The Russian team proved most dominant this weekend as they recorded a 14-strong medal haul, including four gold, five silver and five bronze.

China’s annual IJF Grand Prix, which was first held in 2009, was held in Qingdao for the final time this weekend before it moves to Hohhot in Inner Mongolia, in the north of China, from 2017.

Action concluded today with the women’s under-78 kilogram and over-78kg categories, as well as the men’s under-90kg, under-100kg and over-100kg divisions.

World champion Yu won the domestic bragging rights as she defeated compatriot Ma Sisi in the women's over-78kg competition.

Yu extended her head-to-head record to 4-2 over Ma as she made a winning return to action in her first competition since winning bronze at the Rio 2016 Olympic Games, producing a title winning ippon with 90 seconds left on the clock.

One bronze medal was won by 2011 Qingdao Grand Prix bronze medallist Kang Jie of China, while Eun-Ju Lee of South Korea won the second after she defeated China's Xu Xin on shido penalties.

In the only other women's competition today, Rika Takayama of Japan won her first Grand Prix gold medal.

World number 14 Takayama squared off against Zhang Kaili of China in the under-78kg contest, who was contesting her first IJF World Judo Tour final.

The young Japanese fighter wrapped up her opponent on the ground in an osaekomi before inflicting a ude-garami on the left arm of her Chinese foe to secure the win.

The first bronze medal was won by China's Ma Zhenzhao after she beat her 19-year-old compatriot Tian Miao, while the second was won by former Almaty Grand Prix winner Anastasiya Dmitrieva of Russia after she proved too strong for Li Yang of China.

There was further success for Japan in the men's over-100kg category as Yusei Ogawa overpowered Russian Anton Krivobokov to win gold.

Ogawa pinned down the Russian with a mune-gatame, forcing his opponent to tap out after just 18 seconds.

Claiming the first bronze medal in this division was Mongolian Duurenbayar Ulziibayar after he came from behind to beat Lee Po Yen of Chinese Taipei in the closing seconds.

The second bronze medal went to Russian Andrey Volkov, who edged past two-time Grand Prix bronze medallist Kim Kyeongtae of South Korea.

Cementing Russia's place at the top of the medal table was Kirill Denisov after he prevailed in the under-100kg competition to win a debut gold at his new weight.

Denisov gave up his world number 12 ranking at under-90kg to move up a division.

That decision was vindicated today as he beat Tsogtgerel Khutag of Mongolia by ippon after 29 seconds.

In the final competition of this weekend's action, Glasgow European Open winner Max Stewart of Britain turned his number one seed status into gold with the best performance of his blossoming career.

The 23-year-old defeated Mongolia's Altanbagana Gantulga in the under-90kg division and rushed to celebrate with his coach and dad Dennis Stewart, who won bronze at the 1988 Seoul Olympic Games.

"I was always looking for the strangle in the final and I had the perfect chance after my first hold down," said Stewart.

"I am getting used to fighting at these bigger events and I hope for more competitions and more success in 2017.

"My next event will be the British Championships in December."

The first bronze medal was awarded to rank outsider Said Emi Zhambekov of Russia, the world number 133, after he defeated Jaeyong Lee of South Korea.

The second went to another South Korean, Chan Jeon, who overcame Erihemubatu of China.
