Mild Exercise for Three Months Improved Cognitive Function and Brain Efficiency in Older Adults, New Study

A new study led by investigators at the University of Tsukuba  and the University of California, Irvine  found that mild exercise over a three-month period can significantly improve cognitive function in healthy middle-aged and older adults. The greatest benefit was seen among older individuals, where the exercise regimen led to enhanced brain activity and efficiency in the prefrontal cortex. 
Previous studies have shown that even brief sessions of mild exercise, such as walking and yoga, can stimulate the brain and yield temporary improvements in cognitive performance. However, the impact of long-term mild aerobic exercise on&nbsp;brain function&nbsp;in humans, as well as the underlying mechanisms involved, has not been explored.
