肺活量常常是运动医学专家预测运动员运动潜能大小的根据。在做最大深吸气后再做最大呼气时呼出的气量,被称为“肺活量”。国外医学专家研究发现,肺活量可以作为衡量老年人健康与否及预测其寿命长短的重要指标。 现代医学揭示,人到三十五周岁左右时,肺活量开始逐渐下降。肺活量的减少意味着机体摄氧量的减少。健康人的肺每天可为身体的各个细胞提供总量达800升的氧气。人到老年后,由于肺活量的减少,动脉血氧的饱和度比青年人低5％～10％。美国波士顿大学医
Vital capacity is often the basis for sports medicine experts to predict the athletic potential of athletes. The amount of gas expired when doing maximum exhalation after doing maximum deep inspiration is referred to as “vital capacity.” Foreign medical experts found that vital capacity can be used as a measure of the health of the elderly or predict their life expectancy an important indicator. Modern medicine reveals that when people reach around the age of 35, their vital capacity begins to decline gradually. Reduction in vital capacity means a reduction in oxygen uptake in the body. Healthy human lungs can provide up to 800 liters of oxygen to all cells of the body daily. When people reach old age, arterial oxygen saturation is 5% -10% lower than that of young people due to the reduction of vital capacity. Boston University Medical
