To compare the differences in the concentric hamstrings:quadriceps (H:Q) ratio among athletes in different sports at 3 velocities. DESIGN AND SETTING: We measured the H:Q ratio of both knees using the Biodex Pro Isokinetic Device. SUBJECTS: Eighty-one male and female collegiate athletes. MEASUREMENTS: We performed analyses for sport, velocity, and side of body for each sex. To compare the means of the concentric H:Q ratios for mean peak torque and mean total work, a 2 x 3 x 4 mixed-factorial analysis of variance was computed for women and a 2 x 2 x 3 mixed-factorial analysis of variance was computed for men. RESULTS: We observed no significant interactions for men and women for the concentric H:Q ratio for mean peak torque. There was a significant mean difference among velocity conditions and a significant difference for men with respect to velocity. No significant differences were found for side of body or sport. CONCLUSIONS: The H:Q ratio increased as velocity increased. No differences existed for the H:Q ratio for sport or side of body.
比较不同运动项目的运动员在三种速度下的股后肌群与股四头肌（H:Q）比值差异。
我们使用Biodex Pro等速装置测量了双膝关节的H:Q比值。
81名男女大学生运动员。
我们对每个性别的运动项目、速度和身体侧别进行了分析。为比较平均峰值扭矩和平均总功的向心H:Q比值的均值，对女性进行了2×3×4混合因子方差分析，对男性进行了2×2×3混合因子方差分析。
我们观察到，在平均峰值扭矩的向心H:Q比值方面，男性和女性均未出现显著交互作用。速度条件之间存在显著的均值差异，男性在速度方面也存在显著差异。在身体侧别或运动项目方面未发现显著差异。
H:Q比值随速度增加而升高。在运动项目或身体侧别方面，H:Q比值不存在差异。
