This study tries to observe the change of isokinetic muscular function and BMD (Bone Mineral Density) of middle-aged women who received the motion-beat program of 8 weeks of Rhykwon exercising. It had 10 people of motion-beat group and 10 people of general-beat group. They had 8 weeks of Rhykwon exercising program. The results of the study are as follows, First, in the isokinetic strength factor, there were significant differences in the measuring time and interaction effect right side flexor. There were significant difference in measuring time at left extensor and flexor. Second, there were significant difference at the measuring time of leftㆍright side extensor for isokinetic muscular power factor. There were significant differences at measuring time and interaction effect at leftㆍright side flexor. Third, there were significant difference at the measuring time of right side extensor for isokinetic muscular endurance factor. There were significant difference at measuring time and community groups of right side flexor showing the effect of the motion-beat. There were significant differences at measuring time and interaction effect of the left side flexor. Fourth, the two groups showed positive change in the BMD. But there weren’t significant statistical difference. Therefore, the 8 weeks of Rhykwon exercising program and motion-beat for middle-aged women partially affected the isokinetic muscular function and BMD. It maximized the efficiency of the exercise and became basic materials for various programs in social physical education fields.
