The energy behind every power number.
Aerobic & anaerobic energy contribution is the share of aerobic and anaerobic metabolism in your total power output or speed: the percentage of energy from each system, at any speed or power.
INSCYD computes it from tests you already run: a field lactate test, a lab test, or a ride or run recorded with a power meter or GPS watch.

Where the energy comes from.
Every power output or speed creates a metabolic demand, and your body covers it from two sides. Oxygen uptake covers the aerobic share: the steady, sustainable source using fat and carbohydrates as a fuel for the metabolism in mitochondria. And then there is a share of energy that is not covered aerobically but anaerobically. Under steady-state conditions that share comes from glycolysis.
Metabolic demand & VO₂
Athlete phenotype and training status.
The aerobic vs glycolytic energy share is ruled by the maximum capacities of both aerobic and glycolytic metabolism.
Simplified speaking think about it this way. The power output or speed, so basically the load, creates a specific energy demand. This demand has to be covered. The stronger one system is, aerobic or glycolytic, relative to the other one decides the energy share. This means: in athletes with a relatively good developed VO₂max but a relatively low VLamax, the energy demand will be primarily met by the aerobic system. In contrast: an athlete with a relatively high VLamax but relatively low VO₂max the glycolytic system will provide a bigger energy share.
From the tests you already run.
INSCYD computes the aerobic and anaerobic contribution as part of the full metabolic profile, from whichever data you can collect.
Lab-grade accuracy and quantity of data, in real world conditions. Any protocol, any sport: on the road, on the track, on the pitch, in the pool.
