Brief Summary
The aim of this study was to find functions for estimating energy expenditure in free-living conditions. This method was based on accelerometry data acquired from a smartphone worn in a trouser pocket. The developed functions have been compared to the estimations provided by two research devices named Armband and Actiheart.

Outcome Measures
Primary Outcomes (1)
Accelerometry
Measures acquired by a smartphone (it contains several sensors, including a tri-axial accelerometer)
about 17Hz (duration: 3h30 in controlled conditions; 12 hours in free-living conditions)
Secondary Outcomes (2)
Energy expenditure
one point recorded each minute for 3h30 in controlled conditions or 12 hours in free-living conditions

EXPERIMENTALInterventions
Volunteers were asked to perform several activities such as walking at different paces, running, sitting, standing still or taking public transportation for about 3h30 They wore 2 research sensors that estimate energy expenditure: Armband and Actiheart. They also wore a smartphone (in a front pant pocket) that collected accelerometry data.
Volunteers were asked to wear sensors during about 12 hours, one day. They wore 2 research sensors that estimate energy expenditure: Armband and Actiheart. They also wore a smartphone (in a front pant pocket) that collected accelerometry data.
