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.
土耳其足球运动员在守门员对抗中精准点球的运动学特征
本研究旨在分析土耳其足球运动员在守门员对抗中准确罚点球的运动学特征值。15名土耳其地区业余联赛男性球员(年龄:21.08±1.56岁)通过两台同步摄像机在x和y光轴上进行二维(2D)扫描。采用视频分析软件Dartfish 9.0对三次射门表现最好的球员进行分析。采用标准统计学方法计算均数±标准差,Pearson检验各变量之间的相关性。p值≤0.05为具有统计学意义的阈值。结果表明,在球接触阶段,枢轴脚与球的距离因素对产生精度的影响具有统计学意义(p值=.001),躯干与倾斜体角度两个主要因素之间的交互作用具有统计学意义(p值≤)。生产精度也是05。此外,在随访阶段,我们也可以看到p值≤的统计显著效应。0.005的主干角,且p值≤。05的大腿角度在产生精度。综上所述,支撑腿与球之间的距离对腹肌收缩(躯干角度)、摊销过程(支点腿角度)、击球力量(击球腿摆动轨迹的角度和长度)等形成的运动轮廓具有决定性作用,这些方面对击球力量、球速度和精度水平都有显著影响。
