Female soccer players report that the menstrual cycle (MC) can negatively impact sporting performance, with barriers identified in communicating their MC experiences to coaches and support staff. Whilst research is growing, there are few studies exploring the coaching staff perspective in soccer, and none from those at the youth level. The aim was to explore soccer coaches’ awareness, perceptions and experiences of the MC and the perceived impact on performance. Thirteen coaches (female n = 4; male n = 9, aged 33 ± 9 years) from Scottish elite adult and youth soccer participated in individual semi-structured interviews (average interview time 39 ± 11 min). Interviews were audio recorded and transcribed verbatim, with reflexive thematic analysis (RTA) performed. RTA generated three key themes from 232 meaning units: environment and culture, coach–athlete dynamic, and coach support and education. Coaches perceived a societal culture of the MC being hidden, or taboo, with similar barriers noted within the club environment. Coaches were often embarrassed to discuss the MC with players and believed players were embarrassed. Communication differed depending on the coach–athlete relationship, with trust and familiarity cited as improving comfort in communication. Coach awareness and understanding of the MC both generally and within a sporting context influenced their perceived ability to communicate and support players. Findings highlight the need to support coaches by providing MC education, and practical guidance on how to support players’ health and wellbeing. Improved confidence in communication should allow players to feel supported and normalise conversations about the MC.

This article presents the findings of a season-long investigation of video-based coaching (VBC) practices in an English youth soccer academy. During the period of fieldwork, the lead author immersed themselves within the academy setting, in which they observed 22 VBC sessions and also day-to-day interactions between coaching staff relating to these activities. In addition, 18 interviews were conducted with 5 coaching staff, totalling 8 h of in-depth interview data. The fieldnotes and interview transcripts were iteratively analysed, utilising Goffman's dramaturgical writings and Groom et al.'s grounded theory of VBC. Our analysis produced two overarching themes. These were (a) how the coaching staff concealed that VBC sessions were principally designed to develop ‘high priority’ players and (b) how the coaching staff purposefully withheld critical thoughts and feelings about their player's performances, preferring instead to strategically focus on the provision of positive messages during VBC sessions. These findings contribute to the limited investigation of this aspect of coaching and demonstrate the importance of educating coaches to acknowledge how VBC can be influenced by and used to respond to workplace demands and expectations.

The nurturing of young players in youth academies is seen as an important step on the way to becoming a full professional in the sport of soccer. This longitudinal multi-study investigation, spanning 2009 to 2021, analysed the career paths of Spanish academy soccer players. It consisted of three studies investigating players’ transition from academy to professional status and the identification of technical skills and psychological traits which could distinguish future professionals from amateurs. The sample involved 198 male academy soccer players (aged 13.5–17.9) from two Madrid-based professional clubs. Study 1 assessed the outcomes of these players a decade after their academy-level evaluations. Studies 2 and 3 focused on the subgroup of 85 players whose playing status could be verified a decade later. Results showed that 12 players (6.1%) progressed to full-time professional soccer. Of these 12, just 7 reached Spain's highest professional league within 10 years of their final academy tests. Significant differences favouring professional players were observed in the trait of ‘self-confidence’, ‘ball reception’, ‘dribbling forward with the ball’ and coaches’ global technical assessments. In conclusion, the chances of academy soccer players achieving professional status are low. Accordingly, providing more developmental opportunities before deselection is crucial to maximise player potential. Coaches could prioritise players’ self-confidence and ball control to increase the conversion rate of academy players to professional status. Furthermore, recruitment of players who are already strong in these attributes could also improve the productivity of talent development pipelines.

As a variation of small-sided games (SSGs), Thomas Tuchel's hexagonal shaped possession drills attracted a lot of attention in coaches’ soccer education. Changing certain variables (e.g. pitch size) is one traditional approach to provide an optimal stimulus for a specific training goal. Therefore, the presented field study investigated whether hexagonal shaped drills show changes in tactical key performance indicators (KPIs) using positional data in a controlled experimental setting. Data were collected using player tracking systems (1 Hz) in 5 versus 5 SSGs in both the full-size pitch and pitch with cut-off corners condition. At match-related level, trial duration and outcome were examined. At player-related level, the tactical KPIs effective playing space (EPS), length-per-width ratio, space control and overplayed defenders were analyzed. The results show significant differences in length-per-width ratio (attacking team), the EPS and space control (30m-zone). However, it could not be confirmed that hexagonal shaped drills are played more vertically and faster toward the goal than on a normal pitch, as there were no changes in trial duration, outcome or overplayed defenders. Nevertheless, an experimental positional data analysis paradigm is a useful approach to investigate tactical principles in high-level professional soccer.

The study aimed to investigate the impact of game formats on the running and technical–tactical performance of young soccer players, as well as on players’ dynamics of spatial occupation during competitions. Eleven players of a U-11 team (11.10 ± 0.39 years old) participated in three competitions specifically designed to analyze the impact of different game formats: 5vs5 (F-5), 7vs7 (F-7) and 11vs11 (F-11). Players’ running performance and dynamics of spatial occupation were analyzed using the GPSs devices from WIMU PRO™ devices (10 Hz). Players’ and team's technical–tactical performance was also analyzed using the Team Sports Assessment Procedure (TSAP) and the Offensive Sequence Characterization System (SCSO), respectively. It was observed that the teams tended to adopt a less direct style in the F-11 ( LpW: F7 vs. F-11 p = 0.001 and F-5 vs. F-11 p = 0.002), with a lower rate of spatial exploration (F-7 vs. F-11 p = 0.001 and &&F-5 vs. F-11 p = 0.001) and lower running demand ( Sprint: F-7 vs. F-11 p = 0.001 and F-5 vs. F-11 p = 0.014; HSR: F-7 vs. F-11 p = 0.001 and F-5 vs. F-11 p = .001). In addition, the F-11 allowed the players to have less involvement during the match (F-7 vs. F-11 p = 0.003; F-5 vs. F-11 p = 0.001), as well as a lower technical–tactical performance (F-7 vs. F-11 p = .003 and F-5 vs. F-11 p = .005). Our results highlight the importance of adjusting the game formats used in youth competitive environments to players’ intrinsic dynamics.
本研究旨在调查比赛形式对青少年足球运动员的跑步和技术战术表现的影响，以及对球员在比赛中的空间占用动态的影响。一支 U-11 球队的 11 名球员（11.10 ± 0.39 岁）参加了三项比赛，旨在分析不同比赛形式的影响：5vs5（F-5）、7vs7（F-7）和11vs11（F-11）。使用 WIMU PRO™ 设备（10 Hz）的全球定位系统分析了球员的跑步表现和空间占用动态。此外，还分别使用团队运动评估程序（TSAP）和进攻序列特征系统（SCSO）分析了球员和球队的技术战术表现。据观察，在 F-11 中，球队倾向于采用较少的直接风格（LpW：F-7 vs. F-11 p = 0.001，F-5 vs. F-11 p = 0.002），空间探索率较低（F-7 vs. F-11 p = 0.001，&&F-5 vs. F-11 p = 0.001），跑动需求较低（Sprint.F-7 vs. F-11 p = 0.001，&&F-5 vs. F-11 p = 0.002）：F-7 vs. F-11 p = 0.001，F-5 vs. F-11 p = 0.014；HSR：F-7 vs. F-11 p = 0.001，F-5 vs. F-11 p = 0.001）。此外，F-11 使球员在比赛中的参与度降低（F-7 vs. F-11 p = 0.003；F-5 vs. F-11 p = 0.001），技术战术表现也较差（F-7 vs. F-11 p = 0.003，F-5 vs. F-11 p = 0.005）。我们的研究结果凸显了在青少年竞技环境中根据球员的内在动力调整比赛形式的重要性。

To map and summarise the sports coaches’ and support staff's perspectives on athlete monitoring to explore the breadth of literature, identify knowledge gaps and inform future research. Scoping review based on the Joanna Briggs Institute (JBI) methodology. SPORTDiscus, MEDLINE, APA PsycInfo, and Embase databases were searched in English until 6 September 2022. The inclusion criteria were (1) coach(es) and/or support staff were explicitly questioned about their knowledge, perceptions, understanding, opinions, and/or applied practice of athlete monitoring; (2) results could be directly attributed to coach(es) and/or support staff; (3) primary research projects that are available as full-text. Exclusion criteria were applied for grey literature. The data were extracted into a custom-made data charting spreadsheet. From the 4381 identified records, 42 met the eligibility criteria. Almost all the studies were conducted within the Anglosphere and at the national or international level. The main reasons for coaches and support staff to implement athlete monitoring were to reduce injury and illness, inform the training program, and improve or maintain performance. While training load monitoring is generally seen as valuable the coaches and support staff acknowledged that there was no perfect scientific approach to monitoring athletes and believed it should be part of the bigger picture, emphasising communication. There has been a recent surge in research demonstrating that athlete monitoring extends beyond quantitative information and encompasses non-quantified subjective information. This further substantiates that coaches and support staff will remain central to athlete monitoring, even amidst the anticipated technological progress.

Competitive cyclists may be vulnerable to disordered eating (DE) and eating disorders (ED) due to perceived body composition optimisation and external influences within cycling culture and from stakeholders. Therefore, this study aimed to assess DE and ED risk in competitive cyclists using the Eating Attitudes Test (EAT-26), explore differences in responses based on sex, discipline and level of competition, and to gain insights into contributing factors towards DE via open-ended survey questions. In total, 203 participants completed a mixed-method questionnaire. Eating disorders were reported by 5.7% ( n = 11) of participants, with three being historic cases. The median (inter-quartile range) EAT-26 score was 8 (12) of a total possible score of 78. Disordered eating risk was observed in 16.7% of participants due to an EAT-26 score ≥20. Female participants had significantly higher scores than male participants (12.5 ± 17.5 vs. 6.5 ± 10.0; p = .004). There was no significant difference between road cyclists and off-road cyclists (7.0 ± 13.25 vs. 8.0 ± 10.5; p = .683). There was a significant difference in scores between novice/club/regional and national/elite/professional cyclists (6.0 ± 11.25 vs. 10.5 ± 12.0; p = .007). Thematic analysis of open-text responses found that the social environment of competitive cycling contributed towards DE behaviours and body image issues. These findings indicate competitive cyclists do appear to be an ‘at risk’ population for DE/ED. Therefore, there is need for stakeholders to enhance nutritional services, nutrition education and create supportive athlete environments.
竞技自行车运动员可能容易出现饮食紊乱（DE）和饮食失调（ED），原因是他们认为身体成分需要优化，以及自行车文化和利益相关者的外部影响。因此，本研究旨在使用饮食态度测试（EAT-26）评估竞技自行车运动员的饮食失调和进食障碍风险，探索基于性别、学科和竞技水平的反应差异，并通过开放式调查问题深入了解导致饮食失调的因素。共有 203 名参与者填写了混合方法问卷。5.7%的参与者（n = 11）报告了饮食失调，其中三人是历史病例。EAT-26 评分的中位数（四分位数间距）为 8（12）分，总分为 78 分。16.7%的参与者因EAT-26得分≥20分而有进食障碍的风险。女性参与者的得分明显高于男性参与者（12.5 ± 17.5 vs. 6.5 ± 10.0; p = .004）。公路自行车运动员和越野自行车运动员之间没有明显差异（7.0 ± 13.25 vs. 8.0 ± 10.5; p = .683）。新手/俱乐部/地区和国家/精英/专业自行车运动员之间的得分存在明显差异（6.0 ± 11.25 vs. 10.5 ± 12.0；p = .007）。对开放文本回复的主题分析发现，竞技自行车运动的社会环境导致了 DE 行为和身体形象问题。这些研究结果表明，竞技自行车运动员似乎是 DE/ED 的 "高危 "人群。因此，利益相关者有必要加强营养服务、营养教育和创造支持运动员的环境。

Therefore, there is need for stakeholders to enhance nutritional services, nutrition education and create supportive athlete environments.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"34 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971211","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 aimed to describe and analyse the disciplinary sanctions received by grassroots soccer coaches in the Valencian Community (Spain) over five seasons. Specific objectives included determining the influence of format (8-a-side or 11-a-side), age (U7, U9, U11, U13, U15, and U18), sex category (male or female), and sanction severity (mild [one to four matches] or serious [five matches to a full season]). A study was conducted based on referees’ records from 275,844 games played in 1401 league competitions during five subsequent seasons between 2014 and 2019 in Valencia (Spain). A total of 3563 sanctions were recorded by matchday referees, with the majority being minor offences (92.93%) and most being imposed on 11-a-side soccer coaches (87%). The most frequent reasons for sanctions pertained to protests to referees (28%); dismissal due to double reprimands (26.40%); contemptuous and inconsiderate attitudes towards referees, including insults and threats (19.53%); and direct sending-offs (8.84%). Significantly more mild sanctions were found than serious ones, with more sanctions emerging in the 11-a-side soccer than in the 8-a-side soccer and the men's category compared to the women's category. Finally, we found significantly more sanctions in the U18 men's category compared to all other younger age categories and in the U15 men's category compared to the U7, U9 and U9-U11 female categories (p < .05).

Elite cricket pace bowlers commonly sustain debilitating bone stress injuries. Lumbar bone stress injuries are more prominent in males, while lower limb bone stress injuries are more common in females. Bone stress injuries are partly attributable to bowling technique; however, scant research exists comparing bowling techniques of males and females as to better understand why males are more susceptible to lumbar bone stress injury. Three-dimensional pace bowling kinematics previously linked with lumbar bone stress injury were compared between 59 male and 19 female elite pace bowlers. Participants bowled 18 match-intensity deliveries indoors from a full run-up, whereby the mean of six deliveries was analyzed. Compared to females, males exhibited: a more extended thoraco-pelvic segment at back foot contact ( p = 0.039, g = 0.46), larger shoulder counter-rotation from back foot contact to front foot flat ( p = 0.021, g = 0.64), greater thoraco-pelvic lateral flexion at front foot flat ( p = 0.001, g = 0.95), larger front knee flexion at ball release ( p = 0.046, g = 0.57), and greater maximum front knee flexion from front foot flat to ball release ( p = 0.009, g = 0.57). Australian elite male pace bowlers performed techniques linked to lumbar bone stress injury to a much greater extent than their female counterparts. A straighter front leg technique observed in elite Australian females may be why they more commonly experience lower limb bone stress injuries via possibly higher vertical loading rates. This information may assist in developing sex-specific bone stress injury risk mitigation approaches.

Sporting success among nations provides a sense of value and national pride. This paper evaluated the perceptions and experiences of national coaches on the enablers and hindrances of international sporting success by elite athletes from historically disadvantaged areas (HDA) using the SPLISS framework. A qualitative research study design was employed for this study. Ten internationally recognised coaches (46.7 ± 12.9 years) volunteered for the study. Data was collected through semi-structured interviews. A thematic analysis was used to analyse data. Data was analysed using a computer software programme. Governance, organisation and sports policies, coach provision, local/international competition access, bursaries/scholarships and sport volunteerism were perceived as enablers, while lack of financial support, foundation level participation, school sport, athlete retention, sports facilities, reliable transport system and scientific support were perceived to be hindrances to sporting success. The findings highlight the need for policymakers to oversee and ensure a systemic governance approach with an integrated sports support system and effective policies, institutions and strategic planning, coupled with an adequate budget allocation in support of this system to facilitate elite sports success.
