Recurring sequences of multimodal non-verbal and verbal communication during a human psycho-social stress test: A temporal pattern analysis
2020
Abstract Background The Trier Social Stress Test (TSST) is a widely used protocol to study human psycho-social stress responses. Quantitative reports of non-verbal behaviors have been carried out by means of the Ethological Coding System for Interviews (ECSI). However, no data have described whether and how non-verbal and verbal behaviors take part in the composition of multimodal sequences of communication during the test. Method Five non-verbal ECSI categories and four verbal behaviors related with communication were included in the Ethogram. A focal sampling was employed to ensure a high temporal resolution of the behavioral annotation. T-Pattern Analysis was employed to detect statistic…
Chronic and Acute Effects on Skin Temperature from a Sport Consisting of Repetitive Impacts from Hitting a Ball with the Hands.
2022
Valencian handball consists in hitting the ball with the hands and it may contribute to injury development on the hands. This study aimed to analyze skin temperature asymmetries and recovery after a cold stress test (CST) in professional players of Valencian handball before and after a competition. Thirteen professional athletes and a control group of ten physically active participants were measured. For both groups, infrared images were taken at the baseline condition; later they underwent a thermal stress test (pressing for 2 min with the palm of the hand on a metal plate) and then recovery images were taken. In athletes, the images were also taken after their competition. Athletes at bas…
Association of cardio-pulmonary stress test parameters and heart rate recovery in obese subjects with or without type II diabetes
2016
Background and Objectives: Heart rate recovery at first (HRR-I) and second (HRR-II) minute after exercise is accurate in estimating autonomic nervous system balance, and has been related to risk of cardiovascular events. Our aim was to determine independent predictors of HRR collected during standard cardio-pulmonary stress test (CPT) in a group of overweight/obese subjects without (N=14) and with type 2 diabetes (N=19), as compared to a sample (N=15) of healthy sedentary subjects. Methods: A graded exercise test on treadmill was performed. Oxygen uptake at rest and at peak exercise (VO2max), as well as respiratory exchange ratio at peak exercise was collected. Linear and logistic regressio…
The effect of restrained eating on acute stress-induced food intake in people with obesity
2021
Abstract Restrained eating, defined as a form of intense dieting or restrictive food intake of specific macronutrients or types of food with sporadic episodes of overeating, results in an increased risk of overweight and obesity. Acute stress situations cause irregular eating patterns and are connected to restrained eating. Therefore, the present study investigates the effect of high/low restrained eating on eating behavior in people with obesity after standardized acute stress induction as well as resting condition. Fifty men and women with obesity (BMI: 33.62 ± 3.93 kg/m2) were categorized into high restrained eaters (HRE) and low restrained eaters (LRE). The total energy intake was measu…
Optimism and pessimism are related to different components of the stress response in healthy older people.
2015
Some personality traits have key importance for health because they can affect the maintenance and evolution of different disorders with a high prevalence in older people, including stress pathologies and diseases. In this study we investigated how two relevant personality traits, optimism and pessimism, affect the psychophysiological response of 72 healthy participants (55 to 76 years old) exposed to either a psychosocial stress task (Trier Social Stress Test, TSST) or a control task; salivary cortisol, heart rate (HR) and situational appraisal were measured. Our results showed that optimism was related to faster cortisol recovery after exposure to stress. Pessimism was not related to the …
Burnout, associated comorbidities and coping strategies in French community pharmacies—BOP study: A nationwide cross-sectional study
2016
International audience; Background: work-related stress and burnout syndromes are unfortunately common comorbidities found in health professionals. However, burnout syndrome has only been partly and episodically assessed for community pharmacists whereas these professionals are exposed to patients’ demands and difficulties every day. Prevalence of burnout, associated comorbidities and coping strategies were assessed in pharmacy teams (pharmacists and pharmacy technicians) in French community pharmacies.Methods: This online survey was performed by emails sent to all French community pharmacies over 3 months. The survey assessed the prevalence of burnout (Maslach Burnout Inventory—MBI—questio…
Acute stress affects free recall and recognition of pictures differently depending on age and sex.
2015
Little is known about age differences in the effects of stress on memory retrieval. Our aim was to perform an in-depth examination of acute psychosocial stress effects on memory retrieval, depending on age and sex. For this purpose, data from 52 older subjects (27 men and 25 women) were reanalyzed along with data from a novel group of 50 young subjects (26 men and 24 women). Participants were exposed to an acute psychosocial stress task (Trier Social Stress Test) or a control task. After the experimental manipulation, the retrieval of positive, negative and neutral pictures learned the previous day was tested. As expected, there was a significant response to the exposure to the stress task,…
The impact of cortisol reactivity to acute stress on memory: Sex differences in middle-aged people
2010
Stress has been identified as a main factor involved in the cognitive changes that occur during the aging process. This study investigated sex differences in the relationship between the magnitude of the acute stress-induced salivary cortisol response and memory performance among middle-aged people. To this end, 16 men and 16 women (aged 54-72 years) were exposed to the Trier Social Stress Test and a control condition in a crossover design. Afterwards their memory performance was measured using a standardized memory test (Rey's Auditory Verbal Learning Test). Only among women, there was an acute impact of stress on memory performance and a significant relationship between a higher cortisol …
Effects of psychosocial stress on the hormonal and affective response in children with dyslexia
2019
Abstract Introduction Research on stress and dyslexia has mainly focused on chronic and contextual stress caused by the school environment. Our goal was to test individual differences in the hypothalamic-pituitary-adrenal (HPA) axis reactivity of dyslexic and non-dyslexic children and the related emotional manifestations associated with exposure to a psychosocial stressor. Methods Eighty-one children (11–14 years old; 38 dyslexic) were exposed to the Trier Social Stress Test adapted to children or to a control condition. The salivary cortisol response, anxiety, and mood were measured before and after the stress. Results Dyslexic children did not show the expected cortisol response, as the h…
Testosterone/cortisol ratio in response to acute stress: a possible marker of risk for marital violence.
2013
Testosterone to cortisol (T/C) ratios could be associated with feelings and expression of anger as high testosterone and low cortisol levels indicate a predisposition to violence. The basal T/C ratio has recently been proposed as a marker for proneness to social aggression; so far, however, only its value as an indicator of state anger or violence has been investigated. Given this, we aimed to establish whether the T/C ratio response to acute stress was a specific psychobiological feature in individuals with a history of violence, namely, perpetrators of intimate partner violence (IPV). T/C ratio and anger responses were compared in men jailed for IPV and controls using the Trier Social Str…
