This study proved the effect of isokinetic peak torque of upper and lower body using isotonic exercise program method for 8 weeks. Isotonic exercise and isokinetic exercise are different based on specificity of muscle contraction. The subjects of the experiment were consisted of male university students and average age of subjects was 22.9 ± 1.6. They were trained by isotonic weight training program equipment such as bench press, barbell low, incline press machine, arm curl, squat, leg press, leg extension, and leg curl for three times a week for 8 weeks. Two tests were done; isotonic test used by lRM of all equipment and isokinetic test used by peak torque of knee and shoulder joints (60°/sec, 180°/sec) respectively before and after the exercise. The results were as follows: First, isotonic maximum strength of 1RM on all items showed the average improvement from 10.1-26.6%, which means statistically significant differences (p<.01). Secondly, isokinetic peak torque %BW of the knee showed statistically no significant difference on all items (p>.05). Lastly, isokinetic peak torque %BW of the shoulder increased 22.4% at 60o/sec on the right flexor (F60R), and 17.9% at 180o/sec on the right flexor (F180R) showing statistically significant differences (p<.01). Isokinetic peak torque %BW of the shoulder at 60°/sec on the left flexor (F60L) and those of 180°/sec on the right extensor (F180R) increased respectively 9.7%, 13.4% represented statistically significant differences (p<.05). These data mean results from the differences between the speed of muscle contraction and the exercise load method of Isotonic exercise and isokinetic exercise. Therefore muscle contraction pattern used in muscular strength training program should be considered while measuring muscular strength in the case of applying principle of specificity.
