目前科技的發展與進步給桌球運動帶來了快速的發展，同時隨著國外職業化的進步，使桌球的速度越來越快，旋轉越來越強，導致擊球來往的回合越來越少，為了改變這種狀況，國際桌總採取了新的規則讓桌球比賽增加回合，使桌球比賽更具觀賞性，2000年雪梨奧運會後，國際桌球聯合總會對桌球的比賽規則進行了重大修改：將原直徑為38mm的球改為40mm，從2001年起實施每局11分制，改變了沿用近百年的每局21分的規則，接著在2002年的9月1日起，在正式比賽實施無遮檔發球的新規則，桌球規則的變化引發出來許多新的課題。本研究主要對規則改變後對運動員的技戰術、打法、身體素質帶來的一些相關影響，分別作分析和探討，期能協助運動員與教練在比賽中獲得佳績。
