SweatStack Profiling

Unstructured athlete profiling for cyclists and runners.

Lab-grade results from the field.

The Problem

Lab testing is expensive, invasive and not scalable. Structured field testing is time-consuming and disrupts carefully periodized training plans. Most profiling solutions require inserting specific testing sessions, breaking up training flow and complicating AI-generated periodization.

The Solution

  • Input: Mean-max data from freeform training data.
  • Method: Automatically detects maximal efforts and estimates physiological metrics using metabolic modelling.
  • Output: VO2max, MLSS, FatMax, substrate utilization, training zones and more.
