The relationship between tissue damage and changes of mechanical properties of. skeletal muscle with strain injury was discussed. Tibialis anterior muscle was extended 20, 25 or 30 % at 200 mm/sec to induce tissue damage. From pathological view points, severity of tissue damage could be classified into three grades and we could find a threshold of strain injury based on the relation between applied energy during injury-inducing process and the injury severity. We also evaluated the effects of strain injury on isometric contraction force. The results of biomechanical tests showed that the maximum contraction forces of 25%- and 30%-stretched muscles decreased. It indicates the injury severity could be related with biomechanical function of skeletal muscle.
