TL;DR
A University of Tsukuba study of 24 healthy young adults found that a 10-minute session of very slow jogging was followed by improved self-reported mood and Stroop test performance. The small study measured immediate effects; it does not establish long-term benefits or show that jogging should replace walking.
A study published in Imaging Neuroscience found that 10 minutes of very slow jogging was followed by improved mood and performance on a measure of attention among 24 healthy young adults. The University of Tsukuba researchers also detected changes in prefrontal-cortex activity, suggesting that gentle running may have immediate effects even when it is performed at low intensity.

Participants completed two 10-minute sessions: one sitting on a stationary treadmill and one running at roughly 3 to 6 kilometers per hour (about 1.9 to 3.7 miles per hour). The jogging intensity was about 35% of peak oxygen uptake among participants, according to the report. Researchers assessed mood and cognitive performance before and after each session and used functional near-infrared spectroscopy to measure activity in the prefrontal cortex.
After the jogging session, participants reported a more pleasant mood and performed better on a Stroop test, which assesses executive-function skills such as attention and handling conflicting information. Researchers recorded increased activity in prefrontal-cortex areas associated with executive function and mood regulation. Sitting for 10 minutes did not produce comparable changes. These were immediate results in a small group, not evidence about lasting effects or outcomes for all age groups.
The report describes slow jogging as running at a comfortable, conversational pace. The Japanese phrase “niko niko pace” means “smiling pace,” reflecting the idea that a person should be able to talk comfortably. Though it can look much like brisk walking, jogging includes a brief moment when both feet are off the ground. The article says walking remains beneficial and the study does not suggest replacing it.
A Short Session, Immediate Measures
The findings offer a possible option for people who find conventional running strenuous or difficult to fit into the day: a brief, low-intensity session was linked to changes on mood and attention measures immediately afterward. That could make the study relevant to people considering short movement breaks, including before a mentally demanding task. Study supervisor Hideaki Soya suggested that a brief, slow run might help before a presentation or similar task.
The evidence has clear limits. The study involved only 24 healthy young adults, and the reported changes were measured around a single 10-minute session. It does not show whether the effects persist, whether repeated sessions produce different outcomes, or whether the same results apply to older adults or people with health conditions. The results are a research finding, not a guarantee that jogging will improve any particular person’s mood or concentration.

How Slow Jogging Is Defined
Exercise physiologist Hiroaki Tanaka popularized slow jogging, according to the Seniors Guide report. Its defining idea is a pace gentle enough to keep conversation comfortable, rather than a target speed, distance, calorie count or competitive result. In the study described, participants jogged at a speed that can overlap with ordinary walking speeds, while using a running motion.
The researchers examined whether running’s movement pattern might matter in addition to exercise intensity. Running creates more rhythmic vertical movement of the body and head than walking. Sensors measured this head acceleration; participants with greater vertical movement tended to show larger mood improvements. The report also notes that previous research links physical activity, including walking, with better physical and mental health. The new study asks a narrower question about very slow running and immediate responses.
“A brief, slow run might help before a presentation or another mentally demanding task.”

Longer-Term Effects Remain Unknown
The study does not establish how long the reported mood and Stroop-test changes lasted, whether they occur after repeated jogging sessions, or whether they extend to people beyond the 24 healthy young adults who took part. The report does not provide a comparison with brisk walking, so it cannot show that jogging produces greater benefits than walking.
The possible role of the jogging motion is also unresolved. Greater vertical head movement was associated with larger mood improvements, but that association does not establish cause. The report says one proposed explanation comes from animal research suggesting that head acceleration may activate neurons involved with serotonin. That explanation remains theoretical in humans; the study does not prove that the bounce of jogging improves mood through this mechanism.
Further Research on Movement
Researchers plan to investigate the relationship between vertical head movement and mood further, according to the report. Further studies would need to clarify the mechanism and establish whether effects last beyond the immediate post-exercise measurements. Comparisons involving other forms and intensities of movement could also help show what, if anything, is distinctive about slow jogging.
For now, the report presents slow jogging as a possible gentle way to move, not a proven treatment or a replacement for walking. The next evidence to watch for is research that tests the result in larger and more varied groups and tracks outcomes over time.
Key Questions
What did the slow-jogging study find?
Among 24 healthy young adults, a 10-minute slow-jogging session was followed by more pleasant self-reported mood and better Stroop test performance. Researchers also detected changes in prefrontal-cortex activity.
How slow was the jogging?
Participants ran at about 3 to 6 kilometers per hour, or roughly 1.9 to 3.7 miles per hour. The report describes the pace as light enough to allow comfortable conversation.
Does the study show that jogging is better than walking?
No. The experiment compared jogging with sitting, not with walking. The report says walking remains beneficial and the study does not show that people should replace it with jogging.
Are the mood effects proven to last?
The report describes immediate changes measured around the session. It does not establish how long they last or what happens with regular slow jogging.
