ConductMetabolism — Indirect calorimetry for exercise & metabolic phenotyping
ConductMetabolism is the measurement system and software that ships with the Rodent Metabolic Treadmill. Capture O₂, CO₂, RER/RQ, and energy expenditure — at rest or during graded exercise — with live monitoring and publication-ready export.
ConductMetabolism ships with the treadmill — it isn’t sold separately.

Parameters
Everything you need for a metabolic phenotype
Indirect-calorimetry parameters captured per second, derived live, and exported per animal. The core readouts link to full endpoint guides in the Science Library.
Oxygen consumption
Oxygen used per unit time — the primary index of aerobic metabolic rate.
View endpointCO₂ production
Carbon dioxide produced per unit time, paired with VO₂ for substrate use.
View endpointRespiratory exchange ratio
VCO₂ ÷ VO₂ — the fat-versus-carbohydrate fuel readout (≈0.70–1.00).
View endpointEnergy expenditure
Whole-animal energy use derived live from gas exchange, exported per animal.
View endpointGas flow & environment
Vin/Vout push or pull, plus temp ±0.1 ℃, humidity ±1 % RH, barometric pressure.
Per-animal statistics
Means ± SD computed per unit, ready to export to CSV.
One workflow
Configure, monitor, and analyze in one application
The same suite that powers ConductMaze — ConductMetabolism is a native module, not a separate tool. Set up the protocol, watch O₂/CO₂ live, then control the treadmill and export per-animal results.

Indirect calorimetry, explained
How VO₂, VCO₂, RER, and energy expenditure are derived from gas exchange — the method behind the measurement.
Exercise metabolism & VO₂max
Substrate use, endurance, and VO₂max under graded treadmill load, and how to design a graded-exercise test.
Treadmill exercise protocols
Ready-to-run rodent treadmill training and testing protocols, with a protocol-design tool.
Exercise metabolism
Built to run on the Metabolic Treadmill
The measurement system is fully integrated with the treadmill: program speed and acceleration steps, capture VO₂/VCO₂ while the animal runs, and correlate energy expenditure to workload — all on one timeline.
