Step 1
How are the demands of the athlete’s body at rest met with the reduced resting heart rate?
Answer
With a reduced resting heart rate, the athlete's body efficiently meets its demands through an increased stroke volume. Stroke volume refers to the amount of blood pumped by the heart with each beat. As the body becomes more conditioned through aerobic training, the heart becomes stronger and can pump more blood per contraction. This adaptation means that even with fewer beats per minute, the heart can maintain adequate circulation to meet the body's oxygen and nutrient needs during rest. Therefore, option (C) is the correct answer.
