Abstract

The purpose of this study was to investigate the effects of angular velocity on muscle strength and blood constituent. Subjects was classified into two groups, which were $60^{\circ}/sec$ angular velocity group (n=8), and $240^{\circ}/sec$ angular velocity group (n=8). Each group was applied to perform the isokinetic exercises on extensor muscle group for each 7 times in 10 set (3 days per a week for 3 weeks). Muscle strength was measured using peak torque of quadriceps femoris and blood constituent was measured using RBC, WBC and Hb. The peak torque was more significantly increased after 3 weeks application of $60^{\circ}/sec$ angular velocity group than $240^{\circ}/sec$ angular velocity group. The RBC and Hb were more significantly increased after 3 weeks application of $60^{\circ}/sec$ angular velocity group than $240^{\circ}/sec$ angular velocity group. But WBC was more significantly increased after 3 weeks application of $240^{\circ}/sec$ angular velocity group than $60^{\circ}/sec$ angular velocity group. These results indicate that $60^{\circ}/sec$ angular velocity isokinetic exercise application were effective treatment strategy on increase of muscle strength. But $240^{\circ}/sec$ angular velocity isokinetic exercise application were effective treatment strategy on immune protect system.
