The aim of this study was to measure aerobic demands of fire fighting activities including exercise in the heat.
Twenty-two experienced firefighters performed the Trondheim test simulating fire fighting tasks including work in the heat. Maximal oxygen uptake (VO2 max), heart rate (HR) and ventilation were recorded continuously. Data were compared with results obtained during a treadmill test during which the participants were dressed as smoke divers.
The participants completed physical parts of the Trondheim test in ˜12 min (range: 7.5-17.4). Time to complete the test was closely related to the participant's VO2 max. HR of ˜170 beats/min and pulmonary ventilation of ˜100 L/min were higher than at lactate threshold (LT) during laboratory tests. VO2 averaged over the test's physical part was 35 ± 7 ml/min/kg, which was at the same or below the level corresponding to the participants' LT. Physically fit participants completed the test faster than less fit participants. Slower and physically less fit participants consumed more air and used more oxygen than faster and physically more fit participants.
The Trondheim test is physically demanding; it distinguishes physically fit and less fit participants.
本研究旨在测量包括热环境下作业在内的消防活动的有氧运动需求。
22 名经验丰富的消防员进行了特隆赫姆测试，模拟了包括热环境下作业在内的消防任务。连续记录最大摄氧量（VO2 max）、心率（HR）和通气量。将结果与在跑步机上进行的测试结果进行比较，在该测试中，参与者穿着潜水服。
参与者在约 12 分钟内完成了特隆赫姆测试的体力部分（7.5-17.4 分钟）。完成测试的时间与参与者的 VO2 max 密切相关。HR 约为 170 次/分钟，肺通气量约为 100 L/分钟，高于实验室测试中的乳酸阈（LT）。测试体力部分的平均 VO2 为 35±7ml/min/kg，与参与者的 LT 水平相当或低于 LT 水平。体能较好的参与者比体能较差的参与者完成测试的速度更快。较慢和体能较差的参与者比较快和体能较好的参与者消耗更多的空气和氧气。
特隆赫姆测试对身体要求较高；它可以区分体能较好和较差的参与者。
