Performed on your bike, with my power meter. You pay $8 per strip with your Client Discount or $10 per strip for a single session test.
While cycling at specified zones, I draw a small drop of blood from the ear and apply the strip to it. I then put the strip into my Lactic Analyzer and it reports a number. Then, we increase wattage until Lactic Threshold data is collected. Typically, this requires 5-6 strips and is a 1 hour test including warm up and cool down.
