時間與空間對合球投籃表現的影響

Abstract

摘要 合球比賽規則自2009年起加入25秒進攻時間限制，但在合球領域中，尚未見探討進攻時間與投籃表現之關係。目的：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，利用Simi Scout影片分析應用程式標記相關內容，以描述性統計、群聚分析、卡方獨立性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，進攻時間為非常態分布，進攻剩餘時間以群聚分析可分為0~10秒、11~17秒及18~25秒三組。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0~10秒時少於11~17秒與18~25秒；在投籃區域方面，投籃次數以前場最多，後場第二，膠囊區最少；命中率在膠囊區高於前場與後場；進球次數方面，前場高於膠囊區。傳球策略與投籃表現有關係，以內傳內的策略較易形成助攻。結論：時間與空間的因素會影響合球投籃表現。未來可將進攻分為三個不同時間進行更多變項的比較，並將動態投籃與靜態投籃分別記錄。

The korfball game has added a rule of 25-second attack time limit since 2009, but few researches have examined the relation between the attack time and shooting performance. The purpose of the study was to explore how the attack time and shooting area affect the korfball shooting performance. Methods: Twenty korfball games of the 2017 World Games were analyzed for the study. The game videos were downloaded through IKF website, and the SIMI Scout software was used for notational analysis. Results: 2017 World Games Korfball average attack time was 8.66 seconds. The attack time was not normally distributed. Remaining attack times were clustered into 3 groups. The results of two-way repeated measure ANOVA showed that there was the least number of shots, number of goals and goal rate for the 0~10 seconds remaining attack time group than the other 2 groups. For the shooting area, the front court had the g number of shots, the back court came next, and the capsule area had the least number of shots. More goals were from the front court than the capsule area, and the capsule area had the highest goal rate. Shooting performance was associated with passing strategies in that capsule to capsule strategy was highly associated with assist. Conclusion: Time and space both play important roles in korfball shooting performance. Future studies may use 3-group attack time as a basis to analyze more performance variables, and analyze the static shots and dynamicshots separately.
