Heart-rate variability biofeedback (BFB) effectively reduces anticipatory stress and enhances perceived performance. This proactive stress-coping method improves cardiac coherence during stressful anticipation periods.
Area of Science:
- Psychophysiology
- Stress Research
- Biofeedback Interventions
Background:
- Anticipating stressful situations triggers psychophysiological reactions.
- Characterizing and modulating anticipatory stress responses remain key challenges.
- Heart-rate variability biofeedback (BFB) offers a potential method for managing anticipatory stress.
Purpose of the Study:
- To characterize the anticipation period of stress.
- To evaluate the effectiveness of BFB in managing anticipatory stress.
- To assess the impact of BFB on cognitive performance post-stress anticipation.
Main Methods:
- Utilized the Trier Social Anticipatory Stress (TSAS) protocol to induce stress.
- Compared BFB intervention group (stress + bfb) with a control group (stress + video).
- Measured heart-rate variability (cardiac coherence, SDNN, RMSSD) and psychological state during anticipation.
Main Results:
- BFB intervention group showed significantly higher cardiac coherence than the stress + video group.
- Participants in the BFB group reported reduced psychological stress.
- BFB intervention led to increased perceived performance levels post-anticipation.
Conclusions:
- BFB is a viable proactive stress-coping strategy.
- The TSAS protocol effectively induces and allows examination of anticipatory stress.
- BFB interventions can mitigate negative psychophysiological responses to anticipated stress.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
