The other surprising benefit of exercise

Since a long time, scientists believed that exercise not only gives more strength to the muscles but also the brain. One of them is to improve long-term memory that can keep you from all the forgotten disease.

Interestingly, recently a study published in the journal Current Biology, shows the other benefits of exercise.

Although you only do light exercise such as running a leisurely on a treadmill while watching television, such activities can improve the brain's visual ability.

"The visual cortex, a part in which the brain receives and processes visual information from the eyes, previously considered a part that does not have a role in changing one's visual ability in adulthood. But in fact, physical activity may improve the visual cortex to strengthen eyesight. This is very important and surprising, "said Dr. Claudia LUNGHI, a neuroscientist at the University of Pisa Italy who is the study's lead author, told The Huffington Post.

To obtain these conclusions, LUNGHI and his co-author Dr. Alessandro Sale, a scientist at the National Research Council's Neuroscience Institute in Italy, measuring the ability of the visual cortex in 20 adults.

During the study, participants were asked to watch a movie while relaxing on the couch. After that, they were then asked to watch a movie while working out on a stationary bike within 10 minutes.

The result, the researchers found differences in visual strength participants. After the exercise, the ability of the visual cortex increased, so that the vision becomes clearer.

The researchers noted that this effect may occur because exercise may cause a decrease in the concentration of inhibitory neurotransmitter in the brain called GABA, which means when the neurotransmitter concentration falls, the visual capabilities will increase.

Lunghi said, although this effect only lasts about 1 hour after exercise, regular physical exercise can increase the brain's visual ability in the long term.

The researchers concluded, the sport will very likely play an important role in eye care, such as amblyopia, known as "lazy eye".

The researchers plan to test the effects of exercise on adult amblyopia patients in future studies. And other scientists agree that more research is needed.
