本文拟对有关中、长跑的两个问题进行分析研究。第一个问题是:疲劳是怎样影响赛跑技术的?大家知道,用次极限强度进行标准负荷到极限时,其效率在疲劳状态下有所下降的原因是由于氧的需要量增加,而摄氧量下降和出现明显缺氧的结果。在这种情况下由于糖酵解过程不充分而造成严重的能量供 This article intends to analyze and study two issues concerning middle and long distance running. The first question is: How does fatigue affect racing technology? As you know, the reason for the decrease in efficiency when fatigue occurs with sub-ultimate strength is due to the increased oxygen requirement and the oxygen uptake The amount of decline and the apparent result of hypoxia. In this case due to inadequate glycolysis caused serious energy supply
