排球、足球运动员膝关节等速向心肌力测试比较研究

Concentric Quadriceps and Hamstring Isokinetic Strength in Volley and Soccer Players

通过应用Cybex-6000等速测试系统对28名排球运动员和46名足球运动员(5名守门员、16名后卫、15名中场、10名前锋)膝关节肌力进行测试,以探讨排球、足球两个不同项目运动员膝关节肌力特征及差别。测试结果表明:排球运动员优势腿、非优势腿股四头肌峰力矩在360°/s和90°/s上均大于足球运动员,而排球运动员腘绳肌峰力矩与足球运动员无明显差异;而排球运动员双侧腘绳肌峰力矩(90°/s)差异程度显著小于足球运动员;排球运动员在90°/s的速度下测得的股四头肌/腘绳肌峰力矩比值(H/Q)要显著低于足球运动员随着角速度的增快(90°/s→360°/s),并且排球运动员和足球运动员股四头肌/腘绳肌峰力矩比值(H/Q)均随之增大;没有发现不同位置的球员之间膝关节等速肌力测试结果存在很大差异。

The aim of the study was to describe and to compare isokinetic strength profiles（peak torque,bilateral strength differences between D/ND leg（BD） and hamstrings/quadriceps（H/Q） ratio）in volley and soccer players.Twenty-eight volley players and forty-seven soccer players（goalkeepers,n=5;defenders,n=17;midfielders,n=15;forwards,n=10） were evaluated using an isokinetic dynamometer（Cybex-6000）.Results：No significant BD were found between soccer and volley players with exception of hamstrings at 90°·s-1.The H/Q ratio was significant lower in volley players at 90 °/s-1.No significant differences were found for BD in soccer players of different positional roles.
