如何在击球过程中保持身体重心的稳定

<pre style="ADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">遇到一个这样的现象：球友在击球过程中不知不觉的就直起了腰，有时候还有明显的后仰，这样不但发不上力量，而且球的落点也控制不好，球容易出界或者下网。  我们在说打球的准备姿势时都说过，两膝微屈，含胸收腹，这么做的目的就是为了让上身保持前倾，这样整个身体的重心才能保持稳定。在击球时，才能合上力，把身体的力量用来击球。  在练习时保持重心的稳定是比较容易的，但是，在比较紧张的比赛中，大部分的球友都有不同程度的紧张，随着身体肌肉的紧张，就很容易忘记去用重心打球，变成了抡胳膊打球了。也就出现了上述我的球友的问题。</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">那么如何去做呢？  我觉得可以从几个方面注意：</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">一是，自己不断提醒自己，每打几个球后，自己就自查一下，是否用重心击球了，是否有上身后仰出现；</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">二是，不管是发球，接发球，还是移动中相持球，都检查自己是否将重心放到了前脚掌；</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">三是，注意放松，身体发紧了自然不容易控制重心；四是，打球注意迎前，特别是拉弧圈，这样重心自然就主动前移了。  如图王励勤对柳承敏的比赛，1图为反手拉球，2图为正手劈长，大家观察他们两个运动员，不管是进攻方还是防守的一方，其上身都是保持前倾的姿势，这样才有利于快速移动和发力攻球。</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">&nbsp;</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">&nbsp;</pre><pre style="PADDING-RIGHT: 0px; PADDING-LEFT: 3px; FONT-WEIGHT: normal; FONT-SIZE: 14px; PADDING-BOTTOM: 0px; MARGIN: 0px; WORD-SPACING: 0px; TEXT-TRANSFORM: none; COLOR: rgb(0,0,0); TEXT-INDENT: 0px; LINE-HEIGHT: 24px; PADDING-TOP: 0px; FONT-STYLE: normal; LETTER-SPACING: normal; POSITION: relative; BACKGROUND-COLOR: rgb(249,252,254); TEXT-ALIGN: left; FONT-VARIANT: normal; WORD-WRAP: break-word; orphans: 2; widows: 2; webkit-text-size-adjust: auto; webkit-text-stroke-width: 0px">&nbsp;</pre><br/>[upload=jpg,zuhe.jpg][img]
