Proven beneficial effect of physical activity on memory
Scientists have found that physical activity not only useful for the muscles of the body but also for the brain. For this, the researchers showed the participants .
Of the images evoked positive emotions, the other part — a negative, and some of the images were neutral.
Then the volunteers were put on a special simulator on the feet. From this experimental group required considerable physical effort, and the participants of the control group just sat in the chair, allowing the
machine and the experimenter to move his feet.
During the experiment, the scientists measured blood presure in the body and heart rate of the volunteers. Each of the participants also took a saliva sample to detect levels of neurotransmitters related to stres. 48 hours later, the volunteers returned to the lab. They now showed 180 photos — 90 images, which they have already seen, and plus 90 new. The control group remembered about 50% of the photos shown earlier, while the participants who engaged in a power simulator, — about 60%.
The study showed that is really simple to improve your memory with the help of strength training, and once again confirmed the positive impact of exercise. ” Even without an expensive fMRI scan can reveal which areas of the brain asociated with a similar effect. The results are consistent with papers that describe the parts of the brain, providing a positive effect of physical activity on human memory”, concluded the researcher Audrey Duarte.
