Abstract
This technical note describes methods to improve activity energy expenditure estimates using a multi-sensor board (MSB) by measuring slope. Ten adults walked over a 2.5-mile course wearing an MSB and mobile calorimeter. Energy expenditure was estimated using accelerometry alone (base) and four methods to measure slope. The barometer and GPS methods improved accuracy 11% from the base (

< 0.05) to 86% overall. Measuring slope using the MSB improves energy expenditure estimates during field-based activities.
