Perceived self-efficacy by Under-10 tennis players when scaling the equipment and play area

The modification of child-sports aims to develop an optimal learning environment that facilitates the emergence of desirable psychological outcomes (e.g., self-efficacy). The aim of the study was to assess the effect of reducing net height and court size on self-efficacy and shot-efficacy of U-10 tennis players in a real-game context. Twenty U-10 tennis players (M = 9.46, SD = 0.66 years of age; M = 3.65, SD = 1.53 years of tennis experience) played two round-robin tournaments one week apart in the same order and schedule. The first tournament was played under the International Tennis Federation’s Tennis 10s regulation at green stage (GT). Afterwards, the modified tournament (MT) was played with the same regulation GT, however, net height (0.91 m–0.80 m) and court size (23.77 m × 8.23 m–18.00 m × 8.23 m) were reduced. Results accomplished using Bayesian and Frequentist inferences showed an increase in players’ self-efficacy when serving in MT than GT (BF₁₀ = 4.796; δ = −0.576; and p = .011). This is increase may be due to a reduction in their serving faults in MT (BF₁₀ = 6.169; δ = −0.591; and p = .010). Therefore, reducing net height and court size enhances the serve performance and self-efficacy and thus promotes positive tennis experiences.     

How many creatives are enough? Exploring how manipulating the number of creative players in the opposing team impacts footballers' performance during small-sided games

This study explored how varying the number of creative opponents affects youth players' performance during football small-sided games (SSGs). Initially, 60 players from 3 different age groups with n = 20 in each (under-9, U9; under-11, U11; and under-13, U13) were tested during SSGs to rank them according to their creative potential. Based on these rankings, four players shown to possess with a medium creative potential were assigned to the intermediate team for each age group. This team competed against a team on which players with high creative potential were progressively included (from one to finally all four players, 1C to 4C) during a 4-a-side plus goalkeeper SSG. The results showed that U9 players increased the individual space explored when facing more creative opponents (p = .012), while the U11 (p = .026) and U13 (p < .001) only increased when facing 2C and 3C. Playing against more creative opponents induced more variability in the distance to own (p = .046) and the opponent team's centroid (p = .046) in the U9, regularity in the U11 (team centroid, p < .001; opponents' centroid, p = .001) and lower regularity in the U13 (team centroid, p = .013 opponents' centroid, p = .009). These distinct movement patterns seemed to reflect the differences in players' perceptual and motor skills. A higher creative score was found against 1C (vs 2C and 4C, p = .006) and 3C (vs 4C, p = .006) in the U9. The results from the effect sizes indicated higher values on the players' attempts, fluency and versatility when facing 1C to 3C, whereas a clear decrease was observed against 4C for all age groups. Hence, moderate and high demanding scenarios prompt the emergence of new behaviours while extremely high demanding scenarios (i.e. 4C) seem to constrain all the creativity components. Overall, adding creative players mostly impacts the team's collective behaviour rather than the players' creativity-related skills.     

From childhood to senior professional football: A multi-level approach to elite youth football players’ engagement in football-specific activities

ObjectivesThe main aim of this study was to identify the development of engagement in football-specific activities of elite youth association football (soccer) players who have made the transition to senior professional status or not.DesignComparative research design.MethodData were collected from all elite youth players (N = 745) within the age-range of 14–21 years from all Norwegian Premier League clubs, using a retrospective questionnaire. A within elite-group comparison of players who had obtained a senior professional contract or not was conducted by using multi-level modeling (n = 491).ResultsThe results showed that although the professional players reported to have accumulated more overall practice hours than non-professionals from ages 6 to 19 years, none of these differences were significant. The professional players reported to have accumulated significantly more hours in play and coach-led practice at the youngest age categories. No significant differences were identified at older age categories or for other types of football-specific practice at any age.ConclusionsDifferences in performance attainment may be due to variation in the amount and types of football practice at the earliest years of participation, but may also be related to other factors than the number of hours spent in certain football-specific activities. We argue that implementation of multi-level modeling represents an important progression within practice history research, and is necessary to account for the actual individual’s development over time in addition to identify how different variables may affect the developmental process.     

Applying a relational lens to ethnographic inquiry: Storied insight into the inner workings of multicultural teams in men's elite football

ObjectiveTo examine the impact of transnational migration on the functioning of multicultural teams in men's elite football and to explore the cultural transition experiences of transnational players from the relational perspective of receiving football environments.Designand Method: This 26-month ethnographic study adopted a researcher-practitioner approach to investigate two elite European football clubs during the course of two complete seasons. Over 80 male participants from 18 different countries were involved in the approximately 1200 h of field observation (e.g., practices, games, closed-door meetings, etc.) and 50 h of transcribed interviews. Detailed field notes and interview data were thematically analyzed, followed by a narrative analysis of structure and form. Finally, the genre of ethnographic creative non-fiction was employed to present the findings.FindingsBy applying a relational lens to the study of cultural transitions, this investigation illuminates the centrality of relations in the daily functioning of multicultural teams embedded in transnational networks and spaces. The complex interactional dynamic between transnational players and members of the receiving environment as well as the structural constraints shaping footballing (sub)cultures and behaviours highlight the salience of restrained agency as a collective phenomenon in elite men's football. Moreover, the study explores the hows of cultural transition by engaging with temporality and proposing a complementary perspective that extends current understandings in the narration of cultural transition experiences.ConclusionsThe findings carry applied utility that can benefit stakeholders and practitioners working with culturally diverse teams in the deployment of culturally informed club management strategy, educational tools, and interventions.     

Perceived inclusion in youth soccer teams: The role of societal status and perceived motivational goal climate

ObjectivesOur aim was to investigate the link between youth soccer players' perceptions of the coach-initiated motivational goal climate within their team and their perceptions of inclusion as a function of societal status. Societal status refers to one's national background which numerically forms the majority or a minority in a particular society.Design and methodsSurvey data was collected among 245 male youth soccer players (M = 12.9 years, SD = 1.60), who all played in culturally diverse teams in the Netherlands. The societal status of 94 players (38.4%) was majority, and 151 players (61.6%) were classified as minority. To test our main hypothesis, perceived inclusion as the dependent variable was hierarchically regressed on coach-initiated mastery goal climate perceptions, performance goal climate perceptions, societal status, and their interactions.ResultsOverall, mastery goal perceptions and performance goal perceptions of intra-team competition were positively and negatively related, respectively, to perceived team inclusion. As hypothesized, only among players with a societal minority status, perceptions of inclusion were higher when mastery goal climate perceptions were higher and performance goal climate perceptions were lower.Discussion and conclusionOur findings suggest that a coach-initiated mastery-oriented team climate may enhance an inclusive soccer environment in culturally and nationally diverse teams. For societal minority players, intra-team competition should be de-emphasized by the coach in order to strengthen the experience of inclusion.     

Toward an Understanding of Players’ Perceptions of Talent Development Environments in UK Female Football

This study explored UK female football players' perceptions of their talent development environments using the Talent Development Environment Questionnaire. Participants were 137 UK-based female football players (M_age = 16.06, SD = 1.90) from Football Association Girls' Centres of Excellence and Football Association Women's Super League Development Squads. Players had most positive perceptions of long-term development focus and support network, whereas the least positive perceptions were of communication and understanding the athlete. Sport psychologists could offer significant support in (a) planning for football-specific development and career progression, (b) communication with key social agents, and (c) holistic player development and well-being.     

Exploration of the moderator effect of cultural diversity on team performance across 45 professional football leagues: An ecological dynamics perspective on cross-cultural research

ObjectiveTo investigate the moderating effect of cultural diversity on team performance in professional football worldwide through the lens of ecological dynamics and cross-cultural psychology.Designand Method: Based a sample of 23,186 matches played by 728 teams across 45 leagues during the 2020/21 season, two sets of moderated regression analyses were conducted to examine the effect on sporting results of the interaction between teams’ cultural diversity, their dominant playing style and market value. In addition to bivariate correlations, a total of 16 ordinary least squares (OLS) regression models were designed to test 5 hypotheses. A new theoretical model, the Integrative Categorization-Intentionality Model (ICIM), was proposed to explain four key findings.FindingsCDI’s role as a statistically significant cross-cultural moderator was confirmed in relation to all three styles of play: possession-based (ß = −0.08, p < 0.05), constructive attacking (ß = −0.30, p < 0.01), and defensive (ß = 0.28, p < 0.05), the respective models explaining 35.6%, 34% and 35% of the variance. Results showed that cultural heterogeneity contributes to goal scoring in teams reliant on the first two styles, whilst defensively-oriented teams were more likely to improve performance with increasing cultural homogeneity. Moreover, the positive effect of cultural heterogeneity on sporting outcomes was more likely in less affluent teams. Finally, empirical evidence revealed a link between enhanced performance and a higher proportion of domestic defensive players in defensively oriented teams (ß = −0.11, p < 0.05), and, similarly, between a higher proportion of foreign offensive players in offensively-oriented teams (ß = −0.27, p < 0.01).ConclusionsThe study has practical implications for scouting/recruitment of players when strategizing on team cultural and functional composition, as well as for coaches in terms of designing suitable training practices gauged to match and develop multicultural teams’ diverse skill set, or more generally, in relation to managing multicultural teams.     

Psychological talent predictors in early adolescence and their empirical relationship with current and future performance in soccer

ObjectivesThis study examined the relationship of talented soccer players' psychological characteristics with current and future performance.DesignBoth a cross-sectional and a prospective design were used.MethodThe sample consisted of 2677 U12 players in the German talent development program. Self-report questionnaires captured psychological dispositions and skills that were assigned to the areas of motivation, volition, self-referential cognition, and emotion. Current performance was operationalized by a motor score representing speed abilities and technical skills as well as by coaches' subjective ratings (A = highly promotion-worthy, B = promotion-worthy, C = partly promotion-worthy). The level of future performance was assessed by examining whether individuals were selected for professional clubs' youth academies in U16.ResultsThis study revealed that only self-referential cognitions had a significant and relevant association with the motor score (0.10 ≤ r ≤ 0.37). The players in the subjectively rated categories significantly differed in 10 of 17 psychological scales (0.01 ≤ η² ≤ 0.03). In most of the scales, A-players showed more positively connoted values compared to B- and C-players. Logistic regressions demonstrated that 10 of 17 characteristics explained a significant proportion of players' future success. Players with high dispositions in these characteristics had a greater chance of achieving a higher performance level compared to players with low dispositions (1.61 ≤ OR ≤ 2.65).ConclusionsExpanding on previous research, this study enabled comparisons between a wide range of psychological characteristics with regard to their relevance for soccer performance, leading to conclusions for talent identification and development.     

The decision to adopt a formal athlete leadership group: Qualitative insights from professional football coaches

ObjectivesAthlete Leadership Groups (ALGs) are increasingly being employed in professional football teams and whilst there is a growing body of quantitative research focussed on athlete leadership in other contexts, qualitative studies at the professional level are scant. The purpose of this study is to explore coaches' adoption of formal ALGs in professional football teams and what influences their decisions about the degree to which players are given leadership responsibilities and roles.DesignQualitative- Inductive.Method16 head coaches from 16 professional football teams, across four leagues (Super Rugby n = 4, National Rugby League n = 5, A League n = 3 and Australian Football League n = 4), participated in semi-structured interviews investigating why coaches are increasingly using ALGs in this environment and what influences the extent to which these ALGs are empowered.ResultsAn inductive thematic analysis indicated coaches' initial decisions to adopt an ALG model were influenced by a range of perceived benefits (team management, team functioning and performance) underpinned by personal factors (past experience, coaching philosophy, interpersonal style and understanding of social influence) and their appraisal of situational considerations (readiness, expectations and commitment), which influenced their ALG implementation decisions (how and to what extent players were empowered and leadership responsibilities delegated).ConclusionsOverall, the coaches' decision to use ALGs in the professional football environment was influenced by a belief that player ownership and autonomy, coupled with the influence of peer leadership underpins performance benefits on and off-field and plays a key role in team culture. However, findings suggest that coaches contemplating adopting an ALG model should take an individually tailored approach. For this approach to be effective, coaches consider and address a range of situational factors, and ensure the leadership model adopted reflects their personal beliefs and the capacity and context of the team.     

Collective fit increases team performances: extending regulatory fit from individuals to dyadic teams

People experience “regulatory fit” when they pursue a goal in a manner that suits their chronic regulatory orientation. This regulatory fit impacts performance positively. The present research extends performance gains due to fit from individuals to dyadic team performance. Study 1 manipulated team fit of 32 table football participants (i.e., promotion vs. prevention orientation and offense vs. defense positions). Team fit significantly predicted team success in an experimental tournament beyond team skill level. Study 2 replicated this result with data from a real‐life tournament including 66 highly experienced competitors. These findings broaden the concept of regulatory fit from individual to dyadic teams, and suggest collective fit as a possible important predictor for team success.     

Doing it for the team: Soccer coaches' identity leadership predicts players' effort,turnover intentions,and performance

ObjectivesThe present research investigates how coaches' identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches' identity leadership would be associated with players' perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches' identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players' strength of team identification.DesignWe conducted a cross-sectional study of male soccer players in Germany.MethodThe final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches' identity leadership, team identification, team effort, turnover intentions, and individual/team performance.ResultsAnalysis revealed a positive relationship between coaches' identity leadership and team effort, as well as individual and team performance. Moreover, coaches' identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.ConclusionsThese findings support claims that coaches' identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead.     

Conceptualizing bullying in adult professional football: A phenomenological exploration

ObjectivesThe aim of this study was to gain an in-depth insight into male professional footballers' perception of the concept of bullying and to explore the essences of this behavior within this context.Design and MethodSemi-structured interviews were conducted with 18 adult male professional football players in the UK. Data were analyzed in accordance with the principles of Interpretative Phenomenological Analysis.ResultsParticipants highlighted that key themes within Olewus' (1993) seminal definition of bullying are relevant to professional football such as repetition, power, abuse and harm doing. Notably, there were variations in footballers' views of the constituents of these themes which were explained by divergent perceptions of how the football context shaped these components of bullying. It was evident however, that certain common elements of the football environment, such as its inherent masculinity, identity conforming nature and authoritarianism helped to contextualize the players' conceptualizations of bullying.ConclusionsWhile some of the identified themes mirrored classic definitions of bullying, this concept was articulated in an individually nuanced, context dependent fashion. These findings advance bullying literature by demonstrating how professional football shapes perceptions of this concept, while highlighting the importance of contextually tailored intervention program to address bullying.     

Retrospective and concurrent perspectives of the transition into senior professional female football within the United Kingdom

In the United Kingdom (UK), professional female football has grown exponentially in recent years, including with the advent of the Women's Super League. Given this growth, the present study aimed to (a) to explore the junior-to-senior transition in the UK female football players (i.e., perceived demands, barriers, resources, and coping strategies); (b) to analyze how changes in the UK female football context (i.e., increased professionalization) influenced players' perception of the transition. Six professional female soccer players from two groups took part in the study; senior athlete (N = 3) and transitional athletes (N = 3). To acquire a holistic understanding, semi-structured interviews were conducted with all athletes. Results highlighted transitional athletes appeared to have a different JST experience compared to the senior group, with the difference in experience attributed to the increased professionalization of female football. In particular, demands associated with being a dual career athlete and greater difficulty balancing the competing demands. As a result, transitional athletes also engaged in more coping strategies. This study provides valuable findings in relation to the JST in professional female football and the context of the increasing professionalization of female football in the UK.     

How perceiving additional targets modifies teams’ tactical behavior during football small-sided games

This study aimed to measure how the change on targets information modifies teams’ tactical behavior during football small-sided games. 20 male senior professional players divided in 4 teams of 5 players participated in the study. Each team played two small-sided games, one with 2 official targets with goalkeeper and one with 6 small targets. Positional data of each player were recorded using a 15 Hz portable GPS. The distance between the centers of gravity (CG) of both team, the stretch index and the relative stretch index were measured and differences accessed via standardized differences, coefficient intervals and meta-analysis procedures. A moderate increase on the distance between the CG of each team and a small decrease on the stretch index and on the relative stretch index from 2 targets to the 6 targets games was observed. It was also identified that pitch location affected the interaction between teams. When the game was played in lateral corridors or defensive sectors, the differences between game conditions increased. Emphasizing the information for attacking team to shoot at goal, by manipulating the number of targets constrained tactical behavior of teams. The amplification of specific information on small-sided games can help coaches to promote players and teams’ emergent adapted behaviors.     

A Critique of Howard's Argument for Innate Limits in Chess Performance or Why We Need an Account Based On Acquired Skill and Deliberate Practice

In this issue Howard reported that the effect of chess study is surprisingly small among elite chess players, who continue playing more games in international chess tournaments. In contrast, we show that individual differences in chess study are the likely causes of both higher chess ratings and more chess games played in international tournaments, which is often very costly and includes airfare, hotel, and tournament registration fees. The low correlation between his estimates of study time and chess rating is shown to be a consequence of his methodology of relying on a couple of questions in an internet survey rather than the standard methodology in expert performance research involving a 30‐minute interview tracing yearly engagement in many different practice activities.

Professional handball coaches management of players' situated understanding during official games

ObjectivesThis study, based on the team cognition approach, investigated the information content expressed by coaches when helping players build or update their understanding of the unfolding game. The focus was on how this content fits into the usual task-work/teamwork and procedural/declarative taxonomies.DesignThe data were collected through the audio and video recording of the communications and behaviors of three professional head coaches throughout a total of 15 games. We used deductive content analysis, crossing information contents related to task-work or teamwork with information contents related to declarative or procedural knowledge across the five game periods (first and second half of the first and second half-time, break-time period), and the three score differentials between the teams (favorable, balanced, and unfavorable).MethodWe first performed a multivariate analysis of variance (MANOVA) using a 5 (Game Periods) × 3 (Score Difference) factorial design. Follow-up ANOVAs with repeated-measures were performed to identify the variables contributing to the multivariate effect. We then performed a repeated-measures analysis of variance for information contents related to declarative and procedural knowledge in occurrences of task-work and teamwork categories.ResultsThe results showed that the coaches expressed information related more often to players' procedural knowledge than to their declarative knowledge. We discovered two main effects (game periods and score differences) in coaches' information contents delivered to players. Information related to procedural knowledge was not addressed to the team as a whole, but to certain players.ConclusionsThis suggests that an information flow was more distributed than shared.     

Cognitive representation of auditory space in blind football experts

ObjectivesWe compared the mental representation of sound directions in blind football players, blind non-athletes and sighted individuals.DesignStanding blindfolded in the middle of a circle with 16 loudspeakers, participants judged whether the directions of two subsequently presented sounds were similar or not.MethodStructure dimensional analysis (SDA) was applied to reveal mean cluster solutions for the groups.ResultsHierarchical cluster analysis via SDA resulted in distinct representation structures of sound directions. The blind football players' mean cluster solution consisted of pairs of neighboring directions. The blind non-athletes also clustered the directions in pairs, but included non-adjacent directions. In the sighted participants' structure, frontal directions were clustered pairwise, the absolute back was singled out, and the side regions accounted for more directions.ConclusionsOur results suggest that the mental representation of egocentric auditory space is influenced by sight and by the level of expertise in auditory-based orientation and navigation.     

From reasonable preferences,via argumentation,to logic

This article demonstrates that typical restrictions which are imposed in dialogical logic in order to recover first-order logical consequence from a fragment of natural language argumentation are also forthcoming from preference profiles of boundedly rational players, provided that these players instantiate a specific player type and compute partial strategies. We present two structural rules, which are formulated similarly to closure rules for tableaux proofs that restrict players' strategies to a mapping between games in extensive forms (i.e., game trees) and proof trees. Both rules are motivated from players' preferences and limitations; they can therefore be viewed as being player-self-imposable. First-order logical consequence is thus shown to result from playing a specific type of argumentation game. The alignment of such games with the normative model of the Pragma-dialectical theory of argumentation is positively evaluated. But explicit rules to guarantee that the argumentation game instantiates first-order logical consequence have now become gratuitous, since their normative content arises directly from players' preferences and limitations. A similar naturalization for non-classical logics is discussed.
