| 摘 要： | 本研究旨在探讨跳远运动员膝关节屈伸肌群形态与专项力量间的相互关系。肌肉形态测量采用CT断层扫描,力量测试采用美国Cybex-Norm等速测力系统,数据处理采用SPSS11.0软件。研究结果表明:从形态上看,一级跳远运动员大腿肌肉各相应断面面积明显大于二级运动员,且右侧略大于左侧;在相同测试速度下,一级运动员肌肉收缩力量大于二级运动员,且右侧略大于左侧;跳远运动员在低速屈膝、伸膝时,肌肉力量与其横断面积密切相关。

| Abstract: | This thesis aims to study the relation between the cross-section and force of knee joints' flexors and extensors.CT scans the cross-section of muscles,the force of the muscles is measured on Cybex-Norm and All data are analyzed statistically by using SPSS11.0.The result shows:Looking from form,every corresponding area of section of the first class long jumper's thigh muscle is obviously greater than the second grade ones'.And the right side is slightly greater than the left side.Under the same speed of testing,First grade athletes' muscle shrinks strength is greater than that of the second grade ones'.And the right side is slightly greater than the left side;When the long jumpers go down on their knees and stretch at a low speed,the strength of the muscle is closely related to area of transecting. |
