Mixed hockey
Mixed hockey is collective name for the sport of field hockey that comprises both men and women on one team. A team will contain eleven players: five will be male, five are female and the goalkeeper can be either sex. Mixed hockey is not associated with ice hockey or street hockey and is played on astroturf or grass. Many countries have extensive club competitions for junior and senior players. Despite the large number of participants—hockey is thought to be the field team sport with the second-largest number of participants worldwide (the first being football)—club hockey is  not a large spectator sport and few players play as full-time professionals. Hockey is a sport played internationally by both males and females, however in some countries, such as the United States, it is predominantly played by females. The England Hockey Board (EHB) is the National Governing Body for hockey in England. Terminology. Field of play. The information below provides a simplified description of the field of play.
