Abstract
This article reviews the decline of physical strength with aging, and exercise for preventing the decline as well as appropriate uptake of nutritions. Appropriate exercise based on appropriate uptake of nutritions is effective for preventing the decline in physical strength. Especially for the institutionalized elderly persons who showed extremely lower daily activities, constant exercise played an effective role in the maintenance of physical strength, even though they had no custom of doing exercises such as sports activity or physical labor. Energy uptake exceeding the energy expenditure may induce obesity, thereby potentially aggravating the decline in physical strength.
