Abstract

This study aims to elucidate the distinct characteristics of foot motion at ball impact, which affect the lateral ball launch direction in soccer instep kicking. Seven experienced male university soccer players each performed instep kicks towards a standard goal 11 m away, divided vertically into left, centre and right target areas (six kicks per area). Three high-speed cameras captured the foot and ball behaviours during ball impact at 2000 Hz. Multiple regression analysis was conducted with the lateral ball launch direction (dependent variable) to identify the key foot behaviours (independent variables) that contribute to the lateral launch angle of the ball. Consequently, the regression model (R² = .91, p < .001) indicated that the foot contact point on the ball (β = -.649, p < .001) and the instep facing direction at ball impact (β = .324, p < .001) significantly predicted the ball direction, whereas the foot swing direction did not (β = .078, p = .312). These findings indicated that manipulating the foot-ball contact point and foot posture at ball impact is necessary to control the ball direction. Players strike the ball on the side opposite the target and orient the dorsal surface of the foot towards the intended direction.

足球脚背踢在不同球方向上的足部冲击行为。

摘要本研究旨在探讨足球脚背踢中足部运动在球撞击时的不同特征对球侧向发射方向的影响。7名经验丰富的男大学生足球运动员每人向11米外的标准球门进行脚背踢，垂直分为左、中、右三个目标区域（每个区域6次）。在2000赫兹的频率下，三个高速摄像机捕捉到了球撞击过程中脚和球的行为。以球侧向发射方向（因变量）进行多元回归分析，确定影响球侧向发射角度的关键足部行为（自变量）。因此，回归模型(R2 =。91, p p p p = .312)。这些发现表明，控制足球接触点和球撞击时的足部姿势对于控制球的方向是必要的。球员在目标对面的一侧击球，并将脚的背表面朝向预定的方向。

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
