What is INSCYD?
INSCYD is a powerful training tool that helps athletes and coaches improve performance with detailed physiological insights.

Metabolic Fingerprint
The metabolic fingerprint is a unique profile of an athlete’s energy systems, showing how their body produces and uses energy during exercise. It includes key metrics like VO2max, lactate dynamics, fat and carbohydrate usage, and anaerobic power. This data helps optimize training, pacing, and nutrition for peak performance and efficiency.


Performance Markers
Performance markers are key physiological metrics that define an athlete’s capabilities and guide training decisions. They include:
-
VO2max – Maximum oxygen uptake, indicating endurance potential.
-
Lactate Threshold – The point where fatigue increases, crucial for pacing.
-
VLaMax – Anaerobic power, affecting sprint ability and endurance.
Performance Development
The Performance Development analysis tracks an athlete’s progress over time by measuring key performance markers like VO2max, lactate threshold, VLaMax, and energy utilization. It helps identify trends, assess training effectiveness, and fine-tune strategies for continuous improvement and peak performance.
How the Pros Use INSCYD
"INSCYD helps me the most before the major training periods because we want to make sure that we make the best possible training program."
- Mathieu Heijboer,
Head Coach Team JUMBO-VISMA
"The Power-Performance Decoder is like a remote controller, and nowadays crucial to give us coaches an insight in the riders their actual level."
- Kristof de Kegel,
Coach of Mathieu van de Poel
and Team Alpecin FENIX
"INSCYD offers us the ability to create the most accurate measures of metabolic efficiency available today."
