Children in Sport
The team manager of the English Lawn Tennis Association was interviewed about children who are trying to be champions in the world of sport and the pressures they can be under to win. This is what he said: "The problem is that you want to find these children at quite a young age, to train them and motivate them as early as possible. At that age they don't have social problems, so they can lose their sport the whole of their life. But they are so young thet they can lose their childhood, and they're adults before they are 16. But of course they are not adults at all. Physically they can be quite developed, but emotionally they're still children. Everybody's looking for the new young star of the future, because there's a lot of money to be earned.
Tennis is one of the sports where youngsters can play against their elders with more than a chance of success. There are tennis schools which accept children from as young as 9. So from the age of 9 a boy or girl is playing tennis for four or five hours every day, and doing ordinary school work around that. So they are already showing the pressures on their bodies and their minds, and people are beginning to question whether this is a good thing for children. A 14-year-old just can't cope with the pressures of Wimbledon, the tournament, the Wimbledon crowds, and the press reporters, I think young players shouldn't be allowed to become professionals until the age of 17 or 18 at least.
What was responsible for the pressures on the young players - it was the money that can be earned, the parents of the children themselves? It's the parents, without a shadow of a doubt. They want to push children. My advice to youngsters: stay at home, stay at school do the thing that teenagers like doing. If you like swimming, well swim; if you like going to disco, just go!
If you start getting upset every time you lose, I think it's time to stop.
