UNASSIGNED: The purpose of this study was to profile HRV during a PTG SC. Six (n = 6) qualified male police officers attempted a 36-hour PTG selection course held at an Australian state facility.
UNASSIGNED: HRV was obtained from Equivitaltrademark EQ02 + LifeMonitor bioharnesses. The selection course consisted of physically demanding events with minimal sleep (approx. 45 mins). Only one candidate completed the full selection course; whose results are reported here.
UNASSIGNED: A visual time-series of 384 consecutive 5 min HRV analyses was generated. Contextual analysis was applied to appreciate HRV changes between SC serials. HRV decline occurred during the planning of a navigation exercise and a pack march. Increases in HRV were observed throughout the pack march exercise and rest period.
UNASSIGNED: This case study demonstrates the potential utility for selection personnel to obtain additional insight into candidate responses to various occupational challenges throughout an SC. Information provided by HRV monitoring may support leadership decisions when evaluating personnel holistically. For example, the ability to continue occupational task execution even while experiencing potential overstress (as measured by HRV) and after food and sleep deprivation is desirable. HRV may potentially inform stakeholders regarding overstress in PTG candidates.
目的:本研究的目的是分析PTGSC期间的HRV。六名(n=6)合格的男性警察试图在澳大利亚国家机构举行36小时的PTG选拔课程。
方法:从Equivital商标EQ02+LifeMonitor生物线束获得HRV。选择课程包括具有最少睡眠的身体要求的事件(大约。45分钟)。只有一名候选人完成了完整的选拔课程;其结果在此处报告。
结果:产生384个连续5分钟HRV分析的视觉时间序列。上下文分析用于了解SC序列之间的HRV变化。HRV下降发生在规划导航演习和行军时。在整个行军运动和休息期间观察到HRV的增加。
结论:本案例研究证明了甄选人员在整个SC中获得对候选人对各种职业挑战的反应的额外见解的潜在效用。HRV监控提供的信息可以在全面评估人员时支持领导决策。例如,即使在经历潜在的过度压力(通过HRV衡量)以及在食物和睡眠剥夺后仍能够继续执行职业任务的能力是可取的。HRV可能会告知利益相关者有关PTG候选人的过度压力。
