The Contrastive Analysis of Three Models About Human Energy Expenditure

Abstract

Objective Through the studies on contrastive analysis of three models, find a scientific and simple method to evaluate energy expenditure. Methods Six healthy young men are selected as the test objects. The tests were conducted until the test objects’ heart rate reached 90% of the maximum or they could not insist on testing. Data including VO2, VCO2, HR, and ACC were measured. The energy expenditure models put forward by Keytel and Sasaki were adopted to measure energy expenditure based on heart rate and accelerometer. Results There is no significant difference between the energy expenditure based on heart rate and IC method under the high exercise intensity (P > 0.05) and the energy expenditure measured according to acceleration and IC method (P > 0.05) under the low exercise intensity. In other conditions, there are significant differences between the two methods. Conclusions Energy expenditure is affected by many factors. Based on test purposes, researchers should adopt many physical parameters to evaluate and reduce the influence of single factor on the test results.
