Sports originating in the United States

Female bodybuilding is the female component of competitive bodybuilding. It began in the late 1970s when women began to take part in bodybuilding competitions

Volleyball is a team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since Tokyo 1964.

Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball (approximately 9.4 inches (24 cm) in diameter) through the defender's hoop (a basket 18 inches (46 cm) in diameter mounted 10 feet (3.048 m) high to a backboard at each end of the court, while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.

American football, referred to as football in the United States and Canada and also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.

Baseball is a bat-and-ball game played between two opposing teams who take turns batting and fielding. The game proceeds when a player on the fielding team, called the pitcher, throws a ball which a player on the batting team tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called "runs". The objective of the defensive team (fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The team that scores the most runs by the end of the game is the winner.

Skateboarding is an action sport which involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding will be represented at the 2020 Summer Olympics in Tokyo.

Surfing is a surface water sport in which the wave rider, referred to as a surfer, rides on the forward or face of a moving wave, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or rivers in the form of a standing wave or tidal bore. However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools.

Stock car racing is a form of automobile racing found mainly and most prominently in the United States and Canada, with New Zealand, Australia, Mexico, Great Britain and Brazil also having forms of stock car auto racing. Traditionally, races are run on oval tracks measuring approximately 0.25 to 2.66 miles (0.4 to 4.3 kilometers). The world's largest governing body for stock car racing is the American NASCAR, and its NASCAR Cup Series is the premier top level series of professional stock car racing. Top level races typically range between 200 to 600 miles (322 to 966 km) in length. The cars were originally production models (hence, "stock"), but are now highly modified.

Motorcycle speedway, usually referred to as speedway, is a motorcycle sport involving four and sometimes up to six riders competing over four anti-clockwise laps of an oval circuit. The motorcycles are specialist machines which use only one gear and have no brakes; racing takes place on a flat oval track usually consisting of dirt, loosely packed shale, or crushed rock (mostly used in Australia and New Zealand). Competitors use this surface to slide their machines sideways, powersliding or broadsiding into the bends. On the straight sections of the track the motorcycles reach speeds of up to 70 miles per hour (110 km/h).

Softball is a game similar to baseball played with a larger ball (11 to 12 in. circumference) on a field that has base lengths of 60 feet, a pitcher's mound that ranges from 35–43 feet away from home plate, and a homerun fence that is 220 feet away from home plate. It was invented in 1887 in Chicago, Illinois, United States as an indoor game. The game moves at a faster pace than traditional baseball. There is less time for the base runner to get to first while the opponent fields the ball; yet, the fielder has less time to field the ball while the opponent is running down to first base. The name "softball" was given to the game in 1932, because the ball used to be soft; however, in modern-day usage, the balls are hard.
