通过运用ISOMED2000多关节等速测力系统对我国国家男子短道队运动员膝、踝关节肌肉力量进行测试和分析，针对运动员力量特征和表现，深入分析短道速度滑冰500m项目特征，增强训练的优化性和对项目制胜规律的认识。结论：（1）优秀男子短道运动员在相对峰力矩和相对总功指标上并没有表现出非常高的能力，在平均功率指标上表现出较好的随速度增加而提高的趋势，但是屈伸比指标远远低于国内外优秀运动员，由于最大峰力矩角度指标前人研究较少，本研究结果可作为其他研究的基础和支撑；（2）膝伸肌群峰力矩角度（高速）、膝屈肌群平均功率（中速）和膝屈肌群相对峰力矩（低速）3组数据进入与500m成绩的逐步回归方程，相关系数为0．955，决定系数为0．912；（3）优秀短道运动员500m成绩的力量决定因素主要为高速度区最大力量发力时机、中速度区的肌肉爆发力以及低速度区最大力量储备，膝关节肌群力量相对踝关节在500m项目中更加重要。

The knee and ankle muscle strength of elite male skating athletes was measured and analyzed by ISOMED 2000 isokinetic testing system. Based on the features of athletes＇ muscle strength, the study aims to find the differences and drawbacks in short track speed skating athletes and to make the further discussion on the laws and determinations of the event. The main conclusions were as follows ：（ 1 ） There was no outstanding performance in peak torque and total work of short track skaters, and even worse in flex/ext, but they did better in average power at high speed; （2） The angle of peak torque （fast）, average power （middle） and peak torque （low） were high correlated to 500m performance, and the correlation and determination were 0.955, 0.912 respectively. 500m performance is determined by that the muscle performances of fast speed, which including force opportunity, power ability and max-strength ability; the knee muscles are more important than the ankle＇ s; the strength with technique are the core factor for performance.
