Do Different Playing Formats and Aerobic Capacity Influence Variances in Psychophysiological Demands and Technical Performance in Small-Sided Games? A Study among Under-17 Male Soccer Players.

This study aimed to: (i) analyze the variations in psychophysiological demands (mean heart rate, meanHR; rate of perceived exertion, RPE) and technical performance (umber of successful and unsuccessful passes, and occurrences of ball loss) between 2v2 and 4v4 small-sided games (SSGs) formats, and (ii) examine the relationships of aerobic capacity measured in Yo-Yo Intermittent Recovery Test (YYIRT) on psychophysiological and technical performance during SSGs. This study used a cross-sectional design with repeated measures, where the same players participated in both 2v2 and 4v4 formats across two training sessions per format. Twenty-four talent/developmental male youth soccer players, aged 16.6 ± 0.5 years. The meanHR, measured through heart rate sensors, the RPE, assessed using the CR6-20 scale, and the number of successful and unsuccessful passes, along with occurrences of ball loss, recorded using an ad hoc observational tool, were evaluated in each repetition. Players during the 2v2 format had significantly greater mean HR (+4.1%; p < 0.001; d = 2.258), RPE (+12.2%; p < 0.001; d = 2.258), successful passes (+22.2%; p = 0.006; d = 0.884), unsuccessful passes (+62.5%; p < 0.001; d = 1.197) and lost balls (+111.1%; p < 0.001; d = 2.085) than 4v4 format. The YYIRT was significantly and largely correlated with unsuccessful passes (r = 0.502; p = 0.012) and lost balls (r = 0.421; p = 0.041) in 2v2 format. In conclusion, this study suggests that engaging in 2v2 activities constitutes a more intense form of practice, significantly enhancing individual participation in technical aspects. Moreover, aerobic capacity may influence the smaller formats of play and how players perform key technical actions. Therefore, coaches must consider this to ensure the necessary performance in such games.

The Effect of Strength and Balance Training on Kinesiophobia, Ankle Instability, Function, and Performance in Elite Adolescent Soccer Players with Functional Ankle Instability: A Prospective Cluster Randomized Controlled Trial.

We aimed to implement strength and balance training for elite adolescent male soccer players with functional ankle instability (FAI) to assess kinesiophobia, ankle instability, ankle function, and performance. This cluster randomized controlled trial comprised 51 elite adolescent male soccer players with FAI recruited from six different teams, divided into strength, balance, and control groups (SG, n = 17; BG, n = 17; and CG, n = 17, respectively). The SG and BG underwent strength and balance training sessions three times per week for 6 weeks. Primary outcomes were the Tampa scale for kinesiophobia-17 (TSK) and Cumberland ankle instability tool (CAIT) scores to assess kinesiophobia and FAI, respectively. Secondary outcomes were ankle strength (four directions), dynamic balance, static balance (ellipse, displacement, velocity), and performance (figure 8 and side-hop tests). A significant interaction effect was observed for both TSK and CAIT post-intervention (both, P < 0.01). In post hoc analyses, the BG had significantly better outcomes in reducing TSK. The SG and BG showed greater improvements in CAIT scores. Regression analysis indicated that CAIT severity correlated significantly with TSK (P = 0.039, R = 0.289). For secondary outcomes, the SG and BG were superior in terms of ankle dorsiflexion/inversion strength, static balance displacement, and figure-8 and side-hop tests (all, P < 0.05). The BG showed significantly better static balance ellipse results (P < 0.05). The 6-week intervention significantly enhanced kinesiophobia management, ankle stability, and performance. Balance training effectively mitigated kinesiophobia and improved balance, compared with strength training alone. Even small variations in CAIT severity can influence kinesiophobia, highlighting the potential benefits of balance training. Integrating balance training into training programs can address both physical and psychological aspects of ankle instability. Research is recommended to explore the longitudinal effects of these interventions and their potential to prevent injury recurrence.

The Impact of Social Media and Socio-Cultural Attitudes toward Body Image on the Risk of Orthorexia among Female Football Players of Different Nationalities.

BACKGROUND/OBJECTIVES: Orthorexia Nervosa (ON) is an emerging behavioral pattern characterized by an obsessive focus on healthy eating. Despite its prevalence, ON lacks formal diagnostic criteria in major classification systems like the DSM-5 and the ICD-10. This study aims to investigate the impact of socio-cultural attitudes towards body image and the role of social media on the risk of ON among female football players from Poland, Turkey, and India. This study hypothesizes that socio-cultural pressures and media usage significantly influence the risk of developing ON, particularly in cultures more exposed to Western beauty ideals. METHODS: The study was conducted from May to August 2024, employing the Computer-Assisted Web Interview method. A total of 142 female football players aged 16-36 from Poland, Turkey, and India participated. Data were collected using a structured questionnaire that included demographic information and health metrics, the Socio-Cultural Attitudes Towards Appearance Questionnaire, and the Duesseldorf Orthorexia Scale. Statistical analyses included an ANOVA, the Kruskal-Wallis test, the chi-square test, and Pearson's correlation coefficient. RESULTS: The study found that nearly half of the participants were at risk of or presented with ON, with the highest prevalence being among Indian athletes. Statistically significant relationships were observed between the risk of ON and factors such as age, dietary exclusions, social media usage, and sources of nutritional information. However, no significant correlation was found between socio-cultural attitudes and the risk of ON, suggesting that other factors may play a more critical role. CONCLUSIONS: While socio-cultural pressures and media use are contributing factors to the risk of ON, psychological factors and individual behaviors appear to be equally, if not more, significant. This study highlights the importance of targeted educational programs and psychological support for young athletes, with a focus on promoting healthy dietary practices and positive body image perceptions across varying cultural contexts. Additionally, the results suggest the need for further research into the specific psychological and behavioral mechanisms underlying ON.

The role of transformational leadership in the associations between coach-athlete relationship and team resilience: A study on elite football players.

This study explores the relationship between the quality of coach-athlete relationships, transformational leadership style, and team resilience in elite football players. The coach-athlete relationship is an essential factor affecting many performance-related properties of athletes, such as mental health, psychological needs, motivation, and resilience. The study examines how the quality of coach-athlete relationships explains the team resilience feature through transformational leadership. The research group includes 210 elite players from the Super League, First League, Second League, and Third Leagues of the Turkish Football Federation (TFF) in the 2020-2021 football season. The study used descriptive and relational models to explore the current state of the dependent and independent variables and examine their relationships. The findings revealed insights into the mediating role of the coach's transformational leadership qualities, highlighting how the quality of coach-athlete relationships impacts team resilience.

Physiological and Psychological Effects of Short-Term Recreational Football in Adults 60.

Recreational football has shown growing evidence that it could be played safely in adults aged 60+ and that it is physically beneficial. Less is known about the psychological aspects, except for the lived experiences of players. The aim of the present study was to analyze both physiological and psychological effects of short-term recreational football. Fifteen participants took part in a six-week training program of recreational football played at a walking pace with two sessions of 1 h and 30 m per week. Physical fitness was assessed before and after the training period and psychological questionnaires were given at the same time. Body mass and body mass index were significantly decreased, but no other significant effects were found on physical fitness. Participants experienced less frustration related to psychological needs (autonomy and competence). Six weeks were too short to observe significant physical improvements while psychological benefits were already experienced. In this short period, psychological aspects seem predominant. These effects may encourage to long-term adhesion. The activity has the potential to keep adults 60+ exercising, which is important for maintaining good global health and seeing physical changes later.

How do referees visually explore? An in-situ examination of the referential head and eye movements of football referees.

The majority of a football referee's time is spent assessing open-play situations, yet little is known about how referees search for information during this uninterrupted play. The aim of the current study was to examine the exploratory gaze behaviour of elite and sub-elite football referees in open-play game situations. Four elite (i.e. national) and eight sub-elite (i.e. regional) referees officiated an in-situ football match while wearing a mobile eye-tracker to assess their gaze behaviour. Both referential head and eye movements (i.e. moving gaze away from and then back to the ball) were measured. Results showed gaze behaviour was characterised overall by more referential head than eye movements (~75 vs 25%), which were of longer duration (~950 vs 460 ms). Moreover, elite referees employed faster referential movements (~640 vs 730 ms), spending less time with their gaze away from the ball (carrier) than the sub-elite referees. Crucially, both the referential head and eye movements were coordinated relative to key events in the match, in this case passes, showing that referees anticipate the passes to ensure that the referential movements did not occur during passes, rather before or after. The results further our understanding of the coordinative gaze behaviours that underpin expertise in officiating.

Football team quality and fans' attachment: investigating the mediating role of emotional satisfaction in changchun yatai football club (CYFC) fans.

BACKGROUND: Football, as a global phenomenon, intertwines team quality and fan attachment. This study, centered on Changchun Yatai Football Club (CYFC) fans, explores how emotional satisfaction acts as a mediator in this intricate relationship, providing nuanced perspectives crucial for understanding and optimizing the dynamics of fan-team connections in football culture. OBJECTIVES: The primary objective of this research is to examine the influence of team quality on emotional satisfaction and fans' attachment. Additionally, it aims to investigate the mediating role of emotional satisfaction in the relationship between team quality and fans' attachment. By achieving these objectives, the study seeks to contribute valuable insights into the dynamics of fan-team relationships in the context of football. METHODOLOGY: The research adopts an applied approach in terms of its purpose, aiming to provide practical implications for football clubs. The data collection method is descriptive, utilizing electronic questionnaires voluntarily completed by 396 fans of CYFC. The research tool comprises three questionnaires: the team quality questionnaire adapted from Zhan et al. (1997), the emotional satisfaction questionnaire developed by Reynold and Bettie (1999), and a researcher-made attachment questionnaire. Structural equation modeling is employed to analyze the gathered data. RESULTS: The results obtained through structural equation modeling reveal a significant impact of team quality on both emotional satisfaction and fans' attachment. Furthermore, a positive and significant relationship is identified between emotional satisfaction and fans' attachment. The study also confirms the positive mediating role of emotional satisfaction in the connection between team quality and fans' attachment. CONCLUSIONS: In conclusion, the research suggests that football clubs can influence fans' attachment by strategically enhancing team quality. This improvement can be achieved through measures such as acquiring high-quality players and stars. Understanding and addressing the mediating role of emotional satisfaction can be a key strategy for clubs looking to strengthen their connection with fans. The findings provide practical insights for football clubs seeking to optimize their strategies for fan engagement and attachment.

English Premier League and English Football League academy managers' experiences of how psychosocial skills and characteristics are identified and developed in youth academy soccer players.

Psychological skills and characteristics (PSCs) are vital for player development, yet there is a lack of agreement on which are important and how they should be identified and developed in academy players, creating barriers to implementation into curricula. The key stakeholder with considerable insight into PSC development is the academy manager (AM). The aims of this study were (a) explore AMs' experiences of PSC identification and development, (b) identify challenges AMs feel affect development of PSCs. Nine AMs (i.e. Category 1; n = 3, Category 2; n = 3 and Category 3; n = 3) comprising an average coaching experience of 20.4 ± 7.4 years and time in the role of 5.2 years ±3.2 years participated in semi-structured interviews. Reflexive thematic analysis generated themes identified ideal PSC outcomes that AMs felt were important. AMs identified current practices within academies alongside challenges: transitions, need to upskill coaches, access to additional support from external partners and National Governing Bodies. There was consensus that PSCs are key drivers of progression and that embedding them into the pathway was critical to facilitating development. Academies should think carefully about design, implementation and evaluation of programmes to support player PSC development for success during and after soccer careers.

Goalkeepers benefit from using deceptive actions in the soccer penalty kick.

Most studies on deception in soccer penalty kicks have focused on the deceptive actions used by penalty takers. However, it is worth noting that deception can also be played out by goalkeepers. To examine the effectiveness of goalkeepers' deceptive actions in professional competition, we analysed 714 penalty kicks taken during matches in the English Premier League and German Bundesliga, spanning the seasons from 2016-2017 to 2019-2020. We scored whether goalkeepers used deception, and if so, what type of deception, the outcome of the penalty and the kicking strategy of the penalty taker. The results showed that goalkeepers used deception in half of the penalty kicks, resulting in significantly less goals compared to penalties without deception. This advantage was similar for the different types of deception, but larger when penalty takers paid attention to goalkeepers. We propose that the deceptive actions by goalkeepers are effective, mainly because it leads the penalty taker to lose focus. The practical implications of these findings are discussed for both goalkeepers and penalty takers.

Understanding enjoyment within the context of the children-to-youth sport transition in Norwegian soccer: A mixed methods study.

Enjoyment has emerged as a critical factor in understanding dropout and participation in the Norwegian youth soccer context (Persson et al., 2020; Solstad et al., 2022). Moreover, the children-to-youth sport transition within this context represents a shift in underlying values and aims (Hjelseth, 2016). The purpose of this mixed methods study was thus to investigate youth soccer players' enjoyment within the children-to-youth sport transition context. The quantitative phase consisted of 214 soccer players (28.2 % girls, Mage = 12.56 years) who completed a questionnaire, and structural equation modeling was used to analyze the data. The quantitative data informed the selection of participants for qualitative interviews in the next phase. A total of 10 soccer players (6 boys and 4 girls) who had reported different levels of enjoyment were interviewed. Coding reliability thematic analysis was applied to analyze the qualitative data. The results indicated that expectation of success and the mastery-approach goal had a positive relationship with enjoyment. The qualitative data further revealed that love for the sport, being with friends, and learning and mastery were sources of enjoyment for the players. A key finding was that players experienced increased seriousness in the transition, which may have a negative impact on their enjoyment. In conclusion, coaches should emphasize players' expectations of success, learning, and intrapersonal mastery, while creating a team culture that values friendship and passion for the sport. These strategies can enhance enjoyment, potentially sustaining youth participation in soccer during the children-to-youth sport transition.

The limits of sportswashing. How the 2022 FIFA World Cup affected attitudes about Qatar.

Non-democratic regimes have increasingly been hosting major sports events to boost their visibility and image abroad, which sparked debates about the potential for "sportswashing". Using the case of the 2022 FIFA World Cup in Qatar we examine how the framing of the tournament influenced opinions about Qatar abroad. Our pre-registered survey experiment with more than 14,000 respondents in eight European countries conducted before the tournament shows that framing it in light of human rights issues in Qatar leads to more negative attitudes towards the host of the World Cup. In contrast, frames emphasizing Qatar's organizational capacity improve respondents' attitudes. The heterogeneity of effects across countries highlights the relevance of the national information environment for the effects of major sports events on public opinion. These findings suggest that critical media coverage could potentially mitigate sportswashing efforts while uncritical coverage can increase the legitimacy of autocracies.

The relationship between young football players' psychological health resources and the psychological quality of their football experiences: A cross-sectional study.

Studies taking a person-centred statistical approach when examining young peoples` psychological experiences in sport is scarce. The main aim of the present study was to examine the relationships between young football players' psychological health resources and the psychological quality of their football-specific experiences. Data for this cross-sectional study was collected as part of the [BLINDED] arm of the larger Promoting Adolescence Physical Activity (PAPA) multi-centre project [1]. The sample consisted of young [BLINDED] male (n = 814), female (n = 576), grassroots football players between the ages of 10 and 15 years (M = 12.5 years, SD = 1.1 years). We performed a latent profile analysis using Mplus 8.4 using a robust maximum likelihood estimator (MLR). Players with the most resourceful psychological health profile experienced more coach social support (mean = 4.38) than did those with a less well-off resourceful profile (mean = 3.79) and those with the least well-off profile (mean = 3.28). Players with the most resourceful profile also felt a stronger sense of unity among their teammates and they enjoyed football more than those least well off (mean = 4.43 vrs. mean = 3.12 and mean = 4.74 vrs 3.50. respectively). Parallel between-profile differences were also found for the players' general health resources including perceived life satisfaction, general health and family affluence as covariates. Findings suggest that variations in young players' psychological health profiles and their general health resources play a role in the quality of their football-specific psychological experiences.

Exploring proportions of spontaneous and goal-directed self-talk - It is not always the one or the other.

The dichotomous classification of self-talk statements into goal-directed as a more controlled type of self-talk and spontaneous as a more uncontrolled type of self-talk might be an oversimplification. To address this issue, two studies were conducted aiming to explore the idea that the distinction between the two self-talk types should rather be proportional and not mutually exclusive. In Study 1, football players took part in a penalty competition and were subsequently asked to state the self-talk they had before and after the penalty. In Study 2, table tennis players took part in two activities (i.e., a precision task and a competitive set) and were subsequently asked to state the self-talk they had before the individual rounds in each activity. In both studies, the players subsequently rated for each self-talk statement the extent to which it was spontaneous and the extent to which it was goal-directed. The majority of self-talk statements were rated to some extent as both spontaneous and goal-directed. For Study 1, paired-sample t-tests showed that before a penalty kick self-talk was more goal-directed than spontaneous and after the penalty kick it was more spontaneous than goal-directed. In the more exploratory Study 2, multilevel regression analyses showed that the two types of self-talk could not predict sports performance. While the results support the usefulness of the distinction between spontaneous and goal-directed self-talk, treating the two types of self-talk as proportional rather than dichotomous might reflect more accurately the mental activity. Key words: dual-process, organic self-talk, self-regulation, System 1, System 2.

Relation of general-perceptual cognitive abilities and sport-specific performance of young competitive soccer players.

In soccer, skill is significantly influenced by motor skills and physical constitution. In addition, perceptual-cognitive abilities are thought to affect sport-specific performance. Nevertheless, there are hardly any studies investigating the relationship of general cognitive abilities with sport-specific performance. Therefore, the aim of this study was to analyze relationships between general perceptual-cognitive abilities and soccer-specific performance in competitive youth sports. Thirty highly talented male youth soccer players aged 12-14 years completed various perceptual-cognitive (selective attention, cognitive flexibility, inhibition, working memory, peripheral perception, and choice response) and sport-specific on-field tests. Cognitive abilities were assessed using a computer-based test system. Soccer-specific performance skills were evaluated by two sport-specific on-field tests. The relation between perceptual-cognitive abilities and soccer-specific performance was examined using a correlation analysis as well as a four-stage regression analysis. Overall, the expression of general perceptual-cognitive abilities was found to have an impact on performance in soccer-specific test situations, particularly cognitive flexibility and selective attention. Our results suggest that general cognitive tests could be an important tool for the evaluation of cognitive abilities in soccer. This study brings together key approaches in expertise research and makes a significant contribution to a better understanding of expertise in soccer.

Acute effects of a vigorous-intensity warm-up on response suppression and decision-making of football referees.

This study investigates the acute effect of physical exercise simulating a standard pre-competitive warm-up on the response suppression and decision-making of football referees. Thirty-four referees (n = 17 - regional level; n = 17 - national level) participated in the study. A Stop-Signal Task (SST) and a decision-making video test were used to evaluate the referees' perceptual-cognitive functions. The findings revealed that the vigorous aerobic exercise acutely impacted basic cognitive functions, as indicated by decreased reaction time and decreased choice accuracy. However, higher-order cognitive functions such as response suppression and decision-making did not exhibit significant changes post-exercise. Based on these results, there is no evidence to suggest that a vigorous-intensity warm-up is likely to favour response suppression and decision-making factors in the initial phases of the game. National referees showed superior response suppression abilities (shorter stop-signal reaction times and lower probability of responding to the stop-signal) than regional referees, indicating that higher-level referees possess enhanced perceptual-cognitive skills, likely influenced by their experience. Further studies are required to determine whether these variables can be acutely improved through physical exercise. In this regard, our results suggest the need for alternative strategies in pre-competitive referee warm-ups if aiming to improve perceptual-cognitive skills in the initial phases of the game.

Can watching the World Cup make you mentally healthier? Positive associations between involvement in physical activities and flourishing were mediated by psychological need satisfaction.

BACKGROUND: The current understanding of the relationship between physical activity involvement and flourishing, as well as the underlying psychological mechanisms, remains limited. Building upon the basic psychological need theory, this study investigates whether and how engaging in physical activities, either as a spectator (e.g., in sports events such as the World Cup) or a participant, explains individual differences in flourishing. METHODS: A total of 1201 Hong Kong-based Chinese adults (Mage = 42.90, SD = 11.40; 54% female) completed an anonymous online survey from the quarter-final to final stages of the 2022 FIFA World Cup in December 2022. RESULTS: Findings showed that spectator (World Cup) involvement and participant involvement were positively correlated. Moreover, both types of involvements were correlated with flourishing. In addition to the hypothesized positive association with relatedness satisfaction, spectator (World Cup) involvement was also demonstrated significant associations with autonomy and competence satisfaction. Path analysis indicated that associations between physical activities and flourishing were partially mediated by the satisfaction of all three basic psychological needs. CONCLUSIONS: This study is the first to apply the basic psychological need theory in the context of physical activity and supports its relevance in understanding individual differences in flourishing. Different stakeholders are encouraged to recognize the benefits of both spectator and participant involvements in physical activities, which may help them develop supportive strategies (e.g., physical activities with parents, sports events for spectators and participants, and funding for media/communities) in mental health promotion.

Exploring the Relationship of Declarative Tactical Knowledge With Participation, Football Competence, and Potentiality in a Professional Club (Real Sociedad).

We compared the declarative tactical knowledge (DTK) of 196 male and female players (16.9 ± 2.4 years) belonging to the academy of a Spanish professional football club with their participation (minutes played), football competence (coaching staff assessment), and future potential (technical direction prediction). The DTK had no correlation with the minutes played (%) by the participants during the 2021-22 season (r = -.162, p = .045). Student's t test for independent samples compared the football competence of the participants with high DTK (n = 74) and low DTK (n = 76), proving a small impact (p = .021, d = 0.39) in favor of the first group. Although the high-DTK group showed a better average of potentiality, the technical direction identified more potential players for the first team in the low-DTK group. In conclusion, no solid evidence was found to justify that participants with higher DTK in each team were those who played more minutes and showed greater football competence and potentiality.

Do negative stereotypes and domain identification moderate novice participants' performance on a soccer-dribbling task ?

The present research aimed to explore whether negative stereotypes and domain identification moderate novice participants' performance on a soccer-dribbling task, using a novel statistical procedure to explore within-subjects moderation effects. Fifty-four women with no soccer experience (Mage = 19.92, SDage = 1.0) were recruited and assigned to a negative stereotype condition or a nullified-stereotype condition and performed a soccer-dribbling task as fast as possible. Using moderation analyses for repeated measures, results showed (i) that inducing a negative stereotype did not moderate participants' performance, and (ii) that domain identification did not moderate participants' performance in a stereotype threat situation. In conclusion, the novice participants performance did not depend on the value of domain identification and the stereotype condition. More research is nonetheless needed to disentangle the question of how and why novice participants can be impacted by a stereotype threat situation.

Dual-Tasks in Soccer: Effects of Players' Experience and Task Condition on Physical Performance.

In this study, we examined whether experience level and various dual motor and cognitive or single tasks influenced young soccer players' physical performance during small-sided games. Participants were 72 players from U-13 (n = 36) and U-17 (n = 36) groups who participated in 3-to-a-side small-sided games under four experimental conditions: control, a secondary motor task, an additional related secondary cognitive task, and an additional secondary non-specific task. We used GPS devices to measure physical performance in terms of distances covered and accelerations at different thresholds. We found no significant interaction effect between player experience and task condition (p = .540), meaning that dual tasks had comparable effects on players of different experience levels. There were significant main effects of both experience level (p < .001) and condition (p < .001) on most physically related variables. Older players outperformed younger ones, particularly in high-intensity actions. While secondary motor tasks decreased physical performance, secondary cognitive tasks, irrespective of specificity, did not impair players' performances. In conclusion, experience level did not influence the players' physical response to dual tasks, and a secondary motor task was more disruptive to physical performance than either of two types of secondary cognitive tasks. Cognitive tasks can be incorporated into soccer training without compromising physical performance.

Effects of a Psychological Intervention Program on Competitive Anxiety and Psychological Profile in Young Soccer Players.

Our aim in the present study was to test the efficacy of a 13-week, 19-session psychological intervention program on young soccer players' competitive anxiety and their sport psychological profiles. Participants were 37 players in the under-15 age category, of which 18 players formed the experimental group (M age = 14.67 years, SD = .48) and 19 players formed the control group (Mage = 14.23 years, SD = .42); this was a quasi-experimental design without random assignment to groups. We had all participants complete the Psychological Inventory of Sport Performance (IPED), the Questionnaire of Psychological Characteristics of Sport Performance (CPRD), and the Competition State Anxiety Inventory-2 (CSAI-2) before and after the intervention. Results indicated positive effects for the intervention group (but not the control group) on stress control and motivation dimensions of the CPRD, cognitive anxiety and self-confidence on the CSAI-2, and self-confidence and attentional control on the IPED. These results suggest that psychological training for athletes contributes to their improved psychological skills, providing them tools to better adapt to the competitive environment.
