| Research Abstract |
The purpose, of this study was suggestion of a new strength training program for elderly based on results of the quantitative measurement of lower extremity muscles.
In 2003, we measured the muscle cross-sectional areas of knee extensors and flexors and ankle dorsiflexors and plantar flexor in men and women from the 5^<th> decade to the 9^<th> decade using our development an ultrasonographic system. Age-related change in different muscle groups of the lower extremity was examined in a obtained ultrasonographical image. Functional extensor and flexor muscle groups in the thigh and the leg showed differing patterns of age-related muscle less in elderly subjects. A strength training program of elderly was devised based on these results.
In 2004, a devised strength training program was performed for eight months by elderly subjects and the training effect was investigated. As a insult, increase of muscle mass of the thigh and improvement of knee extention strength were shown. The devised program in this study was strength training, but the interesting results that a tendency to decrease was shown in body weight, percent fat, waist and hip were obtained.
It will be thought that development of a training program for elderly people individual is necessary in future.
