| 摘 要： | 为了分析髋、膝关节的等速肌力测量结果及其与百米跑和立定跳远等反映下肢力量的运动项目的关系,应用等速测力系统对36例健康受试者左侧髋关节、膝关节屈伸肌群在不同角速度下收缩的峰力矩、到达峰力矩的关节角度、到达峰力矩的时间等指标进行测量,并统计分析以上指标与百米跑和立定跳远成绩的相关性.结果表明:髋、膝关节屈伸肌群收缩的峰力矩随设定角速度的增大而减小;峰力矩与关节角度、时间等因素存在相关;而与百米跑和立定跳远成绩并不存在有意义的相关性.认为:肌力等速向心收缩测试时关节运动开始点的选取可能对峰力矩的大小产生一定影响;等速肌力测试结果与运动成绩相关不密切,似不适宜用于评价某些项目的实际运动能力.

| Abstract: | The objective of the research is to evaluate the relationship between the isokinetic strength of hip joint, knee joint and the capacity of sprint-run and broad jump. The peak torque, peak angle, and the time to peak torque of hip and knee joint at different velocity are measured with isokinetic dynamometer to (36) subjects, and the correlation of isokinetic strength and sports ability is analyzed. It's found out that the peak torque of flexor and extensor of hip and knee joint have a significantly relationship with the angle and the time; but have no significant relationship with sprint and jump. It can be concluded that the establishment of the starting point may influence the peak torque in isokinitic measurement. The mode of muscle constriction and muscle fiber recruitment at isokinetic condition are very different from the actual practice. It seems that the results of isokinetic measurement may not appraise the actual ability in certain sports events. |
