What Is Cardiorespiratory Endurance?

Cardio-respiratory endurance indicates how your body responds during a long period of exercise. If you have high endurance, you can sustain high-intensity activities without getting tired.

One of the best ways to measure endurance is how well a person’s body takes in and utilizes oxygen. When you inhale, your lungs fill up with air, and oxygen passes into the bloodstream. This oxygen-rich blood reaches the heart and all organs that need it. During high-intensity and long-period exercises, muscles require an adequate supply of oxygen. If the muscles do not get enough nutrients, waste products begin to accumulate and cause fatigue.

Therefore, cardiorespiratory endurance directly affects your physical performance.

How to Measure Cardiovascular Endurance?


The simplest way of measuring endurance is how your heart and lungs deliver oxygen to your working muscles. But how do scientist measures cardio-respiratory endurance? Sometimes, they measure it through the air you breathe during vigorous activities.

Here are two tests that can measure endurance level:

  • Metabolic Equivalent
  • Maximum Oxygen Uptake

Let us discuss these methods in detail!

Metabolic Equivalent
MET – Metabolic Equivalents explain the energy difference during physical activity and rest periods. Finding a person’s METs refers to the oxygen amount inhale at rest.
Maximum Oxygen Uptake
The maximum oxygen uptake (VO2 max) test determines the maximum amount of oxygen the body is capable of using during high-intensity activities, such as sprinting or biking.
The VO2 max test typically involves running on a treadmill or pedaling on a stationary bike as fast as possible. During the test, the person wears a chest strap or other body attachment that records their heart rate and a face mask that measures oxygen consumption.

Additionally, you can measure cardiorespiratory endurance by using the below fitness methods:

  • The astrand treadmill test
  • 2.4 km run test
  • The multistage bleep test

Choose the cardiorespiratory test that suits your needs!

Why Is It Important?


As stated earlier that respiratory endurance indicates the level of your fitness. People who want to burn calories through high-intensity workouts should focus on cardio-respiratory endurance. Respiratory endurance enables a person to perform high-impact exercises for a long time.

Here are some science-backed benefits of having an improved cardio endurance:

  • A research study indicates that people with high cardio endurance are less likely to develop high blood pressure. While those with lower endurance are prone to blood pressure issues.
  • Another research study mentions the positive relation between cardiorespiratory endurance level and multitasking performance among adults.
  • Improved cardio-respiratory endurance may reduce the risk of coronary heart diseases and all causes of mortality.
