The purpose of this study was to determine the isokinetic strength of the quadriceps femoris and hamstring muscles in high school-aged students. Forty-seven 15- to 18-year-old high school volunteers served as subjects. Data were gathered on each subject by a questionnaire, lower extremity musculoskeletal assessment, and isokinetic testing of the two muscle groups at 60 degrees/sec and 180 degrees/sec. This study found no age effect on peak torque and no significant differences in peak torque between dominant and nondominant limbs. Significant differences (p less than .001) occurred between the isokinetic strength of male and female subjects. The average hamstring muscle to quadriceps femoris muscle torque ratio was 57 percent at 60 degrees/sec and 70 percent at 180 degrees/sec. A value of foot pounds of torque per kilogram of body weight was provided as a guideline for clinicians. This investigation supports several findings already reported for other age groups.
本研究的目的是确定高中生股四头肌和腘绳肌的等速肌力。47名15至18岁的高中志愿者作为研究对象。通过问卷调查、下肢肌肉骨骼评估以及对两组肌肉在60度/秒和180度/秒时进行等速测试，收集每个研究对象的数据。本研究发现年龄对峰值扭矩没有影响，优势侧和非优势侧肢体的峰值扭矩也没有显著差异。男性和女性研究对象的等速肌力之间存在显著差异（p小于0.001）。腘绳肌与股四头肌的扭矩比在60度/秒时平均为57%，在180度/秒时为70%。每千克体重的英尺磅扭矩值为临床医生提供了一个指导标准。本调查支持了已报道的其他年龄组的多项研究结果。
