Investigating the effects of indoor cycling on slowing Alzheimer's disease progression in older adults at genetic risk.

CYCLE-AD: Randomized Controlled Trial to Assess the Efficacy of Indoor Cycling in Slowing Disease Progression in Healthy Older Persons at Genetic Risk for Alzheimer’s Disease

NIH-funded research Cleveland Clinic Lerner Com-Cwru · NIH-11009531

This study is looking at how high-intensity indoor cycling might help protect the brain health of healthy older adults aged 65 to 80 who have a specific gene linked to Alzheimer's disease, by comparing their cognitive function and brain scans before and after the exercise program.

What this research studies

This research focuses on the impact of high-intensity indoor cycling on healthy older adults who carry the APOE ε4 allele, a significant genetic risk factor for Alzheimer's disease. Participants aged 65 to 80 will be randomly assigned to either a cycling group or a control group, with the cycling group engaging in home-based high-intensity interval training. The study aims to assess changes in cognitive function and brain imaging over time, providing insights into how physical activity may protect against cognitive decline. By monitoring participants' activity levels and health outcomes, the research seeks to establish a clear link between exercise and brain health in at-risk individuals.

Who could benefit from this research

Good fit: Ideal candidates for this research are healthy older adults aged 65 to 80 who carry the APOE ε4 allele and are currently sedentary.

Not a fit: Patients who are not genetically at risk for Alzheimer's disease or those who are already highly active may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a new, effective intervention to slow cognitive decline and delay the onset of Alzheimer's disease in genetically at-risk older adults.

How similar studies have performed: Previous research has indicated that physical activity can have protective effects against cognitive decline, suggesting that this approach may yield positive results.
