Fifteen minutes of exercise create optimal brain status to master new motor skills, a study found
The study found that exercise performed immediately after practicing a new motor skills improves its long-term retention.
research shows, that a minimum of fifteen minutes of cardiovascular exercise increases the connectivity and efficiency of the brain.
Leading author of the study, Marc Roig had previously demonstrated that exercise helps to consolidate muscle or motor memory. This time, they were trying to find out what was happening in the brain, the interaction between the mind and the muscles and what helped the body maintain its motor skills.
To find out, the research team asked the participants different tasks. The first, known as the "pinch task", is a bit like a muscular video game.
The task was chosen because it involved participants in motor learning to modulate the force with which they gripped the dynamometer. around the screen. This was then followed by fifteen minutes of exercise or rest.
Participants were then asked to repeat an abbreviated version of this task, called a manual task, at intervals of 30, 60, 90 minutes, after exercise or rest. the researchers evaluated their level of brain activity.
This task involved that participants simply enter the dynamometer for a few seconds, with a degree of strength similar to that used to reach some of the target rectangles in the pinch. task.
The researchers found that those who exercised were constantly able to repeat the "pinch task" linking different areas of the brain more efficiently and with less brain activity than those who had not done so. exercised
. The researchers found it intriguing that when they tested participants at the 8-hour mark, there was little difference between groups in retention of skills.
The complete results are published in the journal NeuroImage.
