About this study
Official title: A Smartphone Application to Evaluate Energy Expenditure and Duration of Moderate-intensity Activities in Free-living Conditions (eMouve 2)
The aim of this study was to validate 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.
Read the detailed description
There is a growing interest in evaluating physical activity and energy expenditure (EE) to provide feedback to the user. The use of mass-market sensors such as accelerometers offers a promising solution for the general public due to the growing smartphone market over the last decade.
Thus, the proposed EE estimation function has been created using accelerometry data collected from 10 volunteers equipped with a smartphone and two research sensors (Armband and Actiheart) used to estimate EE during several controlled activities. The research sensors' data serves as reference during the creation and evaluation of the proposed function.
It has been evaluated with data of 6 other volunteers in free-living conditions in the previous eMouve project.
eMouve2 consists in acquiring more data from 24 new volunteers in order to validate the function in free-living conditions.
This EE estimation function using the smartphone technology is dedicated to light- and moderate-intensity activities, and we believe it can be a new way to help people controlling their daily physical activity level.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Energy expenditure estimationDevice
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.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Accelerometry (time frame: about 17Hz (duration: about 12 hours)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
