In fact, many studies show aerobic exercise like running can improve memory. However, this study is different, because it includes weight training. The participants do weight training every other day before the test performed experiment.
"Even without doing MRI scans are expensive, our results give an idea about which brain regions that support that exercise is beneficial for memory," said Audrey Duarte, a professor at the Georgia Institute of Technology, Faculty of Psychology, United States.
For the purposes of the study, the researchers showed 90 participants through the photos on the computer screen before they start doing stretching exercises -dimulai of feet.
The researchers then asked the participants returned to the laboratory 48 hours later, to see as many as 180 photos. Photo 90 of them are photos that have previously been shown, while the rest of the new photos.
The results showed that those who exercise can remember about 60 photos.
"Our study shows, people do not need to dedicate a lot of time to improve memory of their brain," says study leader from Georgia Tech, Lisa Weinberg.
He noted, although these studies use weight training as a part, but light exercise such as bend-bent knees will likely produce the same results.
"These findings are encouraging, because it is consistent with the literature that shows part of the brain that plays a role in memory caused by sports," Weinberg said, as quoted by the Indian Express.
