Cardiovascular System Responses to Exercise
This section examines how the heart, blood vessels, and blood adapt to the demands of physical activity, focusing on cardiac output and blood pressure regulation.
Cardiac Output and Stroke Volume
Cardiac output (Q), the volume of blood pumped by the heart per minute, is a crucial determinant of maximal exercise capacity. It’s calculated as heart rate (HR) multiplied by stroke volume (SV). Stroke volume, the amount of blood ejected with each heartbeat, increases during exercise due to enhanced venous return, increased contractility, and decreased afterload.
The textbook details how these factors interact to elevate Q, delivering more oxygen to working muscles. Understanding these physiological mechanisms is essential for optimizing athletic performance and assessing cardiovascular health. Adaptations to training significantly impact both SV and HR, ultimately improving Q and endurance capabilities.
Blood Pressure Regulation During Exercise
Blood pressure (BP) rises during exercise, but the regulation is complex. Systolic BP increases linearly with exercise intensity due to increased cardiac output, while diastolic BP remains relatively stable or shows a slight decrease. This is because vasodilation in working muscles reduces peripheral resistance.
The textbook explains how neural and hormonal mechanisms maintain BP homeostasis during dynamic activity. Factors like the baroreflex and sympathetic nervous system play vital roles. Understanding these regulatory processes is crucial for assessing cardiovascular risk and optimizing exercise prescriptions.
