Respiratory responses to exercise in Sport

The respiratory system supports two important functions: to make oxygen (O2) available to the tissues of body and to eliminate carbon dioxide (CO2) from the tissues of the body. Breathing and exercise have always been closely linked in athletic training and any physical effort is quite evidently dependent on an efficient pulmonary ventilation. Exercise and a physically active lifestyle bring well-documented benefits either to athletes 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 presently considered to be caused by the frequently repeated increased ventilation occurring during training and competitions. Due to regular exercises, all athletes tend to have an increase in pulmonary capacity when compared to non-exercising individuals. Intensity and severity of sports engaged in by the athletes probably determines the extent of strengthening of the inspiratory muscles with a resultant increase in the pulmonary functions. 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 on respiratory system his training could improve athletic performance.
