  1. Assessment of a Microsoft Kinect-based 3D scanning system for taking body segment girth measurements: a comparison to ISAK and ISO standards.


    Clarkson, Sean; Wheat, Jon; Heller, Ben; Choppin, Simon


    Use of anthropometric data to infer sporting performance is increasing in popularity, particularly within elite sport programmes. Measurement typically follows standards set by the International Society for the Advancement of Kinanthropometry (ISAK). However, such techniques are time consuming, which reduces their practicality. Schranz et al. recently suggested 3D body scanners could replace current measurement techniques; however, current systems are costly. Recent interest in natural user interaction has led to a range of low-cost depth cameras capable of producing 3D body scans, from which anthropometrics can be calculated. A scanning system comprising 4 depth cameras was used to scan 4 cylinders, representative of the body segments. Girth measurements were calculated from the 3D scans and compared to gold standard measurements. Requirements of a Level 1 ISAK practitioner were met in all 4 cylinders, and ISO standards for scan-derived girth measurements were met in the 2 larger cylinders only. A fixed measurement bias was identified that could be corrected with a simple offset factor. Further work is required to determine comparable performance across a wider range of measurements performed upon living participants. Nevertheless, findings of the study suggest such a system offers many advantages over current techniques, having a range of potential applications.

  3. [The virtuous doctor in cinema: the final examination].


    Figueroa, Gustavo


    The virtuous doctor has subscribed an oath and by subscribing to this solemn promise, he is committed to live in accordance with the purposes, obligations and virtues established in the medical profession. Cinematic art has shown only a superficial interest in complex aspects of medical profession. An exception is Ingmar Bergman's film "Wild Strawberries", where Professor Isak Borg, a widowed 76-year-old physician, is to be awarded the Doctor Jubilaris degree, 50 years after he received his doctorate at Lund University. During the trip, Isak is forced by a nightmare to reevaluate his professional life as not being a virtuous doctor.

    A strong link exists between low aerobic exercise capacity and complex metabolic diseases. To probe this linkage, we utilized rat models of low and high intrinsic aerobic endurance running capacity that differ also in the risk for metabolic syndrome. We investigated in skeletal muscle gene-phenotype relationships that connect aerobic endurance capacity with metabolic disease risk factors. The study compared 12 high capacity runners (HCRs) and 12 low capacity runners (LCRs) from generation 18 of selection that differed by 615% for maximal treadmill endurance running capacity. On average, LCRs were heavier and had increased blood glucose, insulin, and triglycerides compared with HCRs. HCRs were higher for resting metabolic rate, voluntary activity, serum high density lipoproteins, muscle capillarity, and mitochondrial area. Bioinformatic analysis of skeletal muscle gene expression data revealed that many genes up-regulated in HCRs were related to oxidative energy metabolism. Seven mean mRNA expression centroids, including oxidative phosphorylation and fatty acid metabolism, correlated significantly with several exercise capacity and disease risk phenotypes. These expression-phenotype correlations, together with diminished skeletal muscle capillarity and mitochondrial area in LCR rats, support the general hypothesis that an inherited intrinsic aerobic capacity can underlie disease risks.—Kivelä, R., Silvennoinen, M., Lehti, M., Rinnankoski-Tuikka, R., Purhonen, T., Ketola, T., Pullinen, K., Vuento, M., Mutanen, N., Sartor, M.

  8. Protocol variations in arm position influence the magnitude of waist girth.


    Lennie, Susan C; Amofa-Diatuo, Tracy; Nevill, Alan; Stewart, Arthur D


    Waist girth is recognised as a better predictor of obesity, particularly abdominal obesity, compared to other measures. Although several protocols for waist girth exist, arm position is either ignored, or not specified in unambiguous terms. Therefore, the purpose of this study was to determine if arm position influenced anthropometric waist girth measurement. Waist girth was measured in 92 adults (19 males, 73 females) with arms relaxed, abducted, horizontal, folded across the chest (three variations) and raised vertically. Duplicate measures, in all positions, were recorded by a single International Society for the Advancement of Kinanthropometry (ISAK)-trained technician to a precision of 0.2% technical error of measurement (TEM). Arm position had a significant effect (P < 0.001) on waist girth. Male participants had greater waist girth than females (P < 0.001) and the waist girth differences across the varying arm positions exhibited a significant position-by-gender interaction (P < 0.001). The arm position-by-body mass index (BMI) category interaction was also significant (P = 0.016) with greater differences observed at higher BMI. These findings suggest caution in comparing results of different studies where arm position is not specified and indicate that the arm position corresponding to the ISAK protocol has the lowest error and is therefore recommended.

Resultados: nos encontramos con deportistas de talla baja, en los que destacan valores inferiores a lo normal en los pliegues cutáneos subescapular, supraespinal, tricipital y bicipital, un porcentaje de masa muscular (45,27 ± 3,29%), de masa grasa (10,22 ± 2,92%) y de masa ósea (16,65 ± 1,34%) y un somatotipo en el que predomina la mesomorfia. Discusión: los triatletas y corredores presentan más baja talla que los ciclistas y nadadores. Los triatletas y ciclistas muestran un peso similar, siendo menor que el de los nadadores de fondo y mayor que el de los corredores de 10 km. Los pliegues cutáneos cresta ilíaca, abdominal y muslo frontal de los ciclistas son inferiores al de los triatletas. El porcentaje de masa grasa de triatletas corredores y nadadores son similares; sin embargo, el de la masa muscular de los triatletas suele ser inferior al de los ciclistas pero similar a las demás modalidades. El somatotipo del triatleta se asemeja al del ciclista (mesomorfo). El del corredor es mesomorfo-ectomorfo y el del nadador puede

  10. Anthropometric dimensions of male powerlifters of varying body mass.


    Keogh, Justin W L; Hume, Patria A; Pearson, Simon N; Mellow, Peter


    In this study, we examined the anthropometric dimensions of powerlifters across various body mass (competitive bodyweight) categories. Fifty-four male Oceania competitive powerlifters (9 lightweight, 30 middleweight, and 15 heavyweight) were recruited from one international and two national powerlifting competitions held in New Zealand. Powerlifters were assessed for 37 anthropometric dimensions by ISAK (International Society for the Advancement of Kinanthropometry) level II and III accredited anthropometrists. The powerlifters were highly mesomorphic and had large girths and bony breadths, both in absolute units and when expressed as Z(p)-scores compared through the Phantom (Ross & Wilson, 1974). These anthropometric characteristics were more pronounced in heavyweights, who were significantly heavier, had greater muscle and fat mass, were more endo-mesomorphic, and had larger girths and bony breadths than the lighter lifters. Although middleweight and heavyweight lifters typically had longer segment lengths than the lightweights, all three groups had similar Zp-scores for the segment lengths, indicating similar segment length proportions. While population comparisons would be required to identify any connection between specific anthropometric dimensions that confer a competitive advantage to the expression of maximal strength, anthropometric profiling may prove useful for talent identification and for the assessment of training progression in powerlifting.

  11. To what extent does sexual dimorphism exist in competitive powerlifters?


    Keogh, Justin W L; Hume, Patria A; Pearson, Simon N; Mellow, Peter


    We examined sexual dimorphism in the anthropometry of 68 Australasian and Pacific powerlifters (14 females, 54 males) who were competing in one of two national or international powerlifting competitions held in New Zealand. All powerlifters were assessed for 37 anthropometric dimensions by ISAK (International Society for the Advancement of Kinanthropometry) Level II and III accredited anthropometrists. While the powerlifters were highly mesomorphic and possessed large girths and bone breadths, both in absolute terms and when expressed as Z(p)-scores compared through the Phantom (Ross & Wilson, 1974), these characteristics were often more pronounced in male than female lifters. No significant inter-gender differences in any of the measures of adiposity were observed. When normalized through the Phantom, the female and male powerlifters had relatively similar segment lengths and bone breadths, indicating that regardless of gender, competitive powerlifters possess comparable skeletal proportions. These results indicate that although competitive powerlifters exhibit sexual dimorphism for many absolute anthropometric measures, little dimorphism is found for measures of adiposity and for proportional segment lengths and bone breadths. These results further support the importance of anthropometric profiling for powerlifting, and suggest that successful male and female powerlifters will possess similar proportional characteristics.

  12. [Anthropometric characteristics and skeletal maturity of male Venezuelan swimmers].


    Salazar-Lioggiodice, Marinés; Arroyo, Esteban; Pérez, Betty


    Knowledge of the morph-physiological conditions of young athletes, it of the utmost importance for planning better trainning programs and to identify those characteristics that lead to a better performance. This paper aims to classify a group of 114 male Venezuelan swimmers of the Miranda State contingent, aged between 7.00 and 18.99 years old, based on their anthropometric characteristics and skeletal maturity. For this purpose multivariate methods: Analysis of Principal Components (APC) and the Automatic Classification were employed. Anthropometric variables followed the International Society for the Advancement of Kinantropometry (ISAK) guidelines. Skeletal maturity and five indexes of body composition: brachial, crural, cormic and acromiale-iliac indexes, were additionally considered in the analysis. Three groups emerged very well defined and homogenous within and between groups. The first group identifies the younger swimmers with the smallest values in corporal dimensions. The second group comprises those swimmers characterized fundamentally by a greater development of the bicrestal diameter. In the third group, greater values of the anthropometrical variables were found, that shaped the typical profile of the swimmers, mainly characterized by a trapezoidal trunk. Most of the swimmers are advanced in skeletal age related to chronological age. This clustering of the swimmers permits a suitable way to identify the bio-morphological characteristics of the athletes.

    The aim of the study was to characterize the anthropometric profile and somatotype of a sample of 50 players table tennis competitive with an average age 21.6 (± 3.1) years belonging to the Chilean team and institutions of higher education in the region of Valparaiso. The evaluation was conducted under the protocol marking the International Society for the Advancement of Kinanthropometry (ISAK) for the measurement procedure 25 restricted profile variables described by Drinkwater, Norton and Olds. Order to determine the body composition, fat, muscle, bone, skin and tissue residual was considered, using the equations proposed by Kerr. The body shape is characterized through somatotype method proposed by Carter. The sample was divided into 4 groups; Chilean Selection, Traditional Private Universities, State Universities and Private Universities Traditional Nontraditional. Regarding body composition; the Chilean team has the highest values of muscle tissue (45.6 ± 1.7%) and the lowest values of adipose tissue (25.2 ± 1.8%), also presenting lesser value in the Σ 6 skinfolds (mm) . The results showed no significant differences between groups in the aforementioned variables. In general somatotype compared by analyzing SANOVA no significant differences between groups (p = 0.409) was observed. The results show a biotype with such a characterization of endo-mesomorph with average values (4,1-4,9-1,8). This study provides updated data biotypological reference for this sport that can be used for decision-making.

    Objective: To identify the contribution of anthropometric variables to predict the maturational stage in young males. Methods: Cross-sectional study that enrolled 190 male subjects aged between eight and 18 years, randomly selected from public and private schools in Natal, Northeast Brazil. Thirtytwo anthropometric variables were measured following the recommendations of the International Society for the Advancement of Kineanthropometry (ISAK). The assessment of sexual maturation was based on the observation of two experienced experts, who identified the pubertal development according to Tanner guidelines (1962). Results: The anthropometric variables showed a significant increase of their values during the advancement of pubertal development (p<0.05). The following variables showed the best value for prediction of maturational groups: sitting height, femoral biepicondylar diameter, forearm girth, triceps skinfold, tibiale laterale and acromiale-radiale bonelenghts. These variables were able to estimate the pubertal stages in 76.3% of the sujects. Conclusion: The anthropometric characteristics showed significant differences between the moments of maturational stages, being found, representatively, seven variables that best predict the stages of sexual maturation.

    In 1996, a mixed Ellisras longitudinal study (ELS) was initiated to assess the stability of somatotypes in 408 girls who comprised 99 pre-school and 309 primary school children in Ellisras rural area in the Northern Province of South Africa. The children's somatotype was assessed using the Heath-Carter anthropometric method. Anthropometric dimensions were taken according to the protocol of the International Society for the Advancement of Kinanthropometry (ISAK). The most stable pre-school and primary school girl had migratory distances (MDs) of 2.6 and 3.4, respectively, while the least stable pre-school and primary school girl had MDs of 17.9 and 24.4, respectively. The mean somatotype of the pre-school children was mesomorph-ectomorph throughout the complete age range, while the mean somatotype of primary school girls was mesomorph-ectomorph for all the age groups except for the 9.5 years group at which it was in the balanced ectomorph. The inter-age partial correlations for endomorphy and ectomorphy were high and significant, but insignificant with regard to mesomorphy.

  16. New percentage body fat prediction equations for Japanese males.


    Kagawa, Masaharu; Kerr, Deborah; Binns, Colin W


    Anthropometry is simple, cheap, portable and non-invasive method for the assessment of body composition. While the Nagamine and Suzuki body density prediction equation has been frequently used to estimate %BF of Japanese, the equation was developed more than 40 years ago and its applicability to the current Japanese population has not been studied. This study aimed to compare %BF results estimated from anthropometry and dual energy X-ray absorptiometry (DXA) in order to examine applicability of the Nagamine and Suzuki equation. Body composition of 45 Japanese males (age: 24.3+/-5.5 years, stature: 171.6+/-5.8 cm, body mass: 62.6+/-7.1 kg, %BF: 15.7+/-5.6%) were assessed using whole-body DXA (Hologic QDR-2000) scan and anthropometry using the protocol of the International Society for the Advancement of Kinanthropometry (ISAK). From anthropometric measurements %BF was calculated using the Nagamine and Suzuki equation. The results showed that the Nagamine and Suzuki equation significantly (p<0.05) underestimated %BF of Japanese males compared to the DXA results. There was a trend towards greater underestimation as the estimated %BF values using DXA increased. New %BF prediction equations were proposed from the DXA and anthropometry results. Application of the proposed equations may assist in more accurate assessment of body fatness in Japanese males living today.

  17. Can absolute and proportional anthropometric characteristics distinguish stronger and weaker powerlifters?


    Keogh, Justin W L; Hume, Patria A; Pearson, Simon N; Mellow, Peter J


    This study sought to compare the anthropometric profiles of 17 weaker and 17 stronger Australasian and Pacific powerlifters who had competed in a regional-, national-, or international-level powerlifting competition in New Zealand. Stronger lifters were defined as those having a Wilks score greater than 410, whereas those in the weaker group had a Wilks score less than 370. Each powerlifter was assessed for 37 anthropometric dimensions by International Society for the Advancement of Kinanthropometry (ISAK) level II and III accredited anthropometrists. Because all powerlifters were highly mesomorphic and possessed large girths and bone breadths, both in absolute terms and when expressed as Phantom-Z scores compared through the Phantom, relatively few significant anthropometric differences were observed. However, stronger lifters had significantly greater muscle mass and larger muscular girths in absolute terms as well as greater Brugsch Index (chest girth/height) and "Phantom"-normalized muscle mass, upper arm, chest, and forearm girths. In terms of the segment lengths and bone breadths, the only significant difference was that stronger lifters had a significantly shorter lower leg than weaker lifters. Because the majority of the significant differences were for muscle mass and muscular girths, it would appear likely that these differences contributed to the stronger lifters' superior performance. Powerlifters may therefore need to devote some of their training to the development of greater levels of muscular hypertrophy if they wish to continue to improve their performance. To better understand the anthropometric determinants of muscular strength, future research should recruit larger samples (particularly of elite lifters) and follow these subjects prospectively.

  18. Anthropometry and somatotypes of competitive DanceSport participants: a comparison of three different styles.


    Liiv, H; Wyon, M; Jürimäe, T; Purge, P; Saar, M; Mäestu, J; Jürimäe, J


    Anthropometry in dance and aesthetic sports has been shown to play an important role in selection and performance criteria. The aim of the present study was to examine variations in somatotype and anthropometry in three different competitive dance styles: DanceSport Standard, Latin American and Ten Dance. Anthropometry and somatotype data were collected from thirty couples competing in Standard (n=24 individuals), Latin American (n=14) and Ten Dance (n=22) styles. A single tester (ISAK Level 1) carried out all anthropometric measurements using the Heath-Carter protocol and somatotypes were calculated using the Heath-Carter's decimal equations. Results indicated that the mean somatotype for the male dancers was 2.4-3.9-3.2, whilst for females it was 2.7-2.7-3.5. Factorial analysis reported Standard dancers scored significantly higher for ectomorphy, sitting height and arm span than Latin dancers (p<0.05). Correlation analysis with the Standard dancer's International Ranking highlighted moderate positive correlation with mesomorphy (r=0.434, p<0.05) and negative correlation with ectomorphy (r=-0.546, p<0.001). The findings of this study show that somatotypes differ among DanceSport participants by dance style. Compared with other aesthetic sports, male and female dancers were less mesomorphic and more ectomorphic. Standard dancers tend to be more ectomorphic with greater height, longer arm span and greater sitting height compared with Latin American dancers. Although Standard dancers were ectomorphic, those dancers who had higher mesomorphic ranking had higher places in the dancers' international ranking.

    Dave, Bhargav; Dave, Asmi; Kotecha, Nilesh; Oates, Myrtle


    Introduction The triathlon involves a combination of three separate disciplines-swimming, cycling and running. To date, very few studies have been conducted on the anthropometric characteristics of the New Zealand junior elite triathletes. The aim of this study was to determine the correlation between physical traits of calf girth or sum of eight skinfolds (anthropometry) and running or cycling performances in the triathlon event. Methods Eleven junior elite triathletes (6 females, 5 males; (Av. age: 17) who were selected for the New Zealand national squad, were examined in this cross-sectional study. All athletes were measured for the complete anthropometric profile, as per the International Society for Advancement of Kinanthropometry (ISAK) guidelines. It was then correlated with the cycling and running performances using interclass correlation (ICC) with 90% confidence interval (CI) limits. Results A non-significant positive correlation observed between eight skinfolds tests on running performance (ICC: 0.10; 90% CI: −0.68–0.77; p>0.05) and biking performance (ICC: 0.15; 90% CI: −0.65–0.79; p>0.05), suggested athletes with greater body fat may render a better athletic performance. Conversely, a significant negative correlation was observed between calf girth and running performance (ICC:−0.66; 90% CI: −0.94 – −0.12; p<0.05) and a non-significant negative correlation was observed between calf girth and cycling performance (ICC:−0.94; 90% CI: −0.97– 0.68; p>0.05). Conclusion Anthropometric data can help in predicting an ideal body profile. This research indicates the similarities and differences of the New Zealand junior profile and the world junior profile.

    Introduction Vertical Jump (VJ) is a good measure of athletic performance and occupational activities. Earlier studies reported conflicting results on anthropometric influence. Aim To evaluate the relationship between anthropometric characteristics and VJ in national level hockey and cycling players. Materials and Methods Fifty four (32 males) national level hockey and cycling players of 11-21 years were the volunteers. Following standard protocols, these variables were measured: VJ, Weight (WT), Height (HT), Trochanterion-Height (TH), Sum of Skinfold Thickness (SSF), Lengths [Acromiale-Stylion (AS) and Midstylion-Dactylion (SD)], Breadths [Biacromial (AB), Biiliocristal (IB), Biepicondylar Humerus (HB) and Biepicondylar Femur (FB)], Girths [Relaxed Arm (AG), Mid Thigh (TG) and Calf (CG)], Lower Back and Hamstring Flexibility (SR), Grip [Left Hand Grip (LHG) and Right Hand Grip (RHG)] and Back Strength (BS). International Society for the Advancement of Kinanthropometry (ISAK) procedures were followed for anthropometric variables measurement. Unpaired-‘t’-test was used for comparison between genders. Pearson’s correlation and multiple regression analysis were used to evaluate correlates and predictors of VJ respectively. Results Males had significantly higher VJ, HT, SD, AB and BS; but lower SSF, AS and TG. VJ correlated positively with age, WT, HT, SD, TH, girths, SR and strength among males; but only with WT and LHG among females. After controlling gender, TH and LHG predicted VJ significantly with 69% of total variance. HT, SSF and BS; and LHG were the significant predictors among males and females respectively. Conclusion Anthropometric and physiological variables like TH, grip, HT, skinfold and BS had major influence on VJ. The result might help in training-monitoring and player’s selection.

    Objetivo: el objetivo de este estudio consiste en relacionar parámetros de composición corporal sobre el rendimiento en ciclistas recreacionales, utilizando la masa grasa (MG), la masa muscular total (MM) y apendicular de la extremidad inferior (MMEI) con la potencia aeróbica máxima (PAM). Material y métodos: se reclutaron 11 ciclistas (27,7 ± 4,5 años; 72,4 ± 12,4 kg; 173,2 ± 6,7 cm) hombres. Las medidas antropométricas fueron realizadas de acuerdo a los protocolos de la International Society for the Advancement of Kineanthropometry (ISAK), y las pruebas de PAM se llevaron a cabo siguiendo un protocolo en rampa, que comenzó con una carga inicial de 150 W y, posteriormente, con incrementos de 30 W a intervalos de un minuto hasta llegar al agotamiento. Resultados: existe dependencia entre las variables de MG y el VO2máx que se correlacionan de forma negativa y significativa (p < 0,05). Respecto a las variables MM y el VO2máx, correlacionan significativamente de forma negativa (p < 0,05). En la correlación de la MMEI con la PAM puede apreciarse una correlación positiva y muy significativa (p < 0,01), lo que indicó que los sujetos que tienen un mayor componente muscular en las extremidades inferiores (EEII) son capaces de generar una mayor potencia. Conclusiones: podemos concluir que de los resultados obtenidos, tanto la MG como la MM no son un buen referente como parámetro de rendimiento respecto a la VAM. La MMEI fue el único parámetro que reflejó una relación positiva como marcador de rendimiento en ciclistas recreacionales.

    Objective To investigate correlates of changes in waist-to-height ratio (WHtR) in primary school children in order to identify modifiable factors usable for prevention. Methods Outcome evaluation of a statewide health promotion program in Baden-Württemberg, Germany. Baseline (2010) and follow-up (2011) measurements provided data for the calculation of changes in WHtR. Further information on the health and living conditions of the children were assessed in parental questionnaires. Anthropometric measures were taken in 1733 (50.8% male) first and second grade children (age at baseline 7.1 ± 0.6 years) by staff trained according to ISAK-standards. Stepwise linear regression analysis was applied to identify variables with influence on changes in WHtR. Results According to the resulting regression model, changes in WHtR towards an increase were influenced by at least one parent being overweight/obese, at least one parent who smoked, low household income, higher age of the child and the skipping of breakfast. There was no clustering effect in schools observed. Conclusion A promising target for prevention of gain in WHtR in primary school children is to ensure the regularity of breakfast. Smoking cessation as well as dietary improvements would not only help children's health but also the health of their parents. The socioeconomic influence on the development of an unhealthy weight status has already been acknowledged and should be extensively targeted by all of society and policy makers. PMID:26844178

  3. [The effects of 16-weeks pilates mat program on anthropometric variables and body composition in active adult women after a short detraining period].


    Vaquero-Cristóbal, Raquel; Alacid, Fernando; Esparza-Ros, Francisco; Muyor, José M; López-Miñarro, Pedro Ángel


    Introducción: Estudios previos han analizado los efectos de la práctica de Pilates mat sobre las variables antropométricas y la composición corporal en poblaciones sedentarias. No existen estudios sobre los beneficios del Pilates en estas varibles tras un corto periodo de desentrenamiento. Objetivo: Determinar el efecto un programa de 16 semanas de Pilates mat sobre las variables antropométricas, la composición coporal y el somatotipo, en mujeres adultas con experiencia previa tras 3 semanas de desentrenamiento. Metodología: A veintiuna mujeres se les realizó una valoración antropométrica completa siguiendo las indicaciones de la ISAK antes y después de un programa de Pilates mat de 16 semanas (2 días a la semana, una hora por día). Todas las mujeres tenían una experiencia previa en la práctica de Pilates mat de entre 1 y 3 años y venían de un proceso de desentrenamiento de 3 semanas (vacaciones de Navidad). Resultados y discusión: Las mujeres mostraron una reducción significativa del peso corporal, el IMC, los pliegues cutáneos individuales del miembro superior (bíceps y tríceps) y el tronco (subescapular, cresta iliaca, supraespinal y abdominal), el sumatorio de 6 y 8 pliegues, la endomorfia y la masa grasa; y un aumento significativo de la masa muscular. El somatotipo medio se clasificó en meso-endomorfo para el pre- (4,91, 4,01, 1,47) y el post-test (4,68, 4,16, 1,69). Ocho mujeres cambiaron su clasificación del somatotipo tras el programa de intervención. Conclusiones: La práctica de Pilates mat durante 16 semanas provocó cambios asociados a una mejora del estado de salud en las variables antropométricas, sobre todo en los pliegues cutáneos que disminuyeron significativamente, la composición corporal (masa grasa y muscular, que disminuyeron y aumentaron, respectivamente) y el somatotipo (una reducción significativa del componente endomórfico) en mujeres con experiencia previa en la práctica de Pilates después de tres semanas

    Introducción y objetivo: La valoración del estado antropométrico y nutricional de la población universitaria es importante para detectar grupos de riesgo y realizar recomendaciones nutricionales. El objetivo fue analizar la composición corporal y el porcentaje de grasa en un grupo de estudiantes universitarios y evaluar su metabolismo basal para ver si había una correlación con la composición corporal. El estudio se llevó a cabo a través de diferentes métodos, para determinar si los resultados obtenidos son comparables. Sujetos y método: La muestra fueron 16 alumnos (4 hombres y 12 mujeres) de la Universidad de Valencia, 20- 33 años de edad. A todos se hizo el estudio de la composición corporal y a 6 de ellos se hizo también un estudio metabólico. Resultados: Se encontró que el 75% de los sujetos estudiados tienen un peso normal, el 12,5% tienen bajo peso y 12,5% tiene sobrepeso. El porcentaje de sujetos con grasa corporal superior a los valores normales son: 68,75% según BFMNU, el 25% a través del método ISAK y 7,69% según BIA. Conclusiones: Nuestro estudio mostró que los datos obtenidos a través de los diferentes métodos no son directamente comparables, ya que se basan en diferentes principios y supuestos. También se ha observado la importancia de considerar no sólo la masa grasa, si no toda la composición corporal para tener una visión completa del sujeto. Además, se ha podido notar que la calorimetría indirecta y las ecuaciones de predicción del metabolismo basal no son capaces de estimarlo correctamente. En cambio el método BFMNU es el que da más información y permite investigar a fondo el metabolismo.

    Introducción: casi no hay ninguna referencia sobre las características antropométricas, la composición corporal y el somatotipo de la mano de los jugadores de pelota vasca (pelotaris) en la literatura científica. Objetivos: el objetivo de esta investigación fue comparar la composición corporal de pelotaris profesionales y sub-23 para crear el perfil antropométrico de este deporte. Métodos: participaron diez pelotaris sub-23 y ocho pelotaris profesionales. Las medidas antropométricas fueron recogidas siguiendo el protocolo de la Sociedad Internacional de Promoción de Protocolo Cineantropometría (ISAK). La masa grasa (FM) se calculó utilizando la ecuación Yushasz modificada por Carter, y la masa muscular (MM) mediante la ecuación de Lee. Los componentes del somatotipo fueron estimados mediante la ecuación Carter y Heath. El nivel de hidratación de los pelotaris se midió con un analizador tetrapolar de impedancia bioeléctrica (BIA). Resultados: los pelotaris profesionales tienen significativamente menor FM (en % (p = 0,001); en kg (p = 0,025) y en los sumatorios de 4, 6 y 8 pliegues cutáneos (p = 0,001); mayor MM (p = 0,015) y un menor componente endomórfico (p < 0,001) que los pelotaris sub-23. Asimismo, los profesionales tienen una mayor cantidad de agua corporal (p = 0,001) y un diámetro mayor biestiloideo de muñeca (p = 0,014). Los pelotaris profesionales son un morfotipo caracterizado por una baja FM (8,9 ± 1,1%) y una intermedia MM (47 ± 1,7%), además de tener una altura de 183,0 ± 7,1 cm y un peso de 85,9 ± 7,6 kg. Conclusión: los principales resultados de este estudio mostraron que las características antropométricas no modificables por el entrenamiento (por ejemplo, altura, envergadura y diámetro de la muñeca) son componentes importantes para convertirse en un pelotari profesional. Por otra parte, las características relacionadas con el entrenamiento y la dieta han mostrado ser mejores en los pelotaris profesionales (menor FM

    Introducción: diversas investigaciones señalan una coherencia entre la falta de actividad física con menores niveles de movilidad articular en cadera y rodilla. Objetivo: determinar las diferencias en los rangos de movilidad articular de cadera y rodilla entre las distintas clasificaciones de somatotipo, en estudiantes de Pedagogía en Educación Física de la Universidad Autónoma de Chile, sede Temuco (EFUA). Material y método: la muestra incluyó 102 estudiantes de educación física (31,3% mujeres), se obtuvo el somatotipo a través del protocolo de la International Society for the Advancement of Kinanthropometry (ISAK), y los rangos de movilidad articular de cadera y rodilla (ROM) utilizando un goniómetro universal. Resultados: el somatotipo promedio para mujeres EFUA fue endomesomorfo (4,8 - 3,4 - 2) y para varones EFUA mesoendomorfo (3,5 - 5,7 - 2), mientras que la evaluación de ROM señala que el 50% de los estudiantes presentó valores de movilidad articular inferiores a lo normal. Además, las mujeres EFUA clasificadas como endomesomorfas manifiestan valores más bajos de ROM para la rotación medial de cadera derecha (45,5°±10,2°; P=0,0125; t=2,732) y rotación lateral de cadera izquierda (41,7°±10,3°; P=0.0256; t=2.402) al compararlas con las mujeres EFUA mesoendomorfas. Conclusión: existe relación entre el somatotipo y los ROM de cadera en las mujeres EFUA, quienes manifiestan resultados más favorables de movilidad articular a mayor masa muscular, sin encontrarse diferencias significativas en los varones EFUA. Es importante propiciar el desarrollo de ejercicios de movilidad articular en función de las necesidades específicas de cada sexo.

    Introducción: la aplicación de modelos de proporcionalidad, basados en proporciones ideales, tendría un gran impacto en el deporte de alto rendimiento, debido a que los mejores deportistas tienden a asemejarse antropométricamente. Objetivo: el objetivo de este estudio es comparar los métodos de proporcionalidad antropométrica: Phantom, Combinado y Escalable, en los campeones chilenos de fútbol masculino universitario de los años 2012 y 2013, ocupando como población de criterio a futbolistas profesionales sudamericanos, con el fin de encontrar el método de proporcionalidad más adecuado para poblaciones de deportistas. Metodología: se realizó la evaluación de 22 variables kineantropométricas, según el protocolo ISAK, a una muestra constituida por 13 jugadores pertenecientes a la selección masculina de fútbol de la Pontificia Universidad Católica de Valparaíso. Se obtuvieron los valores Z de cada variable antropométrica de los diferentes métodos, usando sus fórmulas respectivas. Se usó como población de criterio a los futbolistas profesionales sudamericanos. Resultados: se observó una tendencia semejante entre los tres métodos. Se encontraron diferencias significativas (p < 0,05) en los valores Z de los métodos Escalable y Combinado, respecto al método Phantom. No se encontraron diferencias significativas entre los resultados obtenidos por los métodos Combinado y Escalable, excepto en los perímetros radiocarpiano, cadera y muslo. Conclusión: se propone la utilización del método Escalable sobre el método Combinado y Phantom para realizar la comparación de valores Z en variables kineantropométricas en deportistas de la misma disciplina.

    Introducción: existen alteraciones frecuentes en la alimentación de la población infantil femenina, y especialmente en atletas de deportes estéticos por la presión ejercida para mantener un cuerpo.Objetivos: evaluar los aspectos nutricionales, antropométricos y la percepción del peso de niñas que realizan gimnasia rítmica frente a un grupo control.Métodos: estudio descriptivo comparativo. Se compararon 25 niñas gimnastas con 25 niñas no gimnastas (control). Se realizó una valoración antropométrica, mediante protocolo ISAK, y nutricional, mediante un registro dietético de siete días; así como una valoración cuantitativa y cualitativa de la ingesta alimentaria, mediante el software DIAL. Se rellenó un cuestionario de hábitos y sobre la percepción de su peso corporal.Resultados: los datos antropométricos no presentaron diferencias significativas entre ambos grupos, excepto en los pliegues cutáneos y el porcentaje de grasa, el cual era estadísticamente inferior en gimnastas. La ingesta energética (1.413 ± 283 Kcal/día) de las gimnastas era inferior a la recomendada por la Food and Nutrition Board de acuerdo a su edad. La distribución de los macronutrientes cumplía con los valores normales establecidos (10-30% proteínas, 45-65% hidratos, 20-35% grasas). El 32% de las gimnastas y el 36,4% de las niñas control consideraron que les gustaría pesar menos.Conclusión: teniendo en cuenta la intensa actividad de las gimnastas, sus requerimientos energéticos deberían ajustarse a ello, ya que esto contribuirá a su desarrollo y crecimiento y a una mejor ejecución del ejercicio. En la muestra estudiada, el consumo de alimentos de las gimnastas se aleja de una alimentación equilibrada. No se observaron comportamientos diferentes en la percepción del peso entre ambos grupos.
