Technically ultra-competive environments usually trigger a similar response in the body anyway, just the method of the trigger differs.(music, meditation, rituals, etc)

And the technically technically if someone who had equal or greater amounts of fast twitch muscle fibers compared to Usain Bolt could run faster anyway, Usain Bolt could set a new record probably if say a tiger was chasing him

So what I'm trying to say is your top speed is determined by ratio of fast:slow twitch muscle fibers, the adrenaline determines more how easily you can reach this top speed.
