多年來政府推展體育的兩大方向，一為提倡全民體育；一為積極培養優秀 選手。在培養優秀選手方面，以國際體壇競爭激烈的今天，「體育即國力」已經 成為大家的共識。現今已邁入二十一世紀，各國為提升國際聲譽，不斷致力於 培訓優秀運動選手，參加國際運動賽事及錦標賽為國家爭光。 目前我國優秀的網球選手漸漸在國際大賽中嶄露頭角，如詹詠然、盧彥勳 等；青少年選手更不勝枚舉，如曾在澳洲網球公開賽青少年組男子雙打取得優 異成績的謝政鵬及楊宗樺，由此可看出網球運動在國內漸被重視且具有成長的 趨勢。以目前縱橫國際網壇的明星選手來說，絕大部分都是在青少年時期即嶄 露頭角，旋即進入職業網壇成為頂尖好手。所以，青少年選手的培育，不僅是 儲備正式選手，也是推廣網球運動往下扎根的基礎工作。因此，一名經驗豐富 的專業運動教練對於培養傑出的運動員而言非常重要。 因此，身為網球教練工作的一員，探討網球運動教練所具備之專業能力， 以提供網球運動教練有更完善的專業素養，提昇運動教練技術水準，促進網球 運動發展的品質，更作為未來運動教練培育課程的參考，進而將網球運動推向 國際舞台。
