消防员在实时火灾训练演变后表现出显著的生理压力. 压力和免疫反应的生物标志物,包括α-amylase,皮质醇和分泌IgA,在训练后立即升高.
科学领域:
- 职业健康 职业健康 职业健康
- 生理学 生理学 生理学
- 免疫学 免疫学 免疫学
背景情况:
- 消防工作涉及到强烈的身体和心理需求.
- 了解生理应激反应对于消防员的福祉至关重要.
研究的目的:
- 评估消防员在现场火灾训练演化 (LFTE) 期间的急性生理应激反应.
主要方法:
- 七十六名消防员接受了LFTE.
- 唾液样本是在LFTE之前,之后立即和30分钟后收集的.
- 分析包括α-氨基酶 (AA),皮质醇 (CORT) 和分泌免疫球蛋白-A (SIgA).
主要成果:
- 与训练前水平相比,AA,CORT和SIgA度在LFTE后立即显著增加 (P<0.001).
- 在LFTE后30分钟仍然存在高水平,尽管一些生物标志物略有下降.
- 效应大小表明,在演化后立即出现压力生物标志物的中等到大增加.
结论:
- 现场火灾训练演变诱导了消防员显著的急性应激反应.
- 这种反应涉及下丘脑-垂体-上腺轴,交感-上腺髓系统和免疫系统的激活.
- 需要进一步的研究来将这些压力生物标志物与绩效和长期健康风险联系起来.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Hypothalamic-Pituitary Axis
