text: Beach tennis is a game combining elements of tennis and volleyball and played on a beach.
  Overview
  Beach tennis is played in over 50 countries and by more than half a million people, with its greatest popularity occurring in Italy, Brazil and Spain. Beach tennis offers a highly aerobic cardio workout with low impact to the knees and joints because it is played on sand.
  The sport preserves most of the rules and scoring of traditional tennis, though modifications have been made to adapt to movement around the sand court and to the faster pace of the game. As the ball may not touch the ground, the game is played entirely with volleys, which makes for a quicker game than does traditional tennis. Points start with a serve and end when the ball touches the ground, forcing players to dive to reach difficult plays in a similar manner used by volleyball players. The objective is to return the ball with only one hit so that it reaches the opposing side of the net.
  A depressurized tennis ball, which travels more slowly through the air than does a regulation tennis ball, is used for beach tennis to allow for longer rallies. The sport is usually played by two-person teams on a regulation beach-volleyball court with a 5-foot-7-inch-high net.
