He was a water polo player of Russia. He was part of the Russian team at the 2015 World Aquatics Championships.

Timakov was in Bulgaria for pre-season training with his club Sintez Kazan when he “died suddenly” on Sunday, the Russian Water Polo Federation says.

Timakov was swimming during a training session when he began to drown, his teammate Ivan Nagaev told Russian agency Ves Sport.

Players hauled Timakov out of the water and a doctor provided first aid, but Timakov died on the way to hospital, Nagaev said, adding that he believed Timakov had suffered a heart attack.
