躯干屈伸肌群等速肌力和耐力的初步研究

A Primary Study of Isokinetic Muscle Strength and Endurance of Trunk Extensors and Flexors

采用Ｃｙｂｅｘ－ＴＥＦ系统对４０例年轻人躯干屈伸肌群的肌力和耐力进行等速测试。结果表明：随着测试速度的增加，女性屈伸肌群和男性伸肌群的ＰＦ值逐渐降低，而男性屈肌群ＰＴ值随速度的变化不大。两性伸肌群的ＥＲ和女性的ＲＲ均低于屈肌群。本研究提供了一组正常年人的数据，对了解其躯干肌肉功能特点、指导运动训练及预防下腰痛和运动伤病具有参考意义。

Isokinetic muscle strengthe an endurance of the trunk extensors and flexors in 4O college students were tested with Cybex-TEFunit.The results indicated that the peak torque values of female extensors, female flexors and male extensors declined with increasing of testing velocity velocity, but no such change was seen in male flexors. The endurance ratio of extensors in both sexes and the revoveryat of extensors in the female were significantly lower than the flexors . These data of the healthy young adults could provide someknowledges of the characteristics of the trunk muscle and be beneficial to the sports training as well as the prevention of the low back pain and trunk trauma.
