摘要：

【摘要】目的 研究生物反馈放松训练对职业紧张刑警心率变异性（HRV）的影响。方法 使用职业健康量表（OSI-R）筛选我市中、高度紧张反应（即个人紧张反应分量表T分60以上）刑警538人，随机抽取52名为研究对象。运用心理素质训练评估系统分别于静息、应激、放松状态下测定其肌电水平（EMG）、心率（HR）、HRV时域指标（SDNN、 RMSSD、pNN50）和频域指标（VLF、LF、HF、TP、LF/HF），并进行比较分析。结果 应激状态EMG（29.27±9.79）高于静息（14.13±8.00）及放松（10.02±6.74）状态（P < 0.05），静息与放松状态差异无统计学差异（P > 0.05）；SDNN、RMSSD、VLF、 HF和TP均是应激状态最低，放松状态最高（P < 0.05）；LF、LF/HF均是应激状态最高，放松状态最低（P < 0.05）。结论 放松训练可以改善职业紧张刑警自主神经系统的功能活性状况。

Abstract:

[Abstract] Objective  To observe the influence of relaxation training on the heart rate variability of occupational stress in criminal police officers. Methods  The Occupational Stress Inventory-revised (OSI-R) were employed to test the stress response of all the criminal policemen in our city. Five hundred and thirty-eight ones were moderate and high levels of stress(personal stress subscales, T score was above 60), and 52 from them were randomly selected as the research object of this study. The electromyography (EMG), heart rate (HR) and heart rate variability (HRV) consisting of the time-domain (SDNN, RMSSD and PNN50) and frequency-domain (VLF, LF, HF, TP and LF/HF) were detected in resting, stress and relaxed states in objects. Results  The value of EMG was higher under the stress condition (29.27±9.79) than that of the resting status (14.13±8.00) and relaxed status (10.02±6.74, P < 0.05), and no statistical difference between resting and relaxed status (P > 0.05). There were the lowest values of SDNN, RMSSD, VLF, HF and TP in stress status and the highest values of them in relaxed status respectively (P < 0.05). However, the values of LF and LF/HF were the highest under stress status, and which were the lowest in relaxed status (P < 0.05). Conclusion  Relaxation training could improve the functional activities of the autonomic nervous system in occupational stress criminal policemen.
