Wednesday was a record-breaking day in the pool for an Israeli swimmer as well as many others. Israel's Anya Gostomelsky advanced to the final of the 100 meter backstroke at the World Short Course Swimming Championships in Manchester. Gostomelsky, who will swim for Israel at this summer's Olympics, clocked a new Israeli record time of 58.43 seconds in the semifinal, progressing to Thursday's final from fifth place overall. In Thursday's final, Gostomelsky will be hoping to at least repeat her performance from the last championships in Shanghai in 2006 where she finished fifth in the 100m backstroke. The other Israeli in the competition, Guy Barnea, failed to advance to the final of the men's 100m backstroke on Wednesday, finishing in 13th place overall in a time of 52.63s. In other action, the United States set a world record in the men's 400 freestyle relay. The American team of Ryan Lochte, Bryan Lundquist, Nathan Adrian and Doug Van Wie finished in 3 minutes, 8.44 seconds on Wednesday. Sweden had set the previous mark of 3:09.57 in 2000. As well, the Netherlands set a world record in the women's 800 freestyle relay. The Dutch team of Inge Dekker, Fernke Heemskerk, Marleen Veldhuis and Ranomi Kromowidjojo finished in 7 minutes, 38.90 seconds to eclipse the previous mark. China had set the previous record of 7:46.30 at the 2002 short-course worlds in Moscow. The next three finishers - Britain, Australia and the United States - were also ahead of the old mark. Britain finished in 7:38.96, while Australia finished in 7:39.01 and the United States finished in 7:45.58.
