The Effect of Low-Intensity Aerobic Exercise on Muscle Strength, Flexibility, And Balance Among Sedentary Elderly Persons

Abstract

An experimental group of 20 elderly subjects participated in 8 weeks of low-intensity aerobic exercise while 27 subjects in a comparison group maintained their usual level of activity. The program consisted of stretching and strengthening chair exercises. A significant difference between the groups was found for flexibility of the ankles and the right knee. No significant difference was found between the groups for muscle strength or balance, although the experimental group improved their balance by 22%.
