Drawing on psycho-physiological research emphasizing the importance of facilitating the emotion-cognition or heartbrain interaction through self-regulation techniques, the present study aimed at investigating the efficacy of heart rate variability (HRV) on heart-brain coherence through self-regulation techniques suggested by Institute of HeartMath. Sixty-three Iranian university students and hi...

This study examined the effect of an asynchronous heart rate variability biofeedback (HRV-BFBasync) protocol on national-level adolescent swimmers’ cognitive appraisals and recovery-stress states during a six-week ecological training period. A polynomial mixed-effects multilevel regression analysis approach was used with 27 swimmers randomly assigned to intervention group (n = 14) control 13). ...

Heart rate variability biofeedback (HRV-BF) is frequently used for stress management. Recently, virtual reality technology has gained attention delivery, promising higher immersion, motivation, and than classical screens. However, the effects of different technologies breathing techniques are not yet understood. In this study, 107 healthy participants completed a session in one four conditions:...

We developed a playful biofeedback system using a wearable device and modular interactive tiles. In this approach we suppose that patients could regulate exercise intensity on t heir own through biofeedback. We propose biofeedback play system called “bioToys” based on exercise with the modular interactive tiles. The system consists of a wearable device that measures heart-pulse via ear-mounted ...
