摘　　要：背景:等速测试系统作为一种评价人体肌肉功能水平的研究方法和手段,在研究中得到了越来越广泛的应用,但运用等速肌力测试研究大学生髋关节屈伸肌群发展影响的报道并不多见。目的:采用等速肌力测试系统评估大学生髋关节屈伸肌力。方法:志愿参加测试的大学生男女各20名。采用澳大利亚Kylingk公司生产的"Kinitech"等速肌力测试系统,按照测试要求对参试者髋关节进行测试,测试顺序为先向心后离心。测试速度为慢速60(°)/s,中速120(°)/s,快速240(°)/s。观察髋关节屈伸肌群的峰力矩、相对峰力矩、总功、相对总功。结果与结论:在相对应的角速度下,男性峰力矩和相对峰力矩均大于女性(P<0.01)。角速度为60,120,240(°)/s时,男性屈肌峰力矩均小于伸肌峰力矩,而女性屈肌峰力矩大于伸肌,但差异无显著性意义(P>0.05)。在相对应的角速度下,男性总功及相对总功均大于女性(P<0.01)。男性屈肌总功及相对总功均小于伸肌[角速度为60,120(°)/s时,P<0.01;角速度为240(°)/s时,P<0.05)];女性屈肌总功及相对总功也均小于伸肌[角速度为60(°)/s时,P<0.01);角速度为120,240(°)/s时,P<0.05)]。提示髋关节屈伸肌群在相对应的角速度下,男性峰力矩、相对峰力矩、总功、相对总功均大于女性;男女峰力矩、相对峰力矩、总功、相对总功随着测试角速度的增大而减小;在对应的指标下,男性的值大于女性。BACKGROUND： Isokinetic test system has been widely used to evaluate the muscle function levels. Whereas, the reports concerning effect of sport training on the development of muscle strength of hip joint in college students using isokinetic testing are few. OBJECTIVE： To assess the extensor and flexor muscle strength of hip joints in college students with isokinetic testing system. METHODS： Totally 40 volunteers, including 20 male and 20 female students were selected. Kinitech isokinetic testing system, produced by Australian Kylingk Company, was used to test the flexion and extension muscle of hip joints as the sequence of centripetal followed by centrifugal. The test speed was 60 （°）/s as slow speed, 180 （°）/s as middle speed, 240 （°）/s as high speed. Peak torque （PT） and relative values of extension and flexion muscles, total power （TP） and relative total power were measured. RESULTS AND CONCLUSION： At the respective speed, PT and relative values of female students were greater than that of female students （P〈0.01）. At the speed of 60, 120 and 240 （°）/s, flexor PT was smaller than that of extensor PT in male students, which was opposite in the female students, but the difference had no significance （P〉0.05）. At the respective speed, TP of males were greater than that of female students （P〈0.01）. In male students, TP and relative values of flexor were smaller than extensor at speed of 60 （°）/s and 120 （°）/s （P〈0.01）, and had difference at speed of 240 （°）/s （P 0.05）. In female students, TP and relative values had significant difference between flexor and extensor at speed of 60 （°）/s （P 0.01） and at speed of 120 （°）/s and 240 （°）/s （P 0.05）. At the respective speed, PT and relative values, TP and relative values in male students are all greater than females. These values decrease with the speed increasing. At the respective values, values of male students are bigger than females.
