Exercise Training to Improve Brain Health in Older HIV+ Individuals

Summary

Management and treatment of older persons living with HIV (PLWH) (≥ 40 years old) is becoming increasingly more complex as a majority is greater than 40 years old. This proposal will conduct a prospective controlled intervention trial to assess the quantitative and qualitative effects of a monitored aerobic/resistance exercise (EXS) program compared to a social-interaction stretching (SIS) program on brain health (neuropsychological performance testing and neuroimaging measurements) in older PLWH. These results could influence public health policy by encouraging PLWH to adopt a more physically active lifestyle and stimulate the development of effective EXS programs for older PLWH.

Interventions

BEHAVIORAL

Exercise

The resistance exercise training component will follow aerobic exercise and will consist of 4 upper and 3 lower body routines. A combination of guided-motion machines and free weights will be used. Voluntary maximum strength will be measured during the first 4 sessions on each exercise station. The program will initially consist of 1-2 sets of each exercise while lifting a weight that causes muscle fatigue after 8-10 repetitions. The trainer will monitor each participant's exercise response, and when the participant can comfortably lift the weight for 12 repetitions on any exercise, the weight will be increased to cause the muscle group to fatigue after 8 repetitions. This progressive 8-12 repetition cycle is repeated for each exercise over 26 weeks.

BEHAVIORAL

Stretching and Social Interaction

Participants will receive instructions on stretching, range of motion, limbering, and toning. Activities will focus on flexibility enhancement. Along with the stretching and flexibility, this group will have a social interaction component. They will have discussions and interact with trainers and coordinators during all their sessions. These participants will be supervised by the same trainer and will receive the same amount of attention and class interaction as participants in the EXS program.
