Arena Polo,.........( Polo )

The enclosed area is much like those used for other equestrian sports 300 by 150 feet (91 by 46 m); the minimum size is 150 by 75 feet (46 by 23 m). Arena polo has more manoeuvering due to space limitations, and uses an air-inflated ball slightly larger than the hard solid ball used in field polo.

The indoor arena polo ball is often leather-covered and air-inflated. It is larger compared to the smaller and harder ball used in outdoor polo. The ball must be not less than 12.5 inches (32 cm) or more than 15 inches (38 cm) in circumference. The weight must be between 170 grams (6.0 oz) and 182 grams (6.4 oz).

In a bounce test from 9 feet (2.7 m) on concrete at 70 °F (21 °C), the rebound should be a minimum of 54 inches (140 cm) and a maximum of 64 inches (160 cm) at the inflation rate specified by the manufacturer.

Some larger, custom-sized indoor balls are also available, such as 40 centimetres (16 in) diameter versions for specific conditions. This provides for a hard and lively ball.

Standard mallets are used, though slightly larger-head arena mallets are an option.
