A cluster-randomized controlled trial was conducted to test the effects of a six-month VA program on the muscle mass, muscle strength, and quality of sleep of institutional older adults with sarcopenia. Using convenience sampling, 12 long-term care facilities with 114 older adults were recruited, and then cluster-randomized by the facility to a VA experimental or a control group. The experimental group received the VA program led by certified instructors 3 times per week and 40 minutes per session for 6 months; the control group continued with their regular daily activities. One pre-test and two post-tests, 3 months apart, were conducted.
