The Relational Mind in Couple Therapy : A Bateson-Inspired View of Human Life as an Embodied Stream
2018
Research on human intersubjectivity has found that humans participate in a dialogue throughout their life, and that this is manifested not only via language, but also nonverbally, with the entire body. Such an understanding of human life has brought into focus some basic systemic ideas concerning the human relational mind. For Gregory Bateson, the mind works as a system, formed from components that are in continuous interaction with each other. In our Relational Mind research project, we followed twelve couple therapy processes involving two therapists per session, looking at the ways in which the four participants attuned to each other with their bodies, including their autonomic nervous s…
Heart and Skeletal Muscles: Linked by Autonomic Nervous System.
2019
Background Resting sympathetic hyperactivity and impaired parasympathetic reactivation after exercise have been described in patients with heart failure (HF). However, the association of these autonomic changes in patients with HF and sarcopenia is unknown. Objective The aim of this study was to evaluate the impact of autonomic modulation on sarcopenia in male patients with HF. Methods We enrolled 116 male patients with HF and left ventricular ejection fraction < 40%. All patients underwent a maximal cardiopulmonary exercise testing. Maximal heart rate was recorded and delta heart rate recovery (∆HRR) was assessed at 1st and 2nd minutes after exercise. Muscle sympathetic nerve activity (MSN…
Effects of HRV-Guided vs. Predetermined Block Training on Performance, HRV and Serum Hormones
2017
AbstractThe aim of this study was to compare heart rate variability -guided (HRVG) and predetermined (PD) block periodization of high intensity aerobic training (HIT). Endurance performance, neuromuscular performance, heart rate variability (HRV) and serum hormone concentrations were measured before, in the middle and after the 8-week training period in 24 endurance trained males. Both groups improved significantly maximal treadmill velocity (Vmax) (p<0.001) and 3000 m running performance (HRVG; p<0.001 and PD; p=0.001). The relative changes in Vmax and countermovement jump were significantly greater in HRVG (p<0.05). Nocturnal heart rate decreased in both groups (p<0.01), but H…
Individual Endurance Training Prescription with Heart Rate Variability
2016
Introduction: Measures of HR variability (HRV) have shown potential to be of use in training prescription. Purpose: The aim of this study was to investigate the effectiveness of using HRV in endurance training prescription. Methods: Forty recreational endurance runners were divided into the HRV-guided experimental training group (EXP) and traditional predefined training group (TRAD). After a 4-wk preparation training period, TRAD trained according to a predefined training program including two to three moderate- (MOD) and high-intensity training (HIT) sessions per week during an 8-wk intensive training period. The timing of MOD and HIT sessions in EXP was based on HRV, measured every mornin…
Recovery from sauna bathing favorably modulates cardiac autonomic nervous system
2019
Objective: Sauna bathing is becoming a common activity in many countries and it has been linked to favorable health outcomes. However, there is limited data on the heart rate (HR) and heart rate variability (HRV) responses to an acute sauna exposure. Design: We conducted a single-group, longitudinal study utilizing a pre-post design to examine acute effects of sauna bathing on the autonomic nervous system as reflected by HRV. A total of 93 participants (mean [SD] age: 52.0 [8.8] years, 53.8% males) with cardiovascular risk factors were exposed to a single sauna session (duration: 30 min; temperature: 73 °C; humidity: 10–20%) and data on HRV variables were collected before, during and after …
Associations of physical activity, sedentary time, and cardiorespiratory fitness with heart rate variability in 6- to 9-year-old children: the PANIC …
2019
Purpose. To study the associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with heart rate variability (HRV) in children. Methods. The participants were a population sample of 377 children aged 6–9 years (49% boys). ST, light PA (LPA), moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA), and PA energy expenditure (PAEE) were assessed using a combined heart rate and movement sensor, maximal power output per kilograms of lean body mass as a measure of CRF by maximal cycle ergometer exercise test, and HRV variables (SDNN, RMSSD, LF, and HF) using 5 min resting electrocardiography. Data were analysed by linear regression adjusted …
Coactivation of Autonomic and Central Nervous Systems During Processing of Socially Relevant Information in Autism Spectrum Disorder: A Systematic Re…
2023
AbstractBody-brain interaction provides a novel approach to understand neurodevelopmental conditions such as autism spectrum disorder (ASD). In this systematic review, we analyse the empirical evidence regarding coexisting differences in autonomic (ANS) and central nervous system (CNS) responses to social stimuli between individuals with ASD and typically developing individuals. Moreover, we review evidence of deviations in body-brain interaction during processing of socially relevant information in ASD. We conducted systematic literature searches in PubMed, Medline, PsychInfo, PsychArticles, and Cinahl databases (until 12.1.2022). Studies were included if individuals with ASD were compared…
Sympathetic nervous system synchrony: An exploratory study of its relationship with the therapeutic alliance and outcome in couple therapy.
2019
In previous research, we found that sympathetic nervous system synchrony, measured via electrodermal activity (EDA), occurs between participants at the start of couple therapy. The aim now was to test whether this synchrony changes during the therapy process, and how any changes may be related to clients' and therapists' evaluations of the working alliance, and the outcome of therapy. Twelve different couple therapy processes were analyzed (24 clients, plus 10 therapists, working in pairs; hence, 4 persons per session) using EDA concordance indices and questionnaires (Outcome Rating Scale, Session Rating Scale, and Clinical Outcomes in Routine Evaluation-Outcome Measure). EDA synchrony betw…
Vuoristovaelluksen vaikutus autonomisen hermoston toimintaan : adaptaation etenemisen seuranta sykevälivaihtelumuuttujien ja satelliittipaikannuksen …
2014
Vuoristoympäristö on ihmisen fysiologialle yksi epäsuosiollisimmista olosuhteista maapallolla. Vuoristo-olosuhteiden fysikaaliset ominaispiirteet, hypobaarinen hypoksia sekä kylmä ilmasto, asettavat monenlaisia vaatimuksia ihmisen elimistön toimintakyvyn ylläpitämiseksi. Akuutti vuoristotauti ilmenee henkilöillä, joilla vuoristoon sopeutuminen ja kompensoivat toimet eivät ole edistyneet onnistuneesti. Hoitamattomana tila voi edetä hengenvaaralliseen aivo- tai keuhkoödeemaan. Viimeaikaisissa tutkimuksissa on raportoitu lupaavia tuloksia yksilöiden välisistä keskushermoston sopeutumismallieroista vuoristotaudin diagnosoinnissa. Tämän tutkimuksen tarkoituksena oli selvittää löytyykö ortostaatt…
Hiljaisten hetkien funktioita vaikeassa pariterapiaistunnossa
2016
Tämän tutkimuksen tarkoituksena oli tuoda kuvailevaa tietoa hiljaisten hetkien merkityksistä ja funktioista vaikeassa pariterapiaistunnossa. Monimenetelmäinen tutkimuksemme yhdisti terapiaistunnon elementtejä usealta tasolta; näkyvä vuorovaikutus ja siihen liittyvät hiljaiset hetket, emootioiden virittymisestä kertovat autonomisen hermoston reaktiot (ihon sähkönjohtavuus ja hengitys) autenttisessa terapiatilanteessa sekä jälkihaastattelujen kommentit ja terapiaistunnon arviointilomakkeet. Tunnistimme istunnosta kuusi hiljaisten hetkien luokkaa: 1) vetäytyminen, 2) pohdintatauko, 3) uuden suunnan tai lähestymistavan hakeminen, 4) informaation kerääminen ja asioiden syy-seuraussuhteiden selve…
