Kinematical Characteristics of Accurate Penalty-Kicking for Turkish Football Players in Goalkeeper Confrontation

Abstract

This study aimed to analyze the kinematical characteristics values of accurate penalty-kicking for Turkish football players in goalkeeper confrontation. Fifteen male Turkish Regional Amateur League players (Age: 21.08± 1.56 years old) was scanned, by two video cameras synchronous in two-dimensional (2D), placed at optical axes X&Y. the best three tries of penalty kicking performance were analyzed by video analysis Dartfish 9.0 software. Standard statistical methods were used for the calculation of mean±sd, Pearson test for the correlations between all variables. A value of p-value ≤ 0.05 was considered a threshold of statistical significance. The results were shown in the ball contact phase that the distance pivot foot & ball factor has a statistically significant effect in producing accuracy (p-value=.001), and the interaction between two main factors namely the trunk and inclination body angles has a statistically significant effect with a p-value≤.05 in producing accuracy too. In addition, in the followthrough phase, we can see too the statistically significant effect in p-value≤.005 of the trunk angle, and in pvalue≤.05 of the thighs angle in producing accuracy. As a conclusion, it can be conveyed that the distance between the support leg and the ball is very decisive for the kinematic profile formed such as contraction of the abdominal muscles (trunk angle), the amortization process (the pivot leg angle), shot power (angle and length of the shot leg swing trajectory), where these aspects are significantly affected to the shot power, ball velocity and the level of accuracy.

The different influence of speed, agility and aerobic capacity toward soccer skills of youth player

“…This study examines the correlation between aerobic endurance and soccer skill, which shows a correlation on a small scale. It is believed that because soccer skills are strongly influenced by bio-motor aspects and high technical mastery, the involvement of aerobic endurance elements alone is believed to be insufficient to describe the level of correlation and its influence on soccer skills [17]. Therefore, the involvement of various bio-motor aspects, mastery of basic techniques is expected to be involved in further studies to be able to comprehensively describe the level of correlation with soccer skills.…”

“…The speed ability is required since an athlete needs to be active moving for dribbling, passing, attacking, and running around the field in a short time speed [16]. In the interrelation principles, speed in movement is also required to be able to produce power for kicking, jumping, and heading in combination with other bio-motoric components [14, 16,17]. Another statement shows that agility has close interrelation between speed, coordination and flexibility [18].…”

The impact of reaching the anaerobic threshold on some kinematic variables related to the accuracy of shooting the penalty kick among footballers

“…Football is one of the sport games that have a prominent position all over the world; indeed, it is the most popular sport in the world with 211 international football federations that are under the supervision of the international football federation (Abdelkader et al, 2021).…”
