Summary
Brief summary (as posted)
Understanding the impact exercise has on a cancer survivor's gut microbiome can improve the health and well-being of cancer survivors by enhancing treatments targeting the gut microbiome. Although scientific studies support a link between exercise and the gut microbiome, rigorous randomized trials needed to confirm this causal link are limited and usually involve supervised exercise. Hence, this proposal tests feasibility of a home-based, remote-only research protocol that is more accessible to cancer survivors unable to attend supervised exercise including but not limited to rural populations. This study will also determine if exercise effects on the gut microbiome differ by factors such as race.

- label
- Home-based aerobic exercise training
- description
- home-based aerobic exercise condition will receive a fitness bracelet (with heart rate measurement capability) and weekly exercise counseling from an exercise trainer (i.e., exercise physiologist) by videoconference. The weekly counseling will be guided by the fitness bracelet data (both participant and exercise trainer will share the same log in information). The aerobic exercise progression will gradually increase duration and intensity of aerobic exercise with the goal of improving cardiorespiratory fitness.
