音乐放松缓解作业人员应激情绪的研究

目的研究音乐放松对缓解特殊作业人员应激情绪的作用。方法在参加神舟十一号载人航天飞行任务的工作人员中招募志愿者15人,任务过程中和任务后各进行1次音乐放松。在音乐放松前、后采集主观体验指标和唾液皮质醇指标,音乐放松过程中采集心率变异性指标。结果音乐放松后,心率(heart rate,HR)降低(71.08±7.97)beats/min vs.(68.15±7.05)beats/min)],相邻NN间期差的均方根(root mean square of successive differences,RMSSD)升高(29.15±13.27)ms vs.(36.86±14.22ms)],高频功率(high frequency,HF)升高(219.05±180.39)ms~2vs.(329.01±235.87)ms],差异均有统计学意义(P0.05)。唾液皮质醇(cortisol)水平降低(6.50±1.04)ng/mL vs.(6.01±0.65)ng/mL],差异接近显著(P=0.079)。结论音乐放松对于缓解作业人员应激情绪具有积极作用,对于下丘脑-垂体-肾上腺(hypothalamo-pituitary-adrenal,HPA)轴和自主神经系统均有影响。

Effects of Music Relaxation on Personnel's Stress and Emotion

Objective To explore the effects of music relaxation on personnel's stress and emotion.Methods Fifteen subjects were recruited from the staffs who were involved in the SZ-11 manned spaceflight.The experiment was performed 2 times:the first one was in the mission and the other one was after the mission.All subjects' saliva cortisol sample and subjective questionnaire were obtained before and after the music relaxation experience,and heart rate variability(HRV) data were collected during the music relaxation experience.Results The heart rate (HR) was lower (71.08 ±7.97) beats/min vs.(68.15 ±7.05) beats/min],root mean square of successive differences (RMSSD) was higher (29.15 ± 13.27) ms vs.(36.86 ± 14.22)ms],the high frequency (HF) increased (219.05 ± 180.39) ms2 vs.(329.01 ± 235.87) ms2],and the differences were statistically significant (P ＜ 0.05).Saliva cortisol level decreased (6.50 ± 1.04) ng/mL vs.(6.01 ±0.65) ng/mL],the differences were nearly statistically significant (P =0.079).Conclusion Music relaxation can affect the function of hypothalamo-pituitary-adrenal (HPA) axis and the autonomic nervous system,and it is of positive influence on stress and emotion of personnel who participate special work.
