The Functional Movement Screen (FMS) has been applied to identify predisposed players, mainly in professional sports, and their injury risk. Empirical evidence on the FMS in amateur soccer is scant. Furthermore, the composite FMS score contains upper, lower, and core-related body items, which might be related differently in soccer-specific injury incidences. The aim of this study was twofold: to investigate the relationship between the composite FMS score and the injury incidence of amateur soccer players and to analyze the contribution of single FMS test items to the injury state. In all, 83 amateur male soccer players (23?±?4 years old) were evaluated using the FMS prior to the preparation period of the 2016/2017 season. Injuries (lower extremities, non-contact, time loss) were continuously documented throughout the first competition period. The composite FMS score differed significantly (p?=?0.017) between injured (15.1?±?2.5) and non-injured (16.5?±?2) players. A twofold increase in the risk of injury was found for a composite FMS score of 14 or less. Significant correlations between single test items with a score?≤?2 and injured players were found for the trunk stability push-up exercise (χ2?=?17.4, df?=?1, p?<?0.001, φ?=?0.5) and the rotary stability exercise (χ2?=?6.7, df?=?1, p?=?0.009, φ?=?0.3). The composite FMS score seems to be an indicator of injury risk in amateur soccer with injured players having lower core stability and lower core strength. 相似文献

ABSTRACT The aim of the current study was to objectively identify position-specific key performance indicators in professional football that predict out-field players league status. The sample consisted of 966 out-field players who completed the full 90 minutes in a match during the 2008/09 or 2009/10 season in the Football League Championship. Players were assigned to one of three categories (0, 1 and 2) based on where they completed most of their match time in the following season, and then split based on five playing positions. 340 performance, biographical and esteem variables were analysed using a Stepwise Artificial Neural Network approach. The models correctly predicted between 72.7% and 100% of test cases (Mean prediction of models = 85.9%), the test error ranged from 1.0% to 9.8% (Mean test error of models = 6.3%). Variables related to passing, shooting, regaining possession and international appearances were key factors in the predictive models. This is highly significant as objective position-specific predictors of players league status have not previously been published. The method could be used to aid the identification and comparison of transfer targets as part of the due diligence process in professional football. 相似文献

In today’s leading football training centres, state-of-the-art performance diagnostic systems such as the “Footbonaut” allow controlled and standardized assessments of physical and mental components of agility, e.g. speed of action and ball control, that are considered to be decisive for talent identification and development. However, effects of induced physical and mental strain on performing football-specific practice patterns remain to be elucidated, particularly in youth players, and, thus, characterize the purpose of this study. 33 randomly assigned competitive football players (U14 to U16) performed a standardized Footbonaut practice pattern (i.e. 20 balls randomly drawn at 50?km/h each), prior to and immediately after either mentally demanding tasks (MDT; n?=?11; continuous Vienna Test System’s Stroop task and determination test), physically demanding tasks (PDT; n?=?11; consisted of 4?×?4?min of football-specific high-intensity intervals with 3?min of active recovery in between) or a control condition (CON; n?=?11). Continuous heart rates (HR) as well as self-perceptions of fatigue were assessed. Main findings revealed performances for speed of action (p?=?0.44; f?=?0.01) and ball control (p?=?0.15; f?=?0.03) that were not modulated in the face of induced physical and mental strain as indicated by increased HR following PDT (p?<?0.001; d?>?0.8), or in the face of increased self-perceptions of fatigue following PDT and MDT (both p?<?0.001; both d?>?0.8) compared to CON. This is in line with a suggested talent factor and previous reports on motivational trade-off aspects in youth players. However, the present study’s short-timed practice patterns make it difficult to reliably compare a measuring sensitivity to complex football-specific movement behavioural and technical proficiencies with respect to mental and physical strain of longer-lasting football games and, thus, need further investigation in favour of improving talent identification and development using the Footbonaut. 相似文献

In recent years unfair competition and match fixing have become an increasing focus of public attention. Uncovered instances of match fixing influence the integrity of football. In the field of professional football there are well-known cases, such as the Calciopoli scandal in Italy and the case of the German referee Robert Hoyzer, where referees were involved in match fixing. However, so far little is known about how often attempts are made to influence referees and their decisions in amateur football in Germany. Data from a large scale survey of referees (n = 4813) showed that approximately 10?% of referees in amateur football have already been approached in an attempt to influence their decisions by offers of money or non-cash benefits. Results of logistic regressions show various correlats of being approached for match fixing by offers of money or non-cash benefits. The probability of being approached increases with the duration of referee activity, the number of games refereed per year, and decreases with age. 相似文献

AbstractAcute infectious diseases are common in athletes and can impair their ability to train and to compete. Furthermore, continuing exercise during infectious diseases may lead to prolongation or aggravation of illness with severe acute or chronic organ manifestations. Therefore, even simple infectious diseases require a sufficient period of convalescence and recovery, during which exercise may be not allowed. Nowadays, especially in professional football with high pressures on players, staff and clubs due to broad public interests as well as financial constraints, the return-to-play decision is of utmost significance. Based on previous suggestions and our own experience within amateur and professional athletes and football players, this article aims to give a short overview on return-to-play decisions after common acute infectious diseases in football players. 相似文献

This review focuses on Gaelic football and scientific reports of the characteristics of its players and the demands of the game. Anthropometric characteristics vary according to positional role, but top players display high muscularity and good all-round fitness at the peak of the competitive season. Match analysis indicates that exercise intensity is roughly equivalent to that for professional soccer. Average heart rates are approximately 160 beats· min-1 during competitive matches, and average oxygen consumption is about 72% of maximum. Metabolic fatigue in active muscles is unlikely. Conventional biomechanical and electromyographic techniques are useful in gaining insight into individual games skills. Inadequate attention has been given to injury prevention and to psychological aspects of the game. Although possessing unique characteristics, Gaelic football has many similarities with other football codes, especially Australian Rules football where the ball is played by both hands and feet and where tackling is permitted. 相似文献

The popularity and profitability of American gridiron football is beyond dispute. Recent polls put football as the overwhelming favorite of people who follow at least one sport and huge revenues are reported at both the professional and the university level. We know, however, that what is the case tells us little about what ought to be the case, and it is to the latter question that this paper is directed. I offer a three-pronged attack on the ethical acceptability of American football, both amateur and professional, based on (1) harm to the players, (2) objectification of the players, and (3) harm to others done by the players, leading to the conclusion that the sport, as currently constituted, is morally unacceptable. 相似文献

Derived from Basic Psychological Needs Theory (BPNT) is the notion that the social environment may promote athletes’ basic psychological needs, which are considered important for positive development and optimal motivational functioning. The present study investigated the predictive value of perceived justice and coach feedback on basic needs satisfaction in the context of youth football. Participants were Norwegian youth football players (N?=?532) participating in a national tournament. During the initial stage of the tournament, players completed the Coaching Feedback Questionnaire, Perceived Justice in Sport Questionnaire and Basic Psychological Needs in Exercise Scale under supervision. Regression analysis showed that perceived justice and positive/instructive coaching feedback positively predicted players’ needs satisfaction, while negative feedback and non-reinforcement/ignoring mistakes were not significant predictors of needs satisfaction. Together, perceptions of justice and coach feedback explained 24% of the variance in athletes’ needs satisfaction. The findings thereby indicate that athletes’ perceptions of fairness and coach feedback are important in understanding youth athletes’ needs satisfaction. 相似文献

Abstract The main purpose of this article was to review a series of studies (n=23) on physical characteristics, physiological attributes, throwing velocity and accuracy, and on-court performances of male handball players – amateur players, experienced players, professional players, and players on the national team. Five main findings emerged from our review: (1) Elite players are heavier and have higher fat-free mass than amateur players. (2) The maximal oxygen uptake of male players is between 50 and 60 ml · kg?1 · min?1. (3) Throwing velocity is higher by as much as 9% in elite male players compared with amateur male players. (4) Heart rates can rise above 160 beats · min?1 in male players during a game. (5) On-court distance covered in a game averaged approximately 4 km and ranged between 2 and 5 km, depending on playing position. Our methodological concerns based on the reviewed studies are: (a) a lack of on-court physiological data; (b) a lack of experimental/manipulative studies; (c) limited data on throwing accuracy; and (d) a lack of longitudinal studies. The practical implications include: (a) strength and power exercises should be emphasized in conditioning programmes, as they are associated with both sprint performance and throwing velocity; (b) speed and agility drills should also be implemented in conditioning programmes; and (c) specificity of training based upon the position of the player is of great importance when planning strength and conditioning programmes. 相似文献

Science and Gaelic football: a review 总被引：1，自引：1，他引：0
This review focuses on Gaelic football and scientific reports of the characteristics of its players and the demands of the game. Anthropometric characteristics vary according to positional role, but top players display high muscularity and good all-round fitness at the peak of the competitive season. Match analysis indicates that exercise intensity is roughly equivalent to that for professional soccer. Average heart rates are approximately 160 beats x min(-1) during competitive matches, and average oxygen consumption is about 72% of maximum. Metabolic fatigue in active muscles is unlikely. Conventional biomechanical and electromyographic techniques are useful in gaining insight into individual games skills. Inadequate attention has been given to injury prevention and to psychological aspects of the game.

The organization of individual sports into leagues has received little attention in research, but its practical relevance has increased. This article aims to elucidate the role of competitive balance and league design elements in a sports league with less spectator demand from a player perspective. The analysis focuses on the reformed German Golf League. Because this league is an amateur league with no payment for players and currently few spectators, a change in perspective is appropriate. The empirical results of the stated preference approach highlight the relevance of perceived competitive balance as well as several league characteristics for the players. The findings thus show that governing bodies of sports leagues should focus on both the development of an optimal league design and soft aspects to deliver attractive and challenging competition from a player’s perspective. 相似文献

This article provides a systematised review of relevant factors influencing youth dropout from organised football. The findings of identified 30 studies concerning dropout behaviour in football indicate the multidimensional influences of intrapersonal, interpersonal and structural factors. Most studies investigate the influence of intrapersonal factors. Accordingly, negatively perceived football competence, lack of motivation, goals and incentives and a lower relative age lead to a higher dropout rate. At the interpersonal level, lack of support from significant others (parents, peers, coach) and a disadvantageous team situations promote withdrawal from organised youth football. A lack of organisational and structural conditions promote dropout too. Based on this review, the following identified research gaps should be addressed in future studies: (1) analysis of individuals’ dropout decision as a selection of available alternatives, (2) referencing to corresponding contextual features of dropout behaviour, (3) the longitudinal perspective at dropout behaviour and (4) the perspective of intervention. Furthermore, some practical implications can be derived for the management of youth members in football clubs: (1) strengthen and develop successive coaching competencies, (2) reflection of own club philosophy against the background of divergent expectations of adolescents, (3) measures to promote identification with the football club and (4) anchoring of orientation regarding to young players as a central objective in the club. 相似文献

This article explores the development of a football club as a means of understanding its late adoption of professionalism and its unusual wartime conduct. Ipswich Town were the only Football League team not to kick a ball for the duration of the Second World War. Arguably, the underlying causes of the club's inactivity in both global conflicts can be found in the patriotic and staunchly amateur ethos that permeated the organisation, resulting in a very late conversion to the professional game in 1936. When the Amateur Football Association (AFA) seceded from the Football Association (FA) in 1907, Ipswich Town sided with the gentlemen amateurs and competed in the socially-exclusive Southern Amateur League until the season before the club adopted professionalism. The unique nature of Ipswich Town's evolution offers an opportunity to explore the decline of this branch of the game in the face of professional football, the protagonists who were caught up in it, and the relationship between football and civic pride. In wartime, the human and social continuities between the professional company and its amateur predecessor arguably proved to be more influential than the ruptures that resulted from a controversial inter-war abandonment of cherished amateur principles. 相似文献

Several talent-screening programs conducted within elementary schools have implemented motor diagnostics to introduce children to groups of sports including both game and specific sports, the latter of which includes gymnastics, skiing, and tennis. However, as in most other sports, the predictive value for soccer regarding such early testing is unclear. This prospective cohort study evaluated the mid-term prognostic validity of general motor tests as well as a soccer-specific score calculated from a test battery. The sample consisted of N?=?2965 U9 age group of children from the Fulda Movement Check (FMC). The FMC is a basic check comprised of two anthropometric parameters and eight general items of the German Motor Test 6–18 by Boes and Schlenker with the addition of a ball throw. The test data were collected from the second grade classes of 2011–2014. The soccer competition performance of those children who chose soccer (n?=?316) up to the end of the season 2016/17 (September 30, 2017) was recorded. This group of U12–U15 players was then assigned individually to four different competition levels. The prognostic validity of the motor tests was determined using analysis of variance, odds ratios, and a discriminant analysis. All diagnostic methods exhibited medium to high prognostic validity over the 2? to 6?year time span from the talent screening and talent orientation period to the later soccer competitions in the early adolescent U12–U15 age groups. The prognostic relevance of the nine general motor tests was confirmed. 相似文献

ABSTRACTOptimizing collective behaviour helps to increase performance in mutual tasks. In team sports settings, the small-sided games (SSG) have been used as key context tools to stress out the players’ awareness about their in-game required behaviours. Research has mostly described these behaviours when confronting teams have the same number of players, disregarding the frequent situations of low and high inequality. This study compared the players’ positioning dynamics when manipulating the number of opponents and teammates during professional and amateur football SSG. The participants played 4v3, 4v5 and 4v7 games, where one team was confronted with low-superiority, low- and high-inferiority situations, and their opponents with low-, medium- and high-cooperation situations. Positional data were used to calculate effective playing space and distances from each player to team centroid, opponent team centroid and nearest opponent. Outcomes suggested that increasing the number of opponents in professional teams resulted in moderate/large decrease in approximate entropy (ApEn) values to both distance to team and opponent team centroid (i.e., the variables present higher regularity/predictability pattern). In low-cooperation game scenarios, the ApEn in amateurs’ tactical variables presented a moderate/large increase. The professional teams presented an increase in the distance to nearest opponent with the increase of the cooperation level. Increasing the number of opponents was effective to overemphasise the need to use local information in the positioning decision-making process from professionals. Conversely, amateur still rely on external informational feedback. Increasing the cooperation promoted more regularity in spatial organisation in amateurs and emphasise their players’ local perceptions. 相似文献
