Study Description

Brief Summary:

Monitoring of a person's physical status is a key point for maintaining of "healthy life". Wearable devices provide a unique possibility for real-time monitoring. This study aims to estimate the accuracy of Spectrophon Dehydration Body Monitor (DBM) incorporated in smartwatch Samsung Gear S2 and sport band Samsung Gear Fit2 by comparing data obtained by DBM with the total weight lost during exertion.
