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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"54 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142262664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"6 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142262666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"2 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142262665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"417 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"23 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"144 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
