Study links walking to better mental performance

A study published on October 11, 2026, in Scientific Reports suggests that daily walking is associated with improved mental performance. Researchers found that higher levels of walking correlated with better scores in attention, cognitive control, and self-control among participants.

Participants wore Fitbit trackers for 14 years

The research analyzed the steps of 3,093 Americans recorded by Fitbit bracelets between 2009 and 2023. Those who walked 1,000 more steps per day showed better results in attention and cognitive control tests, with a 0.31-point increase in attention scores on average.

Tests evaluated mental abilities and self-control

The study participants, aged 18 to 93, were part of the national All of Us program. They took computer-based tests assessing sustained attention, distraction resistance, and facial emotion recognition. A final test required choosing between a small immediate reward and a larger, delayed one to measure self-control.

Walking may help prevent cognitive decline

Mild cognitive impairments could affect 21.55 million people in the United States by 2060, up from 14.37 million in 2025. The study used objective step counts over a long period, unlike many previous studies that relied on self-reported physical activity. However, the findings show statistical associations, not proven cause-and-effect relationships.
