阻擋 (Obstruct) ITTF 2001-2004

ITTF 2.5.8 A player obstructs the ball if he, or anything he wears or carries, touches it in play when it is above or travelling towards the playing surface and has not passed beyond his end line, not having touched his court since last being struck by his opponent.
ITTF 2.5.8 自他的對手擊球後, 球尚未碰觸他的場地, 尚未越他的端線, 且正在檯面上方或正朝向檯面方向前進時, 若他本身,或他所穿帶的任何物品碰觸到球, 稱為阻擋. (Dr.Wu 翻譯)

澳洲的國際裁判 Steven Lee 解說如下 : (2004-12-25)
阻擋的定義於此很清楚說明應包含兩個條件:
1. above or travelling towards the playing surface (在檯面上方或朝向檯面方向前進) - 此新加部份為重點所在
2. and has not passed beyond his end line (未越過其端線)
example of touch ball

ABC 三情況均未越過端線, 所以要視乎第一個條件而作出判斷, 故此:
A 是阻擋. 因球是朝向檯面方向前進.
B 不是阻擋.因球並不是朝向檯面方向前進.
C 不是阻擋. 因球雖未越過端線, 但已飛越過檯面, 並不再是朝向檯面方向前進.
