A non-athletic student from the physiology lab was inspired by the VO2-max test and decided to go train for a bike race. Over time, she increased the mitochondrial density in her leg muscles by 10%. If she comes back to do the VO2-max test again, what will be the most likely effect of training on a-v O2-difference?

there will be increase in VO2 max after the training

Explanation:

After the training, there will be increase in VO2 max test result which is the measure of maximal rate of oxygen utilization during exercise. This occurs because there is increase in mitochondrial density which increases the available ATP ultimately resulting in high consumption of oxygen during exercise or training
