I remember myself playing the zazen (aka the creepy ass candle game) Minigame on "Wii Fit Plus" where you where simply sat down with your legs crossed on top of the "Wii Balance Board" and just focus on the candle or whatever, basically meditating with footstep sounds on the background occasionally which can really scare the shit out of you and therefore make you move slightly, which makes the candle flame move, which makes a voice say "CUT" incredibly loudly, and I think that the scariest most unexpected jumpscare are in story of "exergaming" (although now that I think of it it's probably the only Jumpscare in a videogame from the "exergaming" genre) maybe in every videogame ever!
