Horse polo or simply called polo, is a contact sport played on horseback. There are two types of horse polo: field polo which is played using a solid plastic sphere ball, and then there’s the arena polo which is played with a small air-filled ball, which is similar to a soccer ball. Two teams can play with four members each. The team members can be a mix of male and female. The polo equipment are equestrian helmet, colored shirt, riding boots, and white trousers. Optional equipment are kneepads, face mask, whip, and gloves. The main objective of the game is to score goals against the opposing team. Using a mallet, the players can score a goal by driving a small wooden ball into the opponent’s goal. The traditional polo is played at speed on a field with measures up to 300 yards. The modern polo game lasts about two hours and is divided into periods which are called chukkas, which is sometimes called chukkers.
