Question: 1 / 445

What are some cellular benefits of cardiorespiratory conditioning?

Decrease in aerobic enzyme levels

Number and size of mitochondria decrease

Improved blood delivery and increase in capillary density

Some people may think that option A is correct because it talks about aerobic enzymes, which are important for energy production. However, cardiorespiratory conditioning actually increases aerobic enzyme levels, helping the body to produce energy more efficiently. Option B is incorrect because mitochondria are the "powerhouses" of cells and increasing their number and size is a desirable benefit of cardiorespiratory conditioning. Option D is incorrect because blood delivery is typically improved with cardiorespiratory conditioning, not decreased. Therefore, the correct answer is option C because it accurately describes one of the main benefits of cardiorespiratory conditioning - improved blood delivery and increase in capillary density.
