About this study
Official title: Assessment of Human Locomotion and Energy Expenditure Using Global Positioning Satellite and Accelerometry
The aim of the study is to validate the association of the GPS and accelerometer tools in order to assess the humain locomotion during exercises.
The hypotheses are:
- GPS and accelerometer together can assess the human locomotion
- GPS and accelerometer together can assess the energy expenditure during exercises
Read the detailed description
The assessment of the physical activity (PA) and the energy expenditure (EE) is very important to estimate the morbi-mortality. However, each of these tools has its advantages and disadvantages but none of them provides a measure of all components dimensions that characterize the associated PA and EE. The current scientific prospects for measurement of PA tend to associate several measuring devices. To date, these perspectives are facilitated by technological developments and miniaturization of various devices. Thus, the purpose of the study is to evaluate wether GPS associated with accelerometer are able to assess the humain locomotion and energy expenditure during exercises.

What is being measured
The primary outcome is the main question the study is designed to answer.
Defining optimal analysis parameter to accurately detect walking from stopping periods
Predefined walking protocols will be recorded and the subjects asked to follow recorded procedures.
Detection performance of walking and resting bouts (expressed by the percentage accuracy in the detection of walking and resting bouts actually performed) for: i) GPS alone; ii) Accelerometer alone; iii) both GPS and accelerometer
Measured: up to 1 week
Secondary outcomes (1)
Defining optimal analysis parameter to accurately detect speed and distance of periods of walking
Predefined walking protocols will be recorded and the subjects asked to follow recorded procedures at a defined walking pace.
Accuracy of speed and distance estimations (expressed by the typical error of estimate and the coefficient of variation) from: i) GPS alone; ii) Accelerometer alone; iii) both GPS and accelerometer.
Measured: up to 1 week
