用力学的方法分析踢球技术,可以帮助我们理解与改进技术动作,寻求最佳足球技术水平的发挥和取得良好的技术效果。因此用力学原理分析对足球某些技术动作的影响是不容忽略的重要环节之一。 踢球有多种脚法,球的路线变化也很大,今天仅就足球正脚背踢球技术、踢弧线球的原理和接传球时力的合成谈些个人意见。 一、正脚背踢球技术的分析: 正脚背踢球的力量大小与摆腿的幅度和速度有重要的关系。摆腿的动作分为:后引腿、前踢、前摆三个部分。根据肌肉的起止点进行分析,踢球腿后引时,臀肌、股后肌群收缩,而屈大腿的髂腰肌和伸小腿的股四头肌则被拉长。这一准备动作使踢球腿以较大的动量传递给足球,使球快速飞
Mechanics analysis of kicking technique can help us to understand and improve the technical action, to seek the best level of football technology to play and obtain good technical results. Therefore, using mechanics to analyze the influence of some technical actions on football is one of the important links that can not be ignored. Kick a variety of footwork, the ball changes the course is also great today, only the football is the instep kicking technique, the principle of kicking arc ball and then put the ball when the synthesis of some personal comments. First, the instep kicking technique analysis: the strength of the instep kicking ball and the leg swing amplitude and speed have an important relationship. Legs movements are divided into: after the lead leg, kick before the three parts. According to the analysis of the starting and ending points of the muscles, after the kick leg kick, gluteal muscle, posterior muscle contraction, and flexion of the iliopsoas and extension of the quadriceps were stretched. This preparation moves the kick leg to a greater momentum transfer to the football, the ball quickly fly
