British Journal of Sports Medicine have done some data analysing of study evidence and the result suggests that short bursts of moderate intense exercise boosts higher brain function, such as memory, concentration, planning, and decision-making in three age groups.
In short; exercise makes you smarter.
24 studies with three age groups have been investigated to find the effect of short burst exercising. 19 of these were relevant and they involved 586 participants.
The data concluded that all age groups showed a small to moderate increase in higher brain function after a short burst of exercise.
This also suggests that exercise can be used as a treatment for conditions characterised by impaired higher brain functions, such as ADHD and autism.
They speculate that short bursts of exercise may boost the cerebral blood flow to the pre-frontal areas of the brain, responsible for higher functions.
Now do some push-ups and exercise your brain at the same time.
