A Comparison of Match External Load Demands Across Women's Collegiate Field Sports.

Kuhlman, NM, Jagim, AR, Jones, MT, Feit, MK, and Fields, JB. A comparison of match external load demands across women's collegiate field sports. J Strength Cond Res XX(X): 000-000, 2024-Historically, soccer (SOC), lacrosse (LAX), and field hockey (FH) have been grouped together as "field sports" due to their intermittent nature of match play and similar physiological demands. However, questions have emerged regarding potential variations in demands between sports. The purpose of this study was to compare external match workloads between collegiate women's SOC, LAX, and FH, and examine within-sport positional differences. Athletes (SOC: n = 15; LAX: n = 15; FH: n = 14) wore a global positioning system device during all matches throughout a competitive season. External load metrics included in the analysis were total distance (TD), sprint distance (SD), accelerations (>3 m·s-2), sprint efforts (SE), player load (PL), PL per minute (PL/min), top speed (m·s-1), and distances covered in select speed zones. Soccer performed higher external load volumes (TD, PL) (p ≤ 0.025) but incurred lower intensities (SD, SE, accelerations) (p < 0.001) compared with LAX and FH. Within-sport positional differences were apparent in SOC (p < 0.001-0.018), LAX (p < 0.001-0.045), and FH (p < 0.001-0.004). However, FH exhibited more positional variance in external load metrics compared with SOC or LAX. Field hockey midfielders covered greater volumes (TD, PL) compared with attackers and defenders (p < 0.001), while attackers sustained greater intensities (SD, SE, top speed) compared with midfielders and defenders (p < 0.004). Results indicate that there are significant differences in external workload parameters between sports and across positions. Practitioners should tailor sport-specific and position-specific programs to match demands, and future research should explore the proposed categorizations of LAX as a "fast collision invasion sport," FH as a "fast contact invasion sport," and SOC as a "slow contact invasion sport."

Analysis of Tactical Knowledge for Learning an Alternative Invasion Sport

The study of declarative and procedural knowledge in sport allows us to assess students’ tactical learning processes. The aim of this study was to analyze and compare the level of declarative and procedural knowledge acquired by students according to the pedagogical model and gender, after the application of two intervention programs for an alternative invasion sport, “Rosquilla”. This study involved 136 students distributed into six groups of Primary Education (fifth and sixth year) and Secondary Education (first year). Each group in the same year participated in a different intervention program, one based on the Game-Centered Model and the other on a hybrid model of the Game-Centered Model and the Sports Education Model. A descriptive analysis was carried out to determine the characteristics of the participants. Subsequently, an independent samples Mann–Whitney U-test was applied to compare the level of knowledge between the models and genders in the pre- and post-test periods. A Linear Mixed Model was used to analyze the level of knowledge of students within each group and compare them according to methodology and gender. The results indicate that both programs generated improvements in declarative and procedural knowledge. Therefore, students learn equally regardless of the methodological perspective and gender.

La Validación de dos programas de intervención para el aprendizaje del deporte alternativo “la Rosquilla”

The validation of didactic programs according to a pedagogical model is essential to guarantee the quality of the tasks and their suitability to the methodological approach proposed. The aim of the study was to validate two intervention programmes, corresponding to two didactic units elaborated based on two different methodologies: Game-Centred Model and Hybrid Model of the Game-Centred Model and Sports Education Model, for the learning of an alternative invasion team sport called “the Rosquilla”. Two similar intervention programs were created, which had the same number of sessions, tasks, objectives, contents, and game phases. Nine expert judges participated in the validation process. Content validity was obtained through Aiken's V coefficient and its confidence intervals. Cronbach's α coefficient was used to calculate internal consistency. Eleven and twelve tasks were eliminated from the 60 tasks that made up the intervention programs, Game-Centred Model and Hybrid Model respectively, because they did not exceed the exact critical value (V ≥ .73). The internal consistency achieved by the tasks was excellent (α = .99). Therefore, both intervention programmes are considered valid and reliable for the learning of this alternative invasion sport, “the Rosquilla”. They can be used to compare the effects of both methodologies on students.

An Analysis Comparing Aggression Levels among Female National Volleyball and Netball Athletes in Sri Lanka

Aggression is an important psychological component that cannot be overlooked when it comes to increasing physical performance, particularly in invasion sports. This research was conducted with the intention of determining the extent of the violent behavior exhibited by the female national netball and volleyball players belonging to Sri Lanka. For the purpose of this study, fifteen female volleyball players and ten female netball players from national teams participated. The data was collected through the use of a standardized and systematic questionnaire, and the findings were analyzed through the application of statistical analysis using SPSS. A two-sample t-test and descriptive statistics were utilized in order to conduct the analysis of the data. The study found that the mean aggressiveness scores for the two national teams were 84.06 and 88.9, respectively. These values were based on aggression. According to the findings of the study, the levels of hostility exhibited by the female players on the country's national teams for netball and volleyball did not differ substantially from one another (p-value = 0.577). According to the findings of the study, the levels of aggressiveness exhibited by both teams were satisfactory, and there was no obvious difference in the levels of aggression exhibited by the female national members of Sri Lanka's netball and volleyball teams. An examination of the psychological situations of athletes and the implementation of strategies to optimize player psychology in order to increase athletic performance are both highlighted by the findings, which show the relevance of these two aspects.

Investigating the Emergence of Collective States Within Rugby Sevens Gameplay

ABSTRACT Rugby sevens is a small-sided variant of rugby union characterised by fast-moving, high-intensity gameplay and is an example of a team invasion sport, where players work together to achieve a shared goal of attacking and defending as a cohesive unit. The dynamics of such sports can be viewed as self-organizing systems, where individual players form collective patterns without a centralized mechanism of control. Inspired by the analysis of collective movement in animals, this novel study investigates the emergent patterns of order and disorder in sub-elite female rugby sevens using order parameters (typically used to analyse particle systems) to characterize the team’s collective state during different phases of play. The findings demonstrate that defensive gameplay is more ordered, with more compact formations, compared to attacking play, and there is a correlation between alignment/order in player motion and group speed. The work further suggests that the collective states formed differ between sequences of play with different levels of ground gained by the attacking team. These observations provide a sound justification for player training with a focus on cohesive defensive movements to resist disruptions from opposing attackers, while employing attacking tactics that disrupt the cohesion and order of opposing teams.

Effect of Physical Educators’ Appearance and Sex on Middle School Students’ Learning Outcomes and Perceptions of Teacher Effectiveness

Physical Education (PE) teachers can have a great impact on the future physical activity levels of their students, and later, as adults. Professional appearance of teachers has been shown through previous research to have influence on student learning outcomes and perceptions of teacher effectiveness. This research aimed to build on prior studies to investigate the interaction between formal and informal appearance and gender of physical education teachers with middle school student learning outcomes and teacher perspectives. Four 20-minute videos were produced on the non-traditional invasion sport Tchoukball. The four videos consisted of female informal appearance, female formal appearance, male informal appearance, and male formal appearance. The videos were randomly shown to 433 middle school students located in southeastern United States followed by a post-video content examination and a teacher perception survey. Factoral ANOVAs were performed to identify any significant main effects or interactions on overall content exam, two content areas (skill technique and game strategy), and three teacher perspectives (likability, competence, and teacher as a role model). There was no significant main effect for teacher appearance and student learning outcomes. When considering sex of the teacher, there was a significant main effect for overall examination (F(1, 428) = 9.45, p &lt; .001, η2 = .022, 1-β = .866) and for strategies ((F(1, 428) = 17.22, p &lt; .001, η2 = .039, 1-β = .985), while nothing was found for technique-related questions. On the three teacher perspectives, no significance was found between likability and competence, however there was a main effect on the survey questions about teachers as a role model when taking teacher appearance into consideration ((F(1, 424) = 5.01, p &lt; .001, η2 = .025, 1-β = .612).

The Relationship Between Lower-Body Force-Time Variables and Skating Performance in Female Ice Hockey Players.

Ice hockey is a team invasion sport characterized by repeated high-intensity skating efforts, technical and tactical skill, physical contact, and collisions requiring considerable levels of muscular strength. The purpose of this study was to evaluate the relationships between lower-body vertical force-time metrics and skating qualities in subelite female ice hockey players. A cross-sectional cohort design was employed utilizing 14 athletes (body mass = 66.7 [1.8]kg; height = 171.6 [6.2]cm; age = 21.1 [1.7]y). The relationships between metrics of lower-body strength collected from a drop jump, squat jump, countermovement jump, loaded countermovement jump, and an isometric squat and 4 skating qualities collected from a linear sprint, repeated sprint test, and a multistage aerobic test were evaluated. The regression models revealed a positive relationship between relative peak force in the isometric squat and skating multistage aerobic test performance (r2 = .388; P = .017) and a positive relationship between repeated-sprint ability and eccentric mean force during the loaded countermovement jump (r2 = .595; P = .001). No significant relationships were observed between strength metrics and skating acceleration or maximal velocity. These data suggest that skating ability is most affected by relative isometric strength in female ice hockey players. It is recommended that practitioners focus training on tasks that improve relative force output. It is also recommended that isometric relative peak force be used as a monitoring metric for this cohort.

The Influence of Team Invasion Sports’ Participation in the Phase Angle of Youth Athletes

Team invasion sports are characterized as ball games, played by two opponents, aiming to score points or goals. The aim intended to verify which team invasion sport presents a greater probability to obtain a higher phase angle (PhA) value, considering the age, time of practice, vertical jump tests and handgrip strength of young athletes. A total of 248 young athletes were evaluated. After performing the correlations between the PhA and categorical variables (sport and sex) and covariables (age, time of practice- t, squat jump- SJ, countermovement jump- CMJ, and handgrip strength left or right- HGSl or HGSr), we developed an equation from a logistic regression model, aiming to better interpret the probability to obtain a higher PhA. Our findings showed a significant correlation (p&lt; 0.05) ranging from weak to moderate between the PhA and age (r=0.268), t (r =0.206), SJ (r=0.330), CMJ (r= 0.277), HGSr (r=0.537), and HGSl (r=0.523). Considering the median value of the PhA (7.7o) as a cut-off point, youth soccer players were the most likely to have 2.2 more chances to reach a higher PhA, followed by Futsal (2.13), and Rugby (2.01) players. Considering our equation, we suggested that higher PhA values predisposed the Soccer, Futsal and Rugby players to express greater jumping capacity or handgrip tests. Considering the advantage of using PhA as a marker of a healthy body composition profile, the magnitude of these probabilities to reach higher values of strength performance in young athletes may depend on the sport practiced and their exposure to specific training.

Merging Athletic Development With Skill Acquisition: Developing Agility Using an Ecological Dynamics Approach

ABSTRACT Agility has commonly been regarded as a physical quality, and strength and conditioning practitioners have typically used a closed environment approach for developing agility. This closed environment approach involves the decoupling of perception and action, where actions are trained in isolation from perception. Previous studies have shown, however, that when perception or action is trained in isolation, behavior changes. Therefore, agility is complex and multifactorial in nature. Through ecological dynamics, specifically the principle of representative learning design, practitioners should design training tasks that align more closely with the demands of competition. Representative learning design ensures that perception and action remain coupled to promote greater transfer of performance from training to competition. Another key principle for agility task design is coadaptation, and this can be operationalized through manipulation of opposing players. With these 2 key principles, we offer examples of agility tasks in 3 team invasion sports including soccer, rugby union, and Australian rules football.

Structural Relationship between Psychological Needs and Sport Adherence for Students Participating in Physical Education Class

The satisfaction of basic psychological needs leads students to engage in a sport modality on their own initiative. In the Spanish public educational system, mixed and heterogeneous, the gender and sport experience of students influence the teaching and motivation of invasion sports. This study investigated whether students’ gender and sport experience, and model influence the psychological variables (basic psychological needs and sport adherence) when teaching school soccer and basketball. Furthermore, correlations were calculated between these psychological variables. The study involved 165 fifth and sixth grade students (Mage, 11.27 ± 0.68 years old) from several Spanish state schools in the same autonomous community. A non-random convenience sample was used. The needs for autonomy, perceived competence and social relationships were measured using the Basic Psychological Needs in Physical Exercise Scale. Sport adherence was measured using the Measure of Intentionality to be Physically Active. A Confirmatory Factor Analysis, Cronbach’s Alpha, Average Variance Extracted and Composite Reliability were used to analyze the psychometric properties of the scales. Descriptive and inferential analyses were obtained after performing a Mixed Linear Model and a Bonferroni Post Hoc. There were significant differences in the autonomy need according to the students’ gender (boys &gt; girls). In addition, boys who learned with the TGA model scored significantly higher than girls on this need. Attending to sport adherence, there were significant differences in favor of experienced students. Likewise, a regression analysis (structural equation model) revealed that the autonomy need showed low association with sport adherence. Higher perceived competence (β = 0.52) and social relationships (β = 0.36) were associated with greater adherence to sport (R2 = 0.65). Teachers’ Knowledge and proper managing basic psychological needs will have educational, social and health benefits, as it will increase the likelihood of physical activity in and out of school.

"Getting on the same page" enhancing team performance with shared mental models-case studies of evidence informed practice in elite sport.

Within high performing, team invasion sports, collective decision making and coordination between teammates are essential characteristics. There is a wealth of evidence supportive of shared mental models as being an important construct to underpin team coordination. Yet, to this point, there is limited research considering the coaches' voices in the application of shared mental models in high performance sport, nor the challenges coaches face throughout the process. Given these limitations, we provide two case studies of evidence informed practice which privilege the voice of coaches who work in elite rugby union. In doing so, we aim to offer a deeper insight regarding the development, implementation, and continued use of shared mental models to enhance performance. Through these first-person case studies, we present the development of two shared mental models and the processes taken, challenges faced, and coaching methods used to underpin them. The case studies are then discussed with implications for coaches' practice supporting the development of their players' collective decision making.

Discovery and Characterisation of Forward Line Formations at Centre Bounces in the Australian Football League.

The extent of player formation usage and the characteristics of player arrangements are not well understood in Australian football, unlike other team-based invasion sports. Using player location data from all centre bounces in the 2021 Australian Football League season; this study described the spatial characteristics and roles of players in the forward line. Summary metrics indicated that teams differed in how spread out their forward players were (deviation away from the goal-to-goal axis and convex hull area) but were similar with regard to the centroid of player locations. Cluster analysis, along with visual inspection of player densities, clearly showed the presence of different repeated structures or formations used by teams. Teams also differed in their choice of player role combinations in forward lines at centre bounces. New terminology was proposed to describe the characteristics of forward line formations used in professional Australian Football.

Predicting the unpredictable: analysing the entropy and spatial distribution of ball movement patterns in field hockey.

Analysing the ball movement patterns of team invasion sports provides practical insight into successful strategies by identifying how and where to move the ball to create goal scoring opportunities. The aim of this study was to analyse the entropy and spatial distribution of ball movement patterns in international field hockey teams. A notational analysis system was developed in SportsCode to analyse 131 matches (n = 57 men, n = 74 women) from the 2019 Pro League tournament. The start and end location of each ball movement and the outcome of each play was recorded. Calculated variables included game possession (%), entropy, possession per zone (%) and progression rates. Decision trees identified that higher circle possession and direct movements to goal from deep attack, and lower build attack and build defence entropy, were the strategies most likely to lead to goal shots. However, teams should be unpredictable when the opposition are organised to maintain possession and unbalance the defence. Match context only had small effects on ball movement strategies highlighting there is more than one way to be successful. Executing strategies that exploit these factors should lead to greater attacking opportunities and success. Analysing the dynamic, complexity of international hockey allows coaches to prepare specific strategies for individual teams.

Coaching player decision making in rugby union: exploring coaches espoused theories and theories in use as an indicator of effective coaching practice

ABSTRACT Introduction: Researchers exploring how coaches can best support the development of their players decision making within team invasion sports have often been conducted from a cognitive or ecological approach, which differ in their views regarding the presence and absence of memory representations. This difference has, in turn, resulted in practical implications that are theoretically different, but not pedagogically different. Research has categorised such approaches to coaching decision making into intentional decision making training or incidental decision making training that offer different suggestions for how coaching methods may be used within their practice. Sometimes, these categories of training have been offered as the way coaches should operate over the careful selection of coaching methods given their intentions for impact. Instead, within this study we aim to explore the pragmatic nature of coaching practice, rather than adherence only to theoretical principles or beliefs. Materials and Methods: In this study five English Regional Academy Rugby Union Coaches participated in a semi-structured interview, three categorised systematic observations of their coaching practice and a self-confrontation interview to explore; (i) the espoused theories coaches believe they use in practice; (ii) the theories in use within their coaching practice and; (iii) the alignment and misalignment between their espoused theories and theories in use during their coaching practice. Results & Discussion: Our findings demonstrate that coaches employed a balance and blend of intentional and incidental coaching methods concurrently. Coaches proposed the use of non-linear pedagogy and the manipulation of constraints to promote learning activities which captured the representative nature of the competitive decision making environment. Yet also promoted the role and importance of shared mental models, tactical frameworks, off field video analysis and deliberate if–then rules of thumb when supporting the development of their players decision making. Thematic analysis extracted from interview data regarding coaches espoused theories, alongside the coaches theories in use, captured through categorised frequencies of coach behaviours and learning activities through systematic observations, present clear misalignments between proposed coaching methods and those used in practice. Misalignments were apparent for learning activities, where coaches espoused the need for representative practice but used more single-phase and huddle based scenarios, and coach behaviours, where coaches espoused the importance of setting problems for their participants through divergent questioning, yet used more instructional behaviours and convergent questions leading players toward a shared mental model of collective decision making behaviour. From our findings, we offer practical implications to coaches which suggest that when supporting player decision making, coaches should consider using their judgment to select the appropriate evidence-informed coaching method given their wider intentions for impact in the session and the context in which they operate. Furthermore, we offer a suggestion to coaches and researchers where we encourage the exploration of the chain and gap between what coaches they think they do, and what they actually do in practice as a means for critical reflection.

Classifying ball trajectories in invasion sports using dynamic time warping: A basketball case study.

Comparison and classification of ball trajectories can provide insight to support coaches and players in analysing their plays or opposition plays. This is challenging due to the innate variability and uncertainty of ball trajectories in space and time. We propose a framework based on Dynamic Time Warping (DTW) to cluster, compare and characterise trajectories in relation to play outcomes. Seventy-two international women's basketball games were analysed, where features such as ball trajectory, possession time and possession outcome were recorded. DTW was used to quantify the alignment-adjusted distance between three dimensional (two spatial, one temporal) trajectories. This distance, along with final location for the play (usually the shot), was then used to cluster trajectories. These clusters supported the conventional wisdom of higher scoring rates for fast breaks, but also identified other contextual factors affecting scoring rate, including bias towards one side of the court. In addition, some high scoring rate clusters were associated with greater mean change in the direction of ball movement, supporting the notion of entropy affecting effectiveness. Coaches and other end users could use such a framework to help make better use of their time by honing in on groups of effective or problematic plays for manual video analysis, for both their team and when scouting opponent teams and suggests new predictors for machine learning to analyse and predict trajectory-based sports.

Determinant Factors of Achievement Motivation in School Physical Education.

Today, it is important for physical education teachers to know students’ motivation profiles for learning. Therefore, this study aimed to analyze achievement motivation according to four variables: students’ sex, the taught sport modality, students’ experience and teaching methodology. Likewise, the effects of students’ sex and experience on the methodologies applied were analyzed. A total of 108 primary education students (10.95 ± 0.48 years), 54 boys and 54 girls, from three state schools participated in the study. The students answered the Achievement Motivation in Physical Education test (Spanish version) after participating in soccer and basketball programs based on different methodologies. Each class-group received a different educational program (soccer or basketball). The differences between the categories of the variables analyzed were calculated for each dimension of the motivational test through the Mann–Whitney U and Kruskal–Wallis H tests. The effects of students’ sex and experience on the teaching methodologies applied were analyzed using the univariate General Linear Model test. In soccer and basketball, boys perceived being more motor competent (U = 732.00; p < 0.05; r = 0.43) than girls. In addition, experienced students in both sports perceived being more motor competent (U = 695.50; p < 0.05; r = 0.27) than inexperienced students. In turn, they indicated feeling less failure anxiety and stress (U = 780.00; p < 0.05; r = 0.22). All of the students who played soccer reported more commitment (learning dedication) (U = 1051.50; p < 0.05; r = 0.20) and perceived motor competence (U = 972.00; p < 0.05; r = 0.24) than students who played basketball. Considering the effects of students’ sex and experience on the methodologies (perceived motor competence dimension), there were significant differences (F = 7.68; p < 0.05; ηp2 = 0.07) in favor of experienced boys who played soccer and basketball using the Tactical Games Approach methodology. Soccer was practiced more in school and out of school. This made students feel greater commitment (learning dedication) and perceived motor competence towards this invasion sport in physical education. In addition, it was shown that teachers should take into account students’ sex and experience because they are two factors that influence the teaching of sports and achievement motivation.

Study of three intervention programs for the teaching of basketball at school ages.

The design of learning tasks in invasion sports is linked to teaching-learning methodologies. The quantitative objective of the study was to analyze the differences and similarities of three intervention programs based on different methodologies, Tactical Games Approach (TGA), Direct Instruction (DI) and Service Teacher's Basketball Unit (STBU) for teaching of school basketball, 148 tasks were analyzed. The qualitative objective was to analyze the decisions made by the teacher during the planning. The pedagogical variables and external training load (eTL) registered in the Comprehensive Training Task Analysis System (SIATE) were analyzed. The intervention programs were compared using the Chi-Square, Kruskal-wallis H statistical tests and the corrected standardized residuals (RTC). Likewise, the association strength of the variables was calculated using Cramer's V coefficients and Epsilon Square. The results indicated similarities between the DI program and the STBU. The TGA teaching program got the highest mean quantification of eTL and eTL × time. The teacher in the service phase uses characteristics of the Teacher Center Approach (TCA) approach in the design of his didactic unit and does not apply his previous ideas in the elaboration of it.

Capture, analyse, visualise: An exemplar of performance analysis in practice in field hockey.

The goal of performance analysis is to capture the multitude of factors that affect sports strategy, and present them in an informative, interpretable, and accessible format. The aim of this study was to outline a performance analysis process in field hockey that captures, analyses and visualises strategy in layers of detail culminating in the creation of an RStudio Shiny application. Computerised notational analysis systems were developed to capture in-game events and ball tracking data of 74 matches from the Women’s Pro League 2019. Game styles were developed using k-means cluster analysis to reduce detailed in-game events into practical profiles to identify the attack types, game actions and tempo of a team’s strategy. Ball movement profiles were developed to identify the predictability (entropy) and direction (progression rates) of ball movements, and consequent distribution of possession in different attacking zones. The Shiny application, an interactive web-platform, links the information from simple game profiles with detailed game variables to understand each teams’ holistic game plan, how they are different, and how to exploit these differences. The process outlined can be applied to any team invasion sport to understand, develop and communicate successful strategies under different match situations.

The Application of Machine Learning Techniques for Predicting Match Results in Team Sport: A Review

&#x0D; &#x0D; &#x0D; Predicting the results of matches in sport is a challenging and interesting task. In this paper, we review a selection of studies from 1996 to 2019 that used machine learning for predicting match results in team sport. Considering both invasion sports and striking/fielding sports, we discuss commonly applied machine learning algorithms, as well as common approaches related to data and evaluation. Our study considers accuracies that have been achieved across different sports, and explores whether evidence exists to support the notion that outcomes of some sports may be inherently more difficult to predict. We also uncover common themes of future research directions and propose recommendations for future researchers. Although there remains a lack of benchmark datasets (apart from in soccer), and the differences between sports, datasets and features makes between-study comparisons difficult, as we discuss, it is possible to evaluate accuracy performance in other ways. Artificial Neural Networks were commonly applied in early studies, however, our findings suggest that a range of models should instead be compared. Selecting and engineering an appropriate feature set appears to be more important than having a large number of instances. For feature selection, we see potential for greater inter-disciplinary collaboration between sport performance analysis, a sub-discipline of sport science, and machine learning.&#x0D; &#x0D; &#x0D;

Does anticipation of penalty kicks in soccer transfer across similar and dissimilar sports?

The aim of the present study was to examine whether anticipation skill associated with penalty-kick scenarios is sport-specific, or whether it transfers between sports that have similar elements. A shortened participation history questionnaire was used to identify 97 soccer players, 47 invasion sport players (e.g., rugby), and 72 other sport players (e.g., swimming), as well as skill level (hours of engagement/competition level). These participants completed a video-based temporal occlusion anticipation test that required them to select the destination of the ball across a series of soccer penalty scenarios. Results indicated that the skilled soccer players were more accurate than the skilled and less-skilled invasion sport players and skilled and less-skilled other sport players. Skilled soccer players were also more accurate than the less-skilled soccer players, with less-skilled soccer players exhibiting similar accuracy to both the skilled and less-skilled invasion sport and other sport players indicating that processes associated with anticipation of penalty kicks may be specific to their sport.
