Participation

Gender participation

Female participation in sports continues to rise alongside the opportunity for involvement and the value of sports for child development and physical fitness. Despite gains during the last three decades, a gap persists in the enrollment figures between male and female players. Female players account for 39% of the total participation in US interscholastic athletics. Gender balance has been accelerating from a 32% increase in 1973–74 to a 63% increase in 1994–95.

Youth participation

Youth sports present children with opportunities for fun, socialization, forming peer relationships, physical fitness, and athletic scholarships. Activists for education and the war on drugs encourage youth sports as a means to increase educational participation and to fight the illegal drug trade. According to the Center for Injury Research and Policy at Nationwide Children's Hospital, the biggest risk for youth sports is death or serious injury including concussion. These risks come from running, basketball, football, volleyball, soccer, gymnastics, and ice hockey.

Disabled participation

Disabled sports also adaptive sports or parasports, are sports played by persons with a disability, including physical and intellectual disabilities. As many of these based on existing sports modified to meet the needs of persons with a disability, they are sometimes referred to as adapted sports. However, not all disabled sports are adapted; several sports that have been specifically created for persons with a disability have no equivalent in able-bodied sports.

Spectator involvement

The competition element of sport, along with the aesthetic appeal of some sports, result in the popularity of people attending to watch sport being played. This has led to the specific phenomenon of spectator sport.

Both amateur and professional sports attract spectators, both in person at the sport venue, and through broadcast mediums including radio, television and internet broadcast. Both attendance in person and viewing remotely can incur a sometimes substantial charge, such as an entrance ticket, or pay-per-view television broadcast.

It is common for popular sports to attract large broadcast audiences, leading to rival broadcasters bidding large amounts of money for the rights to show certain fixtures. The football World Cup attracts a global television audience of hundreds of millions; the 2006 final alone attracted an estimated worldwide audience of well over 700 million and the 2011 Cricket World Cup Final attracted an estimated audience of 135 million in India alone .

In the United States, the championship game of the NFL, the Super Bowl, has become one of the most watched television broadcasts of the year. Super Bowl Sunday is a de facto national holiday in America; the viewership being so great that in 2015, advertising space was reported as being sold at $4.5m for a 30-second slot.
