ARMWRESTLING EXERCISE AND SHOULDER INTERNAL ROTATION STRENGTH

Abstract

The purpose of this study was to investigate the differences in shoulder internal rotation strength between winner and loser during armwrestling. Prior to the armwrestling experiment, subjects would be tested for strength of shoulder internal rotation with 45 °/sec and 60 °/sec by isokinetic dynamometer. The results showed that the strength of shoulder internal rotation at angular velocity of 45°/sec and 60°/sec had significant difference between winner and loser (P <.05). Overall the mean peak torque values of shoulder internal rotation were significantly higher in winner than in loser. However, the participants whose shoulder internal rotators had been trained might be able to reverse the situation.
