The study of cardiovascular fitness and health involves gaining insights into the physiology of the blood, heart, lungs, airways and vasculature. This advanced biology course is ideal for those wanting to understand cardiorespiratory fitness, sports performance and the appropriate exercises for maintaining health, including health professionals and sports coaches.
The Certificate of Human Biology – Cardiovascular Fitness and Health is an online professional development program that will give you insights into the vital processes that occur in healthy cardiovascular and respiratory systems, and the physiology, anatomy, biochemistry and basic physics that drive these processes.
In this human biology course, you will explore the science of blood and the factors that affect blood pressure, pulmonary ventilation, including the respiratory system, and how to measure lung capacity and function.
You will also learn about gas exchange and blood flow in the human body, cardiorespiratory control and the nervous system, and the various types of cardiorespiratory diseases.
On completion of this course, you will understand the impact of medical conditions and other factors on cardiorespiratory performance and how to regulate this vital multi-organ system.
