Step-by-step explanation:
The word that would be used to describe football players drinking sports drinks after running drills all day is rehydrating. This process includes the replenishment of fluids, carbohydrates, and electrolytes lost during vigorous activities such as football drills. Gatorade, a drink formulated at the University of Florida specifically for their football players, was designed to aid in this rehydration by providing a balance of water, electrolytes, and carbohydrates that could help prevent heat-related illnesses and improve athletic performance. Sports drinks are generally classified as hypotonic, isotonic, or hypertonic, depending on their particular concentrations of salts, sugars, and carbohydrates relative to human body fluids, and they function to ensure hydration and energy for athletes.
