 note = {application/pdf, How comes a beginning swimmer can not continue swimming. According to our studies about the analysis of the spirogram of his respiratory habit, he does not or can not enough expire, so inspiration becomes shallow and expire level goes up step by step. It invites him to Hypoventilation that means to decrease tidal volume and to increase breathing frequency and dead space too. We say that he has difficulties in breathing. We assert that explosive expiration is rational for quick inspiration on the physiological function and motor innervation. But, generally speaking, a poor swimmer can not enough to expire under water, therefore, it is better that beginning swimmer should be taught not only to inspire but also to expire explosively in air than to expire under water.},
