Can a quick bike ride boost brain power? new study investigates
NCT ID NCT06950060
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study looks at how short bursts of aerobic exercise affect brain function in older adults and stroke survivors. Researchers will compare three groups: one doing moderate cycling to raise lactate levels, one doing light cycling, and one receiving health education only. Participants will complete learning tasks and brain tests to see if exercise helps improve movement and memory. The goal is to find simple, low-cost ways to support brain health as we age or recover from a stroke.
