本研究目的在探討國小桌球選手知覺教練與運動員之關係構面、教練之領導行為與訓練選手之滿意度之相關與影響，並試圖建構其運動成績之預測模型。以臺北市四所國小桌球校隊作為研究的對象，共獲得有效樣本99 份，所得資料以變異數分析及C5.0 決策樹演算法的資料探勘進行統計分析。結果發現這些國小桌球小選手必須在3、4 年級就要開始培養與教練的各種關係，未來才可能在運動競技場上發光發熱，對於這些有心的小選手，超過兩年球齡持之以恆的訓練，對桌球運動是最重要的，若想要更早能夠代表學校參加校外比賽，則需要付出更多的時間與心思才能成功，然而對於要爭取優秀的比賽成績，則必須增加個人先天的素質加以考量，可以得到最佳的預測結果。

This study was aimed to explore the associations and influences among the coach-athlete Relationship, the leadership behaviors of the coaches and the satisfactions of the athletes in the primary school table tennis, and tries to construct the prediction model of its athletic achievement. The study objects was from the four primary school table tennis teams in Taipei. A total of 99 effective samples were obtained and these datas were analyzed by variance analysis and data mining of C5.0 decision tree algorithm. The results showed that these young athletes must begin in the third and fourth grade for bulding the relationships with the coach, in order to maybe glow fever in the sports arena in the future. For these distinguished young athletes, more than two years persistent training of the table tennis is the most important. If you want to earlier on behalf of the school to participate in off-campus competition, you must need to pay more time and mind to succeed. However, in order to strive for outstanding results, you must increase the consideration of the personal innate qualities for getting the best predictive models.
