ZJKPendulumServe

张继科拥有十分优秀的正手发球技术
	ZJK has a very good FH serve technique

他的发球虽然出手慢, 但是旋转强, 隐蔽性强变化多
	Although in his service, the hand motion is slow but very spiny, well power-concealed with vast of variation

并且与随后的发球抢攻紧密配合
	And works closely with subsequent third ball attack

常常在发球局中占据主动, 给对手造成很大压力
	Usually serve to take the initiative, make a hug pressure to the opponent

今天我们就来分析一下张继科发右侧上旋球的动作要点
	Today, we will analyze ZJK’s right topspin serving stroke principles

要点 1： 腰部要带动前臂充分引拍, 打开击球空间
	Point 1: The waist should drives the forearm to fully backswing, wave into the space

要点 2: 击球前手腕充分外展, 为摩擦球提供加速度
	Point 2: The wrist then fully stretches, to brush the ball and provide acceleration

要点 3: 触球的侧下部, 尽量往侧部摩擦, 减少向上勾的幅度
	Point 3: Try to brush the lower-right part of the ball (inward brush), also try to reduce the height of the bounce

这样发出的侧上旋球落台后才不会往前拱
	This will give a side-topspin ball right after first bounce and won’t make it off the table on second bounce

与侧下旋球结合, 更加具有的似性和迷惑性
	Combine with the backspin at the beginning, the ball will have even more spin and confusing

要点 4: 张继科在发球时双腿弯曲幅度很大
	Point 4: ZJK, when hitting the ball, his two legs are bent down, wide open

充分下压并且前顶重心低压且稳定出球弧线
	Fully bend down with his head, lowering his core to stabilize and brush side of the ball

要点 5: 张继科的腰部回转动作保证了摩擦力量的集中性
	Point 5: The rotating back movement of ZJK waist proves that he focuses on the friction force amount applied to the ball

腰部一定要有控制手臂的感觉
	The waist must have control of the arm feeling

要点 6: 发完球后, 膝关节反弹, 迅速还原准备抢攻
	Point 6: After sending the ball, knees bounce back quickly to ready stance, prepare next attack

下面我们就来分析张继科发球以及发球抢攻的案例
	Next, let’s analyze ZJK serve as well as attacking serve examples

案例一: 对手直接吃发球
	Ex 1: Opponent directly attack the serve

情况1:发右侧上旋球到对手正手小三角
	Situation 1: Serve topspin to opponent’s FH small triangle

逼迫对手上步，很容易造成对方失误
	Force opponent to step in, very easy to create opponent’s mistake

情况2 :发右侧上旋球到对手中路
	Sit. 2: Serve topspin to opponent middle

对手很难出发力，会感到非常难受
	It’s very difficult for the opponent to exert force, also extremely to receive normally

让球朝着对方的右肩膀前进，很令对手感到犹豫
	The ball come in front of opponent right shoulder, make opponent feel extremely hesitant

情况2: 发右侧上旋球到对方反手大角度
	Sit. 3: Serve right-topspin to opponent BH wide angle

尽量把球发长发急，对方侧身容易被顶住
	Serve as fast and long as possible, makes opponent moves his body left to cover

又是大角度，对手反手回击又很难控制
	As there is wide open angel, it’s difficult for the OP to control his next BH

案例二: 对手接出半高球
	Ex. 2: OP gives half high ball

情況1:对手摆短冒高后直接暴挑
	Sit. 1: OP pushes short but high then directly FH flip kill

注意打出斜线和直线的变化
	Note to play cross and straight ball to add variations

情况2 ：正手直接拉冲对方正手大角度
	Sit. 2:  FH loop-drive directly into OP wide FH

一定要拉出力量和速度，刁钻的落点令对手无法防守
	Be sure to loop with power and speed, give no clue about the ball placement so that OP has no way to defend

情况3：正手拉冲对方反手位 （直接）
	Sit. 3: FH loop-drive to OP BH directly

可以增加身体和手臂的晃动来迷惑对方
	You can also trick the OP by increasing body and arm movements

在线路上直接令对手难以判断
	before ball contact moment, make OP difficult to judge

情况4:正手拉冲对方中路
	Sit. 4: FH loop-drive to OP middle

与正手位反手位的落点相互结合，增大对手防守的难度
	Combine with FH and BH placements alternating, increase OP defense difficulty

情况5: 反手暴拧对方
	Sit. 5: BH flip kill

和暴挑一样，暴拧也要注重直线和斜线的变化
	Just like FH flip kill, BH flip kill also varies between straight and cross court play

更要摩擦球的侧部，拉出较强的侧拐，增加出球的威胁
	Also loop the ball by its side, give a very strong & wide placement, and increase the threat of the ball

案例三: 对手挑打反手位
	Ex. 3: OP opening BH flip

情况1:对方挑打后形成相持抢得先机
	Sit. 1: The OP make an opening BH flip then goes into a rally

在相持中要抢先侧身发力变线才是得分的王道
	In the middle of the rally, be first to lean the upper body to change the ball trajectory to FH and win the point

情况2: 直接借力快顶对方中路
	Sit. 2: Directly borrow power to drive into OP middle

主要突出速度, 令对手措手不及
	OP will not able to react with his ball sudden speed

情况3:直接借力袭击对方正手空挡
	Sit. 3: Directly borrow power to attack OP FH open space

打出大角度，或者快速压制都能让对手无力回天
案例四：对手挑打正手位
	Use a wide-angle shot, or speedy shot to pressure and make OP impossible to return
Ex. 4: OP FH opening flip

当对手挑打正手后
	After OP flip FH

要用跳步迅速移位正手，不要使用交叉步
	Quickly bounce to FH position, don’t use crossover footwork

因为运用跳步可以更灵活的选择线路
	Since bouncing to FH could give more flexible ball placement

并且一定注意迎前抢高点将球快速拉回对方的大角度
	Pay attention to the high bounce incoming ball to fast loop to OP wide angle

案例五: 对手拧拉
	Ex. 5: OP BH flick

情况1:发右侧上旋短球到对手中路偏正手位置
	Sit. 1: Serve short right-topspin into OP middle, but more on his FH position

对手上步到正手位拧拉后，迅速回击对方反手大角度
	After OP steps to FH to make BH flick, quickly drive to OP BH wide angle

这样可以成功将对方 “撑” 开
	This stroke can be easily makes OP enlarges his open

如果形成了反手相持，则要首先发力或者侧身争得主动
	If it is a BH rally, firstly exert more force or lean the upper body for FH in order take the initiative

情況2 :对方拧辦后，直接反拉
	Sit. 2: After OP flicks, directly counter-loop

抢在前面形成正手的绝杀或者是连续进攻
	Take the chance for a FH kill shot or make continuous attack

案例六：对手接发球抢拉
	Ex. 6: OP attacks serve with a loop

即使对手先拉起来，张继科也能立即遏制住对手的进攻
	Even if OP loops the ball, ZJK still able to block his attack immediately

立刻压挡对手的中路，严重降低对手进攻的质量
	Use the block to pressure OP middle, severely reduce the quality of the OP next attack

然后伺机发力转防为攻
	Then wait a chance to switch from defense to attack
