Coach behaviour has long been known to influence the sporting experience of grassroots players; however, it is currently unclear how the instruments used to assess their behaviour are related. Therefore, the aim of this study is to evaluate the relationships between three observational coaching behaviour tools. Sixteen matches with teams led by four female football coaches were recorded and analysed using three observational instruments: (a) Coaching Behaviour Assessment System (CBAS); (b) Multidimensional Motivational Climate Observation System (MMCOS) and (c) Coach Leadership Assessment System (CLAS). The dimensions measured by each instrument are theorised as being adaptive or maladaptive. The specific objectives of this study are targeted to assess: (a) the commonalities between the three instruments and (b) what differentiated aspects each instrument provides. The results show that both the adaptive and the maladaptive dimensions of the three instruments are positively related among themselves but negatively related to the others. The results also show that the MMCOS is sensitive to behavioural changes during the matches, while the CBAS and the CLAS do not reflect these changes but assess the stability of the behaviour. In conclusion, this research provides empirical evidence supporting the conceptual relationship between the three instruments and of the specific information that each instrument offers. Furthermore, it highlights the need to observe the sport environment more closely in a more diversified way.

This article reports on a survey of concussion knowledge (CK), attitudes (CA) and reporting intention (CRI) amongst a multisport cohort of UK university student-athletes. A cross-sectional study design was used, with 217 student-athletes completing the Rosenbaum Concussion Knowledge and Attitudes Survey – Student Version. The findings show that CK is broadly aligned with previous study cohorts including research in North America, and that sport type had no effect on CK, CA and CRI. Whilst gender did not affect CA or CRI, males returned higher CK scores than females. The respondents’ concussion history did not affect CA. Paradoxically, respondents with a history of concussion had significantly greater CK scores yet were more likely to report an intention to continue playing with SRC symptoms. There are three key implications of these findings. The comparison of findings between males and females highlights the need for a more nuanced conceptualisation of safety and risk in relation to SRC. Second, the evidence suggests a strong need for UK universities to introduce bespoke education programmes and policies formalising the healthcare support and return to learn of students post-SRC. Third, awareness of the complex interplay between SRC knowledge, experience and behaviour will enable coaches across all sports to exercise caution when managing SRC amongst students. The article concludes by arguing that there is a need for further qualitative research to understand how concussion is experienced by UK university students and provided for and accommodated within UK universities.

To explore the differences in training and match load in English Premier League (EPL) 1st team and U23 players. Identifying differences in relative and absolute physical outputs in relation to Maximal Aerobic Speed (MAS) and Maximal Sprint Speed (MSS) and how this informs monitoring and training prescription. Two groups of full-time professional football players (1st team, n = 24 and U23 squad, n = 27) participated in this study. Training and match data were categorised into weekly blocks from Monday to Sunday. Each player's weekly total was then averaged to provide a squad average for each metric examined. Match analysis identified significantly higher distance covered above 120% MAS and distance between 120% MAS and 85% MSS ( p = .04, effect size [ES] = 0.64; p < .01, ES = 1.13) for the 1st team. Distance above 85% MSS was significantly higher for the U23's ( p < .01, ES = 2.92). Training and match data during one-match weeks displayed significantly higher differences in all high-speed variables for 1st team players compared to U23 players ( p ≤ .05, ES = 0.82–1.78). Analysis of training and match data during a two-match week displayed no significant differences for all physical variables ( p > .05). Practitioners should consider the utilisation of individual relative thresholds to identify differences between physical performance variables during training and matches for 1st team and U23 players. Utilising these comparisons to inform training design, could maximise players physical development and potential for successful transition. Importantly, these findings relate to only one EPL club and therefore practitioners should assess their own players’ relative training and game outputs.

It is well-recognised that fulfilling the role of a coach is multi-faceted. In rugby, some of these coaching facets have been studied, however the research has not been reviewed. Reviewing the literature on rugby coaches will inform and guide policies, coach education, research and practice. Therefore, the purpose of this study is to provide a scoping review of the current coach focused literature on rugby union, rugby league and rugby sevens. A scoping review was conducted on five electronic databases (EBSCOhost, PubMed, Scopus, SPORTDiscus, Web of Science) until January 2022 using the PRISMA-ScR guidelines. Participants had to be coaches within rugby union, sevens and league to be included. Data were extracted and analyzed to form a numerical and thematic summary. 105 articles were included. 76% of the studies were on rugby union, 14% on league, 1% on sevens and the remainder focused on a combination of rugby cohorts or did not specify. Three themes were identified via a thematic analysis based on the content of the articles, these were coach knowledge (68%), coach pedagogies (29%), and coach development (4%). The main finding in this review is that research on rugby coaches understood the risk, prevention, and management of injuries. Educational resources should include all aspects of rugby play or training injuries. The importance of the athlete-coach relationship and coach reflective practices was another significant finding. Coaches are encouraged to have a broad understanding of various aspects related to the player's welfare, which can be developed using formal and/or nonformal learning.
众所周知，教练的角色是多方面的。在橄榄球比赛中，这些教练方面的一些方面已经被研究过了，但是这些研究还没有被回顾。回顾橄榄球教练的文献将为政策、教练教育、研究和实践提供信息和指导。因此，本研究的目的是对目前关于橄榄球联盟、橄榄球联盟和七人制橄榄球的教练关注文献进行范围审查。使用PRISMA-ScR指南对5个电子数据库(EBSCOhost、PubMed、Scopus、SPORTDiscus、Web of Science)进行了范围审查，直至2022年1月。参与者必须是橄榄球联盟、七人制和联盟的教练。对数据进行提取和分析，形成数字和专题摘要。共纳入105篇文章。76%的研究是关于橄榄球联盟的，14%是关于橄榄球联盟的，1%是关于七人制橄榄球的，其余的研究集中在橄榄球群体的组合上，或者没有具体说明。通过基于文章内容的主题分析，确定了三个主题，即教练知识(68%)、教练教学法(29%)和教练发展(4%)。这篇综述的主要发现是对橄榄球教练的研究了解了受伤的风险、预防和管理。教育资源应包括橄榄球比赛或训练损伤的各个方面。运动员-教练关系和教练反思练习的重要性是另一个重要的发现。鼓励教练对与球员福利相关的各个方面有广泛的了解，这可以通过正式和/或非正式的学习来发展。

As the sport industry witnesses a surge in the type and volume of data-driven decisions, the general question of the process of information development remains: how is data used to develop meaningful information? And does the presence of novel quantitative data sources lend greater objectivity to match analysis? Study 1 examines how 12 football analysts use the same qualitative (video) and quantitative (event and position) data to develop information constituting a typical opponent report for an upcoming match, while Study 2 investigates the agreement between grade evaluations of these opponent reports by numerous professional coaches. Findings of Study 1 through independent-samples t-tests ( t(18) = 3.922, p = 0.001) indicate a clear dominance of qualitative video data over quantitative event and position data in all opponent reports. Despite the presence of quantitative data sources, analysts tend to prefer annotated video data. Possible relations to previous experience and familiarity with data, coach–analyst preferences and biases are discussed. Results from Study 2 show extremely weak intra-class correlations (ICC) ( r = 0.147; p = 0.011) between different grades awarded to the same video, depicting a clear lack of agreement in what coaches consider a good opponent report. Furthermore, coaches most valued the comprehensibility and relevance of the report. No significant associations were found between use of either data type and better grades. The subjectivity of the coaching process highlighting preferences regarding data validity and negotiations of adopting new key performance indicators (KPIs) is discussed, alongside limitations of the sample as well as the level of coach–analysts involved.

It has recently been identified that the assessment of peak periods of activity better considers the stochastic nature of match-play and the influence that contextual factors have on these peak periods. Limited research exists attempting to link the tactical and physical aspects of performance, especially in female players. Therefore, the current study aimed to assess post-goal locomotor patterns and positional differences on peak match demands in elite female soccer players. Using 10 Hz global positioning system units, a total of 133 player match observations were recorded from 14 matches played by an elite Scottish women's professional soccer team. The total distance (TD), high-speed running distance (>18 km/h) (HSRD) and PlayerLoad™ (PL) were assessed for 1, 3 and 5-minute peak periods using a rolling epoch approach. Playing position and post-goal activity were used as modulating factors. Linear mixed models established a main effect for playing position for the HSRD at peak 1-minute ( p<.001), 3-minute ( p < .001) and 5-minute ( p < .001) epochs. There were also main effects for the playing position for TD at peak 1-minute ( p= .001) and PL at peak-3minute ( p = .002). Team-level data showed a main effect for condition (score vs. concede) for 3-minute TD data and main effects for time (pre vs. post) for 1,3 and 5-minute epochs for PL data. The average and peak values were shown to differ across playing positions for all variables. Likewise, potentially indicative of tactical adjustments significant differences were observed at both a team and player level following scoring or conceding a goal.

Using a pre-post-test design, this study evaluated the impact of implementing a standard on the reliability of player management decision-making within a professional rugby union environment. Five practitioners from a High-Performance Unit (HPU) rated 22 instances of Global Positioning System (GPS)–based external training load information of 14 players across the 2021–2022 season. This rating was whether a peak/trough/normal exposure in load had occurred. The ratings were repeated at four time points (separated by 2 weeks) before (Pre1, Pre2) and after (Post1, Post2) implementing a consensus statement as a subjective standard (using a dashboard) developed previously within the same environment to identify peaks/troughs in player external training loads. Inter-rater agreement between individuals at each voting round was assessed using Light's Kappa, while pre-post-standard intra-rater agreement was determined from Cohen's Kappa (both with 95% confidence intervals). Changes to dashboard usability from implementing the standard were assessed by administering the System Usability Scale to 11 HPU staff at the four time points. Pre-standard moderate inter-rater agreement (Pre1: 0.53 (0.36–0.69), Pre2: 0.60 (0.42–0.77)) increased to almost perfect agreement (Post1: 0.74 (0.57–0.89), Post2: 0.90 (0.79–1)) post-standard. The intra-rater agreement of 2/5 participants was almost perfect post-standard, while it remained within substantial levels for the others. A linear mixed model ( χ2(3) = 8.85, p = 0.03) illustrated a slight increase in dashboard usability after incorporating the standard (Pre1: 84.09, Pre2: 81.36; Post1: 87.73, Post2: 87.27). Overall, the results highlighted that the subjective standard enhanced reliability of practitioner agreement for the selected decision.

In Judo, one of the combat sports, athletes must endure high intensity, long-term training sessions that extend for long durations to achieve outstanding performances. Authentic leadership plays an essential role in this combat sport by supporting players who may experience slower growth and in enduring the rigorous and long-term training. Despite this leadership type being essential for fostering development and success in judo, few studies have been conducted on authentic leadership in the context of sports. This study investigated the relationship between judo coaches’ authentic leadership and judo athletes’ self-management and perceived performance; it also investigated the mediating effects of self-management on the relationship between authentic leadership and perceived performance. We used a convenience sampling method to recruit 274 Korean judo athletes. We conducted frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and structural equation modeling. The results showed that judo coaches’ authentic leadership had a significant effect on athletes’ self-management, but no significant effect on their perceived performance. Additionally, judo athletes’ self-management had a significant effect on perceived performance. Further, self-management had a mediating (complete) effect on the relationship between judo coaches’ authentic leadership and athletes’ perceived performance. Our results show that judo coaches’ authentic leadership does not directly affect athletes’ perceived performance, but has an indirect effect through the mediating effect of self-management. In other words, judo coaches’ authentic leadership can directly enhance athletes’ self-management and indirectly enhance athletes’ perceived performance, thereby suggesting that it is an important factor in athletes’ performance progress.

The aim of this study was to characterize performance patterns of attack and defence of football teams, and the inter-team's relation throughout the game. First and second leg of the Brazilian Cup Final 2018 Under-20 category were recorded using two video cameras. Three hundred twelve attacks and defences sequences in the two football matches were analyzed. All players and the ball were tracked throughout the matches, then notational and spatiotemporal variables were measured: attack duration, number of actions per attack, occupied area, team centroid, ratio between number of action and attack duration, total centroid trajectory, and ball displacement. Those variables were grouped using Ward's minimum variance method. The results showed that: (i) teams presented variated styles of play in attack and defence intra and intermatches; (ii) spatial variables such as positions and displacements contributed the most to separate the patterns; (iii) the interteams synchrony found throughout the game revealed different outcomes; and (iv) specific attacking patterns led to shoot to goal. We concluded that football teams vary their style of play within match and intermatches; spatial variables such as positions and displacements contributed the most to separate the patterns; and the interteam relation revealed synchrony throughout the game.

Sport psychology consulting services are commonly used by elite athletes in developed countries, but little is known about the athlete's perceptions of such services in developing countries. The present study examined the accessibility, receptivity, and perceived benefit of sport psychology services (via a sport psychology services questionnaire) through a cross-sectional survey of elite athletes ( N = 32; Mage = 23.06 years, SD = 5.81) from 12 nations of the Oceania region who participated in the Gather, Adjust, Prepare, Sustain programme. These nations were Vanuatu, Fiji, Tuvalu, Tonga, Solomon Islands, Cook Islands, Norfolk Island, Niue, Nauru, Kiribati, Samoa, and Papua New Guinea. The results revealed that only a quarter of the athletes had ongoing access to sport psychology consulting services. Over half reported that they were receptive to sport psychology services and perceived that these types of services would be beneficial. The most desired services related to performance enhancement (e.g. performance under pressure). The athletes reported mixed levels of knowledge regarding mental skills, and most knowledge concerned the use of mental skills in competition. Specifically, most athletes rated their knowledge of mental skills at either the low (e.g. imagery) or high (e.g. goal setting, focus, and self-talk) range, and relatively fewer athletes rated their knowledge in the mid-range. The athletes demonstrated interest in learning more mental skills to enhance their performance. These findings indicate that a need exists for sport psychology service providers among athletes in the Oceania region. Existing non-local providers may also consider supplying services through digital modalities.
