Cardiovascular endurance, is also known as aerobic fitness stamina. Basically it’s the ability to exercise non-stop for very long periods without tiring. In fact it is a vital component of many sporting activities.
A person’s aerobic fitness level is based on the amount of oxygen which can be delivered by the body to the working muscles, and with how much efficiency the muscles can use that oxygen.
In order to gauge aerobic fitness of a person the standard test which is followed is the maximal oxygen uptake (VO2max) test. However, this test is expensive and consumes lot of time, that’s why some simpler tests have been designed to estimate a VO2 max score.
These varied kinds of tests for aerobic fitness are split into two broad categories, such as maximal or submaximal tests. In maximal tests the body is put to stress by exercising it to exhaustion, so they are not suitable for older, obese, young or the unfit. The submaximal tests are less demanding and are appropriate for these individuals, however, they are not very accurate.
Let’s check out what a standard aerobic endurance test will test:
Endurance of Cardiovascular Activity
Lower levels of cardiovascular endurance are usually connected to potential health problems such as heart disease, so it is vital that you take part in the test as well as set benchmarks to improve on your fitness test results.
The aerobic endurance test will gauge your capacity to sustain high levels of activity that use many muscles at a time plus this test will also gauge your recovery rate which is a vital component in measuring your overall cardiovascular health.
Your endurance level depends on how much oxygen your muscles get to absorb – the more oxygen is taken up, the higher endurance you will have. It’s vital to test this to correctly assess your overall health. Oxygen allows the blood to flow non-stop throughout the body and makes sure that your muscles achieve maximum results when training.
There are two crucial factors that are taken into consideration. The amount of blood that is actually reaching the muscle and with how much efficiency your muscles are absorbing the oxygen from the blood. It’s a fact that an average healthy person’s working muscles take up three times more oxygen than resting ones.
Laboratory tests are a little more expensive than predictive tests of aerobic activity however they yield specific results. In a laboratory test you are put to work on a treadmill, and your muscles work load is increased until there are clear indications that you have increased your heart rate and exerting each muscle. This yields most complete results regarding your oxygen uptake however it is a very long process hence is a lot more costly.
Predictive results are the fitness testing method of choice where your heart rate is measured over a period of high impact exercise, and a final calculation is made to predict your oxygen uptake. Although these tests are not 100% accurate but are regarded as very close and are low cost.
