Key Points

The central aim was to investigate the influence of acute exercise on the process of directed forgetting.
Examined participants' emotional memory recall.
Utilized tasks targeting memory modulation.
Monitored the activation of the dorsolateral prefrontal cortex.
Acute exercise significantly improved directed forgetting.
Participants recalled fewer negative emotional memories after exercise.
Activation of the prefrontal cortex correlated with improved memory modulation.

Abstract

Introduction Stress-related disorders, such as depression, are linked to a bias for remembering negative events (memory bias). Directed forgetting involving the prefrontal cortex can intentionally reduce these memories, and studies suggest that exercise enhances this process by activating the dorsolateral prefrontal cortex. Therefore, the study aim was to examine the effects of acute exercise on directed forgetting.
