In a large study, German scientists have shown that physical fitness is associated with better brain structure and brain functioning in young adults.
This opens the possibility that increasing fitness levels may lead to improved cognitive ability, such as memory and problem solving, as well as improved structural changes in the brain. This work is presented for the first time at the ECNP Congress in Copenhagen, with simultaneous publication in the peer-reviewed journal Scientific Reports.
Scientists have previously shown that “exercise is good for the brain”, but most studies have not controlled for underlying causes which might give distorted results, such as body weight, blood glucose levels, education status, age and other factors, making it difficult to take an overall view of the benefits. In addition, studies have rarely looked at fitness in relations to both brain structure and mental functioning."
