A mathematical analysis of knee extension and flexion exercise is presented to determine effectiveness in strengthening the quadriceps and hamstring muscles. A quantitative relationship between the quadriceps force and the hamstring force is obtained for several variations of the exercises. The theoretical results are supplemented with experimental studies performed on subjects exercising with the Tekdyne Incentive Dynamometer.
本文对膝关节伸展和屈曲运动进行了数学分析，以确定其在增强股四头肌和腘绳肌方面的有效性。针对几种不同的运动变化，得出了股四头肌力量和腘绳肌力量之间的定量关系。理论结果辅以对使用泰克迪恩激励测力计进行运动的受试者所做的实验研究。
