Peak torque, peak torque, to body weight ratio, peak torque acceleration energy, average work during isokinetic exercise were studied in order to obtain the normal data of the shoulder.

118 subjects were tested, from 3rd to 6th decade.

1) All the values tested in males were greater than those of females.

2) The longer the arm length, the higher the values of peak torque, peak torque acceleration energy, average work.

3) The values of peak torque acceleration energy were declined beyond 5th decade.

4) No significant difference was observed between decades.

5) The ratio of peak torque in antagonists showed no significant difference between decades or sides.

6) There were significant correlation between all items each other measured in this study.
