What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology.

Summary: Longer duration of exercise, and not higher total extent of activity, shows the most promise for improved cognitive performance over longer periods of time.

A healthy body is home to a healthy mind: sporting activity can improve your cognitive performance. However, there are numerous different types of sports and a wide range of exercise and training. Which type and how much exercise will keep your mind in top shape? This is the question that has been explored by researchers at the University of Basel and their colleagues at the University of Tsukuba in Japan through a large-scale analysis of the scientific literature. They have used this analysis to derive recommendations that they recently published in the journal Nature Human Behaviour.
Coordinated sports are particularly effective
The research group with the participation of Dr. Sebastian Ludyga and Professor Uwe Pühse evaluated 80 individual studies to identify a few key characteristics. Endurance training, strength training or a mix of these components seem to improve cognitive performance. However, coordinated and challenging sports that require complex movement patterns and interaction with fellow players are significantly more effective. “To coordinate during a sport seems to be even more important than the total volume of sporting activity,” explains Ludyga.
A higher total extent of activity does not necessarily lead to a correspondingly higher level of effectiveness for mental fitness. Longer duration per exercise unit promises a greater improvement of cognitive performance only over a longer period of time.
All age groups benefit
Just like our physical condition, cognitive performance changes over the course of our lives. There is great for potential for improvement during childhood (cognitive development phase) and during old age (cognitive degradation phase). However, the research group of the Department of Sport, Exercise and Health (DSBG) at the University of Basel was unable to find an indicator of different levels of effectiveness of sporting activities within the varying age groups.
Furthermore, sporting activities from primary school age to later age do not have to be fundamentally different in order to improve cognitive performance. Different age groups can thus be combined for a common goal during sports. “This is already being implemented selectively with joint exercise programs for children and their grandparents,” says Pühse. Such programs could thus be further expanded.
Intense sports sessions for boys and men
The same volume of sports activity has a different effect on physical fitness for men and women, as we are already aware. However, the research group has now been able to verify this for mental fitness. Men accordingly benefit more from sporting activity.
Differences between the sexes are particularly evident in the intensity of movement, but not in the type of sport. A hard workout seems to be particularly worthwhile for boys and men. Paired with a gradual increase in intensity, this leads to a significantly greater improvement in cognitive performance over a longer period of time.
In contrast, the positive effect on women and girls disappears if the intensity is increased too quickly. The results of the research suggest that they should choose low to medium intensity sporting activities if they want to increase their cognitive fitness.

Systematic review and meta-analysis investigating moderators of long-term effects of exercise on cognition in healthy individuals
As cognitive function is linked with academic achievement, career success and mental health, there is a need to understand how the cognitive benefits of long-term exercise can be optimized. Our meta-regression included 80 randomized controlled trials and examined moderators of the effects of exercise on cognition in healthy individuals. The summary effect was small and did not differ between cognitive domains. Higher benefits of exercise on cognitive function were found after coordinative exercise compared with other exercise types. With longer intervention length, the effect size increased with longer session duration. Exercise was less effective in female compared with male individuals, and the dose–response relationship differed between sexes. Our findings suggest a general rather than domain-specific effect of exercise on cognition, which is influenced by sex, exercise type and reciprocal relationships between dose parameters. We derive sex-specific recommendations on how cognitive benefits can be optimized by exercise intensity, its progression and exercise type.
