Answer 1

Regular exercise training leads to an increase in maximum oxygen consumption, indicating improved cardiovascular fitness.

Step-by-step explanation:

The correct answer is option b. An increase in maximum oxygen consumption. When the body engages in regular exercise training, the heart and lungs become more efficient in delivering oxygen to the muscles. This results in an increase in the maximum amount of oxygen that can be consumed by the body, known as maximum oxygen consumption or VO2 max. A higher VO2 max indicates improved cardiovascular fitness.
