The transition of elite youth footballers through academy systems towards the first team is highly complex, competitive, and often unsuccessful. A myriad of factors including technical competence, physical prowess, and the development environment combine to determine youth player progression. Current research has focused on broad investigations of multiple clubs and stakeholders, providing a valuable overview of the key aspects associated with elite youth player transition. This study aimed to provide an in-depth, context-specific investigation of key stakeholders within an elite level club in the United Kingdom (UK). Seven key stakeholders including the head of the academy ( n = 1), the head of sports science ( n = 1), coaches ( n = 3), and lead sports scientists ( n = 2) were recruited. Framework analysis led to the development of a practical framework outlining the key facilitators and barriers of youth-to-first-team transition. Facilitators of transition included overcoming adversity, high-level physical prowess, exceptional technical competence, and possessing at least one elite-level attribute. Barriers to transition included a lack of opportunity, lucrative youth player contracts and a lack of development-specific coaching. In addition, the developmental environment and developing individuals within a team environment were key influences on youth-to-first-team transition. This study complements recent broad investigations of the UK and global stakeholders by corroborating many of their findings while providing transferable, context-specific accounts of applied issues related to successful transition to first-team football.

Decision-making is critical to team invasion game performance. As such, understanding how to measure and develop it is important to researchers and practitioners. However, due to the abundance of assessments available in this area, the optimal use of these assessments is still unclear. The current systematic scoping review summarises and examines the quality of reporting of the available literature on decision-making assessments that can be used in the context of youth team invasion games. It uses an ecological dynamics perspective to evaluate the extent to which the included decision-making tasks adhered to principles of representative task design, specificity of perception and action components and constraints present in each task. The results revealed that soccer was the most frequently studied invasion game (70% of studies). While realistic task (85% of studies) and individual constraints (68% of studies) were often present in decision-making tasks, environmental constraints received far less attention (9% of studies). About one-third of studies were situated on either end of the controlled laboratory in situ study continuum (controlled laboratory = 35%, in situ = 33%). In total, 39% of studies coupled sport-specific perception and action components. Furthermore, studies that implemented sport-specific perception–action coupling featured much smaller sample sizes than those without. The findings of this systematic review can aid researchers and practitioners who want to measure decision-making skill in youth team invasion game athletes by allowing them to make informed choices about which assessment to use based on the extent to which an assessment matches a set of pre-determined criteria.

Engaging with learning and development opportunities is the hall mark of a committed lifelong learner. In this study, we aimed to highlight the benefits of the learning and development achieved by participating coaches on the Olympic Solidarity (OS) Tennis programme. This coach development programme is a joint venture between OS, the International Tennis Federation, and its member nations to deliver certification courses for the coaches of advanced as well as high-performance players. This study is presented in two progressive parts: a web-based survey (Part 1) and semi-structured interviews (Part 2). In Part 2, we interviewed 12 participants from 12 different countries and four coach developers/tutors involved in programme delivery. The coaches in Part 1 were characterised by long-term engagement with tennis coaching and enhancing their own learning and development. Statistical analyses showed no significant difference between any of the variables examined. The interview analyses revealed three main themes: direction and strength of effort; perceived status and prestige of completion; and positivity and purpose. We conclude by discussing short-, medium-, and long-term advantages coaches identified from the programme.

Through interactions with important social agents (coaches, parents, and peers), youth athletes will infer that being successful in sport falls somewhere along the continuum between (a) improvement and hard work and (b) winning at all costs. The environment created as a result of these interactions has important implications for athlete mental health and future sport participation. This study examined the relationships between peer-initiated motivational climate, athlete wellbeing, and intention to return to the team. Youth athletes ( N = 130; Mage = 13.45 years) from nine competitive ice hockey teams completed a questionnaire near the end of season. Using mixed-effects linear modeling, findings revealed that a task-related peer climate significantly predicted wellbeing ( β = 0.32, 95% CI [0.18, 0.47]) and intention to return ( β = 0.43, 95% CI [0.17, 0.68]), whereas an ego-related peer climate was not significantly related to wellbeing ( β = 0.10, 95% CI [−0.07, 0.26]) or intentions to return ( β = −0.29, 95% CI [−0.58, 0.01]).

Player development programmes in sports are considered crucial pillars for the development of young players and countries’ international sporting success. As resources are limited, coaches preferably decide which players to select for these programmes at a young age. This is particularly true for early-starting sports such as table tennis. However, the selection criteria used by coaches and the decision-making processes in player selection contexts are widely unknown. To address this gap, we conducted 15 in-depth semi-structured interviews with table tennis coaches with high expertise in the identification and development of talented young players. Here we show that the concept of ‘talent’ and the process of player selection in table tennis are highly complex phenomena with three main areas of interest identified: (a) general aspects regarding ‘talent’ (in table tennis), (b) specific selection criteria including individual as well as environmental aspects, and (c) the process of player selection. One main finding is that coaches see ‘talent’ as dependent on various factors including (relative) age, maturation as well as practice and previous experience. Furthermore, coaches appear to include both individual (e.g., technical skills) and environmental criteria (e.g., parents’ support) in their decision-making process. Finally, the interviews revealed that player selection decisions are usually made by multiple coaches during group meetings, suggesting the relevance of group processes and dynamics. In summary, this study provides new findings regarding the understanding and discovery of ‘talent’ in table tennis that can help practitioners and open new avenues for further research on player selection in sports.

Although neuromuscular injury prevention programs decrease injuries, implementation is challenging. Netball Australia developed the Netball KNEE program – a netball-specific warm-up program designed for netball coaches, players and support staff to enhance movement efficiency and prevent injury. It contains exercises for warm-up/footwork, strength, balance/landing and agility. This study aimed to explore the Reach, perceived Effectiveness, Adoption, Implementation and intended Maintenance of the Netball KNEE program in community netball. Community netball coaches ( n = 257) from 52 community netball clubs completed an online survey on their familiarity with the KNEE program (Reach), satisfaction and perceived effectiveness (Effectiveness), use of the program in training (Adoption), use of specific program components and provision of feedback (Implementation) and intended future use of the program (Maintenance). 66.5% of coaches who responded to the survey were familiar with the KNEE program (Reach), and 43.0% of coaches reported using the program weekly (Adoption). Most coaches who were familiar with the program were satisfied with it (87.2%) and perceived it to be effective in reducing injuries (77.0%) (perceived Effectiveness). Only 58.7% of the 155 of coaches who adopted the program reported using all activity categories (warm up/footwork, strength, balance/landing and agility) (Implementation). Warm up/footwork activities were reported to be used most commonly (by 99.4% of coaches). Reported provision of feedback on program key principles (e.g., take off, landing, deceleration, changing direction) was variable (54.2%–97.4%) (Implementation). Study findings suggest the need for strategies to improve the reach, adoption and implementation of the KNEE program in community netball.

The wet bulb globe temperature (WBGT) is widely used in athletics for assessing heat stress. Sports governing bodies provide a wide variety of recommendations on how often to take WBGT measurements during activities like practices and competitions. This can leave coaching staff and other sports medicine personnel in a quandary as to what is the “best practice.” Our study is the first to use a large dataset to quantify the variability of WBGT within practice and competition sessions, and to identify the impact of using different measurement rates on the WBGT. The study leverages 6 years of data from thousands of American football practice and competition sessions from across Georgia, USA. We observed that, on average, WBGTs are coolest in the morning (26.67°C) and evening (24.84°C), and hottest in the midday (30.23°C) and afternoon (27.21°C). The variability within sessions tended to be greater for morning, midday, and afternoon than evenings, with session standard deviations of 0.96°C to 1.27°C and ranges of 2.67°C to 3.55°C when controlling for duration. WBGTs also tended to increase over time in morning sessions and decrease over time during afternoon and evening sessions. These changes are clinically important. We found that Georgia High School Association (GHSA) WBGT activity modification categories often changed during sessions, especially in the morning, midday, and afternoon where a change in GHSA category of ≥1 occurred in 57% to 76% of sessions. Considering this variability, our results indicate that more frequent measurements better capture maximum WBGT values over a session and reduce the likelihood of misclassifying activity modification.

This study systematically reviewed and quantified the scientific literature on the effects of integrative neuromuscular training (INT) on change of direction (COD) performance among court-based sports players. A comprehensive keyword search was conducted on December 15, 2022, across six electronic bibliographic databases: SPORTDiscus, PubMed, Web of Science, Academic Search Ultra, Scopus, and Google Scholar. Following the application of eligibility criteria, a total of 23 studies with 901 participants were included in this review. Meta-analysis was employed to estimate the pooled effect size of INT interventions on COD performance. The findings demonstrated that INT interventions resulted in a significant reduction in COD task completion time for court-based sports players, compared to control groups (standard deviation [SD] = 0.38, 95% CI = 0.27, 0.49; I^2 = 98.76%). However, it was observed that the efficacy of INT on COD performance was influenced by factors such as gender, sport type, and specific metrics of COD task measures. Consequently, it is imperative to consider these potential variations when interpreting the results and planning future research. In conclusion, INT exhibited superior effectiveness in improving COD performance compared to control groups among court-based sports players. We recommend that strength and conditioning professionals incorporate INT into their comprehensive conditioning programs. However, it is important to acknowledge the potential variations in outcomes attributable to participant-specific characteristics, including gender, sport type, and the nature of COD tasks. This understanding will facilitate the optimal application of INT, thereby enhancing athletic performance across diverse sporting contexts.
本研究系统地回顾和量化了有关综合神经肌肉训练(INT)对球场运动运动员方向改变(COD)表现影响的科学文献。2022年12月15日，对六个电子书目数据库进行了全面的关键词搜索:SPORTDiscus、PubMed、Web of Science、Academic search Ultra、Scopus和Google Scholar。根据入选标准，本综述共纳入23项研究，901名受试者。采用meta分析估计INT干预对COD表现的综合效应大小。研究结果表明，与对照组相比，INT干预导致球场运动运动员COD任务完成时间显著减少(标准差[SD] = 0.38, 95% CI = 0.27, 0.49;i ^2 = 98.76%)。然而，我们观察到INT对COD表现的影响受到性别、运动类型和COD任务测量的特定指标等因素的影响。因此，在解释结果和规划未来研究时，必须考虑这些潜在的变化。综上所述，在以球场为基础的运动员中，与对照组相比，INT在提高COD表现方面表现出更好的效果。我们建议力量和调节专业人员将INT纳入他们的综合调理计划。然而，重要的是要认识到可归因于参与者特定特征的潜在结果变化，包括性别、运动类型和COD任务的性质。这种理解将促进INT的最佳应用，从而提高在不同运动环境下的运动表现。

In conclusion, INT exhibited superior effectiveness in improving COD performance compared to control groups among court-based sports players. We recommend that strength and conditioning professionals incorporate INT into their comprehensive conditioning programs. However, it is important to acknowledge the potential variations in outcomes attributable to participant-specific characteristics, including gender, sport type, and the nature of COD tasks. This understanding will facilitate the optimal application of INT, thereby enhancing athletic performance across diverse sporting contexts.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"21 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131858756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports the multi-year periodised international competition engagement of elite top 100 [T100] and 250 [T250] female tennis players during their youth. Tournament data was analysed for 258 female players from 13 to 18 years of age. Players were categorised into groups based on peak professional ranking of T100 or T250. ‘Fast’ or ‘slow’ achieving T100 players were further classified according to the years taken to achieve a professional T100 status. International tournament and match volumes were quantified for junior and professional categories, along with measures of competition density (i.e., time between tournaments and consecutive tournaments). Tournament quality and category were determined by ranking point offerings. A two-way analysis of variance determined the effects of age and ranking group on tournament play. Significant interaction effects for age and ranking group were observed for all junior and professional category tournaments ( p < .05). Significantly higher annual junior tournament volumes featured in the schedules of T100 at ages 14 and 15 ( p < .05) while participation in annual professional tournaments increased for all players at ages 17 and 18 ( p < .05). The top 100 players played more annual matches than the T250 group at 14–16 years ( p < .05). Significant main effects for age revealed decreased days between tournaments and increased consecutive tournaments at 15 years ( p < .05). Increased volume and density of tournament-play exist from 14 years professional female tennis players. Faster achieving T100 players contest higher-quality junior and professional tournaments at earlier ages. These distinctive tournament characteristics can underpin training and competition scheduling recommendations used by national tennis federations.

Players who lack the knowledge to recognise the signs and symptoms of concussions may be less likely to disclose their injury. New Zealand Rugby's Community Concussion Initiative includes an interactive education session highlighting peer-recognition of concussions. This mixed-method study examined the effect of an education session on high school players’ concussion knowledge and attitudes as well as the impact of player demographics on these variables. Focus groups were used to explore player experiences. The RoCKAS-ST was used to measure concussion knowledge/attitudes before and after the education session. Multiple linear regression examined associations between demographic variables, including school decile (relative wealth of the geographic region the school serves), and pre-education concussion knowledge/attitudes scores. Wilcoxon signed-rank tests compared pre-concussion and post-concussion knowledge/attitudes scores. Qualitative data were analysed via thematic analysis. Overall, 532 players completed questionnaires; 75 players participated in focus groups. Pasifika players had lower concussion knowledge than NZ Europeans ( p < .001). Mid-decile schools had higher concussion attitudes scores than low decile schools ( p < .001). Pre-education and post-education session concussion attitudes and knowledge scores did not differ significantly, suggesting the one-off education session was not successful in improving these outcomes. Players identified: (i) the education session to be valuable, but some uncertainties remained; (ii) the importance of player comfort, interaction and comprehension; (iii) the need for role models, real stories and regular content refreshers. Requests for presenter diversity, support and easily understood information were more prominent in Māori/Pasifika and low-decile groups. Greater consideration of these factors is necessary in the development of education interventions.
