Synchronised swimming is very popular in many countries of the world. More than a century ago it was known as water ballet, but since 2017 it has been called artistic swimming. The Russian team is one of the best teams in synchronised (artistic) swimming in the world. The Russian athletes won the gold medals at the 2016 Summer Olympics in Rio de Janeiro. Their names are Vlada Chigireva, Natalia Ishchenko, Svetlana Kolesnichenko, Aleksandra Patskevich, Svetlana Romashina, Alla Shishkina, Maria Shurochkina, Elena Prokofyeva and Gelena Topilina.
