Description

Single and 2-regression models for predicting activity energy expenditure in children and adults wearing an Actical accelerometer on the right hip or non-dominant ankle or wrist were developed. Twelve total models are presented- with all combinations of model type (single or 2-regression), sample (children or adults), and monitor wear location (wrist, ankle, hip). For children, overall mean differences compared to the criterion ranged from 1.3 (hip 2-regression) to 12.0 (ankle 2-regression) kcal/kg/min. For adults, differences were 7.1 (hip 2-regression) to 27.4 (ankle 2-regression) kcal/kg/min.

Development/Validation

Sample: 48 (26 males) healthy children (8-17 years of age) and adults (men: 34±8 years, women: 39±10 years)

Setting: Laboratory

Activities: Activities of daily living, overground/self-paced walking, stationary, treadmill walking and running

Criterion: VmaxST portable metabolic system (VO₂)

Accelerometer(s): Actical on non-dominant ankle and wrist, right hip

Validation approach: Comparison to criterion

Phase Designation

(What's this?)

This model is in Phase 1.

Instructions

Actical counts/min are used as the input in to either single or 2-regression models to predict activity energy expenditure (kcal/kg/min). Separate models are available for children and adults and for each monitor wear location (ankle, hip, wrist).
