Peak torque, peak torque to body weight ratio, angle at peak torque, peak torque acceleration energy, average power, endurance ratio and peak torque ratio between antagonists during isokinetic exercise were studied in order to obtain the normal data of shoulder girdle muscles in 40 young healthy adults.

1) The values of peak torque and peak torque to body weight ratio at 60°/sec were greater than those of 150°/sec, which were statistically significant(p=.0001).

2) The values of peak torque acceleration energy and average power at 150°/sec were significantly greater in males than those of females(p=.0001).

3) The values of peak torque angle at 60°/sec and 150°/sec showed no significant differences between both sexes or sides.

4) The comparison of peak torque in antagonists at 60°/sec and at 150°/sec showed greater values in abductors and extensors than those of adductors and flexors respectively, which did not show significant differences.

5) There were significant correlation relationships between peak torque and peak torque acceleration energy and average power at 150°/sec(p<.05).
