This study investigated the effects of two exercise programs, which include exercise methods to increase muscle strength, balance, and endurance, on the balance ability and fall efficacy of elderly people, and the differences in effects according to preference. Twenty-one elderly people were divided into a group using assistive devices using elastic bands (Experimental Group 1) and a group using the body (Experimental Group 2) and an exercise program was conducted for 4 weeks. The single leg stand (SLS) and functional reach test (FRT) were used to evaluate the elderly's balance ability, and the fall efficacy scale (FES) was used to evaluate the degree of fear of falling. A pre-evaluation was conducted after a 2-week integrated exercise program, and a post-evaluation was conducted after applying the exercise program for 4 weeks. In the study results, within-group SLS, FRT, and FES analyzes all showed statistically significant improvement in the post-assessment compared to the pre-assessment. However, there were no significant differences in the comparison between groups regarding exercise program and between groups according to preference. In conclusion, in order to increase the balance ability and fall efficacy of the elderly, an exercise program must be applied, and it is necessary to use a program that is easy to apply and includes exercise methods that the elderly can easily perform.
