CPET interpretation software

your CPET data contains more than your report shows.

Aevox surfaces thresholds, substrate curves, and fueling targets that standard reports discard — built on exercise physiology, not just software.

Currently in pilot with clinical performance partners.

Aevox

the interpretation gap

01

A maximal test produces thousands of data points. Most reports give you one number.

02

Threshold detection varies by lab, by technician, by software. The physiology doesn't change. The interpretation does.

03

The substrate curve — your fueling prescription — is sitting in your raw data. Most reports never show it.

Aevox

what Aevox does

Four interpretation layers on top of standard metabolic-cart output — the analyses your physiology textbook describes, applied automatically to every test.
