Question

what is an adaptation of endurance exercise training? increased hr decrease in arterio - venous oxygen difference increase in capillarisation around skeletal muscles decrease in sv

Explanation:

Endurance - exercise training leads to physiological changes. One such change is an increase in capillarisation around skeletal muscles, which improves oxygen and nutrient delivery. An increased heart rate (HR) is not a long - term adaptation but a short - term response during exercise. A decrease in arteriovenous oxygen difference is incorrect as endurance training increases the ability to extract oxygen, increasing this difference. A decrease in stroke volume (SV) is also incorrect as endurance training typically increases SV.

Answer:

increase in capillarisation around skeletal muscles
