Do you feel a lactate profile test isn't providing the complete picture of an athletes performance?

The Issues

  • Lactate profile curves depend heavily on the protocol used—making results from different tests difficult to compare.
  • Conventional lactate tests don’t provide VO₂max, even though it’s a critical marker for endurance and health.
  • VLamax, the key metric for anaerobic capacity, isn’t captured in traditional lactate tests and requires extra, non-validated sprint tests.
  • Conventional lactate tests don’t provide fat and carbohydrate combustion analysis, leaving you blind to critical fueling and FatMax data.
  • A simple right or left shift of the lactate profile curve doesn’t  provide insights into the training adaptation causing that shift.

INSCYD’s Solution

  • With INSCYD, you can follow any testing protocol you want—your results will be comparable across all tests.
  • INSCYD provides VO₂max directly from your lactate test—scientifically validated matching the accuracy of the best metabolic carts.
  • INSCYD makes VLamax available directly from your conventional lactate test—no additional tests needed.
  • INSCYD provides FatMax, fat- and carb combustion rates for every intensity—perfect for fueling and nutrition strategies.
  • INSCYD’s complete metabolic profile tracks aerobic and anaerobic separately—giving you a clear, detailed picture of what’s really improving.

One Test = A Complete
Performance Picture

Get everything in one test — revealing the full physiological breakdown that truly drives endurance success.

  • VO2max & VLamax – Aerobic capacity vs. glycolytic power.
  • Carbohydrate & Fat Combustion – Fueling insights for precise race nutrition.
  • Lactate Recovery & Accumulation – Understand fatigue and endurance potential.
  • Aerobic & Anaerobic Contribution – Pinpoint energy system demands at every intensity.
  • LT1, MLSS, Glycogen & more – Optimize pacing, intervals and long-term endurance strategies.

What coaches and labs say about INSCYD

"After starting with INSCYD, it was like a snowball effect. We went from having 20 runners in the program winning about 30 medals last year. This year our athletes won 160 medals with 23 champions, 29 Runners-Up (2nd) and 22 third place finishes."
