The position of the navel in the human body shows whether the person can have better performance in running, swimming or other sports, ... according to research published in the journal International Journal of Design and Nature and Ecodynamics.
Scientists from Duke University and Howard (Washington) in the US analyzed data almost young & battaglia 100 years regarding track and field athletes who competed in the sport of speed race of 100 meters and a swimming athletes who competed in the respective sport pool. They took into account only the geographical origin of the athletes and some biological criteria (eg body composition) rather than racial criteria. Carefully examined those factors in the body of athletes or other features that made them successful in their sport. They found that the position of the navel in the human body plays an important role in a person's performance young & battaglia in any sport. The navel is the center of gravity of the body. If two sprinters have the same height, then he has an advantage that the navel is higher. Leaning forward to run, athletes throw their center of gravity and momentum to get their traffic from it. As you know, the weight is higher and creates greater young & battaglia momentum. Similarly, swimmers, he displaces more water in motion is an advantage. In this case the athlete having lower navel also receive this advantage because it has a larger trunk and displaces more water. Specifically, the researchers found that athletes from West Africa have their navel on average 3 cm higher than their European competitors. Thus, African athletes have an advantage as sprinters and Europeans have an advantage as swimmers. Also, athletes from countries of Asia have their navel in approximately the same location as the Europeans and could have the same advantage in swimming with the Europeans, but is generally shorter than them.
