MOTIONPOD (TM) Validation and Calibration Study

In this study we propose 1) to develop a new multisensor monitoring system associating a tri-axial accelerometer and a magnetometer to measure physical activity in free-living adults, 2) to perform its calibration and assess its validity in a series of activity tasks in comparison with the measure of energy expenditure by indirect calorimetry as the criterion measure, and with existing physical activity monitors (cardiofrequencemetry and accelerometers used either alone or in combination). Briefly the subjects will perform a series of standardized activity tasks of different intensities and a 30-min free physical activity period while wearing 6 MOTIONPOD(TM) and different commercial activity monitors. Physical activity energy expenditure will be measured using a metabolic gas analyser.

Data of the 30 first subjects will be used to develop new algorithms to identify the different activity tasks and to estimate the related energy expenditures. Data of the following 30 subjects will be used to validate the MotionPOD(TM) against indirect calorimetry and existing physical activity monitors

Treatment and study plan

MOTIONPOD (TM) measures

Device

It is a study with a single arm. The MOTIONPOD TM measures are compared with simultaneous estimations obtained with the criteria measure (indirect calorimeter) and with existing activity monitors (heart rate monitor POLAR; different accelerometers - rT3 et Actigraph GT3X-, Actiheart, Sensewear Pro2 Armband) After physical fitness evaluation, different activity monitors are set up and the subjects perform a series of standardised activity tasks of different intensities, and well as a 30-min free activity period. Physical activity energy expenditure is measured at the end of each task using a metabolic gas analyser

Primary outcomes

  1. Estimation by the MOTIONPODTM of the physical activity energy expenditure (PAEE) during a 30-min free activity period in comparison with the measure of PAEE by indirect calorimetry

    Time frame: 30 minutes

Secondary outcomes

  1. Identification and classification of the tasks performed during a 30-min free activity period

    Time frame: 30 minutes

  2. Estimation by the MOTIONPODTM of the physical activity energy expenditure during each of the tasks performed during the experiment in comparison with 1) indirect calorimetry, 2) existing commercially activity monitors

    Time frame: During three hours

  3. Intensity classification by the MOTIONPODTM of the physical activity energy expenditure during each of the tasks performed during the experiment and during the 30-min free activity period.

    Time frame: During three hours

    Intensity classification by the MOTIONPODTM of the physical activity energy expenditure during each of the tasks performed during the experiment and during the 30-min free activity period in comparison with 1) indirect calorimetry, 2) existing commercially activity monitors
