One-minute exercise breaks at work and mental performance
A randomized pilot study of 25 sedentary middle-aged office workers found better results on attention and mental flexibility tests after four weeks of short bursts of vigorous exercise.

What the research shows
Researchers at the University of Hildesheim in Germany randomly assigned 25 bank employees, with an average age of 51, to two groups. Twelve ran on the spot for one minute, three times a day, four days a week, for four weeks. The other 13 kept their routine. Performance was measured with the Trail Making Test and the Stroop test, which assess processing speed, working memory and impulse control.
The exercise group improved on the tests right after the first break and again at the end of the four weeks, while the control group stayed about the same. The differences were statistically significant on every test.
What it means
The study suggests that short active breaks during the workday may help the thinking of people who sit all day, without a gym or much time. This fits earlier research linking intense exercise to better cognitive function.
How to read it with care
This is a pilot study with few people, mostly women, and the test right after the first break had no comparison group. The authors themselves call for larger studies before firm conclusions.
