摘要:The respiratory system supports two important functions: to make oxygen (O2) available to the tissues ofbody and to eliminate carbon dioxide (CO2) from the tissues of the body. Breathing and exercise have alwaysbeen closely linked in athletic training and any physical effort is quite evidently dependent on an efficientpulmonary ventilation. Exercise and a physically active lifestyle bring well-documented benefits either toathletes with a normal respiratory function and those with respiratory diseases, asthma in particular.Development of asthma and bronchial hyper responsiveness in the competing elite athlete is presentlyconsidered to be caused by the frequently repeated increased ventilation occurring during training andcompetitions. Due to regular exercises, all athletes tend to have an increase in pulmonary capacity whencompared to non-exercising individuals. Intensity and severity of sports engaged in by the athletes probablydetermines the extent of strengthening of the inspiratory muscles with a resultant increase in the pulmonaryfunctions. Today, elite athletes from various sports, including cycling, swimming, rowing and athletics,undertake specific training for the breathing muscles, hoping to improve their competitive results. However,the effectiveness of such training has often been questioned. The study observe the effect of exercise onrespiratory system his training could improve athletic performance.
