METHOD OF DETERMINING PERSONALIZED DAILY ENERGY EXPENDITURES BY PULSEOMETRY Russian patent published in 2019 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to labor physiology, namely to methods of determining personalized daily energy expenditures of a person, and can be used in medical institutions, medical-sports dispensaries, sports and health-improving complexes. Disclosed is a method of determining personalized daily power consumption by pulseometry, comprising collecting data to obtain calibration dependence of energy expenditures on heart rate, monitoring heart rate (HR) with a wrist pulse meter and converting the obtained HR data into power consumption using a calibration curve formula. To obtain a calibration curve, data collection is carried out three times for a period of not more than 10 days, heart rate monitoring is carried out using a wrist pulse meter with 24-hour recording function and storing digital data in a file suitable for mathematical processing, and obtained data are converted into energy consumption by formula sigmoid EC=ECR+k1/(1+exp(k2×(HR-k3))), where EC – energy costs, kcal/min, ECR – energy costs at rest, kcal/min, HR – heart rate min^-1, k1, k2, k3 are numerical parameters reflecting individual physiological indices of a human body.

EFFECT: invention provides higher accuracy of determination of energy expenditures during a day, as well as provides the possibility of their assessment at each stage of labor activity and rest during the day and for ranges of low and high HR to obtain physiologically justified values.
