[Sports Activity After a Concussion Slows Recovery
Student athletes who return to sports quickly after a concussion appear to have a slower brain recovery than teens who stay off the field longer, a new study shows.

The report, from The Journal of Athletic Training, suggests that athletes who suffer from even mild concussions should slow down their return to the sports field. In fact, students with less severe injuries appeared to be those who return to sports the fastest. But resuming intense physical activity appeared to slow their recovery and even exacerbated their symptoms.

“By continuing with high levels of activity, they began to exhibit similar symptoms to those who initially experienced a more severe concussion,” said Jason P. Mihalik, an athletic trainer from the University of North Carolina and an author of the study. ]
