Quick brain game may boost exercise in heart rehab

This study tested whether a short, 15-minute brain-training task (evaluative conditioning) could help heart attack survivors exercise at a higher intensity during cardiac rehab. Twenty-four patients were split into two groups: one received training linking physical activity with positive images, and the other received training about diet. The researchers measured the intensity patients chose on a stationary bike. The goal was to see if this simple mental exercise could encourage more vigorous activity, potentially improving heart recovery.
