Relationship of Selected Kinematic Variables with the Performance of a Goal Kick Techniques in Football Goalkeeper

Introduction: A goal kick is awarded when the whole of the ball passes over the goal line, on the ground or in the air, having last touched a player of the attacking team, and a goal is not scored. The purpose of this study was to find out the relationship of selected angular kinematic variables with the performance of goal kick technique of soccer goalkeepers in Ethiopia's higher premier league. Method: Purposive sampling technique was used for choosing highly skilled goalkeepers. In the present study, a total of seventeen male goalkeepers (18 to 30 years of age) who had participated in the Ethiopian premier league participated. Goal kick technique was divided into three phases, such as the stance phase, the execution phase and the follow-through phase. All goalkeepers were given three trials and the best trial was used for analysis. Each participant performed three goal kicks with maximum strength that were video recorded with a camera (nikon d3200) positioned 9 m away from the place of the kick at the height of 0.95m. The silicon coachpro 7 and kinovea software were used for analyzing the data. The Joint Point Method was used in order to obtain the values of selected angular kinematic variables by developing a stick figure. The height of the Center of Gravity was calculated by segmentation method. The relationship of selected angular & linear kinematic variables with the performance of goal kick soccer goalkeeper was obtained by spearman rank correlation method. Conclusion: During stance phase, hip joint (left and right), ankle joint right, shoulder joint right and elbow joint left, do have a significant relationship with the performance of goal kick in soccer goalkeeper. At the time of execution phase, angular kinematic variables such as ankle joint left, hip joint right, shoulder joint right and elbow joint right do show a significant relationship with the performance of goal kick in soccer goalkeeper. Whereas the elbow joint left and wrist joint left were insignificant relationships. At the time of follow-through phase, ankle joint right, elbow joint left and hip joint were significant.

Searching for the perfect goalkeeping personality. Myth or reality?

Psychological factors such as personality characteristics are influential factors of the goalkeeping performance in football (soccer). Not only for individualized treatment in practice, also from a scientific point of view, profiling goalkeepers is a relevant part of understanding athletes. The aim of this study was to investigate personality traits of goalkeepers of different expertise, age, and sex. Using the Five Factor Model of personality we assessed personality traits of 132 male and female football goalkeepers ranging from youth to senior and low to elite level. A series of analysis investigated differences between the groups focusing on expertise, age, and sex. Significant differences in the personality trait agreeableness between groups of different expertise and sex could be detected. Although a significant difference in neuroticism levels of males and females could be shown. This study was a first step of profiling football goalkeepers of different expertise, age, and sex. The study calls for more replication in this specific field of football and goalkeeping in general to understand the influence of personality characteristics on sport performance.

Sports selection of goalkeepers in modern strategies of the game of football teams

A goalkeeper in a football team is a player of a special playing role. Since ancient times, a simple sporting truth has been defined in football: if a team has a reliable goalkeeper, this is half of the overall success of the team's game. However, it is precisely due to their "professional peculiarity" that goalkeepers for a long time have been partially deprived of due attention in the process of sports selection of players of various roles. At present, certain attempts have been made to introduce into the system of functioning and training of football teams the position of coaches who would be engaged in specialized training and sports training of goalkeepers. This approach mainly applies to highly qualified teams and powerful football academies. Real Holistic Concepts of Specialized Training and Sports Training of Goalkeepers as a System Product of the Process of Sports Selection in the Ukrainian scientific and methodological space are practically absent. Usually, the educational and training process with the participation of goalkeepers is, as a rule, the result of the generalization of their own professional and playing experience of goalkeeper coaches. The significant relevance of the study of competitive activity based on the use of methods of sports selection of goalkeepers in modern football has led to the choice of the topic and the structure of writing and forming the concept of this scientific and practical study.

Investigating the relationship between achievement motive and performance in elite-level football goalkeepers

The goalkeeper position in football is highly specific. Investigating the achievement motive of elite-level goalkeepers might help football coaches in general, goalkeeping coaches, and sports psychologists to gain insight into and knowledge of the approaches needed for enhancing the performance of this unique position within the football team. This study aimed to examine the achievement motive for male goalkeepers playing at the elite level in Denmark (n = 34) and Iceland (n = 20) and to investigate the relationship between the achievement motive, age and performance. In addition to biographical questions, the study employed the Achievement Motives Scale – Sport. The findings from the present study suggest that goalkeepers are characterized by higher hope for success than fear of failure values, like other elite athletes, while younger goalkeepers had significantly higher fear of failure. There were no differences between starting and non-starting goalkeepers, but we found that performance level was associated with fear of failure when controlling for the goalkeeper’s status (starters versus non-starters) and playing country. Finally, goalkeepers playing in Denmark showed lower fear of failure than goalkeepers playing in Iceland. Implications for practice and future research are discussed.

Comparison of force variables and dynamic strength index between age groups in elite young Brazilian football goalkeepers.

The application of muscle force is a determinant of football success as it is inherent to the motor control and sport. The aims of this study are: (1) to describe force variables Isometric Maximal Force (IMF), Concentric Peak Force (CPPF), and Dynamic Strength Index (DSI) in football goalkeepers from different age groups; (2) to compare these variables' behavior between those groups. The sample was formed by 19 youth players (15.97 ± 1.55 years old) from a first-division Brazilian football team. The CPPF and IMF variables were obtained through the Countermovement jump and isometric squat tests, respectively. For data collection, a force plate (Cefise, Brazil) was used with an acquisition frequency of 600 Hz and mono-axial. The DSI was calculated using the ratio between CPPF and IMF. For data analysis, the sample was separated into clusters by age. After the grouping, a descriptive analysis of the data and a comparison between the groups with p < 0.05. The sample was grouped into three groups (GA, GB, and GC) and one of the individuals did not enter the group, totaling 18 individuals in the analyzed sample. The comparison between the ages of the groups showed a significant difference and small and moderate effect size (ES), validating the cluster strategy. The CPPF and IMF variables showed increased values according to chronological age. CPPF showed a significant difference between GA-GB, (ES = very large) GA-GC (ES = very large), and GB-GC (ES = moderate). The IMF variable had significant differences between GA-GB (ES = moderate) and GA-GC (ES = very large). However, DSI showed significant differences only between GA GB (ES = small) and GB-GC (ES = very large). The CPPF and IMF variables had constant increases and distinct values with an increase according to age, and this did not occur for DSI. The difference between CPPF and IMF compared to DSI bring to light the variability in dynamics and proportionality between muscular force in the concentric phase and maximal force in the isometric regime during the developmental process over chronological age in soccer goalkeepers.

Complex visual-motor reaction of qualified goalkeepers in football

. The purpose of the work was to determine the reliability of the choice reaction test for monitoring the educational and training process of qualified football goalkeeper athletes.

The corresponding calculations were carried out using the analysis package of the MS Excel computer program and the functions of the Statistica computer package. The study covered 11 goalkeepers in the Ukrainian Premier League. Complex reaction time was measured at the beginning of training sessions in ten attempts. The result was recorded with an accuracy of one millisecond.&#x0D; It was found that the individual variation of the results of complex reaction time measurements was at an average level (V=3.8÷22.1%). A statistically significant difference (p&lt;0.001) was found in the complex reaction time between athletes (from 281.4±31.8 ms to 391.9±14.9 ms). The relative contribution of the difference in complex reaction time between athletes (28.5%) to the total variation was significantly smaller than the corresponding contribution of the variation between attempts (71.5%). According to the value of the intraclass correlation coefficient (IСС =0.747), the reliability of the latent time test can be estimated as acceptable. The test can be used for an individual approach in assessing the condition of goalkeepers in football and the appropriate management of his game activity.

Contextual factors in understanding the jumping performance of young football goalkeepers

The aim of this study was to examine the effect of various contextual factors, such as relative age, biological maturation, or competitive level, on the jumping performance of young football goalkeepers. Vertical jump performance was evaluated in a selection of goalkeepers (n = 110) from U-14 and U-16 category teams. The sample was categorized by relative age, biological maturation, and competitive level. The results revealed a trend in the overall sample towards an overrepresentation of goalkeepers born in the early months of the year. Maturity status influenced the most in jumping performance of young goalkeepers (SJ: F = 11.27, p < .001, ηp2 = 0.187; CMJ: F = 8.72, p < .001, ηp2 = 0.162; AJ: F = 8.37, p < .001, ηp2 = 0.146), while the birth quartile had no effect on the jumping performance in the sample. Statistical differences were significant for SJ and CMJ between competitive level groups in the U-14 group only. (F = 5.37, p = .008, ηp2 = 0.186) and CMJ (F = 4.54, p = .016, ηp2 = 0.159). This study showed a greater association between maturation and jumping performance in young football goalkeepers rather than with relative age, which could influence the selection process in this field position at early ages.

Game defense activity of top football goalkeepers - running out – evaluation and analysis

This article deals with the frequency of single player defensive playing activity (further SPDPA) of football goalkeepers running out, as monitored in a studied group and in sets of goalkeepers of both winning and losing teams. In addition, it focuses on an analysis of the dependence between the team's success in the match and the level of quality of the defensive game activity of football goalkeepers running out. The authors created a form enabling selected playing activities of the observed goalkeepers to be recorded. It was supposed that the goalkeepers of the losing teams would have a higher frequency of SPDPA running out - playing one on one and running out to the crosses. Such running out SPDPA had the greatest influence on the result of the match. The hypotheses were confirmed. The results of the analysis will be useful for trainers in training planning and match tactics.

Analysis of individual performance indicators of football goalkeeper

One of the most widely used strategies for performance analysis in different sports is notational analysis through direct observation of technical-tactical actions, which allows to understand the main indicators of sporting performance of the players, both individually and collectively. Football goalkeepers (GKs) are involved in the game differently when compared to the rest of the players in the team and, therefore, they develop different high-level and high-intensity tactical-technical actions. Therefore, the present work aimed to analyse the different performance indicators of football GKs through a search in the following databases: Web of Science (WOS), Scopus (Elsevier), PubMed (NIH) and, SPORTDiscus (EBSCO), until February 2023. The following keywords were used: "Football" or "Soccer", "Goalkeeper" and "Performance analysis". The results show that the main performance indicators are the percentage of avoided goals, the distribution of the ball at the goal kick as well as the number of offensive and defensive actions. Therefore, training sessions should be planned and implemented aimming to improve these skills.

Multivariate analysis of goalkeeper actions in youth football

There is a lack of studies investigating youth goalkeepers that implement variables that can allow researchers and coaches to better understand the performances of the goalkeepers. For this reason, the aim of the present study was to identify key performance indicators of youth football goalkeepers both defense and attack. The sample was composed of 902 defensive and 896 offensive actions from a convenience sample of 32 matches of 19 teams from the Spanish National Championship of Regional Teams U12. A notational analysis was carried out using an ad hoc instrument to register the technical-tactical actions. Validity was higher than .84. In addition, intra-observer reliability was higher than .90. Classification tree analysis was used to investigate which variables were best predictors of technical actions in defense and precision in attack actions of the goalkeepers. Results showed that in the attacking phase the actions that achieve higher values of precision were those when the ball was played to zone A length and both right and left sides (X26 = 542.034; p = .000). In defense, when the goalkeeper achieve higher values of saves were those when the shot was taken from out of the penalty area and no jump or drop was performed. The present findings contribute to evidence-based practice in fostering young goalkeepers.
