About this Research Topic
Heart rate variability (HRV), the variation in the time intervals between adjacent heartbeats, has become one of the most popular psychophysiological measures in recent times. Its use by researchers and practitioners spans across many different fields, encompassing medicine, the health sciences, psychology, sport sciences, and other disciplines. Its growing popularity is perhaps due to its desirable characteristics: non-invasive, low cost, and recording feasibility across settings. Above all, HRV is capable to index the activity of the vagus nerve regulating cardiac functioning, cardiac vagal activity, which is linked to many crucial functions in self-regulation, adaptation, and health. In this Research Topic, we will welcome papers aiming to showcase novel applications of HRV. Specifically, we welcome innovative ideas regarding the measurement, analyses, and theoretical conceptualization of HRV. Similarly, ground-breaking interventions aiming at HRV enhancement will be particularly welcomed.
This Research Topic will showcase novel approaches, the current richness, and diversity of HRV research. Building on recent controversies and lessons learned about HRV measurement and interpretation, we aim to identify the challenges of the upcoming 10 years, helping to delineate the current limitations of HRV research. Further, we aim to take this opportunity to bring together the main actors of HRV applications research in the spirit of the first Task Force in 1996 that undoubtedly marked the HRV field and its expansion.
