How would you convince a football coach that a sports drink would be better than water for his high school athletes during two-a-day practices?
What will be an ideal response?
When exercise extends beyond 1 hour, sports drinks can offer several advantages over water alone-even more so in hot weather (Fig. 11-14):
Carbohydrates in sports drinks supply glucose to muscles as they become depleted of glycogen, thus enhancing performance.
Electrolytes in sports drinks help maintain blood volume, enhance the absorption of water and carbohydrates from the intestines, and stimulate thirst.
