Sci Rep's new discovery! There is a strong correlation between physical activity or brain memory performance!

September 27, 2020 // -- In a recent study published in the international journal Scientific Reports entitled "Effect of acute physical exercise on motor sequence memory", scientists from institutions such as the University of Geneva in Switzerland found that exercise and brain memory may be closely related.
If exercise is good for the body's health, it seems to be good for brain health, and by assessing the body's memory performance after exercise, the researchers found that even a shorter than 15 minutes of intensive exercise on a bicycle can help improve the brain's memory, including gaining new motor skills. The researchers found that this may have been achieved by increasing the plasticity of synapses through a molecule called endocannabinoids, which highlights the importance of exercise for the health and education of the body, and aims to reduce the effects of neurodegeneration on the body's memory through educational programs and strategies.
Many times, after exercise (especially endurance sports, such as running or cycling), we feel physical and psychological relaxation, which is caused by endogenetic cannabinin produced by the body during physical exertion, which circulates through the body and easily crosses the blood-brain barrier, then binds to special cell receptors and induces excitement in the body, in addition, the same molecules can also bind to receptors on the body, so what is the connection between movement and memory?" This may be what researchers need to focus on.

Previous studies, researchers have found that exercise has a positive effect on a memory style called associated memory, but contrary to the results of this paper, the researchers observed that moderate-intensity exercise classes have better results, which may indicate that not all forms of memory use the same brain mechanisms, and not all exercise intensity produces the same effect, and it should be noted that in all cases physical activity improves the brain's memory better than not exercising.
By providing accurate neuroscience data, research may help researchers develop new strategies to improve or preserve brain memory, and is physical activity an easy-to-implement, less traumatic and inexpensive intervention, such as scheduling a physical activity at the end of a school morning class, to help strengthen brain memory and improve learning? Previously, researchers are studying brain memory disorders in depth, especially in people at high risk of Alzheimer's disease, some of whom may experience subtle memory defects at age 25, the activation of the brain's sea mass, so researchers want to use the study to assess the extent to which physical activity can help compensate for early defects as a precursor to Alzheimer's disease.
