Abstract AIM:To detect the muscle strength and endurance of healthy young people with diferent sport levels using isokinetic testing technique,so as to explore the characteristics of trunk muscle function. METH0DS:①l20 volunteer freshmen of Grade 2005 including 60 males and 60 females were selected from Capital Institute of Physical Education,and were divided into three groups:general group,physical training group and second—class athlete group(.r/---40, half male and female).Cybex6000 isokinetic testing system(U.S_A)was used.②The muscle strength of flexors and extensors mink muscle was measured at 60。/second and 120。/second and the endurance at 120。/second.⑨Peak torque.flexors/extensors peak torque ratio,endurance ratio and recovery ratio were evaluated. RESULTS:①The peak torque values of male extensors in 3 groups were higher than those of flexors;with the increase in testing velocity.the peak torque value of extensor and flexors was decreased,especially the extensor.The peak torque value of general group was lower than that of physical training group and second class athlete group fP<0.05),and there was no significant difference between the latter two groups rP>0.05).The change in peak torque value of female extensor and flexors was the same to males.The flexors/extensors peak torque ratio at 60。/second and 120。/second of males was less than l,but females more than 1.②Under the same testing velocity,the endurance ratio and recovery ratio ofextensor in 3 groups were higher than those of flexors. CoNCLUS10N:Compared with physical training students and second class athletes.significant decrease in the waist and back muscle strength and unbalance of extensor and flexors strength are found in general students.The muscle strength and endurance of extensor in students with different sport levels are inferior to those of flexors.

摘要 目的:等速测定不同运动水平的健康年轻人躯干屈伸肌群肌力和耐力,了解年轻人躯干肌群的肌肉功能特点。 方法:①受试者为2005级首都体育学院一年级大学生120名,其中男60名,女60名。②按不同标准分为3组,普通非体 育专业的大学生、普通体育教育专业的大学生、获得二级运动员的运动系大学生,每组40名,男女各20名。受试者均自愿 参加测试。测试仪器:使用Cybex6000型等动测力系统(美国)。③测试方法:对健康大学生躯干屈伸肌群的肌力[测试速度为 60(。)/s和120(。)/s]和耐力f测试速度为120(。)/s]等速测试。④测试指标为峰值力矩、躯干屈/伸肌群峰力矩比值、耐力比、 恢复比。 结果:①躯干屈伸肌的峰值力矩值变化趋势:在同一测试速度下,普通组、体教组及二级组男性躯干屈伸肌的峰值力矩值均 伸肌大于屈肌:随着测试速度的增加,躯干屈伸肌的峰值力矩值有下降趋势,伸肌下降最明显:普通组的躯干屈伸肌的峰值 力矩值小于体教组和二级组(P<0.05),后二者差异无显著性(P>0.05):女性3组屈伸肌的峰值力矩值变化同上。在 6o(。)/S和120(。)/s时的躯干屈/伸肌群峰力矩比值,男性均小于l,女性均大于1。②在同一测试速度下,3组男性及女性 躯干伸肌群的耐力比和恢复比均低于屈肌群。 结论:与体育教育专业和二级运动员大学生相比,非体育专业大学生存在着明显的腰背肌力下降,以及躯干屈伸肌力失衡。 不同运动水平大学生伸肌群肌力和耐力弱于屈肌群。 关键词:肌收缩:身体耐力:组织构建

梁题考署:通过等速肌力测试,可以为关节肌力测量提供新的定量评定手一段。目前等速测试研究热点以膝关节等速肌力测试为最多,躯干等速肌力测试.研究较少,且多以围绕腰部各种疾病的.肌力变化为主,而研究健康人群躯干肌力力量的很少。本文通过不同运动水平’的健康年轻人躯干屈伸肌群肌力和耐力‘的等速测定,以探索客观的评价肌力和’耐力的方法。。应用要,占:①男性和
