Outline of Final Research Achievements

Aging causes difficulties of locomotion such as walking. Their abilities would be related to aging change in leg muscle proportion (LME) which means muscle cross sectional area in the thigh and calf, and their proportion. The present study measured the LME in the male and female adults, especially elderly, using ultrasound system, and showed aging change in the LME. In addition, the study suggested that the LME influences on their locomotion abilities and that can be predicted by walking motion.
