ok so i'm going to be a freshman this september & i joined tennis with all my friends. so today was our first tennis practice, and we went on the track to run (the track is huge, btw) and we had to do 3 laps. it was a specific kind of running where we had to bring our knees up to our chest. but anyway after all the laps i wasn't feeling well and i threw up (it was only alittle bit, and nobody saw) and i'm worried that it might happen again tomorrow. do you think it will? and what are ways of preventing that kinda thing? give as much advice as you can!
