Metabolic Cart Testing: VO2Max, Oxygen Uptake, & Lactate

Fast Talk Laboratories is pleased to offer lab-grade metabolic testing on our own, in-office Parvo Medics TrueOne® 2400 metabolic cart and Wahoo KICKR Core smart trainer. Lactate testing is available during this test for an additional fee. This testing is available to nonmembers and to members at a discounted rate.

After scheduling your Metabolic Cart test, you will come to our Boulder, Colorado office for your test administered by our Head Coach Ryan Kohler. Depending on the goals of your test, your test may include a step/ramp or VO2max protocol. Expect your test to last 30-45 minutes.

Coach Ryan will analyze and interpret your test results to offer your:

  • Ventilatory thresholds that identify key metabolic changes
  • Heart rate-based training zones
  • Power and heart rate-based training zones
  • Fat and carbohydrate oxidation for nutrition planning and for tracking progress
  • VO2 max, or VO2 peak, depending on protocol type

Lactate Testing

Fast Talk Laboratories is pleased to offer lab-grade lactate testing to nonmembers and to members at a discounted rate.

After scheduling your Lactate Test, you will come to our Boulder, Colorado office for your test administered by our Head Coach and exercise physiologist, Ryan Kohler.

The testing protocol is similar to the Metabolic Cart Testing but measures lactate parameters and does not include ventilatory parameters.

After your test, Coach Ryan will analyze and interpret your test results to offer your:

  • Lactate thresholds (LT1 and LT2) indicating key metabolic changes throughout the test
  • Heart rate-based training zones based on lactate response
  • Power-based training zones based on lactate response
  • Peak lactate and lactate recovery (depending on the testing protocol)

If you like, you can opt to get a resting metabolic rate measurement. This requires a four-hour fast before your test and adds about 30 minutes to the total testing time.
