Inclusive and equitable processes are important to the development of sports coaching. The aim of this study was to explore how well UK coach education meets the needs of women sports coaches in order to make recommendations to further enhance the engagement of, and support for, aspiring and existing women coaches. The national governing bodies (NGBs) of four sports (Cycling, Equestrian, Gymnastics and Rowing) volunteered to participate and semi-structured interviews using the tenants of Appreciative Inquiry (AI) within a Self Determination Theory (SDT) framework were undertaken with 23 coaches, eight coach educators and five NGB officers. The data themed into an analytic structure derived from SDT comprising ‘Autonomy: Freedom to coach’, ‘Coaching competence’, and ‘Relatedness and belonging’. The coaches perceived potential benefit from enhanced relatedness and belonging within their sport with the findings suggesting that NGBs should embrace coach-led decision making in terms of the developmental topics which are important and should adopt the development of competence, rather than assessing technical understanding, as the foundational principle of more inclusive coach education. Future research should investigate the impact of the inclusive practices which are recommended within this investigation such as the softening of the technocratic focus of formal coach education.

Résumé : L’entrainement sportif est « un processus de perfectionnement de l’athlète dirigé selon des principes scientifiques et qui, par des influences planifiées et systématiques (charges) sur la capacité de performance, vise à mener le sportif vers des performances élevées et supérieures dans un sport ou une discipline sportive » (Harre, 1982). Un entrainement sportif approprié devrait commencer dès l’enfance. Ainsi, le jeune sportif pourrait progressivement et systématiquement développer son corps et son esprit afin d’atteindre l’excellence sportive (Bompa, 2000; Weineck, 1997). Or plusieurs entraineurs, dans leur tentative de parvenir à des résultats de haut niveau rapidement, exposent les jeunes athlètes à une formation sportive très spécifique et rigoureuse, sans prendre le temps de développer convenablement les aptitudes physiques et motrices et les habiletés motrices fondamentales sous-jacentes aux habiletés sportives spécifiques (Bompa, 2000), d’où l’appellation « spécialisation hâtive ». Afin de contrer les conséquences néfastes de la spécialisation hâtive, de nouvelles approches d’entrainement ont été proposées. Une des façons d’y arriver consisterait notamment à pratiquer différents sports en bas âge (Fraser-Thomas, Côté et Deakin, 2008; Gould et Carson, 2004; Judge et Gilreath, 2009; LeBlanc et Dickson, 1997; Mostafavifar, Best et Myer, 2013), d’où l’appellation « diversification sportive ». Plusieurs organisations sportives et professionnelles ont décidé de valoriser et de mettre en place des programmes basés sur la diversification sportive (Kaleth et Mikesky, 2010). C’est donc à la suite d’une prise de conscience des effets néfastes de la spécialisation hâtive que des professionnels de l’activité physique d’une école secondaire du Québec (éducateur physique, kinésiologue et agent de développement sportif) ont mis en place un programme multisports-études novateur au premier cycle du secondaire, inspiré des sciences du sport et des lignes directrices du modèle de développement à long terme de l’athlète (DLTA) (Balyi, Cardinal, Higgs, Norris et Way, 2005). Le présent projet de recherche porte sur le développement des aptitudes physiques et motrices chez de jeunes sportifs inscrits à un programme de spécialisation sportive et de jeunes sportifs inscrits à un programme de diversification sportive à l’étape « S’entrainer à s’entrainer » (12 à 16 ans) du modèle de développement à long terme de l’athlète (Balyi et al., 2005). L’objectif principal de cette étude est de rendre compte de l’évolution des aptitudes physiques et motrices de jeunes élèves-athlètes inscrits, d’une part, à un programme sport-études soccer (spécialisation) et, d’autre part, à un programme multisports-études (diversification). Plus spécifiquement, cette étude tente de (a) dresser un portrait détaillé de l’évolution des aptitudes physiques et motrices des élèves-athlètes de chaque programme et de faire un parallèle avec la planification annuelle de chaque programme sportif et (b) de rendre compte des différences d’aptitudes physiques et motrices observées entre les deux programmes. Le projet de recherche a été réalisé dans une école secondaire de la province de Québec. Au total, 53 élèves-athlètes de première secondaire ont été retenus pour le projet de recherche selon leur volonté de participer à l’étude, soit 23 élèves-athlètes de première secondaire inscrits au programme sport-études soccer et 30 élèves-athlètes de première secondaire inscrits au programme multisports-études. Les élèves-athlètes étaient tous âgés de 11 à 13 ans. Treize épreuves standardisées d’aptitudes physiques et motrices ont été administrées aux élèves-athlètes des deux programmes sportifs en début, en milieu et en fin d’année scolaire. Le traitement des données s’est effectué à l’aide de statistiques descriptives et d’une analyse de variance à mesures répétées. Les résultats révèlent que (a) l’ensemble des aptitudes physiques et motrices des élèves-athlètes des deux programmes sportifs se sont améliorées au cours de l’année scolaire, (b) il est relativement facile de faire un parallèle entre l’évolution des aptitudes physiques et motrices des élèves-athlètes et la planification annuelle de chaque programme sportif, (c) les élèves-athlètes du programme multisports-études ont, en général, des performances semblables à celles des élèves-athlètes du programme sport-études soccer et (d) les élèves-athlètes du programme sport-études soccer ont, au cours de l’année scolaire, amélioré davantage leur endurance cardiorespiratoire, alors que ceux du programme multisports-études ont amélioré davantage (a) leur vitesse segmentaire des bras, (b) leur agilité à l’épreuve de course en cercle et (c) leur puissance musculaire des membres inférieurs, confirmant ainsi que les aptitudes physiques et motrices développées chez de jeunes athlètes qui se spécialisent tôt sont plutôt spécifiques au sport pratiqué (Balyi et al., 2005; Bompa, 1999; Cloes, Delfosse, Ledent et Piéron, 1994; Mattson et Richards, 2010), alors que celles développées à travers la diversification sportive sont davantage diversifiées (Coakley, 2010; Gould et Carson, 2004; White et Oatman, 2009). Ces résultats peuvent s’expliquer par (a) la spécificité ou la diversité des tâches proposées durant les séances d’entrainement, (b) le temps consacré à chacune de ces tâches et (c) les exigences reliées à la pratique du soccer comparativement aux exigences reliées à la pratique de plusieurs disciplines sportives. Toutefois, les résultats obtenus restent complexes à interpréter en raison de différents biais : (a) la maturation physique, (b) le nombre d’heures d’entrainement effectué au cours de l’année scolaire précédente, (c) le nombre d’heures d’entrainement offert par les deux programmes sportifs à l’étude et (d) les activités physiques et sportives pratiquées à l’extérieur de l’école. De plus, cette étude ne permet pas d’évaluer la qualité des interventions et des exercices proposés lors des entrainements ni la motivation des élèves-athlètes à prendre part aux séances d’entrainement ou aux épreuves physiques et motrices. Finalement, il serait intéressant de reprendre la présente étude auprès de disciplines sportives différentes et de mettre en évidence les contributions particulières de chaque discipline sportive sur le développement des aptitudes physiques et motrices de jeunes athlètes.

With the world of professional sports shifting towards employing better sport analytics, the demand for vision-based performance analysis is growing increasingly in recent years. In addition, the nature of many sports does not allow the use of any kind of sensors or other wearable markers attached to players for monitoring their performances during competitions. This provides a potential application of systematic observations such as tracking information of the players to help coaches to develop their visual skills and perceptual awareness needed to make decisions about team strategy or training plans. My PhD project is part of a bigger ongoing project between sport scientists and computer scientists involving also industry partners and sports organisations. The overall idea is to investigate the contribution technology can make to the analysis of sports performance on the example of team sports such as rugby, football or hockey. A particular focus is on vision-based tracking, so that information about the location and dynamics of the players can be gained without any additional sensors on the players. To start with, prior approaches on visual tracking are extensively reviewed and analysed. In this thesis, methods to deal with the difficulties in visual tracking to handle the target appearance changes caused by intrinsic (e.g. pose variation) and extrinsic factors, such as occlusion, are proposed. This analysis highlights the importance of the proposed visual tracking algorithms, which reflect these challenges and suggest robust and accurate frameworks to estimate the target state in a complex tracking scenario such as a sports scene, thereby facilitating the tracking process. Next, a framework for continuously tracking multiple targets is proposed. Compared to single target tracking, multi-target tracking such as tracking the players on a sports field, poses additional difficulties, namely data association, which needs to be addressed. Here, the aim is to locate all targets of interest, inferring their trajectories and deciding which observation corresponds to which target trajectory is. In this thesis, an efficient framework is proposed to handle this particular problem, especially in sport scenes, where the players of the same team tend to look similar and exhibit complex interactions and unpredictable movements resulting in matching ambiguity between the players. The presented approach is also evaluated on different sports datasets and shows promising results. Finally, information from the proposed tracking system is utilised as the basic input for further higher level performance analysis such as tactics and team formations, which can help coaches to design a better training plan. Due to the continuous nature of many team sports (e.g. soccer, hockey), it is not straightforward to infer the high-level team behaviours, such as players’ interaction. The proposed framework relies on two distinct levels of performance analysis: low-level performance analysis, such as identifying players positions on the play field, as well as a high-level analysis, where the aim is to estimate the density of player locations or detecting their possible interaction group. The related experiments show the proposed approach can effectively explore this high-level information, which has many potential applications.

In support of the achievement goal theory (AGT), empirical research has demonstrated psychosocial benefits of the mastery-oriented learning climate. In this study, we examined the effects of perceived coaching behaviors on various indicators of psychosocial well-being (competitive anxiety, self-esteem, perceived competence, enjoyment, and future intentions for participation), as mediated by perceptions of the coach-initiated motivational climate, achievement goal orientations and perceptions of sport-specific skills efficacy. Using a pre-post test design, 1,464 boys, ages 10-15 (M = 12.84 years, SD = 1.44), who participated in a series of 12 football skills clinics were surveyed from various locations across the United States. Using structural equation modeling (SEM) path analysis and hierarchical regression analysis, the cumulative direct and indirect effects of the perceived coaching behaviors on the psychosocial variables at post-test were parsed out to determine what types of coaching behaviors are more conducive to the positive psychosocial development of youth athletes. The study demonstrated that how coaching behaviors are perceived impacts the athletes’ perceptions of the motivational climate and achievement goal orientations, as well as self-efficacy beliefs. These effects in turn affect the athletes’ self-esteem, general competence, sport-specific competence, competitive anxiety, enjoyment, and intentions to remain involved in the sport. The findings also clarify how young boys internalize and interpret coaches’ messages through modification of achievement goal orientations and sport-specific efficacy beliefs.

This study aimed to detect and analyse regular patterns of play in fast attack of football teams, through the combination of the sequential analysis technique and semi-structured interviews to experienced first League Portuguese coaches. The sample included 36 games (12 games of the respective national leagues per team) of the F.C. Barcelona, Inter Milan, and Manchester United teams that were coded with the observational instrument tool developed by Sarmento et al. (2010) and the data analysed through sequential analysis with the software SDIS-GSEQ 5.0. Based on the detected patterns, semi-structured interviews were carried out to 8 expert high-performance football coaches and data were analysed through the content analysis technique using the software NVivo 10. The detected patterns of play revealed specific characteristics of the teams under study. The combination of the results of sequential analysis with the qualitative interviews to the professional coaches proved to be very fruitful in this game the analysis of scope, allowing reconcile scientific knowledge with practical interpretation of coaches who develop their tasks in the field.

Background: Sport is a compulsory activity in schools in South Africa. Female learners participating in soccer are more vulnerable to injuries than males. Objective: This study determined the epidemiology of injuries in female high school soccer players. Methods: A cross sectional survey captured the epidemiology of injuries in the players. The population included 200 players from 27 high schools in one district between the ages of 14 to 19 years. A self-administered questionnaire was used to collect data. Results: Only 85 scholars from 8 schools participated. From the 85 respondents, 31 (36.5%) sustained injuries. Only 61 injuries were reported by the injured players. The injury prevalence for the season was 36.5%. The rate of injury was 90 per 1000 athlete exposure hours during the season. The defenders and midfielders sustained the most injuries. Most injuries reported were contact in nature. More injuries occurred during training than during matches. The lower extremity (77.8%) was injured more than the upper extremity (22.2%). The knee (22.2%) and ankle (15.9%) were the most frequently injured body parts. Muscle injury was the most commonly reported followed by bruising. Conclusion: Prevalence of injuries was high with the lower limb, specifically the knee and ankle being commonly injured.

Las lesiones musculares del muslo tienen una gran incidencia en el fútbol. El objetivo del estudio ha sido desarrollar un nuevo procedimiento para evaluar el efecto de las lesiones de isquiotibiales en los golpeos con el pie s en el fútbol utilizando los principios de la dinámica inversa. El trabajo se ha centrado en la evaluación de la diferencia entre sujetos que habían sufrido la lesión en los últimos 5 años y los que no. Se analizaron 17 jugadores de fútbol profesionales realizando cinco tiros con el empeine y cinco con el interior del pie. Los movimientos se registraron mediante una plataforma de fuerza y un sistema de captura de movimiento Vicon funcionando a 500Hz. Los participantes también tomaron parte en una prueba de isocinético en la que se midió el torque isocinético en 60 º/s y 120 º/s. Se observaron diferencias significativas en los parámetros cinemáticos y cinéticos entre los dos grupos (lesionados y no lesionados) en la fase posterior del golpeo y en el instante de máxima flexión de cadera. No se encontraron diferencias significativas entre los dos grupos en la prueba isocinética tradicional. Estos resultados indican que el procedimiento empleado probablemente podría ser muy útil en la evaluación del efecto de las lesiones de isquiotibiales en el fútbol.

Our work in this research is to capture the value judgments in the discourse of the website Globoesporte.com on representing the Brazil National Football Team during the 2010 FIFA World Cup. We have checked how the team is overrated by the website, submitted to the editorial line of Globo Organizations which is especially optimistic about the national football. The analysis was based on the relation between the texts and the information we have access to and the theoretical assumptions. It seems obvious for us that, because of the emotional bond with the country, the Brazil National Football Team gets more attention from the website.
