This study investigated characteristics of shoulder rotators in different levels of tennis players. The analysis focused on the examination of concentric and eccentric strength, and E/C ratio in order to identify the balance of eccentric and concentric strength of shoulder rotators. Results showed that (a) there were significant differences in concentric and eccentric strength of internal rotators between dominant and non-dominant shoulders in three angular velocities at the elite and local tennis players; (b) E/C ratios of shoulder internal rotators of local tennis players at three velocities were significantly higher than those of healthy men.
