Plain and simple. If you could see how you get a tennis ball at 200 kilometers per hour, would be lucky if we simply got them dodge. But mejoes players manages to return the ball. It gives them time to turn the racket and the ball back after seeing where the ball will go. And all this in half a second. Swiss experts have concluded that those skilled in tennis, like his Roger Federer, have better visual quality, while scientists in Britain have shown how animals (and presumably humans), can improve their internal models of motion to predict the path that will to make objects at high speeds. Athletes have to learn three levels of response: 1. First, the basic reaction, also known as optometric reaction, which is to detect the object and out of his way. 2. Then comes the perceptual reaction, which is to identify the object that comes to you (ie, knowing that it is a tennis ball and not a firebird). 3. And finally, the reaction cognitive , knowing that the object comes to you and you have a plan ready to see what you do with it. The latter was achieved with much training, but first elite tennis players have to be experts in the first two. Not only are visual experts also have to train hard every day to achieve to have the best response capabilities. Source | LiveScience
