Natalia Ishchenko won her fifth gold medal at the world swimming championships on Friday when she combined with Svetlana Romashina to win the synchronised swimming duets free title.
The 25-year-old Ishchenko had already won both solo titles and was also a member, with Romashina, of the gold medal winning free combination team on Thursday. The duo had also won the duets technical title.
Ishchenko has now won 15 world titles in total and her five golds in Shanghai surpasses the four titles she won in Rome in 2009.
The pair scored 98.410 points for their routine, ensuring the Russians continued their domination of the synchronised swimming in Shanghai. They have won all six titles on offer so far with only the team free competition to come on Saturday.
