Abstract

OBJECTIVE
To obtain the comparison data of the shoulder strength between handball players of college and general college students. METHOD: Fifteen subjects from each group, college handball players and general college students groups were tested. Peak torque, peak torque ratio of internal rotator to external rotator, peak torque to body weight ratio and average work during isokinetic exercise were studied.
RESULTS
All of the parameters tested in handball players of college were greater than those of general college students. The peak torque in handball players was greater than that of general college students at 60o/sec, 180o/sec, which was statistically significant (p<0.05). The peak torque ratio of internal rotator to external rotator in dominant side of handball players was greater than the college group (p<0.05). The peak torque to body weight ratio at 60o/sec did not show significant differences between handball players of college and general college students. The average power at 60o/sec did not show significant differences between the two groups.
CONCLUSION
The values of peak torque ratio of internal rotator to external rotator of the shoulder joint in dominant side of handball players were greater than those of the general college students. So it was suggested this result have to be considered in selecting handball players and exercise prescription.
