Question

Decides to test 4 different brands of sports drinks: Gatorade,

Vitamin Water, PowerAde, and Propel Water. He tests the
different sports drinks on the Varsity boys swim team at his
school. In his experimental group there are 5 different
17-year-old boys. Each boy tests each of the different
brands of sports drinks, and Carl measures their electrolyte
concentration in their blood.

Answer 1

The question focuses on the efficacy of sports drinks like Gatorade in replenishing electrolytes in athletes. Gatorade was formulated to enhance hydration, provide energy via carbohydrates, and prevent fatigue with electrolytes like sodium and potassium. Sports drinks vary in electrolyte concentration and are classified based on their content relative to the human body.

Step-by-step explanation:

The subject of the question pertains to the testing of sports drinks brands and their efficacy in replenishing electrolytes in athletes. Initially, Gatorade was formulated in 1965 to counteract the depletion of fluids and electrolytes in University of Florida football players. Not only did Gatorade provide rehydration, but it also contained carbohydrates for energy and was rich in electrolytes such as sodium and potassium to promote better fluid uptake and prevent fatigue during physical exertion.

All sports drinks are not created equal. They are classified into hypotonic, isotonic, and hypertonic, each differing in carbohydrate and electrolyte concentration. The American College of Sports Medicine suggests that sports drinks should contain at least 125 milligrams of sodium per 8 ounces to aid in adequate rehydration.
