Question:
A young man is running his first marathon. Which of the following actions is taking place in his skeletal muscle when he runs, relative to when he is at rest?
Correct Answer: E. Increased lactate formation
Skeletal muscle circulation is controlled by local metabolic factors during exercise. The increased oxygen demand also results in increased CO2 production. This results in lactate formation (correct answer), which causes arterioles to dilate, resistance to drop, and metabolite concentration to increase.
