本研究欲比較網球技術與心理素質與網球比賽勝率之關聯性，以及不同天分之男網選手的差異，並檢驗重大勝利能否影響選手之生涯。實證結果顯示，大多數的網球技術都和比賽勝率顯著地正相關，而有天分的選手於大多數網球技術之表現優於天分較差的選手。另外也發現選手得到ATP之賽事冠軍後，可以提升網球技術與心理素質；但在得到大滿貫(Grand Slam)賽事冠軍之後卻會退步。本研究結果亦顯示雖然攻擊、防守與心理素質對選手的比賽結果都有很大影響，但在贏得ATP級冠軍之前攻擊技術是影響比賽勝率最大的因素；而贏得大滿貫賽事冠軍之後防守技術則成為最重要的勝率影響因素。研究結果顯示獲得重大勝利之後確實會增加職業男網選手之信心。 / This study tries to examine the tennis skills and mental toughness associated with winning percentages, compare the performance difference between talent players and less talent players, and find out how a major win can affect players career. The empirical results suggest that most of the tennis skills and mental toughness are positively and significantly associated with winning percentage. Talent players have better performance than those less talent players in most of tennis skills. The study also finds that players can improve offensive and defensive skills and mental toughness through winning an ATP title, but get worse after winning a Grand Slam title. The research findings suggest that before winning an ATP title offensive skill is as important as defensive skill for a player to gain more winning percentage, however, after winning a Grand Slam title defensive skill is the most important skill to win more winning percentage, although defensive skill and mental toughness are still play an important role for winning more percentage. The research concludes that a major win does enhance a player’s confidence.
