The nearly useless hel- mets we wore had way-too-thin ear pads and faceplates that barely protected us from the sharp debris and swirling dust. ...we were in a mini-windstorm inside a bus filled with ...dead people's dust. The rats were fearless, vicious and carried disease our mea- gre antibiotics couldn't fight.
The essay does not provide a final answer to the question of its subtitle, but it juxtaposes the profiles of Michael Laudrup and Zlatan Ibrahimović in terms of soccer abilities, career statistics and ...social backgrounds. While arguing that comparisons between soccer players are in principle meaningless, the essay nevertheless employs comparison heuristically in order to outline each player's uniqueness through differences and similarities. If Laudrup and Ibrahimović are considered to be the best ever soccer players of Scandinavia, sharing traits of technical brilliance and postmodern nomadism, they are also conspicuously contrasting characters and players, partly as a result of their different backgrounds. Common for both of them, though, is their symbolic value in the contexts of their social and national backgrounds.
The influence of injuries on team performance in football has only been scarcely investigated.
To study the association between injury rates and team performance in the domestic league play, and in ...European cups, in male professional football.
24 football teams from nine European countries were followed prospectively for 11 seasons (2001-2012), including 155 team-seasons. Individual training and match exposure and time-loss injuries were registered. To analyse the effect of injury rates on performance, a Generalised Estimating Equation was used to fit a linear regression on team-level data. Each team's season injury rate and performance were evaluated using its own preceding season data for comparison in the analyses.
7792 injuries were reported during 1 026 104 exposure hours. The total injury incidence was 7.7 injuries/1000 h, injury burden 130 injury days lost/1000 h and player match availability 86%. Lower injury burden (p=0.011) and higher match availability (p=0.031) were associated with higher final league ranking. Similarly, lower injury incidence (p=0.035), lower injury burden (p<0.001) and higher match availability (p<0.001) were associated with increased points per league match. Finally, lower injury burden (p=0.043) and higher match availability (p=0.048) were associated with an increase in the Union of European Football Association (UEFA) Season Club Coefficient, reflecting success in the UEFA Champions League or Europa League.
Injuries had a significant influence on performance in the league play and in European cups in male professional football. The findings stress the importance of injury prevention to increase a team's chances of success.
The aim of the study compared effects of intermittent and continuous small-sided games (SSGs) on physiological and technical activities in soccer players. Totally 16 male amateur soccer players (Mean ...age: 22.37±1.69 years, height: 170.89±5.96 cm and body mass: 67.37±7.47 kg) were recruited as participants. Subjects were separated in 4 groups of 4 players according to the Yo-Yo test results and their coaches' comments. Four-a-side SSGs were used in a pitch size of 26 m x 34 m and 2 different small-sided games were used in this study. Intermittent SSG (ISSG) included a series of 3 bouts of 6 min duration with 3 min recovery between sets. Continuous SSG (CSSG) was a bout of 18 min duration with no recovery. Heart rate (HR), the rating of perceived exertion (RPE), and blood lactate concentration (LA) were measured as physical parameters and shoot on target, total pass, accurate pass, inaccurate pass, interception, dribbling, tackle, and possessing the ball were counted by Mathball Match Analyses System. A repeated measures ANOVA method, paired and unpaired tests were used to analyses data. The results of this study suggest that SSGs might cause increases of HR, RPE, and LA and that intermittent and continuous SSGs might not bring about an alteration on HR, RPE and LA.
Durante la competición, los jugadores de fútbol deben realizar esfuerzos tanto físicos como mentales de manera simultánea. Esta situación de doble tarea perjudica el rendimiento en habilidades que ...requieren precisión solo en aquellos deportistas que no tienen automatizada la habilidad. Sin embargo, ha existido poco control sobre la naturaleza y magnitud de la carga mental que experimentan los deportistas durante las acciones de juego, y en qué medida dicha carga perjudica el rendimiento deportivo. Para avanzar en este conocimiento, se ha diseñado un estudio intrasujeto contrabalanceado con medidas repetidas post-condición sobre dos condiciones, una tarea física y coordinativa específica de fútbol, y una doble tarea en la que se mantenía la tarea principal, mientras que la secundaria tenía requerimientos de control cognitivo. Participaron veintiocho futbolistas semiprofesionales masculinos edad media = 20.07 años (±0.23). La presencia de carga física simultánea a la carga mental tuvo un efecto negativo en la precisión. A su vez, los estados emocionales suscitados en la doble tarea predecían el rendimiento en la tarea motora. Obligar al jugador a tener que usar sus recursos atencionales en la tarea mental, parece no permitir un uso adecuado de la información disponible necesaria para un ajuste de la acción de manera eficiente.
Sistemas tácticos y resultados de competición del Mundial de Fútbol Asociación de Rusia 2018Tactical systems and match results from FIFA Worldcup Rusia 2018Julio Cesar Guedea Delgado, Raúl Josué ...Nájera Longoria, Oscar Núñez Enríquez, Ramón Candía Luján, Gabriel Gastélum CuadrasUniversidad Autónoma de Chihuahua (México) Resumen. Los sistemas tácticos dentro del fútbol soccer son elementales tanto a la ofensiva como a la defensiva. El presente estudio consiste en el analizar los sistemas tácticos y resultados de juego de Mundial de Rusia 2018. Se analizaron los 64 partidos, cuyos datos se extrajeron de la Web oficial de la Federación Internacional de Fútbol Asociación (FIFA, www.fifa.com) y registros que se obtuvieron del programa de Sky SPORTS® del canal 1535, los datos se confirmaron mediante el Sky SPORTS® que ofrece una toma táctica aérea en el canal 1536. Los resultados más sobresalientes son el sistema más utilizado el 1-4-2-3-1, donde los dos equipos del 1ro Francia y 2do lugar Croacia lo utilizaron con mayor frecuencia, así mismo el 1-3-5-2 y 1-3-4-3 que son más ofensivos, en los equipos del 3ro lugar Bélgica y 4to lugar Inglaterra. Estos sistemas en ocasiones a la defensiva cambian, dependiendo del rival y las circunstancias, así como la táctica del entrenador. Hoy en día, los sistemas de juego y las metodologías de entrenamiento marcan una pauta específica para los entrenadores, buscando futbolistas que dominen los aspectos técnico-tácticos, que entiendan el sistema y la filosofía de juego que plantea el entrenador y que defiendan y ataquen con la misma intensidad independientemente de la posición que asuman.
The Football Association of England has become a multi-billion pound industry. But how did English football become not only the defining sport of the nation but also one of the most successful sports ...in the world? With The Leaguers, football historian Matthew Taylor tells the story of the early days of professional football in England, revealing the distant origins of today’s game. Making extensive use of archival materials from football clubs, unions, and associations, Taylor presents a compelling picture of football teams and players in the early days of the twentieth century, tracing the development of the system of professional teams from the hundreds of town, club, and school teams that dotted the countryside. The top tier of those teams comprised the Football League that, by the 1920s, was synonymous with the very idea of professional football in the minds of fans and sportswriters alike. The Leaguers illuminates the role played by the Football League—and by successful clubs in the League such as Arsenal and Aston Villa’as the rules, standards, and structure of the modern game were being codified. Taylor also considers the careers and influences of early players, including such well-known names as Billy Meredith, “Dixie” Dean, and Alex James. As football’s popularity grew and sports media proliferated, players found themselves becoming national stars, their portraits on cigarette cards bought by fans throughout England. The first full-length history of the early days of the Football League, The Leaguers will be essential reading for football fans who want to know how their favorite sport grew from modest origins to the worldwide phenomenon that is English football today.
A long-term study providing rare insights into the precarious career and ordinary working culture of professional footballers. Away from the celebrity-obsessed media gaze, the work of a professional ...footballer is rarely glamorous and for most players a career in football is insecure and short-lived.
A former professional, Martin Roderick's familiarity with the world of football is the foundation for this privileged research into a world that is typically closed to the public gaze and ignored by media reportage and academic research which prefers to focus on a small, unrepresentative group of elite players. Key themes explored within the text include:
the culture of work in professional football
the changing identity, orientation and expectations of players during their careers
the fragile and uncertain nature of professional sport careers
the performance and dramatic aspects of a career under public scrutiny
the role of relationships with managers, owners, support staff and partners
players' responses to the insecurities inherent in professional football such as injury, ageing, performance and transfer.
The text deals with a wide range of issues of interest to sports students and academics, particularly those with a focus on the sociology of sport but also including sport development, sport management and coaching studies. The text will also be of interest to researchers in the fields of careers, industrial relations and the sociology of work.
Tomando como base la teoría de las necesidades psicológicas básicas el objetivo del presente trabajo consiste en poner a prueba un modelo en el que se analice la secuencia: percepción del estilo ...controlador del entrenador – frustración de las necesidades psicológicas básicas – malestar de los jugadores. 433 jóvenes futbolistas varones (Medad = 13.58 ± 0.56) respondieron a las variables de interés. Los resultados del modelo de ecuaciones estructurales mostraron que la percepción del estilo controlador predecía positivamente la frustración de las necesidades psicológicas básicas de los futbolistas, lo que a su vez predecía positivamente su burnout, sus afectos negativos y sus síntomas de malestar físico y psicológico. Se encontraron efectos indirectos significativos del estilo interpersonal controlador del entrenador sobre los indicadores de malestar a través de la frustración de las necesidades psicológicas básicas. Los resultados nos obligan a reflexionar sobre las consecuencias adversas que tienen los ambientes controladores creados por las figuras de autoridad en los jóvenes futbolistas.
