Physical Activity Helps Your Brain

A small randomized controlled trial, with 60 participants, adds to the evidence that physical activity, even in small amounts, is good for you. In this study, just published in The International Journal of Clinical Practice, participants were 70 years old and sedentary. Half the participants did an interval aerobic program for 30-minutes, twice a week, and the other half of the group continued to spend nine and a half weeks being sedentary.
