Performance Assessment: Advanced Metabolic Testing
Get powerful, actionable data and recommendations.
Why does it work?
The result is a full metabolic profile - measuring VO₂max, VLamax, FATmax, and Anaerobic Threshold to provide athletes with customized, actionable recommendations and training zones based on physiological conditions instead of estimates.
“The testing process was straightforward, easy to execute and easy to understand. I left with relevant numbers, and specific, actionable training recommendations based on my test results. Leaving with specific training recommendations was a huge plus, many testing protocols simply spit out physiologic data.” - Sam Bassetti, Professional Road Cyclist - Voler Apparel Factory Racing
What is a Performance Assessment?
Our Performance Assessment uses the advanced INSCYD analysis platform to deliver deep physiological insights - including your VO₂max, VLamax (lactate production rate), anaerobic threshold (MLSS/AT), FATmax, and custom training zones—all without the need for headgear or face masks. It’s perfect for field testing across running, cycling, swimming, and rowing.

“I’m training for a 100-mile trail race and was looking for some expert help with training and nutrition. The session was super thorough, and the results were broken down in a really clear, practical way. Tim & Caroline took the time to answer all my questions. I left feeling way more informed and confident about what’s ahead. Highly recommend!” -EK
