Question 1:
Which macronutrient is the primary source of fuel during endurance exercise?
Explanation: The correct answer is A) Carbohydrates. During endurance exercise, the body primarily utilizes carbohydrates as the main source of fuel. Carbohydrates are efficiently converted into energy, providing readily available glucose for the muscles.
Question 2:
Which nutrient is essential for muscle repair and growth?
Explanation: The correct answer is B) Proteins. Proteins are essential for muscle repair and growth. They provide the building blocks (amino acids) necessary for the synthesis of new muscle tissue and aid in the recovery process after exercise.
Question 3:
Which nutrient is important for maintaining proper hydration during exercise?
Explanation: The correct answer is D) Electrolytes. Electrolytes, such as sodium, potassium, and magnesium, are important for maintaining proper hydration during exercise. They help regulate fluid balance and replace the electrolytes lost through sweat.
Question 4:
Which nutrient is the most concentrated source of energy?
Explanation: The correct answer is C) Fats. Fats are the most concentrated source of energy among the macronutrients. They provide more than twice the energy per gram compared to carbohydrates and proteins. Fats play a vital role in providing sustained energy during prolonged exercise.
Question 5:
Which nutrient is particularly important for bone health and preventing stress fractures in athletes?
Explanation: The correct answer is D) Calcium. Calcium is particularly important for bone health and preventing stress fractures in athletes. It contributes to the development and maintenance of strong bones and plays a crucial role in muscle contraction and nerve function as well.
