Question
Here is the scenario: An athlete working out during the summer in the weight room weighs 175 lbs when he started working out. At the end of the workout he weighed 172 pounds. During the course of the workout which lasted 3 hours, the athlete drank 20 ounces of water. What is his sweat rate? Use the formula below to answer this question.
Calculate Your Sweat Rate What you will need: accurate scale and water bottle with ounce or milliliter (ml) markings.
1. Weigh yourself in minimal clothing before and after a practice that is at least 1 hour in length. Towel dry your body after practice before weighing yourself. Pre practice weight: _____________ kg Post practice weight: _____________ kg
*To convert pounds to kilograms, divide pounds by 2.2
2. Keep track of the amount of fluid you drink during practice. Fluids consumed: ____________ L *To convert ounces to liters (L), divide ounces by 34
3. Calculate change in body weight. Pre practice weight - post practice weight = ____________ kg
4. Add the amount of fluid consumed during practice to the change in body weight. Change in body weight (kg) + fluid consumed (L) = ____________
5. Divide above number by the length of practice (in hours) to get hourly sweat rate. Sweat rate = ___________ L/hr
Note: 2.2 pounds equals 1.0 kg and converts to a volume of 1.0 liter or 1,000 ml or 34 ounces of water. * This calculation will not be accurate if you used the bathroom during practice.
Explanation / Answer
1.ANS: 1 lb = 0.4535 kg or
To convert pounds to kilograms, divide pounds by 2.2
So
175/2.2= 79.54
172/2.2= 78.18
Pre practice weight: 79.54 kg kg
Post practice weight: 78.18 kg
2.ANS: 0.5882 Liter
To convert ounces to liters (L), divide ounces by 34
20/ 34 = 0.5882
1 Ounce [Fluid, US] = 0.0295735297 Liter
1 Ounce [Fluid, UK] = 0.0284130625 Liter
3.ANS: Pre practice weight - post practice weight = 1 kg
79.54 kg - 78.18kg = 1.36 kg
So the change in body weight is 1.36 kg
4.ANS: body weight (kg) + fluid consumed (L) =
1.36 kg + 0.5882 lit = 1.9482
