Neurocircuitry of Personality Traits and Intent in Decision-Making.

Even though most personality features are moderately stable throughout life, changes can be observed, which influence one's behavioral patterns. A variety of subjective assessments can be performed to track these changes; however, the subjective characteristic of these assessments may lead to questions about intentions and values. The use of neuroimaging techniques may aid the investigation of personality traits through a more objective lens, overcoming the barriers imposed by confounders. Here, neurocircuits associated with changes in personality domains were investigated to address this issue. Cortical systems involved in traits such as extraversion and neuroticism were found to share multiple components, as did traits of agreeableness and conscientiousness, with these four features revolving around the activation and structural integrity of the medial prefrontal cortex (mPFC). The attribute of openness appears scattered throughout cortical and subcortical regions, being discussed here as a possible reflection of intent, at the same time modulating and being governed by other traits. Insights on how systems operate on personality may increase comprehension on factors acting on the evolution, development, and consolidation of personality traits through life, as in neurocognitive disorders.

Low prevalence of relative age effects in Luxembourg's male and female youth football.

The relative age effect (RAE) is a well-established phenomenon in football. However, while the majority of previous studies focussed on established football nations, it remains unclear if the constraint of a limited population of soccer players in smaller countries associated with less strict selection procedures may reduce the risk of RAE. This study aims to investigate the RAE in Luxembourg that follows an 'open-door' selection policy in youth football due to the limited pool of players. Birthdates from all licensed and actively playing Luxembourgish youth footballers including all players of the youth national teams (396 girls and 10981 boys) competing in the season 2018/2019 were analysed and categorised into birth quarters and semesters. To further investigate a performance dependence of the RAE in amateur leagues, success was determined based on the teams' rankings at the end of the season. Differences between observed and expected birthdate distributions were calculated across all licensed players and age groups, within the national teams, and for the top- and bottom-tier football teams using chi-square statistics. While a RAE was absent across all age groups (except U7), significant RAEs with high effect sizes were observed in the top-level and national teams. These findings contrast the substantial RAE effects in large football nations and suggest that open selection systems might reflect an environmental constraint that limit the prevalence of RAE in football. Further, this study indicates that a performance dependence of the RAE is not limited to high level football but already occurs on an amateur level.

Neurobiological Features of Posttraumatic Stress Disorder (PTSD) and Their Role in Understanding Adaptive Behavior and Stress Resilience.

Posttraumatic stress disorder (PTSD) has been impacting the functioning of a large number of people in military activities and victims of violence for many generations. However, investments in research aiming to understand the neurobiological aspects of the disorder started relatively late, around the last third of the 20th century. The development of neuroimaging methods has greatly supported further understanding of the structural and functional changes in the re-organization processes of brains with PTSD. This helps to better explain the severity and evolution of behavioral symptoms, and opens the possibilities for identifying individual preexisting structural characteristics that could increase symptom severity and the risk of development. Here, we review the advances in neuroanatomical research on these adaptations in PTSD and discuss how those modifications in prefrontal and anterior cingulate circuitry impact the severity and development of the disorder, detaching the research from an amygdalocentric perspective. In addition, we investigate existing and contradictory evidence regarding the preexisting neurobiological features found mostly in twin studies and voxel-based morphometry (VBM) reports.

Behaviors and Actions of the Strength and Conditioning Coach in Fostering a Positive Coach-Athlete Relationship.

ABSTRACT: Carson, F, Blakey, M, Foulds, SJ, Hinck, K, and Hoffmann, SM. Behaviors and actions of the strength and conditioning coach in fostering a positive coach-athlete relationship. J Strength Cond Res 36(11): 3256-3263, 2022-A number of models have been developed to explain the various factors that affect coach-athlete interactions; however, they have had limited application to strength and conditioning (S&C). A systematic review of the literature was completed using the databases SPORTDiscus Full Text, MEDLINE, Global Health, Academic Search Complete, and PsychINFO, sourcing articles related to S&C coach-athlete relationships. An initial search yielded 1,364 articles, which when screened against the inclusion criteria was narrowed to 8 articles relating specifically to the S&C coach-athlete relationship. Four major themes were identified throughout the included articles: leadership styles; perceptions of leadership; coach knowledge, experience, and training; and building relationships. These themes highlighted that positive coach-athlete interactions are fostered through a mutual understanding of the S&C coach's responsibility to improve performance and reduce injury through scientific methods, with an awareness of different psychosocial behaviors of both the coach and the athlete. This will create a mutual interconnectedness whereby both parties can participate in a functional dyad. Three practical applications deduced from the findings identified the importance of building an autonomy-supportive environment, keeping knowledge and expertise at a high standard, and embracing the whole person rather than just the athlete. These teachings aim to guide S&C coaches through the necessary actions and behaviors recommended to successfully build and foster positive S&C coach-athlete relationships.

Motivation and Behaviour Change in Parkrun Participants in the Western Cape Province, South Africa.

Mass participation events are promoted in South Africa as a positive public health initiative. Parkrun has grown to be one of the most popular. The present study identifies the motives of residents in the Western Cape Province to join parkrun and how their involvement influences future physical activity levels. Participants (N = 1787) completed a survey consisting of demographic history, parkrun participation history, motivations for participation, and physical activity-related behaviour changes associated with parkrun participation. The majority of participants were female (n = 952) and over 50 years of age (median = 50; IQR = 38-59). Along with health-related benefits, the provision of a safe and organised event was reported as a key motive to participate. The social connectedness developed by parkrun encouraged continued participation and promoted uptake of more physical activity. Close to half the participants reported increases in physical activity levels after joining parkrun, which demonstrates the benefit obtained from participation in structured mass participation events. With the large diversity in socioeconomic status in South Africa related to physical activity levels, parkrun provides a protected and engaging environment that provides opportunity for increased physical activity and potentially reducing the burden on the healthcare system.

The Impact of the COVID-19 Lockdown on European Students' Negative Emotional Symptoms: A Systematic Review and Meta-Analysis.

Considerable changes to higher education approaches, as a response to the global coronavirus pandemic, has increased the stress on university students. The impact of these changes has had an effect on the negative emotional symptoms being experienced, which can lead to more severe mental health issues. The purpose of this meta-analysis was to determine the prevalence of anxiety, depression and stress during the coronavirus lockdown. A systematic review of three electronic databases (Google Scholar, PubMed and Medline) was conducted, with 13 studies from different European countries reporting data on students and their negative emotional symptoms identified. The random-effects model was used to perform the meta-analysis on anxiety, depression and stress. The overall pooled prevalence rate was 55% (95% CI: 45-64%) for anxiety, 63% (95% CI: 52-73%) for depression and 62% (95% CI: 43-79%) for stress. The impact of the coronavirus pandemic on negative emotional symptoms has been serious with studies reporting high prevalence rates for these. Isolation, reduced social contact, duration of quarantine and restrictions, which are the characteristics of a lockdown, played an important role in increased negative emotional symptoms for students. Countries have to be aware of this situation and develop mental support strategies to mitigate the impact.

Examining Negative Emotional Symptoms and Psychological Wellbeing of Australian Sport Officials.

Sports officials are exposed to numerous performance and personal stressors, however little is known about their mental health and psychological wellbeing. This study investigated levels of mental health and psychological wellbeing of sports officials in Australia, and the demographic, officiating, and workplace factors associated with these outcomes. An online survey consisting of demographic and officiating questions, and measures of work engagement, mental health and psychological wellbeing was completed by 317 officials. A negative emotional symptoms score was computed. Associations between key demographic, officiating, and workplace factors with negative emotional symptoms and psychological wellbeing were assessed using univariate and multivariate analyses. Officials who were younger, not in a committed relationship, having lower levels of education, and less officiating experience reported higher levels of negative emotional symptoms, while males, older than 50 years, in a committed relationship and more officiating experience had higher levels of psychological wellbeing. The ability to self-manage workload and demonstrate professional autonomy were strongly associated with negative emotional symptoms and psychological wellbeing. Officials reported high negative emotional symptoms, but also high levels of psychological wellbeing. The ability to manage workload and to express professional autonomy are important determinants of mental health and wellbeing levels of sports officials.

The Coach-Athlete Relationship in Strength and Conditioning: High Performance Athletes' Perceptions.

The primary purpose of this study was to investigate high performance athlete perceptions of strength and conditioning coaches, specifically, (1) their character traits, (2) the effective behaviours that display these traits, and (3) how these relationships were fostered. Using the 3+1 C's model of coach-athlete relationships as a framework (Jowett, 2007), 12 semi-structured interviews were conducted with high performance athletes (six female; six male) representing a variety of sports (i.e., freestyle wrestling, triathlon, field hockey, cycling, rowing, rugby union, netball, table tennis, and ice hockey). Participants ranged in age from 18 to 53 years (M = 29, SD = 9). Interviews took between 19-47 min and were transcribed verbatim. The transcripts equated to a total of 188 pages of data that were analyzed, coded, and further grouped into higher-order themes and general dimensions. The findings revealed 14 higher-order themes categorized under the 3+1 C's general dimensions of closeness, commitment, complementarity, and co-orientation.

Examining the Mental Well-Being of Australian Sport Coaches.

Background: Research has highlighted the multitude of factors that are negatively associated with coach mental well-being but has failed to investigate how the determinants of mental well-being can affect the coach both positively and negatively. Accordingly, the aim of this study was to investigate levels of mental well-being among sport coaches and assess whether areas of work life-specifically workload and control-are related to levels of mental well-being. Method: An online survey comprising demographic and coaching experience details, the Areas of Work Life Scale (AWS), and the Warwick-Edinburgh Mental Well-Being Scale was completed by 464 Australian coaches involved in a range of sports. Differences in coach mental well-being according to key demographic and coaching-related subgroups were assessed using separate t-test and ANOVA analyses and the magnitude of effects was determined using Cohen's d and the eta-squared (ή2) statistics. Multiple linear regression was used to examine relationships between both workload and control and mental well-being after controlling for age, gender, coaching setting and weekly coaching activity. Results: The findings indicate poorer mental well-being among both male and younger coaches and indicate that coach mental well-being is related to the ability to self-manage the workload associated with their role as a coach as well as greater autonomy over coaching-related tasks and activities. Specifically, a one-unit increase in AWS workload and AWS control were associated with ~three- and ~four-unit increases in coach mental well-being, respectively. Conclusion: Greater provision of resources and education is required to assist coaches to manage their own mental well-being, while being supported by the organisation they coach for. Enabling coaches to balance their coaching requirements and to have control over their environment will improve their ability to constantly coach at a high standard.

Every Day's a New Day: A Captain's Reflection on a Losing Season.

Being captain of any team is a significant and prestigious position. In elite sport, the captain plays a vital role in both team and organisational leadership. To date there has been minimal research investigating captaincy, and none assessing the impact of regularly losing performances. A captain of a women's national basketball league team participated in an in-depth, semi-structured interview reflecting on her experience during a losing season. Following Schutz's (1967) framework, a social phenomenological analysis approach was taken, with seven higher-order themes emerging: being captain; relationship with coaching staff; relationship with teammates; team development; stressors; stress management; and self. Results suggest that while poor results affect all team members, there are increased levels of stress for the captain. The captain is expected to lead by example and avoid external expression of negativity. Further strains are placed on the captain, as they are the conduit between coaching and playing groups. As a result, the captain needs to have good support networks, from a variety of sources, to cope and minimise the impact on personal performance.

Self-determined motivation in rehabilitating professional rugby union players.

BACKGROUND: The aim of the present study was to explore the views of professional rugby union players during the early rehabilitation, late rehabilitation and return to play stages, following anterior cruciate ligament (ACL) injury. METHODS: A qualitative dominant, mixed methodological approach was utilized with five players who had suffered an ACL injury requiring reconstructive surgery. A longitudinal approach, concurrent with each player's rehabilitation, consisting of twice monthly interviews, a self-report diary and three established questionnaires (MOS-Social Support Survey, Sherbourne & Stewart, 1991; Sport Climate Questionnaire, Deci & Ryan, n.d.; Injury Rehabilitation Questionnaire, Deci & Ryan, n.d.) were completed. RESULTS: Theoretical thematic analysis was conducted on three distinct phases (Early Limited Participation phase, 10 higher order themes; Late Limited Rehabilitation phase, 11 higher order themes; and Return to Play phase, 9 higher order themes) and coded relating to autonomy, competence and relatedness. CONCLUSIONS: The findings suggest that increased autonomy and control assist emotional and behavioral responses during rehabilitation and return to play, while development of competence increases self-confidence.

Dispositional coping, coping effectiveness, and cognitive social maturity among adolescent athletes.

It is accepted among scholars that coping changes as people mature during adolescence, but little is known about the relationship between maturity and coping. The purpose of this paper was to assess a model, which included dispositional coping, coping effectiveness, and cognitive social maturity. We predicted that cognitive social maturity would have a direct effect on coping effectiveness, and also an indirect impact via dispositional coping. Two hundred forty-five adolescent athletes completed measures of dispositional coping, coping effectiveness, and cognitive social maturity, which has three dimensions: conscientiousness, peer influence on behavior, and rule following. Using structural equation modeling, we found support for our model, suggesting that coping is related to cognitive social maturity. This information can be used to influence the content of coping interventions for adolescents of different maturational levels.

Experiences of professional rugby union players returning to competition following anterior cruciate ligament reconstruction.

OBJECTIVES: The purpose of this study was to gain a greater understanding of the emotions and coping strategies utilized when returning to competition following anterior cruciate ligament (ACL) reconstruction. DESIGN: A qualitative approach, consisting of five semi-structured interviews and a pre-designed diary, was conducted concurrent with each 'player's return to competition, allowing each to record emotional responses experienced and identify coping strategies employed. PARTICIPANTS: Five professional male rugby union players, who had suffered an ACL injury that required surgical reconstruction, participated in the study. Each had spent between six to twelve months in rehabilitation. RESULTS: Content analysis was conducted on both pre- and post- return data, identifying 12 higher order themes. Confidence building; anticipation; anxiety; physical preparation; psychological preparation; and social support were prevalent pre-return to competition. Post-return higher order themes consisted of confidence building; positive performance emotions; performance anxieties; problem focused coping; social support; and dealing with fears. CONCLUSIONS: For the players in this study, gaining confidence in the injured knee joint appears to be influential, with increases in confidence provided by completing clinical and sport specific tests, and by performance accomplishments. Successful return can be enhanced further by the use of a specific goal setting program aimed at reintroducing the player to competition.
