Question

why is it a good idea to wait at least an hour between eating and exercising?
a. exercising after eating will make you hungry again as soon as you finish working out
b. exercising after eating diverts the blood away from the heart
c. exercising after eating may cause dizziness and fatigue
d. exercising after eating can compromise oxygen and nutrient delivery to muscles.

Explanation:

After eating, blood is directed to the digestive system for digestion. When exercising immediately after eating, blood is diverted to the muscles. This can lead to insufficient oxygen and nutrient delivery to the muscles, as the body has to split its resources between digestion and exercise. Option A is incorrect as hunger after exercise is a normal metabolic response and not the main reason for waiting. Option B is wrong because blood is diverted to muscles and digestive system, not away from the heart. Option C is a possible symptom but not the root - cause explanation.

Answer:

D. Exercising after eating can compromise oxygen and nutrient delivery to muscles.
