Heatstroke Risk Informing System Using Wearable Perspiration Ratemeter: Human Experiments to Decide The Timing Point for Informing Heatstroke and to Evaluate The Validity of Wearable Appratus
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.45 Vol.45】
ABSTRACT
We constructed a wearable perspiration ratemeter to develop an informing system to users for the heatstroke risk. To decide the timing point for informing heatstroke risk, we conducted human experiments of 16 heathy subjects with the step up and down physical exercises In addition, a wearable self-identification and -information system of thirst response was developed with a smartphone. The blood and urine samples of the subjects was collected before and after the 30-min physical exercise. The concentrations of total protein（TP）， albumin（Alb）， and red blood cells（RBC） increased slightly with the exercise. In contrast, the concentrations of vasopressin in all subjects remarkably increased with exercise. Using the simultaneous recording of perspiration ratemeter, we decided that the timing point for informing heatstroke risk was to change from positive to negative on the second derivative of sweating curve. In almost subjects they identified their thirst response until several min after the informing for heatstroke risk. In conclusion, the wearable ratemeter and self-informing system of thirst response were suitable for informing system of heatstroke risk.
