Background: Obesity is one of the biggest drivers of preventable chronic diseases and healthcare costs in Worldwide. The most difficult aspect to take under consideration on the developing algorithms able to value the single session of kcal consumption in a single session of training are the hormonal factors.
Objective: In this study we done a preliminary study on the comparison of two different watch (that provide an estimate of kilocalories consumed with and without heart rate monitor) with an indirect calorimetry device. The aim of this study was to understand if the watch could be considered for health use and the variable that can influence the valuation accuracy of the kcal consumption during a training session on gym. Methods: In this preliminary study we analyzed the indicators that influence the daily energy expenditure and possible device able to track it, considering possible limits of application. Therefore, we analyzed the critical issue emerged to track each indicator. Results: From this preliminary study was possible to show that the accuracy of the device could have important difference case by case. More information have to be done to the customer to understand the accuracy of the different device able to detect the kcal consumption because it can modify the diet of not professional people. We had problem with the synchronization of health rate monitor and the watch with Bluetooth mode in room with computer or a lot of IT equipment. Discussion: This preliminary study showed that could be more vital signals to take under consideration developing algorithm for the daily kcal consumption. More study are need to understand way we have a difference of accuracy during a reliable test in healthy volunteers. Metabolism aspect could be taken under consideration starting from consideration related on weight and high of subject. Conclusion: The conclusion was not permitted to have the algorithm used to detect the kcal consumption so we did some preliminary test. From as analysis we show a not constant accuracy for the watch 1 and watch 2 vs. the indirect calorimetry. This suggest that some more variable have to be taken under consideration in developing of device, as suggested from the literature.
