Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Most Cardiovascular Adaptations result in ____
A
Less oxygenated blood getting to the muscles
B
More oxygenated blood getting to the muscles
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Since the arteriovenous coronary oxygen difference shows little change, the increase in oxygen consumption of the heart muscle is primarily the result of an increased coronary blood flow. As the cardiac work rises more than the myocardial oxygen consumption, the left ventricular efficiency increases.

Detailed explanation-2: -After long term aerobic training, the body adapts to become more efficient at meeting the metabolic demands. The changes to the cardiovascular system include increased maximal cardiac output (Qmax), increased stroke volume (SV), and reduced heart rate (HR) at rest and during sub maximal exercise.
