The Impact of Structured Exercise on Brain Health in HIV Positive Individuals


Brief description of study

Exercise programs that combine resistance exercise with aerobic training yield optimal health benefits for people with HIV. The global aim of this study is to contribute evidence for the impact potential of a comprehensive exercise program on brain health in people with HIV.

This study is part of a larger project based upon a cohort multiple randomized controlled design. Within a fully characterized cohort which is followed over time, people meeting the specific criteria for an exercise intervention will be identified. The sample will be randomly selected to receive the intervention; the remaining eligible persons will serve as controls. The intervention group will receive a 45 minute structured exercise program 3 times a week consisting of aerobic exercise and resistance training for a total of 12 weeks.

Detailed Study Description

Exercise is an inexpensive intervention with widespread benefits to vascular and musculoskeletal health and few harms. Showing an additional benefit to brain health and cognition in particular is likely to encourage adoption and help elucidate mechanisms underpinning brain health in HIV.

The primary objective of the study is to estimate, in comparison to individuals not offered the exercise intervention, the extent to which a comprehensive exercise program impacts on indicators of brain health, where these indicators are the primary outcome of cognitive ability (B-CAM) and the related brain health outcomes of depression, anxiety, fatigue, motivation, and speed of motor performance.

A secondary objective is to estimate the extent to which changes in brain health are mediated through exercise induced changes in brain network function as measured by EEG and/or by exercise induced changes in muscle power, aerobic capacity, physical function, and body composition.
