Influence of whole body posture and kicking motion of lower extremity on improving goal rate during the non-trap shoot in football

Abstract

Non-trap shooting, one of the soccer shooting skill, is an important technique for shooting in the penalty area and requires a high skill level. This study investigated the kinematic characteristics of the inside kick in non-trap shooting by comparing successful and failed attempts. We found significant differences between the successful and failed attemps in the joint angle of the supporting leg and in the whole body tilt angle in the failure group before and after the ball impact, indicating that their posture was unstable. Specifically, players in the failure group had a greater anterior-posterior body tilt before ball impact, suggesting that the flexed position of the supporting ankle and knee joints influenced this. These results highlight the proper control of the whole body posture and lower extremity joints necessary for successful non-trap shooting, giving soccer player new training metheds to develop their shooting skill. We identified the skill factors that contribute to effectively kicking the ball toward the goal in soccer.
