摘要

本研究目的採次級資料分析，使用Python網路爬蟲技術，蒐集沙灘排球資料庫內全球沙灘排球選手資料，共19,525人；再篩選2008～2016年三屆奧林匹克運動會（簡稱奧運），分析2,336筆男性選手，1,942筆女性選手資料。分析結果發現男女性選手在國際排球總會比賽中累積的獎金多寡與參加站數，與獲選為奧運選手的機率有顯著相關。其次，穩定的合作搭檔也是一個重要因素，在男性選手中，生涯合作過搭檔人數愈少，奧運參賽機會也稍高一些。再者，國際排球總會奪牌次數也是重要影響因子，不論男女選手，在實戰中累積經驗，獲牌次數也影響進入奧運的機會。臺灣近年沙灘排球選手表現，在亞洲前八強中，身高不及其他國家、參與國際賽的經驗亦顯不足，是值得反思未來培訓策略的重要資料。本研究結論是建議藉由目前世界沙灘排球賽制改變的機會，短期在亞洲運動會奪牌，長期則以奧運參賽為目標，透過持續性的大數據分析，針對選材機制、參賽站數等因素，規劃細部策略。

The purpose of this study was to conduct the secondary data analysis along with Python web crawler tool to collect 19,525 beach volleyball players' data from the Beach Volleyball Database. From 3 consecutive Olympic Games (2008, 2012 and 2016), we selected the data of 2,226 male players and 1,942 female players. The results showed that the accumulating prize money earned from the Fédération Internationale de Volleyball (FIVB) tournament and the frequency of competition participation were correlated with the rate to pass the elections as eligible players. Secondly, stable partnership is one of the key factors as well. Among males, less partners during the careers represented higher rates to pass the elections for Olympic Games. In addition, medal counts from the FIVB tournament, which imply experience obtained from competitions, was found as a significant factor to influence the chance to be chosen. We found that among the top eight national teams in Asia, Taiwanese players were shorter than other national players and with less participation in international tournament which can be considered as key improvements in the future trainings and cultivation. Our study advised that by taking the advantage of the competition system change, pursuing victory at the Asian Games should be set as the short term target in order to further striving for good performance at the Olympic Games. This can be achievable through continuous big data analysis focusing on the election system, presence of competitions and other key factors, so the detailed strategies can be formulated accordingly.
