目的：本研究以2009年中國大陸跳水冠軍賽暨第十一屆全運會預選賽女子1m跳板項目56位參賽選手爲對象，主要在於探究難度係數與得分之間的關聯程度，並且以比賽的穩定度表現歸類不同的選手群組及提出改善的策略方案。方法：以描述性統計方法分析選手的動作內容及得分之分布情形，再以單因子變異數分析檢定渠等資料彼此之間的關聯程度。結果：中國大陸選手所採用的難度係數集中於2.3-2.6；最有把握之動作爲第1類動作，而較無把握之動作爲第2類及第5類動作。據此，中國大陸倘若欲於國際比賽中順利奪得金牌，選手的穩定度及在第2類及第5類之動作必需再加強，並且其難度係數勢必提高至3.0以上。結論：本研究發現個人單次難度係數與得分之間的相關程度爲一項重要的參數，因此在比賽中爲求高穩定性之表現，選手應慎選每一次跳水的難度係數及其動作。另外，在相關之國際或重要的比賽之後，建議可利用選手穩定度表現散佈圖之分析，爲選手提出改善其穩定度之策略方案，以利在往後比賽中優異成績之達成。

Purpose: This study aimed at analyzing the diving content, performance records and their association relationship of all the 56 players participated in Women 1M SB (spring board diving) of the China Diving Champion Tournament and 11(superscript th) National Sports Game in 2009, and also proposed strategic plans for improvement to players who had different performance from others. Methods: The descriptive statistical method and one-way ANOVA were used to analyze all the data. Results: The difficulty coefficients adopted by players focused between 2.3-2.6. The most selfconfident diving action was the 1(superscript st) difficulty class, while the worse were the 2(superscript nd) and 5(superscript th) difficulty classes. The promotion of difficulty coefficient up to and over 3.0 and the enhancement of diving action on the 2(superscript nd) and 5(superscript th) difficulty classes would be the premise of obtaining champion. Conclusion: The Pearson correlation of diving difficulty coefficient and score was found to be an important parameter, and the scatter chart of player performance was also found to be a tool for analyzing stability of player. Both could be used to propose the strategic plans to players for future improvements.
