中跑和长跑运动员各6名,短跑运动员4名进行渐增负荷运动和稳态运动。我们对三组受试者的无氧阈(AT)在无氧阈时的氧亏(AT—O_(2df))以及吸氧量的时程(T)进行了比较,并探讨了三个参数间的关系,其结果如下: 1、无氧阈时的吸氧量值以长跑运动员最高。其次为中跑运动员,短跑选手最低。除以公斤体重后以及用%Vo_(2max)表示时,其值的大小顺序亦是如此。2、长跑运动员单位体重的AT—O_(2df)与中跑运动员相同,二者均显著性地大于短跑运 6 runners and long distance runners each, and 4 sprinters performed progressive load exercise and steady exercise. We compared oxygen-deficient (AT) oxygen deficit (AT-O_ (2df)) and oxygen uptake time course (T) at three anaerobic thresholds in three groups of subjects and explored three parameters The results are as follows: 1, oxygen-free threshold when the amount of oxygen to runners the highest. Followed by middle runners, sprinters minimum. Divided by kilogram body weight and expressed as% Vo_ (2max), the order of magnitude is also the same. 2, long-distance runners weight AT-O_ (2df) and runners the same, both significantly greater than the short run
