Abstract

Purpose：The purpose of this study was to investigate the effects of angular velocity on muscle strength of biceps brachii. Methods：Subjects was classified into two groups, which were $60^{\circ}/sec$ angular velocity group(n=15) and $240^{\circ}/sec$ angular velocity group(n=15). Each group was applied to perform the isokinetic exercises on flexion muscle group for each 10 times in 3 set(3 days per a week for 2 weeks). Muscle strength was measured using peak torque of biceps brachii. Results：The results were as follows: The peak torque was significantly increased after $60^{\circ}/sec$ angular velocity isokinetic exercise application(p<.05), however, it was not significantly after $240^{\circ}/sec$ angular velocity isokinetic exercise application(p>.05). Conclusions：This study showed that $60^{\circ}/sec$ angular velocity isokinetic exercise application were effective treatment strategy on increase of muscle strength. Therefore, it could be considered as a treatment method in the athlete and patients with musculoskeletal disease.
