Biomechanical analysis of accuracy penalties-kicking performance for Turkish Soccer players: Group-based analysis without goalkeeper

Abstract

Background and Study Aim. It is stated that kinetic performance factors are important in the successful execution of accurate kick-penalties, thus, its offer excellent performance despite a substantial kinetic method change in their implementation. The aim of the study is to biomechanical analysis of accuracy penalties-kicking performance for Turkish soccer players. Material and Methods. The study group consisted 15 male students of Turkish Regional Amateur League players (Age: 21.08± 1.56 years old). Two video cameras placed at optical axes X&Y filmed penalty-kick performance of the subjects. we analysed the best three scores by video analysis Dartfish 9.0 software. Standard statistical methods were used for the calculation of mean±SD. the Statistical significance at p<.05 for Pearson product—moment correlations. Results. Accurate penalty-kicks showed significant positive relationship of knee Pi angle value in backswing, ball Contact phases, trunk angle value in ball contact with the accuracy at p<.01. Significant negative relationship of inclination_body angle value, time of foot contact at p<.01, and distance pivot foot&ball value at p<.05 in the follow-through phase. Conclusion. Such knowledge should aid in clarify the relationships between variables of penalty kicking during The performance phases and accuracy. the present preliminary investigation of accurate penalty-kicks performance indicates Support-leg characteristics demonstrated in knee angle values an important factor in Backswing, Ball Contact phases with the accuracy of penalty kicking. also, the Foot Contact time and Inclination_Body angle in that.
