The purposes of this study were to examine the effects of gravity and sport on the hamstrings-quadriceps strength relationships. The peak torques at four speeds of isokinetic exercise (60, 180, 240, 300 degrees /sec) were determined for 20 male college track athletes, including 10 sprinters and 10 distance runners. The runners were tested on a Cybex(R) II isokinetic dynamometer. Peak torque measurements were corrected for the effects of gravity. Results of the present study showed that: 1) the effects of gravity significantly alters the hamstrings to quadriceps ratio at all velocities, and 2) there is no statistically significant difference in the hamstrings quadriceps strength ratios between the two groups of athletes except at 300 O/sec. At that speed, sprinters had a higher ratio than distance runners. J Orthop Sports Phys Ther 1986;7(5);232-235.
本研究旨在探讨重力和运动对腘绳肌-四头肌力量关系的影响。对 20 名男性大学生田径运动员（包括 10 名短跑运动员和 10 名长跑运动员）进行了等速运动（60、180、240、300 度/秒）的 4 种速度的峰值扭矩测试。运动员在 Cybex（R）II 等速测力计上进行测试。峰值扭矩测量值经过重力效应校正。本研究结果表明：1）重力的影响显著改变了所有速度下的腘绳肌与四头肌比率；2）两组运动员的腘绳肌-四头肌力量比率除在 300 度/秒外，无统计学差异。在该速度下，短跑运动员的比值高于长跑运动员。J Orthop Sports Phys Ther 1986;7(5);232-235.
