INSCYD provides us with a holistic and detailed insight into an athletes’ physiology. It explains how physiological metrics interact and compose an athletic performance.
INSCYD testing is for all athletes and all abilities.
INSCYD will benefit your training schedule and performance with both a scientific foundation and precise predictability.
INSCYD tracks every single metric and projects future performance outcomes.
With INSCYD you’ll get full picture of your physical capacities and also a prediction of your training and racing outcomes. 
The performance you are looking for is composed of a variety of components and metrics, but if you only focus on FTP/20min tests, heart rate zones, or keep training only according to your Rate of Perceived Exertion, you’ll miss accuracy and efficiency.
For example, with INSCYD you can finally understand the interactions between your aerobic system and your fuelling needs. Do you wonder, “How much should I consume per hour in order to maintain my performance?” With INSCYD, you'll know.
INSCYD takes into account, and connect to one another, the most important metrics for training purposes:
 
VO2max
Anaerobic threshold
Lactate accumulation and recovery
Fat and carbohydrates combustion
Recovery
VLamax (or glycolytic capacity) 
Each of the above metrics measured by INSCYD is critical to performance and remember, each sport performance is predictable and can be broken down to these fundamental elements. 
Take VLamax, for example. Although you might have never heard of it, VLamax. It is the single most important measurement to enhance your performance. VLamax is the maximum production of lactic acid in your blood and gives you a complete understanding of your anaerobic metabolism (which yes, is crucial in endurance events, too!). VO2max is aerobic, now we know the anaerobic piece, which turns out to be at least as important.
