A new study suggests that going on longer walks may have more health benefits than taking the same number of steps a day over multiple short walks.
Hundreds of studies have shown that higher step counts are tied to lower risk of dementia, Type 2 diabetes and other health issues. But how best to get those steps is less clear. The new analysis, published Monday in the Annals of Internal Medicine, is one of the first to study whether spacing steps out or consolidating them was linked to better health outcomes.
The analysis looked at people who took fewer than 8,000 steps per day; most participants took fewer than 5,000. Those who regularly walked longer than 15 minutes were 80 percent less likely to die from any cause and nearly 70 percent less likely to develop cardiovascular disease over a roughly 10-year period, compared with those who got most of their steps in walks of five minutes or less. (The average age of the participants was 62, so the risk of dying was fairly low to begin with: about 4 percent in the shorter-walks group and less than 1 percent in the longer-walks group.)
This data shows only a correlation; it does not prove that taking longer walks is healthier than spacing your steps out over the day. But some evidence suggests that your body needs more time and continuity to fully tap into exercise’s health benefits, such as improved heart rate regulation, said Dr. Robert Gerszten, the chief of cardiovascular medicine at Beth Israel Deaconess Medical Center who was not involved with the study.
