Abstract：Objective To investigate the impact of heart rate variability biofeedback(HRVB)training on the sub-health and heart rate variability(HRV)of junior army commanders,so as to provide a basis for improving their mental health and psychological-physical capabilities.Methods A total of 47 junior army commanders were selected and random-ly divided into control group(n=22,who did not receive HRBV training)and experimental group(n=25,who received HRVB training)by two-factor mixed experimental design(group × training sessions).The sub-health measurement scale and HRV assessments were employed to evaluate the sub-health psychological and physiological conditions of the ar-my commanders before and after the experiments.Results After HRVB training,the sub-health status of the experimen-tal group improved significantly compared to that before training(P＜0.05);the HRV indicators including standard devi-ation of all normal to normal intervals,(SDNN),very low frequency(VLF),total power(TP)in the control group showed a decreasing trend,and the difference was statistically significant(all P＜0.05),while the experimental group maintained a relatively stable state with no significant differences(P＞0.05);after 3 weeks of training,the HRV SDNN,root mean square of the successive normal to normal intervals difference(rMSSD),VLF,TP in the experimental group were significantly higher than those in the control group(all P＜0.05).Conclusion HRVB training can effectively im-prove the sub-health status and psycho-physiological abilities of junior army commanders.
