ur child/children is/are super strong, it is not a great idea to let them to play the sports involved in too much body collision. You may want to use these sports to train them, but for some other people, those sports is their only hope to have a decent life. Look at the sports usally Chinese players can get to the top, those are the ones that we can be really good at. Boxing, hockey are not among them. Those players are the best among chinese, and have acquired very tough training.
just my two cents, especially to a parent from China.
