Most intresting facts are:
Every school in Cuba participates in the Junior Olympic Program established in 1963. However many of the standard secondary schools only compete in the sports for which they have teams, for instance most of them do not have pools. The competition usually commences in July. The games have a traditional ladder system where first local schools compete, then the district winners will compete and finally the regional winners will compete. However for team sports, the winning teams will move on, but the best players from all of the losing teams will form a new team and also move on. This way no single great player will be tossed out because of a bad team. As of 1978 the Cuban Junior Olympics involved 20 sports: Chess, Weightlifting, Athletics, Tennis, Football, Table Tennis, Basketball, Modern Gymnastics, Gymnastics, Synchronized Swimming, Swimming, Diving, Volleyball, Water Polo, Cycling, Fencing, Judo, Roller derby, Roller hockey, Pistol Shooting, Baseball and Wrestling.
Cuba’s new sports program also began to pay for itself when many of the best players were allowed to retire early and take up position on teams in other countries. These other countries wanted to hire them because of Cuba’s fantastic success in training winning athletes. These players would earn a large salary, and about 80% of it would go directly to the Cuban government. The players would then pocket the other 20%, which was more than what the average Cuban in Cuba was earning. It is worthy to note that Castro abolished professional sport in Cuba in the beginning of the Revolution. What this meant was that all leagues and teams are considered amateur.
And this is probably the last time I spend my time explaining you something, since I expect you to tell me that I'm wrong once again.
