bsolutely shouldn’t . There are some reasons. Firstly, when they are pushed hard they will be very stressful and it can easily cause these children to fail in their activities and this stress also can cause them to be weak physically. Secondly, they get easily bored to do the activities if they are pushed hard and because of this, they may not be active, enterprising, enthusiastic, bold and successful in their activities. Moreover, if they obey the decisions of their parents or coaches who push them hard, they can easily be submissive and may not take any decision on their own in the future. So, they may behave unsocially in their environment and this also can affect them to be unsocial in different areas. In the world there are many examples of this. Especially Chinese current government doesn't leave anything aside to apply on children athletes to make them successful(according to the things they said).Whatever we say somethings bad physical perspective, in some countries athletes are even not given any help , any financial assistance , for example Turkey, North Korea etc.Therefore , any child athlete is improved and made ready for olympiad or whatever. Pushing a child athlete hard in order to succeed makes him or her worse physically and mentally and inactive in too many areas they are in and they will be in. But it shouldn't forget that they need suppling, supporting ( morally , as required , not any more cruelly) .
