Exercise-induced Respiratory Muscle Fatigue and Athletic Ability of the Endurance Projects

Depending on the duration and intensity of the exercise,the physiologic factors that limit the performance of endurance exercise are complex and various.Intensive training can cause respiratory muscle fatigue.Exercise-induced respiratory muscle fatigue may play a pivotal role in determining exercise tolerance through both of its direct effect on muscle force output(peripheral fatigue) and its uneasy self-induction feedback on body strength which reduces the unite output power of working muscular movement(central fatigue).Thus,training the respiratory muscles may improve the performance of endurance exercise.
