LONDON, Aug 1: China continued their dominant run at the Games on Wednesday with Lu Xiaojun improving his own snatch and total world records in winning the men's -77kg class weightlifting gold before Jioa Liuyan won the women’s 200m butterfly final in record time.

On the fifth day of full action at the Olympics, Lu lifted 175 kilograms in the snatch, bettering his own world mark by 1 kg. He then took 204 kg in his final clean and jerk for a world record total of 379 kg.

Jiao continued the Chinese gold rush when she touched in 2 minutes, 4.06 seconds, 0.12 quicker than countrywoman Liu Zige's time at the 2008 Beijing Games.

Also in the pool, Nathan Adrian of the United States won the men's 100m freestyle gold with Australia's James Magnussen in second and Canada's Brent Hayden in third.

Hungarian Daniel Gyurta won the men's 200m breaststroke gold in a world record time of 2min 07.28sec, breaking the record of 2:07.31 set by Australian Christian Sprenger at the 2009 world championships in Rome.

Japan's Kosuke Kitajima, going for a third straight Olympic title, was shut out of the medals in fourth.

Better news for Japan came when Kohei Uchimura won the Olympic gold medal in the individual all-around gymnastics final, completing a remarkable turnaround four years after letting the title slip through his fingers when he ended up taking silver at the Beijing Olympics.
