in contrast to the older format, par terre now only occurs as a result of a takedown/throw or when a wrestler commits an infraction (eg: passivity). Before each match, each wrestler's name is called, and the wrestler takes his place at the corner of the mat assigned to his color. The referee then calls them to his side at the center of the mat, shakes hands with them, inspects their apparel, and checks for any perspiration, oily or greasy substances, and any other infractions. The two wrestlers then greet each other, shake hands, and the referee blows his whistle to start the period. Upon conclusion of the match, the referee stands at the center of the mat facing the officials' table. Both wrestlers then shake hands, and stand on either side of the referee to await the decision. The referee then proclaims the winner by raising the winner's hand with each wrestler then shaking hands with the referee and his opponent's coach. Old format Prior to recent rule changes, a wrestler wins the match when he has won the majority of periods. For example, if one competitor were to win the first period 1-0 and the second period 1-0, the match would be over. However, if the other competitor were to win the second period, then a third and deciding period would result. Only a fall, injury default, or disqualification terminates the match; all other modes of victory result only in period termination. One side effect of this format is that it is possible for the losing wrestler to outscore the winner. For example, periods may be scored 3-2, 0-4, 1-0, leading to a total score of 4-6 but a win for the wrestler scoring fewer points. This format was changed Each Greco-Roman period is broken up into a phase for wrestling from the neutral position and a maximum of two par terre (ground wrestling) phases. During the wrestling phase from the neutral position, both wrestlers compete for takedowns and points for 60 seconds as usual. At the end of the first minute, in general, the wrestler who has scored the most points will receive the advantage in an Olympic lift from an open par terre position on the other wrestler. This position is known as "par terre". If neither wrestler at this point has any points, the referee will toss a colored disk, with a red-colored side and a
