Vo2 max testing and training: What is it?

BY IN Exercise Institute News On September 9, 2015

Vo2 max testing measures the maximal amount of oxygen consumed by an individual when exercising. Exercising can be running, swimming, cycling, rowing and any other cardiovascular activity. Vo2 max testing aims to outline the maximum amount of metabolism achievable by a human, and even in animals.

Measuring Vo2 max involves analysis of the oxygen and carbon dioxide exchange across increasing levels of exercise until a platue in oxygen uptake occurs. The formula for this equation is known as the FICK equation which outlines the arterial oxygen content minus the venous oxygen content multiplied by cardiac output equals oxygen volume during exercise. Studies have found good positive correlation with the maximum amount of litres consumed of oxygen and athletic endurance performance.

The upper limits for human functioning can be as high as 98ml/kg/min in humans with certain breads of sled dogs as high as 240ml/kg/min. Research has even looked into measuring the Vo2 max of equestrian jockeys whilst simulating their gait cycle on a sprinting horse in an effort to quantify the demands of their event. This data can then be applied to training to ensure adequate adaptation ensues.

The testing for endurance athletes is even more specific as it hopes to outline critical speeds, pace and wattages that occur concurrently with different metabolic events along the way to Vo2 max. The importance here is when the individual is training, different intensities can be prescribed based on power, pace, speed etc that dictate optimal training intensity (that is neither too hard nor too light) which can induce the greatest adaptation in the shortest period of time.

The Vo2 max can occur prior to the end of the Vo2 test, meaning the actual intensity for Vo2 max can only be measured through gas exchange analysis

A good deal of research has looked into optimal training strategy for Vo2 max training and identified specific markers for tailoring training¬†intensity to best drive adaptation in the shortest period of training time. Importantly training intensity is then not tailored to how ‘hard’ one can go, but to the minimum output required to illicit Vo2 max. Something that can only be prescribed after a Vo2 test as this occurs prior to the Vo2 peak.

Once the test is completed an interpretation of the data via a report is offered with various markers of fitness offered. The test can be completed for runners, swimmers and cyclists at exercise institute, West Perth for as little as $200.
