The benefit of weight lifting from building muscle and even relieving psychological tension is known to most players of the sport, but what is new and surprising to some that weightlifting sessions have a direct impact on the work of the brain and during a relatively short period of exercise.
A new study of its kind on the brain and muscles suggests that exercise for 20 minutes strengthens and improves the memory of the players by 10%.
"This study suggests that a person does not need to play long hours until there is a positive effect on memory improvement," said study leader Lisa Weinberg, a graduate student at the Georgia Institute of Technology.
In the study, the researchers put 90 images on the computer screen on 46 volunteers and asked them to save these images in their memory, and then divided the volunteers into two groups.
The first group was asked to perform a certain exercise while the other group sat without any effort.
The researchers also collected saliva samples from each volunteer.
What did researchers find?
Volunteers who did exercise had 60% of the total, while the other volunteers remembered about 50% of the total.
This finding is supported by a previous study that says that adults between the ages of 50 to 85 improve their memory once they do some exercise and this is the result of the secretion of the body to the hormone
It was found in this study that exercise actually increases the presence of this hormone, for those who have exercise shows the presence of this hormone in the saliva at a high rate when they examined.
"These findings are encouraging. Without a costly magnetic resonance imaging test, we can predict which areas of the brain have the greatest effect on memory retrieval through exercise," said Professor Audrey Duarte, a professor of psychology at the same institute.
