The broader purpose of this study was to examine the temporal effects of high‐intensity exercise on learning, short‐term and long‐term retrospective memory and prospective memory. Among a sample of 88 young adult participants, 22 were randomized into one of four different groups: exercise before learning, control group, exercise during learning, and exercise after learning. The retrospective assessments (learning, short‐term and long‐term memory) were assessed using the Rey Auditory Verbal Learning Test. Long‐term memory including a 20‐min and 24‐hr follow‐up assessment. Prospective memory was assessed using a time‐based procedure by having participants contact (via phone) the researchers at a follow‐up time period. The exercise stimulus included a 15‐min bout of progressive maximal exertion treadmill exercise. High‐intensity exercise prior to memory encoding (vs. exercise during memory encoding or consolidation) was effective in enhancing long‐term memory (for both 20‐min and 24‐h follow‐up assessments). We did not observe a differential temporal effect of high‐intensity exercise on short‐term memory (immediate post‐memory encoding), learning or prospective memory. The timing of high‐intensity exercise may play an important role in facilitating long‐term memory.
