Sport plays a crucial role in the health and wellbeing of young people. While positive outcomes from sports participation are often assumed, studies show that these depend significantly on coaches’ attitudes and behaviors, which shape the sporting environment and influence participants’ experiences and outcomes. This study provides a systematic review with meta-analysis of various coach education program interventions (CEPIs), aiming to answer the question: How do CEPIs impact coaching effectiveness compared to standard coaching practices without such programs? Analyzing a total of 45 studies ( N = 180,658), this systematic review is divided into a narrative section followed by a meta-analysis. Positive effects of CEPIs were observed in 78% of the studies, seen in coaches’ knowledge gain, attitude shifts, and behavioral changes, as well as in athletes’ physical and psychological outcomes, both within and outside of sport. Overall, a significant moderate to large effect of CEPIs on coaching effectiveness ( g = 0.47, k = 264, 95% CI [0.36, 0.59]) was noted. Specifically, a large overall effect on coach outcomes ( g = 0.73, k = 71, 95% CI [0.47, 1.00]) and a moderate to large overall effect on athlete outcomes ( g = 0.38, k = 193, 95% CI [0.28, 0.47]) were observed. These findings generally support the positive impact of CEPIs on coaching effectiveness across the reviewed studies. However, the effects varied in magnitude, scalability, and sustainability for coaches and athletes. The discussion focuses on insights derived from CEPIs and future improvement strategies.
体育运动对青少年的健康和福祉起着至关重要的作用。虽然人们通常认为参与体育运动会产生积极的结果,但研究表明,这些结果在很大程度上取决于教练的态度和行为,而教练的态度和行为会塑造体育环境,影响参与者的体验和结果。本研究对各种教练教育计划干预措施(CEPIs)进行了系统回顾和荟萃分析,旨在回答以下问题:与没有此类项目的标准教练实践相比,CEPIs 如何影响教练的有效性?本系统综述共分析了 45 项研究(N = 180658),分为叙述部分和荟萃分析部分。在 78% 的研究中观察到了 CEPIs 的积极效果,这些效果体现在教练员的知识增长、态度转变和行为改变,以及运动员在运动内外的生理和心理结果。总体而言,CEPIs 对教练有效性有明显的中度至高度影响(g = 0.47,k = 264,95% CI [0.36,0.59])。具体而言,对教练效果的总体影响较大(g = 0.73,k = 71,95% CI [0.47,1.00]),对运动员效果的总体影响中等至较大(g = 0.38,k = 193,95% CI [0.28,0.47])。这些研究结果普遍支持 CEPIs 对所审查研究中的教练有效性产生积极影响。然而,这些影响在程度、可扩展性以及对教练员和运动员的可持续性方面各不相同。讨论的重点是从 CEPIs 中得到的启示以及未来的改进策略。

The recent rise in professionalisation and institutionalisation of competitive surfing has resulted in a dramatic increase in the use of alternative training modalities. These are often employed in an attempt to increase exposure to surf-like activities when appropriate ocean conditions are not available. It is commonly accepted that practice sessions should be grounded in theory, with training content informed by a clear scientific rationale. Despite this, research is yet to offer surfing coaches and surfers effective strategies to assist in implementing appropriate ‘off water’ training modalities. It is widely accepted that integrating a representative learning design is crucial towards the transfer of performance to competition environments. Therefore, the aim of this paper is to promote representative learning design (RLD) as a contemporary, principled framework that can underpin the creation of surfing training design and performance. Examples of constraints relevant to surfing are considered, and the efficacy and rationale of popular training methods are challenged. Finally, practical implications and coaching tools to underpin the implementation of representative learning design in surf training are provided.
近年来,冲浪竞技的专业化和制度化程度不断提高,导致替代训练模式的使用急剧增加。在没有适当海洋条件的情况下,这些训练方式往往是为了增加接触类似冲浪活动的机会。人们普遍认为,练习课程应以理论为基础,训练内容要有明确的科学依据。尽管如此,研究还没有为冲浪教练和冲浪者提供有效的策略,以帮助他们实施适当的 "水外 "训练模式。人们普遍认为,整合具有代表性的学习设计对于将成绩转移到比赛环境中至关重要。因此,本文旨在推广代表性学习设计 (RLD),将其作为一个当代的原则性框架,为冲浪训练设计和成绩的创造提供支持。本文列举了与冲浪运动相关的制约因素,并对流行训练方法的有效性和合理性提出了质疑。最后,还提供了在冲浪培训中实施代表性学习设计的实际意义和指导工具。

Sports coaching involves navigating ambiguity and uncertainty in stakeholders’ perspectives and managing a dynamic micro-political environment. This study explores the relationship between coaching efficacy and effectiveness in South African Women's Rugby. It examines how a coach's belief in their ability to influence athlete learning and performance (coaching efficacy) correlates with the actual impact on athletes (coaching effectiveness). By aligning coaches’ perceived competence with tangible athlete outcomes, the study provides insights into factors influencing coaching practices and athlete development. The study involved 28 women players (mean age: 24.8 ± 4.0 years) and 8 coaches (mean age: 41 ± 3.8 years) who participated in semi-structured online interviews. The interview script, derived from the Coaching Effectiveness Survey (CES) tool, was analysed using Braun and Clarke's 6-step process of thematic content analysis. Under the four efficacy dimensions, sub-themes emerged as follow: 1) motivation (climate created by the coach and a motivational climate experienced by the players), 2) technique (coaching physical, technical, and tactical aspects of rugby), 3) game strategy (guiding players to successful outcomes), and 4) character-building efficacy (cultivating a positive environment for sportswomanship and holistic development). The findings incorporate feedback from players and coaches, highlighting firsthand experiences of coaching effectiveness. This approach enables experts to identify effective coaching strategies and those needing refinement within Women's Rugby. The study's findings promise to inform future coach development frameworks and foster a comprehensive understanding of coaching effectiveness in the dynamic landscape of Women's Rugby worldwide.
体育教练需要在利益相关者观点的模糊性和不确定性中游刃有余,并管理动态的微观政治环境。本研究探讨了南非女子橄榄球运动中教练的效能与效率之间的关系。研究探讨了教练对其影响运动员学习和表现的能力的信念(教练效能)与对运动员的实际影响(教练效能)之间的关系。通过将教练员感知的能力与运动员的实际成果相联系,该研究深入探讨了影响教练实践和运动员发展的因素。研究涉及 28 名女选手(平均年龄:24.8 ± 4.0 岁)和 8 名教练员(平均年龄:41 ± 3.8 岁),她们参加了半结构化在线访谈。访谈脚本来自教练效能调查(CES)工具,采用布劳恩和克拉克的六步主题内容分析法进行分析。在四个效能维度下,出现了以下子主题:1)动力(教练营造的氛围和球员体验到的动力氛围),2)技术(橄榄球的体能、技术和战术方面的指导),3)比赛策略(指导球员取得成功),以及 4)性格塑造效能(为体育精神和全面发展营造积极的环境)。研究结果纳入了球员和教练的反馈意见,强调了教练有效性的第一手经验。通过这种方法,专家们可以确定在女子橄榄球运动中有效的教练策略和需要改进的策略。研究结果有望为未来的教练发展框架提供信息,并促进对全球女子橄榄球动态环境中教练有效性的全面了解。

Coaching leadership greatly impacts athletes’ mental health and wellbeing. Although research shows a positive link between authentic leadership and athlete satisfaction, studies on specific subdimensions are limited. This study examines the influence of authentic leadership on athlete engagement and performance, utilizing a conditional process model to explore the mediating effects of psychological ownership and athlete engagement. A survey of 381 athletes (274 male, 107 female; Mage = 19.98; SD = 2.48) from team and individual sports found that perceived authentic leadership positively correlates with training competition satisfaction, psychological ownership, and athlete engagement. Structural equation modeling revealed that psychological ownership and athlete engagement significantly mediate this relationship. Thus, authentic leadership directly and indirectly enhances athletes’ satisfaction.
教练的领导力对运动员的心理健康和幸福感有很大影响。尽管研究表明,真实领导力与运动员满意度之间存在积极联系,但针对特定子维度的研究却十分有限。本研究探讨了真实领导力对运动员参与度和表现的影响,利用条件过程模型来探索心理所有权和运动员参与度的中介效应。对 381 名团体和个人运动项目的运动员(274 名男性,107 名女性;平均年龄 = 19.98;平均标准偏差 = 2.48)进行的调查发现,感知到的真实领导力与训练比赛满意度、心理所有权和运动员参与度呈正相关。结构方程模型显示,心理所有权和运动员参与度在很大程度上调节了这种关系。因此,真实领导力直接或间接地提高了运动员的满意度。

Six world-class Chinese male rowers (age: 28.2 ± 3.2 years; height: 1.93 ± 0.02 m; body mass: 94.7 ± 3.9 kg) participated in the study. The training volume in different modalities and intensities were recorded over 44 weeks. To evaluate rowing performance, rowers completed four 2000 m and 5000 m maximum effort time trials and two incremental step tests. Total training time for the season was 907 h, which consisted of 67.5% of rowing training, 16.9% of strength training, 15.2% of warm-up and flexibility, and 0.4% of non-specific endurance training. The rowing training intensity distribution (TID) was 87.0% performed at low intensity (LIT), 8.4% at moderate intensity (MIT), and 4.6% at high intensity (HIT). There was no significant difference in average weekly rowing training volume (distance) at LIT across four phases (p = 0.12), as well as rowing training at MIT (p = 0.07) and HIT (p = 0.97). The fourth 2000 m time trials performance significantly improved from the first trial (−6.4 s, p = 0.02). The fourth 5000 m time trial performance was significantly improved from the first (−13.4 s, p = 0.02) and second trial (−14.1 s, p = 0.01). The final-step mean power output (W) in the second incremental step test improved significantly (p = 0.04). In the 2018–19 season, China's world-class rowers conducted considerable LIT rowing. The training volume distribution and rowing TID were similar in all phases.
六名世界级的中国男子赛艇运动员(年龄:28.2 ± 3.2 岁;身高:1.93 ± 0.02 米;体重:94.7 ± 3.9 千克)参与了这项研究。在 44 周内记录了不同模式和强度的训练量。为了评估赛艇成绩,赛艇运动员完成了四次 2000 米和 5000 米最大努力计时赛和两次增量步测试。赛季总训练时间为 907 小时,其中划船训练占 67.5%,力量训练占 16.9%,热身和柔韧性训练占 15.2%,非特异性耐力训练占 0.4%。划船训练强度分布(TID)为:87.0%为低强度(LIT),8.4%为中等强度(MIT),4.6%为高强度(HIT)。四个阶段中,低强度(LIT)每周平均划船训练量(距离)(p = 0.12)与中强度(MIT)(p = 0.07)和高强度(HIT)划船训练量(距离)(p = 0.97)无明显差异。第四次 2000 米计时赛的成绩与第一次相比有明显提高(-6.4 秒,p = 0.02)。第四次 5000 米计时赛成绩比第一次(-13.4 秒,p = 0.02)和第二次(-14.1 秒,p = 0.01)有明显提高。第二次增步测试的最后一步平均功率输出(W)明显提高(p = 0.04)。2018-19赛季,中国的世界级赛艇运动员进行了大量的LIT赛艇训练。各阶段的训练量分布和赛艇TID相似。

Objectivity of match analysis in football: Testing the level of agreement between coaches’ interpretations of video data 足球比赛分析的客观性:测试教练员对视频数据解读的一致程度
IF 1.9 4区 教育学 Q3 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-09-05 DOI: 10.1177/17479541241278603

Using video data is a widespread procedure in the preparation for an upcoming opponent across all levels of football, but the way coaches interpret this data and use it for player feedback is still not fully understood. Three studies were conducted to investigate the level of agreement between football coaches on tactical questions regarding the opponent when interpreting the same video data. In Study 1 (scouting feed; N = 15) and 2 (tactic view feed; N = 24), different video viewing angles of the same match were provided to coaches, followed by simple questions regarding the viewed team (e.g., team formation, most striking player in the opening play of the attacking team). Response analyses using descriptive statistics and Fleiss-Kappa statistics showed great diversity regardless of the angle of the feed. Study 3 was a replication study (scouting feed; N = 16) using the identical approach as before but used a different match to introduce greater variety of video stimuli. Across all studies there was a high degree of diversity in coach responses and little consensus on basic questions like the adopted formation or the most striking player in the opening play (Fleiss-Kappa coefficients between -.036 [poor agreement] and .236 [fair agreement]). The present research shows that it is problematic to treat information from video feeds as being objective when preparing for the next opponent, as different coaches derive different interpretations from the same data source. Implications for use of video data, and related contributions to coaching research are discussed.
在各级足球比赛中,使用视频数据是为即将到来的对手做准备的一个普遍程序,但教练如何解读这些数据并将其用于球员反馈仍未得到充分理解。我们进行了三项研究,以调查足球教练在解读相同视频数据时,就对手战术问题达成一致的程度。在研究 1(球探资料;N = 15)和研究 2(战术视图资料;N = 24)中,向教练提供了同一场比赛的不同视频观看角度,随后提出了有关所观看球队的简单问题(如球队阵型、进攻球队开场最引人注目的球员)。使用描述性统计和 Fleiss-Kappa 统计进行的反应分析表明,无论从哪个角度观看,结果都有很大差异。研究 3 是一项重复研究(球探馈送;N = 16),采用了与之前相同的方法,但使用了不同的比赛以引入更多的视频刺激。在所有研究中,教练的回答都存在很大的差异,而且在采用何种阵型或开场最引人注目的球员等基本问题上几乎没有共识(Fleiss-Kappa系数介于-.036[较差一致]和.236[一般一致]之间)。本研究表明,在备战下一个对手时,将视频资料视为客观信息是有问题的,因为不同的教练会从相同的数据源得出不同的解释。本研究讨论了使用视频数据的意义以及对教练研究的相关贡献。

This study compared traditional rugby union (RU) games to a modified small-sided game (SSG) aimed at improving opportunity for physical activity and enjoyment in children. Twenty-six school rugby players (aged 10 y) played 10 RU matches. Five traditional games on a full-sized field with 10–12 players per team and five SSG on a modified field with seven players per team. Movement patterns, enjoyment, involvements (e.g., possessions, passes, tackles, rucks and tries), and heart rate (HR) were recorded. Session rating of perceived exertion (sRPE) was measured at the end of each game and used to calculate game load (sRPE x duration). Significance was set at p ≤ 0.05. Individuals covered greater distances (total, low and high speed) overall and relatively (per min) and had higher HR whilst playing traditional format RU. Despite covering greater distances, perceived exertion and game load were similar and importantly, enjoyment was high for both game formats. Individual player match involvements (overall and relative possessions and passes, and relative tackles) were higher in SSG. Given that players enjoyed both game formats, movement pattern and physiological data suggest traditional games may be more suitable for improving physical activity and fitness, while individual involvement data suggest SSG may be more suitable for improving opportunities for participation and skill development.
本研究将传统的橄榄球联盟(RU)比赛与改良的小场比赛(SSG)进行了比较,旨在提高儿童体育锻炼的机会和乐趣。26 名学校橄榄球运动员(10 岁)参加了 10 场橄榄球比赛。其中五场是在全尺寸场地上进行的传统比赛,每队 10-12 人;五场是在改良场地上进行的小型比赛,每队 7 人。对运动模式、乐趣、参与度(如控球、传球、拦截、抢断和达阵)和心率(HR)进行了记录。在每场比赛结束时测量感知消耗量(session rating of perceived exertion,sRPE),用于计算比赛负荷(sRPE x 持续时间)。显著性设定为 p≤ 0.05。在进行传统形式的 RU 时,个人的总距离(总距离、低速距离和高速距离)和相对距离(每分钟)更长,心率更高。尽管距离更远,但感觉到的消耗和比赛负荷相似,重要的是,两种比赛形式的乐趣都很高。在 SSG 比赛中,球员的个人比赛参与度(总体和相对控球和传球以及相对拦截)更高。鉴于球员们对这两种比赛形式都很喜欢,运动模式和生理数据表明,传统比赛可能更适合提高身体活动和体能,而个人参与数据表明,SSG 可能更适合提高参与机会和技能发展。

Exploring the relationship between coach-initiated motivational climate and athlete well-being, resilience, and psychological safety in competitive sport teams 探索竞技运动队中教练发起的激励氛围与运动员幸福感、恢复力和心理安全之间的关系
IF 1.9 4区 教育学 Q3 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-08-29 DOI: 10.1177/17479541241278602

The purpose of this study was to investigate coach-initiated motivational climate and its relationship with athlete well-being, resilience, and psychological safety in competitive sport. In addition to independent relationships between task- and ego-related climates and the study outcomes, this research also explored the potential additive effects of task and ego climate together to understand if a task climate can buffer against the negative impacts of an ego climate. Self-report survey data were collected from competitive soccer players across Ontario, Canada ( N = 298; Mage = 20.38; 58.72% male). Using multiple linear regression, a perceived task-related climate was a significant positive predictor of well-being ( ß = .33), resilience ( ß = .31), and psychological safety ( ß = .54, all ps < .001). A higher perceived ego-related climate was a significant negative predictor of psychological safety ( ß = −.23, p < .001), and not significantly related to well-being and resilience. Partial support for the additive effect of task- and ego-related climate together was found for psychological safety, but not well-being or resilience. Specifically, athletes in the latent profile characterized by average task and higher ego scored higher on psychological safety compared with lower task and higher ego climate perceptions. The increase in psychological safety between these two profiles was observed despite both having higher ego-related climates. Although future research is required, the findings offer meaningful contributions to theory and practice in the context of competitive soccer teams.
本研究的目的是调查在竞技体育中由教练引发的激励氛围及其与运动员的幸福感、恢复力和心理安全之间的关系。除了与任务和自我相关的氛围与研究结果之间的独立关系外,本研究还探讨了任务和自我氛围的潜在叠加效应,以了解任务氛围是否能缓冲自我氛围的负面影响。研究收集了加拿大安大略省竞技足球运动员的自我报告调查数据(人数 = 298;年龄 = 20.38;58.72% 为男性)。通过多元线性回归,感知到的与任务相关的氛围对幸福感( ß = .33)、复原力( ß = .31)和心理安全( ß = .54, all ps < .001)有显著的正向预测作用。较高的自我相关氛围对心理安全有显著的负向预测作用(ß = -.23, p <.001),但与幸福感和复原力的关系不大。在心理安全方面,任务和自我相关氛围的叠加效应得到了部分支持,但在幸福感和复原力方面却没有得到支持。具体地说,与低任务和高自我气候感知的运动员相比,潜在特征为平均任务和高自我的运动员在心理安全方面得分更高。尽管这两种情况下的运动员都具有较高的自我相关氛围,但这两种情况下的运动员的心理安全感都有所提高。虽然未来的研究还需要继续,但这些发现为足球竞技团队的理论和实践提供了有意义的贡献。

Although paddling has been widely studied, there remains a limited understanding of how a surfer's paddling ability directly influences their wave-riding performance. Using an ecological approach, this study examined the importance of paddling to surfing performance from the perspective of elite Australian athletes, coaches, and performance support practitioners. Ten elite Australian surfing coaches, ten elite Australian surfing athletes, and eight performance support practitioners completed semi-structured interviews. This approach underscores the significance of incorporating experiential knowledge from coaches, athletes, and performance support practitioners, particularly in surfing where the nature of high-performance sport requires a multi-disciplinary approach and highlights the potential value of qualitatively exploring expert perspectives. Findings showed that all participants agree that paddling is an integral aspect of surfing performance despite not being directly scored in competition. The ecological dynamics approach provided a framework for understanding the function of paddling as a tool that enables surfers to exploit the affordances of the environment and support positive performance outcomes under highly variable conditions. The findings highlight the complexities of the performer-environment relationship in surfing and draw attention to the potential for improvements in surfing performance that may be elicited by enhancing a surfer's paddling ability. This study contributes to a growing body of sports science literature investigating paddling performance in surfers and underscores the importance of paddling to surfing performance.
尽管划水已被广泛研究,但人们对冲浪者的划水能力如何直接影响其冲浪成绩的了解仍然有限。本研究采用生态学方法,从澳大利亚冲浪精英运动员、教练员和运动表现支持从业人员的角度考察了划水对冲浪表现的重要性。十名澳大利亚冲浪精英教练、十名澳大利亚冲浪精英运动员和八名成绩支持从业人员完成了半结构化访谈。这种方法强调了从教练、运动员和成绩支持从业人员那里获得经验知识的重要性,尤其是在冲浪运动中,因为高性能运动的性质要求采用多学科方法,并突出了定性探索专家观点的潜在价值。研究结果表明,所有参与者都认为划水是冲浪运动成绩不可或缺的一个方面,尽管在比赛中并不直接计分。生态动力学方法为理解划水的功能提供了一个框架,划水作为一种工具,使冲浪者能够利用环境的承受能力,并在高度多变的条件下支持积极的表现结果。研究结果凸显了冲浪运动中运动员与环境关系的复杂性,并提请人们注意通过提高冲浪运动员的划水能力来提高冲浪成绩的潜力。这项研究为越来越多的研究冲浪者划水表现的体育科学文献做出了贡献,并强调了划水对冲浪表现的重要性。

The Technical-Tactical Profile of Soccer Goalkeepers: The Impact of age and Competitive Level 足球守门员的技术战术概况:年龄和竞技水平的影响
IF 1.9 4区 教育学 Q3 HOSPITALITY, LEISURE, SPORT & TOURISM Pub Date : 2024-08-28 DOI: 10.1177/17479541241275914

The aim of the study was to evaluate the technical-tactical requirements profile of goalkeepers and to assess the influence of age and performance level. Therefore, 213 league matches involving elite youth soccer players (under 17 years old [U17], U19), semi-professional (U23, Germany's 4th league), and professional teams (Germany's 1st and 2nd league) were analyzed. Goalkeeper actions related to distribution, space defense, and goal defense were qualitatively recorded using a predefined categorization system by two independent raters, ensuring rigorous examination. The distribution of actions across offensive play, space defense, and goal defense was consistent, indicating robust patterns regardless of age or competitive level. Specifically, offensive play actions constituted about 73–77% of all actions, space defense accounted for 13–15%, and goal defense comprised 10–12%. This uniformity suggests that despite variations in age and competitive levels, the technical requirements profiles of U17, U19, U23, and professional goalkeepers largely coincide. Consequently, goalkeepers should be introduced to building play under pressure as early as possible. Training focused on playing with the feet under pressure should hold a high priority in goalkeeper training.
研究的目的是评估守门员的技术战术要求概况,并评估年龄和表现水平的影响。因此,研究人员分析了 213 场涉及精英青少年足球运动员(17 岁以下 [U17]、U19)、半职业球队(U23、德国第四级别联赛)和职业球队(德国第一和第二级别联赛)的联赛。门将在分球、空间防守和球门防守方面的动作由两名独立评分员使用预定义的分类系统进行定性记录,以确保检查的严谨性。进攻、空间防守和球门防守的动作分布是一致的,这表明无论年龄或竞技水平如何,都有很强的规律性。具体来说,进攻战术动作约占所有动作的 73-77%,空间防守占 13-15%,球门防守占 10-12%。这种一致性表明,尽管年龄和竞技水平存在差异,但 U17、U19、U23 和职业门将的技术要求基本一致。因此,应尽早让门将在压力下训练。在守门员训练中,应高度重视以压力下用脚踢球为重点的训练。
