​There is a linear relationship between the heart rate and oxygen consumption

​There is a linear relationship between the heart rate and oxygen consumption (sub-maximal tests can be used to estimate a person’s aerobic capacity). Note about aerobic exercise, individuals diagnosed with coronary heart disease should participate in controlled aerobic workouts. And this brings about the need to understand congestive heart failure, which is caused by an enlargement of the heart in response to coronary artery disease (or chronic strain against the circulatory system that is used to create blood pressure – Peripheral Vascular Resistance).
