研究目的:探討新制實行後，世界頂尖男子單打選手發球和接發球技術的使用情形及落點和路線的變化。研究方法：以立意取樣，選取2006 年國際羽球總會認定之五星投以上賽事，進入前八強之選手，研究樣本共七場比賽資料進行分析，以次數分配及百分比描述發球和接發球技術型態及落點的變化，並使用卡方的適合度檢定，進行統計考驗。研究結果：當前世界級男單選手的發球型態及技術以反手拍發短球比例為最高，而在發球落點的分佈以靠近中線的中線一區的選擇為優先；在接發球技術路線及落點方面以直線短球為主，擊球落點以選擇前場的2 號區為最高。結論：新賽制實行後，雙方主動攻擊意識更為強烈，使得選手在前場區的爭奪越趨激烈，在發球和接發球的技術主要都以短球為主，擊球落點也以前場區域為第一優先考量。
