Current TrailGenic Usage

An exploratory field estimate associated with aerobic performance, distinct from directly measured oxygen uptake.

Retain the calculation, input sources, protocol, units, and model version wherever an estimate is displayed. Hiking heart rate, pace, gain, and duration can describe field performance; their combination requires validation before being treated as measured VO₂max. Altitude, terrain, weather, and device uncertainty affect comparison.

How to Use the Term

Keep context, behavior, recorded response, follow-up, and interpretation distinguishable. Ella examines longitudinal patterns and alternatives; a decision rule remains dated and revisable.
