不同等級韻律體操選手難度的起始評分、難度的最後得分與難度得分落差之分析－以2007年世界韻律體操錦標賽為例

韻律體操中，難度的起始評分是教練常遇到問題，過去大多依據經驗，未有客觀的數據提供參考，針對不同等級的選手是否應該要有不同的難度設定依據也是目前未解的問題。本研究將針對不同等級的韻律體操選手進行難度起始評分、最後得分與得分落差進行相關性分析並比較不同等級選手的差異。本研究針對2007年世界韻律體操錦標賽預賽的前48名選手進行分析，排名前24名列為優秀選手，其餘為次優秀選手。以Pearson積差相關(α=.05)進行難度起始評分、最後得分與得分落差相關性分析並比較不同等級選手的差異。結果顯示，對所有項目（繩、環、帶、棒），優秀選手的難度起始評分數與最後得分數顯著高於次優秀選手；而得分落差方面，僅棒與帶的項目中，次優秀選手的得分落差顯著高於優秀選手；優秀與次優秀選手的兩項得分成顯著正相關；但起始評分與得分落差僅次優秀選手組達顯著正相關。此顯示不同等級選手難度的起始評分、難度的最後得分與難度得分落差有所不同，次優秀選手難度的起始評分越高對於難度得分落差來說越大。因此，針對次優秀等級的選手，應考量以較低但合理之難度的起始評分標準，以降低難度得分落差及避免損失難度的起始評分。

Pre-setting score of difficulty, set by a rhythmic gymnastics coach, was usually determined by the experience of coaching. Less objective and useful data was provided for the reference of setting the score for players of different classes. Forty-eight players were divided into elite and sub-elite groups equally. Those who were qualified for the 2008 Olympic Game were classed as elite while the others were classed as sub-elite. Pearson correlation was used to analyze the correlation between pre-setting score, final score and score difference. The difference of the mentioned parameters between elite and sub-elite groups was also compared. For rope, hoop, clubs and ribbon, pre-setting score and final score were significantly higher in elite than in sub-elite players. For clubs and ribbon, the score difference was significantly larger in sub-elite than in elite players. Pre-setting score was significantly positively associated with the final score in both groups, whereas pre-setting score significantly positively associated with the final score only in sub-elite group. We concluded that players of different classes had different pre-setting score, final score and score difference of difficulty. The higher the pre-setting score, the larger the score difference performed in sub-elite group. For sub-elite players, reducing the pre-setting score to a reasonable range is suggested.
