In many cases, children reach adolescence with a sport under their belt. They started practicing it as children, in elementary school, and if it's a team sport, their commitment to competitions and their peers guarantee continuity during this period of change. But what about those who haven't played a team sport or regularly? If they haven't shown interest as children, it's hard for them to get hooked on a team sport at thirteen or fourteen. But this is neither impossible nor should it limit the highly recommended and necessary practice of sports. Miguel Ángel Méndez Pérez, a professor of health sciences at the UOC, is very clear about what families should keep in mind to achieve this goal.
