第一章 高爾夫動作與打直球的因果關係
作者 王建智
打直球的因果關係乃是指正確的重心碰撞與動作好壞的關係。如欲獲致正確的重心碰撞，則必須球桿頭在上桿、下桿與送桿期的兩側桿平面一致。要揮出一致的揮桿平面，則揮桿順序與其節奏、身體旋轉時圓心少移、雙手臂形狀皆需正確。以上簡稱三項動作(因)與一致的揮桿平面(果)的因果關係，經由王建智測試報告後出版(半揮桿八周 鐵桿木桿打直球)。
Chapter 1. The correlation between motion factors and ball out straightly.
Written by Tony,J.J.Wang.
The result of a ball out straightly is regarded with the correlation of a better swing motion controlling the gravity point of clubhead to impact a ball center mass. One who want to make a correct impact, he has to swing the clubhead on the right (up swing) and left (down and follow through) same plane. For swing the clubhead on a same plane, the swing sequence and its tempo, the least shift of body rotation center point (RCP) and the correct arm style should be perfect. The above is named as 3 motions (factors) vs. a steady swing plane(result), it has been reported and published from the base of Tony`s lab studies.

一、打直球的結果說明(圖示1)。
球桿頭的重心撞擊在球重心的正下方而造成球直向飛行。但若它碰撞球重心的兩側則產生左右曲的側旋球。球桿頭重心撞擊於球的不同位置。
I. The result of a ball out straightly (Figure.1).
The point of gravity of clubhead impacts perpendicularly beneath the mass center of a golf ball to launch it out straightly along the target line. If not that but on the sides of ball mass center, the ball would fly out with a hook or slice directions caused by the side impact. Figure 1.The gravity of center point of clubhead impacts on the ball different locations.

(1)何謂揮桿平面? 何謂揮桿路線?
●有關揮桿平面(圖示2-4)。
球桿頭重心軌跡在左右兩側的移動稱為「矢狀面揮桿平面」。而當正確的碰撞時，上桿、下桿與送桿期的球桿頭重心軌跡是一致的揮桿平面。許多全球著名的經驗法則的知名教練認為下桿的平面並需比上桿平面低，是一件嚴重的錯誤。王建智了解此錯誤乃是因他們的攝影機架設角度的錯誤所致的觀察錯誤，因而他創立了全球未知的攝影法(隨後此文章與影帶將超連結於此)。
●有關揮桿路線(圖示5-10)。
以下的圖示是揮桿者使用五號鐵桿揮出直球時的上桿、下桿與送桿的揮桿平面是相同的，而此揮桿平面是一點十五分的方位。在上方往下的攝影機同步於右側攝影進行拍攝時，則呈現上的弧線大於下桿的弧線的情形而被稱為「水平面揮桿路線」。上桿期右肘離開身體所以弧線大而下桿期右肘貼近身體所以弧線小。

(1)What is the swing plane? And what is the swing route?
●About the swing plane(Figure.2-4).
The path of the gravity of clubhead on the right upswing and down to the left follow through is named as “a sagittal swing plane”. And once the normal impact occurring, the swing plane of the right and left is the same. There are many world famous of skillful experienced coaches thought the down swing plane should be lower than that of upswing is quite a serious mistake. Tony knows they made from the wrong observing from the wrong camera capturing positive on the swinger`s right side, therefore he invents a world unique of capturing skill for golfers (the article and film will be super linked here soon).
●About the swing plane(Figure.5-10).
The following figures show out that swinger using iron 5 to swing out a ball straightly under his clubhead on the same plane whenever at up, down and impact to follow through stages, and the plane orientation is one point fifteen clock. At the same time, the other fixed camera on the top which simultaneously with the right sagittal side camera in capturing that shows clubhead shift a wider path at upswing and a smaller one at down swing and above mentioned is called “ horizontal swing route or path”. For the right elbow separates against the body, the path it wider. And on the contrary, it back attaches body forming a smaller path at down swing.
(2)問題詢答
Q1：許多球友甚至於選手的動作怪怪的但卻能打出直球?
A1：這是因為擊球前後一小的揮桿平面底部一致，但一小段之外的中與上部揮桿平面不一致。這樣的怪動作雖可控制擊球前後一小段的正確而打出直球，但卻不是很穩定。
Q2:不同球桿的揮桿平面的角度相同嗎?
A2:不相同。不相同的原因是球桿長短所致，但動作是相同的。除非! 您還不了解正確動作的內容。
Q3:許多著名的職業教練在教學影帶中公開說明了下桿的平面比較低而送桿的平面比較高?
A3:即使這些教練曾經有打球冠軍的技術經驗但仍須自修。此嚴重錯誤的解釋是來自於他們擺錯了揮桿者右側的攝影鏡頭的位置所致。
Q4:如果作者認為球飛行尾端必須是直的，那麼尾端小左曲與小右曲的球不好的嗎 ?
A4:是的，你必須打出尾端畢直的球。唯有直球才能計算出球被不同的側風強度吹偏多少。也唯有直球才能計算出某地形影響球落地的滾動方向與滾動距離。例如：你本來可以將球往球洞的直線當成目標線，但是有一陣向左邊吹的風會將球往左邊吹偏1碼而你的直球就要往球洞右邊1碼來設定成目標線。再加上球若落於右高左低的果嶺而足以讓球向左滾1碼，那麼你必須將目標線往洞口右側2碼來設定。不是這樣的飛球品質是無法如此精算的。側旋球的多少曲度是無法預期的也很難被優秀的選手所控制，更遑論及風與地形等因素的影響了。
(2)Q/A：
Q1：Some of the amateur and professional players swing out ball straightly but those motions looked very strange?
A1：Shifting clubhead on the lower swing plane section (a small area before and after impact) is the same plane but out of the area to the middle and upper sections is not. Some strange motion those control a correct small section before and after impact can also swing out ball straightly but not steady.
Q2: Are different clubs swing the same corner degree of swing plane?
A2: They are not. The different swing plane is caused by the different club length but the swing motion is the same.
Q3: Why many famous professional coaches explained in the public films that the down swing plane should lower than that of the upswing?
A3:Event of those coaches are famous from their used skill of championship but they need to do more study. This very wrong explanation was from their un-proper setting the camera position on swinger`s right side.
Q4: Accordance with writer`s MSG here that the end ball flight should be straight, so a little hooks or fade ball flight is no good. Isn`t it?
A4: Yes, you must swing out a ball forward to the end straightly.
Only a ball forward to the end straightly can be calculated by different intensity of side wind. Also, when it land on the ground can be calculated out of its rolling direction and rolling distance affected by the ground conditions. For example, you could have swung the ball into the hole which accordance with the target line to the hole but a side wind blowing the ball to the left 1 yard of hole so as the target line should be considered to set at the right 1 yard of hole. Coupled with the ball landing on the right high slope which affects ball left rolling 1 yard, you have to make a precise target line of 2 yards of hole right. Without this good quality of ball flight, you could not precisely set a hole in one target line. How many bending degree of a side spin ball is unpredictable and not easy be controlled by an elite player, never mentioned about we add the other factors of wind or ground affects.
二、打直球的動作(原因)說明。
如果兩側的揮桿平面要一致，則揮桿動作要正確。正確的揮桿動作有三項 : (1)揮桿順序與其節奏要正確，(2)身體旋轉過程必須讓圓心極少移動，(3)雙手臂的正確形狀。然而，好的身體柔軟度比較容易完成以上正確動作內容。
II. What motion factors can control a rebounded ball out straightly?
If the degree of swing plane on swinger`s right and left side are the same, the swing motion must be perfect. The perfect swing motion includes the flowing 3 factors： (1)the swing sequence and its tempo must be correct, (2)the least shifting of the RCP during body rotation and (3) arms style should be correct. Meanwhile, a good body flexibility helps for the above 3 performances
(1)身體旋轉過程必須讓圓心極少移動(圖11)。
圓心到球桿頭重心的直線為揮桿半徑，若圓心移動則球桿頭的軌跡不穩定(揮桿平面不穩定)而且撞擊不精確。本書作者王建智(2002)領先全球高爾夫科學家，測試出揮桿圓心乃是人體頸椎第七節的內部中心點。
(1)The least shift of the body rotation center point (RCP-Figure.11)
The length of swing radius is from the RCP to the clubhead center mass, therefore the RCP`s move will lead clubhead on a unstable swing plane which result with a rough impact. Writer ( Tony, J. J. Wang. 2002) is leading all golf scientists around the world to declare the first finding of golf swing rotation center point is the inner center point of cervical seven (C7) .
圖示11(Figure.11)
(2)揮桿順序與其節奏要正確(圖12)。
上桿頂點的最大重量在右腳、下桿初期最大重量在左腳、然後撞擊。這是一種揮桿順序，而也有固定的動作節奏，簡稱「右腳→左腳碰」。此最新定義的揮桿順序由本書作者發表測試報告而領先全球(2001)。
此3D範例是下桿初期最大重量在左腳時為584.98牛頓，此時球桿頭仍在半空中而右膝已在雙腳中央。東方人的典型身材乃是上身長於下身，所以左腳承受最多重量時(1)，右膝剛好過體中(2)而球桿頭尚在半空中(3) ，然後才讓球桿頭下降撞擊球。
上身肩與臂早於下身腿與腰發動下桿，會產生右膝未過體中就先發生了撞擊的錯誤揮桿順序，而它最常導致於球桿頭在揮桿平面的外側下桿。改變此錯誤的下桿動作順序的要領是：上身的肩、臂與腕要放軟，以使桿頭重量撞擊球而不是用腕力擊球。此外，可以假想成右膝是打擊面而讓右膝先撞擊球(過體中)然後才讓打擊面撞擊球。你很難想像，資深的巡迴賽選手在下桿到送桿期段，右肩的肌肉力量僅有8%，而右手腕肌肉力量是被動的力量來使球桿頭撞擊球。
圖示12(Figure.12)
(2)The swing sequence and its tempo should be correct (Figure 12).
The vertical max ground reaction force on right foot when at the top swing, and to the left foot at initial down swing, then to impact is called a swing sequence. A swing sequence is the calculation of motion-time sequence so as the tempo be existed. A swing sequence be named “right foot-left foot-impact”by Tony who is leading the world study to report it in the Journal of Sports Science in in Taiwan (2001) .
The sample of this 3D stick figure shows out the max ground reaction force on left foot at initial down swing is 584.98 newton, and at the same time that the clubhead is on the middle height of the body and the right knee is at the central position among the feet. The typical orient stature is upper body longer than lower body so as the motion skill of the max vertical force on left force at down swing ① need to be cooperated with the right knee on the middle of feet ② and then to impact ③.
If you rotate the upper shoulder and whip arms before you left twist lower legs and left pivot hips during down swing, the wrong sequence will occur as an impact before right knee at the middle of feet (an impact before the max vertical force on left foot) which mostly let the clubhead goes outside of the normal swing plane at down swing. The key of amending the wrong swing sequence is to relax the upper shoulders and arms muscles as you can feel the impact is based on the clubhead weight but not the muscles` strength. Besides, you can try to imagine that the right knee is a clubface to impact ball first (means the right knee goes through the middle position of feet first) and then the real clubhead to flow the impact. You will very hard to know that the senior PGA tour players only using 8% MMT of right shoulder strength at down swing and impact stages, and right wrist muscles is a passive strength when at impact.
(3)雙手臂的正確形狀。
手臂形狀是否正確乃包括兩個重點定義；一是打擊面方正的手形，二是正確手形而使揮桿平面穩定。以上作者整理成「王氏方正打擊面之手臂定義」。
●有關方正打擊面的定義(圖13)。
方正打擊面被建立於中勢握姿，而打擊面必須垂直於胸線。如圖13所示，除了①、②與收桿期之外，打擊面與胸線呈九十度。
●有關打擊面與左手臂(圖14)。
左肘與左腕呈現平直時才有機會垂直於胸線，同時讓球桿頭行駛於正常的揮桿平面上。如圖14所示：左手拇指在握把右側(強勢握姿)是左腕不平直，不平值的左腕將使球桿頭陡峭於揮桿平面之前。此時若以胸線為基準線來檢查打擊面，則此打擊面是偏向於胸線左側小於九十度。

圖示14(Figure.14)
(3)The arms style should be correct.
The proper arms style is defined by two key factors in definition；one is the style can control the clubface at a square impact and the other is to help the clubhead on a steady swing plane. Tony, J. J. Wang who sorted the above mentioned as “Tony Wang`s golf arm style vs. square impact clubface”.
●About the square impact clubface (Figure.13).
The square impact clubface based on the neutral grip and the clubface should perpendicular on the chest line. See figure 13, the clubface line is 90 degree on the chest line besides the ①, ② and finish stage,
●About the orientation of clubface vs. left arm style (Figure.14).
A flat left elbow and wrist joints could have chance to set a clubface line with 90 degree on the chest line and also can fix a clubhead on the normal swing plane. See the Figure 14, the left thumb attaches on the right side of the grip (strong grip) is not the flat wrist which lets the clubhead goes up and ahead of the normal swing plane at upswing. At this movement-time, we check the clubface line under the base of our check line can find out that the clubface line is left down on chest line showing the degree is smaller than 90.
