The purpose of present study was to compare the effects between isokinetic and isotonic trainings with equivalent training doses. Forty two subjects (18-23 yr) were divided into five groups with respect to equal isometric arm strength and arm flexion power: one isotonic training group, three isokinetic training groups trained at the speed of 5, 20, or 30rpm, and one control group. In order to equate the doses of isokinetic and isotonic trainings, impulse was used. All the experimental groups were trained three days per week for four weeks. Isometric arm strength in all training groups was significantly increased (p<0.05 of p<0.01) after training, but the significant difference was not observed among training groups. The arm flexion power of 5 and 20rpm isokinetic training groups was significantly increased after training; the increase in 20 rpm group was superior to that in 5 rpm group. But 30 rpm group did not show any significant increase after training in all experimental conditions. And the arm flexion power of isotonic training group increased only in the minimum experimental load. These results indicate that the isokinetic training at the speed of 20rpm would be superior to the other trainings for the development of the muscular power.
