Vagal tone and depression in adolescents: Protective factors during parent-adolescent interaction
Vagal tone, an index of emotion regulation, is related to a number of mental health outcomes in youth, including depressive risk and symptomology. The current study examined the role that vagal tone, as measured by respiratory sinus arrhythmia (RSA) at rest and during emotionally relevant …

Parenting and internalizing symptoms in early adolescence: The moderating role of vagal tone
The present study investigated baseline respiratory sinus arrhythmia (RSA) as moderator of the prospective association between parenting and internalizing symptoms among a group of typically developing adolescents across the transition to middle school. At Time 1 (5th grade; spring before middle …

Effects of Aquatic Therapy on Vagal Tone and Social Behaviors in Individuals with Autism Spectrum Disorder
… study evaluated the effect of aquatic therapy on vagal tone as well as behavior in participants with ASD (n=32) and without ASD (n=32). Measures consisted of social, swimming, emotional and cognitive tasks. Following the aquatic intervention participants with ASD demonstrated a statistically …

The Role of Cardiac Vagal Tone in Prediction of Individual Differences in Attention and Emotion Processing After Sleep Restriction
… laden visual stimuli were examined. The role of vagal tone, indexed by Respiratory Sinus Arrhythmia (RSA), was examined as a trait-like individual difference variable for prediction of vulnerability to sleep loss. Healthy, good sleepers between the ages of 17-30 were recruited from a university …

Individual differences in affect and vagal tone in response to moderate- and high-intensity interval exercise: A preliminary model
… engagement. Purpose. To examine affective and vagal tone reactivity to and recovery from an acute bout of moderate-intensity (MIIE) and high-intensity interval exercise (HIIE), and to consider how individual differences (e.g., personality, biological dispositions) influence these responses. …

Marital Harmony and Conflict: Linkages to Infants' Emotional Regulation, Cardiac Vagal Tone, and Developmental Status at Six- and Nine-Months of Age
This study examined the linkages between marital harmony and conflict and infants' emotional and physiological regulation abilities and developmental status at six- and nine-months of age. Participants included 93 first-time mothers and their infants (43 males, 50 females) from a Mountain West …

THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
… of isothermic water increased both the cardiac vagal tone as indicated by increased RMSSD (mean 23.95 ± 20.50 msec increase, p<0.05) and sympathetic activity shown by increased QTc interval (mean 9.86 ± 8.59 msec increase, p< 0.05) during the first 40 minutes post-ingestion. These effects were …

An Evaluation of the Efficacy of Selected Nonpharmacologic Pain Interventions in Infants
… studied. Pain measures were duration of cry, vagal tone, and salivary cortisol. MANOVA revealed that the sucrose coated pacifier group cried significantly less than the water moistened pacifier and control groups. ANCOVA demonstrated significant covariation of birth weight with cortisol and …

Individual Differences in Physiology, Behavior, and Temperament Over the First 15 Months of Life
… (ICQ), and a questionnaire of developmental milestones. Heart period, heart period variability, and an index of neural control of the heart by the vagus (i.e., vagal tone, V,) were analyzed from the cardiorespiratory data.

The Psychophysiology of Maladaptive Perfectionism and Mindfulness Meditation: An Investigation Using Heart Rate Variability
Heart rate variability (HRV) is a vagal nerve-mediated biomarker of cardiac function used to investigate chronic illness, psychopathology, stress and, more recently, attention-regulation processes such as meditation. This study investigated HRV in relation to maladaptive perfectionism (MP), a …

Vascular and Neuro-Inflammatory Modulation Following Resistance Training in Young African American and White Men
… physiology. Resistance training improved vagal tone, reduced C-reactive protein, reduced central (i.e. aortic and carotid) blood pressure and improved microvacular endothelial function in both African American and white men. Resistance training had no effect on arterial stiffness or wave …

Resistance training for patients with chronic heart failure
… strain gauge venous occlusion plethysmography. Vagal tone was assessed using heart rate variability. No medical complications arose during training or testing sessions. There were increases in upper body strength (42 ± 8; P = 0.037) and increases in lower body strength (22 ± 9%, P = 0.044) and …

CARDIOVASCULAR AUTONOMIC IMPAIRMENT IN GBA PARKINSONIAN PATIENTS
… variability was performed to assess sympatho-vagal balance and vagal tone in both supine and standing positions. Additionally, 123I-MIBG myocardial single-photon emission CT was used to evaluate postganglionic sympathetic nerve terminals. Results: A total of 34 GBA carriers and 33 I-PD …

What Makes a Mind-Minded Mother?
… rate variability (HF-HRV), an index of cardiac vagal tone, predicted interactional MM in independent samples of mothers with infants and toddlers. Previous correlates of interactional MM and resting HF-HRV were also taken into account. Results indicated that resting HF-HRV did not relate to …

Cardiac, ventilatory and metabolic responses of two ecologically distinct species of fish to waterborne cyanide
… in the trout was due initially to increased vagal tone but later due to the direct effect of cyanide on the heart. Hyperventilation in the trout persisted throughout the exposure period, although the rate and amplitude fluctuated and was variable between individual fish. During the last hour …
