目的:消防员与狗一起工作,以支持他们寻找受害者的活动。处理狗的消防员应该有更高的急性肌肉疼痛,更多的绊脚石,和疲劳。这项研究旨在验证人工狗对消防员的心理生理和肌肉反应的影响,以及模拟搜索活动中的失衡数量。
方法:样品由10只犬科动物组成,其特征是质量(92.57±9.66kg),高度(1.78±0.06m),年龄(37.8±2.1岁),和服务年限(9.5±4.6年),在2个实验条件(狗条件和对照条件)下进行搜索活动。模拟搜索活动包括从搜索开始到隐藏假受害者的地点之间预定义的2.5公里远足。心脏代谢变量,疼痛程度,运动前和运动后测量肌肉性能(时间因子)。徒步旅行期间遭受的失衡数量也得到了量化。
结果:ANOVA数据表明与握力有关的相互作用(条件×时间)(P<0.05)。在狗的搜索后活动中,握力降低,与前活性相比,它增加了对照(-12.3%对9.2%)。此外,颈部疼痛和不适的程度,树干,髋关节区域较高(P<0.05)。在狗和控制条件下,有25和05不平衡,分别,在徒步旅行中。在狗或对照组的垂直跳跃表现和心血管反应的实验条件之间没有显着差异。
结论:这项研究的结果突出表明,与消防员相处的狗增加了滑倒的数量,trips,方向突然改变,身体失去平衡,伴随着手握力量的降低,增加颈部的急性疼痛,树干,和臀部。这些发现可能有助于支持减轻伤害和优化消防部门和其他cinotechnic部门犬类操作员的绩效的策略。
OBJECTIVE: Firefighters work with dogs as support for their search activities for victims. Firefighters who handle dogs supposedly have higher acute muscle pain, more stumbling, and fatigue. This study aimed to verify the influence of a mantrailing dog on the firefighter\'s psychophysiological and muscular responses and the number of imbalances in a simulated activity of searching for people.
METHODS: The sample consisted of 10 canine operators characterized by mass (92.57 ± 9.66 kg), height (1.78 ± 0.06 m), age (37.8 ± 2.1 yr), and length of service (9.5 ± 4.6 yr), who performed a search activity under 2 experimental conditions (dog condition and control condition). The simulated search activity consisted of a predefined hike of 2.5 km between the beginning of a search and the place where the sham victim was hidden. Cardiometabolic variables, pain level, and muscular performance were measured pre and postactivity (time factor). The number of imbalances suffered during hiking was also quantified.
RESULTS: ANOVA data indicated interactions (condition × time) related to handgrip strength (P < 0.05). Handgrip strength was reduced in the postsearch activity with the dog, and it increased the control when compared to the preactivity (-12.3% versus +9.2%). Also, the level of pain and discomfort in the neck, trunk, and hip regions was higher with dogs (P < 0.05). Under the dog and control conditions, there were 25 and 05 imbalances, respectively, during the hike. There were no significant differences between the experimental conditions for vertical jump performance and cardiovascular responses either with dog or control.
CONCLUSIONS: The findings of this study highlight that a mantrailing dog with the firefighter increased the number of slips, trips, sudden changes in direction, and loss of body balance, accompanied by a reduction in handgrip strength, and increased acute pain in the neck, trunk, and hip. These findings may contribute to support strategies for mitigating injuries and optimizing the performance of canine operators in the fire department and other units cinotechnic.
