Rapid acquisition method of resting metabolic rate based on sliding window heart rate signal analysis

Abstract

The invention relates to a rapid acquisition method of resting metabolic rate based on sliding window heart rate signal analysis. The method comprises the steps that under a rest state of a human body, oxygen consumption VO2 (2) and carbon dioxide emission VCO2 (3) are measured while heart rate signals (1) are monitored, and simultaneously a novel sliding time window analysis method (4) is adoptedto analyze the heart rate signals; a testing end is dynamically identified according to two characteristics of derivative summation Df of the heart rate signals in the sliding time window and a coefficient of variation CV, and effective testing data of the oxygen consumption VO2(2) and the carbon dioxide emission VCO2(3) is extracted for calculating the resting metabolic rate. The method is usedfor calculating the resting metabolic rate of the human body, determination of the testing end can be conducted according to personalized heart rate signals, and the method has the advantages of beingaccurate in measuring resulTS and short in measuring time.

Description

technical field [0001] The invention relates to the field of resting metabolic rate measurement, in particular to a resting metabolic rate method based on respiratory exchange parameter measurement and heart rate signal monitoring. Background technique [0002] Malnutrition is defined as a nutritional state in which excess, deficiency or imbalance of energy or nutrients has a deleterious effect on human tissue, body shape, function or clinical outcome, including undernutrition and overnutrition. Malnutrition is widespread in both inpatient and general health settings. About 40% of hospitalized patients suffer from malnutrition; in the field of public health, overweight and obesity are typical overnutrition-type malnutrition. According to the "Report on Nutrition and Chronic Disease Status of Chinese Residents" released by the National Health and Family Planning Commission in 2015, my country Among adults, 30.1% were overweight and 11.9% were obese, an increase of 7.3% and 4....
