摘要:
目的 探讨应激状态下，新兵训练倦怠与血压、心率之间的关系。
方 法 对新兵采用问卷调查与试验相结合的方法进行研究，问卷为新兵训练倦怠自评问卷，以收缩压（SBP）、舒张压（DBP）、心率（HR）为观察指标，采用相关及线性回归分析的方法分析训练倦怠与血压、心率的关系。
结果 ①新兵任务期血压和心率值高于基线期、结束期（
P =0.000）。训练倦怠高分组任务期和结束期SBP、DBP、HR值高于低分组（P <0.01）。②身心耗竭得分与任务期HR值呈负相关（r =-0.139，P =0.005）；训练倦怠总分及身心耗竭、训练疏离得分均与任务期-基线期HR波动值、任务期-结束期HR波动值呈负相关（P <0.05或0.01）。③线性回归分析显示，任务期和结束期HR对身心耗竭得分的影响有统计学意义（t =-4.137、2.519，P =0.000、0.012）；任务期－结束期HR对训练倦怠总分的影响有统计学意义（t =-2.637，P =0.009）。结论 新兵的血压、心率在受到心理应激时反应强烈，身心耗竭、训练疏离与心率变化有一定关联，加强身心耗竭、训练疏离的调控有利于其心率的控制。
Abstract:Objective To assess the relationship of training burnout with blood pressure and heart rate in new recruits under stress.
Method Using questionnaire survey and experimental research, the recruits were asked to complete Self-Assessment Training Burnout Questionnaire and measured for systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Correlation analysis and linear regression model were used to assess the relationship of blood pressure with heart rate, and training burnout.
Result ① The blood pressure and heart rate of the recruits during task period were significantly higher than those during baseline period and end period (
P =0.000). The SBP, DBP, and HR values of the high training burnout group were significantly higher than those of the low training burnout group during task period and end period (P <0.01). ② Physical and mental exhaustion scores were negatively correlated with HR values during task period (r =-0.139,P =0.005). The total scores of training burnout and the scores of physical and mental exhaustion and training alienation were negatively correlated with the fluctuations of HR during task-baseline period and task-end period (P <0.05 or 0.01). ③ According to the linear regression analysis, during task period and end period, HR had a statistically significant impact on physical and mental exhaustion scores (t =-4.137, 2.519;P =0.000, 0.012). During task-end period, HR had a statistically significant impact on the total scores of training burnout (t =-2.637,P =0.009).Conclusion The blood pressure and heart rate of recruits strongly respond to psychological stress. Physical and mental exhaustion and training alienation both have an effect on heart rate response. It is beneficial to the control of heart rate by strengthening the regulation of physical and mental exhaustion and training alienation.
