Hortencia played in the Atlanta Games despite giving birth to Joao just five months earlier. Then 36, she is pictured introducing baby Joao (and his nanny) to basketball during a training session ahead of the 1996 Olympics.

Fast forward more than a decade, and Joao -- 14 in this photo -- is pictured with his mother and father (businessman and horse breeder Jose Victor Oliva). Joao says he has his mother's sporting nature, but inherited his father's passion for horses.

Luiza Almeida is another Brazilian dressage hope for 2016. She was just 16 when she made her Olympic debut at Beijing 2008 (pictured), becoming the youngest equestrian athlete in the history of the Games.

Pessoa won the Athens 2004 Olympic showjumping title, but only once Irish rider Cian O'Connor had been disqualified -- months after the event -- following the revelation that his horse had tested positive for a prohibited substance. Here Pessoa receives the gold medal, at last, a year later in front of Rio's Sugarloaf Mountain.
