人寿命的长短,在一定程度上是取决于心脏功能的强弱,取决于肺活量的高低(胸腔壁的扩张与收缩的宽舒程度)。爱运动的人心脏功能就强,肺活量就高,就能把身体的老化现象降低到最低程度。反之,心跳快的人由于心脏功能弱,排血量相对减少,老化程度就快。人如果久坐而不注意活动,可能引 The length of a person’s life, to a degree, depends on the strength of the heart, depending on the level of vital capacity (the extent of widening and contraction of the chest wall).
