There are two styles in modern wrestling: freestyle and greco-roman.
The main difference between these two, is that in the greco-roman style, holds are allowed from the waist up, while in free style holds are allowed on the whole body. Matches in both styles consist of two, three-minute parts, with a 30 second interval.
Each wrestler attempts to win over his adversary, either by holding both shoulders on the ground (fall) long enough to be in control. If someone can pin the opponent to the floor, it automatically ends the match. Wrestlers can also win by taking a ten-point lead (technical superiority) through a variety of holds and moves, or by finishing with more points.
344 athletes will compete in the wrestling event of the Athens 2004 Olympic Games.
