Reduction of lung elasticity due to training and expiratory flow limitation during exercise in competitive female rowers

摘要: Lung elasticity and lung volumes at rest were measured in 22 female rowers, 14 women who just started with rowing, 21 cyclists, 9 male rowers. The rowers had a higher specific static dynamic compliance (P less than 0.01) lower recoil pressure functional residual capacity 0.05) as compared to the other three groups. According their age, height, fat-free mass, normal vital capacity. volume, capacity, fast expiratory volume 1 s also normal. During an increased load test till exhaustion on bicycle ergometer, transpulmonary flow measured. While was not markedly groups, did increase linearly decreasing most of In there linear relation between pressure. elastic caused flow-limiting be reached level. difference showed that physical stress lungs during rowing is alike men. We assume typical physique requires extra fixation trunk pull phase stroke, which could lead loss
