Good kicking technique is an important aspect of a soccer player. Therefore, understanding the biomechanics of soccer kicking is particularly important for guiding and monitoring the training process. The purpose of this review was to examine latest research findings on biomechanics of soccer kick performance and identify weaknesses of present research which deserve further attention in the future. Being a multiarticular movement, soccer kick is characterised by a proximal-to-distal motion of the lower limb segments of the kicking leg. Angular velocity is maximized first by the thigh, then by the shank and finally by the foot. This is accomplished by segmental and joint movements in multiple planes. During backswing, the thigh decelerates mainly due to a motion-dependent moment from the shank and, to a lesser extent, by activation of hip muscles. In turn, forward acceleration of the shank is accomplished through knee extensor moment as well as a motion-dependent moment from the thigh. The final speed, path and spin of the ball largely depend on the quality of foot-ball contact. Powerful kicks are achieved through a high foot velocity and coefficient of restitution. Preliminary data indicate that accurate kicks are achieved through slower kicking motion and ball speed values. Key pointsSoccer kick is achieved through segmental and joint rotations in multiple planes and via the proximal-to-distal sequence of segmental angular velocities until ball impact. The quality of ball - foot impact and the mechanical behavior of the foot are also important determinants of the final speed, path and spin of the ball.Ball speed values during the maximum instep kick range from 18 to 35 msec(-1) depending on various factors, such as skill level, age, approach angle and limb dominance.The main bulk of biomechanics research examined the biomechanics of powerful kicks, mostly under laboratory conditions. A powerful kick is characterized by the achievement of maximal ball speed. However, maximal ball speed does not guarantee a successful kick: in each case, the ball must reach the target. As already explained, when the player is instructed to hit the ball accurately, joint and segment velocities are lower as opposed to a fast and powerful kick performance. It is therefore apparent that future research should focus on biomechanics of fast but accurate kicking.
良好的踢球技术是足球运动员的一个重要方面。因此,了解足球踢球的生物力学对于指导和监测训练过程尤为重要。本综述的目的是检查最新的关于足球踢球表现的生物力学研究结果,并确定目前研究中的弱点,这些弱点值得在未来进一步关注。作为一项多关节运动,足球踢球的特点是踢球腿的下肢节段从近到远的运动。角速度首先通过大腿最大化,然后通过小腿,最后通过脚最大化。这是通过多个平面的节段和关节运动来实现的。在后摆过程中,大腿主要由于小腿的运动依赖性力矩而减速,在较小程度上,通过髋关节肌肉的激活而减速。反过来,小腿的向前加速是通过膝伸肌力矩以及大腿的运动依赖性力矩来实现的。球的最终速度、路径和旋转主要取决于球脚接触的质量。有力的踢球是通过高脚速和恢复系数来实现的。初步数据表明,准确的踢球是通过较慢的踢球动作和球速值来实现的。关键点足球踢球是通过多个平面的节段和关节旋转以及节段角速度的从近到远的顺序来实现的,直到球撞击。球脚撞击的质量和脚的机械行为也是球的最终速度、路径和旋转的重要决定因素。在脚背最大踢击范围内,球速值在 18 到 35 毫秒(-1)之间,具体取决于各种因素,如技能水平、年龄、接近角度和肢体优势。大多数生物力学研究都考察了在实验室条件下强有力踢球的生物力学,强有力的踢球的特点是达到最大球速。然而,最大球速并不能保证成功的踢球:在每种情况下,球都必须到达目标。正如已经解释的,当运动员被指示准确击球时,关节和节段速度会降低,而不是快速有力的踢球表现。因此,很明显,未来的研究应该集中在快速但准确的踢球生物力学上。
