Examining the theory of challenge and threat states in athletes: do predictions extend to academic performance?
Challenge and threat responses have been seen to predict success in meaningful performance environments, however, it is not as clear whether challenge and threat states predict academic outcomes. We tested if predictions from the Theory of Challenge and Threat in Athletes (TCTSA) can be extended to an academic context, by considering antecedents and outcomes of challenge and threat states as well as whether cardiovascular markers predicted academic performance. Thirty-six undergraduate students were asked to give speeches on an academic topic, and their cardiovascular responses, overall annual marks, and marks in a specific presentation assessment were recorded. Challenge and threat indexes failed to predict either of the performance measures. Limited support was found for other hypothesised relationships of the TCTSA, with challenge states predicting greater reinvestment, which was opposite to that hypothesised. Results suggest that predictions of the TCTSA may not be as pertinent in understanding goal pursuit in academic settings
Examining the Predictors of Mental Ill Health in Esport Competitors
Few research studies have examined the predictors of mental ill health in esports. This
study addresses that gap by investigating stressors, sleep, burnout, social phobia anxiety and mental
ill health in esport athletes. An online survey was disseminated to competitive student esport athletes
(n = 313) residing in the UK. The survey included measures of stressors resulting from competing in
esports, sleep quality, burnout, and social phobia, as well as outcome measures of mental ill health.
Hierarchical regression analyses examined these relationships. All the hypotheses were supported,
with stressors significantly predicting sleep quality, burnout, and social phobia anxiety, and stressors,
sleep quality, burnout, and social phobia anxiety were all significant positive predictors of mental ill
health. The strength of these predictions varied, for example, the daytime dysfunction subscale of
sleep was a strong predictor of all outcome variables; two subscales of burnout, reduced sense of
accomplishment and exhaustion significantly predicted each of the three mental ill health outcome
variables, and two subscales of social phobia anxiety, fear and avoidance, significantly predicted
mental ill health. Our study has important implications for player health in esports, highlighting
interventions that could target specific aspects of stress, sleep, burnout, and social phobia anxiety to
improve the mental health of those who compete in esports
Indexing Esport Performance
The assessment of an athlete’s performance can play a key role in determining their current state, their readiness to compete, the impact of an experimental manipulation, and/or the influence of an intervention. At present, there is limited empirical evidence stating the indicators that encapsulate individual performance within any esport. To identify the variables that are historically associated with indicating Counter-Strike: Global Offensive performance, a literature review was conducted. Identified variables were accumulated and presented to three technical expert panels composed of world-class esport athletes, researchers, and practitioners. We utilized a modified Delphi method to provide direction concerning the examination of performance in esports. The expert panelists presented numerous opinions on what encapsulates performance, considerations for best practices, and concerns associated with the semantics of performance. This study presents the opinions of various domain-specific experts and encourages the use of more explicit terminology when discussing performance measurement. It was the intention of the project to generate an open discussion rather than draw a unified conclusion on best practices
The effects of simulated vision impairment on performance in football
Footballers with vision impairment (VI) are eligible to compete in the Para sport if they meet a minimum impairment criteria (MIC) based on measures of their visual acuity (VA) and/or visual field. Despite the requirements of the International Paralympic Committee Athlete Classification Code that each sport uses an evidence-based classification system, VI football continues to use a medical-based system that lacks evidence to demonstrate the relationship between impairment and performance in the sport. The aim of this study was to systematically simulate vision loss to establish the minimum level of impairment that would affect performance in futsal. Nineteen skilled sighted players completed tests of individual technical skill and anticipation performance under six levels of simulated blur that decreased both VA and contrast sensitivity (CS). VA needed to be reduced to a level of acuity that represents worse vision than that currently used for inclusion in VI football before meaningful decreases in performance were observed. CS did not have a clear effect on football performance. These findings produce the first evidence for the minimum impairment criteria in VI football and suggest a more severe degree of impairment may be required for the MIC
The influence of student gender on the assessment of undergraduate student work
The aim of this study was to investigate the influence of perceived student gender on the feedback given to undergraduate student work. Participants (n = 12) were lecturers in higher education and were required to mark two\ud
undergraduate student essays. The first student essay that all participants marked was the control essay. Participants were informed that the control essay was written by Samuel Jones (a male student). Participants then marked the target essay. Although participants marked the same essay, half of the participants (n = 6) were informed that the student essay was written by Natasha Brown (a female student), while the remaining participants were informed that it was written by James Smith (a male student). In-text and end-of-text feedback were qualitatively analysed on six dimensions: academic style of writing; criticality; structure, fluency and cohesion; sources used; understanding/knowledge of the subject; and other. Analysis of feedback for both the control and target essay revealed no discernible differences in the number of comments (strengths of the essay, areas for improvement) made and the content and presentation of these comments between the two groups. Pedagogical implications pertaining to the potential impact of anonymous marking on feedback processes are discussed
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

THE DEVELOPMENT OF AN INSTRUMENT TO MEASURE MENTAL TOUGHNESS IN SPORT
The Mental Toughness Questionnaire-48 (MTQ48; Earle, 2006) is the most utilised instrument to measure Mental Toughness (MT) in sport (Gucciardi, Hanton, & Mallett, 2012). To date, preliminary research examining the factorial validity of the MTQ48 has yielded equivocal findings (Gucciardi et al; Horsburgh, Schermer, Veselka, & Vernon, 2009) regarding its ability to measure the 4/6C’s model of MT (Clough, Earle, & Sewell, 2002; Earle). The primary aim of this thesis was to provide a truly comprehensive examination of the factorial validity of the MTQ48 in an effort to provide an adequate measure of the 4/6C’s model of MT. Study 1 re-examined the factor structure of the MTQ48 by using a very large sample of competitive student athletes and found little support for its factorial validity. Inspection of item content revealed concerns regarding the adequacy of MTQ48 items to represent the 4/6C’s model of MT. Study 2 developed the University of Chichester Mental Toughness Questionnaire (UCMTQ) whereby items were generated to better represent the 4/6C’s model of MT. Although the UCMTQ’s factorial validity was superior to the tested models of the MTQ48, the results of Study 2 provided little support for its factorial validity. It was concluded that the poor factorial validity of the UCMTQ could have been due to the inadequacy of the factor definitions developed by Clough, Marchant, and Earle (2007) to represent the core traits underpinning the 4/6C’s model of MT (challenge, commitment, control, and confidence)
Investigating the Comparative Suitability of Traditional and Task-specific Think Aloud Training
The Think Aloud (TA) protocol is used to capture conscious cognition for wide ranging applications. However, the methods used to train the TA technique have been inconsistent involving a mixture of both traditional guidelines (Ericsson & Simon, 1993) and task-specific examples. This study aimed to examine how best to train the TA process. We recruited 20 competitive golfers as research participants, and we randomly assigned them to equal sized groups of traditional TA training as described by Ericsson and Simon (1993) and task-specific training in which participants were familiarized with TA via task-specific examples. Following training, all participants performed a golf task and were asked to TA. We transcribed audiotapes of their verbatim TA content and analyzed them using a deductive framework. We also collected various social validation self-report measures to assess participant perceptions of TA training. Overall, we found no significant differences in the frequency or type of TA verbalizations when comparing traditional and task-specific TA training groups. However, participants in the task-specific training group reported more favourable perceptions of training and found training significantly clearer than did participants in the traditional training group. We suggest that these findings support traditional TA training following Ericsson and Simon’s (1993) training guidelines, but adding task-specific examples seems to increase the familiarity of TA use and facilitate more reliable and accurate cognition data for research use
Perceptions of Effective Training Practices in League of Legends: A Qualitative Exploration
While scientific interest in electronic sports (esports) is steadily growing, there remains an absence of research evidence concerning training practices in specific esports such as League of Legends. Anecdotal evidence suggests that current approaches to training may be suboptimal in terms of performance and, concerningly, linked to negative consequences for player health and well-being. In order to address the lack of literature and aid understanding of the (in)effectiveness of current training practices in esports, our study sought to qualitatively examine the experiences and perceptions of training in a sample of professional and semiprofessional League of Legends players. Through interviews with 10 players who ranked in the top 0.24% of the playing population, three core themes were identified: (a) the state of training, (b) training experiences, and (c) motivational change. This study provides important insights into current training practices in esports and players’ perceptions of the (in)effectiveness of these practices. The paper concludes with practical recommendations for coaches and support staff working in esports
