Abstract
[Purpose] The purpose of this study was to determine the effects of a 12-week program of light exercises in the seated position on lower body muscular strength and functional fitness of frail older adults. [Subjects and Methods] Sixty-two individuals (mean age = 72 yr) were assigned to two groups: resistance (R) and balance (B) exercise groups. The resistance group performed exercise using an elastic band and a pneumatic exercise kit, and the balance group performed exercise using another pneumatic exercise kit. Lower body strength of knee extension (KE), ankle dorsal extension (AE) and flexion (AF), hip adduction and abduction, and functional fitness were assessed at pre- and post-test. [Results] Significant improvement in the R group was noted in AF, KE, while the B group showed significant changes in KE, AE and single leg balance, but not in functional reach. [Conclusion] Light intensity exercise programs in the seated position were effective at improving the lower body strength of frail older adults.
