Summary

In this study, the investigators propose to assess the validity in measuring physical activity (PA) of a new PA monitor system the MOTIONPODTM, that coupled a hip-worn multi-sensor device (associating a tri-axial accelerometer, a magnetometer and a gyroscope) with an automatic activity/posture recognition algorithm and an activity-specific multilinear prediction model. The MOTIONPODTM performances in predicting mean daily PA energy expenditure (PAEE) will be calculated against the reference PAEE gold standard measure, using the doubly labeled water method (DLW). The MOTIONPODTM performances in predicting PAEE and PA patterns will be compared to those of two existing activity or movement monitors: the triaxial accelerometer ActigraphGT3X+TM and a device combining cardiofrequencemetry with accelerometry, the ActiheartTM. This latter has demonstrated fair performances but at the cost of a calibration of the heart-rate/EE relationship that limits its use in large population samples. Briefly, this open study will include 120 subjects, aged 18 to 75 years of both gender and with broad range of body mass index and physical activity level. The subjects will carry a MOTIONPODTM, an ActigraphGT3X+TM, an ActiheartTM and a GPS for a total of 14 days in everyday life conditions and complete a physical activity diary. In half of the subjects, PA will be evaluated on a period of 14 days, with standard PAEE measured by DLW. The other 60 subjects will be studied twice, one month apart, to test the reproducibility of the measures.
