University of Tsukuba study finds slow running boosts brain function

A study conducted by the University of Tsukuba suggests that just 10 minutes of very slow running can significantly improve mood and executive brain functions. The research challenges the notion that running must be high-intensity to provide mental benefits.

Participants in the study performed a 10-minute treadmill session at approximately 35 percent of their VO2 max, a very light effort comparable to a brisk walk. Researchers used functional near-infrared spectroscopy (fNIRS) to monitor the prefrontal cortex. The results showed increased activity in brain regions responsible for emotion regulation and mental skills, specifically in the left dorsolateral prefrontal cortex and the left frontopolar cortex.

Following the light running session, participants demonstrated improved performance on the Stroop test, which measures executive function and attention control, and reported more positive moods compared to a resting control group.
