Lactate Analysis - 60 Minutes
WHAT IS IT?
Lactate Analysis is an optional extra on top of VO₂ Max testing. Lactic acid is a by product of anaerobic metabolism, which is made up of 2 molecules: lactate and hydrogen ions. Hydrogen ions is what causes that burning, heavy and fatigued feeling during high intensity exercise. Hydrogen ions are impossible to test on the spot, but because there is a direct correlation between the concentration of lactate in the blood and hydrogen ions, we are able to determine the concentration of hydrogen ions using lactate analysis.
The lactate inflection point (LIP) is the point at which lactate production exactly meets lactate removal, and any further increase in intensity results in exponential production of lactate and hydrogen causing severe fatigue. Put simply, the lactate inflection point is your maximum threshold/Functional Threshold Power for aerobic exercise and is most useful for time trial events or events lasting under 1 hour.
DO I NEED IT?
Not necessarily, but lactate sampling will provide slightly more accurate training zones than VO₂ max testing alone. We generally recommend lactate analysis to individuals who:
- Are more interested in their training zones/functional threshold power than VO₂ max.
- Cycle with a power meter on their bike.
- Complete ultra distance events.
Our VO₂ testing unit measures your lactate inflection point based on ventilation and the point at which ventilation grows exponentially. This measurement is a very closely correlated with lactate and is generally very accurate. The $30 added cost is simply to cover the costs of the lactate strips, so we don't profit either way and it's totally up to you. You can always opt to have your lactate tested on the day if you are unsure or have any further questions.
The protocol is similar to the VO₂ max tests, however we will take a small droplet of blood before the commencement of the test, at every 3 minute interval during the test, and at the conclusion. In order to obtain a small blood sample we are required to 'prick' you with a small lancet needle in a finger or earlobe. This is virtually painless but is something to consider if you do not like needles.
WHAT DO YOU GET?
You will receive the same data as in the VO₂ max test, however you will also receive a graph showing your lactate results including your lactate inflection point and functional threshold based on lactate.
