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…

Coping with competitive situations in humans

2005

The analysis of effects of competitive situations in our species may contribute to acquiring deeper knowledge about the effects of social stress and its relationship with different pathologies. The latest studies indicate that the neuroendocrine response to competition depends more on subjective factors related to the cognitive evaluation of the situation than on the outcome itself. Findings suggest that when subjects cope with a competition, they assess it in such a way that it activates a psychobiological coping response. The pattern of this response may correspond to a predominant active or passive coping strategy, the choice ultimately depending on factors such as the importance of the …

Trait Emotional Intelligence, Self-Reported Affect, and Salivary Alpha-Amylase on Working Days and a Non-Working Day

2017

This study examined the relationship between trait emotional intelligence (EI) and variation in psychological (positive affect: PA, negative affect: NA) and psychophysiological (salivary alpha-amylase: sAA) indicators among Japanese employees over 3 consecutive days (working day 1, non-working day, working day 2). The analyses revealed that higher trait EI was associated across the days with higher PA, but not with NA. Moreover, diurnal sAA levels were lower in the high trait EI group than in the low trait EI group on the intervening non-working day, and this difference between the EI groups continued to show a tendency to significance on working day 2. The results indicate that higher EI m…

High heart rate amplifies the risk of cardiovascular mortality associated with elevated uric acid.

2021

Abstract Aims  Whether the association between uric acid (UA) and cardiovascular disease is influenced by some facilitating factors is unclear. The aim of this study was to investigate whether the risk of cardiovascular mortality (CVM) associated with elevated UA was modulated by the level of resting heart rate (HR). Methods and results  Multivariable Cox analyses were made in 19 128 participants from the multicentre Uric acid Right for heArt Health study. During a median follow-up of 11.2 years, there were 1381 cases of CVM. In multivariable Cox models both UA and HR, either considered as continuous or categorical variables were independent predictors of CVM both improving risk discriminat…

Effects of exercise intensity on recovery of autonomic nervous system immediately after exercise and during sleep, and on subjective and objective sl…

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…
