积极的功(上坡跑)比消极的功(下坡跑)大约多消耗两倍。因为这种功耗关系,有的权威们认为教练员们用在斜面上跑去改善跑的速率。但是,当赛跑运动员进行上坡跑或下坡跑时,他的生物力学因素和关系发生了什么情况?教练员们是怎样理解在运动员上坡和下坡跑训练时他们生物力学变量的变化? 研究的目的是测定在3％斜坡向上跑和3％斜坡向下跑时生物力学变量的改变。步骤受测者是瑞士1978年国家队10名男性短跑预备队员和10名十项运动预备队员, Positive work (uphill running) consumes about twice as much as negative work (downhill running). Because of this power relationship, some authorities think the coaches ran on the ramp to improve the running speed. But what happens to his biomechanical factors and relationships when a runner runs uphill or downhill? How do coaches understand their biomechanical variables as they rise and downhill? The purpose of the study was to determine changes in biomechanical variables at 3% run-up and 3% run-down. Step The participants were Switzerland’s 1978 national team of 10 male sprint reserve team members and 10 of the 10 reserve members,
