The United States is a sports-loving nation. Sports in America take various forms: organized competitive struggles, athletic games, hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year.

Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall.

Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It’s not the same as European football or soccer. In American football there are 11 players as well on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. It is still played by almost every college and university in the country.

Basketball is the winner sport in American schools and colleges. Like football, basketball originated in the US, many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. And the famous NBA games are considered the best of this game.

Other sports attracting a great many people include wrestling, boxing and horse racing. Although horse-racing fans call themselves sportsmen, the exactness of the term is questionable, as only the jockeys who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do not come primarily to see the horses race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.
