Isokinetic Evaluation of the Knee Extensors and Flexors in Soccer Players

  The purpose of this study was to 1) evaluate isokinetic muscle strength of the knee extensors and flexors in soccer players, 2) determine if subject"s age, height, and body weight have effects on the results. Twenty one soccer players from middle school(13.3±0.5, N=7), high school(17.1±0.4, N=7), and college(22.7±l.0, N=7) were tested. Right foot was dominant foot of all the subjects in this study. The CYBEX NORM(770) was used for the measurements. The results were as follows: 1) In case of an extensor at all angular velocities(30° / sec, 60° / sec, 120° / sec, and 240° / sec), the college and high school players showed higher peak torque than the middle school players(p＜0.001). 2) In case of an extensor at all angular velocities, the college and high school players showed higher % peak torque than the middle school players(p＜0.05 or p＜0.01). 3) At 120° /sec and 240° /sec, the middle school players showed higher peak torque ratio in antagonists than the other groups(p＜0.05 or p＜0.01).
