本研究探討網球選手青少年與職業最佳排名時間分析，從國際網球協會(International Tennis Federation , ITF)官方網站撰寫Excel VBA程式擷取選手資料，總共擷取男、女選手121,714人(男性83,840人、女性37,874人)資料，經剔除無效資料(出生年1930年之前)後，區分年齡層及排名分類，統計各年齡層，不同選手的青少年與職業排名成績之間的關聯性分析。經研究分析結果發現：1.各年齡層選手人數男性多於女性，並且男女年齡越低人數越多。2.青少年及職業最佳排名平均年齡，ITF前10名男性17.82歲、女性16.82歲，ATP/WTA前10名男性25.18歲、女性23.47歲；女性選手比較年輕就可以達到最佳排名。3. 男女選手各年齡層職業前100名人數比例都是以具有ITF前10名者為最高，並且女性人數比例高於男性；而在20歲以下男女選手人數比例都最低，顯示ITF排名愈高者，相對職業網球發展優於其它排名分類，並以此為贊助挑選對象，應可獲得預期成效。4.依研究推論作為贊助對象挑選方法，從20歲以下男女職業前100名之後一級101~200名選手中，挑選男女選手5人（男性2人、女性3人）實證比較，歷經約一年半之賽事都可以達到職業前100名。5.本研究可提供經紀公司、各國網球協會、球具廠商及贊助商，作為挑選選手贊助的重要參考。
