How Physical is Water Polo?
Another interesting point is the way water polo rules distinguish between degrees of physical contact. The four rules that deal with contact are: impeding (swimming over someone), pushing, holding and brutality. With the exception of brutality (intentionally striking the opponent), these rules do not apply when an opponent is holding the ball. In other words, they can be tackled. However, impeding and pushing are generally considered minor or ordinary fouls. To hold, sink or pull back an opponent not holding the ball is considered a major foul.
