Comparative Analysis of the Physical, Tactical, Emotional, and Mood Characteristics of Under-13 Soccer Players by Performance Level

Background and Objectives: Soccer is a sport characterized by various unpredictable situations in which physical abilities are associated with athletic performance. There are several capabilities that young soccer players must develop to adapt to the needs of the competition. This study analyzes the physical characteristics, tactical knowledge, emotional intelligence, and mood states of youth soccer players at different competitive levels. Materials and Methods: The sample consisted of 36 male soccer players with an average age of 12.65 ± 0.48 years, weight of 44.92 ± 7.49 kg, and height of 157.2 ± 0.08 cm. A cross-sectional correlational study design was selected. Inferential analysis was conducted via the RV coefficient to assess relationships between groups. Two-sample tests (Student’s t test or the Mann–Whitney U test) were used to assess the distribution of the samples. Standardized mean differences (i.e., Cohen’s d) were calculated as effect sizes. Results: For the yo-yo intermittent endurance test level 1, the Premier category showed higher speed (p = 0.01, d = 0.40) and superior estimated VO2max (p = 0.01, d = −0.91). The statistically significant variables included the hamstring strength exercise of the hamstrings for the angle of rupture (p = 0.04, d = −0.04, d = −0.72), the COD-Timer 5-0-5 for contact time—5-0-5 (ms) (p = 0.04, d = 0.69) and 10 m—5-0-5 (s) (p = 0.02, d = 0.79), tactical knowledge of in-game performance (p = 0.01, d = −1.19), support level (p = 0.01, d = −1.27), decision-making ability (p = 0.01, d = 0.59), melancholy (p = 0.01, d = 0.59), confusion (p = 0.01, d = 0.56), and emotional intelligence (p = 0.04, d = 0.77). The Premier category presented slightly higher averages than did category A. In the assessment of running-based anaerobic sprint test power (p < 0.05, d = 0.83) and mood states (p < 0.05, d = 0.59), players in category A presented higher results. Conclusions: The performance capacity of youth soccer players encompasses a multidimensional complexity that includes physical, tactical, emotional, and psychological aspects, which vary among players of the same age.

Changing Horses in Midstream: Modern Pentathlon After the 2024 Olympic Games.

The decision of the Union Internationale de Pentathlon Moderne to replace horse riding with Obstacle after the 2024 Olympic Games challenges training, testing, and recovery management in Modern Pentathlon. This commentary discusses physiological, technical, and tactical effects of rule changes in the 5 disciplines with a specific focus on the new discipline Obstacle. Modern Pentathlon requires athletes to develop specific endurance capacities relying on both the aerobic and anaerobic systems while simultaneously increasing lower- and upper-body strength capabilities. In addition, movements must be repeatedly executed in an explosive and precise manner. Running and swimming must be fast but economical. Swapping from horse riding to Obstacle will prioritize the explosive strength of the upper extremities and core while keeping high levels of endurance and precision in swimming, fencing, and shooting. Moreover, condensing the Modern Pentathlon competition to a 90-minute television-friendly format enables more competitions in the future. Athletes and coaches will thus also need to develop and maintain effective individual peri-exercise routines (before, during, and after the competition) to successfully meet the resulting tactical and physical challenges of the new format. This commentary aims to stimulate the discussion on the effect of the Union Internationale de Pentathlon Moderne's decisions to replace riding with the new Obstacle discipline and implement a more television-friendly format with a focus on physiological, technical, and tactical aspects.

Pressing, pressure and re-aggressing as tactical movement of anterior cruciate ligament injuries in women's soccer.

A better understanding of anterior cruciate ligament (ACL) injury mechanisms in female soccer can guide better research on both prevention programs and late-stage rehabilitation for the return-to-sport process. This narrative review investigates the technical and tactical game situations in female soccer linked to ACL injury mechanisms. Through a literature search, we reviewed scientific literature to identify soccer-specific technical movements and tactical patterns that increase the risk of ACL injuries in female players. Articles were retrieved through Web of Science, SPORTDiscus, ScienceDirect, PubMed, and PubMed Central. Inclusion criteria were: 1) studies on ACL injury mechanisms in women's soccer; 2) studies examining soccer techniques/tactics to identify non-contact injury mechanisms. Gray literature was included to supplement limited indexed data, aiming to stay within author guidelines. Female athletes experience a 2-8 times higher risk of ACL injury than males, with 70% of these injuries being non-contact. Common scenarios leading to these injuries involve ball possession/non-possession phases, tactical actions (pressing, pressure, re-aggression), and technical movements (cutting, changing direction). Tactical aspects, particularly pressing and re-aggression, are key contributors to ACL injury risk regardless of ball possession. In female soccer, ACL injuries are related to non-contact injury mechanisms during technical and tactical situations. The knowledge and study of these situational patterns of play, such as pressing, re-aggression, pressure, and cutting maneuvers, are essential to target prevention strategies and return-to-sport processes objectively.

Проблема футбольного інтелекту у сучасних дослідженнях

Speed, dynamism, high physical and mental loads characterize modern soccer. In this regard, the player's intelligence plays an important role during the game, because it: affects the form of tactical behavior; allows to make effective decisions in stressful situations; increases the player's ability to understand and establish links between game episodes and solve problematic game episodes using available tactical information. Therefore, the study of theoretical, tactical and psychological aspects of the development of intellectual abilities of a player is important for obtaining high results in this sport. The aim of the study is to analyze theoretical research on the peculiarities and development of intellectual abilities of soccer players. Research methods: theoretical analysis and generalization of scientific and methodological literature. Research results. As a result of the conducted analysis of literary sources it was determined that soccer intelligence is a way of thinking that allows a player to solve problem situations using knowledge, experience, skills and natural data, which are best suited for a particular game situation. Player's intelligence is a complex multilevel structure that is the result of player's adaptation to the conditions of the game space, constitutes a special form of tactical behavior of the player, is the result of purposeful tactical training of the player as a set of elementary processes of information processing and a system of cognitive processes. Conclusions. In soccer, the intellectual component is an integral part of both the game itself and the training process. Coaches are interested in its improvement and effective use because soccer intelligence is a way of thinking that allows a player to successfully solve problem situations using knowledge, experience, skills, and natural data that are best suited for a particular game situation.

Factors influencing the relationship between coaches and athletes with disabilities: a systematic review.

The relationship between coaches and athletes with disabilities is critical for enhancing athletes' performance and psychosocial well-being. This study aims to provide evidence-based recommendations for coaches, sports organizations, and policymakers dedicated to supporting athletes with disabilities. A comprehensive analysis of existing literature was conducted. Five databases were searched, including PubMed, Web of Science, SPORTDiscus, Google Scholar, and China National Knowledge Infrastructure. A total of 22 studies were included for thematic analysis. This systematic review identifies key factors influencing the coach-athlete relationship in disabled sports. These factors are categorized into three main domains: professional, interpersonal, and intrapersonal. In the professional domain, effective coaching requires sport-specific skills and adaptive techniques tailored to the unique needs of athletes with disabilities. Coaches must understand the technical and tactical aspects of each parasport and adapt training plans to optimize performance and foster independence. The interpersonal domain emphasizes communication strategies and team-building practices. Effective communication involves understanding athletes' needs and adapting approaches to maximize strengths. Building rapport, managing conflict, and fostering a supportive team environment are crucial for maintaining a positive coach-athlete relationship. The intrapersonal domain highlights the importance of self-reflection and continuous learning. Coaches who engage in self-reflection and professional development better understand their behaviors and biases, enabling them to tailor coaching strategies to the specific needs of athletes with disabilities. Continuous learning is essential for remaining responsive to the evolving needs of these athletes. This review underscores the importance of a holistic approach that integrates professional expertise, interpersonal skills, and intrapersonal awareness. By addressing these factors, it provides a foundation for developing more effective coaching strategies and supports for athletes with disabilities, ultimately enhancing their performance and well-being. Future research should explore cultural differences, the specific coaching needs of athletes with intellectual disabilities, and the impact of policies and structural barriers on the coach-athlete relationship in disabled sports.

Antecedents, Characteristics, and Dynamics of IPV in the Israeli Jewish Ultra-Orthodox Community: A Cultural Exploration

Abstract Purpose This qualitative study explored Intimate Partner Violence (IPV) in the Israeli Jewish Ultra-Orthodox (JUO) community to better understand the cultural and religious risk factors and features underlying IPV in this under-researched sector. Method Semi-structured interviews implementing the Clinical Ethnographic Narrative Interviews approach were conducted with 15 JUO women currently living with or separated/divorced from their abusive partners who were victims of IPV. The interviews were analyzed using the Interpretive Phenomenological approach. Results Two key themes emerged from the analysis. The first theme involves the normalization and exacerbation of violence due to specific religious and societal norms that perpetuate silence and stigma. Factors such as early marriage, religious beliefs about the sanctity of marriage, disadvantaged childhood experiences, and distorted religious justifications contributed to the victims’ vulnerability and hindered their ability to seek help. The second theme is related to the specific features of the abuse. It covers a range of tactics employed by husbands, including financial oppression, social isolation, physical violence, and manipulation during pregnancy, all based on and justified by distorted religious concepts. Conclusions Though aspects of intergenerational abuse and control tactics to aggravate violence are common universal strategies in IPV, the findings here underscore the interplay between religious practices and societal expectations within the JUO community that contribute to the perpetration and perpetuation of IPV. These findings contribute to a better understanding of IPV in religious and traditional contexts and highlight the importance of tailoring interventions to address the needs of specific collectivistic and religious-based societies.

Examining tactical sprint actions and distribution among playing positions attending to match status in soccer: Implications for specific training.

The study aimed to analyze the tactical sprint actions performed by Spanish professional soccer players, considering their playing positions and the match status at the time of each action. Thirty-two Spanish male professional soccer players from a LaLiga Spanish Second Division (LaLiga SmarthBank) team participated in this study. Actions above 85% of the players' maximum velocity during 42 official matches were collected by an optical tracking system ChyronHego® and were synchronized using Mediacoach software (LaLiga, Madrid, Spain). Then, actios were analyzed trough an observation instrument designed to assess the type of tactical action performed by players. Central defenders (CD) and wide defenders (WD) were mainly involved in recovery runs. Central midfielders (CM) also frequently performed recovery runs and pressing actions. Wide midfielders (WM) were often engaged in runs in behind/penetrate actions, while forwards (F) had a diverse range of sprint actions, including pressing, runs in behind/penetrate, and breaking into the box. It was observed that F performed fewer chase actions than expected. On the other hand, CD, WD, and CM engaged in a greater number of recovery run actions than expected. CD also performed more close down/interception actions than expected, while CM, WM, and F performed fewer close down/interception actions than expected. When their team was losing, WM performed more recovery run actions than expected. CM made more runs with the ball when their team was winning CD showed a higher frequency of breaks into the box when their team was winning. These findings provide valuable information regarding the tactical aspects of sprinting in soccer, facilitating the design of specific training tasks that not only address the physical demands associated with each playing position but also considering the tactical context in which sprints occur.

Tactical Situations and Playing Styles as Key Performance Indicators in Soccer.

The game of soccer is complex and unpredictable, demanding multifaceted strategies for success. Performance analysis has evolved, focusing on key performance indicators (KPIs) to determine the factors that most significantly influence a team's success or failure during matches. Traditional performance analysis methods have emphasized quantifiable data like physical exertion and basic play events but often neglected the subtler tactical dimensions that could significantly impact game outcomes. This study aimed to fill the gap in the current literature by creating a comprehensive framework that incorporates tactical situations as KPIs. The objective was to examine whether specific playing styles adopted by teams in various tactical situations and phases of the game could predict the outcome of matches. A dataset comprising all First Division Championship matches from 11 different European countries for the 2021-2022 season was analyzed. Variables representing tactical situations were correlated with match outcomes using a Generalized Estimating Equation framework. The model was specified with a binomial distribution and a logit link function. Statistical significance was determined using Wald χ2 tests with a significance level set at p < 0.05. The study's findings revealed that possession style, counterattacking during offensive transitions, and a balanced aggressive defensive strategy significantly increase a team's chances of victory. It also showed that successful teams tend to focus on central attacks, minimize crossing, and execute strategic plays that lead to final attempts on goal with minimal ball possession. The above findings demonstrate that adopting certain tactical approaches significantly influences soccer match outcomes, highlighting the importance of considering tactical aspects as KPIs.

Performance of soccer players under acute physical fatigue: An approach based on cognitive, tactical and physical aspects

This study aimed to verify whether peripheral perception, tactical behaviour, and physical performance are influenced by acute physical fatigue in soccer players. The study included 24 trained soccer players (18.6 ± 1.5 years) from two Brazilian clubs. The TSAFT90 test was used to induce acute physical fatigue. The results showed that physical fatigue did not affect peripheral perception (p = 0.360). Regarding tactical behaviour, improved efficiency was observed for the principles of offensive coverage (p = 0.029), width and length with the ball (p = 0.044), and concentration (p = 0.008). On the other hand, a reduction was observed in the number of tactical actions of offensive coverage (p = 0.020) and recovery balance (p = 0.042). Also, improved accuracy in the principles of defensive balance (p = 0.009), recovery balance (p = 0.021) and defensive unity (p = 0.003) occurred under physical fatigue. A reduction in the physical performance outcomes total distance covered (p < 0.001), average speed (p < 0.001), sprints (p = 0.029), number of accelerations (p = 0.008) and decelerations (p = 0.008) were also detected. The internal (p < 0.01) and external (p < 0.01) workload was higher under physical fatigue. Overall, acute physical fatigue did not influence peripheral perception. However, physical performance was reduced under fatigue, the perceived effort increased, and tactical behaviours were affected by decreasing tactical actions performed near the ball, increasing errors in defensive movements in the lateral corridors and the last defensive line, and improving offensive tactical actions performance.

Analysis of external load and internal load in AirBadminton

The aim of this study was to compare internal load and external load between AirBadminton and traditional indoor badminton. The research was conducted with 8 badminton players from the Alicante Technification Centre, including both men and women. The study was carried out based on the recommendations and guidelines of the International Badminton Federation. The procedure included competitions in both 1vs1 and 2vs2 formats, first on sand and then on hard court. Various variables related to players' internal and external load were analysed, using devices such as WIMU PRO for external load and Polar H7 transmitters for internal load. Data analysis was performed using statistical tests such as T-Student and Wilcoxon. Results showed significant differences between indoor badminton and AirBadminton in terms of internal and external load. In the 1vs1 format, indoor badminton was found to be more demanding, with higher intensity efforts, greater distance covered, and higher heart rate compared to AirBadminton. Similar results were observed in the 2vs2 format, confirming that indoor badminton involves greater effort. AirBadminton may be a healthier and more accessible alternative, suitable for different age groups, as it is less explosive and lighter in terms of internal and external load. Future research should focus on technical, tactical, and full-match duration aspects of this new modality.

The psychological characteristics of football players under the age of 17 in Indonesia

Football is the most popular sport in Indonesia and involves thousands of players and millions of spectators. As the sport continues to grow, it demands an accelerated development of players and adjustments to their needs. However, the Indonesian Football Association (PSSI) has created a curriculum that only focuses on the physical, tactical, and technical aspects, ignoring the psychological aspect. This study aimed to investigate the role of psychology in the development of football players in Indonesia, focusing on the weaknesses of the current curriculum. The study was concentrated on the development and psychological characteristics that soccer players under 17 years of age require to maintain their performance into adulthood. The study used a grounded theory approach and semi-structured open questions in data collection. The sample included youth player-coaches with a minimum of 5 years of experience, as well as football players under the age of 17. These players typically begin practicing football at the age of 6 and continue until they reach 17 years old in Indonesia. The results of this study can be a reference for the PSSI and football coaches in Indonesia to create a comprehensive training program that includes physical, technical, tactical, and psychological aspects, enabling them to develop successful football players in the future.
