Correlation is NOT Causation is a good thing to keep in mind in discussions of this sort. As is the Nature and Nurture argument.
For example: We see that that many endurance champions have a high maxVO2. The popular press and the uninitiated grab on to this correlation as proof of causation. We are incredibly complex organisms and singling out what traits make champions is not so easy. Scott S’s Derek Clayton example above is a great illustration.
In my own rather un-illustrious athletic career I was tested numerous times for maxVO2. My results placed me in the upper 1% of humans in terms of maximal aerobic power. True enough I did compete at an elite level but I was never among the top despite what should have been my genetic advantage. As a curious 20 year old this caused me to begin asking my first probing questions of the exercise scientists and started me down this path I am still on.
A few years ago I coached one Olympic XC skier who has one of the highest recored maxVO2 scores for any human, yet he is/was not competitive at the World Cup level. At the opposite end of the aerobic power spectrum I have also coached two other World Cup skiers with rather pedestrian aerobic power. One of them is a World Championship medal winner and the other a World Cup medal winner. Even in XC skiing which is considered to be the most demanding sport for aerobic power and makes he highest utilization of it, the correlation between maxVO2 and performance is poor.
I mention these examples as an illustration that endurance performance is the result of an incredibly complex interaction of many systems some that are genetic gifts and some that are the product of much hard work and many in between. While we can and do measure (in isolation) many things that we think relate to endurance performance; We really do not understand the full picture of endurance performance.
I suspect this test could very well tell you if you have certain genes that have some relation to certain physical traits. Measuring in isolation is something science is very good at. This might inform some training decisions or at least get you to try certain training interventions.
I’d save your money and get a Metabolic Efficiency test to determine you personal metabolic response to exercise intensity. Now, that is something you can do something with and that info will very powerfully inform you training training decisions.
I have a 4 part series of testing articles come to the website soon.
