Comprehensive Metabolic Profiling
Explore a comprehensive metabolic profile that uncovers your strengths and weaknesses. Our scientific metrics, such as aerobic capacity (VO2 Max), and anaerobic (VLa Max) capacity, offer unique physiological insights for each individual.
Obtain highly accurate training intensities to help you target specific intensities such as FatMax, and Maximum Lactate Steady State (MLSS), understand lactate accumulation and clearance levels, and optimize nutrition strategies, regardless of your event.
Athletes can conduct metabolic tests remotely with the Power Performance Decoder (PPD) using their GPS watch or power meter, or they can participate in lactate or VO2-based tests in the lab or out in the field. Learn More
We travel to various locations across the US (sometimes across the world) to provide service to our individual and group clients.

Knowing your Functional Threshold Power (FTP) derived from a 20-minute test may be a good way to contextualize your fitness level, but here's why many coaches and athletes might be overly reliant on FTP.
Beyond the Limitations of FTP
FTP is Not a Great Measure of Aerobic Capacity.
-
The FTP power is contributed by both the aerobic and anaerobic energy systems and two athletes could have the same FTP power but produced in very different physiological ways.
-
To track progress, you need to know how the body responds to training in more detail, by looking at changes in aerobic power (VO2max) and anaerobic power (VLamax).
FTP is Not the Same as Lactate / Ventilatory Threshold
-
Studies have highlighted significant differences between FTP and Lactate Threshold (LT2) as well as Ventilatory Threshold (VT2), and the difference varies based on the athlete's fitness.
Functional Threshold Power Is Not Equivalent to Lactate Parameters in Trained Cyclists (2021)
“We encourage athletes and coaches to use alternative field-based methods to predict cycling performance.”
"Power output and relative power output at the functional threshold power are higher than at the ventilatory threshold.”
FTP is Not Effective for Creating Training Zones.
-
Creating training zones based on percentages of FTP is not efficient and precise as two athletes could have the same FTP, but have completely different aerobic vs. anaerobic energy contributions, carbohydrate vs. fat usage, and lactate dynamics at the same percentage of their FTP.
Example of how the intensity at 120% FTP has a totally different impact on two cyclists.
THE SOLUTION:
360 Metabolic Testing by INSCYD
Similar to the FTP test, the INSCYD Power Performance Decoder only requires a power meter (cycling) or GPS watch (running), but provides a more comprehensive overview of your metabolic metrics, validated by research.
You can do the PPD test on Zwift, just like the Zwift Academy team does on the GCN YouTube channel.
"The INSCYD PPD test gives you a good insight on how you can manage your training."
--Matthew Van Der Poel
Cycling and Cyclocross World Champion
"With the help of the INSCYD software I have been able to cater my training to my own unique energy systems and tailor that plan to be efficient at the races and durations that I want to excel at."
--Lionel Sanders, Pro Triathlete
"INSCYD offers us the ability to create the most accurate measures of metabolic efficiency available today"
--Prof. Elliot Hawkes, Stanford University
Our Services
Lactate Testing
$249
In this 40-minute session, the athlete will complete four efforts of various intensities where blood lactate samples will be taken.
Unlike traditional step-tests that only estimate LT1 & 2, our lactate testing service creates a 360 metabolic profile by analyzing the test results using INSCYD analytic software.

Why should I consider metabolic testing?Each individual has their unique physiology, their own strengths and weaknesses, and therefore respond to training differently. Metabolic testing provides you data-driven insights of your physiology and allows you to reach your goals more efficiently by identifying your optimal training intensities, whether you're aiming to break personal records, compete at a higher level, or simply improve your overall fitness.
-
Do I need to be an elite athlete to benefit from metabolic testing?No, these tests are beneficial for athletes of all levels, from beginners to elite athletes. Understanding your physiological metrics can help you train smarter and achieve your personal goals, regardless of your experience level.
-
I already have a coach or follow a training plan. How are your services different?Our services complement your existing coaching or training plan by providing precise, individualized data that can enhance the effectiveness of your workouts. While your coach or plan offers structured guidance, our metabolic testing delivers insights into your unique physiological profile, such as your VO2 max and lactate threshold. This information allows you and your coach to refine your training zones, adjust intensities, and optimize your plan based on objective data rather than relying solely on general principles or subjective feedback. By integrating our testing with your current approach, you can achieve more targeted, efficient, and effective training, ultimately leading to better performance outcomes.
-
How often should I get testing done?The frequency of testing depends on your training goals and season. Typically, athletes benefit from testing every 3-4 months to monitor progress and adjust training plans. However, testing before starting a new training cycle or when making significant changes to your routine is also recommended.
