In this study, we tested the effect of acute exercise on long-term memory, specifically the timing of exercise relative to the memory challenge. We assessed memory via paragraph recall, in which participants listened to two paragraphs (exposure) and recounted them following a 35-min delay. Participants (n = 48) were randomly assigned to one of three groups: exercise prior to exposure, exercise after exposure, or no-exercise. Exercise consisted of 30 min on a cycle ergometer, including 20 min at moderate intensity. Only the exercise-prior group recalled significantly more than the control group (p less than 0.05). Differences among the exercise groups failed to reach significance (p = 0.09). Results indicated that acute exercise positively influenced recall and that exercise timing relative to memory task may have an impact on this effect. (Contains 4 figures.)
