<< Everybody must feel necessity of young children's doing sports activity to some extent. In general, doing sports is advantageous for children's sound growth. But if the time they spend on doing these activities is so long enough to occupy the most of their available times , there are both mirit and demerit. It is depending on each children�fs character that the experience at the club is advantageous or disadvantageous. When children have opportunities to do sports for a long time, in my country, Japan, they usually belong to local sports team. Therefore in this essay, I would like to analyze sports activities' long time occupation of children's time mentioning their activities at local sports club. Local sports activity will give children excellent chance to learn fairness and cooperative attitude toward the experience at the club. They are forced to control their own feeling from the experience of team play. At first they might complain about its harshness or feel that they have no freedom. However, gradually they will learn the necessary of cooperative attitude to win game. They will learn the importance of fairness through the sports activities during which they are under the certain rule of the sports. Long time they are devoted to play the sports make them learn these things efficiently. These things cannot be acquired in short term. By spending long time with other teammates, young children will find their life long friends. They always do the same things and aim to win the game. Having the same experience and goals to achieved, they will become good friends with one another. In fact, my young brother, starting to play soccor as a member of local sports club when he was seven years old has found lots of close friends at the football club. Friends will be treasure in their lives and therefore, the chance they can get from the experience in the club is very precious. Despite these merit of young children's playing at local sports club, disadvantageous thing is here, that is, long time sports activities bond children so much that they can hardly do other important things. They have few time to study. As for my brother, he went to school at seven in the morning to practice soccer and after school, he go back to home and eat supper, then he went to school again and until eight o'clock in the evening, he played soccer. Holiday did not mean the rest time for him because he used to have succor game on Sunday. I remember that at home he would be exhausted physically so that he took great pain to do homework. In this way, children are bond by long time sports activities tightly which can prevent them from spending enough time on studying. As I mentioned, thinking about the effect on children, spending long time on sports activities have both good and bad points. With the consideration of these merit and demerit, I would like to conclude that it is depending on the character of each young children whether or not long time sports activities are good or bad for the children. If only they can make the most of the limited time for doing other important things than doing sports, children should play sports in order to learn lots of things and make good friends with others.
