This study concerns norm-referenced criteria for isokinetic strength of the lower limbs for the Korean high school baseball players. Two hundred one high school baseball players were participated in this study. They didn``t have any medical problem at the lower limbs. Each test was conducted four times in the ankle plantar flexion/dorsiflexion test at 30o/sec speed, knee flexion/ extension test was conducted four times at 60o/sec speed. Humac Norm (CSMI, USA) system was used to obtained the value of peak torque, peak torque % body weight. The results were presented as a norm-referenced criterion value using 5-point scale of cajori, by 5 group (6.06%, 24.17%, 38.30%, 24.17%, and 6.06%) and a few suggestions from this study as follows. The provided criterion of peak torque and peak torque % body weight are very useful information for baseball palyers, baseball coach, athletic trainers and sports injury rehabilitation experts, to utilize as an objective clinical assessment data.
