自由泳视屏教学(世界名将本科)-两次划臂六次打腿(02)

猪八戒

(注:视屏下是中英文对照)


我们将在这里简要讲述划臂技术和我游泳时的想法。让我们来看看手部动作。看上去有些问题，但是我想当手部伸到我面前时，我要让手指指向池底。我的经验是划臂时他们总是在向后推水，直到划过臀部，肘部始终高抬。
(We're just going to briefly talk about the arms stroke and the technique and what I think about when I am swimming. Here we're looking at the hand. Now they're very questioning but I think about when I swim my freestyle, my hands get in front of me and I want to put my finger tips down towards the bottom of the pool. That is my experiences are always pushing back all the way through my stroke, all the way pass my hips, where should I keep my elbows high throughout my stroke.)

分析与研究:
　　１、与澳大利亚飞鱼索普相比，本科的自由泳划臂方式应该是“Ｓ”型划水路线，它的好处是加长了划水长度，从而取得更好的划水效果，为了保证划水长度，在移臂时手要尽量向前伸，划的时候切忌划“半程水”，一定要划到位，即划过臀部；
　　２、划水时，要尽量保证五指伸直，掌心指向池底，即与水平面垂直，并正对着身后的方向。
　　３、再一个重要概念是“高肘”，高肘有利于肩部肌肉群的发力。
