Dr. Una May:

I want to add to that. Our research has found that children who are involved in more activities will prolong their involvement in sport because where one sport might disappoint them, because they do not make the team, they will have something else in their lives as opposed to the one sport being their only focus in life and they will not drop out completely. The research shows that if they get involved in different kinds of activities, the chances are that they will stick with at least one or two of them as they go forward.
