目的 通过电脑游戏模拟应激条件下27名潜水员和30名普通岸勤人员心率及心率变异性的分析,探讨潜水员心脏自主神经活动的特点.方法 实验采用电脑游戏作为应激诱发材料,在被试操作的同时记录心率和心率变异性指标.结果 (1)模拟应激条件潜水员的恐惧、厌恶和紧张体验与普通岸勤人员比较差异有统计学意义(P＜0.05或P＜0.01).(2)2组被试者在3个阶段的平均心率(heart rate variability,HRP)主效应显著[(F(2,110)=67.700,P＜0.01)],低频功率(LF)主效应显著[(F(2,110) =20.774,P＜0.01)],高频功率(HF)主效应显著[(F(2,110) =5.647,P＜0.05)],LF/HF 主效应显著[(F(2,110) =6.101,P＜0.05)],低频校正值(LFnu)主效应显著[(F(2,110) =6.184,P＜0.05)],高频校正值(HFnu)主效应显著[(F(2,110) =6.735,P＜0.05)].(3)组间比较差异无统计学意义.组别与阶段之间在LF/HF[(F(2,110) =4.285,P＜0.05)]有显著交互作用.结论 (1)模拟应激条件下潜水员心脏自主神经活动的特点是预期阶段交感神经张力的上升,副交感神经张力下降.应对阶段交感神经张力和副交感神经张力同时下降,但副交感神经张力下降的幅度较小.(2)潜水员迷走神经的功能相对较强,可下调负性情绪体验的强度,同时迷走神经功能不协调也影响负性情绪体验的敏感性.
目的 通過電腦遊戲模擬應激條件下27名潛水員和30名普通岸勤人員心率及心率變異性的分析,探討潛水員心髒自主神經活動的特點.方法 實驗採用電腦遊戲作為應激誘髮材料,在被試操作的同時記錄心率和心率變異性指標.結果 (1)模擬應激條件潛水員的恐懼、厭噁和緊張體驗與普通岸勤人員比較差異有統計學意義(P＜0.05或P＜0.01).(2)2組被試者在3箇階段的平均心率(heart rate variability,HRP)主效應顯著[(F(2,110)=67.700,P＜0.01)],低頻功率(LF)主效應顯著[(F(2,110) =20.774,P＜0.01)],高頻功率(HF)主效應顯著[(F(2,110) =5.647,P＜0.05)],LF/HF 主效應顯著[(F(2,110) =6.101,P＜0.05)],低頻校正值(LFnu)主效應顯著[(F(2,110) =6.184,P＜0.05)],高頻校正值(HFnu)主效應顯著[(F(2,110) =6.735,P＜0.05)].(3)組間比較差異無統計學意義.組彆與階段之間在LF/HF[(F(2,110) =4.285,P＜0.05)]有顯著交互作用.結論 (1)模擬應激條件下潛水員心髒自主神經活動的特點是預期階段交感神經張力的上升,副交感神經張力下降.應對階段交感神經張力和副交感神經張力同時下降,但副交感神經張力下降的幅度較小.(2)潛水員迷走神經的功能相對較彊,可下調負性情緒體驗的彊度,同時迷走神經功能不協調也影響負性情緒體驗的敏感性.

Objective To explore the features of cardiac autonomic nervous activity of divers by analyzing the heart rate and heart rate variability of 27 divers and 30 ordinary naval personnel ashore.Methods Subjects'heart rate and heart rate variability were recorded under stressors of computer games.Results (1) Under stressful conditions,divers experienced significantly less terror and strain than ordinary naval personnel ashore.(2) Main effects on heart rate variability (HRP) at the 3 stages could be significantly seen in the subjects of the 2 groups [F(2,110) =67.700,P ＜ 0.01)],and the main effect on LF was obviously marked [F(2,110) =20.774,P ＜ 0.01)],the main effect on HF was also marked [(F (2,110) =5.647,P ＜0.05)],the main effects on LF/HF could be significantly noted [(F(2,110) =6.101,P ＜ 0.05)],and the main effect on Lfnu was significant [(F (2,110) =6.184,P ＜ 0.05)] and the main effect of Hfnu was also significant [(F (2,110) =6.735,P ＜ 0.05)].(3) No significant differences could be seen,when comparisons were made between the groups,and interactions were quite obvious in LF/HF between the 2 groups and at different stages [F (2,110) =4.285,P ＜ 0.05].Conclusions (1) Under simulated stressful conditions,cardiac autonomic nervous activity of divers had the following features:sympathetic nerve strain increased at the anticipation period,and parasympathetic nerve strain decreased.However,at the coping period,both sympathetic nerve and parasympathetic nerve strain all decreased,with the parasympathetie nerve strain decreased only with a small margin.(2) Better vagus nerve function in divers could down-regulate the intensity of negative emotion and at the same time incoordination of vagus nerve also had some effect on sensitivity of negative emotion.
