Go the distance Water is the most abundant substance in the human body and is essential for normal physiological function. Water loss due to sweating during exercise can result in decreased performance and other problems. Staying hydrated is imperative for athletic performance on every level. Fluids should be consumed prior to, during, and after exercise, especially when extreme conditions of climate, exercise intensity, and exercise duration exist. Approximately two glasses of fluid should be consumed two hours before exercise and at regular intervals during exercise; fluid should be cool, not cold (59 to 72° F, 15 to 22.2° C). Flavored sports drinks containing electrolytes are not necessary for fluid replacement during brief periods of exercise, but they may be more effective in encouraging the athlete to drink frequently and in larger amounts. Sports drinks are designed to replenish what is lost during activity. Sweating is what the body does to maintain its core temperature, resulting in the loss of water and electrolytes. Electrolytes are essential minerals including calcium, chloride, magnesium, potassium and sodium. Electrolytes carry energy through the body, hence the name, "electro." Studies have shown that even a 2% loss in body weight can lead to impaired performance and a 5% loss in body weight can lead to heat exhaustion. Endurance and Replenshiment products at Henry's |
