The purpose of this study is to examine the positive effects of each of these three exercises on the physical elements of the aged and help them to choose an effective exercise method suited to their needs. The subjects of this study included 46 elderly women(age 70 or older) living in B Metropolitan City. The subjects were divided into three groups of ball(n=17), band(n=15) and yoga(n=14). Exercises were conducted for 50-60 minutes a day and three times a week for a period of 12 weeks. The ball group showed significant improvement(p<.001) in chair stand, 2kg dumbbell curl, chair sit-and-reach, 2.44m up-and-go and 6-minute walk, and significant improvement(p<.01) in back stretch. The band group showed significant improvement(p<.001, p<.01) in chair stand and 2kg dumbbell curl, and significant improvement(p<.05) in chair sit-and-reach and 2.44m up-and-go. The yoga group showed significant improvement(p<.001) in chair stand and 2kg dumbbell curl, and significant improvement(p<.05) in chair sit-and-reach and 2.44m up-and-go. In terms of comparison between groups, yoga group showed significant improvement (p<.05) in chair stand compared with ball group and band group showed significant improvement(p<.001) in 2kg dumbbell curl compared with ball group. The improvement of functional fitness of elderly women through ball exercise, band exercise and yoga is thought to have positive influences on their quality of life.
