Description

Combination of 7 accelerometers (15 total axes) is used to predict energy expenditure using a simple calculation converting acceleration into velocity and then, work. The sample involves three adults performing walking and running activities. Correlations between the criterion and prediction for specific individuals were 0.9571, 0.9818, and 0.9019.

Development/Validation

Sample: 3 male adults in their 20s

Setting: Laboratory

Activities: Treadmill walking and running

Criterion: Cosmed K4b2 (VO₂)

Accelerometer(s): Analog Devices ADXL210E on both arms, thighs, ankles and IDEEA on chest

Validation approach: Comparison to criterion

Phase Designation

(What's this?)

This model is in Phase 0.

Instructions

Acceleration is filtered using a low and high pass filter (more details not provided) and integrated to calculate velocity which is used to calculate kinetic energy and then total work (energy expenditure).
