INTRODUCTION:Firefighters must work on roofs, in smoky places, and on slippery surfaces while using fire-protective clothing and a self-contained breathing apparatus (SCBA), together termed "fire-protective equipment" (FPE). The aim of this study was to investigate the effects of FPE on the functional and postural balance abilities of younger and older firefighters. METHODS:The subjects were professional firefighters in age groups 33-38 and 43-56 yr. Postural balance was tested with a force platform, and functional balance was measured during walking on a wooden plank with and without FPE. RESULTS:Wearing FPE significantly impaired both postural and functional balance. Postural balance with eyes closed was more negatively affected among the older subjects than the younger ones. Among the older subjects, the mean values for mediolateral velocity were 3.4 +/- 0.8 and 4.8 +/- 2.1 mm x s(-1) without and with FPE, respectively. The corresponding figures for velocity moment were 11.4 +/- 5.1 and 20.7 +/- 15.1 mm2 x s(-1). In the younger age group, the corresponding results were 3.6 +/- 1.0 and 4.1 +/- 1.4 mm x s(-1), in mediolateral velocity and 10.8 +/- 5.0 and 13.9 +/- 8.1 mm2 x s(-1) in velocity moment. SCBA was the most significant single piece of equipment to decrease performance in the functional balance test. CONCLUSIONS:These findings should be taken into consideration for preventing balance-related injuries in firefighting and rescue work, especially for older firefighters. Furthermore, balance should be considered in developing FPE and training protocols for firefighter fitness.

简介:消防员必须在屋顶,烟熏场所和湿滑的表面上工作,同时使用防火服和自给式呼吸器(SCBA),一起称为“防火设备”(FPE)。这项研究的目的是调查FPE对年轻和年长消防员的功能和姿势平衡能力的影响。
方法:受试者为33-38岁和43-56岁年龄段的专业消防员。使用力量平台测试姿势平衡,并在有或没有FPE的木板上行走时测量功能平衡。
结果:佩戴FPE显着损害姿势和功能平衡。闭着眼睛的姿势平衡在年长的受试者中比年轻的受试者受到的负面影响更大。在年龄较大的受试者中,不使用FPE和使用FPE时,中外侧速度的平均值分别为3.4 /-0.8和4.8 /-2.1 mm x s(-1)。速度力矩的相应数字为11.4 /-5.1和20.7 /-15.1 mm2 x s(-1)。在较年轻的年龄组中,对中侧速度的相应结果为3.6 /-1.0和4.1 /-1.4 mm x s(-1),速度矩为10.8 /-5.0和13.9 /-8.1 mm2 x s(-1)。 SCBA是降低功能平衡测试性能的最重要的单件设备。
结论:应考虑这些发现,以防止在消防和救援工作中,特别是对于年长的消防员,与平衡有关的伤害。此外,在制定消防人员的FPE和训练规程时应考虑平衡。
