Animal models indicate that exercise promotes visual cortex neuroplasticity; however, results from studies have explored this effect in humans are mixed. A potential explanation for these discrepant is the relative timing of and task used to index neuroplasticity. We hypothesized a close temporal pairing training on vision would enhance perceptual learning (a measure neuroplasticity) compared non control. Thirty-two participants (mean age = 31 years; range, 20-65; SD 11.1; 50:50 sex ratio) were randomly assigned Exercise or Non groups. The group alternated between moderate cycling along virtual course peripheral crowding (5 minutes each, 1 hour total intervention), passive viewing task. protocol was repeated across 5 consecutive days. Both groups exhibited reduced after days training. However, there no difference magnitude rate Translation animal neuroplasticity may depend range factors, such as baseline fitness levels measures quantify
