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.
