The thirst mechanism is not precise in humans. An individual can lose fluids equaling up to 3% of their body weight before a person feels that they need to quench their thirst.
Strength and endurance are reduced by
Most people need more than eight glasses (8 ounces) of water per day. Water intake each day needs to be half your body weight in ounces. Do not drink more than 32 ounces at any one time. Water intake should be divided throughout the entire day.
If the exercise period is under 60 to 90 minutes, water intake is always appropriate. If the exercise period is more than 60 to 90 minutes, a sports drink offers an energy advantage that can enhance stamina and endurance.
Cardiac drift occurs because dehydration causes a drop in blood volume causing less blood to be pumped with each heartbeat. The heart rate increases 7 beats per minute for each 1% loss in body weight due to dehydration.
The keys to Proper Hydration:
Drink on schedule, rather than relying on thirst
Drink during training as well as competition
Drink cold water to increase gastric emptying
The American College of Sports Medicine on Exercise and Fluid Replacement (ACSM, 1996) states that adequate fluid replacement helps maintain hydration and, therefore promotes the health, safety, and optimal physical performance of individuals participating in regular physical activity.
