  16. What is your sweat rate? • Weigh yourself before and after a 1 hour workout • Get the difference of the two weights and multiply by 16 • Add the number of fluid ounces you drank during your workout

  17. What is your sweat rate cont. • For example: • Take a pre exercise weight of 200 lbs • After 1 hour of exercise they weigh 198 lbs • That’s a difference of 2 lbs • 2 X 16 = 32 fl. Oz. • Say they drank 16 oz of water during their workout • 32 + 16 = 48 fl. Oz. • In 1 hour this person lost 48 fl. Oz. through sweat

  18. What does your sweat rate mean? • Once you have calculated your sweat rate you will know how much fluid you need to: • Stay hydrated • Replenish fluids lost during exercise

  19. summary • Be aware of dangerous environmental conditions • Follow practice guidelines • They are there for your safety • Know the signs of heat illnesses • STAY HYDRATED
