A)increased mitochondria volume in the muscle B)increased capillaries in the muscle C)increased hemoglobin in the blood D)increased muscle blood flow

Quizplus · Accepted Answer

While endurance exercise training can increase the amount of hemoglobin in the blood, this does not directly contribute to the increase in the maximal a-vO2 difference. The maximal a-vO2 difference is the difference in oxygen concentration between arterial blood and venous blood leaving the muscle, and is mainly influenced by factors such as increased mitochondrial volume, increased capillaries in the muscle, and increased muscle blood flow, which all improve the delivery and utilization of oxygen by the muscle.
