解析
Parents whose children show a special interest in a sport feel very difficult to make a decision about their children’s careers.Should they allow their children to train to become top sportsmen and sportswomen? For many children it means starting schoolwork very young.And going out with friends and other interests have to take a second place.It’s very difficult to explain to a young child why he or she has to train five hours a day, even at the weekend, when most of his or her friends are playing.
Another problem is of course money, In many countries money for training is available from government for the very best young sportsmen and sportswomen.If this help can not be given, it means that it is the parents who have to find the time and the money to support their child’s development and sports clothes, transport to competitions, special equipment, etc.All can be expensive.
Many parents are worried that it is dangerous to start serious training in a sport at an early age.Some doctors agree that young muscles may be damaged by training before they are properly developed.Professional trainers, however, believe that it is only by training when young that you can reach the top as successful sports person.It is clear that very few people do reach the top, and both parents and children should be prepared for failure even after many years of training.
