Sports in Russia
Sport is as old as the humanity itself. Millions

become strong and to stay in good shape. It makes
them more organized and disciplined in their daily
activities. It makes for a healthy mind in a healthy
body. Sport helps people to keep in good health.
Many sports are popular in Russia. They are ice
hockey, football (soccer), weight-lifting, track and
field, tennis, basketball, volleyball, boxing, figure-
skating, cross-country skiing, swimming, judo,
shooting and so on. Sport is divided into profes-
sional and amateur in our country. There are many
different professional sport societes and clubs in
Russia. They take part in different international
competitions and are known all over the world,
A great number of world records have been set by
Russian sportmen: gymnasts, weightlifters, tennis
players, swimmers, figure skaters, runners, high

world championships and the Olympic Games and
always win a lot of gold, silver and bronze med-

country. They attract large numbers of fans. Most
of the important games we can watch on TV.

cises every day. We all need to exercise. You can
choose sports and games for any season for
any taste.
