This study aimed to identify the effects of different kick types on the relationship between kicking leg muscle activation and ball velocity. The muscle activation of selected knee extensor and flexor muscles of 10 amateur soccer players were measured using electromyography during the performance of six maximal soccer kick types. The highest ball velocity was achieved by the instep kick (96.2 km/hr-1), followed by the lofted kick, the inside curve kick, the outside kick, the outside curve kick, and finally the inside kick (81.3 km/hr-1). There were significant positive correlations between muscle activation and ball velocity for the vastus lateralis and lofted (0.765), inside curve (0.792) and instep kicks (0.788), and for the gastrocnemious with the outside kick (0.796). Non-significant correlations between muscle activation and ball velocity exhibited a trend such that they were positive for the vastus medialis and vastus lateralis but negative for the biceps femoris and gastrocnemious for inside-foot-dominated kicks, while this trend was reversed for outside-foot-dominated kicks. According to results, the noted trends can be explained by the change in muscle activation patterns required to orientate the foot for each type of kick; this has implications for players’ training activities.

踢腿类型对踢腿肌肉激活与球速度之间关系的影响

这项研究旨在确定不同踢腿类型对踢腿肌肉激活与球速度之间关系的影响。在6种最大足球踢类型的表现过程中，使用肌电图仪测量了10名业余足球运动员所选膝盖伸肌和屈肌的肌肉激活情况。脚背踢（96.2 km / hr-1）达到最高球速，然后是放样踢，内弯踢，外踢，外弯踢，最后是内踢（81.3 km / hr- 1）。股外侧肌和仰卧肌（0.765），内侧曲线（0.792）和脚背踢（0.788）以及腓肠肌和外侧踢（0.796）的肌肉激活和球速度之间存在显着正相关。肌肉激活与球速之间的非显着相关性呈现出一种趋势，即它们对内侧腓肠肌和外侧腓肠肌呈正相关，而对于股二头肌则呈负相关，而对于以脚内为主的踢腿则是消化性的，而对于外侧脚则相反。 -踢腿。根据结果​​，可以通过为每种脚踢定向脚所需的肌肉激活模式的变化来解释上述趋势。这对球员的训练活动有影响。可以通过每种脚踢使脚的姿势所需的肌肉激活模式的变化来解释上述趋势；这对球员的训练活动有影响。可以通过每种脚踢使脚的姿势所需的肌肉激活模式的变化来解释上述趋势；这对球员的训练活动有影响。
