Measurement and analysis of heart rate variability in a population of professional firefighters based on heart rate (RR) recording. Assessment based on a smoke chamber test in correlation with age, length of service, body mass index.
The smoke chamber test for the officers of the State Fire Service (SFS) is aimed at improving the skills and techniques of working in special clothing and in a respiratory protection set (RPS) under high psychophysical burden. The study was divided into 3 stages: 1. measurement of parameters at rest - sitting position for 5 min, 2. measurement of parameters during the firefighter's activity, effort related to the training path and the test in the smoke chamber, indefinite time (different for each firefighter), 3. measurement of parameters at rest after exercise - sitting position for 5 min. Each firefighter included in the study had fitted onto his chest a Polar H10 band with a sensor (size XXL) that measures parameters HR, HRV (sensor connected via Bluetooth to an application on the phone of a person controlling the test).
The study involved 96 firefighters aged 19-45 (Mean 27.9; SD 7.4), with 1-19 years of service (Mean 5.2; SD 4.6). The study included 75 firefighters who completed the entire activity and their results were recorded completely in a way that allowed for analysis and interpretation. Results of 17 firefighters were selected (parameters describing HRV changes was carried out, which are important from the authors' experience: RMSSD, HF ms, DFA α1).
The presence of excessive body weight did not affect HR parameters, which may be related to the limited possibilities of using the BMI index among people with high muscle mass. Longer work experience has a health-promoting effect on heart rate values through increased adaptation of the circulatory system to increased effort and stress. HRV parameter and ANS activity have a wide range of clinical applications, in addition to monitoring health status in the course of diseases, ANS activity can be analyzed in correlation with occupational risk factors.
基于心率（RR）记录，对职业消防人员进行心率变异性测量和分析。评估基于与年龄、服役年限、体重指数相关的烟雾室测试。
国家消防局（SFS）官员的烟雾室测试旨在提高在特殊服装和呼吸保护装置（RPS）下工作的技能和技术，以应对高心理生理负荷。该研究分为 3 个阶段：1. 休息时参数测量-坐 5 分钟，2. 消防员活动期间参数测量，与训练路径和烟雾室测试相关的努力，不定时（每个消防员不同），3. 运动后休息时参数测量-坐 5 分钟。每位参与研究的消防员都在胸部佩戴了带有传感器的 Polar H10 带（XXL 尺寸），该传感器通过蓝牙连接到测试人员手机上的应用程序来测量 HR、HRV（传感器）参数。
该研究涉及 96 名年龄在 19-45 岁（平均 27.9；标准差 7.4）的消防员，服役年限为 1-19 年（平均 5.2；标准差 4.6）。该研究包括 75 名完成整个活动的消防员，他们的结果以允许分析和解释的方式完整记录。选择了 17 名消防员的结果（进行了描述 HRV 变化的参数，这些参数是作者经验中很重要的：RMSSD、HF ms、DFA α1）。
超重并没有影响 HR 参数，这可能与高肌肉质量人群中 BMI 指数的使用有限有关。更长的工作经验通过增加循环系统对增加的努力和压力的适应，对心率值产生健康促进作用。HRV 参数和自主神经系统活动具有广泛的临床应用，除了在疾病过程中监测健康状况外，还可以分析自主神经系统活动与职业危险因素的相关性。
