Why is it Important to Stay Hydrated During Exercise?
Dehydration impairs your ability to perform athletically, and this impairment occurs when you lose as little as 2% of your body weight due to fluid loss. That equates to just 3 lbs (1.4 kg) for a 150-lb (68-kg) athlete. This degree of weight change due to fluid loss occurs commonly in many sports. To stay hydrated during exercise, it’s now highly recommended that you consume fluids at a rate that closely matches your sweat rate.
