Brief Slow Jog Boosts Mood and Focus, Small Japanese Study Finds

In a small experiment, 24 healthy young adults completed a ten-minute slow treadmill run at speeds between 1.9 and 3.7 mph, followed by a separate resting session. Post-run testing revealed faster responses on attention and self-control tasks and higher self-reported alertness and pleasantness compared with the rest condition. Functional imaging indicated heightened activation in prefrontal regions linked to decision-making.

Average heart rates during the jog were 105-107 beats per minute, and the mood benefits remained after heart rates normalized. Researchers caution that the sample size is limited and results may not extend to older adults or those with health issues. Experts suggest a brief, easy jog could provide a temporary mental lift but is not a substitute for professional care.
