Why age-related macular degeneration occurs is not clear, but the risk of developing the disease increases the older you get, and it is more common in women than in men. The macula is the area in the middle of the retina where we see as the sharpest. As you get older can change the macula, which means that you can get hard to see and above all to see sharply. Test if you have visual difficulties associated with the macula here. Read the rest of this entry »

Run barefoot more beneficial for the body because of our feet on the ground directly. Also, runners who bare feet lower risk of injury because of anatomical foot when setting foot better.

The researchers observed that when people run with variations, runners who do not wear footwear tend to use the entire leg or as part of setting foot hits the ground first is the soles, new heels.

In contrast with the runners who wore shoes, 75 percent landed their heels first. This method is more risk of injury.
“Landed feet by the middle or front of your foot is needed first leg and calf muscles are strong, but shocks to the smaller muscles”.

Human foot evolved specifically and have anatomical characteristics as walking barefoot. This occurred approximately 4-6 million years ago. “However, approximately 2 million years ago humans began to tiptoe due to start running”.

Those who ran barefoot tend to avoid landing the heel first, since if done repeatedly can make your feet hurt. While shoes offer comfort, so they no longer land a part of his front leg.

Then, if we have to start taking off shoes? Not really was. However, the researchers suggest that we are slowly starting to learn to land the center of the soles of the feet while running.

Outside the footwear issues, many of the benefits we can gain from running activities. Among others to train the cardiovascular system or blood flow throughout the blood vessels, including the heart. And certainly, running is an activity that effective to burn fat.
