合球進攻時間與區域對投籃表現的影響

目的：中華隊在合球世界排名上，長年能夠在前三名的席位，國人對合球的認識卻不比相似的籃球運動，比賽相關的研究亦不如籃球比賽豐富。合球比賽規則自2009年起加入25秒進攻時間限制，且在合球領域中，尚未見探討進攻時間與投籃表現之關係。故本研究欲探討合球比賽進攻時間的使用，及進攻時間與投籃區域對於投籃表現的影響。方法：以2017年世界運動會合球賽事二十場比賽為研究對象，由國際合球協會官方YouTube頻道取得影片，利用Simi Scout影片分析應用程式標記相關內容，再以SPSS統計應用程式分別以描述性統計、相關檢定、群聚分析、卡方適合度檢定及變異數分析等方法進行資料分析。結果：本屆比賽中平均進攻時間為8.66秒，平均進攻時間長短與比賽名次沒有關聯，進攻剩餘時間以群聚分析可分為剩餘0～10秒、剩餘11～17秒及剩餘18～25秒等三組。以進攻剩餘時間及投籃區域進行二因子變異數分析，發現投籃次數、進球次數及命中率在進攻剩餘時間均為剩餘0～10秒時少於另外兩組；投籃區域方面，投籃次數以前場最多，後場第二，膠囊區最少；進球次數方面，前場高於膠囊區；命中率在膠囊區高於前場與後場。結論：不同進攻剩餘時間和不同投籃區域有不同的投籃表現，剩餘秒數較高有較佳投籃表現，膠囊區有最高的命中率。未來可將進攻分為三個不同時間進行比較，進行更多變項的討論。

Purpose: Chinese Taipei has been ranked top three worldwide in korfball in recent years, but this sport is not as well-known as basketball which has similar rules and playing skills as korfball. The research on korfball is also not as much as basketball. The korfball game has added a rule of 25-seconds offensive time limit since 2009, but few researches have examined the relation between the offensive time and game performance. To explore how offensive time were used in korfball games and the effect of the offensive time and the shooting areas on the shooting performance. Methods: Twenty games of the 2017 World Games korfball event were used for analysis. Game videos were downloaded from the YouTube channel of the official website of the International Korfball Federation and the Simi Scout software was used for notational analysis. Descriptive statistics, correlation analysis, cluster analysis, χ^2 test of fitness, and two-way repeated measure analysis of variance (ANOVA) were used for statistical analyses. Results: Average korfball offensive time in 2017 World Games was 8.66 seconds, and there was no correlation between the offensive time and the outcome of the games. Offensive times were clustered into three groups: 0 ~ 10, 11 ~ 17, and 18 ~ 25 seconds remained in the offensive time. The ANOVA results showed that there were fewer number of shots, number of goals, and goal rate in 0 ~ 10 seconds period than the other time remained periods. In addition, the front court had the greatest number of shots and goals whereas the capsule area had the highest goal rate. Conclusions: Offensive time and shooting area had significant influences on the shooting performance in korfball, the shooting performance was higher in the early period of each offense, and the goal rate was higher when shots were taken in the capsule area.
