本研究目的為瞭解2018、2019年世界競技體操錦標賽臺灣選手動作分值、實施得分(execution score,簡稱E分)表現與標準化實施扣分值(standardized execution deduction value,簡稱SED值)等成績變化與2020年東京奧林匹克運動會團隊參賽資格的關係。研究對象為2018、2019年世界錦標賽(簡稱世錦賽)臺灣男子競技體操選手,影像資料源自2018、2019年兩屆臺灣參賽選手的表現成績,透過獨立樣本t檢定考驗動作分值、E分值及SED值,並以卡方檢定考驗不同級距實施扣分的次數。研究結果顯示:5個項目的動作分值在兩屆比賽中未達顯著差異;2019年世錦賽在6個項目E分值顯著高於2018年世錦賽,SED值顯著低於2018年世錦賽。本研究所得的結論為:臺灣選手在體操5個項目的動作分值使用情況已相當接近;E分的提升與SED值的降低,為臺灣選手獲得夏季奧林匹克運動會(Summer Olympic Games,簡稱奧運會)參賽資格的主要原因;本研究是首次將SED值應用於競技體操的分析,未來還需要更多競賽結果的驗證。
This study aimed to investigate key factors to qualify for the 2020 Summer Olympics men's artistic gymnastics by comparing the effective score, execution score (E score), and the standardized execution deduction value (SED) on each apparatus at the 2018 and 2019 World Artistic Gymnastics Championships. Taiwan's men's gymnastics team qualifies for the 2020 Summer Olympics by winning the 2019 World Artistic Gymnastics Championships. The gymnastics performance of the Taiwan gymnasts, who previously competed at the 2018 and 2019 World Artistic Gymnastics Championships was analyzed in this study. The independent t test was used to compare the effective score and the SED value on 5 apparatus, and the E score on 6 apparatus between the 2018 and 2019 World Artistic Gymnastics Championships. In addition, the Chi-square test was used to compare the execution deduction with 3 levels (≤ 1.5, 1.6-2.0, and ≥ 2.1) between the 2018 and 2019 World Artistic Gymnastics Championships. The results showed that there were no significant differences in the effective score on 5 apparatus between the 2018 and 2019 World Artistic Gymnastics Championships. The E scores on 6 apparatus in the 2019 event were significantly higher than those in the 2018 event. In addition, a smaller percentage of higher execution deduction (≥ 2.1) and a larger percentage of lower execution deduction (≤ 1.5) were observed at the 2019 World Artistic Gymnastics Championships. Finally, the SED values on each apparatus in the 2019 event were significantly lower than those in the 2018 event. We conclude that the major findings of this study were the effective scores of Taiwan gymnasts on 5 apparatus were similar. The improvement from the 2018 to the 2019 World Artistic Gymnastics Championships was primarily through the increase in E score and the decrease in SED value in the 2019 event. This study confirmed that the SED values could be a useful index of gymnastic performance.
