How to control my breathing

Question
We have just started our 3rd day of practice at middle school in the afternoon workouts for football. I am having trouble keepin my breath. I am just wondering if this is normal for a person my age adjusting to it or is it something else. I am 13 i weigh about 158 im 5'8 i can run a 40 in 555.

Answer
   Wyatt this is totally normal condition.  You are probable working harder than you have ever worked in your life.  As the season goes on and you get in better shape this will go away.  Also the summer heat adds to your breathing troubles.  Just be sure to drink plenty of water during and after practice.  GOOD LUCK COACH NOEL!
