Increasing exercise’s effect on mental health: Exercise intensity does matter

Suwabe et al. (1) composed a well-written and interesting study examining the relationship between mild exercise and hippocampal memory function. It is interesting that the neurobiological mechanisms responsible for the effects of exercise are systematically investigated. A prominent finding was that a short bout (10 min) of mild exercise increased activity, specifically in hippocampal subregions and in the entorhinal and parahippocampal cortices. This can be understood as a neurobiological mechanism that has contributed to exercise-induced cognitive benefits. We concur with Suwabe et al. (1), although we can identify one main problem in this study pointing to the intensity of exercise, which moderates the magnitude of the exercise-induced effect … [↵][1]1To whom correspondence should be addressed.
