It is defined as a measurement of the body’s ability to supply oxygen and other fuel to the muscles during long periods of activity. Experts measure how well your heart and lungs deliver oxygen to the working muscles so that they can work hard during exercise.
Practically, it is the ability of your body to keep exercising for a long time without stopping. It is also called aerobic capacity, cardiovascular fitness, and aerobic fitness.
Scientists test the air that you breathe out during vigorous exercise. By analyzing your exhaled air, they can estimate how efficiently your muscles are using oxygen. It is called as VO2 max test and it requires that you work at an extremely vigorous intensity. This test is performed in the laboratory as it is not safe for everyone.
In gyms, submaximal cardiorespiratory tests are more common as they are safe for exercisers who are out of shape or who might have heart problems. These test might include:
- Treadmill tests
- Bike tests
- Outdoor fitness walking test
- Step test
Cardiorespiratory endurance test helps the trainer to know how well you can perform cardiovascular exercise for a period of time. Exercisers with lower CRF will begin with shorter, less intense workout sessions and one with higher CRF start with intense workouts.
If your cardiorespiratory endurance is good, that means you are healthy enough to participate in the activities that will help you lose weight.
How to Improve Cardiorespiratory Endurance?
You can improve your cardiovascular endurance by practicing harder level of aerobic activity. Perform cardio type training 4-6 times per week. Training less frequently will benefit you in terms of fat burning, cardiovascular efficiency, and muscle endurance. Here are some exercises which promote cardiorespiratory endurance:
