| Sumario: | Objective: In this study, we evaluated whether exercise prior to memory encoding or during memory consolidation can influence episodic memory function after being exposed to a stressful environment. Methods: We conducted 3 between-group randomized controlled experiments among young adults. We assessed episodic memory (via logic memory task) at the beginning of the experiment and approximately 45 minutes later. Across the 3 experiments, we varied the temporal period (eg, before memory encoding or during consolidation) of the acute bout of exercise (15-minute moderate-intensity exercise) and psychological stress induction. Results: Across all 3 experiments there was a statistically significant main effect for time for memory function, but there were no time x group interaction effects. Conclusion: Memory declined across the 2 assessment periods, but for all 3 experiments, exercise was not associated with memory function after being exposed to a stressful stimulus.
