| 摘 要： | 通过对运动员股四头肌、股后肌群不同断面面积及髋关节屈伸力矩的测量,探索不同项目运动员大腿肌肉不同断面的面积大小与髋关节屈伸力量相关的内在规律。肌肉横断面积采用螺旋CT进行断层扫描,影像分析采用MoticImagesAdvanced3.0测试系统软件,力量测试采用美国Cybex-Norm等速测力系统,数据处理采用SPSS8.0软件。结果表明:1)运动员股四头肌、股后肌群不同断面面积与髋关节屈伸力矩的相关性主要体现在大腿的中、上段,髋关节屈时的相关以上段为主,伸时的相关以上、中段为主。2)足球运动员在中、高速运动左髋屈时,其屈肌的力量与大腿上段肌肉的横断面积密切相关,而右侧在低、高速也具有同样的相关;而足球运动员在中、高速运动左髋伸时,其伸肌的力量与大腿中段肌肉的横断面积密切相关。速滑运动员的相关性以右侧伸肌相关最明显。

| Abstract: | By means of measuring the cross-sectional areas and force of hip joint's flexors and extensors of 14 systematically trained athletes,the relative inner relationship between the different cross-sectional areas and force of the muscles in athletes of different sports events is studied.CT scans the cross-sectional areas of thigh.By using Motic Images Advanced 3.0 analysing systematical software,the cross-sectional areas of hip joints'flexors and extensors are calculated.The strength of the muscles is measured on Cybex-Norm.All data are analysed statistically by using SPSS.8.0.The findings indicate that 1) the correlation of force to cross-sectional areas of hip joints'flexors and extensors lies primarily in the middle,upper parts of thigh.When hip joints flex,the correlation lies mainly in the upper parts of thigh and the upper,middle parts of thigh while extending.2) When football athletes flex their left hip joints at middle,high speeds,the strength of flexors is closely related to the cross-sectional areas of the upper parts of thigh and so do the right thigh at lower,high speeds.But when they extend their left hip joints at middle,high speeds,the strength of extensors is closely related to the cross-sectional areas of the middle parts of thigh.As for athletes of speed skating,the correlation can be obviously found in right extensors. |
