消防是一项身心俱疲的活动。真实的实时监测消防员的疲劳状态，对于提高消防工作效率，预防消防事故的发生，减少因注意力不集中而造成的人为失误，更好地进行职业安全管理具有重要意义。一般来说，安全管理是基于现场领导的经验和每个团队消防员的自我判断。我们进行了两项测试，即多步增量负荷测试和修改的20 m往返跑测试，并提出了一个表明代谢状态从有氧向无氧转变的指标。该指数可以基于心电图信息（RR间隔）的频率分析非侵入性地获取。该指标对负荷强度反应灵敏，并与其他生理指标如阈、血乳酸等有较好的相关性。我们根据上述两项试验的结果确定了“继续活动”的警戒阈值，并通过在其他试验中的应用验证了这些发现的有效性。一个是恒定负载间隔测试，另一个是模拟消防活动的标准化培训测试。结果表明，警戒阈值可以用来估计消防员心肺功能的负荷程度。通过将本研究中提出的客观信息添加到活跃在消防现场的消防员自己感受到的主观信息中，可以预期消防活动的进一步安全改进。
Firefighting is a physically and mentally stressful activity. It is important to monitor the fatigue state of firefighters in real time in order to get a better occupational safety management though improving the efficiency of firefighting activities, preventing incidents and accidents during firefighting, and reducing human errors due to losing concentration. In general, safety management is based on the experience of the on-site leader and self-judgment of each team firefighter. We conducted two tests, a multi-step incremental load test and modified 20 m shuttle run test, and proposed an index which shows that metabolic state changed from aerobic to anaerobic. This index can be acquired noninvasively based on a frequency analysis of electrocardiographic information (RR interval). This index sensitively responds to load intensity and shows good correlation with other physiological information such as ventilatory threshold and blood lactic acid. We determined the alert threshold for “continuation of activity” based on results obtained in above mentioned two tests and verified the validity of these findings through application in other tests. One is constant load interval test and another is the standardised training test which simulates firefighting activities. It was confirmed that the alert threshold, which means the deviation from the aerobic metabolic state, can be used to estimate the degree of load on cardiopulmonary function of firefighters. By adding objective information proposed in this research to the subjective information felt by the firefighters themselves active at the firefighting site, further safety improvement of the firefighting activities can be expected.
