Question

An endurance athlete exercising for more than 1 hour should consider replenishing fluids with an electrolyte drink. A popular serving size bottle of a drink such as Gatorade® has four 8-ounce (1-cup) servings per bottle. If there are 50 kcal per cup, how many kcal are in the whole bottle?

1) 200 kcal
2) 50 kcal
3) 400 kcal
4) 12.5 kcal

Answer 1

A bottle of a sports drink with four 8-ounce servings, each containing 50 kcal, results in a total of 200 kcal for the entire bottle. This replenishment, including necessary electrolytes, is important for endurance athletes engaging in extended exercise.

Step-by-step explanation:

Each 8-ounce (1-cup) serving of the sports drink contains 50 kcal. Since the bottle has four servings, to determine the total calories in the whole bottle, we need to multiply 50 kcal by the number of servings, which is 4. So, the calculation is 50 kcal/serving × 4 servings = 200 kcal for the entire bottle.

It is important for an endurance athlete to consider replenishing with a sports drink if exercising for more than one hour because it contains electrolytes such as sodium and potassium, which are crucial for rehydration and preventing fatigue during prolonged physical activities. These drinks are formulated to improve hydration and support athletic performance.
