Japanese scientists from Tohoku University and other scientific institutions have discovered the physiological mechanism of the positive effect of physical activity on human mental abilities. The study was published in the scientific journal magazine Journal of Physiology (TJP).
According to previous research, even moderately intense exercise can improve a person’s ability to solve cognitive problems and sharpen their reactions. However, until recently it was unclear what processes caused this effect.
In the new study, scientists focused on dopamine, an important hormone associated with feelings of happiness and satisfaction. It is known that exercise releases dopamine in the brain. Experts have suggested that improved mental performance may be due to the release of this neurotransmitter.
The team conducted two experiments. The first required participants to go through an intense 40-minute training session and then complete a cognitive speed task.
In the second test, participants underwent electrical muscle stimulation that simulated physical activity. After this, the volunteers also completed a mental reaction task.
The results showed that full-fledged physical training releases dopamine and improves a person’s cognitive abilities, while artificial tension in peripheral muscles does not release the hormone and does not help people think faster.
Scientists concluded that dopamine is not only associated with pleasure and reward, but also plays a critical role in cognitive functions, especially in improving reaction time.
