摘　　要：背景:在等速肌力测试研究中关于运动训练对青少年肌群发展影响的报道很少。目的:采用等速肌力测试系统评估不同群体青少年肩、髋、膝3关节肌力。设计、时间及地点:对比观察,试验于2006-10/12在河北师范大学体育学院实验室进行。参试者:随机抽取石家庄4所中学不参加训练的志愿者30人,男女各15人,作为普通组;抽取石家庄市体校进行短跑训练的志愿者30人,男女各15人,作为训练组。方法:运用澳大利亚Kylingk公司生产的"Kinitech"等速肌力测试系统分别对日常参加短跑训练和不参加训练的健康男、女中学生的肩、髋、膝3关节,进行60,120,240(°)/s3种不同角速度的测试。主要观察指标:肩、髋、膝3关节屈伸肌群的峰力矩。结果:纳入不参加训练的志愿者和进行短跑训练的志愿者各30人,均进入结果分析。①男子训练组与普通组肩关节60,120,240(°)/s运动时峰力矩相比,差异均有非常显著性意义(P<0.01),女子训练组与普通组肩关节的峰力矩相比差异没有显著性意义(P>0.05)。②男子训练组与普通组髋关节60,120,240(°)/s屈时峰力矩相比,差异具有显著性意义(P<0.05,P<0.01),女子训练组与普通组左、右髋关节峰力矩相比差异无显著性意义(P>0.05)。③男、女训练组与普通组膝关节以60,120,240(°)/s屈、伸时峰力矩相比差异均有显著性意义(P<0.05,P<0.01)。结论:短跑运动训练可促进对青少年男子肩、髋、膝3关节肌肉力量的增长及屈伸肌群的协调发展。该训练对青少年女子肩、髋关节作用不明显。BACKGROUND： In isokinetic testing researches, the effect of sport training on the development of teenager muscle groups is less reported. OBJECTIVE： To assess the muscle strength of shoulder, hip and knee joints in different teenager populations with isokinetic testing system. DESIGN, TIME AND SETTING： The contrast observation was performed at the laboratory of Institute of Physical Education, Hebei Normal University between October and December 2006. PARTICIPANTS： Control group included 30 volunteers without sport training randomly selected from four middle schools in Shijiazhuang, 15 male and 15 female; training group included 30 volunteers with sprint training randomly selected from Shijiazhuang Sports School, 15 male and 15 female. METHODS： We used Kinitech isokinetic testing system （Kylingk, Austrilia） to test the shoulder, hip and knee joint of the 60 participants according to 3 different angular velocities： 60（°）/s, 120 （°）/s and 240（°）/s. MAIN OUTCOME MEASURES： Peak torque （PT） values of extensor and flexor groups in shoulder, hip and knee joints. RESULTS： The 60 volunteers were all included in the result analysis. PT values of shoulder joints were bigger in the male training group than in the control group at 60（°）/s, 120 （°）/s and 240 （°）/s （P 〈 0.01）, while the differences between the female training group and the control group were not statistically significant （P 〉 0.05）; PT values of hip joints were bigger in the male training group than in the control group at 60（°）/s, 120（°）/s and 240（°）/s （P 〈 0.05, P 〈 0.01）, while the differences between the female training group and the control group were not statistically significant （P 〉 0.05）; PT values of knee joints were bigger in the male and female training group than in the control group at 60 （°）/s, 120 （°）/s and 240 （°）/s （P 〈 0.05, P 〈 0.01）. CONCLUSION： Sprint exercise has a distinctively positive effect in boys on t
