Describe the interrelationship between heart rate, oxygen uptake, and the expenditure of work, and explain why heart rate is useful for ergonomists in measuring metabolic processes

Mathai (2009) states the many physical and chemical processes which occur at the microscopic cellular level produce the cumulative effect of allowing the human body to perform activity and sustain life. When performing physical tasks the autonomic system reacts physiologically in order to support the activities being performed. There is however limits on the quantity and type of activity each individual can perform.
The primary indicators of health in a human are vital signs; blood pressure, body temperature, respiration and heart rates. ...
