Question

Maximal O2 uptake capacity of muscle - is there really a limit?

a) There is no limit to the O2 uptake capacity of muscle
b) The O2 uptake capacity of muscle is fixed and cannot be improved
c) The O2 uptake capacity of muscle can be improved with training
d) Age is the only factor that limits O2 uptake capacity.

Answer 1

The O2 uptake capacity of muscle can be improved with training.

Step-by-step explanation:

The correct answer is c) The O2 uptake capacity of muscle can be improved with training.

Endurance athletes can increase their O2 uptake capacity through training. This can be achieved by boosting the availability of oxygen to muscles by using substances such as erythropoietin (EPO) and human growth hormone (hGH). EPO triggers the production of red blood cells, which carry extra oxygen to muscles for aerobic respiration. hGH promotes the healing of muscle and other tissues after exercise, allowing for faster recovery and improved performance.
