優秀運動員使用營養補充劑的情形受到許多因素的影響，故本研究目的在調查國內女子社會甲組籃球選手使用營養補充劑的種類、頻率、時機以及資訊來源和考量之盛行率。本研究以問卷方式施測，共111位女子籃球選手完成問卷。研究結果顯示選手使用營養補充劑的比率為94.6%，每位選手平均使用4.1 ± 2.2種營養補充劑。在所有種類項目中使用率較高為運動飲料、維生素B群和能量果凍。使用時機部分，選手在運動前較常使用巧克力和維生素B群，在運動中較常使用為運動飲料與能量果凍，在運動後使用率較高的則為高蛋白。使用頻率除了高蛋白為一週三次外，大多數項目的使用為一天一次或偶而使用。在不同球隊、年齡層與是否上過營養課程的選手之營養補充劑使用情形均無明顯不同。選手使用營養補充劑的資訊來源主要為體能訓練員／防護員、教練和父母／親戚，使用營養補充劑的考量以補充營養和獲得能量為主。本研究結論為女子社會甲組籃球選手普遍有使用營養補充劑的情形，而資訊來源主要來自非專業人員，使用考量主要為補充營養和獲得能量；此結果可做為運動相關人員未來進行營養教育之參考。

Consumption of nutritional supplement among elite athletes could be influenced by many factors. The purpose of this study was to investigate the prevalence of nutritional supplements intake among division I female basketball players, and particularly examined the type, frequency, timing, source of information of nutritional supplements and reasons for the supplement intake by the players. A survey with questionnaire was conducted on 111 female basketball players. The result indicated that consumption of the nutritional supplements by the basketball players were about 94.6%, with an average of 4.1 ± 2.2 types of products by each player. The sports drinks, vitamin B complex and energy jellies were found to be the most popular supplements. For the timing of nutritional supplement, data indicated that most often used supplements prior to exercise were the chocolate and vitamin B complex, during exercise were the sports drinks and energy jellies, and after exercise were the protein supplements. The supplements frequency showed that most supplements were used once per a day or irregularly, but the protein supplements were used three times per a week. No significant differences were noticed on the prevalence of supplements use among different teams, age groups and experience of enrolling nutrition education. Furthermore, the source of information was mainly from the strength and conditioning instructors/athletic trainers, coaches as well as families/relatives. The major reasons for supplements intake were nutrients replacement and increasing energy. This study concludes that division I female basketball players were frequent users of nutritional supplement. The source of information was from non-professional members and they used supplements for nutrients replacement and increasing energy. The results of this study could be considered as a reference in the field of sports nutrition.
