Physiological Adaptations to Aerobic Exercise

The human body relies on a complex network of systems to maintain homeostasis, particularly during physical activity. When an individual engages in vigorous exercise, several physiological changes occur to meet the increased demand for energy and oxygen.

During exercise, there is an increase in heart rate, breathing rate, and vasodilation in the muscles being used. Hormonal responses, such as the release of adrenaline, also play a crucial role in preparing the body for increased physical stress. Understanding these processes is essential for recognizing how the body adapts to both acute and chronic exercise conditions.

Which of the following statements correctly describes a physiological adaptation that occurs in response to regular aerobic exercise?
