Heart rate variability (HRV) refers to various methods of assessing the beat-to-beat variation
in the heart over time, in order to draw inference on the outflow of the autonomic nervous …

Heart rate variability (HRV) has been suggested as a biological correlate of self-control.
Whereas many studies found a relationship between HRV at rest and self-control, effect …

Pranayamic breathing, defined as a manipulation of breath movement, has been shown to
contribute to a physiologic response characterized by the presence of decreased oxygen …

Dyadic and collective activities requiring temporally coordinated action are likely to be
associated with cardiac and respiratory patterns that synchronize within and between …

The application of methods drawn from nonlinear and stochastic dynamics to the analysis of
cardiovascular time series is reviewed, with particular reference to the identification of …

The cardiorespiratory system exhibits oscillations from a range of sources. One of the most
studied oscillations is heart rate variability, which is thought to be beneficial and can serve …

Heart rate variability (HRV) indexes functioning of the vagus nerve, arguably the most
important nerve in the human body. The Neurovisceral Integration Model has provided a …

Aim: Present study was conducted to compare the effects of commonly practiced slow and
fast pranayama on perceived stress and cardiovascular functions in young health-care …

The body is, in essence, an ensemble of interacting systems with biorhythms nested at
multiple timescales. Traditionally, the focus in the study of body-brain interaction has been …

Recovering interaction of endogenous rhythms from observations is challenging, especially
if a mathematical model explaining the behaviour of the system is unknown. The decisive …
