Thoraco-abdominal asynchrony is often observed in many respiratory disorders and/or respiratory muscle dysfunctions and clinically assessed as a sign of respiratory distress and increased work of breathing. This review describes the assessment of thoraco-abdominal asynchrony by respiratory inductance plethysmography. Visual inspection ...

BackgroundIn patients with chronic obstructive pulmonary disease, a restriction on maximum ventilatory capacity contributes to exercise limitation. It has been demonstrated that the diaphragm in COPD is relatively protected from fatigue during exercise. Because of expiratory flow limitation the abdominal muscles are activated early ...

The authors measured respiratory muscle recruitment and ventilation ({dot V}{sub E}) during CO{sub 2} rebreathing before and after diaphragmatic fatigue in normal subjects. Muscle activity was assessed by measuring pleural, abdominal, and transdiaphragmatic pressures (Ppl, Pab, and Pdi, resp). The results showed ...

BackgroundGreater diaphragm fatigue has been reported after hypoxic versus normoxic exercise, but whether this is due to increased ventilation and therefore work of breathing or reduced blood oxygenation per se remains unclear. Hence, we assessed the effect of different blood oxygenation level on isolated hyperpnoea-induced inspiratory and expiratory ...

Skeletal muscle cramps are commonly encountered in marathon runners by medical staff. However, the aetiology, and therefore management, of this condition is not well understood. Exercise-associated muscle cramping (EAMC) is defined as an involuntary, painful contraction of skeletal muscle during or immediately after exercise. In early ...
