以往的高爾夫科學研究，非常普遍的將左肩頂點(Cochran & Stobbs, 1968)、人體肚臍眼後內的重心、胸腔骨中下緣的劍凸(Tomasi, 2008)或連結雙肩頂點的假想直線的中央點(Linning, 1994; Hume, 2005)，或雙肩的中央視為打擊精準的旋轉中心。作者王建智(1999)認為旋轉中心應該是在旋轉軸中的某一點，不可能將旋轉中心放在(脊柱之外的任何位置。即使近年也有其他高爾夫報告內容出現頸椎第七節的命名，但所偵測的是頸後外表（Simon et al.,2005 & Myers et al., 2008）的部位(marker)而並未涉及內部中心與打球精準的關係。於是進入研究學府學學習科學儀器的使用與動作數值的統計法(指導者相子元教授2000)，委請同學楊沛峰(2001)一起完成一年的測試工作。研究所畢業後，王建智又經六年以上的統計整理，將圓心少移、揮桿順序與手臂複擺形狀的打直球動作整理完成。
THE WORLD LEADING GOLF SCIENCE REPORT
Many qualitative observers (Cochran & Stobbs, 1968), writers or coaches in golf magazines have expressed unanimously that the instant rotation center at the impact stage was the left shoulder tip or the body center around the navel (Tomasi, 2008;Linning, 1994; Hume, 2005;)Consequently, the shoulder tips moving forward and allowing the shoulder line and its middle point(Simon et al.,2005 & Myers et al., 2008) to move ahead of the seventh cervical vertebrae (C7) was considered problematic, and the same phenomenon occurs when the shoulder line moves backwards. Although Coleman and Rankin and Myers et al., have attached markers on the surface of the C7 as the proximal end of the upper torso triple pendulum model, it was neither for rotation nor for precise impact analysis. Aside from the shoulders’ middle point and posterior point of the C7, a point near the sternum (Tomasi, 2008) was also considered as an instant rotation center. The point of the rotation center should be in the spinal axis and at the same height as the proximal end of the shoulder joining the C7. Therefore, it is feasible to assume that the rotation center was an inner center point of the C7, and the length from the inner center point to the distal end of the pendulum (clubhead) was the swing radius. This new finding has been reported by Tony, J.J.Wang and et al., (2002-2015).
The white dot (cervical seven inner center) is Tony,J.J.Wang`s leading report which is different from all used reports.
High speed digital cameras were used for capturing body and club motion, and the camera was for the impact location picture.
After body and club swing motion be captured by digital cameras or infurious light cameras, motion analysis software digitized them into numerical 3D motion (dot, line or angle in 3D positions), then these numerical 3D data (position/time) were put in SPSS for meaningful test. The result was not including the finish stage, RCP shift area is not over a 460cc wood driver sweet spot area.
