ABSTRACT

PURPOSE: This study was examined the effects of aerobic exercise using a step box and lower extremity strengthening exercise with an elastic band on the balance ability and lower extremity muscular strength in elderly subjects. METHODS: Forty-one healthy adults were randomly divided into experimental group 1 (Exp 1, n=14), experimental group 2 (Exp 2, n=14), and a control group (n=13). The Exp 1 conducted lower limb strengthening exercise using an elastic band and the Exp 2 performed aerobic exercise with a step box 50 minutes per day, twice per week, for eight weeks. RESULTS: There was significant increase in the Exp 1 and Exp 2 in comparison of the change of lower limb muscle strength according to measurement time (p<.05). But there was no significant difference according to intervention methods. In one-leg standing test change among the three groups after the intervention, the Exp 1 and Exp 2 saw significant improvement compared to the control group (p<.05) but there was no significant difference according to intervention methods. The change of the functional reaching test results, the Exp 1 and Exp 2 saw significant improvement according to the time of measurement. In the change of the Timed Up and Go test, there was significant improvement in the Exp 1 and Exp 2 compared to the control group (p<.01), but there was no significant difference according to intervention methods. CONCLUSION: Exercise to lower extremity strengthening program accompanied with aerobic exercise is considered more effective in dynamical balance and ability to walk.
