The result of experiments conducted on mice shows the growth of cells in the brain region called the dentate gyrus, hippocampus or the central part of the requirements. In humans, the dentate gyrus was strongly influenced by age, especially in terms of ability to remember a person who begins to decline when an 30-year-old.
"Previously there was no study that examines the systematic differences in brain regions in the hippocampus and determine where the affected parts of the brain sport," said Dr.Scott Small, a neurologist from Columbia University Medical Center, New York, USA.
After successfully seeing the process that occurs in mice, the researchers then conduct research on humans. Those involving 11-bodied volunteers who were asked to do aerobics daily for three months. The brains were photographed using MRI before and after doing this aerobic program. The research team also measured the ability of the body of each volunteer by measuring the volume of oxygen in their body before and after the exercise program.
Apparently based on the results of MRI, exercise blood circulation to the area dentate gyrus and the more fit a person, the more smoothly the flow of blood.
"However, further research we will do is determine what type of exercise most beneficial to improve memory and reduce senility. I hope someday the doctors could recommend that patients who begin to experience memory decline to exercise," said Small.
