Cardiorespiratory endurance is an indication of overall physical health. Tests to measure this monitor how well the heart, lungs, and muscles perform during moderate to high intensity exercise.
Increasing cardiorespiratory endurance improves oxygen uptake in the lungs and heart and can help a person sustain physical activity for longer.
Other names for cardiorespiratory endurance include cardiovascular fitness, cardiovascular endurance, and cardiorespiratory fitness.
In this article, we discuss what cardiorespiratory endurance is, how a person can measure it, and why it is important. We also look at how to improve cardiorespiratory endurance, including some examples of exercises.
What is it?
Cardiorespiratory endurance measures how well the body performs during long periods of exercise. A person with high cardiorespiratory endurance can sustain high-intensity activities over an extended period without getting tired.
Measuring a person’s cardiorespiratory endurance involves examining how well their body takes in and utilizes oxygen.
When a person inhales, their lungs fill up with air and some of the oxygen it contains passes into the bloodstream. This oxygen-rich blood then travels to the heart, which circulates it around the body to the tissues and organs that need it.
The muscles require an adequate supply of oxygen and other nutrients to work properly during high-intensity or extended periods of exercise. If the muscles do not get enough nutrients, waste products begin to accumulate and cause fatigue.
