Metabolic Testing

INSCYD is the most advanced tool to analyze endurance performance in athletes. INSCYD creates a full metabolic performance profile of an athlete. This includes: aerobic capacity, glycolytic capacity, anaerobic threshold, energy cost of locomotion, fuel contribution (Fat vs. Carbohydrate), lactate accumulation & recovery, aerobic vs. anaerobic energy contribution, and many more performance metrics.


A deeper dive

The performance you are looking for is composed of a variety of components and metrics. If you only focus on FTP, heart rate zones, or train only according to your Rate of Perceived Exertion, you’ll miss accuracy and efficiency. 

INSCYD takes into account and connects 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. Sports performance is predictable and can be broken down to these fundamental elements.

metabolic fingerprint

INSYCD measures a variety of metrics in order to establish the overall identity of an athlete. By creating a “metabolic fingerprint” athletes can better understand their strengths and weaknesses. This will allow them to construct more efficient training programs to help fine tune their training.


substrate utilization

One of the most interesting features of the INSCYD testing protocol is the substrate utilization graph. This allows an athlete to understand how many carbs they’re burning at a given intensity level allowing them to create a better fueling strategy.
