Basal metabolic rate (BMR) is the main part of the total body energy expenditure. The value of BMR is individual and depends on a lot of factors. The goal of the research was to discover the influence of anthropometric parameters, age and gender, on changes of the BMR values.
A total of 177 individuals of Czech Caucasian origin from South Moravia (BMI 27.3 ± 7.88 kg/m) aged 18-55 (117 women, 60 men) were included in the study. Selected anthropometric characteristics were measured using a stadiometer (SECA 213) and bioelectrical impedance analysis (Inbody 230). BMR was measured by indirect calorimetry (Cortex Metalyzer 3B). The measured values were statistically evaluated by the regression analysis and least square method (LSM).
From the following results that the factors that influence the BMR value statistically significantly (p < 0.05) are: age, gender, body mass index, total body water, and percent of body fat.
Body fat and age have both an indirect impact on the basal metabolic rate of the Czech population in working age. However, BMI and the total body water were discovered to have a direct influence on the BMR.
基础代谢率（BMR）是全身能量消耗的主要部分。BMR的值因人而异，取决于许多因素。本研究的目的是探究人体测量参数、年龄和性别对BMR值变化的影响。
本研究纳入了177名来自摩拉维亚南部的捷克白种人（BMI 27.3±7.88 kg/m），年龄在18至55岁之间（女性117名，男性60名）。使用身高计（SECA 213）和生物电阻抗分析（Inbody 230）测量选定的人体测量特征。通过间接测热法（Cortex Metalyzer 3B）测量BMR。通过回归分析和最小二乘法（LSM）对测量值进行统计学评估。
从以下结果可知，对BMR值有统计学显著影响（p<0.05）的因素有：年龄、性别、体重指数、总体水含量和体脂百分比。
体脂和年龄对捷克劳动年龄人口的基础代谢率均有间接影响。然而，发现BMI和总体水含量对BMR有直接影响。
