| Outline of Final Research Achievements |
It has been shown that individuals with higher resting heart rate variability (HRV) have higher capacity of regulation over stress. This study examined a hypothesis that manipulation to enhance HRV might facilitate stress regulation capacity. Participants conducted the biofeedback training of respiration which can enhance HRV, and then conducted an acute stress task (mental arithmetic task with time pressure) where psychological and physiological stress reactivity was evaluated.
An experimental group who conducted two trials of 10 min. biofeedback training showed robust enhancement of power of low frequency component of HRV. Further, the experimental group showed reduction of stress reactivity in subjective rating of stress and an inflammatory cytokine, compared to a control group who did not conduct the biofeedback training. Thus it was certificated that enhancement of HRV was effective to facilitate stress regulation capacity.
