Sport is a beneficial subject for children in primary and secondary school. Some sports at school are running, swimming or long jump and most of them are not so competitive. Some people think that competitive sports are no need in the school 's programme. However, in my opinion, they are vital for children’s development.

It also prevent people from risk of obesity and heart attack. Furthermore, sport make their brain more active. As a result, people could study or work better. In children, sports are essential for the development of physical and mental health. Sports bring benefits in strength, height and stature for children. For all of these advantages, sports should be taught at school. However, competitive sport take a more important role in children education. There is so boring and not exciting for running or swimming alone. Consequently, when children compete with their friends, they are motivated to try more. Besides, sports also increase their communication. When children take part in some competitive sports like football, volleyball or basketball, they have to build up a team work. As a result, they are forced to make friend. After that, they talk as well as understand deeply about each others. In addition, playing sports will teach them a practical lesion of winning or losing after the contest. When they win, they will be more confident to go ahead. However, as they are losers, they must stand up and try for the next one. It is very necessary for children to improve themselves by step. Overall, competition sometimes makes children feel stressful and tired; however, competitive sports are necessary for them to improve their abilities As a result, it is the vital key to go to the success in the future.
