The US Open Tennis Tournament was just over a week or so ago. Serena Williams was dominant in taking the women’s title again. She is certainly one of the most dominant figures in tennis today, and for that matter, in the history of the game. If you think about the older tennis champions, they were all smaller in build than the modern player. Most of today’s ladies are on the upper range of height and build, and they hit the ball with tremendous force. Gone are the days of volley tennis and here to stay seems to be power tennis.The men’s game is the same. There are 2 or 3 men on the pro tour who are 6’7″ or taller. They hit the ball at a speed of nearly 150 miles per hour. You just thought Aroldis Chapman could throw the baseball hard, but his speed is slow compared to these serves. Also, think of the court coverage that these tall men have over someone like Arthur Ashe.When you think about it, this is the same trend that is taking place in all phases of human development. Most people are bigger and stronger today. If you don’t believe so, go to the historical museums in Washington, D.C., and check the size of the beds that our forefathers slept in. Tennis player Eisner would need 2 of these beds put end-to-end so he could lay down in them.
