Engaging in just 10 minutes of slow-paced exercise can significantly improve brain function and mood, according to research published in the journal Imaging Neuroscience. The study suggests that even low-intensity physical activity can yield notable cognitive and emotional benefits.
Researchers observed 24 healthy participants performing a slow-paced treadmill session, akin to walking at two to four miles per hour. Within this short timeframe, participants reported an improved mood and demonstrated shorter Stroop interference times. This indicates enhanced cognitive control, faster information processing, and more efficient cognitive inhibition.
The study also noted increased activity in the prefrontal regions of the brain, areas crucial for executive functions and mood regulation. This neural activity is linked to the gentle up-and-down motion of the head during exercise, a movement previously studied in mice and associated with mood enhancement and the brain's self-cleaning process, known as the glymphatic system. This system is vital for clearing harmful proteins that can accumulate and lead to inflammation and neuronal damage.
The findings suggest that slower running paces and shorter exercise intervals could be particularly beneficial for individuals with lower fitness levels or those who find traditional exercise routines challenging.
Previous research supports the notion that brief periods of light exercise can positively impact cognition. A 2021 study from the University of Tsukuba found that 10 minutes of moderately intense running was sufficient for a cognitive boost. Additionally, research from 2018 indicated that 10 minutes of very light intensity exercise, including yoga, tai chi, or a slow walk, enhanced the hippocampus, a brain region essential for memory formation.
These studies collectively suggest that even short durations of light-intensity exercise can have a positive and measurable effect on cognitive function. The researchers behind the recent study emphasize that starting with low-intensity exercise may offer greater benefits, as more extreme physical efforts can sometimes have detrimental effects on the brain.
