Pilot Study of the Effects of Exercise on Aging Among Older Persons With HIV

The exercise intervention has three components: (1) aerobic exercise with a metabolic equivalent of task (MET) energy expenditure of at least 900 MET-minutes per week; (2) strength training consisting of 2 sets of 4 upper body exercises (bench press, seated row, shoulder press, and pull down), 3 sets of 3 leg exercises (leg press, extension, and flexion) and 2 sets each of abdominal crunches and back extensions. Weights for each exercise will be gradually increased as participants can complete 12 repetitions for each set on 2 consecutive sessions, with participants performing strength training twice per week total. Three workshops on using ChiWalking or ChiRunning technique for achievement of aerobic activity goals will be provided to participants in the experimental arm.
