On yer bike for a brain boost at work

Hop on an exercise bike for a cognitive recharge in between patients

A good way to recharge your brain at work might be with a short burst of exercise that doesn't require much concentration, according to a small study from Japan.

"The present study suggests that simple exercise is better than cognitively demanding exercise during working hours," said lead author Assistant Professor Keita Kamijo, from the faculty of sports sciences, Waseda University, Tokyo.

Professor Kamijo and co-author Ryuji Abe enrolled 28 men and had them perform tasks that challenged 'working memory'.

Working memory is what allows people to maintain and update information in their brains about things they're working on, such as assignments, goals and strategies.

The men took the working memory challenges before, immediately after, and 30 minutes after three different test periods on three different days.

The test periods were assigned in random order and lasted 25 minutes each.
