Remote Lab-Level Testing for Your Athletes – Using Just a Power Meter or GPS Watch
Remote Lab-Level Testing for Your Athletes – Using Just a Power Meter or GPS Watch
The Power Performance Decoder (PPD) is a remote performance test. It provides the same lab-accurate metabolic profile you’d get from a professional performance lab – VO₂max, VLamax, thresholds, FatMax & more – using only a power meter (for cycling) or a GPS watch (for running).
- Lab-level insights anywhere
- Scalable for coaches & labs
- Remote & easy

Old Way
Why Conventional FTP & Power Testing Falls Short
Conventional field tests and FTP-based models only show how much power an athlete produces — not what limits their performance or how to improve it. Lab tests provide accuracy, but they require time, money, and access that many athletes don’t have.
FTP & Power Curves Are Limited
They show output, but not the physiological systems behind it.
Labs Aren’t Always Accessible
Expensive equipment, limited availability, and travel make it hard to test consistently.
Not Scalable Across Athletes
Lab-based testing makes it hard to regularly assess multiple or remote athletes, limiting ongoing progress tracking.
That’s why we created the Power Performance Decoder (PPD) — to give coaches and labs the same accuracy as a full performance lab, with the simplicity of a remote test.

The human performance lab you always wanted
Without visiting a lab, you can obtain a full performance profile of your athlete – and obtain the same result you could only get in the best equipped labs.
More specifically, with the INSCYD power performance decoder test you now can:
- Obtain data on the road, on the bike, on a track.
- Ensure lab test accuracy.
- All you need is power meters (power) or GPS watches (speed)
- Increase revenue by offering remote lab-level testing
How the Power Performance Decoder works
- Instruct your athlete to carry out four specific maximum efforts of a duration of 20 seconds, 3 minutes, 6 minutes and 20 minutes.
- Use additional power data from non test-specific data if desired (not necessary).
- Receive the data from the athlete via a training platform (TrainingPeaks or similar) or via email.
- Enter the specific power values of the maximum tests into INSCYD.
- Receive a full physiological performance profile of ALL the metrics that are available in INSCYD (VO2max, VLamax, FatMax, anaerobic threshold, carbohydrate combustion, aerobic and anaerobic energy contribution, and more).
