MANY BITTER BATTLES have been fought over table tennis at vegan fitness weeks
(the swedes think they are the best in the sport)
I have not been involved (and am not close enough to likely ever attend VF weeks) but can I join fray with a couple of observations....
China is absolutely dominant. They have over 20 million trained players (out of probably 25-30million in the sport, globally), and their top 1000 players put in probably at least twice the training man hours that the top 1000 from the rest of the world do. All this shows in technical knowledge, match fitness, money, medal statistics, rankings and injuries.
Sweden is a powerhouse of top level European / non-Asian table tennis success, albeit increasingly a historical one compared to what's happening in Germany now, and to an extent, some of the Slavic countries.
Japan's pretty well up there (money, resources, culture and players) although, interestingly, their current star Jun Mizutani is very strongly influenced by German training.
France is relatively strong in Europe and arguably the most creative these days.
Compared to ANY of the above, Korea punch way above their weight in terms of passion for the sport, results per capita and peak levels of match fitness. Currently they have 4 more players than Sweden does in the men's top 20: http://www.ittfranking.com/gen/world/worldM_en.htm
If I have to pick a country to support in table tennis, it will be Australia, Korea then maybe Germany, Austria or Japan ... if I have to pick players to *watch*, it's a very difficult contest between Korea and China (passion, fitness and variety of styles vs technical perfection)... but i I didn't play the game or played a different style, the French and some of the other Europeans would be just as exciting to watch and may edge out Sweden for the creativity factor these days.
I'd love to see another Swedish great in table tennis, they are certainly extremely good, and I can't admire Waldner and Persson enough... but Sweden can't trade on the reputation of a few legends forever.
