24 hours monitoring the trend of some physical parameters in children during sport, school, and leisure activities through the latest wearable technology system generation. An exploratory approach.

This research aimed to monitor the trend of electrocardiographic activity and establish the quality and quantity of the physical activity performed for an entire day (24 hours) during a week by a group of children using, an innovative, wearable, and comfortable device the K-Sport-Shirt (Patented by K-Sport Universal, Montelabbate, PU, Italy); it’s one of the first approaches all over the world with textile sensors to have obtained CEMED certification; an informatize shirt equipped with a positioning system, receiving and sending data from/to four satellites systems, normally is only the GPS, plus three triaxial inertial sensors both interconnected by a sensor fusion firmware. The positioning device is called K-AI the shirt contains some electrocardiographic sensors with medical official validation too. Twelve children between the ages of 6 and 13 belongings to two sub-elite football sport clubs Fossombrone Academy, and Montecchio Academy, from Italy, participated in the study. The main purpose was to monitor, heart rate responses to establish internal load values in different situations on the whole day such as school, sports, and leisure time activities (using electronics devices too), as well as during sleep, which in any case will be developed and deepened in a second-time investigation to evaluate pre-sleep activities and their influence on the sleep itself. In addition, during the sporting activity, in this case, football, the commitment due to the training work proposed for the measurement of the external load was detected using the parameters of the distance traveled, travel speed, and others considered qualifying for the surveys carried out, thanks to the cited K-AI device.
