Bodysurfing is the art and sport of riding a wave without the assistance of any buoyant device such as a surfboard or bodyboard. Bodysurfers often equip themselves with a pair of swimfins that aid propulsion and help the bodysurfer catch, ride and kick out of waves. Some bodysurfers also use a handplane, which helps get your chest out of the water to reduce drag. Some of the best waves for bodysurfing are steep, fast, tubing beachbreak waves that are often unsuitable for boardsurfing; two of the best known are Sandy Beach and Makapuu on the east shore of Oahu in Hawaii. The Wedge, in Newport Beach, California, a ferocious sand-pounding peak wave aptly described by Sports Illustrated in 1971 as "a great big screaming shorebreak," has for decades been bodysurfing's most fearsome and famous break. Other regions with world-class bodysurfing waves include Hossegor (France), Puerto Escondido (Mexico), and Nazaré (Portugal). Distinguished bodysurfers include Buffalo Keaulana and Barry Holt of Hawaii; Californians Bud Browne, Candy Calhoun, Larry Lunbeck, and Mickey Muñoz; Wedge riders Fred Simpson, Terry Wade, and Mark McDonald; and Australians Don McCredie, Tony Hubbard, Max Watt, and Michael Fay. Hawaiian lifeguard Mark Cunningham, a sublimely smooth master at the board-dominated Pipeline, was unanimously regarded as the world's premier bodysurfer from the mid-1970s to the early '90s; nine-time bodyboarding world champion Mike Stewart then become the sport's dominant presence, and was the first to do a barrel roll at Pipeline.

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 in diameter) through the defender's hoop (a basket in diameter mounted 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 or more 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. Players advance the ball by bouncing it while walking or running (dribbling) or by passing it to a teammate, both of which require considerable skill. On offense, players may use a variety of shots—the lay-up, the jump shot, or a dunk; on defense, they may steal the ball from a dribbler, intercept passes, or block shots; either offense or defense may collect a rebound, that is, a missed shot that bounces from rim or backboard. It is a violation to lift or drag one's pivot foot without dribbling the ball, to carry it, or to hold the ball with both hands then resume dribbling. The five players on each side at a time fall into five playing positions: the tallest player is usually the center, the tallest and strongest is the power forward, a slightly shorter but more agile player is the small forward, and the shortest players or the best ball handlers are the shooting guard and the point guard, who implements the coach's game plan by managing the execution of offensive and defensive plays (player positioning). Informally, players may play three-on-three, two-on-two, and one-on-one. Invented in 1891 by Canadian-American gym teacher James Naismith in Springfield, Massachusetts, United States, basketball has evolved to become one of the world's most popular and widely viewed sports. The National Basketball Association (NBA) is the most significant professional basketball league in the world in terms of popularity, salaries, talent, and level of competition. Outside North America, the top clubs from national leagues qualify to continental championships such as the EuroLeague and the Basketball Champions League Americas. The FIBA Basketball World Cup and Men's Olympic Basketball Tournament are the major international events of the sport and attract top national teams from around the world. Each continent hosts regional competitions for national teams, like EuroBasket and FIBA AmeriCup. The FIBA Women's Basketball World Cup and Women's Olympic Basketball Tournament feature top national teams from continental championships. The main North American league is the WNBA (NCAA Women's Division I Basketball Championship is also popular), whereas strongest European clubs participate in the EuroLeague Women.
