Removal of weight bearing of skeletal muscle by limb immobilization produced atrophy of slow twitch muscles fixed at resting length. The initial decreases of muscle artrophy started with an early, large decrease in protein synthesis rate. Muscle strength and enzyme activity changes induced in skeletal muscle as a result of joint immobilization, glycolytic enzyme activity in fast muscle and oxidative enzyme activity in slow muscle decreased remarkably following hypodynamia, immobilization. However, The aim of present paper was to investigated the effects of one leg immobilization during the two weeks to the muscle strength and serum enzyme activities. The results was summarized as follows; 1. Immobilized leg was significantly decreased muscle strength(ext;27.9% flx:8.5%), power(ext:15.5% flx:6.5%) and muscle endurance(ext:8.8% f1x;10.3%) which was 50 repetition work capacity at 180 degree/sec, during the two week immobilization, opposed leg was slightly increased strength, power and muscle endurance to extensor and flexor muscle. 2. CPK activity in serum was increased significantly in the control group, but that was decreased in the experimental group. GPT and GOT was showed to be decreased slightly in the control group but, to be increased the experimental group. 3. LDH was decreased after two weeks immobilization control and experimental groups. After two weeks immobilization, LD1 isozyme in experimental group was down significantly(P$lt;0.01) lower than that of control. LD4 and LD5 isozymes revealed to be increased significantly after two weeks in the experimental group. Therefore sudden stop by immobilization effected to decrease muscle strength, power and endurance including enzyme activities to influence subtly energy supplement. So we should study not to damage injured athletes and the off season.
