Canada's Rosie MacLennan, the 2012 and 2016 Olympic champion in the women's contest, will again be a contender in Tokyo. She took third at the 2019 World Championships behind two relative newcomers.  

Silver medalist Bryony Page (GBR) and bronze medalist Li Dan (CHN) are also vying to make their respective teams. Nicole Ahsinger, Team USA's qualifier in 2016, is still active.

On the men's side, 2016 gold medalist Uladzislau Hancharou is still competing, but missed out on the final at the last world championships. Rio bronze medalist Gao Lei is now the reigning world champion and will lead China's quest to win two trampoline medals for a fourth straight Olympics. Dong Dong -- Gao's teammate who's already taken gold, silver and bronze at prior Olympics -- will be in the hunt for a fourth medal. 

All of the Rio medalists could return. Logan Dooley, who qualified for the U.S. at the last two Olympics, has moved into coaching. 

Japan is looking for its first Olympic medal in trampoline and should have a good shot at it with both Hikaru Mori and Chisato Doihata competing on the women's side. Mori is the reigning world champion and Doihata the runner-up. 

For the men's contest, 2019 Worlds individual silver medalist Ivan Litvinovich, who represents Belarus, will be competing in his first Olympics.
