INSCYD test in cycling: Your metabolic fingerprint for training, pacing, and nutrition
Discover how your body uses energy with the INSCYD test. Optimize your training, pacing, and nutrition with your personal fingerprint.
Are you training hard but unsure whether you’re truly maximizing your potential?
Do you know your FTP or maybe even your VO₂max, but not how your body produces energy, burns fat and carbohydrates, or when it reaches its limits?
This is exactly where the INSCYD test comes in. It provides you with a complete metabolic fingerprint, showing you in black and white how your body works under stress, what your limiting factors are, and how you can perform at your best in training and competition.
What is the INSCYD test?
The INSCYD test is a modern form of performance diagnostics that was originally developed for professionals. Today, it is used by world-class teams, national teams, and an increasing number of ambitious amateur athletes.
The focus is on the Power Performance Decoder (PPD test). Unlike traditional lactate or spiroergometry tests, you can complete the PPD test entirely without a laboratory—either indoors on a smart trainer or outdoors with your power meter.
Based on your performance data, the INSCYD software creates a detailed profile of your energy metabolism – your own personal metabolic fingerprint.
What values are measured—and why are they so important?
VO₂max: Your engine size
Maximum oxygen uptake = the basis of your endurance performance.
VLamax: Your turbo
Indicates how much energy you can provide anaerobically. High = more sprint power, low = more efficiency.
FatMax & CarbMax: Fat and carbohydrate burning
Shows the intensity at which you burn the most fat or carbohydrates. This is crucial for your fueling strategy.
MLSS: Your metabolic threshold
The range in which you can maintain maximum performance without hyperacidity.
Lactate formation & breakdown
Reveals how quickly you recover and how to optimally control your intervals.
Substrate utilization
Shows exactly how much fat and carbohydrates you consume at different wattages.
