  • 运动生理学 运动生理学
  • 职业健康 职业健康 职业健康
  • 运动科学 运动科学 运动科学

背景情况:

  • 消防涉及艰苦的体力活动,需要专门的培训,以准备火场灭火任务 (FST).
  • 电路训练 (CT) 是消防员训练的潜在方法,但其在复制FST需求中的有效性需要评估.

研究的目的:

  • 在职业消防员中,将单次电路训练 (CT和CTW) 的心脏代谢和感知力度与火场抑制任务 (FST) 进行比较.

主要方法:

  • 23名消防员完成了三次测试:FST (全装七项职业任务),加权CT (CTW,18.9kg背心) 和未加权CT.
  • 测量包括相对心率 (%HRmax),血乳酸,反运动跳跃高度变化 (CMJ),手握强度变化 (DHG/NDHG),训练时间,感知劳动力评分 (RPE) 和工作相关性.

主要成果:

  • 与FST相比,CT和CTW引起的显著较低的%HRmax和更大的CMJ.
  • 对CT和CTW而言,训练时间显著缩短,而不是FST.
  • 尽管心血管反应有差异,CT和CTW对FST的感知劳动和代谢需求相似,尽管心血管反应不同.

结论:

  • 循环训练,无论是加重的还是没有加重的,都能为消防员提供类似的代谢和感知劳力的好处,如消防员的火场镇压任务.
  • CT和CTW不能完全复制FST的心血管需求,表明它们是有益的,但不能完全取代职业任务.
