Eighteen healthy college students participated in the experiment for all conditions of meridian point irradiation (MPI), femurs muscles irradiation (FMI), and no irradiation (NI). They all took isokinetic knee extension and flexion tests (IK test) before and after strenuous exercise up to exhaustion. Each subject was irradiated at the meridian point or in femurs muscles after the second IK test. The third IK test was carried out after ten-minutes rest. The effects of PL irradiation were confirmed on the recovery rate of muscle fatigue in knee extension motion with high load intensity (PT 60 d/s and TW 60d/s : MPI, FMI NI, p0.05 16.2%, 13.4%8.5%, and 16.1%,14.1%8.3%, respectively). Also, in flexion motion,significant differences in the recovery-degree for each condition were found,and the effect of PL irradiation was suggested. There was no difference between the effect of MPI and FMI. In addition, subjective
