Alexander Tkachev

At the 2000 Summer Olympics in Sydney, Tkachev transferred his Russian citizenship status to compete for the Kyrgyzstan squad, swimming only in two events. He achieved a FINA B-standard entry time of 2:21.90 from the Russian National Championships in Moscow. In the 200 m breaststroke, Tkachev failed to reach the top 8 final, as he finished his semifinal run with a time of 2:16.90. Earlier in the prelims, he made a surprise packet with a fifteenth-place time of 2:15.63, a Kyrgyzstan record, from a small field of five swimmers in heat two. Three days later, Tkachev teamed up with fellow Russian imports Aleksandr Shilin, Konstantin Ushkov, and Sergey Ashihmin in the 4×100 m medley relay. Swimming the breaststroke leg in heat one, Tkachev recorded a split of 1:03.69, a slowest in the field, but a diverse Kyrgyzstan team settled for seventh place and nineteenth overall in a final time of 3:46.70.

Two years later, at the 1997 Summer Universiade in Messina, Italy, Tkachev earned his second career silver in the sprint breaststroke (1:02.77), handing an entire medal haul for Russia with a one–two finish, alongside Stanislav Lopukhov.

Tkachev established his swimming history, as a member of the Russian squad, at the 1995 Summer Universiade in Fukuoka, Japan, where he captured two swimming medals: a gold in the 200 m breaststroke (2:14.69), and silver in the 100 m breaststroke (1:03.38, narrowly lost to host nation's Akira Hayashi by more than half a second). On that same year, he helped the Russians capture a bronze medal in the 4×100 m medley relay at the FINA Short Course World Championships in Rio de Janeiro, Brazil.

Aleksandr Tkachev (Russian: Александр Ткачев ; born November 11, 1972) is a Russian-born Kyrgyz former swimmer, who specialized in breaststroke events. He collected a total of three medals, one gold and two silver, at the Universiade (1995 and 1997), and later represented his adopted nation Kyrgyzstan at the 2000 Summer Olympics.
