本研究的目的是确定和比较排球和篮球运动员在不同速度下腘绳肌和股四头肌的最大自主扭矩峰值，以及这些肌肉之间的扭矩比。20名男子排球运动员、20名男子篮球运动员和20名对照者在角速度为600°、180°和300°s -1时使用等速测力仪进行评估。在排球运动员和篮球运动员之间，除了股四头肌在300°s -1时（排球：139.9±0.7 Nm，篮球：117.2±1.9 Nm）外，股四头肌和腘绳肌的同心峰值扭矩没有显著性差异。平均腘绳肌/股四头肌（H/Q）比在60°s -1时彼此相似。排球运动员和篮球运动员在180°s -1时的H/Q肌比无显著差异。与篮球运动员和对照组相比，排球运动员仅在300°s -1时表现出更大的差异（p= 0.001和p= 0.000）。我们的数据表明，运动的需求似乎会影响等速同心H/Q比。
The aim of this study was to determine and compare the maximal voluntary peak torque of the hamstring and quadriceps muscles, and the torque ratio between these muscles in volleyball and basketball players across a spectrum of speeds in their dominant legs. Twenty male volleyball players, 20 male basketball players, and 20 controls were evaluated using an isokinetic dynamometer at angular velocities of 60o, 180o and 300°s -1 . No significant quadriceps and hamstring muscles concentric peak torque was found between volleyball and basketball players with the exception of quadriceps at 300°s -1 (volleyball: 139.9±0.7 Nm, basketball: 117.2±1.9 Nm). The mean hamstring/quadriceps muscles (H/Q) ratios at 60°s -1 were similar to each other. No significant differences were found between volleyball and basketball players for H/Q muscles ratio at 180°s -1 . Volleyball players demonstrated higher differences compared to the basketball players and control groups only at 300°s -1 (p=.001 and p=.000, respectively). Our data suggest that the sport’s demands seem to influence isokinetic concentric H/Q ratio.
