散打两种侧踹腿攻击效果的对比分析

Comparative Analysis of Attack Effects of Two Sorts of Side Kick in Sanda

从运动学和解剖动力学的角度 ,采用影片分析法对散打正向提膝侧踹腿与侧向提膝侧踹腿两种不同踢法的特点、优劣及其机理进行探讨。结果发现 :正向提膝侧踹腿的攻击时间和平均速度均优于侧向提膝侧踹腿 ,但击中踢靶的瞬间速度却劣于侧向提膝侧踹腿 ,两者差异均达非常显著性 (P <0 .0 1)。正向提膝侧踹腿比侧向提膝侧踹腿合理主要在于提膝速度快 ,攻击时间短 ,隐蔽性强 ,动作灵活易于完成 ,提膝时身体正向表面面积较小 。

The characteristics, advantages and disadvantages as well as mechanism of the front sidekick with the knee raised and lateral sidekick with the knee raised in Sanda were analyzed by film analysis and discussed from the views of kinesiology and anatomical kinetics. It was found that the front sidekick with the knee raised is superior to the lateral sidekick with the knee raised in the attack time and the mean attack velocity, but is inferior in the instantaneous velocity when hitting the target. There was significant difference between the two sorts of sidekick (P<0.01). Front sidekick with the knee raised is preferable in that the speed of raising the knee is quicker, the attack time is shorter, the concealment is better, the movements are flexible and easy to perform. The frontal surface area of the body is smaller, which is propitious to defence.
