最大心率预计值是评价工人负荷、疲劳与工作能力的重要指标。在一定的运动强度下与耗氧量、工作负荷程度呈线性关系。我们对１０１名井下矿工采用自行车功率计测定的方法，用ＢＨＬ６０００电脑心率测定仪测定其心率的变化以了解正常矿工心率变化的特点和规律，并提出建立中国煤矿工人的负荷与心率互换数学模型，进而作为评价体能负荷状态与疲劳水平的观察和评价指标之一。本试验结果推算矿工最大心率公式为１９４—年龄，建议今后在工作中以采用此数据为宜。
Estimated maximum heart rate is to evaluate the workload of workers, fatigue and ability to work an important indicator. In a certain intensity of exercise and oxygen consumption, the workload of a linear relationship. We use the method of bicycle power meter to measure 101 underground miners, measure the change of heart rate with BHL6000 computer heart rate monitor to understand the characteristics and regularity of heart rate change of normal miners, and put forward to establish the mathematical model of load and heart rate exchange of Chinese miners , And then as one of the indicators of evaluation and evaluation of physical load status and fatigue level. The test results to calculate the maximum heart rate formula for the 194-year miners, the proposed work in the future to adopt this data is appropriate.
