Trich will not stop you from performing in sports in any way. The only issue is when you have a bald spot and getting in a pool or bouncing around will show people you don't want to know about it. So, people refrain from being active because they don't want their wig to come off or their hair to shift from covering their bald spot. Being physically healthy might improve the urges to pull or the duration of pulling time, or even increase time between pulling. But it might not. People pull when they are stressed but also when they are bored. It's not just one thing. Being as healthy as you can be will help you in more ways than just dealing with or helping to control pulling.
