Apparatus on which Bryony Page won a silver medal in Rio and a bronze medal in Tokyo at the Olympic Games (10)
I believe the answer is:
trampoline
(Other definitions for trampoline that I've seen before include "Sprung gymnastic equipment" , "Trap oilmen (anag.)" , "Bouncy activity here" , "On which bouncers go" , "where pike may count in competition" .)
