According to research, about 21.5 million American children between the ages of six and seventeen are involved (参与的) in a team sport. But regardless of the reasons for getting involved, children can gain a lot from sports.
A 2006 report shows that taking up sports can increase both emotional and behavioral well-being in teenagers. And increased well-being can lead to higher confidence, which results in better overall performance. In addition, they usually get along well with people around them and are less likely to have bad or risky behavior.
Through this process, children develop social and leadership skills and learn the value of teamwork. Children involved in sports usually have stronger and better relationships with their schoolmates and a better understanding of people from different backgrounds.
Actually, sports give children an opportunity to communicate with adults in valuable and positive ways, which can help them develop closer relationships with adults. This effect is especially great when children don't get along well with their family members.
Although most effects of sports on children are good, there can be disadvantages. If the pressure to win is overemphasized (过分强调) or the expectations of parents or coaches become too great, kids may experience lots of stress. To avoid these bad effects, children should not overemphasize winning but focus on developing certain skills.
