- Brief Summary
This is a single-blind, cluster randomized, cross-over trial to investigate the effectiveness of (1) a 6-month aerobic exercise program, (2) a 6-month resistance exercise program, versus (3) a 6-month psychoeducation program on healthy lifestyle for improving frailty, physical performance, and quality of life in frail/prefrail older persons. After 6 months, participants receive the other two programs in a pseudo random order to explore any effects of program sequence.
- Detailed Description
This is a single-blind, cluster randomized, cross-over trial to investigate the effectiveness of (1) a 6-month aerobic exercise program led by trained young-old exercise coaches, (2) a 6-month resistance exercise program led by trained young-old exercise coaches, versus (3) a 6-month psychoeducation program on healthy lifestyle led by retired nurses for improving frailty, physical performance, and quality of life in frail/prefrail older persons. A total of 390 frail/prefrail older persons are randomized into one of the three programs in groups of 6 to 10 persons.
After 6 months, participants receive the other two programs in a pseudo random order to explore any effects of program sequence. The sequences are: (a) resistance exercise, aerobic exercise, psychoeducation; (b) aerobic exercise, resistance exercise, psychoeducation; and (c) psychoeducation, resistance exercise, aerobic exercise. The entire intervention period lasts for 18 months.
