Studies of the dose-response curve for exercise have typically shown that little exercise is much better than no exercise, and gains continue at a slowing pace up to a fair way above the recommendation of 150 minutes of moderate to vigorous physical activity per week. See research showing that two to four times that amount further improves outcomes, for example. At some point, however, diminishing returns tip over into harm. There is such as thing as too much physical activity, though few people reach that point. The study here, in which researchers generate a brain aging metric derived from neuroimaging data and correlate its progression with physical activity, is interesting for producing a dose-response curve that …
A Dose-Response Curve for Physical Activity and Slowed Brain Aging
