Description

This article compares four methods, three of which were previously published. The newly developed model is a modification of the Hildebrand et al. (2014) model and predicts oxygen consumption (VO₂) using Euclidean Norm Minus One (ENMO) from an ActiGraph worn on the right wrist. Mean absolute percent error was 24.59 (overall), 23.39 (sedentary), 19.34 (light), 50.91 (moderate), and 3.45% (vigorous). Percent accuracy was 54.0% and sensitivity and specificity ranged from 37 to 98% and 60 to 99%, respectively.

Development/Validation

Sample: 51 (29 males) healthy adults, 18-40 years of age

Setting: Laboratory

Activities: Cycling, sports, stairs, stationary, treadmill walking and running

Criterion: Oxycon Mobile (VO₂), activity type

Accelerometer(s): ActiGraph GT3X+ on right wrist

Validation approach: Comparison to criterion

Phase Designation

(What's this?)

This model is in Phase 1.
