Background and objectives: Episodic specific induction (ESI) is a manipulation shown to enhance episodic memory function. Episodic specificity induction involves thoroughly unpacking a recently encoded memory, with this enhanced retrieval-induced process helping to facilitate subsequent cognitions. In addition to ESI, emerging work suggests that acute exercise may also help to facilitate episodic memory function. The purpose of this study was to evaluate the potential individual and combined effects of acute exercise and ESI on subsequent episodic memory performance. Materials and Methods: Participants (n = 120) were randomly assigned into one of four groups, (1) ESI and exercise (ESI + E), (2) ESI only (ESI), (3) exercise only (E), and (4) no ESI and no exercise (Control; C). The ESI protocol involved watching a short video and then recalling details about the setting, people, and actions in the video. The exercise protocol involved an acute bout (15 min) of treadmill exercise. After these tasks, episodic memory function was evaluated with an autobiographical interview assessment and a computerized episodic memory task involving what–where–when integration. Results: We did not observe significant main effects for exercise or ESI on memory function but did observe some suggestive evidence of an interaction effect of these two parameters on episodic memory. That is, for the exercise group, memory performance was higher when combined with ESI as opposed to without ESI. Conclusions: Acute exercise and ESI may interact to influence episodic memory function. View Full-Text
