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.
