Portugal has two trampoline gymnasts competing in the Olympics. At the Olympic Test Event in Rio de Janeiro, Diogo Abreu and two-time Olympian Ana Rente secured their Olympic places in the men's and women's competitions, respectively. Portugal has qualified six judokas at the Games in each of the following weight classes: +100 kg, -66 kg, +65 kg, -53 kg, +52 kg, and -47 kg. Gymnastics has been a popular sport in Portugal since it was introduced by the Portuguese in 1948. The country's top athletes have won multiple gold medals in the past, with many more medals available in all categories. In fact, Portugal is one of the most successful nations in trampoline sports with eight overall medals (three gold, three silver, and two bronze). Portugal's first female gymnast was married woman Ana Rita Pereira who competed at the 1952 Helsinki Olympics. She had several achievements during her career including winning the silver medal in the vault event. After her retirement from athletics, Pereira started practicing trampoline and became one of the world's leading experts in this sport. In 1995, she was appointed as the national team coordinator and led them to victory at the World Championships that year. She also helped Portugal win its first ever Olympic medal when Luana Oliveira took home the silver in the women's individual trampoline event at the 2004 Athens Games.
