Abstract

Objective: The objective of this experiment was to evaluate the role of acute exercise timing on true and false memory performance. Methods: A randomized controlled, within-subject design, was employed (N=39). The five counterbalanced visits included a control visit, vigorous-intensity exercise (80% of HHR; heart rate reserve) before encoding, vigorous exercise during encoding with no delay before encoding, vigorous exercise during encoding with a delay before encoding, and light-intensity exercise (30% of HHR) during encoding. A recognition task using the DRM (Deese-Roediger-McDermott) paradigm was used to evaluate true and false memory performance. Results: With hit rate as the outcome, there was a significant main effect for condition, F(4, 152) = 7.89, p < .001, η2 = .12. Similarly, with the lure false alarm rate as the outcome, there was a main effect for condition, F (4, 152) = 2.937, p = .02, η2 = .04. Ultimately, vigorous-intensity acute exercise during encoding reduced both true and false memory performance (p < .05). Conclusions: This experiment demonstrates that the timing and intensity of acute exercise play an important role in influencing memory performance.
