Performance in endurance events is improved by a diet high in carbohydrates primarily because:
A)a high carbohydrate diet is required to maintain blood glucose levels.
B)a high carbohydrate diet maintains muscle glycogen levels.
C)a high carbohydrate diet stimulates muscle protein synthesis.
D)None of the above answers are correct

Question

Quizplus · Accepted Answer

Endurance events require prolonged physical activity and result in depletion of muscle glycogen stores. Consuming a high carbohydrate diet helps to maintain muscle glycogen levels, which in turn improves performance in endurance events. This is because muscle glycogen is the primary fuel source for prolonged exercise. Option A is incorrect because although blood glucose levels are important, they can be maintained within a normal range even with lower carbohydrate intake. Option C is also incorrect because a high carbohydrate diet does not necessarily stimulate muscle protein synthesis, which is more influenced by protein intake and exercise.
