测量职业医学中的体力工作量是预防风险的基础。从心率（HR）间接测量总能量消耗和相对能量消耗（EE）被广泛使用，但从未得到验证。本研究的目的是验证这种HR估计的能量消耗（HREEE）方法对全身间接热量测定法。在量热室中连续记录52名成年男性和女性（19-65岁）的24小时HR和EE值。一个8小时的工作时间被保留，包括几个运动课程上的回旋运动强度高达65%的峰值摄氧量。HREEE的计算参考心脏储备。还计算了校正的HREEE（CHREEE），修改了心脏储备的最低值。这两个值进行了进一步比较，以建立的方法：灵活的HR方法，并使用一个三阶多项式的关系来估计总和相对EE. No显着差异时，发现总EE在量热室测量或估计从CHREEE的工作期间。在15%~ 65%的强度范围内，CHREEE与能量储备值呈良好的线性关系。当以CHREEE表示在15%至65%之间时，可以从HR记录中准确评估相对体力工作量，并且可以使用CHREEE方法准确估计EE。
Measuring physical workload in occupational medicine is fundamental for risk prevention. An indirect measurement of total and relative energy expenditure (EE) from heart rate (HR) is widely used but it has never been validated. The aim of this study was to validate this HR-estimated energy expenditure (HREEE) method against whole-body indirect calorimetry. Twenty-four-hour HR and EE values were recorded continuously in a calorimetric chambers for 52 adult males and females (19-65 years). An 8-h working period was retained, comprising several exercise sessions on a cycloergometer at intensities up to 65% of the peak rate of oxygen uptake. HREEE was calculated with reference to cardiac reserve. A corrected HREEE (CHREEE) was also calculated with a modification to the lowest value of cardiac reserve. Both values were further compared to established methods: the flex-HR method, and the use of a 3rd order polynomial relationship to estimate total and relative EE. No significant difference was found in total EE when measured in a calorimetric chamber or estimated from CHREEE for the working period. A perfect linear and identity relationship was found between CHREEE and energy reserve values for intensities ranging from 15% to 65%. Relative physical workload can be accurately assessed from HR recordings when expressed in CHREEE between 15% to 65%, and EE can be accurately estimated using the CHREEE method.
