Heart Rate Variability (HRV) Biofeedback and Athletic Performance: Expected physiological, psychological and performance outcomes

In this last part of my introductory series on HRV Biofeedback, I will provide an overview of the main outcomes of HRV Biofeedback interventions, in terms of performance changes as well as physiological or psychological changes. I will first report on early explorations, then move towards higher-quality studies and finally cover recent attempts to investigate HRV Biofeedback interventions in more applied and practical settings.
