Olympic Disciplines - Olympic history will be made at Rio in 2016, when rugby sevens makes its debut appearance at an Olympic Games.
Sevens is the fast-paced, shortened form of the game of rugby played by seven-a-side teams.
The fast, free-flowing nature of the game, passionate spectators and festival atmosphere that are associated with a sevens tournament, along with its growing global broadcast audience and social media following, will make it an exciting addition to the Olympic schedule.
The New Zealand men's and women's rugby sevens teams will be contenders for medals at the Rio Olympics, but they do not hold the favouritism they once had.
Competition at Rio
Twelve men's teams and 12 women's teams will compete at Rio. Both the men's and women's competitions will be held at the Deodoro Stadium:
Women's competition: 6-8 August
Men's competition: 9-11 August
Semi-finals and final take place on the last day of the respective competitions.
Games consist of two halves of 7 minutes, with a 1 minute half-time break. The final will be played over two halves of 10 minutes each, with a half-time break of 2 minutes.
The Stars of Rugby Sevens
While New Zealand's women's and men's sides dominated their respective global competitions initially, sevens has become extremely competitive as its inclusion in the Olympic Games encourages more countries to invest in the game.
The New Zealand Women's Sevens team claimed the first three World Series titles since its introduction in 2012, however this year they finished second behind pacesetters Australia.
Australia are the top women's seeds, ahead of New Zealand, Canada and the United States.
The gap has fast closed on the New Zealand's men's team
Since the world series started in the 1999-2000 season, the New Zealand men have won the World Series 12 times, the last was in 2014.
Fiji are seeded number one in the men's competition ahead of South Africa, New Zealand and the United States.
