Summary

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

Conditions

Interventions

BEHAVIORAL

Controlled conditions

The 13 volunteers in controlled conditions performed each of the nine activities several times according to the activity scenario: sitting, slow, normal and brisk walking, climbing and descending stairs (eight floors), standing, slow running and taking public transportation (tramway). The duration of each activity varied from 2 to 20 minutes.

BEHAVIORAL

Free-living conditions

The spontaneous activities of 30 volunteers were recorded in the free-living conditions for a full day selected either during the week or the weekend.
