Neuromuscular and hormonal adaptations to resistance training : special effects of time of day of training

2009

The majority of the processes in human physiology and behaviour exhibit daily variation. Neuromuscular performance has been repeatedly shown to be lower in the morning hours compared to the rest of the day. However, the scientific data available provide somewhat conflicting results on the origin and mechanisms of diurnal variation in maximum strength and power. In addition, very limited scientific evidence exists as to whether this diurnal variation can be diminished by time-of-day-specific resistance training.The present study was designed to obtain more information on the mechanisms behind both diurnal variation in muscle strength and power, and the mechanisms behind adaptations to time-o…

Sympathetic nervous system synchrony between participants of couple therapy

2017

Synchrony, or the moment-by-moment coordination between people in social situations, has been connected with increased liking and rapport. However, this type of synchrony is an underexplored area with regard to autonomic nervous system activity. The purpose of this research was to study physiological synchrony between participants in couple therapy by focusing on the sympathetic nervous system (SNS), which reflects arousal and emotional reactions. The data comprised 12 couple therapy cases (24 clients, 10 therapists) participating in the Relational Mind in Events of Change in Multiactor Therapeutic Dialogues (2013-2016) research project. Electrodermal activity (EDA) and heart rate were reco…

Teachers’ situational physiological stress and affect

2023

Since teaching is a demanding and stressful profession, the study of teachers’ physiological stress in the classroom setting is an emerging field. In cross-sectional studies self-reported stress and affect are related, but less is known about the intraindividual relations between situational physiological stress and corresponding positive and negative affect. The aim of our study was to investigate the associations between situational physiological stress (six salivary cortisol samples per day) and self-reported situational affect (Positive and Negative Affect Schedule four times a day) among 61 Finnish primary school teachers over two workdays. We present a novel multilevel structural equa…

Trait emotional intelligence and its associations with subjective and physiological well-being

2018

The present thesis examined the association between trait emotional intelligence (EI) and well-being (subjective well-being [SWB] and physiological well-being) among Japanese participants (eldercare nurses and undergraduate university students). This research had four primary goals: First, to identify profiles of trait EI and to investigate their association with SWB (Study I); second, to examine the role of trait EI in the process of SWB (Study II); third, to investigate the association of trait EI with psychological state and physiological well-being in a laboratory-based stress induction condition (Study III); and fourth, to investigate the association of trait EI with affect and physiol…

Associations Between Adolescents' Subjectively Experienced Emotions and Psychophysiological Reactions in Achievement Situations

2022

This study investigated associations of early adolescents' (N=190, median age = 12) subjectively experienced emotions and psychophysiological reactions in achievement situations. Self-reported questions assessed adolescents' experienced emotions. Additionally, adolescents' autonomic nervous system (ANS) reactions were recorded; skin-conductance response (SCR) and heart rate (HR) were used to measure sympathetic nervous system activity, and heart rate variability (HRV) was used to measure parasympathetic nervous system activity. The between-person-level results of multilevel modeling showed that increased HR was associated with higher levels of hope and fear and that decreased SCR was associ…

Short-term responses of Rana arvalis tadpoles to pH and predator stress: adaptive divergence in behavioural and physiological plasticity?

2022

Environmental stress is a major driver of ecological and evolutionary processes in nature. To cope with stress, organisms can adjust through phenotypic plasticity and/or adapt through genetic change. Here, we compared short-term behavioural (activity) and physiological (corticosterone levels, CORT) responses of Rana arvalis tadpoles from two divergent populations (acid origin, AOP, versus neutral origin, NOP) to acid and predator stress. Tadpoles were initially reared in benign conditions at pH 7 and then exposed to a combination of two pH (acid versus neutral) and two predator cue (predator cue versus no predator cue) treatments. We assessed behavioural activity within the first 15 min, an…
