides normative reference values for Gaelic Players. Elite Gaelic Players perform no better than a young, active population in the FMS indicating a potential problem with the FMS as a measure. Copyright © 2013 Elsevier Ltd. All rights reserved.

Older adults have been reported to have a lower evaporative heat loss capacity than younger adults during exercise when full sweat evaporation is permitted. However, it is unclear how conditions of restricted evaporative and convective heat loss (i.e., high humidity, clothing insulation) alter heat stress. to the purpose of this study was to examine the heat stress responses of young and older males during and following exercise in a warm/humid environment under two different levels of air velocity. Ten young (YOUNG: 24±2 yr) and 10 older (OLDER: 59±3 yr) males, matched for body surface area performed 4×15-min cycling bouts (15-min rest) at a fixed rate of heat production (400 W) in warm/humid conditions (35°C, 60% relative humidity) under 0.5 (Low) and 3.0 (High) m·s(-1) air velocity while wearing work coveralls. Rectal (Tre) and mean skin (MTsk) temperatures, heart rate (HR), local sweat rate, % max skin blood flow (SkBF) (recovery only), and blood pressure (recovery only) were measured. High air velocity reduced core and skin temperatures (p < 0.05) equally in YOUNG and OLDER males (p > 0.05) but was more effective in reducing cardiovascular strain (absolute and % max HR; p < 0.05) in YOUNG males (p < 0.05). Greater increases in local dry heat loss responses (% max SkBF and cutaneous vascular conductance) were detected across time in OLDER than YOUNG males in both conditions (p < 0.05). Local dry heat loss responses and cardiovascular strain were attenuated during the High condition in YOUNG compared to OLDER (p < 0.05). High air velocity reduced the number of males surpassing the 38.0°C Tre threshold from 90% (Low) to 50% (High). Despite age-related local heat loss differences, YOUNG and OLDER males had similar levels of heat stress during intermittent exercise in warm and humid conditions while wearing work coveralls. Increased air velocity was effective in reducing heat stress equally, and cardiovascular strain to a greater extent, in YOUNG and OLDER

The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors. Although cancer therapy is associated with many adverse effects, one of the primary concerns of young male cancer survivors is reproductive health. Future fertility is often the focus of concern; however, it must be recognized that all aspects of male health, including pubertal development, testosterone production, and sexual function, can be impaired by cancer therapy. Although pretreatment strategies to preserve reproductive health have been beneficial to some male patients, many survivors remain at risk for long-term reproductive complications. Understanding risk factors and monitoring the reproductive health of young male survivors are important aspects of follow-up care. The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer (COG-LTFU Guidelines) were created by the COG to provide recommendations for follow-up care of survivors at risk for long-term complications. The male health task force of the COG-LTFU Guidelines, composed of pediatric oncologists, endocrinologists, nurse practitioners, a urologist, and a radiation oncologist, is responsible for updating the COG-LTFU Guidelines every 2 years based on literature review and expert consensus. This review summarizes current task force recommendations for the assessment and management of male reproductive complications after treatment for childhood, adolescent, and young adult cancers. Issues related to male health that are being investigated, but currently not included in the COG-LTFU Guidelines, are also discussed. Ongoing investigation will inform future COG-LTFU Guideline recommendations for follow-up care to improve health and quality of life for male survivors. PMID:22649147

80 very young football players (from 8 to 12) have been examined for three months by some clinical and instrumental cardiologic tests (starting E.C.G. and after graduated stresses on a football court). The starting E.C.G. showed variable extresystolic arrhythmias in 8 subjects, without any sure signs of a cardiopathy, to point out by deeper tests (such as polygraphic, echocardiographic test and rx heart teleradiography). The above-mentioned arrhythmias felt the effects of training variably, since they regressed in 6 cases, however two subjects needed a pharmacological intervention. They are still talking over the meaning to give to extrasystolic arrhythmias in very young people in evaluation of attitude to agonism and in programming training.

Joint-position sense is altered by football pre-participation warm-up exercise and match induced fatigue.

2015-06-01

The demands to which football players are exposed during the match may augment the risk of injury by decreasing the sense of joint position. This study aimed to assess the effect of pre-participation warm-up and fatigue induced by an official football match on the knee-joint-position sense of football players. Fourteen semi-professional male football players (mean age: 25.9±4.6 years old) volunteered in this study. The main outcome measures were rate of perceived exertion and knee-joint-position sense assessed at rest, immediately after a standard warm-up (duration 25 min), and immediately after a competitive football match (90 minutes duration). Perceived exertion increased significantly from rest to the other assessments (rest: 8.6±2.0; after warm-up: 12.1±2.1; after football match: 18.5±1.3; p<0.001). Compared to rest, absolute angular error decreased significantly after the warm-up (4.1°±2.2° vs. 2.0°±1.0°; p=0.0045). After the match, absolute angular error (8.7°±3.8°) increased significantly comparatively to both rest (p=0.001) and the end of warm-up (p<0.001). Relative error showed directional bias with an underestimation of the target position, which was higher after the football match compared to both rest (p<0.001) and after warm-up (p<0.001). The results indicate that knee-joint-position sense acuity was increased by pre-participation warm-up exercise and was decreased by football match-induced fatigue. Warm-up exercises could contribute to knee injury prevention, whereas the deleterious effect of match-induced fatigue on the sensorimotor system could ultimately contribute to knee instability and injury.

HIV incidence is increasing among 13-24-year-old U.S. men who have sex with men, yet limited research is available to guide HIV prevention efforts for this population. National Survey of Family Growth data collected in 2002, in 2006-2010 and in 2011-2013 from 8,068 males aged 15-24 were analyzed to describe the population of U.S. young sexual minority males (i.e., males reporting same-sex attraction, identity or behavior). Correlates of sexual minority classification were assessed in logistic regression models. An estimated 10% of young males, representing a population of 2.1 million, were sexual minorities. Males had an elevated likelihood of being sexual minorities if they were aged 18-19 or 20-24, rather than 15-17 (prevalence ratio, 1.7 for each); belonged to nonblack, non-Hispanic racial or ethnic minority groups (1.6); had no religious affiliation, rather than considering religion very important (1.9); or lived below the federal poverty level (1.3). They had a reduced likelihood of being sexual minorities if they lived in metropolitan areas outside of central cities (0.7). Among young sexual minority males, 44% were 15-19 years old, 29% were poor and 59% resided outside central cities. Forty-seven percent had engaged in same-sex behavior. Of those with data on all measured dimensions of sexuality, 24% reported same-sex attraction, identity and behavior; 22% considered themselves heterosexual, yet had had a male sex partner. Future investigations can further explore subpopulations of young sexual minority males and assess sexual trajectories, resilience and HIV risk. Copyright © 2016 by the Guttmacher Institute.

RETURN TO DIVISION IA FOOTBALL FOLLOWING A 1ST METATARSOPHALANGEAL JOINT DORSAL DISLOCATION

Cook, Chad; Zarzour, Hap; Moorman, Claude T.

2010-01-01

Background. Although rare in occurrence, a dorsal dislocation of the 1st metatarsophalangeal (MTP) joint has been successfully treated using surgical and/or non-operative treatment. No descriptions of conservative intervention following a dorsal dislocation of the MTP joint in an athlete participating in a high contact sport are present in the literature. Objectives. The purpose of this case report is to describe the intervention and clinical reasoning during the rehabilitative process of a collegiate football player diagnosed with a 1st MTP joint dorsal dislocation. The plan of care and return to play criteria used for this athlete are presented. Case Description. The case involved a 19-year-old male Division IA football player, who suffered a traumatic dorsal dislocation of the 1st MTP joint during practice. The dislocation was initially treated on-site by closed reduction. Non-operative management included immobilization, therapeutic exercises, non-steroidal anti-inflammatories, manual treatment, modalities, prophylactic athletic taping, gait training, and a sport specific progression program for full return to Division IA football. Outcomes. Discharge from physical therapy occurred after six weeks of treatment. At discharge, no significant deviations existed during running, burst, and agility related drills. At a six-month follow-up, the patient reported full return to all football activities including contact drills without restrictions. Discussion. This case describes an effective six-week rehabilitation intervention for a collegiate football player who sustained a traumatic great toe dorsal dislocation. Further study is suggested to evaluate the intervention strategies and timeframe for return to contact sports. PMID:21589669

To examine the cardiovascular risk factors of professional football players of West-Asian and Black African descent competing in the 2010/11 Qatar Stars League. Ten out of twelve professional football clubs attended pre-participation screening. 100 West-Asian males from seven Gulf States and six Middle-Eastern countries and 90 Black males from seven African countries. All players were screened using the FIFA pre-competition medical assessment, incorporating a physical examination, resting 12-Lead ECG, echocardiogram, with determination of total cholesterol, high and low density lipoprotein (HDL/LDL) and triglycerides. West-Asian football players had a higher prevalence of a family history (FH) of coronary heart disease (CHD) (25% vs. 12%, p = 0.025) compared to Black African players predominantly due to CHD in their fathers (14% vs. 6%, p<0.05). West-Asian players had higher total cholesterol levels (4.4 vs. 4.2 mmol/L, p = 0.025) and lower HDL levels (1.3 vs. 1.4 mmol/L, p = 0.004) than Black African players; remaining significant after adjusting for a FH of CHD. Positively, all lipid levels were clinically acceptable for both ethnicities. Finally, one in eight West-Asian and one in eleven Black African football players were regular smokers. The prevalence of cardiovascular disease in West-Asia is increasing. This study observed clinically acceptable blood lipid profiles for both West-Asian and Black African football players. However, West-Asian players had a greater number of markers for CVD than their Black African counterparts despite being matched for physical activity levels. Targeted education with regards to diet, lifestyle and tobacco use is required for both ethnicities. Copyright © 2011 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

The present study aimed to evaluate the effect of footwear on standing balance in healthy young adult males. Thirty healthy male participants aged 20-30 years were tested for standing balance on the Balance Master on three occasions, including wearing a sandal, standard shoe, or no footwear (barefoot). The tests of postural stability include; "Modified Clinical Test of Sensory Interaction on Balance" (mCTSIB), "Unilateral Stance" (US), and the "Limits of Stability" (LOS). The balance scores (mCTSIB, US, and LOS) was analyzed. There was a significant effect between footwear conditions for mCTIB with eye closed on a firm surface (p=0.002). There was a significant effect between footwear conditions for the US with eye open and closed (p⟨0.05). There was a significant effect between footwear conditions for LOS reaction time during forward movement (p=0.02). Similarly, there was a significant effect between footwear conditions for LOS reaction time during left side movement (p=0.01). Wearing sandals compared to bare feet significantly increased postural sway and reduced stability in healthy young adult males. However, wearing a standard shoe compared to bare feet did not significantly affect balance scores in standing.

Effects of nine social life indicators on age-adjusted and age-specific annual suicide mortality of male and female Japanese population in the years 1953-96 were investigated by multiple regression analysis on time series data. Unemployment rate was significantly related to the age-adjusted mortality in both males and females. Also, female labour force participation was positively related to the male mortality; persons and 65 and above was inversely related to the male mortality. Results on the age-specific mortality indicated that: during the 44 yr, (1) unemployment significantly related with the mortality of young, middle-aged and elderly males and young females; (2) female labour force participation significantly related with the mortality of young and elderly males and young females; aged population significantly related with the mortality of middle-aged and elderly males; (4) young population significantly related with the mortality of young and middle-aged males and females; (5) divorce significantly related with the mortality of middle-aged and elderly males and young males and females; (6) persons employed in primary industries significantly related with the mortality in middle-aged males and young males and females; and (7) population density significantly related with the mortality of middle-aged males and young females.

Nutrition and hydration concerns of the female football player.

PubMed

Maughan, Ronald J; Shirreffs, Susan M

2007-08-01

There is little information on the nutritional habits of female football players at any level of the game. There is also a shortage of information on the nutrition and hydration strategies that players should adopt. In general, differences in nutritional needs between males and females are smaller than differences between individuals, so that principles developed for male players also apply to women. There is a need to address energy balance and body composition: prolonged energy deficits cannot be sustained without harm to health and performance. Published reports show mean carbohydrate intakes for female players of about 5 g/kg/day, and this seems to be too low to sustain consistent intensive training. The timing of protein intake may be as important as the amounts consumed, provided that the total intake is adequate. Dehydration adversely affects skill and stamina in women as it does in men, so an individualised hydration strategy should be developed. The prevalence of iron deficiency in women generally is high, but it seems to be alarmingly high in female players. All players should adopt dietary habits that ensure adequate iron intake. Football training seems to increase bone mass in the weight-bearing limbs, with positive implications for bone health in later life, but some players may be at risk from inadequate calcium dietary intake.

In Indiana, high school football coaches are required to complete a coaching education course with material related to concussion awareness, equipment fitting, heat emergency preparedness, and proper technique. Some high schools have also opted to implement a player safety coach (PSC). The PSC, an integral component of USA Football's Heads Up Football (HUF) program, is a coach whose primary responsibility is to ensure that other coaches are implementing proper tackling and blocking techniques alongside other components of the HUF program. To compare injury rates in Indiana high school football teams by their usage of a PSC or online coaching education only. Cohort study; Level of evidence, 2. Athletic trainers (ATs) evaluated and tracked injuries at each practice and game during the 2015 high school football season. Players were drawn from 6 teams in Indiana. The PSC group, which used the PSC component, was comprised of 204 players from 3 teams. The "education only" group (EDU), which utilized coaching education only, was composed of 186 players from 3 teams. Injury rates and injury rate ratios (IRRs) were reported with 95% confidence intervals (CIs). During 25,938 athlete-exposures (AEs), a total of 149 injuries were reported, of which 54 (36.2%) and 95 (63.8%) originated from the PSC and EDU groups, respectively. The practice injury rate was lower in the PSC group than the EDU group (2.99 vs 4.83/1000 AEs; IRR, 0.62; 95% CI, 0.40-0.95). The game injury rate was also lower in the PSC group than the EDU group (11.37 vs 26.37/1000 AEs; IRR, 0.43; 95% CI, 0.25-0.74). When restricted to concussions only, the rate was lower in the PSC group (0.09 vs 0.73/1000 AEs; IRR, 0.12; 95% CI, 0.01-0.94), although only 1 concussion was reported in the PSC group. No differences were found in game concussion rates (0.60 vs 4.39/1000 AEs; IRR, 0.14; 95% CI, 0.02-1.11). Findings support the PSC as an effective method of injury mitigation in high school football.

The Nordic hamstring (NH) exercise programme was introduced in 2001 and has been shown to reduce the risk of acute hamstring injuries in football by at least 50%. Despite this, the rate of hamstring injuries has not decreased over the past decade in male elite football. To examine the implementation of the NH exercise programme at the highest level of male football in Europe, the UEFA Champions League (UCL), and to compare this to the Norwegian Premier League, Tippeligaen, where the pioneer research on the NH programme was conducted. Retrospective survey. 50 professional football teams, 32 from the UCL and 18 from Tippeligaen. A questionnaire, based on the Reach, Efficacy, Adoption, Implementation and Maintenance framework, addressing key issues related to the implementation of the NH programme during three seasons from 2012 through 2014, was distributed to team medical staff using electronic survey software. The response rate was 100%. Of the 150 club-seasons covered by the study, the NH programme was completed in full in 16 (10.7%) and in part in an additional 9 (6%) seasons. Consequently, 125 (83.3%) club-seasons were classified as non-compliant. There was no difference in compliance between the UCL and Tippeligaen in any season (χ(2): 0.41 to 0.52). Adoption and implementation of the NH exercise programme at the highest levels of male football in Europe is low; too low to expect any overall effect on acute hamstring injury rates.

Young males' perspectives on pregnancy, fatherhood and condom use: Where does responsibility for birth control lie?

PubMed

Smith, Jennifer L; Fenwick, Jennifer; Skinner, Rachel; Merriman, Gareth; Hallett, Jonathan

2011-01-01

To improve our understanding of males' role in contraceptive practices, this paper explores the relationship between young males' perspectives on pregnancy and fatherhood and their attitudes, beliefs and practices in relation to condom use and birth control. Semi-structured interviews were conducted with a sample of 42 males aged 15-25 years. A systematic process of thematic analysis was used to reduce and organise the narrative data around the focus areas of relationships, sex, condom use, STIs and pregnancy/fatherhood. To facilitate the emergence of key patterns in the data, new data was constantly compared with existing ideas to formulate and refine codes and descriptive categories. The analysis revealed a clear discrepancy between young males' desire to prevent pregnancy and the level of control they assumed over this. Despite pregnancy emerging as the overriding concern for participants, this failed to motivate continued use of condoms when STI risk was perceived as low and a partner was using birth control. Reliance on a partner's use of hormonal contraceptives and in several cases, beliefs of low personal responsibility for pregnancy prevention reduced young males' participation in fertility control. Young males' unfavourable attitudes toward immediate pregnancy and fatherhood provide a unique opportunity for safe sex promotion by encouraging greater ownership over sexual and reproductive health outcomes. However, this requires a shift in the meanings associated with condoms, from a disease prevention only orientation to one that promotes condom use as a positive act for self and partner protection.

This study used oculomotor, cognitive, and multi-modal magnetic resonance imaging (MRI) measures to assess for neurological abnormalities in current asymptomatic amateur Australian rules footballers (i.e., Australia's most participated collision sport) with a history of sports-related concussion (SRC). Participants were 15 male amateur Australian rules football players with a history of SRC greater than 6 months previously, and 15 sex-, age-, and education-matched athlete control subjects that had no history of neurotrauma or participation in collision sports. Participants completed a clinical interview, neuropsychological measures, and oculomotor measures of cognitive control. MRI investigation involved structural imaging, as well as diffusion tensor imaging and resting-state functional MRI sequences. Despite no group differences on conventional neuropsychological tests and multi-modal MRI measures, Australian rules football players with a history of SRC performed significantly worse on an oculomotor switch task: a measure of cognitive control that interleaves the response of looking towards a target (i.e., a prosaccade) with the response of looking away from a target (i.e., an antisaccade). Specifically, Australian footballers performed significantly shorter latency prosaccades and found changing from an antisaccade trial to a prosaccade trial (switch cost) significantly more difficult than control subjects. Poorer switch cost was related to poorer performance on a number of neuropsychological measures of inhibitory control. Further, when comparing performance on the cognitively more demanding switch task with performance on simpler, antisaccade/prosaccades tasks which require a single response, Australian footballers demonstrated a susceptibility to increased cognitive load, compared to the control group who were unaffected. These initial results suggest that current asymptomatic amateur Australian rules football players with a history of SRC may have persisting

The purpose of this study was to identify differences in traits associated with muscle dysmorphia between collegiate football players (n=66), weight trainers for physique (n=115), competitive non-natural bodybuilders (n=47), and competitive natural bodybuilders (n=65). All participants completed demographic questionnaires in addition to the Muscle Dysmorphia Inventory (Rhea, Lantz, & Cornelius, 2004). Results revealed a significant main effect for group, and post hoc tests found that the non-natural bodybuilding group did not score significantly higher than the natural bodybuilding group on any subscale except for Pharmacological Use. Both the non-natural and natural bodybuilding groups scored significantly higher than those that weight trained for physique on the Dietary Behavior and Supplement Use subscales. The collegiate football players scored lowest on all subscales of the Muscle Dysmorphia Inventory except for Physique Protection where they scored highest. Findings are discussed with future research expounded.

Ergün, Metin; Denerel, H Nevzad; Binnet, Mehmet S; Ertat, K Ahmet

2013-01-01

The aim of this study was to investigate the incidence and nature of injuries and the influence of age on injury patterns in elite youth football. Fifty-two players of the Under-17 (U-17) male national youth football team were followed during their progression to U-18 and U-19. Individual player exposure and injuries were recorded during the three year study period. Injury incidence was five times higher during matches than training. When medical attention and time loss injuries were considered, injury incidence increased during matches and decreased during training with increasing age. Traumatic injuries were more frequent in matches and were linked with increased age. Overuse injuries were two times higher during training than matches in the U-17 team. The majority of traumatic match injuries (78.3%) led to time loss and the majority of time loss injuries occurred due to traumatic mechanism (62.1%). The majority of muscle and entire ligament injuries occurred during training and contusions during competition. Re-injury rate was 25% and were all overuse injuries. Injury incidences increased during matches and decreased during training. More match injuries were caused by traumatic mechanisms as players aged. Player age might contribute to injury incidence and characteristics in youth football.

To characterize the epidemiology of injuries in post-high school male and female athletes in the rapidly growing international sport of contact flag football. Prospective injury-observational study. Kraft Stadium, Jerusalem, Israel. A total of 1492 players, consisting of men (n = 1252, mean age, 20.49 ± 5.11) and women (n = 240, mean age, 21.32 ± 8.95 years), participated in 1028 games over a 2-season period (2007-2009). All time-loss injuries sustained in game sessions were recorded by the off-the-field medical personnel and followed up by a more detailed phone injury surveillance questionnaire. One hundred sixty-three injuries were reported, comprising 1 533 776 athletic exposures (AEs). The incidence rate was 0.11 [95% confidence interval (CI), 0.09-0.12] per 1000 AEs, and incidence proportion was 10.66% (95% CI, 9.10-12.22). Seventy-six percent of the injuries were extrinsic in nature. Thirty percent of the injuries were to the fingers, thumb, and wrist, 17% to the knee, 17% to the head/face, 13% to the ankle, and 11% to the shoulder. Contact flag football results in a significant amount of moderate to severe injuries. These data may be used in the development of a formal American flag football injury database and in the development and implementation of a high-quality, randomized, prospective injury prevention study. This study should include the enforcement of the no-pocket rule, appropriate headgear, self-fitting mouth guards, the use of ankle braces, and changing the blocking rules of the game.

Nutrition for the Australian Rules football player.

PubMed

Ebert, T R

2000-12-01

This review summarises past and present nutritional practices of Australian Rules Football players, noting changes that have occurred as the footballers have become more receptive to scientific input. Australian Rules Football is a unique sport, with matches involving intermittent high intensity sprints between periods of jogging and walking and repeated physical contact. Endurance, speed, strength, power and agility are essential physical characteristics. Australian Rules footballers exhibit a wide range of anthropometrical attributes due to the positional requirements of the game. Dietary surveys indicate that footballers of the 1980's consumed a diet similar to that of the general Australian population consisting of 44%, 37.5%, 15% and 3.5% of carbohydrate (CHO), fat, protein and alcohol, respectively. However, as dietitians are becoming an integral part of the support staff of teams there is evidence that nutritional practices conducive to optimal sporting performance are now being followed. Due to the prolonged duration and intermittent high intensity activity pattern of Australian Rules, nutritional supplementation such as fluid and CHO intake during training and competition and creatine intake may be beneficial; however, further research needs to be conducted in the field to determine its importance in Australian Rules Football.

American football is the largest participation sport in US high schools and is a leading cause of concussion among adolescents. Little is known about the long-term cognitive and mental health consequences of exposure to football-related head trauma at the high school level. To estimate the association of playing high school football with cognitive impairment and depression at 65 years of age. A representative sample of male high school students who graduated from high school in Wisconsin in 1957 was studied. In this cohort study using data from the Wisconsin Longitudinal Study, football players were matched between March 1 and July 1, 2017, with controls along several baseline covariates such as adolescent IQ, family background, and educational level. For robustness, 3 versions of the control condition were considered: all controls, those who played a noncollision sport, and those who did not play any sport. Athletic participation in high school football. A composite cognition measure of verbal fluency and memory and attention constructed from results of cognitive assessments administered at 65 years of age. A modified Center for Epidemiological Studies' Depression Scale score was used to measure depression. Secondary outcomes include results of individual cognitive tests, anger, anxiety, hostility, and heavy use of alcohol. Among the 3904 men (mean [SD] age, 64.4 [0.8] years at time of primary outcome measurement) in the study, after matching and model-based covariate adjustment, compared with each control condition, there was no statistically significant harmful association of playing football with a reduced composite cognition score (-0.04 reduction in cognition vs all controls; 97.5% CI, -0.14 to 0.05) or an increased modified Center for Epidemiological Studies' Depression Scale depression score (-1.75 reduction vs all controls; 97.5% CI, -3.24 to -0.26). After adjustment for multiple testing, playing football did not have a significant adverse association with

Fatal drink-driving accidents of young adult and middle-aged males--a risky driving style or risky lifestyle?

PubMed

2008-01-01

A range of situational and lifestyle-related factors in drink-driving fatal accidents were studied involving young adult and middle-aged male drivers in Finland. Fatal drink-driving accidents were compared to fatal accidents in which the driver had been sober. The study included all 18-to 59-year-old male drivers' fatal car and van accidents investigated by the Road Accident Investigation Teams in Finland between 2000 and 2002 (n = 366 accidents). The variables describing the situation included the time of the accident, the road condition, the speed, possession of a valid licence, seat-belt usage, and the presence of passengers. The study found that among young adult males most of the studied situational factors bore no relation to the state of the driver (sober or drink driver). Only the time of day, seat-belt, usage, and possession of a valid licence were related to the state of the driver. Among middle-aged male drivers, drink-driving and sober driving accidents differed more clearly. Further, when the social situation in the car was examined, it was found that accidents of sober and drink drivers differed from each other within the group of middle-aged drivers but not within the group of young adult drivers. Heavy alcohol usage was found to characterize the lifestyle of the studied middle-aged drink drivers. It was concluded that for young adult males drink-driving was a part of a more general risky driving style. Among middle-aged males drink-driving was more related to a risky lifestyle with drinking problems. Possible countermeasures are discussed with regard to drink-driving among young adult and middle-aged males.

Injuries in Rugby and Association Football

The number, site, severity and rate of accidents and the medical attention received has been measured for association and rugby football in the four northern counties of England during the 1970-1971 season. 696 out of 1601 (43%) association and 117 out of 232 (50%) rugby football clubs replied to the questionnaires. If all the clubs had replied an estimated 14078 injuries would have occurred in association and 3888 in rugby football. For soccer, the accident rate was 36.5 per 10,000 man-hours of play and for rugger 30.5. In soccer 65% of all injuries were to the lower limbs, but only 36% in rugger, which had a higher proportion of injuries to other sites compared with soccer. Fractures and dislocations were twice as common in rugger as in soccer. Concussion was also more common. In rugby football, the players are injured less often than in association football, but more seriously, as is shown by the fact that hospital treatment was needed by 29.8% of the soccer injuries, but 52.8% of those in rugby football. Similarly, a rugger injury needed on average 12 days off play, whereas one in soccer needed only 6 days off play. A bigger proportion of soccer injuries (73.8%) received rapid first aid than did rugger injuries (45.8%). Better first aid cover at matches and simple protective clothing for the legs of soccer players and shoulders of rugby players are suggested.

Alghadir, Ahmad H.; Zafar, Hamayun; Anwer, Shahnawaz

2018-01-01

Objective: The present study aimed to evaluate the effect of footwear on standing balance in healthy young adult males. Methods: Thirty healthy male participants aged 20-30 years were tested for standing balance on the Balance Master on three occasions, including wearing a sandal, standard shoe, or no footwear (barefoot). The tests of postural stability include; “Modified Clinical Test of Sensory Interaction on Balance” (mCTSIB), “Unilateral Stance” (US), and the “Limits of Stability” (LOS). The balance scores (mCTSIB, US, and LOS) was analyzed. Results: There was a significant effect between footwear conditions for mCTIB with eye closed on a firm surface (p=0.002). There was a significant effect between footwear conditions for the US with eye open and closed (p<0.05). There was a significant effect between footwear conditions for LOS reaction time during forward movement (p=0.02). Similarly, there was a significant effect between footwear conditions for LOS reaction time during left side movement (p=0.01). Conclusions: Wearing sandals compared to bare feet significantly increased postural sway and reduced stability in healthy young adult males. However, wearing a standard shoe compared to bare feet did not significantly affect balance scores in standing. PMID:29504581

The aim of the present study was to describe the lifetime occurrence and associated factors of anabolic-androgenic steroids (AAS) among young Finnish males. Of the 10 829 male conscripts (median age 19), 10 396 (96%) answered a questionnaire during the first days of their conscription in the years 2001-2007. The main outcome was lifetime AAS use. We also studied associations between 13 socioeconomic, health, and health behavioral background variables and AAS use by logistic regression. Eighty-nine (0.9%) respondents reported having used AAS. In addition, 26 (0.3%) respondents reported that they would use AAS if they could obtain them. In multivariate analysis, which included all significant variables and age, the strongest associated factors were weight training at fitness centers more than three times a week [odds ratio (OR) 11.8; 95% confidence interval (CI): 7.1-19.6], low educational status (OR 3.7; 95% CI: 2.0-7.0), and weekly drunkenness as drinking style (OR 2.4; 95% CI: 1.4-4.5). Sports other than weight training were not associated with AAS in our sample. The use of AAS is relatively uncommon among Finnish males. It is strongly associated with weight training at fitness centers but also with lower educational status and a drunkenness-oriented lifestyle. Prevention should be targeted at those males participating in weight training.

The influence of injuries on team performance in football has only been scarcely investigated. To study the association between injury rates and team performance in the domestic league play, and in European cups, in male professional football. 24 football teams from nine European countries were followed prospectively for 11 seasons (2001-2012), including 155 team-seasons. Individual training and match exposure and time-loss injuries were registered. To analyse the effect of injury rates on performance, a Generalised Estimating Equation was used to fit a linear regression on team-level data. Each team's season injury rate and performance were evaluated using its own preceding season data for comparison in the analyses. 7792 injuries were reported during 1 026 104 exposure hours. The total injury incidence was 7.7 injuries/1000 h, injury burden 130 injury days lost/1000 h and player match availability 86%. Lower injury burden (p=0.011) and higher match availability (p=0.031) were associated with higher final league ranking. Similarly, lower injury incidence (p=0.035), lower injury burden (p<0.001) and higher match availability (p<0.001) were associated with increased points per league match. Finally, lower injury burden (p=0.043) and higher match availability (p=0.048) were associated with an increase in the Union of European Football Association (UEFA) Season Club Coefficient, reflecting success in the UEFA Champions League or Europa League. Injuries had a significant influence on performance in the league play and in European cups in male professional football. The findings stress the importance of injury prevention to increase a team's chances of success.

Male adolescents and young men benefit when their mental health care is specialized to match their unique gendered and developmental needs. Sensitivity to the social circumstances of this population is important; additionally, the emerging ability to tailor care through knowledge gleaned from the intersection of psychiatry, neurology, and endocrinology informs care. This article summarized the views of six experts in the area of the adolescent and young adult male mental health. These experts were select members of the World Federation of Societies of Biological Psychiatry's Task Force on Men's Mental Health. They convened to present two symposia on the topic of men's mental health at the 13th World Congress of Biological Psychiatry (WCBP) in Copenhagen, Denmark in 2017. In these works, a special focus is paid to addictive disorders, disruptive behavior disorders, aggression, and brain development. Collectively, the authors present an argument for the merits of a male-specific model of mental health care to advance the overall well-being of this population. Men's mental health should be recognized as a social issue as much as a medical issue, with special attention paid to problems such as unemployment, familial disruption, and substance abuse. These problems, and especially those of major societal impact including violence and suicide which are much more frequently the product of male youth and men, should have more male-tailored options for service provision that respond to men's mental health needs.

Mental toughness profiles and their relations with achievement goals and sport motivation in adolescent Australian footballers.

PubMed

Gucciardi, Daniel F

2010-04-01

The aims of this study were to identify the mental toughness profiles of adolescent Australian footballers and to explore the relations between the mental toughness clusters and achievement goals and sport motivation. A total of 214 non-elite, male Australian footballers aged 16-18 years (mean = 16.8, s = 0.7) provided self-reports of mental toughness, achievement goals, and sport motivation. Cluster analysis supported the presence of two-groups in which players evidenced moderate and high levels of all four mental toughness subscales. Significant multivariate effects were observed for achievement goals and sport motivation with the high mental toughness group favouring both mastery- and performance-approach goals and self-determined as well as extrinsic motivational tendencies. The results suggest that adolescent Australian footballers' self-perceptions of mental toughness fall within two clusters involving high and moderate forms of all four components, and that these profiles show varying relations with achievement goals (particularly mastery-approach) and sport motivation.

Our understanding of the effects of football code participation on low back pain (LBP) is limited. It is unclear whether LBP is more prevalent in athletic populations or differs between levels of competition. Thus it was the aim of this study to document and compare the prevalence, intensity, quality and frequency of LBP between elite and semi-elite male Australian football code participants and a non-athletic group. A cross-sectional survey of elite and semi-elite male Australian football code participants and a non-athletic group was performed. Participants completed a self-reported questionnaire incorporating the Quadruple Visual Analogue Scale (QVAS) and McGill Pain Questionnaire (short form) (MPQ-SF), along with additional questions adapted from an Australian epidemiological study. Respondents were 271 elite players (mean age 23.3, range 17-39), 360 semi-elite players (mean age 23.8, range 16-46) and 148 non-athletic controls (mean age 23.9, range 18-39). Groups were matched for age (p = 0.42) and experienced the same age of first onset LBP (p = 0.40). A significant linear increase in LBP from the non-athletic group, to the semi-elite and elite groups for the QVAS and the MPQ-SF was evident (p < 0.001). Elite subjects were more likely to experience more frequent (daily or weekly OR 1.77, 95% CI 1.29-2.42) and severe LBP (discomforting and greater OR 1.75, 95% CI 1.29-2.38). Foolers in Australia have significantly more severe and frequent LBP than a non-athletic group and this escalates with level of competition.

Introduction: In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP) among young adult male smokers. Methods: A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18–45 years old. Results: The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811), and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364)  in the sample of higher education young adult males Conclusions: Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers. PMID:25689992

The majority of football injuries are caused by trauma to the lower extremities. Shinguards are considered an important measure in preventing lower leg impact abrasions, contusions and fractures. Given these benefits, Fédération Internationale de Football Association introduced the shinguard law in 1990, which made wearing shinguards during matches mandatory. This study evaluated the effect of the introduction of the shinguard law for amateur players in the Netherlands in the 1999/2000-football season on the incidence of lower leg injuries. Time trend analyses on injury data covering 25 years of continuous registration (1986-2010). Data were retrieved from a system that records all emergency department treatments in a random, representative sample of Dutch hospitals. All injuries sustained in football by patients aged 6-65 years were included, except for injuries of the Achilles tendon and Weber fractures. Time trends were analysed with multiple regression analyses; a model was fitted consisting of multiple straight lines, each representing a 5-year period. Patients were predominantly males (92%) and treated for fractures (48%) or abrasions/contusions (52%) to the lower leg. The incidence of lower leg football injuries decreased significantly following the introduction of the shinguard law (1996-2000: -20%; 2001-2005: -25%), whereas the incidence of all other football injuries did not. This effect was more prominent at weekends/match days. No gender differences were found. The results significantly show a preventive effect of the shinguard law underlining the relevance of rule changes as a preventive measure and wearing shinguards during both matches and training sessions.

1993-12-01

Computerised data of 110,236 Singaporean males aged 15 to 25 (mean 17.75) years who underwent compulsory medical examination from April 1987 to January 1992 were used to estimate the prevalence and severity of myopia among young Chinese, Malay, Indian and Eurasian Singaporean males with different educational levels. The prevalence and severity of myopia amongst the groups with different educational levels were compared. These groups were fairly well-matched for important known confounding factors such as age, sex, race and degree of urbanisation of place of residence. Our data showed a positive association between educational attainment and both the prevalence and severity of myopia. Both the prevalence of myopia and the proportion of myopes with severe myopia were in general higher among those with more years of formal education.

The health benefits of playing football and the importance of exercise and social contact for healthy ageing are well established, but few older adults in the UK take enough exercise. Football is popular, flexible in format and draws players into engrossing, effortful and social exercise, but the physical demands of play at full speed may make it unsustainable for some older adults. Restricted to walking pace, will play still be engaging? Will health benefits be retained? Will physical demands remain manageable? This pilot study aims to investigate: (1) the experience of older adults playing walking football every week, is it sustainable and rewarding, (2) the intensity and locomotor pattern of walking football, (3) the scale and nature of walking football health benefits and (4) possible cognitive benefits of playing walking football through measures of processing speed, selective and divided attention and updating and inhibition components of executive function.
 'Walking football' and 'waiting list' groups were compared before and after 12 weeks of one-hour per week football. Walking football was found to be engaging, sustainable for older adults and moderately intensive; however, selective health and cognitive benefits were not found from this brief intervention. Highlights Walking football is a lower impact but authentic form of football that enables older players to extend their active participation. Walking football is enjoyable and moderately demanding and may be a sustainable form of exercise for older adults. Health and cognitive benefits to playing walking football were not found.

Why Professional Football Players Chose Not to Reveal Their Concussion Symptoms During a Practice or Game.

To determine why professional football players in Canada decided not to seek medical attention during a game or practice when they believed they had suffered a concussion. Retrospective survey. Preseason Canadian Football League training camps. Four hundred fifty-four male professional football players. Reasons athletes did not seek medical attention for a presumed concussion during the previous season, how often this occurred and how important these reasons were in the decision process. One hundred six of the 454 respondents (23.4%) believed they had suffered a concussion during their previous football season and 87 of the 106 (82.1%) did not seek medical attention for a concussion at least once during that season. The response "Did not feel the concussion was serious/severe and felt you could still continue to play with little danger to yourself" was the most commonly listed reason (49/106) for not seeking medical attention for a presumed concussion. Many players answered that they did not seek medical attention because they did not want to be removed from a game (42/106) and/or they did not want to risk missing future games (41/106) by being diagnosed with a concussion. Some professional football players who believed they had suffered a concussion chose not to seek medical attention at the time of injury. Players seemed educated about the concussion evaluation process and possible treatment guidelines, but this knowledge did not necessarily translate into safe and appropriate behavior at the time of injury.

University Football Players, Postural Stability, and Concussions.

Concussion in football athletes is certainly more prevalent and has potentially serious outcomes. With current concerns and increasing return-to-play issues, additional assessment focus is needed. Division 1 college football athletes, from 18 to 20.9 years (n = 177; age, 19.7 ± 1.2 years; height, 182.3 ± 4.5 cm; weight, 97.3 ± 10.6 kg), before fall practice, over a period of 3 years, underwent baseline postural stability testing (sensory organization test [SOT], NeuroCom). Individuals, who were diagnosed with a concussion (headache, dizziness, fatigue, confusion, or loss of consciousness) during practice or actual competition (n = 15; age, 18.9 ± 0.9 years; height, 181.8 ± 2.5 cm; weight, 86.6 ± 3.6 kg), underwent serial evaluation after injury and 24 hours after concussion. As soon as the player was considered asymptomatic, the test was completed on the first and 14th day. A control group of noninjured male athletes (n = 15; age, 19.1 ± 0.4 years; height, 178.2 ± 3.2 cm; weight, 78.6 ± 2.1 kg) were tested for the same time frame. This particular study was only one part of the total evaluation conducted for the concussed athlete's return to play. Results indicated that the concussion group had a statistically significant (p = 0.037) change from their baseline SOT score and the control group (p = 0.025). This change remained significant until day 14 of posttesting. These data indicate that the SOT, when available, may be a positive additional assessment of concussed college-aged football players. Professionals, when dealing with concussion in competitive sports, do need to continue to work together, but awareness of SOT assessments may also contribute to the return-to-play decisions.

Training in élite young athletes (the Training of Young Athletes (TOYA) Study): injuries, flexibility and isometric strength.

Using a mixed longitudinal design, the incidence of injuries, and the development of flexibility and isometric strength of the upper and lower limbs were studied for 2 years in 453 élite young athletes (aged between 9 and 18 years) practising football, gymnastics, swimming or tennis. The children suffered from a low incidence of injuries. Strength and flexibility did not exert a significant role in determining injuries. The rate of injury was not significantly different between the 2 years of the study. Young swimmers showed a greater generalized flexibility. Girls were more flexible than boys between the ages of 13 to 16 years. Athletic children are able to exert greater isometric strength than normal schoolchildren. Boys diverged from the normal population at 14 years, while athletic girls were stronger at all ages. Girls were stronger than boys up to age 12, who were still increasing their muscle strength at 19 years. The average maximal isometric strength exerted in both upper and lower limbs in the four sports was not significantly different. Male gymnasts over 11 years old were significantly stronger than all other athletes. PMID:7921912

Head impact exposure in youth football.

2012-04-01

The head impact exposure for athletes involved in football at the college and high school levels has been well documented; however, the head impact exposure of the youth population involved with football has yet to be investigated, despite its dramatically larger population. The objective of this study was to investigate the head impact exposure in youth football. Impacts were monitored using a custom 12 accelerometer array equipped inside the helmets of seven players aged 7-8 years old during each game and practice for an entire season. A total of 748 impacts were collected from the 7 participating players during the season, with an average of 107 impacts per player. Linear accelerations ranged from 10 to 100 g, and the rotational accelerations ranged from 52 to 7694 rad/s(2). The majority of the high level impacts occurred during practices, with 29 of the 38 impacts above 40 g occurring in practices. Although less frequent, youth football can produce high head accelerations in the range of concussion causing impacts measured in adults. In order to minimize these most severe head impacts, youth football practices should be modified to eliminate high impact drills that do not replicate the game situations.

High School Football Players Use Their Helmets to Tackle Other Players Despite Knowing the Risks

There is greater attention to head-related injuries and concussions in American football. The helmet's structural safety and the way that football players use their helmets are important in preventing head injuries. Current strategies include penalizing players for high-risk behavior such as leading with their helmet or hitting an opposing player above the shoulder. Passive strategies include helmet modification to better protect the head of the players or to change the playing style of the players. Hawai‘i high school varsity football players were surveyed to determine how they use their helmets and how a new helmet design would affect their style of play. One hundred seventy-seven surveys were completed; 79% said that they used their helmet to hit an opposing player during a tackle and 46% said they made this contact intentionally. When asked about modifying helmets with a soft material on the outside, 48% said they thought putting a soft cover over a regular helmet would protect their head better. However, many participants said that putting a soft cover over their regular helmet was a bad idea for various reasons. Most young football players use their helmets to block or tackle despite being taught they would be penalized or potentially injured if they did so. By gaining a better understanding of why and how players use their helmets and how they would respond to new helmet designs, steps can be taken to reduce head injuries for all levels of play.

To investigate changes from baseline on SCAT3 as a result of football game exposure, and association with X2 Patch measured head acceleration events in amateur Australian footballers. Prospective cohort. Peak linear acceleration (PLA) of the head (>10 g) was measured by wearable head acceleration sensor X2 Biosystems X-Patch in male (n=34) and female (n=19) Australian footballers. SCAT3 was administered at baseline (B) and post-game (PG). 1394 head acceleration events (HEA) >10 g were measured. Mean and median HEA PLA were recorded as 15.2 g (SD=9.2, range=10.0-115.8) and 12.4 g (IQR=11.0-15.6) respectively. No significant difference in median HEA PLA (g) was detected across gender (p=0.55), however, more HEAs were recorded in males (p=0.03). A greater number (p=0.004) and severity (p<0.001) of symptoms were reported PG than at B. No significant association between number of HEA or median PLA, and SCAT3 change scores (p>0.05 for all), was identified for either gender. Increase in symptom severity post game was not associated with X2 measured HEA. Males sustained more HEA, however HEA PLA magnitude did not differ across gender. Further work on the validation of head acceleration sensors is required and their role in sports concussion research and medical management. Copyright © 2017 Sports Medicine Australia.

Epidemiology of neurodegeneration in American-style professional football players

2013-01-01

The purpose of this article is to review the history of head injuries in relation to American-style football play, summarize recent research that has linked football head injuries to neurodegeneration, and provide a discussion of the next steps for refining the examination of neurodegeneration in football players. For most of the history of football, the focus of media reports and scientific studies on football-related head injuries was on the acute or short-term effects of serious, traumatic head injuries. Beginning about 10 years ago, a growing concern developed among neurologists and researchers about the long-term effects that playing professional football has on the neurologic health of the players. Autopsy-based studies identified a pathologically distinct neurodegenerative disorder, chronic traumatic encephalopathy, among athletes who were known to have experienced concussive and subconcussive blows to the head during their playing careers. Football players have been well represented in these autopsy findings. A mortality study of a large cohort of retired professional football players found a significantly increased risk of death from neurodegeneration. Further analysis found that non-line players were at higher risk than line players, possibly because of an increased risk of concussion. Although the results of the studies reviewed do not establish a cause effect relationship between football-related head injury and neurodegenerative disorders, a growing body of research supports the hypothesis that professional football players are at an increased risk of neurodegeneration. Significant progress has been made in the last few years on detecting and defining the pathology of neurodegenerative diseases. However, less progress has been made on other factors related to the progression of those diseases in football players. This review identifies three areas for further research: (a) quantification of exposure - a consensus is needed on the use of clinically

Steinach and Young, Discoverers of the Effects of Estrogen on Male Sexual Behavior and the "Male Brain".

PubMed

Södersten, Per

2015-01-01

In the 1930s, Eugen Steinach's group found that estradiol induces lordosis in castrated rats and reduces the threshold dose of testosterone that is necessary for the induction of ejaculation, and that estradiol-treated intact rats display lordosis as well as mounting and ejaculation. The bisexual, estrogen-sensitive male had been demonstrated. Another major, albeit contrasting, discovery was made in the 1950s, when William Young's group reported that male guinea pigs and prenatally testosterone-treated female guinea pigs are relatively insensitive to estrogen when tested for lordosis as adults. Reduced estrogen sensitivity was part of the new concept of organization of the neural tissues mediating the sexual behavior of females into tissues similar to those of males. The importance of neural organization by early androgen stimulation was realized immediately and led to the discovery of a variety of sex differences in the brains of adult animals. By contrast, the importance of the metabolism of testosterone into estrogen in the male was recognized only after a delay. While the finding that males are sensitive to estrogen was based on Bernhard Zondek's discovery in 1934 that testosterone is metabolized into estrogen in males, the finding that males are insensitive to estrogen was based on the hypothesis that testosterone-male sexual behavior is the typical relationship in the male. It is suggested that this difference in theoretical framework explains the discrepancies in some of the reported results.

Although hypertension is common among American-style football players, the presence of concomitant vascular dysfunction has not previously been characterized. We sought to examine the impact of American-style football participation on arterial stiffness and to compare metrics of arterial function between collegiate American-style football participants and non-athletic collegiate controls. Newly matriculated collegiate athletes were studied longitudinally during a single season of American-style football participation and were then compared to healthy undergraduate controls. Arterial stiffness was characterized by use of applanation tonometry (SphygmoCor®). American-style football participants (N = 32, 18.4 ± 0.5 years old) were evenly comprised of Caucasians (N = 14, 44%) and African-Americans (N = 18, 56%). A single season of American-style football participation led to an increase in central aortic pulse pressure (27 ± 4 vs. 34 ± 8 mm Hg, P <0.001). Relative to controls (N = 47), pulse wave velocity was increased among ASF participants (5.6 ± 0.7 vs. 6.2 ± 0.9 m/s, P = 0.002). After adjusting for height, weight, body-mass index, systolic blood pressure, and diastolic blood pressure, American-style football participation was independently predictive of increased pulse wave velocity (β = 0.33, P = 0.04). In conclusion, American-style football participation leads to changes in central hemodynamics and increased arterial stiffness. PMID:25465938

A 33-year-old male professional football player suffered from acute-onset dizziness following a lower limb soft tissue treatment in prone lying. Symptoms included spinning vertigo lasting for 30's, headache, visual vertigo and disorientation. Clinical examination of balance and vestibular systems confirmed a left posterior canalithiasis benign paroxysmal positional vertigo (BPPV) and excluded other central and peripheral causes of dizziness. Two cycles of a left Epley manoeuvre were performed. An Epley manoeuvre abolished the BPPV and negated the need for medication. The player was able to return to play without dizziness within 24 hours completely symptom free. BPPV can be successfully identified and treated in elite football players and they can see a return to training and games within 24 hours. There are no epidemiology studies for this group of elite athletes either male or female despite increased occupational risk factors. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Descriptive epidemiology study. United States, 2003-2007. People ages 15 years and older who experienced an emergency department-treated injury while playing basketball, football, or soccer. Rates of emergency department-treated injuries resulting from participation in basketball, football, or soccer. Injury rates were calculated for people ages 15 and older for the years 2003-2007 using the U.S. population and hours of participation as the denominators. The risk of injury associated with each of these sports was compared for all participants and by sex. From 2003 through 2007, annual injury rates per 1000 U.S. population were as follows: 1.49 (95% confidence interval [CI] = 1.30, 1.67) in basketball, 0.93 (95% CI = 0.82, 1.04) in football, and 0.43 (95% CI = 0.33, 0.53) in soccer. When the denominator was hours of participation, the injury rate in football (5.08 [95% CI = 4.46, 5.69]/10 000 hours) was almost twice as high as that for basketball (2.69 [95% CI = 2.35, 3.02]/10 000 hours) and soccer (2.69 [95% CI = 2.07, 3.30]/10 000 hours). Depending on the choice of denominator, interpretation of the risk of an emergency department-treated injury in basketball, football, or soccer varies greatly. Using the U.S. population as the denominator produced rates that were highest in basketball and lowest in soccer. However, using hours of participation as a more accurate measure of exposure demonstrated that football had a higher rate of injury than basketball or soccer for both males and females.

The need for simple, valid techniques of body composition assessment among athletes is a growing concern of the physical therapist. This paper reports on several common methods applied to university football players. Body composition analysis was conducted on 28 Division IA football players using three different bioelectrical impedance analysis (BIA) systems, skinfolds (SF), and hydrostatic weighing (HYDRO). Correlations for all methods with HYDRO were high (>.88), but BIA significantly overpredicted body fatness. In contrast, three SF equations showed small differences with HYDRO and reasonable measurement error. Clinicians should exercise caution when using BIA based on the existing manufacturers' equations with athletic populations. Adjustments to BIA regression equations by including modifying or anthropometric variables could enhance the predictive accuracy of these methods with lean, athletic males.

Studying the neural correlates of smoking behaviors in young adulthood is of great importance to improve treatment outcomes. In previous addiction studies, the important roles of the salience network (SN) in drug cue processing and cognitive control have been revealed. Unfortunately, few studies focused on the resting-state functional connectivity and structural integrity abnormalities of SN in young adult smokers, and less is known about its association with smoking behaviors and cognitive control deficits. Thirty-one young male adult smokers and 30 age-, education- and gender-matched nonsmokers participated in this study. The structural and functional connectivity differences of SN were investigated between young adult smokers and nonsmokers by using diffusion tensor imaging (DTI) and resting-state functional connectivity (RSFC), which were then correlated with the smoking behavioral assessments (pack-years and Fagerström Test for Nicotine Dependence (FTND)) as well as impaired cognitive control measured by the Stroop task. Within SN, reduced RSFC and increased fractional anisotropy (FA) were found between the anterior cingulate cortex (ACC) and the right insula in young adult smokers relative to nonsmokers. The RSFC between the ACC and right insula was negatively correlated with the number of errors during the incongruent condition of the Stroop task in young adult smokers. Additionally, the right insula-ACC RSFC was negatively correlated with pack-years in young adult smokers. Our results revealed abnormal RSFC and structural integrity within the SN in young adult smokers, which shed new insights into the neural mechanism of nicotine dependence.

Identifying and understanding injury risk factors are necessary to target the injury-prone athlete and develop injury prevention measurements. The influence of psychological factors on injuries in football is poorly documented. The purpose of this 8-month prospective cohort study therefore was to examine whether psychological player characteristics assessed by a self-administered questionnaire represent risk factors for injury. At baseline, female football players (14-16 years) were asked to complete a detailed questionnaire covering player history, previous injuries, perception of success and motivational climate, life stress, anxiety and coping strategies. During the 2005 season, a total of 1430 players were followed up to record injuries. A history of a previous injury [odds ratio (OR)=1.9 (1.4; 2.5), P<0.001] increased the risk of a new injury to the same region. There were significant differences in disfavor for previously injured compared with non-injured players for ego orientation (P=0.007), perception of a performance climate (P=0.003) and experienced stressful life events (P<0.001). However, only high life stress (P=0.001) and perception of a mastery climate (P=0.03) were significant risk factors for new injuries. In conclusion, a perceived mastery climate and a high level of life stress were significant predictors for new injuries in a cohort of young female football players.

To characterize interhemispheric functional and anatomical connectivity and their relationships with impulsive behaviour in codeine-containing cough syrup (CCS)-dependent male adolescents and young adults. We compared volumes of corpus callosum (CC) and its five subregion and voxel-mirrored homotopic functional connectivity (VMHC) in 33 CCS-dependent male adolescents and young adults and 38 healthy controls, group-matched for age, education and smoking status. Barratt impulsiveness scale (BIS.11) was used to assess participant impulsive behaviour. Abnormal CC subregions and VMHC revealed by group comparison were extracted and correlated with impulsive behaviour and duration of CCS use. We found selective increased mid-posterior CC volume in CCS-dependent male adolescents and young adults and detected decreased homotopic interhemispheric functional connectivity of medial orbitofrontal cortex (OFC). Moreover, impairment of VMHC was associated with the impulsive behaviour and correlated with the duration of CCS abuse in CCS-dependent male adolescents and young adults. These findings reveal CC abnormalities and disruption of interhemispheric homotopic connectivity in CCS-dependent male adolescents and young adults, which provide a novel insight into the impact of interhemispheric disconnectivity on impulsive behaviour in substance addiction pathophysiology. • CCS-dependent individuals (patients) had selective increased volumes of mid-posterior corpus callosum • Patients had attenuated interhemispheric homotopic FC (VMHC) of bilateral orbitofrontal cortex • Impairment of VMHC correlated with impulsive behaviour in patients • Impairment of VMHC correlated with the CCS duration in patients.

To assess the seroprevalence and seroconversion of Epstein-Barr virus (EBV) and cytomegalovirus (CMV) Immunoglobulin G (IgG) antibodies and identify associated socioeconomic and smoking variables among male young adults in Israel, to explore health disparities and aid prevention efforts. A population-based seroprevalence study of EBV and CMV IgG antibodies in a systematic sample of Israeli males upon recruitment to mandatory military service during 1994-2004. Associations between socioeconomic and smoking variables and the seroprevalence of EBV/CMV were evaluated, controlling for possible confounders. A subset of seronegative subjects was assessed for seroconversion upon discharge from military service. Overall seroprevalence rates were 87% for EBV and 59% for CMV. An association between the seroprevalence of EBV and CMV was observed. Seroconversion was 56% for EBV as compared with 31% for CMV. Lower paternal education was found to be associated with both EBV and CMV seroprevalence. Lower socioeconomic status, North African origin, and urban residence were found to be associated with CMV seropositivity, as was smoking for EBV seropositivity. Socioeconomic disparities exist in the seroprevalence rates of CMV and EBV among Israeli male young adults. The results of the study could aid public health efforts and determine target populations when a vaccine becomes available. Copyright © 2012 Elsevier Inc. All rights reserved.

The purpose of this study is to describe an association of unilateral multifocal choroiditis (MFC), retinal vasculitis, optic neuropathy, and bilateral keratoconus in a young Saudi male. A 27-year-old male patient with stable bilateral keratoconus presented with a painless vision loss in his left eye. Ophthalmic examinations revealed multiple foci of idiopathic chorioretinitis, retinal vasculitis, and mild optic disc leakage on fluorescein angiography, all of which resolved on systemic therapy with mycophenolate mofetil and prednisone after 3 months. Systemic medication was stopped after 8 months. One year after presentation, patient's visual acuity has improved and remained stable. Systemic immunomodulatory therapy can be effective in managing and leading to resolution of MFC, retinal vasculitis, and optic disc leak in young patients.

To determine the risk of concussion among youth football players (ages 8-12 years). Participants included 468 male youth football players in western Pennsylvania during the 2011 youth football season. Incidence rates (IRs) and incidence density ratios (IDRs) of concussion were calculated for games and practices and for age groups. There was a total of 11,338 (8415 practice and 2923 game) athletic exposures (AEs) in the study period, during which 20 medically diagnosed concussions occurred. A majority of concussions were the result of head-to-head (45%) contact. The combined concussion IR for practices and games was 1.76 per 1000 AEs (95% CI 0.99-2.54). The concussion IR was 0.24 per 1000 AEs (95% CI 0.04-0.79) in practices and 6.16 per 1000 AEs (95% CI 3.76-9.54) in games. The IDR for concussions in games to practices was 25.91 (95% CI 6.01-111.70). The IDR of concussions for youth aged 11-12 years compared with youth aged 8-10 years was 2.72 (95% CI 0.66-4.78). The overall IR for concussion in youth football players aged 8-12 years was comparable with that reported previously for high school and collegiate samples. However, participation in games was associated with an increase in risk of concussion compared with practices, which was higher than rates previously reported for high school and collegiate athletes. Younger players were slightly less likely to incur a concussion than were older players. Copyright © 2013 Mosby, Inc. All rights reserved.

To evaluate the test-retest reliability, sensitivity, and concurrent validity of a smartphone-based method for assessing eccentric hamstring strength among male professional football players. A total of 25 healthy male professional football players performed the Chinese University of Hong Kong (CUHK) Nordic break-point test, hamstring fatigue protocol, and isokinetic hamstring strength test. The CUHK Nordic break-point test is based on a Nordic hamstring exercise. The Nordic break-point angle was defined as the maximum point where the participant could no longer support the weight of his body against gravity. The criterion for the sensitivity test was the presprinting and postsprinting difference of the Nordic break-point angle with a hamstring fatigue protocol. The hamstring fatigue protocol consists of 12 repetitions of the 30-m sprint with 30-s recoveries between sprints. Hamstring peak torque of the isokinetic hamstring strength test was used as the criterion for validity. A high test-retest reliability (intraclass correlation coefficient = .94; 95% confidence interval, .82-.98) was found in the Nordic break-point angle measurements. The Nordic break-point angle significantly correlated with isokinetic hamstring peak torques at eccentric action of 30°/s (r = .88, r 2  = .77, P < .001). The minimal detectable difference was 8.03°. The sensitivity of the measure was good enough that a significance difference (effect size = 0.70, P < .001) was found between presprinting and postsprinting values. The CUHK Nordic break-point test is a simple, portable, quick smartphone-based method to provide reliable and accurate eccentric hamstring strength measures among male professional football players.

Little is known about the prevalence and associated of morbidity of tendon problems. With only severe cases of tendon problems missing games, players that have their training and performance impacted are not captured by traditional injury surveillance. The aim of this study was to report the prevalence of Achilles and patellar tendon problems in elite male Australian football players using the Oslo Sports Trauma Research Centre (OSTRC) overuse questionnaire, compared to a time-loss definition. Male athletes from 12 professional Australian football teams were invited to complete a monthly questionnaire over a 9-month period in the 2016 pre- and competitive season. The OSTRC overuse injury questionnaire was used to measure the prevalence and severity of Achilles and patellar tendon symptoms and was compared to traditional match-loss statistics. A total of 441 participants were included. Of all participants, 21.5% (95% CI: 17.9-25.6) and 25.2% (95% CI 21.3-29.4) reported Achilles or patellar tendon problems during the season, respectively. Based on the traditional match-loss definition, a combined 4.1% of participants missed games due to either Achilles or patellar tendon injury. A greater average monthly prevalence was observed during the pre-season compared to the competitive season. Achilles and patellar tendon problems are prevalent in elite male Australian football players. These injuries are not adequately captured using a traditional match-loss definition. Prevention of these injuries may be best targeted during the off- and pre-season due to higher prevalence of symptoms during the pre-season compared to during the competitive season. © 2018 John Wiley & Sons A/S.

Over the period 1980-2009, there were 58 documented hyperthermia deaths of American-style football players in the United States. This study examines the geography, timing, and meteorological conditions present during the onset of hyperthermia, using the most complete dataset available. Deaths are concentrated in the eastern quadrant of the United States and are most common during August. Over half the deaths occurred during morning practices when high humidity levels were common. The athletes were typically large (79% with a body mass index >30) and mostly (86%) played linemen positions. Meteorological conditions were atypically hot and humid by local standards on most days with fatalities. Further, all deaths occurred under conditions defined as high or extreme by the American College of Sports Medicine using the wet bulb globe temperature (WBGT), but under lower threat levels using the heat index (HI). Football-specific thresholds based on clothing (full football uniform, practice uniform, or shorts) were also examined. The thresholds matched well with data from athletes wearing practice uniforms but poorly for those in shorts only. Too few cases of athletes in full pads were available to draw any broad conclusions. We recommend that coaches carefully monitor players, particularly large linemen, early in the pre-season on days with wet bulb globe temperatures that are categorized as high or extreme. Also, as most of the deaths were among young athletes, longer acclimatization periods may be needed.

Hypertension remains a common public health challenge because of its prevalence and increase in co-morbid cardiovascular diseases. Black males have disproportionate pathophysiological consequences of hypertension compared with any other group in the United States. Alterations in arterial wall compliance and autonomic function often precede the onset of disease. Accordingly, our purpose was to investigate whether differences exist in arterial compliance and autonomic function between young, healthy African-American males without evidence of hypertension and age- and gender-matched non-African-American males. All procedures were carried out noninvasively following rest. Arterial compliance was calculated as the integrated area starting at the well-defined nadir of the incisura of the dicrotic notch to the end of diastole of the radial artery pulse wave. Power spectral analysis of heart rate and blood pressure variability provided distributions representative of parasympathetic and sympathetic modulations and sympathovagal balance. Baroreflex sensitivity (BRS) was calculated using the sequence method. Thirty-two African-American and twenty-nine non-African-American males were comparable in anthropometrics and negative family history of hypertension. t-Tests revealed lower arterial compliance (5.8 +/- 2.4 vs. 8.6 +/- 4.0 mmHg. s; P = 0.0017), parasympathetic modulation (8.9 +/- 1.1 vs. 9.7 +/- 1.1 ln ms2; P = 0.0063), and BRS (13.7 +/- 7.3 vs. 21.1 +/- 8.5 ms/mmHg; P = 0.0007) and higher sympathovagal balance (2.9 +/- 3.2 vs. 1.5 +/- 1.1; P = 0.03) in the African-American group. In summary, differences exist in arterial compliance and autonomic balance in African-American males. These alterations may be antecedent markers of disease and valuable in the detection of degenerative cardiovascular processes in individuals at risk.

[Gender stereotypes in gynecology and obstetrics: obstacles for young male physicians?].

PubMed

Buddeberg-Fischer, Barbara

2003-10-01

Up to the mid 1990s, a 'feminization' of medicine took place that was especially pronounced in the field of gynecology. The present paper looks into the reasons for this change based on the literature and results from a study conducted by the author. In 2001, two thirds of the new qualifications in gynecology/obstetrics were awarded to women. The feminist movement has led to the emancipation of women and the assertion that women should be treated by female doctors only. Parallel to this development, gender roles also underwent a change: nowadays, the ideal woman or man is 'androgynous'. Young physicians are both highly instrumental and highly expressive. The increasing similarities between the sexes exert an influence on lifestyle and biographical planning. An increasing number of young physicians no longer prioritize their profession. Male physicians with high expressiveness are often family oriented and consciously refrain from choosing to specialize in gynecology/obstetrics because of the long hours and heavy workload. On the other hand, quite a few women physicians are more instrumental and prioritize their professional commitment. If more male physicians are not attracted into gynecology/obstetrics over the next few years, a process of 'horizontal segregation' could occur, with women physicians accomplishing the patient-focused work while their male colleagues take over the surgery and scientific part of the specialty. It is the very differences between the sexes, however, and the exchange between them, which allow a medical discipline to thrive.

American tackle football is the most popular high-energy impact sport in the United States, with approximately 9 million participants competing annually. Previous epidemiologic studies of football-related injuries have generally focused on specific geographic areas or pediatric age groups. Our study sought to examine patient characteristics and outcomes, including hospital charges, among athletes presenting for emergency department (ED) treatment of football-related injury across all age groups in a large nationally representative data set. Patients presenting for ED treatment of injuries sustained playing American tackle football (identified using International Classification of Diseases, Ninth Revision, Clinical Modification code E007.0) from 2010 to 2011 were studied in the Nationwide Emergency Department Sample. Patient-specific injuries were identified using the primary International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code and categorized by type and anatomical region. Standard descriptive methods examined patient demographics, diagnosis categories, and ED and inpatient outcomes and charges. During the study period 397363 football players presented for ED treatment, 95.8% of whom were male. Sprains/strains (25.6%), limb fractures (20.7%), and head injuries (including traumatic brain injury; 17.5%) represented the most presenting injuries. Overall, 97.9% of patients underwent routine ED discharge with 1.1% admitted directly and fewer than 11 patients in the 2-year study period dying prior to discharge. The proportion of admitted patients who required surgical interventions was 15.7%, of which 89.9% were orthopedic, 4.7% neurologic, and 2.6% abdominal. Among individuals admitted to inpatient care, mean hospital length of stay was 2.4days (95% confidence interval, 2.2-2.6) and 95.6% underwent routine discharge home. The mean total charge for all patients was $1941 (95% confidence interval, $1890-$1992) with substantial

Objectives Football has the highest sports participation (10.6%) in Ireland ahead of its Gaelic counterpart (3.9%). Research into injury incidence and patterns in Irish football is non-existent. The aim of this study was to conduct a prospective injury audit of League of Ireland (semiprofessional) footballers during the 2014 season (8 months, 28 games). Methods A total of 140 semiprofessional League of Ireland footballers were prospectively followed between March and November 2014. Data were collected in accordance with the international consensus on football injury epidemiology. Results The injury rate was 9.2/1000 hour exposure to football (95% CI 6.2 to 12.9, p<0.05). Players were at a higher risk of injury during a match compared with training (23.1 (95% CI 15.2 to 31.3) vs 4.8 (95% CI 2.2 to 7.7)/1000 hours, p<0.05). Injuries were most common during non-contact activity (54.6%), mainly running (30.9%), and occurred almost three times more often in the second half (56% vs 21%, p<05). Strains (50.1%) and sprains (20.3%) were the most common injury types, and the thigh region was injured most often (28.3%). Conclusions The prevalence of injury in League of Ireland football is similar to that of European professional football, although the incidence of injury is higher. The incidence of injury is in line with that of Dutch amateur football. PMID:29071112

ACTN3 R577X polymorphism and performance phenotypes in young Chinese male soldiers.

2012-01-01

Alpha-actinin-3 (ACTN3) is absent in 18% of healthy Caucasian individuals owing to homozygosity for a premature stop codon (X) at amino acid 577 (rs1815739). Previous studies have shown a strong association between ACTN3 genotype and human athletic performance. In a study of 452 young Chinese male soldiers, we examined the distribution of ACTN3 genotypes and alleles and analysed the association between ACTN3 genotypes and athletic performance. We found that the frequencies of the ACTN3 R577X genotype (RR 39.8%, RX 43.4%, and XX 16.8%) and R577X allele (R 61.5%, X 38.5%) in young Chinese males were not significantly different from those in Caucasians. We only observed a significant association (P = 0.025) between ACTN3 R577X genotypes and grip strength. Participants with the XX genotype displayed significantly lower handgrip strength than individuals with the RR genotype (P = 0.021), but the difference between XX and RX means (P = 0.258) and that between RR and RX means (P = 0.42) was not significant. We did not observe a strong association between the ACTN3 R577X genotypes and sprint phenotypes or endurance phenotypes. In conclusion, our results indicate that the ACTN3 R577X polymorphism is most strongly associated with grip strength in young Chinese male soldiers.

We investigated the impact of the colour of football outfits on localising football players and on the results of football matches. Two studies were conducted: an experimental study examining the effects of outfit colour on the assessment of the positions of computer-animated football players in a video set-up (study 1) and a retrospective study on professional football clubs' performances dependent on their outfit colours (study 2). The studies were conducted with 18 human volunteers aged 15-18 years (study 1) and league results from 10 professional European football teams over 17 years (1995-2013) (study 2). We analysed the number of correct assessments of the positions of virtual football players with different outfit colours (study 1) and analysed the relationship between match results and outfits' colours (study 2). Study 1 showed that the position of players wearing white outfits was better assessed in 5.2% of the trials compared to players wearing green outfits (P = 0.007). Study 2 showed that Manchester City conceded less goals against in away games in highly visible kits (r = 0.62; P = 0.024), while Newcastle United conceded less goals and won more points while playing in kits associated with low visibility (r = 0.63; P = 0.007; r = 0.50; P = 0.040, respectively). We conclude that the colour of football outfits affects evaluations of football players' positions on the field, with white tricots resulting in the best location assessment. The outfit colour may indirectly influence football match results, warranting more attention to the home and away shirts by team managers and football scientists.

Association between community socioeconomic characteristics and access to youth flag football.

2018-01-12

The American Academy of Pediatrics has recommended that opportunities for non-tackling American football (e.g., flag football) be expanded, given concerns about the risks of brain trauma from tackle football. This study tested the hypothesis that flag football would be more accessible in communities characterised by higher socioeconomic status residents. In July 2017, the locations of community-based organisations offering youth flag and tackle football for youth between the ages of 6 and 13 in two US states (Georgia and Washington) were aggregated (n=440). Organisations were coded in terms of the availability of tackle and/or flag football teams for youth at each year of age between 6 and 13. Multivariate logistic regression analyses were used to assess the odds of a community-based football organisation offering flag football, by community socioeconomic and demographic characteristics. In both states, communities with more educated residents were more likely to offer flag football for youth aged 6-12. For example, among 6 year-olds every 10% increase in the number of adult residents with a college education was associated with 1.51 times the odds of flag football availability (95% CI 1.22 to 1.86, P<0.001). These results suggest that youth living in communities characterised by low educational attainment are less likely than other youth to have the option of a lower contact alternative to tackle football. Relying on voluntary community-level adoption of lower contact alternatives to tackle football may result in inequitable access to such sport options. This may contribute to an inequitable burden of brain trauma from youth sport. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

This study employed a social-cognitive theoretical perspective to assess the interactions of behavioral, cognitive, and situational factors to understand better how young male sex workers (MSWs) entered the sex trade industry. As part of a larger project examining male escorts working for a single agency, MSWs (n = 38) were interviewed about their work and personal lives. Interviews were transcribed and analyzed thematically. As predicted by a social-cognitive perspective, results supported reciprocal influences of behavior and environment, environment and cognition, and behavior and cognition. MSWs developed more self-efficacy around sex work behaviors and more positive outcome expectations with experience; moral conflict and lack of attraction to clients limited MSWs’ self-efficacy. Key variables for sex work appeared to be cognitive in nature—mostly represented by a decreased commitment to normative social-sexual values, the specific nature of which may have varied by sexual orientation. Findings support the contention that social-cognitive theory can effectively model entry of young men into sex work. Social-cognitive theory provides a broad umbrella underneath which various explanations for male sex work can be gathered. PMID:22880726

Carter, Elizabeth A.; Westerman, Beverly J.; Hunting, Katherine L.

Context: A major challenge in the field of sports injury epidemiology is identifying the appropriate denominators for injury rates. Objective: To characterize risk of injury from participation in basketball, football, and soccer in the United States, using hours of participation as the measure of exposure, and to compare these rates with those derived using population estimates in the denominator. Design: Descriptive epidemiology study. Setting: United States, 2003–2007. Participants: People ages 15 years and older who experienced an emergency department–treated injury while playing basketball, football, or soccer. Main Outcome Measure(s): Rates of emergency department–treated injuries resulting from participation in basketball, football, or soccer. Injury rates were calculated for people ages 15 and older for the years 2003–2007 using the U.S. population and hours of participation as the denominators. The risk of injury associated with each of these sports was compared for all participants and by sex. Results: From 2003 through 2007, annual injury rates per 1000 U.S. population were as follows: 1.49 (95% confidence interval [CI] = 1.30, 1.67) in basketball, 0.93 (95% CI = 0.82, 1.04) in football, and 0.43 (95% CI = 0.33, 0.53) in soccer. When the denominator was hours of participation, the injury rate in football (5.08 [95% CI = 4.46, 5.69]/10 000 hours) was almost twice as high as that for basketball (2.69 [95% CI = 2.35, 3.02]/10 000 hours) and soccer (2.69 [95% CI = 2.07, 3.30]/10 000 hours). Conclusions: Depending on the choice of denominator, interpretation of the risk of an emergency department–treated injury in basketball, football, or soccer varies greatly. Using the U.S. population as the denominator produced rates that were highest in basketball and lowest in soccer. However, using hours of participation as a more accurate measure of exposure demonstrated that football had a higher rate of injury than basketball or soccer for both males and

Abstract Over the past decade, there has been significant debate regarding the effect of cumulative subconcussive head impacts on short and long-term neurological impairment. This debate remains unresolved, because valid epidemiological estimates of athletes' total contact exposure are lacking. We present a measure to estimate the total hours of contact exposure in football over the majority of an athlete's lifespan. Through a structured oral interview, former football players provided information related to primary position played and participation in games and practice contacts during the pre-season, regular season, and post-season of each year of their high school, college, and professional football careers. Spring football for college was also included. We calculated contact exposure estimates for 64 former football players (n=32 college football only, n=32 professional and college football). The head impact exposure estimate (HIEE) discriminated between individuals who stopped after college football, and individuals who played professional football (p<0.001). The HIEE measure was independent of concussion history (p=0.82). Estimating total hours of contact exposure may allow for the detection of differences between individuals with variation in subconcussive impacts, regardless of concussion history. This measure is valuable for the surveillance of subconcussive impacts and their associated potential negative effects. PMID:25603189

Head trauma and concussion in football players have recently received considerable media attention. Postmortem evidence suggests that accrual of damage to the brain may occur with repeated blows to the head, even when the individual blows fail to produce clinical symptoms. There is an urgent need for improved detection and characterization of head trauma to reduce future injury risk and promote development of new therapies. In this study we examined neurological performance and health in the presence of head collision events in high school football players, using longitudinal measures of collision events (the HIT(™) System), neurocognitive testing (ImPACT(™)), and functional magnetic resonance imaging MRI (fMRI). Longitudinal assessment (including baseline) was conducted in 11 young men (ages 15-19 years) participating on the varsity and junior varsity football teams at a single high school. We expected and observed subjects in two previously described categories: (1) no clinically-diagnosed concussion and no changes in neurological behavior, and (2) clinically-diagnosed concussion with changes in neurological behavior. Additionally, we observed players in a previously undiscovered third category, who exhibited no clinically-observed symptoms associated with concussion, but who demonstrated measurable neurocognitive (primarily visual working memory) and neurophysiological (altered activation in the dorsolateral prefrontal cortex [DLPFC]) impairments. This new category was associated with significantly higher numbers of head collision events to the top-front of the head, directly above the DLPFC. The discovery of this new category suggests that more players are suffering neurological injury than are currently being detected using traditional concussion-assessment tools. These individuals are unlikely to undergo clinical evaluation, and thus may continue to participate in football-related activities, even when changes in brain physiology (and potential brain

Should School Boards Discontinue Support for High School Football?

A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from sports injuries. In this paper, 3 experts also review the evidence about sports risks and discuss what is known and not known about the science and the ethics of high school football.

Descriptive, laboratory study. To compare the 3-D hip torques during a golf swing between young and senior healthy male amateur golfers. The secondary purpose was to compare the 3-D hip joint torques between the trail leg and lead leg. The generation of hip torques from the hip musculature is an important aspect of the golf swing. Golf is a very popular activity, and estimates of hip torques during the golf swing have not been reported. Twenty healthy male golfers were divided into a young group (mean ± SD age, 25.1 ± 3.1 years) and a senior group (age, 56.9 ± 4.7 years). All subjects completed 10 golf swings using their personal driver. A motion capture system and force plates were used to obtain kinematic and kinetic data. Inverse dynamic analyses were used to calculate 3-D hip joint torques of the trail and lead limbs. Two-way analyses of covariance (group by leg), with club-head velocity as a covariate, were used to compare peak hip torques between groups and limbs. Trail-limb hip external rotator torque was significantly greater in the younger group compared to the senior group, and greater in the trail leg versus the lead leg. When adjusting for club-head velocity, young and senior healthy male amateur golfers generated comparable hip torques during a golf swing, with the exception of the trail-limb hip external rotator torque. The largest hip torque found was the trail-limb hip extensor torque.

To investigate the effect of competitive football match congestion on hamstring strength and lower limb flexibility. Repeated measures. Elite male youth football. Fifteen male elite youth football players from the national football association centre of excellence were included (age = 15.81 ±0.65 years, height = 171.95 ±6.89 cm, weight = 65.93 ±7.53 kg). Hamstring strength and pain, ankle dorsiflexion, hip extension, knee extension and flexion range of motion. Hamstring strength was highest at baseline and significantly reduced at 24 (p = 0.001, mean difference -0.19 Nm/Kg, CI 95  -0.28, -0.1) and 48 h post-match 1 (p = 0.002, mean difference -0.16 Nm/Kg, CI 95  -0.25, -0.07). Strength recovered by match day 2 before significantly reducing again 24 h post-match 2 (p = 0.012, mean difference -0.17 Nm/Kg, CI 95  -0.29, -0.04). Pain was lowest at baseline and increased in the post-match periods (p < 0.05) with standardised effect sizes ranging from 0.07 to 0.42. Passive knee flexion range decreased post-match (p < 0.01) with mean differences of 1.5°-2.7°. The other flexibility measures remained unaffected by match play. Isometric hamstring strength and pain can be considered for inclusion in-season to monitor player's post-match hamstring recovery characteristics during congested match fixtures.

The relative age effect is an uneven distribution of birth date favouring subjects born in the initial months of a selection year. This study compared the birth-date distributions between several subgroups of Basque football players to identify whether the relative age effect is influenced by age and/or skill level. The study comprised 13,519 players including 114 senior professionals from the Spanish league's AC Bilbao over 21 seasons; over the season 2005-2006, it comprised elite youth (n=189) from the same club's academy; regional youth (n=4382) U11-U14 locally federated players; school youth (n=8834) U10-U11 locally registered school district players. Differences between the observed and expected birth-date distributions were tested based on data from the general Basque male population. Significant chi-square values were followed up by calculating odds ratios and 95% confidence intervals (CI) for the quartile and half-year distributions to examine subgroup differences in the relative age effect. Birth-date distributions of all groups of players showed a significant bias towards early birth in the selection year compared with the reference population (senior, chi-2(3) = 24.4, P < 0.001; elite youth, chi-2(3) = 59.1, P < 0.001; regional youth, chi-2(3) = 41.4, P < 0.001; school youth, chi-2(3) = 40.9, P < 0.001). Between-group comparison revealed that the relative age effect incidence progressively increased with a higher level of involvement in youth football. This bias represents a significant loss of potential youth football talent.

The injuries sustained by the boys at one English public school have been recorded and analysed by age, experience, position, phase, duration of the game and of the season. Few injuries have been serious. Detailed reference is made to concussion, injuries from collapsed scrums and injuries of the cervical spine. The paper emphasises that the tackle leads to most injuries. This paper presents the Rugby football injuries sustained by the boarders of Rugby School in the four seasons 1980-1983. The injury rate was 194 per 10,000 player hours, compared with the rate of 198 per 10,000 player hours for the thirty seasons 1950-1979 (Sparks, 1981). Tables I-VI list the injuries by different criteria. Table VII lists the sites of injury; Table VIII the time off Rugby football after injury; Table IX lists some of the more important injuries; Table XI summarises the playing results of the various school teams; Table XIII compares some of the Rugby School figures with those recorded in the Accident and Emergency Department of Christchurch Hospital during the 1979 New Zealand Rugby football season (Inglis and Stewart, 1981); Table XIV records information on three aspects of Rugby football that have occasioned much recent concern, viz:--Time off playing after concussion, injuries caused by collapsed scrums and neck injuries.

This paper draws on recent research to explore the changing cultures of racism in English football. Starting from a critical analysis of key themes in the literature on football it seeks to show that existing analytical frameworks need to be reworked if they are going to adequately account for the complex forms through which racism is expressed in contemporary football cultures. In the course of this analysis we question some of the ways in which the issue of racism in football is collapsed into broader accounts of 'hooliganism' and other forms of violence among football fans. From this starting point the paper draws on some elements of our empirical research in order to outline an alternative way of framing the issues of racism and multicultrralism in football.

Background: Nowadays, doping is an intricate dilemma. Football is the nationally popular sport in Iran. On the other hand, doping is a serious health hazard sport faces today. Studies dealing with athletes’ knowledge, attitudes and behavior concerning doping in football are scarce. Objectives: Therefore, we aimed to investigate the knowledge and attitudes toward doping among the football coaches and players. Patients and Methods: In a cross sectional study, 375 participants (239 football players and 136 coaches) were studied. A specially made questionnaire was applied. In this study, football teams of different provinces of the country were selected by randomized clustered sampling and questionnaires were distributed among coaches and players. Results: Knowledge of football coaches and players in three categories of doping definitions, recognition of prohibited drugs and side effects of anabolic steroids was poor or moderate in 45.3%, 88.5% and 96.5%, respectively. Conclusions: Football players and coaches have poor knowledge about doping in Iran. Moreover, they believe in some inappropriate myths without any scientific or rational basis.It seems necessary to design a comprehensive educational program for all of the athletes and coaches in Iran.

The current review explores the complex paths that can lead to adolescent and young adult males becoming sexually abusive. Because sexual abuse is an ongoing issue in our society that is often oversimplified, this article distinguishes between the various risk factors that predict sexually abusive behavior and types of sex offenders, particularly recidivistic offenders. It is imperative to focus on adolescents and young adults who sexually abuse because they represent a particularly important intervention point in preventing sexual abuse in comparison to older age groups and address the importance of differentiating among youths who sexually abuse, particularly between one-time offenders and recidivistic offenders. Implications for addressing these differences are discussed.

Limited ranges of motion (ROM) have been considered as a primary risk factor for some football injuries, but only a few studies have analysed differences in lower extremity joints. The main purposes were (a) to describe the lower extremity ROM profile in professional football players; and (b) to examine differences between goalkeepers and outfield players. 82 professional male football players from 4 teams were measured in the 2013 pre-season. Measures of passive hip (flexion with knee flexed [PHFKF] and extended [PHFKE], extension [PHE], abduction [PHA], external [PHER] and internal [PHIR] rotation), knee (flexion [PKF]) and ankle (dorsiflexion with knee flexed [ADFKF] and extended [ADFKE]) ROMs were taken. Magnitude-based inferences exploring differences between player position and limb were made. 46% of all participants showed restricted PHFKE and/or around 30% showed restricted ADFKF ROM values. Contrarily, most players reported normal PHFKF, PHE, PHIR and PHER as well as PKF ROM scores with percentage values close to 100%. Bilateral meaningful differences for PHA, PHIR and PHER were found in approximately 30% of outfield players and goalkeepers. Statistical analysis found trivial differences between players for PHFKE, PHE, PHIR, PHER, ADFKE and ADFKF. However, moderate differences between players were found for PHFKF, PHA and PKF, with goalkeepers demonstrating higher values than outfield players. The findings of this study reinforce the necessity of prescribing exercises aimed at improving PHFKE and ADFKF ROM within everyday football training routines. In addition, as some bilateral deficits were observed, unilateral training should be considered where appropriate.

than 1 week, one third resulted in an absence between 1 and 4 weeks, and 10 to 15 % of all injuries were severe. Separate data for players under the age of 11 years are almost absent. Maturation status seems to have an influence on injury characteristics, although evidence is not conclusive at this time. Three main areas seem to be of particular relevance for future prevention research in young football players: (1) the substantial number of severe contact injuries during matches, (2) the high number of fractures in younger players, and (3) the influence of maturation status and growth spurts.

Objectives: To examine several issues related to drug use in English professional football. More particularly the project sought to gather data on: players' use of permitted supplements (mineral and vitamin pills and creatine); whether they sought advice, and if so from whom, about their use of supplements; their experience of and attitudes towards drug testing; their views on the extent of the use of banned performance enhancing and recreational drugs in football; and their personal knowledge of players who used such drugs. Methods: With the cooperation of the Professional Footballers Association (PFA), reply paid postal questionnaires were delivered to the home addresses of all 2863 members of the PFA. A total of 706 questionnaires were returned, a response rate of just under 25%. Results: Many players use supplements, although almost one in five players does so without seeking qualified professional advice from anyone within the club. Blood tests are rarely used to monitor the health of players. One third of players had not been tested for drugs within the preceding two years, and 60% felt that they were unlikely to be tested in the next year. The use of performance enhancing drugs appears to be rare, although recreational drugs are commonly used by professional footballers: 6% of respondents indicated that they personally knew players who used performance enhancing drugs, and 45% of players knew players who used recreational drugs. Conclusions: There is a need to ensure that footballers are given appropriate advice about the use of supplements in order to minimise the risk of using supplements that may be contaminated with banned substances. Footballers are tested for drugs less often than many other elite athletes. This needs to be addressed. The relatively high level of recreational drug use is not reflected in the number of positive tests. This suggests that many players who use recreational drugs avoid detection. It also raises doubts about the ability of

Recently, economic theory has been expanded to incorporate emotions, which have been assumed to play an important role in financial decisions. The present study illustrates this by showing a connection between the sports performance of popular national football teams (Besiktas, Fenerbahce, and Galatasaray) and performance of the Turkish economy. Specifically, a significant positive association was found between the success of three major professional Turkish football teams and the exchange rate of the Turkish lira against the U.S. dollar. The effect of the football success of several Turkish football teams on the exchange rate of the Turkish lira was examined using the simultaneous multiple regression model with predictor measures of wins, losses, and ties for different combinations of teams to predict the depreciation rate of the Turkish lira between the years 1987 and 2003. Wins by Turkish football teams against foreign (non-Turkish) rivals increased with exchange rate depreciation of the Turkish lira against the U.S. dollar.

Cervical spinal cord injuries have been the most common catastrophic football injury and the second leading direct cause of death attributable to football skills. This study looks at the 25-year (1977-2001) experience with catastrophic neck injuries and examines not only the incidence but also the cause of injury and variables that have either increased or decreased these injuries. Data were collected on a national level from all organized football programs, including public school, college, professional, and youth programs, through personal contact and questionnaires on each catastrophic football injury. Funded by the National Collegiate Athletic Association, the National Federation of State High School Associations, and the American Football Coaches Association, data were collected by the National Center for Catastrophic Sports Injury Research, University of North Carolina at Chapel Hill (Frederick O. Mueller, Director, and Robert C. Cantu, Medical Director). Teaching the fundamental techniques of the game, equipment standards, and improved medical care both on and off the playing field have led to a 270% reduction in permanent spinal cord injury from a peak of 20 per year during the period 1971 to 1975 to 7.2 per year during the past 10 years. The type of injury, activity at the time of injury, level of play, and whether the injury was incurred in a game or practice are presented. On the basis of the data, recommendations are given for reducing catastrophic cervical spine injury in football.

Young men who have sex with men are at high risk for HIV, and most new HIV infections occur in serious relationships. This pilot study assessed the feasibility, acceptability and preliminary efficacy of the 2GETHER couples-based HIV prevention and relationship education intervention for young same-sex male couples. We enrolled 57 young male couples (N = 114) into a four-session hybrid group and individual intervention. We assessed acceptability via post-session surveys and exit interviews, and we examined preliminary efficacy at a two week posttest. The vast majority of participants (93%) reported exclusively positive impressions of 2GETHER, and all components received high mean ratings. We observed decreases in HIV risk behavior, increases in information, motivation and behavioral skills related to HIV prevention, and improvement in relationship investment between pretest and posttest. Integrating relationship education and sexual health programming may be an effective way to reduce HIV transmissions in young male couples.

Body dimensions and body composition of children participating in artistic activities, such as gymnastics and many types of dancing, are important factors in performance improvement. The present study aimed to determine the reliability of a series of selected anthropometric measurements in young male and female gymnasts. Segment lengths, body breadths, circumferences, and skinfold thickness were measured in 20 young gymnasts by the same experienced examiner, using portable and easy-to-use instruments. All parameters were measured twice (test-retest) under the same conditions within a week's period. The high intra-class correlation coefficient (ICC) values ranging from 0.87 to 0.99, as well as the low coefficient of variation (CV) values (<5.3%), affirmed that the selected measurements were highly reliable. The technical error of measurement (TEM) values for lengths and breadths were 0.15 to 0.80 cm, for circumferences 0.22 to 1 cm, and for skinfold thickness 0.33 to 0.58 mm. The high test-retest ICC and the low CV and TEM values confirmed the reliability of all anthropometric measurements in young artistic gymnasts. Therefore, these measurements could contribute to further research in this field of investigation, helping to monitor young artistic gymnasts' growth status and identify specific characteristics for increased performance in this sport.

Despite cultural and religious prohibitions against premarital heterosexual relationships and intimacy, some recent evidence suggests some rise in premarital heterosexual interactions and relationships among young people. On the other hand, although HIV in Iran is a concentrated epidemic and mainly reported among high risk groups such as injecting drug users (IDUs), but there are evidences that the mode of transmission is shifting towards sexual contacts. This trend has caused concern among health policy makers in terms of prevention of STDs and HIV/AIDS particularly, among young people. This paper was prepared with the aim of highlighting how gender contributes to variation in reproductive health needs and conduct of young people in Iran. This paper is based on a secondary analysis and compares comparable reproductive beliefs and conducts of women and men based on the data of two surveys conducted in Tehran in 2002 and 2005. A survey among 1385 adolescent males and another survey among 1743 female undergraduate students in four multidisciplinary universities in Tehran. Both surveys used anonymous self-administered questionnaires. To make the two samples comparable, the data of unmarried female university undergraduate students who resided in Tehran were merged with the data of adolescent male students who intended to pursue higher education. Common variables of the two surveys were identified, homogenized, merged and analysed. Reproductive health knowledge among male adolescents was poor compared to that of their female peers. Although premarital friendships were moderately acceptable from view points of both males and females, the majority were against premarital sex, particularly among female participants. There were evidences of gender-based double standards in perceptions of premarital sexuality among both males and females; particularly, it was stronger among males than females. Male adolescents reported earlier and greater experiences of premarital

Football (soccer) is endorsed as a health-promoting physical activity worldwide. When football programs are introduced as part of general health promotion programs, equal access and limitation of pre-participation disparities with regard to injury risk are important. The aim of this study was to explore if disparity with regard to parents' educational level, player body mass index (BMI), and self-reported health are determinants of football injury in community-based football programs, separately or in interaction with age or gender. Four community football clubs with 1230 youth players agreed to participate in the cross-sectional study during the 2006 season. The study constructs (parents' educational level, player BMI, and self-reported health) were operationalized into questionnaire items. The 1-year prevalence of football injury was defined as the primary outcome measure. Data were collected via a postal survey and analyzed using a series of hierarchical statistical computations investigating associations with the primary outcome measure and interactions between the study variables. The survey was returned by 827 (67.2%) youth players. The 1-year injury prevalence increased with age. For youths with parents with higher formal education, boys reported more injuries and girls reported fewer injuries than expected; for youths with lower educated parents there was a tendency towards the opposite pattern. Youths reporting injuries had higher standardized BMI compared with youths not reporting injuries. Children not reporting full health were slightly overrepresented among those reporting injuries and underrepresented for those reporting no injury. Pre-participation disparities in terms of parents' educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. When introduced as a general health promotion, football associations should adjust community-based youth

Motor and cognitive growth in children may be influenced by football practice. Therefore the aim of this study was to assess whether a Football Training Program taken over 6 months would improve motor and cognitive performances in children. Motor skills concerned coordinative skills, running, and explosive legs strength. Cognitive abilities involved visual discrimination times and visual selective attention times. Forty-six children with chronological age of ∼9.10 years, were divided into two groups: Group 1 (n = 24) attended a Football Exercise Program and Group 2 (n = 22) was composed of sedentary children. Their abilities were measured by a battery of tests including motor and cognitive tasks. Football Exercise Program resulted in improved running, coordination, and explosive leg strength performances as well as shorter visual discrimination times in children regularly attending football courses compared with their sedentary peers. On the whole these results support the thesis that the improvement of motor and cognitive abilities is related not only to general physical activity but also to specific ability related to the ball. Football Exercise Programs is assumed to be a “natural and enjoyable tool” to enhance cognitive resources as well as promoting and encouraging the participation in sport activities from early development.

A decline in physical capacity takes place with increasing age that negatively affects overall physical function including work ability and the ability to perform typical activities of daily living (ADL). The overall aim of the present study was to determine the neuromuscular adaptations to long-term (1 year) football and strength training in older untrained adults, and to assess the concurrent effect on functional ADL capacity. Twenty-seven healthy elderly males (68.2 ± 3.2 years) were randomly assigned to 12 months of either recreational football training (FT: n = 10), strength training (ST: n = 9) or served as inactive controls (CON: n = 8). Recreational football training consisted of small-sided training sessions whereas strength training consisted of high intensity exercises targeting the lower extremity and upper body. Maximal thigh muscle strength and rate of force development (RFD) were assessed with isokinetic dynamometry, while postural balance and vertical jumping performance were evaluated using force plate analysis. Furthermore, functional ability was evaluated by stair-ascent and chair-rising testing. A total of nine, nine and seven participants from FT, ST and CON, respectively, were included in the analysis. Both exercise regimens led to substantial gains in functional ability, evidenced by 24 and 18 % reduced stair-ascent time, and 32 and 21 % increased chair-rising performance in FT and ST, respectively (all P < 0.05). Long-term strength training led to increased concentric (14 %; P < 0.01) and isometric (23 %; P < 0.001) quadriceps and isometric hamstring strength (44 %; P < 0.0001), whereas football training mainly resulted in enhanced hamstring strength (18 %, P < 0.05) and RFD (89 %, P < 0.0001). Long-term (1 year) strength training led to increased quadriceps and hamstring strength, whereas the adaptations to football training mainly included enhanced strength and rapid force capacity of the hamstring muscles

The present study aimed at analyzing the efficacy of a 6-month football training program compared with a standard exercise program on health and fitness parameters in overweight children. The study design was a 6-month, two-arm, parallel-group randomized trial. Twenty-two overweight children were randomly assigned to two groups (age=10.8+/-1.2 years, height=1.56+/-0.08 m, weight= 65.1+/-11.4 kg). One group conducted a football training program, and the other group an established standard sports program. Both interventions took place three times per week from mid-May to mid-November. Before, after 3 months and after the training period, comprehensive testing was conducted: anthropometric characteristics, cycling ergometry, psychometric monitoring as well as several motor ability tests. Maximal performance capacity increased and submaximal heart rate during cycling ergometry decreased significantly. Several motor skills as well as self-esteem also improved considerably. Body composition and other psychometric variables remained nearly unchanged. No relevant differences were observed between both exercise programs. It can be concluded that a 6-month football training is as efficacious in improving the physical capacity, health-related fitness parameters and self-esteem of overweight children as a standard exercise program. These results provide further evidence that playing football has significant health effects.

The purpose of this study was to evaluate the anthropometric characteristics and fitness levels of elite level under 18 (U-18) Gaelic football players to establish normative centile scores for selected fitness parameters and to compare the physical and fitness characteristics relative to each playing position. A total of 265 male U-18 Gaelic football players (age: 16.96 ± 0.7 years; height: 178.11 ± 6.27 cm; weight: 72.07 ± 8.68 kg) participated in the study. According to positional roles, players were categorized as goalkeepers (n = 13), defenders (n = 113), midfielders (n = 30), and forwards (n = 109). Height and weight were measured, and skinfolds were taken before participants sequentially performed a sit and reach test (S&R), countermovement jump (CMJ), standing long jump (SLJ), 5- and 20-m speed test, and the Yo-Yo Intermittent Recovery Test Level 1 (YYIRT1). The percentage body fat was higher (p < 0.01) in goalkeepers than the other playing positions. Goalkeepers had a higher body mass index than defenders (p < 0.05) and forwards (p < 0.01). Midfielders and goalkeepers were taller (p < 0.01) and heavier (p < 0.01) than defenders and forwards. The total distance covered in the YYIRT1 was significantly lower (p < 0.01) in goalkeepers than the other playing positions. There was no significant positional difference in the performance scores in the S&R test, CMJ, SLJ, and 5- and 20-m running speed. The study findings indicate minimal differences in the anthropometric and physiological characteristics between playing positions in elite youth level Gaelic football players. The norm-referenced percentile scores will enable conditioning coaches to benchmark elite performance and design training programs.

Background: Determining somatic models and profiles in young athletes has recently become a fundamental element in selecting basketball playing positions. The aim of this study was to assess the relationship between the body build of young and adult elite male basketball players at different playing positions. Methods: Participants consisted of 35 young (age: 14.09 ± 0.30 years, n = 35) and 35 adult professional basketball players (age: 24.45 ± 5.40 years, n = 35) competing in elite leagues. The anthropometric characteristics assessed included body mass, body height, skinfolds, somatotypes, girths, and breadths. Results: The centers in both age groups were significantly taller and heavier (p < 0.001) compared to forwards and guards. The greatest difference between categories were in the guards’ personal height (from 169.36 to 186.68 = 17.32 cm). The guards from the professional team were closest in height to the forwards (difference = 7.17 cm) compared to young players where the difference between guards and forwards was 13.23 cm. Young competitors were more ectomorphic (2.12-3.75-4.17), while professional players were more mesomorphic (2.26-4.57-3.04). Significant criteria for center selection at professional level seems to be personal height and arm span ratio. Conclusions: The results indicate that the selection for basketball playing positions should include the analysis of body height and mass, shoulder breadth, humerus breadth, femur breadth and specifically for centers the difference between personal the height and arm span.

Kirsch, Jacob M; Burrus, M Tyrrell; Bedi, Asheesh

2018-03-01

Professional football quarterbacks are at particular risk for upper extremity injuries due to the physical demands of their position coupled with the inherent risks associated with professional football. This review sought to evaluate current clinical literature to better characterize the injury profile unique to this athletic population. Shoulder injuries are the most prevented upper extremity injury among professional football quarterbacks. The quarterback position is disproportionately impacted by shoulder injuries when compared to professional athletes at other positions. Moreover, contrary to other professional throwing athletes, the majority of upper extremity injuries in the professional quarterback result from direct contact as opposed to the throwing motion. The injury profile among professional quarterbacks is unique compared to other positions and other overhead professional throwing athletes. Overall, a paucity of high quality clinical evidence exists to support the management of injuries in this elite population.

Although there are enough studies concerning the kinanthropometric attributes of players of sports such as football, basketball, or volleyball in Turkey, there are not enough studies on the same for combat sports. Hence, our aim is to assess the kinanthropometric attributes of different combat sports like karate, taekwondo, judo and kickboxing. The present study included 48 national level male athletes from four different combat sports (age, 20.3 (3.19) years; number of years playing the sport, 8.33 (4.59); height, 174.3 (7.15) cm; weight, 67.35 (10.55 kg). Skinfold thickness was measured with a skinfold caliper (Holtain Ltd., UK), and Yuhazs formula was used to calculate the body fat percentage. Somatotype assessment was carried out with a computer program (Sweat Technology Trial Version, South Australia). Width measurements were obtained with a slide caliper (HLT-100, Holtain Ltd.), and girth measurements were obtained with a non-flexible tape measure. The data obtained were analyzed with the computer program SPSS 17.0 in terms of the SD. The findings were as follows: body mass index (BMI), 22.00 (2.66) kg/m2; body fat percentage, 12.20% (3.07%); endomorphic component, 2.9 (1.30); mesomorphic component, 4.25 (1.30); and ectomorphic component, 3.10 (1.30). The cormic index was 51.99% (1.88%); Monourier index, 92.39% (4.47%); Acromio-iliac index, 60.87% (6.61%); Martine index, 6.29% (0.70%); Biacromial index, 22.58% (0.99%); and hip index, 13.91% (0.86%). The mesomorphic component was found to be dominant in our study. Although BMIs were found to be normal, body fat percentages were low. According to body proportions, the athletes who participated in this study had wide shoulders, narrow hips, and medium-sized trunks.

By maintaining phosphate and calcium homeostasis, vitamin D is critical for bone health and possibly physical performance. Hence, vitamin D is important to athletes. Few studies have investigated vitamin D levels in relation to fractures and performance in athletes, and no published study has included a multiracial sample of professional American football players. To assess vitamin D levels, including the prevalence of vitamin D deficiency/insufficiency, in professional American football players and to evaluate the association of vitamin D levels with race, fracture history, and the ability to obtain a contract position, which may be a marker for athletic performance. Cohort study; Level of evidence, 3. Serum vitamin D levels of 80 professional football players from a single team in the National Football League were obtained during the 2011 off-season (mean age, 26.5±3.7 years; black, n=67 [84%]). These levels were used to compare injury reports from the 2011-2012 and 2012-2013 seasons. Statistical analyses were performed to test if vitamin D levels were related to race, fracture history, and the ability to obtain a contract position. Mean vitamin D level was 27.4±11.7 ng/mL, with significantly lower levels for black players (25.6±11.3 ng/mL) versus white players (37.4±8.6 ng/mL; F 1,78=13.00, P=.001). All athletes who were vitamin D deficient were black. When controlling for number of professional years played, vitamin D levels were significantly lower in players with at least 1 bone fracture when compared with no fractures. Players who were released during the preseason because of either injury or poor performance had significantly lower vitamin D levels than did players who played in the regular season. Black professional football players have a higher rate of vitamin D deficiency than do white players. Furthermore, professional football players with higher vitamin D levels were more likely to obtain a contract position in the National Football League

Football players wear boots of varying cleat designs with some preferring the bladed cleats while others opting for the conventional studded cleats. The current study compares biomechanically the boots with differing cleat designs and their effect on feet, if any. Twenty-nine healthy male volunteers were recruited from amateur football teams. They were asked to perform three trials each of two activities: a straight run and a run cutting at a 60° angle wearing bladed and studded Adidas®-F series boots on artificial turf. Plantar pressure values were recorded using the Pedar®-X in-shoe pressure measuring device. Peak pressure and pressure-time integral were analysed over 11 clinically relevant areas under the foot. While the in-shoe pressure and pressure-time integral were higher under the medial half of the foot with studded boots, they were higher under the lateral half of the foot with the bladed design. The studded boots can be considered safer as the pressure distribution across the foot and the pattern of centre of pressure progression mimicked the normal motif, whereas the bladed boots could potentially be deemed relatively more harmful due to the unnatural increased loading under the lateral half of the foot, predisposing the foot to injuries.

To determine if pre-season adductor squeeze test and HAGOS function, sport and recreation subscale scores can identify Gaelic football players at risk of developing groin injury. Prospective study. Senior inter-county Gaelic football team. Fifty-five male elite Gaelic football players (age = 24.0 ± 2.8 years, body mass = 84.48 ± 7.67 kg, height = 1.85 ± 0.06 m, BMI = 24.70 ± 1.77 kg/m 2 ) from a single senior inter-county Gaelic football team. Occurrence of groin injury during the season. Ten time-loss groin injuries were registered representing 13% of all injuries. The odds ratio for sustaining a groin injury if pre-season adductor squeeze test score was below 225 mmHg, was 7.78. The odds ratio for sustaining a groin injury if pre-season HAGOS function, sport and recreation subscale score was < 87.5 was 8.94. Furthermore, for each additional point on the numerical rating scale pain rating during performance of the adductor squeeze test, the odds of groin injury increased by 2.16. This study provides preliminary evidence that pre-season adductor squeeze test and HAGOS function, sport and recreation subscale scores can be used to identify Gaelic football players at risk of developing groin injury.

Two schools in Khayelitsha township, South Africa. 370 children making up two intervention groups (Grade 6: 125; Grade 7: 131) and one control group (Grade 7: 114). Eleven 90 min sessions, each divided into two 45 min halves of Play Football (football skills) and Play Fair (health issues), each session focused on one specific health risk factor. Health knowledge using a 20-item questionnaire; coaches' attitudes towards their training programme using a 10-item questionnaire and children's attitudes towards the health education programme using a six-item questionnaire. Children in the Grade 7 intervention group showed significant (p<0.05) increases in the proportion of correct responses for nine of the 20 health knowledge questions postintervention, and these increases were maintained at 3 months postintervention. The Grade 6 intervention group showed significant increases in the proportion of correct responses for 15 of the 20 health knowledge questions postintervention. The Grade 7 control group showed a significant increase in the proportion of correct responses to one of the 20 health knowledge questions post-Play Football sessions and nine of 20 questions post-Play Fair sessions. Over 90% of the children provided positive attitude responses to the health-education programme. The programme demonstrated that it was possible to implement a football-based health-education programme for children in Africa that achieved significant increases in health knowledge and that was also well received by participants.

The issues of modeling asscoiation football prediction model has become increasingly popular in the last few years and many different approaches of prediction models have been proposed with the point of evaluating the attributes that lead a football team to lose, draw or win the match. There are three types of approaches has been considered for predicting football matches results which include statistical approaches, machine learning approaches and Bayesian approaches. Lately, many studies regarding football prediction models has been produced using Bayesian approaches. This paper proposes a Bayesian Networks (BNs) to predict the results of football matches in term of home win (H), away win (A) and draw (D). The English Premier League (EPL) for three seasons of 2010-2011, 2011-2012 and 2012-2013 has been selected and reviewed. K-fold cross validation has been used for testing the accuracy of prediction model. The required information about the football data is sourced from a legitimate site at http://www.football-data.co.uk. BNs achieved predictive accuracy of 75.09% in average across three seasons. It is hoped that the results could be used as the benchmark output for future research in predicting football matches results.

Use of the male condom by heterosexual adolescents and young people: literature review.

PubMed

East, Leah; Jackson, Debra; O'Brien, Louise; Peters, Kathleen

2007-07-01

This paper is a report of a literature review to explore issues influencing condom use in heterosexual adolescents and young people. Sexually transmitted infections (STIs) are a major international health issue and adolescents and young people are particularly vulnerable. Efforts to address the rapid spread of STIs have largely focused on promoting the use of condoms as a protective 'safer sex' measure. However, use of the male condom is still inconsistent and the incidence of STIs continues to increase. A search of the literature using EBSCO Host databases was undertaken in 2006, with a focus on women, young people, condoms and STIs. Papers published in English from 1992 to 2006 were sought. Only research papers are included in this review. Factors impeding decisions to use protection by young people include lack of knowledge about prevalence of STIs, ambiguity around contraception and safer sex practices, and the difficulty faced by young women in particular in negotiating safer sex. The notion of romantic love confounds the assessment of risk and can render young people, particularly young women, ineffective in negotiating safer sex practices. Adolescents and young adults are particularly vulnerable in relation to STIs. There is a need to ensure that accurate messages are delivered about safer sex and contraception to this very vulnerable group. Furthermore, it is important to recognize that romantic love comprises strong emotions that have a role in decision-making and options for reducing personal-health risk during sexual activity.

Numerous studies have reported on the thermoregulation and hydration challenges athletes face in team and individual sports during exercise in the heat. Comparatively less research, however, has been conducted on the American Football player. Therefore, the purpose of this article is to review data collected in laboratory and field studies and discuss the thermoregulation, fluid balance, and sweat losses of American Football players. American Football presents a unique challenge to thermoregulation compared with other sports because of the encapsulating nature of the required protective equipment, large body size of players, and preseason practice occurring during the hottest time of year. Epidemiological studies report disproportionately higher rates of exertional heat illness and heat stroke in American Football compared with other sports. Specifically, larger players (e.g., linemen) are at increased risk for heat ailments compared with smaller players (e.g., backs) because of greater body mass index, increased body fat, lower surface area to body mass ratio, lower aerobic capacity, and the stationary nature of the position, which can reduce heat dissipation. A consistent finding across studies is that larger players exhibit higher sweating rates than smaller players. Mean sweating rates from 1.0 to 2.9 L/h have been reported for college and professional American Football players, with several studies reporting 3.0 L/h or more in some larger players. Sweat sodium concentration of American Football players does not seem to differ from that of athletes in other sports; however, given the high volume of sweat loss, the potential for sodium loss is higher in American Football than in other sports. Despite high sweating rates with American Football players, the observed disturbances in fluid balance have generally been mild (mean body mass loss ≤2 %). The majority of field-based studies have been conducted in the northeastern part of the United States, with limited

Background Football (soccer) is endorsed as a health-promoting physical activity worldwide. When football programs are introduced as part of general health promotion programs, equal access and limitation of pre-participation disparities with regard to injury risk are important. The aim of this study was to explore if disparity with regard to parents’ educational level, player body mass index (BMI), and self-reported health are determinants of football injury in community-based football programs, separately or in interaction with age or gender. Methodology/Principal Findings Four community football clubs with 1230 youth players agreed to participate in the cross-sectional study during the 2006 season. The study constructs (parents’ educational level, player BMI, and self-reported health) were operationalized into questionnaire items. The 1-year prevalence of football injury was defined as the primary outcome measure. Data were collected via a postal survey and analyzed using a series of hierarchical statistical computations investigating associations with the primary outcome measure and interactions between the study variables. The survey was returned by 827 (67.2%) youth players. The 1-year injury prevalence increased with age. For youths with parents with higher formal education, boys reported more injuries and girls reported fewer injuries than expected; for youths with lower educated parents there was a tendency towards the opposite pattern. Youths reporting injuries had higher standardized BMI compared with youths not reporting injuries. Children not reporting full health were slightly overrepresented among those reporting injuries and underrepresented for those reporting no injury. Conclusion Pre-participation disparities in terms of parents’ educational level, through interaction with gender, BMI, and self-reported general health are associated with increased injury risk in community-based youth football. When introduced as a general health promotion

Football players are subjected to repetitive impacts that may lead to brain injury and neurologic dysfunction. Knowledge about head impact exposure (HIE) and consequent neurologic function among youth football players is limited. This study aimed to measure and characterize HIE of youth football players throughout one season and explore associations between HIE and changes in selected clinical measures of neurologic function. Twenty-two youth football players (11-13 yr) wore helmets outfitted with a head impact telemetry (HIT) system to quantify head impact frequency, magnitude, duration, and location. Impact data were collected for each practice (27) and game (9) in a single season. Selected clinical measures of balance, oculomotor performance, reaction time, and self-reported symptoms were assessed before and after the season. The median individual head impacts per practice, per game, and throughout the entire season were 9, 12, and 252, respectively. Approximately 50% of all head impacts (6183) had a linear acceleration between 10g and 20g, but nearly 2% were greater than 80g. Overall, the head impact frequency distributions in this study population were similar in magnitude and location as in high school and collegiate football, but total impact frequency was lower. Individual changes in neurologic function were not associated with cumulative HIE. This study provides a novel examination of HIE and associations with short-term neurologic function in youth football and notably contributes to the limited HIE data currently available for this population. Whereas youth football players can experience remarkably similar head impact forces as high school players, cumulative subconcussive HIE throughout one youth football season may not be detrimental to short-term clinical measures of neurologic function.

Facial fractures in football: incidence, site, and mechanism of injury.

Football injuries are responsible for many of the maxillofacial injuries sustained during sporting activities. In the Australian Capital Territory (ACT), the four major types of Australian football are played in large numbers and up to a high standard. Our objective was to analyse maxillofacial fractures that were sustained during rugby league, rugby union, Australian rules, and soccer matches. We retrospectively studied 134 patients with maxillofacial fractures during the five-year period 2010-14. All patients were assessed and treated at Canberra Hospital, the major trauma centre in the ACT. Data collected from patients' records included type of football, age, sex, mechanism of injury, site of injury, and treatment. The number of people registered to play was obtained from each football governing body to find out the incidence of fractures. League had the highest incidence of facial fractures, followed by union, Australian rules, and soccer. High speed and high collision football (league and union) had a higher rate of mandibular fractures than high speed and low contact football (Australian rules and soccer) (n=43, 45% compared with n=7, 21%). Australian rules and soccer had a higher incidence of midface fractures than league and union (n=26, 79%, compared with n=52, 55%). Clash of heads was the leading cause of fractures. Collisions against other players' shoulders and forearms were more likely to cause mandible fractures. Ninety-four patients (70%) required surgical intervention. Football-related maxillofacial fractures occur regularly, and different types of football have predictable patterns of injury. Padding of the heads and elbows of players may reduce the number and seriousness of facial fractures. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

Is perceived parental monitoring associated with sexual risk behaviors of young Black males?☆☆☆

2015-01-01

This study determined whether perceived parental monitoring is associated with any of twelve selected outcomes related to sexual risk behaviors of young Black males. Recruitment occurred in clinics diagnosing and treating sexually transmitted infections. Young Black males living with a parent or guardian (N = 324) were administered a 9-item scale assessing level of perceived parental monitoring. The obtained range was 10–45, with higher scores representing more frequent monitoring. The mean was 29.3 (sd = 7.0). Eight of the twelve outcomes had significant associations with perceived parental monitoring (all in a direction indicating a protective effect). Of these eight, five retained significance in age-adjusted models were ever causing a pregnancy, discussing pregnancy prevention, safer sex, and condom use with sex partners, and using a condom during the last act of penile–vaginal sex. Monitoring by a parent figure may be partly protective against conceiving a pregnancy for Black males 15–23 years of age. PMID:26636026

The aim of this study was to determine the structure of morphological and motor characteristics of Croatian first league female football players and their impact on the estimated quality of the players. According to the goal of the research, a sample consisted of 70 Croatian first league female football players. Participants were measured in 18 tests for assessing morphological characteristics, a set of 12 basic motor abilities tests and a set of 7 tests for assessing football-specific motor abilities. Exploratory factor analysis strategy was applied separately to all measured tests: morphological, basic motor abilities and football specific motor abilities. Factor analysis of morphological tests has shown existence of 3 significant latent dimensions that explain 64% of the total variability. Factors are defined as transverse dimensionality of the skeleton and voluminosity (35%), subcutaneous fat tissue (16%) and longitudinal dimensionality of the skeleton (13%). In the area of basic motor abilities, four factors were extracted. The first factor is responsible for the integration of agility and explosive power of legs, i.e. a factor of movement regulation (agility/lower body explosiveness) (23%), the second one defines muscle tone regulation (15%), the third one defines the frequency of leg movements (12%), while the fourth one is recognized as responsible for the manifestation of basic strength, particularly of basic core strength (19%). Two factors were isolated in the space of football-specific motor abilities: football-specific efficiency (53%) and situational football coordination (27%). Furthermore, by use of factor analysis on extracted latent dimensions (morphological, basic and football specific motor abilities) two higher order factors (explaining 87% of common variability) were extracted. They were named morphological-motor factor (54%) and football-specific motor abilities factor (33%). It is assumed that two extracted higher-order factors fully

Background Despite cultural and religious prohibitions against premarital heterosexual relationships and intimacy, some recent evidence suggests some rise in premarital heterosexual interactions and relationships among young people. On the other hand, although HIV in Iran is a concentrated epidemic and mainly reported among high risk groups such as injecting drug users (IDUs), but there are evidences that the mode of transmission is shifting towards sexual contacts. This trend has caused concern among health policy makers in terms of prevention of STDs and HIV/AIDS particularly, among young people. This paper was prepared with the aim of highlighting how gender contributes to variation in reproductive health needs and conduct of young people in Iran. Method This paper is based on a secondary analysis and compares comparable reproductive beliefs and conducts of women and men based on the data of two surveys conducted in Tehran in 2002 and 2005. A survey among 1385 adolescent males and another survey among 1743 female undergraduate students in four multidisciplinary universities in Tehran. Both surveys used anonymous self-administered questionnaires. To make the two samples comparable, the data of unmarried female university undergraduate students who resided in Tehran were merged with the data of adolescent male students who intended to pursue higher education. Common variables of the two surveys were identified, homogenized, merged and analysed. Results Reproductive health knowledge among male adolescents was poor compared to that of their female peers. Although premarital friendships were moderately acceptable from view points of both males and females, the majority were against premarital sex, particularly among female participants. There were evidences of gender-based double standards in perceptions of premarital sexuality among both males and females; particularly, it was stronger among males than females. Male adolescents reported earlier and greater

Hepatitis B virus (HBV), the leading cause of human hepatocellular carcinoma, is especially virulent in males infected at an early age. Likewise, the murine liver carcinogen Helicobacter hepaticus is most pathogenic in male mice infected before puberty. We used this model to investigate the influence of male sex hormone signaling on infectious hepatitis. Male A/JCr mice were infected with H. hepaticus or vehicle at 4 weeks and randomized into surgical and pharmacologic treatment groups. Interruption of androgen pathways was confirmed by hormone measurements, histopathology, and liver gene and Cyp4a protein expression. Castrated males and those receiving the competitive androgen receptor antagonist flutamide had significantly less severe hepatitis as determined by histologic activity index than intact controls at 4 months. Importantly, the powerful androgen receptor agonist dihydrotestosterone did not promote hepatitis. No effect on hepatitis was evident in males treated with the 5alpha-reductase inhibitor dutasteride, the peroxisome proliferator-activated receptor-alpha agonist bezafibrate, or the nonsteroidal anti-inflammatory drug flufenamic acid. Consistent with previous observations of hepatitis-associated liver-gender disruption, transcriptional alterations involved both feminine (cytochrome P450 4a14) and masculine (cytochrome P450 4a12 and trefoil factor 3) genes, as well gender-neutral (H19 fetal liver mRNA, lipocalin 2, and ubiquitin D) genes. Hepatitis was associated with increased unsaturated C(18) long-chain fatty acids (oleic acid and linoleic acid) relative to saturated stearic acid. Our results indicate that certain forms of androgen interruption can inhibit H. hepaticus-induced hepatitis in young male mice, whereas androgen receptor agonism does not worsen disease. This raises the possibility of targeted hormonal therapy in young male patients with childhood-acquired HBV.

Historical Patterns and Variation in Treatment of Injuries in NFL (National Football League) Players and NCAA (National Collegiate Athletic Association) Division I Football Players.

We conducted a study to identify and contrast patterns in the treatment of common injuries that occur in National Football League (NFL) players and National Collegiate Athletic Association (NCAA) Division I football players. Orthopedic team physicians for all 32 NFL and 119 NCAA Division I football teams were asked to complete a survey regarding demographics and preferred treatment of a variety of injuries encountered in football players. Responses were received from 31 (97%) of the 32 NFL and 111 (93%) of the 119 NCAA team physicians. Although patellar tendon autograft was the preferred graft choice for both groups of team physicians, the percentage of NCAA physicians who allowed return to football 6 months or less after anterior cruciate ligament reconstruction was significantly (P = .03) higher than that of NFL physicians. Prophylactic knee bracing, which may prevent medial collateral ligament injuries, was used at a significantly (P < .0001) higher rate by NCAA teams (89%) than by NFL teams (28%). Ketorolac injections were given by a significantly (P < .01) higher percentage of NFL teams (93%) than of NCAA teams (62%). Understanding the current trends in the management of these injuries is beneficial in designing studies that may help improve the treatment and prevention of injuries in football players.

Whether to use young male or young female reference data to calculate bone mineral density (BMD) T-scores in men remains controversial. The third National Health and Nutrition Examination and Survey (NHANES III) data show that the mean and standard deviation of femoral neck and total hip BMD is greater in young men than young women, and therefore differences in T-scores at these sites using NHANES III female vs male norms becomes less as BMD decreases. In contrast, manufacturer-specific reference databases generally assume similar standard deviations of BMD in men and women. Using NHANES III reference data for the femoral neck and total hip, respectively we found that men with T-scores of -2.5 when young male norms are used have T-scores of -2.4 and -2.3 when young female norms are used. Using manufacturer-specific reference data, we found that men with T-scores of -2.5 when young male norms are used at the femoral neck, total hip, lumbar spine, or one-third of the forearm would have T-scores ranging from -2.4 to -0.4 when young female norms are used, depending on skeletal site and densitometer manufacturer. The change of proportions of men diagnosed with osteoporosis when young female norms are used instead of young male reference data differs substantially according to skeletal site and densitometer manufacturer.

2006-01-01

Among a small, cross-sectional sample of young Black males transitioning from foster care (n = 74), this study explored the relationship of their negative social contextual experiences to two factors relevant to the delivery of mental health services to them: cultural mistrust of mental health professionals and attitudes toward seeking professional help. Three domains of young Black male’s negative social contextual experiences were measured: proximal negative experiences, distal negative experiences, and negative imagery experiences. Results of multivariate an alysis of covariance (MANCOVA) controlling for custody status, counselling status and history, and psychiatric history showed that young Black males reporting a high frequency of negative social contextual experiences reported significantly greater cultural mistrust of mental health professionals and significantly less positive attitudes toward seeking professional help for mental health problems than young Black males reporting a low frequency of negative social contextual experiences. Implications and future research directions are discussed. PMID:16364428

J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to determine if elite football players are becoming bigger, faster, and stronger over the past decade by analyzing individual performances at the National Football League's (NFL) Combine. This study was conducted with (N = 1,263) subjects from the 1999-2000 (99-00) NFL Combines (n = 635) and the 2015-2016 (15-16) NFL Combines (n = 628) separated by position. Data were collected for height, weight, 40-yd (36.58 m) dash, NFL 225 lb. (102.06 kg) repetitions test, vertical jump (VJ), broad jump (BJ), pro-agility shuttle, and 3-cone drill. Statistical significance between the years for all subjects participating in the NFL Combine was found for the 40-yd dash (99-00: mean ± SD = 4.85 ± 3.2; 15-16: 4.80 ± 3.5; p = 0.002) and VJ (99-00 = 32.30 ± 4.08; 15-16: 32.86 ± 4.17; p = 0.028) at the alpha p < 0.05 level. Statistical significance was also found for BJ (99-00 = 111.37 ± 8.81; 15-16: 115.03 ± 9.22; p < 0.001) and the 3-cone drill (99-00 = 7.41 ± 0.42; 15-16: 7.29 ± 4.1; p < 0.001) at the alpha p < 0.001 level. There were no statistically significant findings (p > 0.05) for weight or height found across all subjects by combine years. Results indicate that elite football players have improved their performance, when comparing results from 1999-2000 to 2015-2016. These finding may be beneficial to NFL franchises in their prospective player assessments.

The aim of the study was to examine the development of specific physical, physiological, and biomechanical parameters in 29 young male swimmers for whom measurements were made three times for two consecutive years. During the 400-m front-crawl swimming, the energy cost of swimming, and stroking parameters were assessed. Peak oxygen consumption (VO2 peak) was assessed by means of the backward-extrapolation technique recording VO2 during the first 20 sec. of recovery period after a maximal trial of 400-m distance. Swimming performance at different points of physical maturity was mainly related to the increases in body height and arm-span values from physical parameters, improvement in sport-specific VO2 peak value from physiological characteristics, and improvement in stroke indices on biomechanical parameters. In addition, biomechanical factors characterised best the 400-m swimming performance followed by physical and physiological factors during the 2-yr. study period for the young male swimmers.

Our purpose was to determine concussion mechanism and activity differences among three cohorts of football players: youth, high school, and college. Participants in this prospective cohort study were youth (ages 5-14 years, 118 teams, 310 team-seasons), high school (96 teams, 184 team-seasons), and college (34 teams, 71 team-seasons) football players. Athletic trainers collected athlete-exposure (AE) and concussion data during the 2012-2014 seasons. Injury mechanism referred to the object that made contact with the concussed player, resulting in the concussion. Injury activity referred to the type of football-specific activity that the player was involved in when the concussion was sustained. Injury proportion ratios (IPR) compared distributions of concussion mechanisms and activities among age levels. A total of 1429 concussions were reported over 1,981,284 AE across all levels (Rate: 0.72/1000AE). Overall, most concussions were caused by player contact (84.7%). During games, a greater proportion of youth football concussions (14.7%) were caused by surface contact than high school (7.3%, IPR = 2.02; 95% confidence interval [CI]: 1.10-3.72) and college (7.1%, IPR = 2.07, 95% CI: 1.02-4.23) football. Compared with college football concussions (90.2%), a smaller proportion of youth (80.0%, IPR = 0.89, 95% CI: 0.79-0.99) and high school (83.2%, IPR = 0.92, 95% CI: 0.86-0.99) football concussions were caused by player contact. A greater proportion of game youth football concussions (42.1%) occurred while an individual was being tackled than occurred in high school (23.2%, IPR = 1.81, 95% CI: 1.34-2.45) and college (23.0%, IPR = 1.83, 95% CI: 1.29-2.62) football. Findings were similar during practices. Compared with college football game concussions (15.8%), a smaller proportion of youth (6.3%, IPR = 0.40, 95% CI: 0.17-0.93) and high school (9.5%, IPR = 0.60, 95% CI: 0.38-0.95) football game concussions occurred while an individual was

The aim of this study was to identify risk factors related to the occurrence of injuries in football players. The study included 216 football players from 12 teams in the elite football league. Football-related injury data were collected prospectively during the 2012/2013 competitive season. At baseline the following information was collected for the players: anthropometric measurements (weight, height, BMI, subcutaneous skinfolds), playing experience, injury history, physical fitness performance test (agility run), peak oxygen uptake. The incidence, type and severity of injuries and training and game exposure times were prospectively documented for each player. Most of the players (n = 155, 71.7%) sustained the injures during the study period. The overall injury incidence during the regular season was 6.3 injuries per 1000 athlete-exposures (95% confidence interval, 4.31-9.67). Multivariate logistic regression analysis showed that playing experience (odds ratio [OR] = 0.44; 95% CI = 0.32-0.61, p < 0.01), age (OR = 2.05; 95% CI = 1.49-2.81, p < 0.01) and a previous injury (OR = 4.4; 95% CI = 2.14-9.07, p < 0.01) were significantly correlated to increased risk of injuries. Body mass index was not associated with risk of injury. Strains (34.19%) and sprains (25.81%) were the major injury types. Twenty-seven percent of injured players were absent from football for more than 1 month, with knee injuries (25.42%) being the most severe type. The risk factors that increase injury rates in football players were previous injury, higher age and years of playing. Future research should include adequate rehabilitation program to reduce the risk of injuries.

Detection of nandrolone metabolites in urine after a football game in professional and amateur players: a Bayesian comparison.

Nandrolone (19-nortestosterone) is a widely used anabolic steroid in sports where strength plays an essential role. Once nandrolone has been metabolised, two major metabolites are excreted in urine, 19-norandrosterone (NA) and 19-noretiocholanolone (NE). In 1997, in France, quite a few sportsmen had concentrations of 19-norandrosterone very close to the IOC cut off limit (2ng/ml). At that time, a debate took place about the capability of the human male body to produce by itself these metabolites without any intake of nandrolone or related compounds. The International Football Federation (FIFA) was very concerned with this problematic, especially because the World Cup was about to start in France. In this respect, a statistical study was held with all football players from the first and second divisions of the Swiss Football National League. All players gave a urine sample after effort and around 6% of them showed traces of 19-norandrosterone. These results were compared with amateur football players (control group) and around 6% of them had very small amounts of 19-norandrosterone and/or 19-noretiocholanolone in urine after effort, whereas none of them had detectable traces of one or the other metabolite before effort. The origin of these compounds in urine after a strenuous physical activity is still unknown, but three hypotheses can be put forward. First, an endogenous production of nandrolone metabolites takes place. Second, nandrolone metabolites are released from the fatty tissues after an intake of nandrolone, some related compounds or some contaminated nutritive supplements. Finally, the sportsmen may have taken something during or just before the football game.

Science and football: evaluating the influence of science on performance.

Drust, B; Green, M

2013-01-01

The scientific study of football has its origins in the early research completed in the 1970's. Since these early efforts the available scientific knowledge base related to football has developed substantially. The ability of this scientific information to influence practice in the day-to-day activity of football organisations, especially elite teams, has been largely taken for granted. The close examination of this impact can lead to more uncertainty regarding the usefulness of the scientific data to the sport. Few articles are available that have attempted to critique the link between science and football practice. As such, the aims of this article are 2-fold; (i) to examine the historical background to "science and football" and to analyse the influence of sports science research on the current practice of coaches and practitioners within the sport and (ii) to identify potential ways to increase the influence of scientific research on practice in the "real world".

We identified the perceptual-cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n = 127) completed an adapted participation history questionnaire and video-based assessments of perceptual-cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual-cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual-cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification.

This study examined the masturbatory experiences and other sexual activities of young Korean males in military service. The actual status of masturbation and its relationship to sexual activity questionnaire. A total of 1,212 young males among military personnel in Korea were interviewed with sexuality questionnaires on masturbation, sexual intercourse and personal characteristics. We divided these subjects into four groups according to the age of initiation of masturbation and analyzed the relationship between masturbation and other sexual activities. The mean age of subjects was 22.03 +/- 1.22 (19-27) years. The percentage of men who reported ever having masturbated was 98.1% (1189/1212) and the average age of initiation of masturbation was 14.26 +/- 1.66 years. So we divided 1,212 males into four groups on the basis of the average age below and above one standard deviation. Overall, 67.7% (821/1212) had experienced sexual intercourse, and significantly, the earlier the initiation age of masturbation, the higher the coitus rate in each group (p < 0.05). About 21.5% of the men who were not virgins had experienced their first sexual intercourse with prostitutes. The mean age of first coitus, the incidence of sexually transmitted disease (STD) and the frequency of masturbation were closely linked to the initiation age of masturbation, respectively (p < 0.05). A masturbatory guilt feeling was seen in about 10.9% (132/1212) and there was no significant difference according to the types of religious worship (p = 0.227). On the basis of this study, sexual activities generally increased accordingly as the beginning of masturbation was earlier. Coital incidence in this study was 67.7% for young males in Korean military service, and 21.5% of them had their first sexual intercourse with prostitutes. Prostitution still plays an important role in the sexual lives of males in Korea. The incidence of STD was over 10% and homosexual manifestation was seen in 1.07% of subjects

The purpose of this study was to assess the characteristics and prevalence of sports-related injuries in visually disabled athletes of the Brazilian football 5-a-side team. The participants were 13 male athletes, all classified as B1 visual class, members of the Brazilian team, who played in five consecutive international competitions. Data were collected using the Brazilian Paralympic Committee and the Brazilian Confederation of Sports for the Blind report form. From the total of 13 athletes, 11 succumbed to some form of injury during the 5 competitions, which incorporated 23 matches, representing a prevalence of 84.6%. A total of 35 sports injuries were recorded, giving a clinical incidence of 2.7 injuries per athlete and an injury risk of 0.85 and an incidence rate of 0.12 injuries per match. Traumatic injuries (80%) were more common than overuse injuries (20%) (p<0.05). The highest distribution of injury was in the lower limbs (80%), followed by the head (8.6%), spine (5.7%) and upper limbs (5.7%). The body regions most affected were the knee (28.6%), feet (17.1%), ankle (11.4%) and thigh (11.4%). Contusions (31.4%), sprains (25.7%) and tendinopathy (8.6%) were the most frequent diagnoses. This is the first study to describe the nature and prevalence of sports-related injuries in 5-a-side football in blind athletes. The results are important in guiding strategies to inform the implementation of preventive pathways and provide a strong rationale for the compulsory use of additional protective equipment. © Georg Thieme Verlag KG Stuttgart · New York.

Ascending aortic dimensions are slightly larger in young competitive athletes compared with sedentary controls, but rarely >40 mm. Whether this finding translates to aortic enlargement in older, former athletes is unknown. This cross-sectional study involved a sample of 206 former National Football League (NFL) athletes compared with 759 male subjects from the DHS-2 (Dallas Heart Study-2; mean age of 57.1 and 53.6 years, respectively, P <0.0001; body surface area of 2.4 and 2.1 m 2 , respectively, P <0.0001). Midascending aortic dimensions were obtained from computed tomographic scans performed as part of a NFL screening protocol or as part of the DHS. Compared with a population-based control group, former NFL athletes had significantly larger ascending aortic diameters (38±5 versus 34±4 mm; P <0.0001). A significantly higher proportion of former NFL athletes had an aorta of >40 mm (29.6% versus 8.6%; P <0.0001). After adjusting for age, race, body surface area, systolic blood pressure, history of hypertension, current smoking, diabetes mellitus, and lipid profile, the former NFL athletes still had significantly larger ascending aortas ( P <0.0001). Former NFL athletes were twice as likely to have an aorta >40 mm after adjusting for the same parameters. Ascending aortic dimensions were significantly larger in a sample of former NFL athletes after adjusting for their size, age, race, and cardiac risk factors. Whether this translates to an increased risk is unknown and requires further evaluation. © 2017 American Heart Association, Inc.

We present the results of the autopsy of a retired professional football player that revealed neuropathological changes consistent with long-term repetitive concussive brain injury. This case draws attention to the need for further studies in the cohort of retired National Football League players to elucidate the neuropathological sequelae of repeated mild traumatic brain injury in professional football. The patient's premortem medical history included symptoms of cognitive impairment, a mood disorder, and parkinsonian symptoms. There was no family history of Alzheimer's disease or any other head trauma outside football. A complete autopsy with a comprehensive neuropathological examination was performed on the retired National Football League player approximately 12 years after retirement. He died suddenly as a result of coronary atherosclerotic disease. Studies included determination of apolipoprotein E genotype. Autopsy confirmed the presence of coronary atherosclerotic disease with dilated cardiomyopathy. The brain demonstrated no cortical atrophy, cortical contusion, hemorrhage, or infarcts. The substantia nigra revealed mild pallor with mild dropout of pigmented neurons. There was mild neuronal dropout in the frontal, parietal, and temporal neocortex. Chronic traumatic encephalopathy was evident with many diffuse amyloid plaques as well as sparse neurofibrillary tangles and tau-positive neuritic threads in neocortical areas. There were no neurofibrillary tangles or neuropil threads in the hippocampus or entorhinal cortex. Lewy bodies were absent. The apolipoprotein E genotype was E3/E3. This case highlights potential long-term neurodegenerative outcomes in retired professional National Football League players subjected to repeated mild traumatic brain injury. The prevalence and pathoetiological mechanisms of these possible adverse long-term outcomes and their relation to duration of years of playing football have not been sufficiently studied.

Sudden cardiac arrest (SCA) remains a tragic occurrence on the football field. The limits of preparticipation cardiovascular screening make it compulsory that prearranged emergency medical services be available at all football matches to immediately respond to any collapsed player. Management of SCA involves prompt recognition, immediate cardiopulmonary resuscitation (CPR) and early defibrillation. Any football player who collapses without contact with another player or obstacle should be regarded as being in SCA until proven otherwise. An automated external defibrillator (AED), or manual defibrillator if an AED is not available, should be immediately accessible on the field during competitions. This study presents guidelines for a practical and systematic approach to the management of SCA on the football field.

The total skeletal bone mineral content (BMC), bone mineral density (BMD), bone size, and body composition were measured by dual-energy x-ray absorptiometry (DXA) in all professional male football players of a 1st division team (n = 24) and age- and BMI-matched (n = 22) controls (less than 3 hours of recreational sport activities per week). Average (+/- 1 SD) age of the athletes was 22.6 +/- 2.5 years. Intensive training is conducted during 48 weeks a year for 20-22 hours/week. The length of the registered playing career before the study was 8.2 +/- 2.7 years. Total skeleton BMC was 18.0% (P < 0.001) greater in the football players. The difference resulted from the sum of 5.2% (P < 0.02) increment of bone size and 12.3% (P < 0.001) increment of BMD. The analysis of skeletal subareas revealed that the difference of the BMC and BMD was greater at the level of the pelvis and legs compared with the arms or trunk. The BMC and BMD of the head was equal for both groups. Also, the bone size of the legs and pelvis was significantly greater for the players compared with controls; there was no difference at the level of the arms or head. Within the group of football players the increment of total skeleton BMD was similar in the young players, with less than 7 years of practice (age 20.6 +/- 0.9 years) compared with relative older players (age 24.6 +/- 1.9) with more than 7 years of practice. Lean body mass was significantly greater in the players (63.3 +/- 4.0 kg) compared with the controls (56.7 +/- 3.6, P < 0.001) whereas fat mass was markedly lower (9.4 +/- 2.9 kg versus 14.9 +/- 6.3 kg), P < 0.002). The BMD of the controls was significantly correlated to total weight, height, and lean mass whereas the BMD of the players was only correlated to muscle mass. The calcium intake from dairy products was similar in both groups. The range of calcium intake was wide among the players (184-2519 mg/day) but it was not significantly correlated to BMD (r = 0.03).

Behavioral and emotional factors are triggers of cardiovascular events (CVE). It remains uncertain whether football fans, particularly individuals with coronary artery disease (CAD), are at increased risk for CVE. To assess the effect of watching football matches in patients with known CAD on the incidence of ECV according to the match result. We prospectively evaluated 82 male football supporters, in 23 matches, with history of acute coronary syndrome during matches of the 2015/2016 season. Each individual was evaluated once and monitored with Holter on the day of their team's match and on the control day. Evaluated as the primary endpoint the composite of death, stroke, re-infarct angor or sustained arrhythmias. It was also evaluated as secondary endpoints, episodes of non-sustained supraventricular or ventricular dysrhythmia and mean heart rate (HR). The mean age was 61 ± 10 years. Compared with the control day, despite the significant increase of the HR (p <0.001), that was independent of the result (p> 0.97), the number of cardiovascular events was not different considering the result (p> 0.05). Moreover, the number of non-sustained episodes of supraventricular and ventricular dysrhythmia were not different stratifying according to the match result (p> 0.05). The match result was not associated with a different incidence of cardiovascular events in patients with past history of CAD, with ischemic and arrhythmic substrate, who watched football matches on television.

2014-01-01

Awareness of myocarditis in association with inflammatory bowel diseases is crucial as it bears a rare but serious risk for mortality. This report describes the case of a young Caucasian male, whose heart biopsy was tested negative for giant cells and bacterial or viral genomes or proteins. He was experiencing severe lymphocytic myocarditis (other than mesalamine-induced) along with cardiogenic shock during ulcerative colitis exacerbation. This is an extremely rare, if not unique, clinical constellation. We chose to study the epidemiologic grounds and all major aspects of differential pathogenesis and treatment of this serious health problem. PMID:24576324

This study was conducted to assess whether choices of physical activity, smoking status, and parental education and income were correlated with the health status of young adult males which are important for preventive health policy. 491 18-29-year old males from lower socioeconomical districts in Turkey participated in this study. Information about demographic characteristics, parental education, household income, smoking status, and physical activity was obtained by means of a standardized questionnaire. BMI and metabolic parameters (serum lipid profile) were assessed. Mean total cholesterol, LDL, HDL and triglyceride levels were in the normal range. The physically active group displayed a better lipid profile. No relationship was found between parental education and serum lipids. Smoking was slightly correlated with household income (r=103, p=0.022). Young adult males who participate in relatively high levels of physical activity are at lower CHD risk than less active ones. The present study also showed that lower socioecnomic status does not always correlate with higher levels of cardiovascular risk factors. In conclusion, data supports that while family history cannot be changed, HDL levels can be modulated by lifestyle factors as in other populations and that with the determined benefits of increasing physical activity and thus, HDL levels, policy reform in schools to promote physical activity are warranted.

Evidence of the relative age effect in football in Australia.

2012-01-01

The birth date distributions of elite male and female footballers in Australia, from junior youth (age 14 and upwards) to senior (professional) players, were examined. A statistically significant relative age effect was found among junior male players, reducing in effect with increasing age. An inter-year relative age effect that became apparent among the players at national level in the Under-17 and Under-20 age groups, due to the timing of the respective World Cups for those age groups, was also identified. It is conjectured that this might lead to players born in certain years having a curtailed pathway in the elite game, leading to drop-out among this very elite group. In the case of women elite players, no significant relative age effect was found among youth players, possibly due to less fierce competition for places, although a significant effect was found to exist at senior elite level.

Cam deformity (CD) is likely a bony adaptation in response to high-impact sports practice during skeletal growth. We ascertained whether a dose-response relationship exists between the frequency of football practice during skeletal growth and the presence of a CD in adulthood, and if the age at which a football player starts playing football is associated with the presence of a CD in adulthood. Prevalence of a CD (α angle>60°) and a pathological CD (α angle>78°) was studied using standardised anteroposterior (AP) and frog-leg lateral (FLL) radiographs that were obtained during seasonal screening. The age of starting to play football with a low frequency (LF; ≤3 times/week) and high frequency (HF; ≥4 times/week) was retrospectively assessed. The differences in prevalence of a CD per hip, in either view, between groups were calculated by logistic regression with generalised estimating equations. 63 players (mean(±SD) age 23.1(±4.2) years) participated, yielding 126 hips for analysis. The prevalence of a CD in the FLL was 40% (n=82) in players who started playing HF football from the age of 12 years or above, and 64% (n=44) in those playing HF football before the age of 12 years (p=0.042). This was also true for a pathological CD (12% vs 30%, p=0.038). The AP views revealed no difference. Our results indicate a probable dose-response relationship between the frequency of football practice during skeletal growth and the development of a CD, which should be confirmed in future prospective studies.

The relationship between atopic dermatitis (AD) and psychological distress has been well established for children and adolescents. However, it is unclear whether this relationship exists in young adults. This study aimed to assess the relationship between AD and psychological distress in young male adults in South Korea. A cross-sectional study was conducted using regional conscription data from 2008 to 2012. A dermatologist diagnosed AD based on historical and clinical features, and determined severity using the eczema area and severity index. A psychiatrist used medical records, an interview, and a psychological test to examine psychological distress (depression, anxiety, and somatization). The relationship between psychological distress and AD was assessed by multivariate logistic regression analyses. Among the 120,508 conscripts, 1517 (1.2%) presented with AD. The odds of having each type of psychological distress were significantly greater for individuals with AD compared with those without AD. The adjusted odds ratios for depression, anxiety, and somatization were 1.79 (95% CI 1.40-2.29), 1.38 (95% CI 1.08-1.76), and 1.75 (95% CI 1.40-2.20), respectively. Moderate-to-severe AD was significantly related to depression and somatization to a greater extent compared with mild AD. Depression, anxiety, and somatization are strongly and independently associated with AD in young adult males. Early treatment of skin inflammation might modify the risk of psychiatric problems. Prospective cohort studies are needed to verify causal relationships.

ABSTRACT The Red-cockaded Woodpecker (Picoides borealis) is an endangered species endemic to pine (Pinus spp.) forests of the southeastern United States. I examined Red-cockaded Woodpecker foraging behavior to learn if there were male/female differences at the Savannah River Site, South Carolina. The study was conducted in largely young forest stands (,50 years of age) in contrast to earlier foraging behavior studies that focused on more mature forest. The Redcockaded Woodpecker at the Savannah River site is intensively managed including monitoring, translocation, and installation of artificial cavity inserts for roosting and nesting. Over a 3-year period, 6,407 foraging observations covering sevenmore » woodpecker family groups were recorded during all seasons of the year and all times of day. The most striking differences occurred in foraging method (males usually scaled [45% of observations] and females mostly probed [47%]),substrate used (females had a stronger preference [93%] for the trunk than males [79%]), and foraging height from the ground (mean 6 SE foraging height was higher for males [11.1 6 0.5 m] than females [9.8 6 0.5 m]). Niche overlap between males and females was lowest for substrate (85.6%) and foraging height (87.8%), and highest for tree species (99.0%), tree condition (98.3%), and tree height (96.4%). Both males and females preferred to forage in older, large pine trees. The habitat available at the Savannah River Site was considerably younger than at most other locations, but the pattern of male/female habitat partitioning observed was similar to that documented elsewhere within the range attesting to the species’ ability to adjust behaviorally.« less

While yoga is thought to reduce the risk of chronic non-communicable diseases such as diabetes, there are no studies on insulin sensitivity in long term practitioners of yoga. We assessed insulin sensitivity and cardiac autonomic function in long term practitioners of yoga. Fifteen healthy, young, male practitioners of yoga were compared with 15 young, healthy males who did not practice yoga matched for body-mass index. Fasting insulin sensitivity was measured in the fasting state by the hyperinsulinaemic-euglycaemic clamp. There were no significant differences between the groups in their anthropometry or body composition. However, the fasting plasma insulin was significantly lower in the yoga group. The yoga group was also more insulin sensitive (yoga 7.82 [2.29] v. control 4.86 [11.97] (mg/[kg.min])/(microU/ml), p < 0.001). While the body weight and waist circumference were negatively correlated with glucose disposal rate in the controls, there were no similar correlations in the yoga group. The yoga group had significantly higher low-frequency power and lower normalized high-frequency power. Long term yoga practice (for 1 year or more) is associated with increased insulin sensitivity and attenuates the negative relationship between body weight or waist circumference and insulin sensitivity.

We sought to determine the association of four categories (chunks) of variables: (1) demographic characteristics, (2) family and friends smoking and other drug use, (3) psychosocial factors and attitude, and (4) lifestyle factors to current smoking as compared to never smoking among Canadian young adults. A cohort of 1270 young adults, followed for 10 years, completed a self-administered questionnaire. In multivariable analyses, the best final model for both genders did not include the psychosocial and attitudinal categories, but did contain variables in the demographic, family and friends, and lifestyle categories. Interventions for reducing smoking among young adults may be similar for males and females, a conclusion that differs from conclusions based on findings from younger age groups.

Background Neurodynamics intervention is known to increase apparent muscle extensibility, but information regarding hamstring responses after a neurodynamic sliders (NS) technique is scarce. The aim of this study was to evaluate the effects of NS on apparent hamstring extensibility and activity in footballers with hamstring tightness. Methods Forty eligible healthy male footballers with hamstring tightness were each randomly allocated to either a 4-week NS technique or a control group (CG) receiving placebo shortwave intervention. Knee extension angles were measured with the passive knee extension test, and maximal voluntary isometric contraction (MVIC) of hamstrings was measured by a surface electromyography at baseline and after intervention sessions. Results The results showed that NS produced a statistically and clinically significant increase in knee extension angle compared to CG (P < 0.001); however, there was no difference between the groups receiving MVIC of hamstrings. Within group comparison, NS also provided a significant increase in knee extension angle (P < 0.001), whereas the control group did not. There was no change in hamstring MVIC in either group after intervention. Conclusions The findings of this study reveal that four weeks of NS technique improved apparent hamstring extensibility but did not change the hamstring activity in footballers with hamstring tightness.

To examine the association between pre-season training variables and subsequent in-season performance in an elite Australian football team. Data from forty-one elite male Australian footballers (mean±SD: age=23.4±3.1y; height=188.4±7.1cm; mass=86.7±7.9kg) was collected from one Australian Football League (AFL) club. Pre-season training data (external load, internal load, fitness testing and session participation) were collected across the 17-week pre-season phase (6-weeks pre-Christmas, 11-weeks post-Christmas). Champion Data© Player Rank (CDPR), coaches' ratings (CR) and round one selection were used as in-season performance measures. CDPR and CR were examined over the entire season, first half of the season and the first four games. Both Pearson and partial (controlling for AFL age) correlations were calculated to assess if any associations existed between pre-season training variables and in-season performance measures. A median-split was also employed to differentiate between higher and lower performing players for each performance measure. Pre-season training activities appeared to have almost no association with performance measured across the entire season and the first half of the season. However, many pre-season training variables were significantly linked with performance measured across the first four games. Pre-season training variables that were measured post-Christmas were the most strongly associated with in-season performance measures. Specifically, Total on-field session rating of perceived exertion (sRPE) post-Xmas, a measurement of internal load, displayed the greatest association with performance. Late pre-season training (especially on-field match specific training) is associated with better performance in the early season.

Individuals with an impairment comprise more than 15% of the world's population, many of whom can benefit greatly from participation in sport. The provision of medical services in disability sport is a challenging area with a lack of scientific evidence. Given the positive impact that sport can have on the people with an impairment, it is vital that measures are taken to better understand the medical issues posed by disability sport. It is well established that medications and supplements are overused in sport, particularly within professional football, but there is no current evidence on medication or supplement use in elite disability football. To examine and describe the use of medication and supplements in disability football, before and during international tournaments, and to identify the profile of substances used by category. Prospective, descriptive, cohort study. International Blind Sport Association Football World Cup 2015 and the International Federation of Cerebral Palsy Football World Cup 2015. Two hundred forty-two elite-level disability footballers, classified with B1 visual impairment or cerebral palsy. Team clinicians were asked to document all medication and supplements taken in the 48 hours before each match. This study recorded the use of 1648 substances in 242 players, with more than one half (53.1%) classified as supplements. There was an overall rate of 1.26 substances used per player per match and a medication use rate of 0.59 medications per player per match. Seventy percent (170/242) of players reported using at least one substance per tournament, with 57.9% (140/242) using at least one prescribed medication (63.6% of players at International Blind Sports Association World Games and 57.7% of players at International Federation of Cerebral Palsy World Cup). The most commonly prescribed category of medications was nonsteroidal anti-inflammatory drugs, representing 39.3% of all reported medications. This study highlights the potential

Objective—To describe the long term impact of football on the health related quality of life (HRQL) of former professional footballers in the United Kingdom. Method—A cross sectional survey gathered data from 284 former professional players. Respondents reported medical treatments, osteoarthritis (OA) diagnosis, other morbidity, disability status, and work related disability since their football career. The EuroQol (EQ-5D) and global health rating scales were selected to assess HRQL. Results—Medical treatment for football related injuries was a common feature, as was OA, with the knee being the most commonly affected joint. Respondents with OA reported poorer HRQL compared with those without OA. As with medical treatments and problems on each of the five EQ-5D dimensions (pain, mobility, usual activities, anxiety/depression, self care), frequency of disability and work related disability were higher among respondents with OA than those without. Conclusion—This exploratory study suggests that playing professional football can impact on the health of United Kingdom footballers in later life. The development of OA was associated with poorer outcomes on all aspects of HRQL. Key Words: football; retirement; osteoarthritis; knee; health related quality of life PMID:11049141

There is no other sport that has come under greater scrutiny surrounding the incidence and treatment of concussion than football, and there is no other professional sports league that has experienced more intense focus of its handling of concussions than the National Football League (NFL). The NFL has received significant criticism of their management of concussion in players from both the popular press and the medical community. However, those working with active NFL players have changed their assessment and treatment of these injuries as the knowledge of concussions has evolved over time. We review the current approach to the management of concussions in the professional football player. © 2014 S. Karger AG, Basel.

Priorities for injury prevention in women's Australian football: a compilation of national data from different sources.

Fortington, Lauren V; Finch, Caroline F

2016-01-01

Participation in Australian football (AF) has traditionally been male dominated and current understanding of injury and priorities for prevention are based solely on reports of injuries in male players. There is evidence in other sports that indicates that injury types differ between males and females. With increasing participation in AF by females, it is important to consider their specific injury and prevention needs. This study aimed to provide a first injury profile from existing sources for female AF. Compilation of injury data from four prospectively recorded data sets relating to female AF: (1) hospital admissions in Victoria, 2008/09-13/14, n=500 injuries; (2) emergency department (ED) presentations in Victoria, 2008/09-2012/13, n=1,879 injuries; (3) insurance claims across Australia 2004-2013, n=522 injuries; (4) West Australian Women's Football League (WAWFL), 2014 season club data, n=49 injuries. Descriptive results are presented as injury frequencies, injury types and injury to body parts. Hospital admissions and ED presentations were dominated by upper limb injuries, representing 47% and 51% of all injuries, respectively, primarily to the wrist/hand at 32% and 40%. Most (65%) insurance claim injuries involved the lower limb, 27% of which were for knee ligament damage. A high proportion of concussions (33%) were reported in the club-collected data. The results provide the first compilation of existing data sets of women's AF injuries and highlight the need for a rigorous and systematic injury surveillance system to be instituted.

Male factor infertility plays a significant role in infertility. Many factors have been associated with male infertility; however, the link between many sports and recreational factors and male reproduction remains poorly characterized. To evaluate the current literature regarding the impact of many common sports and recreational factors on male reproduction. A comprehensive PubMed and Embase search for relevant articles published between 1970 and 2017 was performed by combining the following search terms: male, sports (including individual sports), traumatic brain injury, sauna, hot tub, fertility, erectile dysfunction, varicocele, environment, cell phone, and laptop computer. Hypogonadism and erectile dysfunction can be associated with sports with high rates of head injuries, such as American football. Although early reports linked other sports, such as bicycling, to erectile dysfunction, subsequent studies isolated these associations to sports cycling rather than recreational cycling. Certain sports (football, basketball, handball, and volleyball) were linked to increasing prevalence and severity of varicocele, offering a potential link to male infertility. In addition, recreational activities such as sauna, hot tubs, Jacuzzis, heated car seats, and laptop use were associated with high testicular temperature, which can impair spermatogenesis. Radio frequency electromagnetic waves from cell phones and laptops have also been shown to have deleterious effects on sperm viability and motility. Many common sports and daily activities represent potential sources of male infertility. Clinicians should be aware of these associations in explaining idiopathic infertility in males. Male infertility is an often overlooked component of a couple's inability to conceive. We outline many common and often overlooked sports and recreational exposures that have been associated with male infertility. Copyright © 2018 European Association of Urology.

FIFA 11+: an effective programme to prevent football injuries in various player groups worldwide—a narrative review

PubMed Central

Bizzini, Mario; Dvorak, Jiri

2015-01-01

In 2009, FIFA promoted and disseminated the FIFA 11+ injury prevention programme worldwide. Developed and studied by the FIFA Medical Assessment and Research Centre (F-MARC), the programme was based on a randomised controlled study and one countrywide campaign in amateur football that significantly reduced injuries and healthcare costs. Since the FIFA 11+ launch, key publications have confirmed the preventive effects of the programme and have evaluated its performance effects in female as well as male amateur football players. Furthermore, implementation strategies of this prevention programme have also been studied. The goal of this narrative review was to summarise the available scientific evidence about the FIFA 11+ programme. While FIFA continues to disseminate and implement FIFA 11+ among its Member Associations, adaptations of the injury prevention programme for children and referees have been developed and are currently being evaluated.

“You’re Not Born with Talent” Talented Girls’ and Boys’ Perceptions of Their Talents as Football Players

PubMed Central

Sæther, Stig Arve; Mehus, Ingar

2016-01-01

Generally in sports, there is a strong assumption of a connection between skill level in young age and adulthood. Studies have mainly focused on the coaches’ understanding and role in identifying and developing talent. In this article we turn our attention towards the athletes’ perspectives, interviewing talented young football players (five boys and five girls) about their perceptions of their own talent and development. The objective of the article is to investigate how boys and girls perceive their talent and to discuss how various perceptions influence coaching practice in talent development. We introduce the following questions: (a) do the players use a static or dynamic perception of their own talent and (b) do the players consider specific or general skills to be most important in their skill development? Results show that the boys have a more static perception of talent compared to the girls. Furthermore, the boys in this study stress the importance of highly specified skills. The girls have a more balanced view on what is important, but tend to stress the importance of basic skills. The study suggests two potential implications. First, the coaches should be aware of the possible vulnerability following players’ static perception of talent. Second, an exclusive focus on specified skills might make for less optimal preparation for the changing demands young players meet when moving through the different levels of play on their way to high level football. In future research it would be interesting to investigate how players with a lower skill level, not yet regarded as talent, perceive their talent and skill development. PMID:29910254

IMPORTANCE Players of American football may be at increased risk of long-term neurological conditions, particularly chronic traumatic encephalopathy (CTE). OBJECTIVE To determine the neuropathological and clinical features of deceased football players with CTE. DESIGN, SETTING, AND PARTICIPANTS Case series of 202 football players whose brains were donated for research. Neuropathological evaluations and retrospective telephone clinical assessments (including head trauma history) with informants were performed blinded. Online questionnaires ascertained athletic and military history. EXPOSURES Participation in American football at any level of play. MAIN OUTCOMES AND MEASURES Neuropathological diagnoses of neurodegenerative diseases, including CTE, based on defined diagnostic criteria; CTE neuropathological severity (stages I to IV or dichotomized into mild [stages I and II] and severe [stages III and IV]); informant-reported athletic history and, for players who died in 2014 or later, clinical presentation, including behavior, mood, and cognitive symptoms and dementia. RESULTS Among 202 deceased former football players (median age at death, 66 years [interquartile range, 47–76 years]), CTE was neuropathologically diagnosed in 177 players (87%; median age at death, 67 years [interquartile range, 52–77 years]; mean years of football participation, 15.1 [SD, 5.2]), including 0 of 2 pre–high school, 3 of 14 high school (21%), 48 of 53 college (91%), 9 of 14 semiprofessional (64%), 7 of 8 Canadian Football League (88%), and 110 of 111 National Football League (99%) players.

Pectoralis major injuries are an infrequent shoulder injury that can result in pain, weakness, and deformity. These injuries may occur during the course of an athletic competition, including football. The purpose of this study was to determine the incidence of pectoralis major ruptures in professional football players and time lost from the sport following injury. We hypothesized that ruptures most frequently occur during bench-press strength training. The National Football League Injury Surveillance System was reviewed for all pectoralis major injuries in all players from 2000 to 2010. Details regarding injury setting, player demographics, method of treatment, and time lost were recorded. A total of 10 injuries-complete ruptures-were identified during this period. Five of the 10 were sustained in defensive players, generally while tackling. Nine occurred during game situations, and 1 occurred during practice. Specific data pertinent to the practice injury was not available. No rupture occurred during weight lifting. Eight ruptures were treated operatively, and 2 cases did not report the method of definitive treatment. The average days lost was 111 days (range, 42-189). The incidence was 0.004 pectoralis major ruptures during the 11-year study period. Pectoralis major injuries are uncommon while playing football. In the National Football League, these injuries primarily occur not during practice or while bench pressing but rather during games. When pectoralis major ruptures do occur, they are successfully treated operatively. Surgery may allow for return to full sports participation. IV, case series.

Cromwell, F; Walsh, J; Gormley, J

2000-01-01

Objectives—To quantify injuries in elite gaelic footballers and to determine the nature, sites, and outcome of injuries and the possible risk factors involved. Methods—Information on injuries was collected from six elite gaelic football teams by a questionnaire. The footballers were asked to recall injuries over the preceding six month period. Results—A total of 88 out of 107 subjects sustained injuries over the study period. Ninety five injuries were recorded, giving an incidence rate of 1.78 injuries per subject per year, of which 35% were recurring. It was found that 35% of injuries were sustained during training sessions. Lower body injuries predominated (77%), the ankle being the most commonly injured anatomic site. Most injuries were soft tissue in nature: muscle, 33%; ligament, 32%; tendon, 16%. The most common situations giving rise to injuries were collision (22%) and twist/turn (19%). Foul play only accounted for about 6% of injuries. Mean time off play as a result of injury was 17.3 days, and hospital admission was necessary for 15% of the injuries. Conclusion—Despite the limitations of a retrospective of this nature, the study provides useful and important information on injuries in gaelic footballers.

The Irish brawn drain: English League clubs and Irish footballers, 1946-1995.

PubMed

McGovern, P

2000-09-01

This paper draws on world systems and resource dependency theories to show how the changing recruitment practices of English League clubs have deepened the brawn drain from Irish football, thereby compounding its underdevelopment. An analysis of the origins, method of recruitment and destinations of Irish players (North and South) who appeared in the English League between 1946 and 1995 shows that English clubs imported large numbers of Irish players throughout the second half of the twentieth century. However, it was the inclusion of Irish teenagers within the youth policies of the largest clubs in the period after the 1970s that marked a break from the traditional pattern of buyer-supplier relations. Instead of continuing to purchase players who had established reputations within the Irish leagues, English clubs began to hire the most promising schoolboys before they joined Irish sides. As this practice spread, it eventually eliminated a valuable source of income: the selling of players to English clubs. Despite this development it would, however, be inappropriate to view the relationship between the Irish and English football industries as a simple zero sum game as Irish clubs benefit from employing highly trained young players who return home after failing to establish careers in England.

Community-Level Inequalities in Concussion Education of Youth Football Coaches.

PubMed

Kroshus, Emily; Kerr, Zachary Y; Lee, Joseph G L

2017-04-01

USA Football has made the Heads Up Football (HUF) concussion education program available for coaches of youth football players. Existing evidence about the effectiveness of the HUF coach education program is equivocal. For HUF and other programs, there is growing concern that even effective interventions can increase inequalities if there is different uptake or impact by SES or other demographic factors. Understanding how adoption is patterned along these lines is important for understanding equity issues in youth football. This study tested the hypothesis that there will be lower adoption of HUF among coaches of youth football players in lower-SES communities. The authors conducted a cross-sectional study of the association between community-level characteristics and number of USA Football youth league coaches who have completed HUF. Data were collected in 2014 and analyzed in 2015-2016. Implementation of the HUF program was patterned by community-level socioeconomic characteristics. Leagues located in communities with a higher percentage of families with children aged <18 years living below the poverty line and a smaller percentage of non-Hispanic white residents tended to have leagues with smaller percentages of HUF-certified coaches. As interventions are developed that reduce the risks of youth football, it is important to consider not just the effectiveness of these interventions, but also whether they reduce or exacerbate health inequities. These results suggest that relying on voluntary adoption of coach education may result in inequitable implementation. Further study is required to identify and remedy organizational and contextual barriers to implementation of coach education in youth sport. Copyright © 2017 American Journal of Preventive Medicine.

Fernandes, JFT, Lamb, KL, and Twist, C. A comparison of load-velocity and load-power relationships between well-trained young and middle-aged males during 3 popular resistance exercises. J Strength Cond Res 32(5): 1440-1447, 2018-This study examined the load-velocity and load-power relationships among 20 young (age 21.0 ± 1.6 years) and 20 middle-aged (age 42.6 ± 6.7 years) resistance-trained males. Participants performed 3 repetitions of bench press, squat, and bent-over-row across a range of loads corresponding to 20-80% of 1 repetition maximum (1RM). Analysis revealed effects (p < 0.05) of group and load × group on barbell velocity for all 3 exercises, and interaction effects on power for squat and bent-over-row (p < 0.05). For bench press and bent-over-row, the young group produced higher barbell velocities, with the magnitude of the differences decreasing as load increased (ES; effect size 0.0-1.7 and 1.0-2.0, respectively). Squat velocity was higher in the young group than the middle-aged group (ES 1.0-1.7) across all loads, as was power for each exercise (ES 1.0-2.3). For all 3 exercises, both velocity and 1RM were correlated with optimal power in the middle-aged group (r = 0.613-0.825, p < 0.05), but only 1RM was correlated with optimal power (r = 0.708-0.867, p < 0.05) in the young group. These findings indicate that despite their resistance training, middle-aged males were unable to achieve velocities at low external loads and power outputs as high as the young males across a range of external resistances. Moreover, the strong correlations between 1RM and velocity with optimal power suggest that middle-aged males would benefit from training methods which maximize these adaptations.

Sex Hormone Influence on Hepatitis in Young Male A/JCr Mice Infected with Helicobacter hepaticus▿ †

PubMed Central

Theve, Elizabeth J.; Feng, Yan; Taghizadeh, Koli; Cormier, Kathleen S.; Bell, David R.; Fox, James G.; Rogers, Arlin B.

2008-01-01

Hepatitis B virus (HBV), the leading cause of human hepatocellular carcinoma, is especially virulent in males infected at an early age. Likewise, the murine liver carcinogen Helicobacter hepaticus is most pathogenic in male mice infected before puberty. We used this model to investigate the influence of male sex hormone signaling on infectious hepatitis. Male A/JCr mice were infected with H. hepaticus or vehicle at 4 weeks and randomized into surgical and pharmacologic treatment groups. Interruption of androgen pathways was confirmed by hormone measurements, histopathology, and liver gene and Cyp4a protein expression. Castrated males and those receiving the competitive androgen receptor antagonist flutamide had significantly less severe hepatitis as determined by histologic activity index than intact controls at 4 months. Importantly, the powerful androgen receptor agonist dihydrotestosterone did not promote hepatitis. No effect on hepatitis was evident in males treated with the 5α-reductase inhibitor dutasteride, the peroxisome proliferator-activated receptor-α agonist bezafibrate, or the nonsteroidal anti-inflammatory drug flufenamic acid. Consistent with previous observations of hepatitis-associated liver-gender disruption, transcriptional alterations involved both feminine (cytochrome P450 4a14) and masculine (cytochrome P450 4a12 and trefoil factor 3) genes, as well gender-neutral (H19 fetal liver mRNA, lipocalin 2, and ubiquitin D) genes. Hepatitis was associated with increased unsaturated C18 long-chain fatty acids (oleic acid and linoleic acid) relative to saturated stearic acid. Our results indicate that certain forms of androgen interruption can inhibit H. hepaticus-induced hepatitis in young male mice, whereas androgen receptor agonism does not worsen disease. This raises the possibility of targeted hormonal therapy in young male patients with childhood-acquired HBV. PMID:18559427

2015-01-02

On August 4, 2014, the Acute Communicable Disease Control Program of the Los Angeles County Department of Public Health received a report of three aseptic meningitis cases among football players at a county high school. An investigation was conducted to determine the extent of the outbreak, identify potential exposures, and recommend control measures. An outbreak-associated aseptic meningitis case was defined as an illness of any team or family member with onset during July 28-August 11 with 1) cerebrospinal fluid pleocytosis and negative bacterial culture or 2) an emergency department visit with headache, fever, and stiff neck. Ten cases were identified; nine in males, and one in a female; patient ages ranged from 13 to 17 years. All the patients sought care at an emergency department, and five were hospitalized, resulting in 12 total hospital days. All 10 patients have recovered. Eight patients were football players, and two were siblings of football players. The most affected subgroup was the junior varsity football team, with seven cases out of 57 players (attack rate = 12.3%); the relative risk for aseptic meningitis was higher among players who were linemen than among those who were not linemen (relative risk = 5.4 [p = 0.03]). Of the 10 patients, eight tested positive by polymerase chain reaction for enterovirus, and two were not tested. Echovirus testing was performed at the California Viral and Rickettsial Disease Laboratory. Of the eight specimens testing positive for enterovirus, seven tested positive for echovirus 30, and one specimen could not be typed because of insufficient quantity.

Tactical expertise assessment in youth football using representative tasks.

PubMed

Serra-Olivares, Jaime; Clemente, Filipe Manuel; González-Víllora, Sixto

2016-01-01

Specific football drills improve the development of technical/tactical and physical variables in players. Based on this principle, in recent years it has been possible to observe in daily training a growing volume of small-sided and conditioned games. These games are smaller and modified forms of formal games that augment players' perception of specific tactics. Despite this approach, the assessment of players' knowledge and tactical execution has not been well documented, due mainly to the difficulty in measuring tactical behavior. For that reason, this study aims to provide a narrative review about the tactical assessment of football training by using representative tasks to measure the tactical expertise of youth football players during small-sided and conditioned games. This study gives an overview of the ecological approach to training and the principles used for representative task design, providing relevant contribution and direction for future research into the assessment of tactical expertise in youth football.

"Deflategate": Time, Temperature, and Moisture Effects on Football Pressure

2016-09-01

In a recent paper in TPT, DiLisi and Rarick used the National Football League "Deflategate" controversy to introduce to physics students the physics of a bouncing ball. In this paper, we measure and analyze the environmental effects of time, ambient temperature, and moisture on the internal pressure of an NFL football. We focus on the rate of pressure recovery that occurs when a cold football (either wet or dry) is returned to the warm locker room environment where the pressure was initially measured. Both studies stem from the so-called NFL "Deflategate" controversy in which footballs that initially met a minimum internal pressure requirement were rechecked at halftime of the AFC Championship game, and in some cases were reported to have fallen below the minimum pressure requirement. The question is whether the pressure changes were due to environmental exposure or rather to some air being released from the balls, or both.

Return to play guidelines cannot solve the football-related concussion problem.

PubMed

Johnson, L Syd M

2012-04-01

High school football players are the single largest cohort of athletes playing tackle football, and account for the majority of sport-related concussions. Return to play guidelines (RTPs) have emerged as the preferred approach for addressing the problem of sport-related concussion in youth athletes. This article reviews evidence of the risks and effects of football-related concussion and subconcussive brain trauma, as well as the effectiveness of RTPs as a preventative measure. Literature review utilized PubMed and Google Scholar, using combinations of the search terms "football,"sports,"concussion,"Chronic Traumatic Encephalopathy,"athlete,"youth," and "pediatric." Literature review emphasized medical journals and primary neuroscientific research on sport-related concussion and concussion recovery, particularly in youth athletes. Sport-related concussion is a significant problem among student athletes. Student athletes are more vulnerable to concussion, and at risk of neurocognitive deficits lasting a year or more, with serious effects on academic and athletic performance. RTPs do little to address the problem of sport-related concussion or the chronic damage caused by subconcussive brain trauma. Emphasizing RTPs as the solution to the concussion problem in tackle football risks neglecting genuine reforms that would prevent concussions. More effective concussion prevention is needed. Eliminating tackling from school football for youth under 16 is recommended to reduce concussions. Additional modifications to football are recommended to enhance safety and reduce brain trauma at all levels of play. © 2012, American School Health Association.

Cognitive behavioral therapy to reduce overt aggression behavior in Chinese young male violent offenders.

2014-01-01

This 9-week study was designed to determine whether a commercial cognitive-behavioral training program could effectively reduce overt aggression behavior in Chinese young male violent offenders. Sixty-six participants were randomly assigned to receive routine intervention alone (control group) or routine intervention plus Williams LifeSkills Training (WLST group) in a 1:1 ratio. The primary outcome was change scores on the Modified Overt Aggression Scale (MOAS) from baseline to one week following end of training. Secondary outcomes were change scores on the Barratt Impulsiveness Scale-11 (BIS-11) and Cook-Medley Hostility Scale (CMHS). There were significant between-group differences in change of MOAS total score (P < .001) and all sub-scores (Ps < .01) except aggression against property. Between-group differences were also observed in change of BIS-11 and CMHS total score (Ps < 0.05). All results favored the WLST group. These findings suggest WLST has the potential to be an effective intervention to reduce overt aggressive behavior in young male violent offenders. © 2013 Wiley Periodicals, Inc.

The globalization of football: a study in the glocalization of the 'serious life'.

Giulianotti, Richard; Robertson, Roland

2004-12-01

Sport, in particular football, constitutes one of the most dynamic, sociologically illuminating domains of globalization. This paper examines the globalization of football with particular reference to Robertson's theorizations of global processes. We examine football's cultural globalization through the concept of 'glocalization', which highlights the interdependence of local and global processes within the game's identities and institutions. We address economic globalization in football by considering the world's leading clubs as 'glocal' transnational corporations. We assess the political globalization of football with reference to the possible enhancement of democracy within the game's international governance. We conclude by affirming the utility of sport in advancing our empirical and theoretical understanding of globalization processes.

Methods The authors manually reviewed the result of Korean military multiphasic personal inventory (KMPI) in the examination of conscription in Korea from January 2008 to May 2010. There were total 237 young males in this review. Normal volunteers group (n=150) was composed of those who do not have history of brain disease or brain trauma. Brain disease group (n=33) was consisted of those with history of brain disease. Brain trauma group (n=54) was consisted of those with history of brain trauma. The results of KMPI in each group were compared. Results Abnormal results of KMPI were found in both brain disease and trauma groups. In the brain disease group, higher tendencies of faking bad response, anxiety, depression, somatization, personality disorder, schizophrenic and paranoid psychopathy was observed and compared to the normal volunteers group. In the brain trauma group, higher tendencies of faking-good, depression, somatization and personality disorder was observed and compared to the normal volunteers group. Conclusion Young male with history of brain disease or brain trauma may have higher tendencies to have abnormal results of multiphasic personal inventory test compared to young male without history of brain disease or brain trauma, suggesting that damaged brain may cause psychopathology in young male group in Korea.

Keen, ML, Miller, KC, and Zuhl, MN. Thermoregulatory and perceptual effects of a percooling garment worn underneath an American football uniform. J Strength Cond Res 31(11): 2983-2991, 2017-American football athletes are at the highest risk of developing exertional heat illness (EHI). We investigated whether percooling (i.e., cooling during exercise) garments affected perceptual or physiological variables in individuals exercising in the heat while wearing football uniforms. Twelve male participants (age = 24 ± 4 year, mass = 80.1 ± 8.5 kg, height = 182.5 ± 10.4 cm) completed this cross-over, counterbalanced study. On day 1, we measured peak oxygen consumption (V[Combining Dot Above]O2). On days 2 and 3, participants wore percooling garments with (ICE) or without (CON) ice packs over the femoral and brachial arteries. They donned a football uniform and completed 3, 20-minute bouts of treadmill exercise at ∼50% of peak V[Combining Dot Above]O2 (∼33° C, ∼42% relative humidity) followed by a 10-minute rest period. Ice packs were replaced every 20 minutes. Rating of perceived exertion (RPE), thermal sensation, and thirst sensation were measured before and after each exercise bout. Environmental symptoms questionnaire (ESQ) responses and urine specific gravity (Usg) were measured pretesting and after the last exercise bout. V[Combining Dot Above]O2, change in heart rate (ΔHR), and change in rectal temperature (ΔTrec) were measured every 5 minutes. Sweat rate, sweat volume, and percent hypohydration were calculated. No interactions (F17,187 ≤ 1.6, p ≥ 0.1) or main effect of cooling condition (F1,11 ≤ 1.4, p ≥ 0.26) occurred for ΔTrec, ΔHR, thermal sensation, thirst, RPE, ESQ, or Usg. No differences between conditions occurred for sweat volume, sweat rate, or percent hypohydration (t11 ≤ 0.7, p ≥ 0.25). V[Combining Dot Above]O2 differed between conditions over time (F15,165 = 3.3, p < 0.001); ICE was lower than CON at 30, 55, and 70 minutes (p �

Concussions in American Football.

PubMed

Womble, Melissa N; Collins, Michael W

Major advancements in sport-related concussion (SRC) management have been made across time to improve the safety of contact sports, including football. Nevertheless, these advances are often overlooked due to concerns regarding the potential long-term effects of SRC. Although further research is needed, it is critical that current efforts are focused on better understanding SRC in order to recognize and change ongoing factors leading to prolonged recoveries, increased risk for injury, and potentially long-term effects. To reduce risk for these outcomes, future focus must be placed on increased education efforts, immediate reporting of injury, prevention techniques, targeted treatment, and the development of multidisciplinary treatment teams nationwide. Finally, with the progress in understanding concussion, it is important to remain vigilant of additional advances that will help to further improve the safety of contact sports, including football.

The purpose of this study was to examine the effect of specific endurance (Yo-Yo Intermittent recovery test level 1, Yo-Yo IR1) on match performance in male youth soccer. Twenty-one young, male soccer players (age 14.1 +/- 0.2 years) were involved in the study. Players were observed during international championship games of corresponding age categories and completed the Yo-Yo IR1 on a separate occasion. Physical (distance coverage) and physiological match demands were assessed using Global Positioning System technology and heart rate (HR) short-range telemetry, respectively. During the match (two 30-minutes halves), players covered 6,204 +/- 731 m, of which 985 +/- 362 m (16%) were performed at high intensities (speed >13 kmxh, HIA). A significant decrement (3.8%, p = 0.003) in match coverage was evident during the second half. No significant (p = 0.07) difference between halves was observed for HIA (p = 0.56) and sprint (speed >18 kmxh, SPR) distances. During the first and second halves, players attained the 86 +/- 5.5 and 85 +/- 6.0% of HRmax (p = 0.17), respectively. Peak HR during the first and second halves were 100 +/- 4 and 99.4 +/- 4.7% of HRmax, respectively. Yo-Yo IR1 performance (842 +/- 352 m) was significantly related to match HIA (r = 0.77, p < 0.001) and total distance (r = 0.65, p = 0.002). This study's results showed that specific endurance, as determined by Yo-Yo IR1 performance, positively affects physical match performance in male young soccer players. Consequently, the Yo-Yo IR1 test may be regarded as a valid test to assess game readiness and guide training prescription in male youth soccer players.

Vitamin D is synthesised in the skin during exposure to sunlight and its fundamental roles are the regulation of calcium and phosphate metabolism and bone mineralisation. The aim of our study was to evaluate serum levels of 25-hydroxyvitamin D3, PTH and bone turnover markers (P1NP, OC, beta-CTx, OC/beta-CTx) and the intake of calcium and vitamin D in Polish Professional Football League (Ekstraklasa) players and in young men with a low level of physical activity. Fifty healthy men aged 19 to 34 years were included in the study. We showed that 25(OH)D3 and P1NP levels and OC/beta-CTx were higher in the group of professional football players than in the group of physically inactive men. The daily vitamin D and calcium intake in the group of professional football players was also higher. We showed a significant relationship between 25(OH)D3 levels and body mass, body cell mass, total body water, fat-free mass, muscle mass, vitamin D and calcium intake. Optimum 25(OH)D3 levels were observed in a mere 16.7% of the football players and vitamin D deficiency was observed in the physically inactive men. The level of physical activity, body composition, calcium and vitamin D intake and the duration of exposure to sunlight may significantly affect serum levels of 25(OH)D3.

What’s in a game? A systems approach to enhancing performance analysis in football

PubMed Central

2017-01-01

Purpose Performance analysis (PA) in football is considered to be an integral component of understanding the requirements for optimal performance. Despite vast amounts of research in this area key gaps remain, including what comprises PA in football, and methods to minimise research-practitioner gaps. The aim of this study was to develop a model of the football match system in order to better describe and understand the components of football performance. Such a model could inform the design of new PA methods. Method Eight elite level football Subject Method Experts (SME’s) participated in two workshops to develop a systems model of the football match system. The model was developed using a first-of-its-kind application of Cognitive Work Analysis (CWA) in football. CWA has been used in many other non-sporting domains to analyse and understand complex systems. Result Using CWA, a model of the football match ‘system’ was developed. The model enabled identification of several PA measures not currently utilised, including communication between team members, adaptability of teams, playing at the appropriate tempo, as well as attacking and defending related measures. Conclusion The results indicate that football is characteristic of a complex sociotechnical system, and revealed potential new and unique PA measures regarded as important by SME’s, yet not currently measured. Importantly, these results have identified a gap between the current PA research and the information that is meaningful to football coaches and practitioners. PMID:28212392

Objectives: To determine whether football results are associated with mortality from circulatory disease. Design: Retrospective study, comparing mortality on days of football matches between 18 August 1994 and 28 December 1999 with the results of the football matches. Setting: Newcastle and North Tyneside, Sunderland, Tees, and Leeds Health Authority areas of England. Subjects: All persons resident in Newcastle and North Tyneside, Sunderland, Tees, and Leeds Health Authority areas of England. Main outcome measures: Mortality attributable to acute myocardial infarction and stroke. Results: On days when the local professional football team lost at home, mortality attributable to acute myocardial infarction and stroke increased significantly in men (relative risk 1.28, 95% confidence intervals 1.11 to 1.47). No increase was observed in women. Conclusions: Results achieved by the local professional football team are associated systematically with circulatory disease death rates over a five year period in men, but not women. PMID:12775788

Metabolic syndrome is a clustering of symptoms associated with abdominal obesity that demonstrates a high risk for cardiovascular disease and type II diabetes mellitus. To evaluate football linemen in National Collegiate Athletic Association Divisions I, II, and III schools for the presence of metabolic syndrome according to the American Heart Association/National Heart, Lung, and Blood Institute criteria as well as to document other related biomarkers. Cross-sectional descriptive study. Three university locations on the first full day of football camp in early morning. Of 76 football linemen, 70 were able to provide blood samples. Height, mass, blood pressure, upper-body skinfolds, and waist circumference were measured at various stations. Two small venous samples of blood were collected and analyzed in a hospital laboratory for fasting insulin, glucose, high-density lipoprotein, total cholesterol, triglycerides, C-reactive protein, and glycosylated hemoglobin. The last station was a verbal family history for cardiovascular disease and diabetes; also, athletes filled out a nutrition attitudes questionnaire. Of the 70 athletes, 34 were identified as having metabolic syndrome according to measures of blood pressure, waist circumference, fasting glucose, high-density lipoprotein, and triglycerides. The mean total cholesterol-to-high-density lipoprotein cholesterol ratio for the group was 4.95, with 32 participants displaying values higher than 5.0. Twelve volunteers had total cholesterol levels greater than 200 mmol/L, 15 had high levels of C-reactive protein, and 9 had slightly elevated levels of glycosylated hemoglobin. Although athletes might be assumed to be protected from risks of cardiovascular disease, we found a high incidence of metabolic syndrome and other associated adverse biomarkers for heart disease in collegiate football linemen. Early screening, awareness, and intervention may have favorable effects on the overall health outcomes of football linemen.

Ultrasound (US)-guided percutaneous needle electrolysis (PNE) is a novel minimally invasive approach, which involves the application of a galvanic current via an acupuncture needle. As in any procedure involving needling, vagal reactions have been reported during PNE. To examine for changes in autonomic activity during the US-guided PNE technique on healthy patellar tendons by measurement and analysis of heart rate variability (HRV). Twenty-two male footballers were randomly allocated to: a control group (11 players), for whom HRV was recorded for 10 min, both at rest and during an exhaustive US examination of the patellar tendon and adjacent structures; and an experimental group (11 players), for whom HRV was recorded for 10 min, both at rest and during application of US-guided PNE on the patellar tendon. The following HRV parameters were assessed: mean NN interval, mean heart rate, time domain parameters (SDNN, rMSSD, pNN50), diameters of the Poincaré plot (SD1, SD2), stress score, and sympathetic/parasympathetic ratio. There were no differences between groups in any baseline measurements, nor were there any significant differences between control group measurements (baseline vs intervention). The experimental group exhibited statistically significant increases in SDNN/SD1 (p=0.02/p=0.03) and SD2 (p=0.03), indicating increased parasympathetic and decreased sympathetic activity, respectively. US-guided PNE was associated with an autonomic imbalance characterised by greater parasympathetic activity, which could potentially result in a vasovagal reaction. Care should be taken to monitor for adverse reactions during US-guided PNE and simple HRV indicators may have a role in early detection. Published by the BMJ Publishing Group Limited.

In the United States, black women are at much greater risk for obesity than black men. We explored whether adolescent behaviors (family dinners, hours of television, playing sports with mother, playing sports with father, bouts of physical activity) were associated with gender disparity in 6-year obesity incidence in young adulthood. We used data from the nationally representative National Longitudinal Study of Adolescent Health to examine adolescent behaviors in nonimmigrant black (n = 1,503) and white (n = 4,452) youths in 1994-95 (aged 11-19 years) and 1995-96 (aged 12-20). We assessed gender disparity in obesity incidence (female incidence minus male incidence) during young adulthood (2001-02; aged 18-26). Standardized gender disparities were calculated using race- and gender-stratified, covariate-adjusted logistic regression models in which males and females were set to the same distributions of adolescent behaviors. In adolescence, black females reported less leisure-time physical activity and lower likelihood of playing sports with either parent compared with black males. Setting adolescent behaviors equal for black males and females did not reduce the estimated gender disparity in obesity incidence (nonstandardized: 9.8 percentage points (95% confidence interval (CI): 4.5, 15.1); fully standardized: 10.2 percentage points (5.2, 15.2)). There was little gender disparity in whites before or after adjustments. To our knowledge, this is the first study to examine to what extent behavioral differences during adolescence might account for gender disparity in obesity incidence in black young adults. Male-female differences in these adolescent behaviors did not appear to underlie the gender gap in young adult obesity.

To describe creatine supplementation patterns and behaviors associated with creatine supplementation in high school football players. A cross-sectional, multisite, anonymous, descriptive survey was conducted between October 1999 and February 2000. 37 public high schools in Wisconsin. A total of 1,349 high school football players, grades 9-12. Self-reported prevalence of creatine use, as well as perceived benefits and risks. In addition, sources of information and influence regarding creatine supplementation were assessed. 30% of the respondents reported using creatine. Creatine use was lowest in the 9th grade (10.4%) and highest in the 12th grade (50.5%). 41% of the players at small schools stated they used creatine compared with 29% of the players in large schools. Enhanced recovery following a workout was the most likely perceived benefit of creatine supplementation, while dehydration was cited most often as a risk of creatine use. Users were encouraged to take creatine most often by their friends while their parents discouraged creatine use. Creatine use is widespread in high school football players. High school football players who use creatine may not be aware of the risks and benefits associated with creatine supplementation. Sports medicine professionals who work with this population need to educate athletes, coaches, and parents about the use of creatine as a performance-enhancing supplement.

In common with elite athletes from other sport disciplines, severe or recurrent injuries in professional footballers are considered to be major physical and psychosocial stressors, which may predispose to mental health problems during and after their career. To determine the prevalence of mental health problems and psychosocial difficulties in current and former professional footballers, and to explore the association between psychosocial stressors and the health conditions studied. Based on validated scales, a paper and electronic questionnaire was developed for current and former professional footballers and distributed by the World Footballers' Union (FIFPro) and players' unions in six countries. Prevalence was calculated and cross-sectional analyses were conducted. The response rate was 29% with 253 responses available for analysis. The prevalence of mental health complaints ranged from 5% (burnout) to 26% (anxiety/depression) in 149 current players and from 16% (burnout) to 39% (anxiety/depression) in 104 former footballers. The prevalence of psychosocial problems ranged from 3% (low self-esteem) to 26% (adverse nutrition behaviour) in current players and from 5% (low self-esteem) to 42% (adverse nutrition behaviour) in former footballers. In both current and former players, mental health problems were significantly associated with low social support (odds ratio [OR] = 1.1) and recent life events (OR = 1.4-1.6). In former players, previous surgery was significantly associated with smoking (OR = 1.9). The prevalence of mental health problems and/or psychosocial difficulties in current and former professional footballers was found to be high. The presence of mental health problems was associated with low social support and recent life events. © The Author 2015.

The epidemiology of injury in Paralympic football has received little attention. A study of all sports at the London 2012 Paralympic Games identified football 5-a-side as the sport with the highest injury rate, meriting further detailed analysis, which may facilitate the development of strategies to prevent injuries. To examine the injury rates and risk factors associated with injury in Paralympic football. Secondary analysis of a prospective cohort study of injuries to football 5-a-side and football 7-a-side athletes. London 2012 Paralympic Games. Participants included 70 football 5-a-side athletes and 96 football 7-a-side athletes. Athletes from all but one country chose to participate in this study. The Paralympic Injury and Illness Surveillance System was used to track injuries during the Games, with data entered by medical staff. Injury incidence rate (IR) and injury incidence proportion (IP). The overall IR for football 5-a-side was 22.4 injuries/1000 athlete-days (95% confidence interval [CI], 14.1-33.8) with an IP of 31.4 injuries per 100 athletes (95% CI, 20.9-43.6). In 5-a-side competition, 62.5% of injuries were associated with foul play. The overall IR for football 7-a-side was 10.4 injuries/1000 athlete-days (95% CI, 5.4-15.5), with an IP of 14.6 injuries per 100 athletes (95% CI, 7.5-21.6). The most commonly injured body region in both sports was the lower extremity. To our knowledge, this study is the first to examine IR and risk factors associated with injury in Paralympic football. Future studies are needed to determine mechanisms of injury and independent risk factors for injury, thus informing prevention strategies.

Purpose Few reports have documented psychopathological abnormalities in patients with primary spontaneous pneumothorax (PSP). We analyzed the results of a multiphasic personal inventory test to investigate the psychopathologic impact of PSP in young Korean males. Materials and Methods The authors reviewed the results of a Korean military multiphasic personal inventory (KMPI) administered to military conscripts in South Korea. A total of 234 young males participated in this study. The normal volunteer group (n=175) comprised individuals who did not have any lung disease. The PSP group (n=59) included individuals with PSP. None of the examinees had any psychological problems. The KMPI results of both groups were compared. Results There were more abnormal responses in the PSP group (17.0%) than the normal volunteer group (9.1%, p=0.002). The anxiety scale and depression scale scores of the neurosis category were greater for the PSP group than the normal group (p=0.039 and 0.014, respectively). The personality disorder and paranoia scale scores of the psychopathy category were greater for the PSP group than the normal group (p=0.007 and 0.018, respectively). Conclusion Young males with PSP may have greater tendencies to suffer from anxiety, depression, personality disorders, and paranoia compared to normal individuals. Clinicians should be advised to evaluate the psychopathological aspects of patients with PSP. PMID:22869471

To analyze the extent and characteristics of injuries and musculoskeletal complaints in elite football referees and to analyze differences between match and assistant referees. Retrospective cohort study. Training camp organized by the Swiss Referees Association. All 71 referees of the 2 top divisions of the Swiss Football League (2005-2006 season). The referees (66 males and 5 females) completed a questionnaire on their personal characteristics, referee qualifications, time spent in training and matches, career history of injuries, and musculoskeletal complaints caused by training or refereeing and were subsequently interviewed about the location, type, circumstances, and consequences of reported injuries. Incidence of injuries, frequency of musculoskeletal complaints, type of injuries, and complaints. A total of 41 injuries during the career were reported by 31 of 71 referees (44%). Injuries were incurred more frequently in training than during matches, and all injuries reported resulted in at least 2 weeks of absence from sport. About a quarter of the referees reported an injury, and almost 90% of the referees reported musculoskeletal complaints caused by refereeing during the preceding 12 months. In male referees, hamstring strains and ankle sprains were the most common injuries, and the hamstrings, knee, Achilles tendon, and calf were the most prevalent locations of musculoskeletal complaints. No significant difference in the incidence of injury or in the frequency of complaints was observed between match and assistant referees. Future studies should be designed prospectively and should include a larger group of female referees. Regarding the incidence of injuries and frequency of musculoskeletal complaints related to refereeing, prevention programs for football referees should be developed, evaluated, and implemented.

To survey high school American football programs regarding current prevention measures for reducing heat injuries during the football season. Web-based survey of 27 questions based on consensus statement guidelines by the American College of Sports Medicine on reducing heat injury risk in youth football. National (United States) and community-based. High school programs receiving survey distribution from their state athletic association and the National Federation of State High School Associations. Responses (percentage and incidence) to questions on preseason acclimatization procedures, practice modification protocols, preparticipation risk factors, hydration management strategies, rest period strategies, heat injury education and policies, and preparation for heat-related emergency care. A total of 540 high school football programs from 26 states completed the survey. The reported number of preseason heat injuries per program (1.38+/-2.08) was greater (P<0.001) compared to during the regular season (0.98+/-1.84). Programs modified equipment configurations during preseason (no helmets or pads, 31.3%; just helmets, 57.0%; helmets and shoulder pads only, 33.5%) or altered the practice schedule when there was excessive heat. Hydration management, education, and preparation for dealing with an acute heat injury varied among programs. Greater implementation of effective prevention measures to reduce the incidence of heat-related injury and death in high school American football is needed. Strategies should focus on modifying practices appropriately on a day-to-day basis to minimize heat strain and optimize hydration, identifying and educating at-risk individuals during the preparticipation period, and developing an emergency action plan for effectively managing heat injuries.

The prevention, early diagnosis and treatment of onychomycosis is of great importance for professional athletes to avoid physical limitations by complications. So far, there is only little data on the prevalence of dermatomycosis in professional athletes. The aim of the study was to detect the prevalence of dermatomycosis in professional football players compared to the general population. The prospective, non-interventional, controlled study on the prevalence of dermatomycosis in professional football players was carried out on football players of a German Bundesliga team compared with a previously studied, equivalently aged German working population. A questionnaire survey, a dermatological check-up and a microbiological detection of pathogens in cases of suspicion were performed. Data of 84 football players (n = 45 in 2013; n = 39 in 2015) were compared to data of n = 8186 male employees between 17 and 35 years of age. In the group of athletes, there were findings of 60.7% onychomycosis, 36.9% of tinea pedis and 17.8% of pityriasis versicolor. In the group of the age-equivalent general German working population the findings were: onychomycosis 3.3%, tinea pedis 3.2%, pityriasis versicolor 1.4%. Our study shows a clearly higher risk for fungal diseases of the skin especially on the feet of professional football players. The results show a necessity for elucidation within prevention and the establishment of an appropriate therapy of dermatomycosis for professional football players.

Intervention Eleven 90 min sessions, each divided into two 45 min halves of Play Football (football skills) and Play Fair (health issues), each session focused on one specific health risk factor. Main outcome measures Health knowledge using a 20-item questionnaire; coaches' attitudes towards their training programme using a 10-item questionnaire and children's attitudes towards the health education programme using a six-item questionnaire. Results Children in the Grade 7 intervention group showed significant (p<0.05) increases in the proportion of correct responses for nine of the 20 health knowledge questions postintervention, and these increases were maintained at 3 months postintervention. The Grade 6 intervention group showed significant increases in the proportion of correct responses for 15 of the 20 health knowledge questions postintervention. The Grade 7 control group showed a significant increase in the proportion of correct responses to one of the 20 health knowledge questions post-Play Football sessions and nine of 20 questions post-Play Fair sessions. Over 90% of the children provided positive attitude responses to the health-education programme. Conclusions The programme demonstrated that it was possible to implement a football-based health-education programme for children in Africa that achieved significant increases in health knowledge and that was also well received by participants.

Sudden cardiac death is the most common cause of unnatural death in football. To prevent and urgently manage sudden cardiac arrest on the football field-of-play, F-MARC (FIFA Medical and Research Centre) has been fully committed to a programme of research, education, standardisation and practical implementation. This strategy has detected football players at medical risk during mandatory precompetition medical assessments. Additionally, FIFA has (1) sponsored internationally accepted guidelines for the interpretation of an athlete's ECG, (2) developed field-of-play-specific protocols for the recognition, response, resuscitation and removal of a football player having sudden cardiac arrest and (3) introduced and distributed the FIFA medical emergency bag which has already resulted in the successful resuscitation of a football player who had a sudden cardiac arrest on the field-of-play. Recently FIFA, in association with the Institute of Sports and Preventive Medicine in Saarbrücken, Germany, established a worldwide Sudden Death Registry with a view to documenting fatal events on the football field-of-play. These activities by F-MARC are testimony to FIFA's continued commitment to minimising sudden cardiac arrest while playing football. PMID:25878076

This study was designed to determine concussion incidence, risk, and relative risk among middle and high school athletes participating in various sports. Data were retrospectively obtained from 10,334 athletes of 12 different sports in Hawaii. In addition to determining the overall concussion incidence, comparisons of incidence, risk, and relative risk were made according to age, sex, concussion history, sport, and football position. The overall incidence of concussion among youth athletes was 1,250 (12.1%). The relative risk for a concussion was almost two times greater in 18-year olds than in 13-year-old athletes. In comparable sports, girls had a 1.5 times higher concussion risk than boys. Athletes with a prior concussion had 3-5 times greater risk to sustain a concussion than those with no history of a concussion. Among varied sports, wrestling and martial arts had the highest relative risk of a concussion, followed by cheerleading, football, and track and field. No differences in concussion risks were found among the football players in different positions. Older youths, females, those with a history of concussion, and those participating in high contact sports were found to have higher risks of sustaining a concussion. The findings increase awareness of concussion patterns in young athletes and raise concerns regarding protective strategies and concussion management in youth sports.

Does lower birth order amplify the association between high socioeconomic status and central adiposity in young adult Filipino males?

To test the hypothesis that lower birth order amplifies the positive association between socioeconomic status and central adiposity in young adult males from a lower income, developing country context. The Cebu Longitudinal Health and Nutrition Survey is an ongoing community-based, observational study of a 1-year birth cohort (1983). 970 young adult males, mean age 21.5 years (2005). Central adiposity measured by waist circumference; birth order; perinatal maternal characteristics including height, arm fat area, age and smoking behavior; socioeconomic status at birth and in young adulthood. Lower birth order was associated with higher waist circumference and increased odds of high waist circumference, even after adjustment for socioeconomic status in young adulthood and maternal characteristics that could impact later offspring adiposity. Furthermore, the positive association between socioeconomic status and central adiposity was amplified in individuals characterized by lower birth order. This research has failed to reject the mismatch hypothesis, which posits that maternal constraint of fetal growth acts to program developing physiology in a manner that increases susceptibility to the obesogenic effects of modern environments.

Background Owing to the complexity and heterogeneity of muscle injuries, a generally accepted classification system is still lacking. Aims To prospectively implement and validate a novel muscle injury classification and to evaluate its predictive value for return to professional football. Methods The recently described Munich muscle injury classification was prospectively evaluated in 31 European professional male football teams during the 2011/2012 season. Thigh muscle injury types were recorded by team medical staff and correlated to individual player exposure and resultant time-loss. Results In total, 393 thigh muscle injuries occurred. The muscle classification system was well received with a 100% response rate. Two-thirds of thigh muscle injuries were classified as structural and were associated with longer lay-off times compared to functional muscle disorders (p<0.001). Significant differences were observed between structural injury subgroups (minor partial, moderate partial and complete injuries) with increasing lay-off time associated with more severe structural injury. Median lay-off time of functional disorders was 5–8 days without significant differences between subgroups. There was no significant difference in the absence time between anterior and posterior thigh injuries. Conclusions The Munich muscle classification demonstrates a positive prognostic validity for return to play after thigh muscle injury in professional male football players. Structural injuries are associated with longer average lay-off times than functional muscle disorders. Subclassification of structural injuries correlates with return to play, while subgrouping of functional disorders shows less prognostic relevance. Functional disorders are often underestimated clinically and require further systematic study. PMID:23645834

Gynecomastia is defined as a palpable enlargement of the mammary gland in males that is distinguishable from lipomastia. The aim of this study was to assess the prevalence and characteristics of different causes of breast enlargement in young males referred to our tertiary center, and evaluation of the factors associated with gynaecomastia. One hundred thirty-five male recruits aged 20-30 years were enrolled in the study. A control group comprising 32 age-matched healthy individuals aged 20-25 years was also studied. Idiopathic gynecomastia (IG) was diagnosed in 31 of 135 patients (23%) and Klinefelter' syndrome (KS) was diagnosed in 70 cases (52%). Patients with KS had significantly higher body mass index (BMI) and waist and hip circumference waist/hip ratio than the control group. FSH, LH and SHBG were significantly higher and DHEAS, free testosterone (fT) and total testosterone (tT) were lower in patients with KS than the control group. Anthropometric measurements revealed significant increase in body weight and BMI in patients with IG compared with healthy controls. FSH and LH levels were significantly higher in the patients with IG. Patients with pseudogynecomastia alone were not obese and hypogonadism was observed in 35.1% of patients. We concluded that gynaecomastia in young adult males is mostly because of KS or idiopathic in origin. IG seems to be the result of androgen resistance and in part increased aromatization because of increased adiposity. Symptoms or findings for hypogonadism must be evaluated carefully in patients with pseudogynecomastia. We also suggest that the presence of both gynecomastia and azoospermia necessitate further karyotypic analyses for KS.

More than a third of young military personnel report experiencing some level of erectile dysfunction (ED). Preoccupation with body image, particularly genitals, is a distraction that can influence sexual anxiety (SA) and sexual functioning problems (SFPs), particularly ED. This study assessed the relationships between male genital self-image (MGSI), SA, and ED in a sample of male military personnel age 40 or younger. Data were from a larger study on SFPs in military populations. This sample consisted of 367 male military personnel age 40 or younger. Hierarchical regression analyses and process modeling using mediation analysis were performed to examine the effects of MGSI on ED with SA as an intermediate variable. We predicted that SA would mediate the relationship between MGSI and ED. ED severity was assessed with the International Index of Erectile Function. MGSI was assessed using the MGSI Scale. SA was assessed with the SA subscale of the Sexual Needs Scale. As hypothesized, greater satisfaction with MGSI was predictive of significantly lower SA (F[8, 352] = 4.07, P = 0.001) and lower ED (F[8, 352] = 13.20, P = 0.001). Lower levels of SA were predictive of lower levels of ED (F[8, 354] = 21.35, P < 0.001). Additionally, results also revealed a significant indirect effect of MGSI on ED through SA (b = -0.07, standard error = 0.03, confidence interval = [-0.14,-0.02], P < 0.05), indicating mediation of MGSI on ED via SA. This study underscores the complex etiologic basis of SFPs, particularly ED, and highlights the importance of considering psychologic contributors to ED, such as SA and MGSI. Strategies aimed at reducing SA may be useful in improving ED in young military populations and are worth considering as complements to strategies that improve SFPs. © 2015 International Society for Sexual Medicine.

Superficial cooling does not decrease core body temperature before, during, or after exercise in an American football uniform.

2012-12-01

The purpose of this study was to identify the effects of superficial cooling on thermoregulatory responses while exercising in a hot humid environment while wearing an American football uniform. Nine male and female subjects wore a superficial cooling garment while in a cooling (CS) experimental condition or a no cooling (NCS) control condition during an exercise task consisting of warm-up (WU), exercise (EX), and recovery (R). The exercise task simulated an American football conditioning session with subjects wearing a full American football uniform and performing anaerobic and aerobic exercises in a hot humid environment. Subjects were allowed to drink water ad libitum during rest breaks. During the WU, EX, and R periods, core body temperature (T(c)) was measured to assess the effect of the cooling garment. Neither baseline resting before warm-up T(c) nor after warm-up T(c) was significantly different between trials. No significant differences in exercise T(c) between conditions were found. Time to return to baseline T(c) revealed no significant differences between the experimental and control conditions. The authors found that the volume of fluid consumed was 34% less in the experimental condition (711.1 ± 188.0 ml) compared with the control condition (1,077.8 ± 204.8 ml). The findings indicate that the cooling garment was not effective in blunting the rise in T(c) during warm-up, attenuating a rise in T(c) during intermittent exercise, or in increasing a return to baseline T(c) during a resting recovery period in a hot humid environment while wearing an American football uniform.

2015-04-01

The aim of this study was to describe the isokinetic thigh muscle strength profile of professional male football players in Australia. Concentric (60° and 240°·s(-1)) and eccentric (30° and 120°·s(-1)) hamstrings and quadriceps isokinetic strength was measured with a HUMAC NORM dynamometer. The primary variables were bilateral concentric and eccentric hamstring and quadriceps peak torque ratios, concentric hamstring-quadriceps peak torque ratios, and mixed ratios (eccentric hamstring 30°·s(-1) ÷ concentric quadriceps 240°·s(-1)). Hamstring strength imbalance was defined as deficits in any 2 of: bilateral concentric hamstring peak torque ratio <0.86, bilateral eccentric hamstring peak torque ratio <0.86, concentric hamstring-quadriceps ratio <0.47, and mixed ratio <0.80. Fifty-five strength tests involving 42 players were conducted. Ten players (24%) were identified as having hamstring strength imbalance. Athletes with strength imbalance had significantly reduced concentric and eccentric bilateral hamstring peak torque ratios at all angular velocities tested; and reduced eccentric quadriceps peak torque (30°·s(-1)) in their stance leg, compared with those without strength imbalance. Approximately, 1 in 4 players had preseason hamstring strength imbalance; and all strength deficits were observed in the stance leg. Concentric and eccentric hamstrings strength imbalance may impact in-season football performance and could have implications for the future risk of injury.

Priorities for injury prevention in women's Australian football: a compilation of national data from different sources

Fortington, Lauren V; Finch, Caroline F

2016-01-01

Background/aim Participation in Australian football (AF) has traditionally been male dominated and current understanding of injury and priorities for prevention are based solely on reports of injuries in male players. There is evidence in other sports that indicates that injury types differ between males and females. With increasing participation in AF by females, it is important to consider their specific injury and prevention needs. This study aimed to provide a first injury profile from existing sources for female AF. Methods Compilation of injury data from four prospectively recorded data sets relating to female AF: (1) hospital admissions in Victoria, 2008/09–13/14, n=500 injuries; (2) emergency department (ED) presentations in Victoria, 2008/09–2012/13, n=1,879 injuries; (3) insurance claims across Australia 2004–2013, n=522 injuries; (4) West Australian Women's Football League (WAWFL), 2014 season club data, n=49 injuries. Descriptive results are presented as injury frequencies, injury types and injury to body parts. Results Hospital admissions and ED presentations were dominated by upper limb injuries, representing 47% and 51% of all injuries, respectively, primarily to the wrist/hand at 32% and 40%. Most (65%) insurance claim injuries involved the lower limb, 27% of which were for knee ligament damage. A high proportion of concussions (33%) were reported in the club-collected data. Conclusions The results provide the first compilation of existing data sets of women's AF injuries and highlight the need for a rigorous and systematic injury surveillance system to be instituted.

American flag football is a non-tackle, contact sport with many moderate to severe contact-type injuries reported. A previous prospective injury surveillance study by the authors revealed a high incidence of injuries to the fingers, face, knee, shoulder and ankle. The objectives of the study were to conduct a pilot-prospective injury prevention study in an attempt to significantly reduce the incidence and the severity of injuries as compared to a historical cohort, as well as to provide recommendations for a future prospective injury prevention study. A prospective injury prevention study was conducted involving 724 amateur male (mean age: 20.0 ± 3.1 years) and 114 female (mean age: 21.2 ± 7.2 years) players. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. An injury surveillance questionnaire was administered to record all time-loss injuries sustained in game sessions. There was a statistically significant reduction in the number of injured players, the number of finger/hand injuries, the incidence rate and the incidence proportion between the two cohorts (p < 0.05). This one-season pilot prevention study has provided preliminary evidence that finger/hand injuries can be significantly reduced in flag football. Prevention strategies for a longer, prospective, randomised-controlled injury prevention study should include the strict enforcement of the no-pocket rule, appropriate head gear, the use of comfortable-fitting ankle braces and mouth guards, and changing the blocking rules of the game.

Variations in ankle injury rates and distributions among competition levels are unclear, but such data may help inform strategies to prevent ankle sprains during American football. To describe the epidemiological patterns of ankle sprains in youth, high school (HS), and collegiate American football. Descriptive epidemiological study. Data regarding youth, HS, and college football athletes were collected from 3 injury surveillance programs: (1) the Youth Football Safety Study (YFSS), (2) the National Athletic Treatment, Injury and Outcomes Network (NATION), and (3) the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP). During the 2012-2014 seasons, the YFSS, NATION, and NCAA ISP included 310, 184, and 71 football team-seasons, respectively. Athletic trainers (ATs) attended each practice and game and reported injuries and athlete-exposures (AEs) via their preferred injury documentation application. Ankle sprain rates for each type of ankle sprain were calculated overall, by event type (ie, practices and games), and specifically for severe injuries (ie, participation restriction time >21 days) and recurrent injuries (as defined by ATs). Rate ratios (RRs) were used to compare ankle sprain rates by competition level and event type. Injury proportion ratios (IPRs) were used to compare differences in severity, surgical needs, recurrence, injury mechanism, and injury activity by competition level. RRs and IPRs with 95% confidence intervals excluding 1.00 were considered statistically significant. A total of 124, 897, and 643 ankle sprains were reported in youth, HS, and college football, respectively. This led to respective rates of 0.59, 0.73, and 1.19 sprains per 1000 AEs. The ankle sprain rate in college football was higher than the rates in HS (RR = 1.64; 95% CI, 1.48-1.82) and youth (RR = 2.01; 95% CI, 1.65-2.43) football. The proportion of ankle sprains that were recurrent in youth football was higher than the proportions in HS (IPR

Cervical spondylolysis (CS) is a rare condition and is even more uncommon in pediatric patients. It is characterized by a disruption of the articular mass at the junction of the superior and inferior facet joints and often is diagnosed incidentally. The C6 level is most commonly involved, and the cause of CS remains unknown. There are no recommendations in the literature regarding activity modification in patients with CS and no discussion as to risks of participation in American football or other contact sports. To report a case of C6 bilateral cervical spondylolysis with bicuspid spinous process and to discuss radiographic/clinical findings and issues related to participation in contact sports and minimizing the risk of spinal cord injury. Case report with 6 months clinical/radiographic follow-up Radiographic description, clinical findings, and current review of the literature. A pediatric patient presented with a bilateral C6 cervical spondylolysis and bicuspid spinous process after an American football-related minor cervical spine trauma. Findings on radiographs indicated that the spondylolysis appeared to be chronic in nature, without evidence of instability. The patient and his family were educated on ways to decrease the risk of spinal cord injury with contact sports, after which the patient was allowed to participate fully in sports without restrictions or adverse events. Pediatric cervical spondylolysis is a rare condition, the cause of which remains debated. Although there is theoretical risk, more than 1.5 million youth participate in American football annually, and there have been no reported cases of significant spinal cord injury in patients with CS from football or other contact sports.

As a collision sport, football carries a significant risk of injury, as indicated by the large number of pediatric football-related injuries seen in emergency departments. There is little information in the medical literature focusing on the age-related injury patterns of this sport. Our purpose was to evaluate the types of football-related injuries that occur in children and adolescents and assess which patient characteristics, if any, affect injury pattern. Retrospective chart review was performed of football-related injuries treated at a level 1 pediatric referral hospital emergency department and surrounding urgent care clinics between January 2010 and January 2014. Patients with e-codes for tackle football selected from the electronic medical record were divided into 4 age groups: younger than 8 years old, 8 to 11, 12 to 14, and 15 to 18 years. Data collected included diagnosis codes, procedure codes, and hospital admission status. Review identified 1494 patients with 1664 football-related injuries, including 596 appendicular skeleton fractures, 310 sprains, 335 contusions, 170 closed head injuries, 62 dislocations, 9 spinal cord injuries, and 14 solid organ injuries. There were 646 (43.2%) athletes with upper extremity injuries and 487 (32.6%) with injuries to the lower extremity. Hospital admissions were required in 109 (7.3%) patients. Fracture was the most common injury in all four patient age groups, but occurred at a lower rate in the 15 to 18 years old age group. The rate of soft tissue injury was higher in the 15 to 18 years old age group. The rate of closed head injury, which included concussions, was highest in the younger than 8 years old age group. Age does influence the rates of certain football-related injuries in children and adolescents. Fractures decrease with increasing age, while the rate of soft tissue trauma increases with increasing age. Younger patients (younger than 8 y old) trended toward higher rates of closed head injury compared

To review acute spinal cord injuries (ASCIs) in all Australian codes of football (rugby union [RU], rugby league [RL], Australian Rules football [ARF] and soccer) for 1997-2002 and to compare data with those of a 1986-1996 survey. Retrospective review of hospital records, and structured interviews with injured players. Patients admitted to any of the six Australian spinal cord injury units with a documented football-related ASCI over the period 1997-2002. Average annual incidence of ASCIs per 100,000 players in the different codes, final Frankel grading of injuries, and wheelchair status. Fifty-two footballers (45 adult men and seven schoolboys) suffered ASCIs between 1997 and 2002. The average annual incidence of ASCIs per 100,000 players was 3.2 for RU, 1.5 for RL, 0.5 for ARF and 0.2 for soccer. While there has been little change in incidence since the 1986-1996 survey, there has been a trend towards less severe injuries in RU and RL, but not in ARF. There have been no scrum injuries in RL since 1996, when the scrum stopped being contested. Seven injuries occurred in RU scrums, six at the moment of engagement of the opposing teams. The incidence of 2-on-1 and "gang" tackles (involving multiple tacklers) in RL is disturbing. Overall, 39% of injured players became permanently wheelchair-dependent. There continues to be good reason to revise the laws of scrum engagement in RU. The laws relating to multiple tacklers in RL should be examined. The insurance cover for injured players is grossly inadequate. The longstanding need for a registry of spinal cord injuries for all football codes regrettably remains unmet.

The aim of the present study was to examine reliability and construct convergent validity of Player Load™ (PL) from trunk-mounted accelerometry, expressed as a cumulative measure and an intensity measure (PL · min - 1 ). Fifteen male participants twice performed an overground football match simulation that included four different multidirectional football actions (jog, side cut, stride and sprint) whilst wearing a trunk-mounted accelerometer inbuilt in a global positioning system unit. Results showed a moderate-to-high reliability as indicated by the intra-class correlation coefficient (0.806-0.949) and limits of agreement. Convergent validity analysis showed considerable between-participant variation (coefficient of variation range 14.5-24.5%), which was not explained from participant demographics despite a negative association with body height for the stride task. Between-task variations generally showed a moderate correlation between ranking of participants for PL (0.593-0.764) and PL · min - 1 (0.282-0.736). It was concluded that monitoring PL ® in football multidirectional actions presents moderate-to-high reliability, that between-participant variability most likely relies on the individual's locomotive skills and not their anthropometrics, and that the intensity of a task expressed by PL · min - 1 is largely related to the running velocity of the task.

There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions. Cross-sectional study; Level of evidence, 3. Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines). In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting. © 2016 The Author(s).

J Strength Cond Res 30 (11): 3187-3193, 2016-Gaelic football is indigenous to Ireland and has similar locomotion profiles to soccer and Australian Football. Given the increasing attention on long-term player development, investigations on age-related variation in Yo-Yo intermittent recovery test level 1 (Yo-YoIR1) performance may provide useful information in talent identification, program design, and player monitoring. Therefore, the aim of this study was to evaluate Yo-YoIR1 performance across Gaelic football age groups. Male participants (n = 355) were recruited from division one, Gaelic football teams. Participants were allocated to one of the 7 groups according to respective age groups from under 13 (U13), under 14, under 15 (U15), under 16 (U16), minor, under 21 (U21), to senior age groups. Total Yo-YoIR1 distance (m) increased progressively from U13 (885 ± 347 m) to U16 (1,595 ± 380 m) equating to a rate of change of 180.2%. In comparison to U13, total distance at minor (1,206 ± 327 m) increased by 136.4%. Subsequent increases were observed in U21 (1,585 ± 445 m) and senior players (2,365 ± 489). Minimum (800-880 m) and maximum (2,240-2,280 m) total distances were comparable for U15, U16, and U21 players. Differences in total distance (m) for all age groups were statistically significant when compared to U13 players (p < 0.002). In comparison to U13 players, the magnitude of differences between age groups for total distance was deemed to be large (effect size > 0.8). Similar trends were observed for maximum velocity and estimated V[Combining Dot Above]O2max. The evolution of Yo-YoIR1 performance in Gaelic football players from adolescents to adulthood highlights how maturation may influence sport-related running ability. Changes in Yo-YoIR1 performance should be closely monitored to optimize interventions for

The aim of the study was to determine whether lifelong football training may improve cardiovascular function, physical fitness, and body composition. Our subjects were 17 male veteran football players (VPG; 68.1 ± 2.1 years) and 26 healthy age-matched untrained men who served as a control group (CG; 68.2 ± 3.2 years). Examinations included measurements of cardiac function, microvascular endothelial function [reactive hyperemic index (RHI)], maximum oxygen uptake (VO2max), and body composition. In VPG, left ventricular (LV) end-diastolic volume was 20% larger (P < 0.01) and LV ejection fraction was higher (P < 0.001). Tissue Doppler imaging revealed an augmented LV longitudinal displacement, i.e., LV shortening of 21% (P < 0.001) and longitudinal 2D strain was 12% higher (P < 0.05), in VPG. In VPG, resting heart rate was lower (6 bpm, P < 0.05), and VO2max was higher (18%, P < 0.05). In addition, RHI was 21% higher (P < 0.05) in VPG. VPG also had lower body mass index (P < 0.05), body fat percentage, total body fat mass, android fat percentage, and gynoid fat percentage (all P < 0.01). Lifelong participation in football training is associated with better LV systolic function, physical fitness, microvascular function, and a healthier body composition. Overall, VPG have better cardiovascular function compared with CG, which may reduce their cardiovascular morbidity and mortality. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Besides injury prevention, mouthguards can also be employed to improve physical performance. The effects of personalization of mouthguards have rarely been investigated. This 3-armed, randomized, controlled crossover trial investigated the difference of wearing (a) personalized or custom-made (CM, e.g., bite-aligned), (b) standard (BB, boil and bite), and (c) no (CON) mouthguards on general fitness parameters in experienced collegiate football players. A group of 10 upperclassmen (age, 19-22 years; mean ± SD: age = 20.7 ± 0.8 years; body mass = 83 ± 7.4 kg; height = 179.1 ± 5.2 cm; body mass index = 25.9 ± 2.2 kg·cm), National Collegiate Athletic Association Division II football players with at least 2 years of playing experience, were randomly assigned to the 3 mouthguard conditions: a randomized, within-subjects repeated-measures design was applied. All participants were randomly tested on strength and endurance performance V[Combining Dot Above]O2max testing, with Bruce treadmill protocol including (a) time to fatigue, (b) blood lactate concentration in millimoles per liter at stage 2 and (c) at peak fatigue, (d) flexibility, (e) reaction time, (f) squat vertical jump, (g) countermovement vertical jump, and (h) 1 repetition maximum bench press. Repeated-measures analysis of variance showed no significant differences between the 3 conditions for each outcome variable (0.23 < p < 0.94; 0.007 < (Equation is included in full-text article.)< 0.15). These data indicate that CM mouthguards did not superiorly affect general fitness parameters compared with BB and CON. In turn, protective BB or CM mouthpieces did not appear to impair general fitness performance vs. CON. The recommendation of a custom bite-aligning mouthguards for performance enhancement in young Division II football players is questioned. Further studies with larger sample sizes, gender comparison, and (sport) discipline-specific performance testing are needed.

To investigate inter and intra-tester reliability of an externally fixed dynamometry unilateral hamstring strength test, in the elite sports setting. Reliability study. Sixteen, injury-free, elite male youth football players (age=16.81±0.54 years, height=180.22±5.29cm, weight 73.88±6.54kg, BMI=22.57±1.42) gave written informed consent. Unilateral maximum isometric peak hamstring force was evaluated by externally fixed dynamometry for inter-tester, intra-day and intra-tester, inter-week reliability. The test position was standardised to correlate with the terminal swing phase of the gait running cycle. Inter and intra-tester values demonstrated good to high levels of reliability. The intra-class coefficient (ICC) for inter-tester, intra-day reliability was 0.87 (95% CI=0.75-0.93) with standard error of measure percentage (SEM%) 4.7 and minimal detectable change percentage (MDC%) 12.9. Intra-tester, inter-week reliability results were ICC 0.86 (95% CI, 0.74-0.93), SEM% 5.0 and MDC% 14.0. This study demonstrates good to high inter and intra-tester reliability of isometric externally fixed dynamometry unilateral hamstring strength testing in the regular elite sport setting involving elite male youth football players. The intra-class coefficient in association with the low standard error of measure and minimal detectable change percentages suggest that this procedure is appropriate for clinical and academic use as well as monitoring hamstring strength in the elite sport setting.

Young offenders are known to be a population with high prevalence of mental health disorders. In most cases, these disorders are neither identified nor treated properly, with the majority of them being chronic and difficult to treat. In many countries, the prevalence rates of psychopathology in male young offenders are still unknown and no psychotherapeutic interventions are delivered. Therefore, the main goal of the present study was to assess mental health problems in Portuguese male young offenders placed in either custodial or community-based programs and discuss treatment implications within the juvenile justice interventions. Participants in this study included 217 male young offenders aged between 14 and 20 years old that were randomly selected using a random number table. From the total sample, 122 (56.3 %) participants were placed in juvenile detention facilities, and 95 (43.7 %) were receiving community-based programs. Participants were interviewed with the Mini-International Neuropsychiatric Interview for Children and Adolescents, a structured interview that assesses DSM-IV Axis I Mental Disorders. Participants aged 18 years or older were also assessed with the antisocial personality disorder section from the Structured Clinical Interview for DSM-IV Axis II Personality Disorders. Results showed a high prevalence of mental health disorders, with a global prevalence of 91.2 % in the total sample. In both groups, global prevalence rates were equally high (93.4 % in youth in custodial versus 88.4 % in youth in community-based programs). Substance-related disorders were more prevalent in youth placed in juvenile facilities, whereas anxiety and mood disorders were more often found in the community-based group. Moreover, oppositional defiant disorder was more prevalent in youth from the community, whereas antisocial personality disorder and conduct disorder were less prevalent than expected in this same group. A high comorbidity rate was also found, with

In the United States, Black women are at much greater risk for obesity than Black men. We explored whether adolescent behaviors (family dinners, hours of television, playing sports with mother, playing sports with father, bouts of physical activity) were associated with gender disparity in six-year obesity incidence in young adulthood. We used data from the nationally representative National Longitudinal Study of Adolescent Health to examine adolescent behaviors in non-immigrant Black (n=1503) and White (n=4452) youths in 1994–95 (aged 11–19 years) and 1995–96 (aged 12–20). We assessed gender disparity in obesity incidence (female incidence minus male incidence) during young adulthood (2001–02; aged 18–26). Standardized gender disparities were calculated using race- and gender-stratified, covariate-adjusted logistic regression models in which males and females were set to the same distributions of adolescent behaviors. In adolescence, Black females reported less leisure-time physical activity and lower likelihood of playing sports with either parent than Black males. Setting adolescent behaviors equal for Black males and females did not reduce the estimated gender disparity in obesity incidence (non-standardized: 9.8 percentage points [95% CI: 4.5, 15.1]; fully-standardized: 10.2 percentage points [5.2, 15.2]). There was little gender disparity in Whites before or after adjustments. To our knowledge, this is the first study to examine to what extent behavioral differences during adolescence might account for gender disparity in obesity incidence in Black young adults. Male-female differences in these adolescent behaviors did not appear to underlie the gender gap in young adult obesity. PMID:19875993

Fans, homophobia and masculinities in association football: evidence of a more inclusive environment.

This article draws on 3,500 responses from fans and professionals involved in association football (soccer) to an anonymous online survey posted from June 2010 to October 2010 regarding their views towards gay footballers. The overall findings are that, contrary to assumptions of homophobia, there is evidence of rapidly decreasing homophobia within the culture of football fandom. The results advance inclusive masculinity theory with 93 per cent of fans of all ages stating that there is no place for homophobia within football. Fans blame agents and clubs for the lack of openness and challenge football's governing organizations to oppose the culture of secrecy surrounding gay players and to provide a more inclusive environment to support players who want to come out. © London School of Economics and Political Science 2012.

Abstract Youth football players may incur hundreds of repetitive head impacts (RHI) in one season. Our recent research suggests that exposure to RHI during a critical neurodevelopmental period prior to age 12 may lead to greater later-life mood, behavioral, and cognitive impairments. Here, we examine the relationship between age of first exposure (AFE) to RHI through tackle football and later-life corpus callosum (CC) microstructure using magnetic resonance diffusion tensor imaging (DTI). Forty retired National Football League (NFL) players, ages 40–65, were matched by age and divided into two groups based on their AFE to tackle football: before age 12 or at age 12 or older. Participants underwent DTI on a 3 Tesla Siemens (TIM-Verio) magnet. The whole CC and five subregions were defined and seeded using deterministic tractography. Dependent measures were fractional anisotropy (FA), trace, axial diffusivity, and radial diffusivity. Results showed that former NFL players in the AFE <12 group had significantly lower FA in anterior three CC regions and higher radial diffusivity in the most anterior CC region than those in the AFE ≥12 group. This is the first study to find a relationship between AFE to RHI and later-life CC microstructure. These results suggest that incurring RHI during critical periods of CC development may disrupt neurodevelopmental processes, including myelination, resulting in altered CC microstructure.

External foam layers to football helmets reduce head impact severity.

PubMed

Nakatsuka, Austin S; Yamamoto, Loren G

2014-08-01

Current American football helmet design has a rigid exterior with a padded interior. Softening the hard external layer of the helmet may reduce the impact potential of the helmet, providing extra head protection and reducing its use as an offensive device. The objective of this study is to measure the impact reduction potential provided by external foam. We obtained a football helmet with built-in accelerometer-based sensors, placed it on a boxing mannequin and struck it with a weighted swinging pendulum helmet to mimic the forces sustained during a helmet-to-helmet strike. We then applied layers of 1.3 cm thick polyolefin foam to the exterior surface of the helmets and repeated the process. All impact severity measures were significantly reduced with the application of the external foam. These results support the hypothesis that adding a soft exterior layer reduces the force of impact which may be applicable to the football field. Redesigning football helmets could reduce the injury potential of the sport.

Consuming 375-500 ml of water 30 min before a meal has been shown to reduce energy intake in older, but not younger adults. This study investigated the effects of ingesting a water preload immediately pre-meal (<1 min before eating) on within-meal ad libitum energy intake in non-obese young males. Fourteen healthy males [mean (SD) age 27 (3) years, height 1.83 (0.05) m, body weight 80.47 (9.89) kg, body fat 17.5 (4.0) %, body mass index 24.0 (2.5) kg/m(2)] completed a familiarisation trial and two experimental trials in randomised counterbalanced order. Subjects arrived at the laboratory overnight fasted and consumed an ad libitum porridge breakfast. Immediately prior to the meal, subjects consumed either a 568 ml (1 pint) water preload (preload trial) or no preload (control trial). Visual analogue scale questionnaires to assess hunger, fullness and satisfaction were completed before and after the meal in both trials, as well as after the water preload. Ad libitum energy intake was greater (P < 0.001) during control [2551 (562) kJ] than preload [1967 (454) kJ]. Ad libitum water intake was also greater (P < 0.001) during control [318 (226-975) ml] than preload [116 (0-581) ml]. The water preload increased fullness and satisfaction and decreased hunger compared to pre-trial (P < 0.001) and the control trial (P < 0.001). This study demonstrates that consumption of a 568 ml water preload immediately before a meal reduces energy intake in non-obese young males. This might therefore be an effective strategy to suppress energy intake in this population and possibly assist with weight management.

Sport is highly relevant in the life of boys and young men. It is not only one of the most common and important leisure activities, but also helps male self-assurance through physical conflicts and competitions as well as through physical proximity and social involvement. At the same time, sport is an ambivalent area that preserves health, but can also be dangerous to it. By considering the development of male identity, the specific possibilities of sport, as well as an overview of the health situation of boys, this article develops starting points for lifestyle-oriented health promotion of boys and young men in the area of exercise, games and sport. In sports, physical practices are learned that can have long-term effects as somatic cultures on health behavior. The work with boys in sports can be health-promoting if opportunities and risks are reflected upon and considered in the didactic planning and execution.

Body mass index is associated with lumbar disc degeneration in young Finnish males: subsample of Northern Finland birth cohort study 1986

PubMed Central

2013-01-01

Background The role of environmental factors in lumbar intervertebral disc degeneration (DD) in young adults is largely unknown. Therefore, we investigated whether body mass index (BMI), smoking, and physical activity are associated with lumbar DD among young adults. Methods The Oulu Back Study (OBS) is a subpopulation of the 1986 Northern Finland Birth Cohort (NFBC 1986) and it originally included 2,969 children. The OBS subjects received a postal questionnaire, and those who responded (N = 1,987) were invited to the physical examination. The participants (N = 874) were invited to lumbar MRI study. A total of 558 young adults (325 females and 233 males) underwent MRI that used a 1.5-T scanner at the mean age of 21. Each lumbar intervertebral disc was graded as normal (0), mildly (1), moderately (2), or severely (3) degenerated. We calculated a sum score of the lumbar DD, and analyzed the associations between environmental risk factors (smoking, physical activity and weight-related factors assessed at 16 and 19 years) and DD using ordinal logistic regression, the results being expressed as cumulative odds ratios (COR). All analyses were stratified by gender. Results Of the 558 subjects, 256 (46%) had no DD, 117 (21%) had sum score of one, 93 (17%) sum score of two, and 92 (17%) sum score of three or higher. In the multivariate ordinal logistic regression model, BMI at 16 years (highest vs. lowest quartile) was associated with DD sum score among males (COR 2.35; 95% CI 1.19-4.65) but not among females (COR 1.29; 95% CI 0.72-2.32). Smoking of at least four pack-years was associated with DD among males, but not among females (COR 2.41; 95% CI 0.99-5.86 and 1.59; 95% 0.67-3.76, respectively). Self-reported physical activity was not associated with DD. Conclusions High BMI at 16 years was associated with lumbar DD at 21 years among young males but not among females. High pack-years of smoking showed a comparable association in males, while physical activity had

This study is the first empirical investigation that has explored levels of athletic identity in elite-level English professional football. The importance of understanding athletes' psychological well-being within professional sport has been well documented. This is especially important within the professional football industry, given the high attrition rate (Anderson, G., & Miller, R. M. (2011). The academy system in English professional football: Business value or following the herd? University of Liverpool, Management School Research Paper Series. Retrieved from http://www.liv.ac.uk/managementschool/research/working%20papers/wp201143.pdf ) and distinct occupational practices (Roderick, M. (2006). The work of professional football. A labour of love? London: Routledge). A total of 168 elite youth footballers from the English professional football leagues completed the Athletic Identity Measurement Scale (AIMS). Multilevel modelling was used to examine the effect of playing level, living arrangements and year of apprentice on the total AIMS score and its subscales (i.e., social identity, exclusivity and negative affectivity). Football club explained 30% of the variance in exclusivity among players (P = .022). Mean social identity was significantly higher for those players in the first year of their apprenticeship compared to the second year (P = .025). All other effects were not statistically significant (P > .05). The novel and unique findings have practical implications in the design and implementation of career support strategies with respect to social identity. This may facilitate the maintenance of motivation over a 2-year apprenticeship and positively impact on performance levels within the professional football environment.

The beliefs which motivate young male and female drivers to speed: a comparison of low and high intenders.

2012-03-01

In Australia, young drivers aged 17-24 years, and particularly males, have the highest risk of being involved in a fatal crash. Investigation of young drivers' beliefs allows for a greater understanding of their involvement in risky behaviours, such as speeding, as beliefs are associated with intentions, the antecedent to behaviour. The theory of planned behaviour (TPB) was used to conceptualise beliefs using a scenario based questionnaire distributed to licenced drivers (N=398). The questionnaire measured individual's beliefs and intentions to speed in a particular situation. Consistent with a TPB-based approach, the beliefs of those with low intentions to speed ('low intenders') were compared with the beliefs of those with high intentions ('high intenders') with such comparisons conducted separately for males and females. Overall, significant differences in the beliefs held by low and high intenders and for both females and males were found. Specifically, for females, it was found that high intenders were significantly more likely to perceive advantages of speeding, less likely to perceive disadvantages, and more likely to be encouraged to speed on familiar and inappropriately signed roads than female low intenders. Females, however, did not differ in their perceptions of support from friends, with all females reporting some level of disapproval from most friends and all females (i.e., low and high intenders) reporting approval to speed from their male friends. The results for males revealed that high intenders were significantly more likely to speed on familiar and inappropriately signed roads as well as having greater perceptions of support from all friends, except from those friends with whom they worked. Low and high intending males did not differ in their perceptions of the advantages and disadvantages of speeding, with the exception of feelings of excitement whereby high intenders reported speeding to be more exciting than low intenders. The findings are

2017-05-08

Alcohol-related problems at professional sporting events are of increasing concern and alarming reports are often reported in international media. Although alcohol consumption increases the risk for interpersonal violence, it is viewed as a focal element of large football events. Sweden has a long tradition of high public support for strict alcohol-control policies. However, little is known about public opinions on alcohol intoxication and the support for interventions to decrease intoxication at football events. The current study explored the public opinion towards alcohol use, intoxication and alcohol policies at professional football matches in Sweden. A cross-sectional design was utilized and a random general population sample of 3503 adult Swedish residents was asked to participate in a web survey during 2016 (response rate 68%). In total, 26% of the respondents supported alcohol sales at football events. Over 90% reported that obviously intoxicated spectators should be denied entrance or evicted from arenas. The support for regulations limiting alcohol availability varied with background factors such as gender, alcohol use and frequency of football event attendance. There is a strong public consensus for strategies and policies to reduce alcohol sales and intoxication levels at football matches. This public support has implications for our preventive efforts and will facilitate the implementation of strategies and policy changes.

Alcohol use and alcohol-related problems, including accidents, vandalism and violence, at sporting events are of increased concern in Sweden and other countries. The relationship between alcohol use and violence has been established and can be explained by the level of intoxication. Given the occurrence of alcohol use and alcohol-related problems at sporting events, research has assessed intoxication levels measured through biological sampling among spectators. This cross-sectional study aimed to assess the level of alcohol intoxication among spectators at football matches in the Swedish Premier Football League. Spectators were randomly selected and invited to participate in the study. Alcohol intoxication was measured with a breath analyser for Blood Alcohol Concentration levels, and data on gender, age, and recent alcohol use were gathered through a face-to-face interview. Blood Alcohol Concentration samples from 4420 spectators were collected. Almost half (46.8%) had a positive Blood Alcohol Concentration level, with a mean value of 0.063%, while 8.9% had a Blood Alcohol Concentration level ≥ 0.1%, with a mean value of 0.135%. Factors that predicted a higher Blood Alcohol Concentration level included male gender (p = 0.005), lower age (p < 0.001), attending a local derby (p < 0.001), alcohol use prior to having entered the arena (p < 0.001), attending a weekend match (p < 0.001), and being a spectator at supporter sections (p < 0.001). About half of all spectators at football matches in the Swedish Premier Football League drink alcohol in conjunction with the match. Approximately one tenth have a high level of alcohol intoxication.
