Sleep-time physiological recovery is associated with eating habits in distressed working-age Finns with overweight: secondary analysis of a randomise…
2021
Background Association of physiological recovery with nutrition has scarcely been studied. We investigated whether physiological recovery during sleep relates to eating habits, i.e., eating behaviour and diet quality. Methods Cross-sectional baseline analysis of psychologically distressed adults with overweight (N = 252) participating in a lifestyle intervention study in three Finnish cities. Recovery measures were based on sleep-time heart rate variability (HRV) measured for 3 consecutive nights. Measures derived from HRV were 1) RMSSD (Root Mean Square of the Successive Differences) indicating the parasympathetic activation of the autonomic nervous system and 2) Stress Balance (SB) indica…

Syväoja, Heidi. 2010. Effects of exercise intensity on recovery of autonomic nervous system immediately after exercise and during sleep, and on subjective and objective sleep quality. Master´s thesis in Exercise Physiology. Department of Biology of Physical Activity. University of Jyväskylä, 90. The exercise can be considered as a one form of stress, because it induces marked changes in the autonomic regulation of heart rate (HR). During acute exercise, parasympathetic activity decreases and sympathetic activity increases. Parasympathetic activity declines a lot or even disappears, when the exercise intensity is high. After acute exercise cessation, fast changes occur in the cardiac functio…
Heart rate variability and self-control–A meta-analysis
2016
We read the commentary on our meta-analysis with great interest and we greatly appreciate that the authors developed suggestions for further research on heart rate variability (HRV) and self-control. While we mostly support these suggestions, we believe that it is necessary to clarify some points raised with respect to our meta-analysis. The first point brought up by the authors of the commentary is the focus of our meta-analysis on HRV instead of vagal tone and the inclusion of studies using the standard deviation of RR intervals (SDNN). They argue that only vagal tone and HRV metrics reflecting vagal tone are expected to be linked to self-control according to both the Neurovisceral Integr…
