In this study, the effect of acute and chronic exercise on long-term spatial memory was evaluated. It was found that exercise can improve long-term memory retention for short distances, but not for long distances. Additionally, individuals who engage in regular physical activity showed better memory for short distances compared to those who did not.
Physical activity benefits both fitness and cognition. However, its effect on long-term memory is unclear. In this study, we evaluated the effect of acute and chronic exercise on long-term spatial memory for a new virtual reality task. Par-ticipants were immersed in the virtual environment and navigated a wide arena that included target objects. We assessed spatial memory in two conditions (en-coded targets separated by a short or long distance) and found that 25 min of cycling after encoding - but not before retrieval - was sufficient to improve the long-term memory retention for the short, but not for the long distance. Furthermore, we found that participants who engaged in regular physical activity showed memory for the short-distance condition whereas controls did not. Thus, physical activity could be a simple way to improve spatial memories.
