Isokinetic assessment of elite squash, tennis and track athletes confirms the accepted ratio of 60 to 80 per cent hamstring to quadriceps when testing at 90 deg-sec-1 for peak strength (torque). However, significant variations occur at higher test speeds up to 300 deg.sec-1 with the hamstrings becoming more prominent especially (p less than 0.001) in the nonpreferred (NP) leg. There was no significant difference between sports, and wide individual differences occurred. Analysis of (work.sec-1.kg-1 body weight) power showed a significantly higher work output (p less than 0.01) by track athletes than squash and tennis players, but, unlike hamstring/quadriceps ratio, no significant difference between preferred (P) and nonpreferred leg. The maximum power output was achieved around 220 to 250 deg.sec-1. Power between preferred and nonpreferred legs was the same but the torque ratio differed indicating that the hamstrings provided proportionately more work in the NP leg at higher speeds.
对优秀壁球、网球和田径运动员进行的等速测试表明，在以90度/秒的速度测试峰值力量（扭矩）时，腘绳肌与股四头肌的比例公认在60%至80%之间。然而，在高达300度/秒的更高测试速度下会出现显著差异，腘绳肌变得更加突出，尤其是在非优势（NP）腿中（p小于0.001）。不同运动项目之间没有显著差异，且存在较大的个体差异。对（每千克体重每秒的功）功率的分析表明，田径运动员的功输出显著高于壁球和网球运动员（p小于0.01），但是，与腘绳肌/股四头肌比例不同，优势（P）腿和非优势腿之间没有显著差异。最大功率输出在220至250度/秒左右达到。优势腿和非优势腿之间的功率相同，但扭矩比例不同，这表明在更高速度下，腘绳肌在NP腿中提供的功比例更大。
