Exploring Dynamics of Changes in Psychological Skills in the Development of Talented Athletes.

In this study we examined changes in a psychological skill set, defined as crucial for the growth of talented athletes, through repeated assessments of the six-factor Psychological Characteristics of Development Excellence Questionnaire (PCDEQ). In a first phase of this study, we built and evaluated a French adaptation of the PCDEQ: the PCDEQ-SV (18 items). After confirmatory factor analysis, Cronbach's alpha revealed that scales for its six factors ranged from very good to just below minimally acceptable as a model fit.

Predictors for Returning to Paid Work after Transient Ischemic Attack and Minor Ischemic Stroke.

This study aims to determine which factors within the first week after a first-ever transient ischemic attack (TIA) or minor ischemic stroke (MIS) are associated with stroke survivors’ ability to return to either partial or full time paid external work (RTpW). In this single-center prospective cohort study, we recruited 88 patients with first-ever TIA or MIS (NIHSS ≤ 5). Bivariate analyses were conducted between patients that did (RTpW) or did not return to paid work (noRTpW) within 7 days after stroke onset and at 3-months follow-up.

Understanding the Prevalence Rates of Interpersonal Violence Experienced by Young French-Speaking Swiss Athletes.

Facing the important methodological limitations of the instruments used for assessing the prevalence of interpersonal violence faced by young athletes, the aim of the present study was to propose and describe the use of a research instrument adapted to young and French-speaking athletes. In addition, by collecting preliminary data with a Swiss sample, we aimed to measure the different forms of interpersonal violence young athletes have experienced at least once during their sport practice. Our questionnaire was based on three existing questionnaires and adapted for a young audience.

The Effect of Obesity Class on the Energetics and Mechanics of Walking.

Higher mass-normalized net energy cost of walking (NetC) and mechanical pendular recovery are observed in obese compared to lean adults. This study aimed to investigate the effect of different classes of obesity on the energetics and mechanics of walking and to explore the relationships between body mass, NetC and gait mechanics by using principal component analysis (PCA). NetC and gait mechanics were computed in severely obese (SOG; = 18, BMI = 40.

Acute Effects of the Wim Hof Breathing Method on Repeated Sprint Ability: A Pilot Study.

The Wim Hof breathing method (WHBM) combines periods of hyperventilation (HV) followed by voluntary breath-holds (BH) at low lung volume. It has been increasingly adopted by coaches and their athletes to improve performance, but there was no published research on its effects. We determined the feasibility of implementing a single WHBM session before repeated sprinting performance and evaluated any acute ergogenic effects.

Hematological variables in recreational breath-hold divers: a longitudinal study.

Background: The influence of regular breath-hold training on hematological variables is not fully understood. We monitored hematological variables in breath-hold divers (BHDs) and active controls over a year expecting both breath-hold training and seasonal effects.

Methods: In 11 recreational BHDs (36±9 years, 177±8 cm, 72±9 kg) and 12 active controls (22±2 years, 174±8 cm, 70±13 kg) monthly blood samples were analyzed with the hematological module of WADA's athlete biological passport.

The Influence of Training Load on Hematological Athlete Biological Passport Variables in Elite Cyclists.

The hematological module of the Athlete Biological Passport (ABP) is used in elite sport for antidoping purposes. Its aim is to better target athletes for testing and to indirectly detect blood doping. The ABP allows to monitor hematological variations in athletes using selected primary blood biomarkers [hemoglobin concentration (Hb) and reticulocyte percentage (Ret%)] with an adaptive Bayesian model to set individual upper and lower limits.

Defense Mechanisms and Treatment Response in Depressed Inpatients.

The study investigated the extent to which defensive functioning and defense mechanisms predict clinically meaningful symptomatic improvement within brief psychodynamic psychotherapy for recurrent and chronic depression in an inpatient setting. Treatment response was defined as a reduction in symptom severity of 46% or higher from the baseline score on the Montgomery-Asberg Depression Rating Scale (MADRS). A subsample of 41 patients (19 responders and 22 non-responders) from an RCT was included.

[Incidence and predictors of peri-traumatic reactions in an Algerian population faced with COVID-19].

Objectives: This study explored two related questions: (1) the incidence of peri-traumatic distress and dissociation in a general Algerian population during the initial stages of the COVID-19 epidemic; (2) sociodemographic predictors of peri-traumatic reaction. The objective is to better understand the peri-traumatic experience in order to identify vulnerable people to whom psychological care could be offered.

Materials And Methods: An online descriptive survey containing three questionnaires, a demographic questionnaire, the questionnaire for peri-traumatic distress and the questionnaire for peri-traumatic dissociation experiences, was conducted using the snowball sampling technique to select 1374 Algerians.

Modulation of torque evoked by wide-pulse, high-frequency neuromuscular electrical stimulation and the potential implications for rehabilitation and training.

The effectiveness of neuromuscular electrical stimulation (NMES) for rehabilitation is proportional to the evoked torque. The progressive increase in torque (extra torque) that may develop in response to low intensity wide-pulse high-frequency (WPHF) NMES holds great promise for rehabilitation as it overcomes the main limitation of NMES, namely discomfort. WPHF NMES extra torque is thought to result from reflexively recruited motor units at the spinal level.

Reviewing the role of the environment in the talent development of a professional soccer club.

This two-part study examined the perceptions of talented Swiss soccer players about their talent development environment. The first study presented the translation and validation of the Talent Development Environment Questionnaire (TDEQ) into French using a recommended methodology for translating and culturally adapting questionnaires. Two hundred and three Swiss athletes (M = 16.

Does body position before and during blood sampling influence the Athlete Biological Passport variables?

Introduction: The Athlete's Biological Passport (ABP) is a tool for the indirect detection of blood doping. Guidelines from the World Anti-Doping Agency (WADA) require a 2 hours delay after any physical exercise, and to be seated for 10 minutes before collecting an ABP sample. This study investigated posture-related hematological variations with changes in body position during blood sampling.

Understanding Wellbeing Among College Music Students and Amateur Musicians in Western Switzerland.

Musical performance requires the ability to master a complex integration of highly specialized motor, cognitive, and perceptual skills developed over years of practice. It often means also being able to deal with considerable pressure within dynamic environments. Consequently, many musicians suffer from health-related problems and report a large number of physical and psychological complaints.

Executive control training does not generalize, even when associated with plastic changes in domain-general prefrontal areas.

How executive function training paradigms can be effectively designed to promote a transfer of the effects of interventions to untrained tasks remains unclear. Here, we tested the hypothesis that training with a complex task involving motor, perceptual and task-set control components would result in more transfer than training with a simple motor control task, because the Complex training would lead to more involvement-and in turn modification-of domain-general executive control networks. We compared performance and electrophysiological activity before and after 10 days of executive control training with the complex (n = 18) versus the simple task (n = 17).

Laboratory animal science course in Switzerland: participants' points of view and implications for organizers.

Switzerland has implemented a mandatory training in laboratory animal science since 1999; however a comprehensive assessment of its effects has never been undertaken so far. The results from the analysis of participants in the Swiss Federation of European Laboratory Animal Science Associations (FELASA) Category B compulsory courses in laboratory animal science run in 2010, 2012, 2014 and 2016 showed that the participants fully appreciated all elements of the course. The use of live animals during the course was supported and explained by six arguments characterized with cognitive, emotional and forward-looking factors.

Comparison of vitality states of finishers and withdrawers in trail running: An enactive and phenomenological perspective.

Studies on ultra-endurance suggest that during the races, athletes typically experience three vitality states (i.e., preservation, loss, and revival) at the phenomenological level.

Statistics in science and in society: From a state-of-the-art to a new research agenda.

Statistics occupies a prominent role in science and citizens' daily life. This article provides a state-of-the-art of the problems associated with statistics in science and in society, structured along the three paradigms defined by Bauer, Allum and Miller (2007). It explores in more detail medicine and public understanding of science on the one hand, and risks and surveys on the other.

Public perceptions of animal experimentation across Europe.

The goal of this article is to map out public perceptions of animal experimentation in 28 European countries. Postulating cross-cultural differences, this study mixes country-level variables (from the Eurostat database) and individual-level variables (from Eurobarometer Science and Technology 2010). It is shown that experimentation on animals such as mice is generally accepted in European countries, but perceptions are divided on dogs and monkeys.
