초록

This study evaluated the muscle mass of legs and simultaneously measured the isokinetic muscular strength and knee extension power targeting 99 women from 50 to 80 in order to review the relevancy with the muscle mass and to provide the basic data about the importance of the muscle of legs and for writing a exercise program. For the measurement of muscle strength of hip joints, an isokinetic dynamometer was used, and dynamic extension (60, deg/s) and dynamic flexion were performed. For the measurement of knee extension power, leg extension power measuring device was used. There was a significant correlation between psoas major muscle, muscle cross-sectional area, and hip joint flexor in the age group of 55-59 (r=.649, p<.05). In addition, There was a significant correlation between the extensor group, and knee extension power in the age group of 60-64 (r=.688, p<.01), 65-69 (r=.629, p<.01), 70-74 (r=.609, p<.001), and 75-80 (r=.773, p<.01). Meanwhile, There was a significant correlation between extensor muscles and knee extension power in the age group of 55-59 (r=.608, p<.05), 60-64 (r=.585, p<.05), 65-69 (r=.597, p<.01). The findings as above imply the muscle of legs is likely to influence knee extension power, the flexion of hip joints, knee extension power, and knee flexion greatly for the middle aged and the aged. Thus, the studies on the exercise programs to increase the muscle of legs are required.
