This is the warm up...

What is it?
The wVO2max Test is a semi-stressful, semi-endurance based test that is carried out for a period of six minutes. It includes a ten kilometre warm up and ten minute cool down.

More Information
To better understand the physiological issues this test addresses please read our VO2max Factsheet.

Why do I need it?
This test is used to determine an athlete's minimal wattage at which maximal aerobic capacity is attained. It tells you their sustained wattage output at their maximum oxygen consumption, which is indicated by the term, wVO2max.

Basically, it's the start of the Red Zone which, when racing, should be crossed only when absolutely necessary.

It further reveals an athletes aerobic capability and efficiency during endurance activity. It is one of the most powerful predictors of an athlete's endurance performance.

Without a clear wVO2max index, improving it can be a hit and miss affair. If you want to improve your cycling this is the test for you.

How to Prepare
This is a semi-strenuous test that takes you to the edge of your physiological aerobic capabilities and places a significant strain on your body. It is very important to make sure you:

are fully rested
are fully hydrated
have had no hard rides for at least two days previous
have not eaten for at least two hours previous
have been of good health for at least four weeks
have good motivation and morale
are mentally prepared for the sustained effort required

vo2max resultsThe Test
A wVO2max test is not a pleasant experience.

However, the result it provides give an excellent indicator to the endurance capacity and race winning potential of an athlete.

After a thorough warm up, stop, compose yourself, take a drink and let your heart rate "settle".

Ease in to the start of the test, taking a full minute to build up to the pace to where you think you need to be, to enable yourself to get to the end.

From the one minute build up, to the drop off point, start the test!  Take thirty seconds to ramp up to your hoped for, steady-state, speed or power. DON'T use or rely on heart rate.

Hold it at your limit for as long as you can and just concentrate on getting to the end. Do not sprint at the end or go in to ramp up mode. You'll only skew your lactate reading and might make 2 watts difference to your overall average. Ragged edge, steady state is the key.

Maintaining constant effort, and concentrating on form and technique in the test are critical to the accuracy and repeatability of the results.

The Result
The results of a wVO2max test provides crucial information in the preparation of a personalised athlete performance programme.

The information gleaned will allow the development of a training plan to improve wVO2max, lactate threshold, efficiency at VO2max pace, strength and power all in one six week training period!

Apart from the physiological rewards, the confidence and psychological edge to be gained from this test, and subsequent programme, make it an extremely efficient and effective use of your training time.

But the ultimate success of a test and programme, is measured by results gained on the road...
