The world's biggest women wrestlers are going to be a bit smaller this year, as FILA lowered the highest weight division from 75 kg to 72 kg. In reality, the new weight limit of 158.5 pounds is not really huge for today's women. These athletes will be big and strong, but should also be quick and in outstanding condition.    The reigning World Champion is Edyta Witkowska of Poland, who defeated Ma Bailing of China in the gold medal match. Witkowska has improved each recent season, placing second at the 2000 World Championships and fifth at the 1999 World Championships.    Three-time World Champion Kyoko Hamaguchi of Japan is coming off two disappointing seasons for her, placing fourth at the 2001 World Championships and third at the 2000 World Championships. Her victory at the 2002 Asian Games will give her confidence going into this year's event to return to the top of the podium.    Toccara Montgomery of the United States was the FILA International Woman Wrestler of the Year last season after winning a World silver medal at 149.75 pounds. Montgomery moved up in weight to participate at an Olympic weight class, and has looked very capable at the new division. There is a history of athletes moving up to heavyweight and winning. Canada's Christine Nordhagen-Vierling moved up for two seasons and was the 2000 World Champion, and it was Nordhagen-Vierling that beat Montgomery last year at the 68 kg finals.    Nina Englisch of Germany was the 2001 World bronze medalist, and pinned Hamaguchi in the third-place match. Englisch was a strong second at the 2002 European Championships and should be expected to challenge for the medals.    Russia has developed a new talent at this division, 2002 European Champion Svetlana Martinenko. She was second to Hamaguchi at the 2001 World Cup, and beat Englisch in the European finals.    South Korea has a solid medal hopeful in Kang Min-jung, who won the 2002 Asian Games silver medal and was sixth at the 2001 World Championships. The bronze medalist at the Asian Games was Yana Panova of Kyrgyzstan, who was sixth in the 1999 World Championships.    Canada will be represented by 2002 World University champion Pam Wilson, who scored a minor upset by defeating 2002 Pan American Champion Ohenewa Akuffo for the spot on the Canadian team. Akuffo was 10th at last year's World meet, and Wilson looks to move up higher than that in this year's field. Wilson was third at the 2001 Junior World Championships, which shows she does well at major events.    Yasmily Ramos of Venezuela was a 2002 Pan American silver medalist and placed eighth in the 2001 World Championships. Ukraine should be well represented, either by 2002 European bronze medalist Svetlana Sayenko, or Tetyan Kmarnitska, who was seventh in the 2001 World Championships. Katerina Halova of the Czech Republic was fourth at the 2000 World Championships and could be another athlete with     Xueyan Jiang of China was third in the 2001 World Cup, a solid alternative if World silver medalist Ma Bailing does not enter. The 2002 African champion is Riabi Saida of Tunisia, who hopes to make a name for herself at the World level.    Other athletes to watch include Heidi Martti of Finland, Maider Unda of Spain, Katarzyna Juszcza of Italy, Elvira Barriga of Austria, May Bente Eriksson of Norway and Inga Cecilia Alenius of Sweden.     The big test this year will be for Poland's Witkowska, who will find out just how difficult it can be to defend a World title. She should expect a strong challenge from past champion Hamaguchi of Japan, hard-charging Englisch of Germany and talented young American Montgomery. China's Bailing could also be part of this mix. This weight class has talent and experience, and it will be difficult for a new athlete to break in, but that could be Russia's Martinenko or Korea's Kang. With this kind of firepower, this weight division should be very exciting again this season.    2001 World Championships results   75 kg/165.25 - Gold - Edyta Witkowska (Poland) dec.
