Rio 2016: Who are Brazil's best Olympic medal hopes?
Brazil won three golds at each of the past two Olympics and a record 17 medals in London - but who carries their best hopes of a place on the podium at Rio 2016?
Athletics - No outstanding medal chances. Pole vaulter Fabiana Murer has won world outdoor and indoor titles, while long jumper Mauro Vinícius da Silva is a two-time world indoor champion.
Beach volleyball - The men's and women's 2015 world champions are from Brazil. Alison Cerutti and Bruno Schmidt took the men's title, and Barbara Seixas and Agatha Bednarczuk won an all-Brazilian women's final. However, Talita Antunes and Larissa Franca are ranked number one in the world.
Boxing - Lightweight Robson Conceicao has won silver and bronze at the last two World Championships.
Canoe sprint - Isaquias Queiroz dos Santos has won two world titles in the non-Olympic canoe single 500m and added a third gold last year in the canoe double 1000m with Erlon de Souza.
Football - Men and women. Brazil have never won football gold, but Barcelona forward Neymar heads a strong men's squad in Rio.
Gymnastics - Arthur Zanetti is Olympic and former world champion on the rings. Flavia Saraiva, 16, has won multiple gold medals on the beam and floor on the World Cup circuit this year.
Handball - The women's team won a first world title in 2013, although Norway are favourites in Rio.
Judo - Sarah Menezes is an Olympic champion, while 2014 world champion Mayra Aguiar and 2013 world champion Rafaela Silva are also competing.
Modern pentathlon - Yane Marques won bronze at London 2012 and silver and bronze in subsequent World Championships.
Sailing - Robert Scheidt is Brazil's joint most successful Olympian, having won a medal in each of his five Olympics so far, including two gold. He took bronze in star class in London, but is returning to Laser for Rio, where he will be up against British world champion Nick Thompson. Martine Grael and Kahene Kunze won the 2014 world title in the 49erFX, and were silver medallists in 2015.
Swimming - Former 50m freestyle champion Cesar Cielo did not qualify. However, there are medal prospects in the open water events with Allan do Carmo and multiple World Championships medallist Ana Marcela Cunha.
Tennis - Bruno Soares won the Australian Open men's doubles title with Great Britain's Jamie Murray. Soares' expected partner in Rio is recent world number one doubles player Marcelo Melo.
Volleyball - Brazil's women are targeting a third straight gold. The men won silver in 2012 and are the current world number one side.
