Communicating feelings, deep breathing and exercise are just three activities that help boost resilience in sports kids, says Dr. Randall Bell, a former youth sports coach and sports parent, a socio-economist and author of "Post-Traumatic Thriving: The Art, Science, & Stories of Resilience."

Coaches and parents can help kids bounce back after setbacks by encouraging them to talk about how they feel, helping them practice deep breathing and ensuring they get exercise. It's also important for coaches and parents to acknowledge kids' feelings and use positive language, he says.

Coaches naturally help accomplish these goals by providing an outlet for exercise, holding team meetings and being good listeners, he says.
