This clinical trial evaluates the impact of a research intervention of virtually supervised exercise program (RISE) on cancer-related cognitive impairment (CRCI), physical activity in adolescent and young adult (AYA) brain tumor survivors. This clinical trial also evaluates the impact of RISE on the collection of microorganisms that exist in the intestines (gut microbiome). Up to 45% of AYA brain tumor survivors experience CRCI, including issues with attention and memory. CRCI can have a negative impact on education, independent living and can worsen long-term quality of life. Moderate-intensity levels of exercise, particularly aerobic and resistance training, have been shown to improve cognitive function. Additionally, exercise can change the composition and function of the gut microbiome, which may lead to improved cognitive function. Unfortunately, only about 50% of AYAs with cancer receive exercise information or meet the physical activity recommendations. Tailoring a virtually delivered exercise intervention to meet the unique needs of AYAs may improve access to exercise. Participating in the virtual home-based exercise intervention, RISE, may improve physical activity and cognitive impairment in AYA brain tumor survivors and may also help researchers understand the relationship of exercise on the gut microbiome and cognitive function.
