Abstract：
The main goal of this study was to update the Finnish smoke-diving drill (FSDD) and to measure the physical strain of and recovery from the drill. Furthermore, the aim was to compare the physical strain of contract and professional firefighters and effect of floor materials. The associations between aerobic capacity and physical strain were also studied. The updates made included an added hose pull task and updating the equipment used. Heart rate (HR), oxygen consumption (V̇O2), and blood lactate concentration ([La-]) of 32 professional and 5 contract firefighters were measured before, during, and 10 and 30 min after the updated drill. The mean HR during the drill was 78% and V̇O2 59% of maximum. HR and [La-] had not recovered to baseline levels after 30-minute recovery period. Physical strain was higher among contract firefighters and [La-] accumulation on rough floor surfaces. Better aerobic capacity was associated with reduced physical strain.
The purpose of this study was to update the Finnish smoke-diving drill. This paper describes the process of updating the drill, and the experimental measurements regarding the metabolic demands of the updated drill. The updates made included adding a hose pull task and updating the equipment used during the drill.

摘要：
这项研究的主要目标是更新芬兰烟雾潜水钻机（FSDD），并测量钻机的物理应变和恢复情况。此外，目的是比较合同和专业消防员的身体压力和地板材料的影响。还研究了有氧能力与物理应变之间的关系。所做的更新包括增加的软管拉动任务和更新使用的设备。心率(HR)耗氧量（V²O2），之前测量了32名专业消防员和5名合同消防员的血乳酸浓度（[La-]），during,以及更新后的10分钟和30分钟。演习期间的平均HR为78％，V²O2为最大值的59％。在30分钟恢复期后,HR和[La-]没有恢复到基线水平。合同消防员的物理压力更高，并且[La-]在粗糙的地板表面上积累。更好的有氧能力与降低的物理应变有关。
这项研究的目的是更新芬兰的烟雾潜水演习。本文介绍了钻头的更新过程,以及关于更新钻头的代谢需求的实验测量。所做的更新包括添加软管拉动任务和更新钻孔期间使用的设备。
