However ... the humanoid characters in the Star Wars universe are never presented as having extra-human abilities ... and mere training as a Jedi does not seem feasible to change physiology to a degree that enables a man to jump 100 feet. Unless they do it with the Force (in which case they could simply levitate), they would need entirely different body structures and muscle configurations to make such leaps with the power of their legs.
To me, this is even more absurd than the telekenisis ... which at least is done with the mind or spirit, and no limits have been illustrated in the movies as to how far a Jedi's mind or spirit may be developed. But to simply assume that they have superhuman abilities, or frelling X-Ray vision for that matter, seems FAKE on its face when no explanation is given for why Jedi can defy the existing physics presented quite clearly to the audience.
And the audience is not doing a scientific analysis when they see an improbable Jedi Jump; they are merely using their eyes and minds to instantly assess what looks "right" for familiar humanity in a physical sense.
(If Luke and Obi-Wan are not human for all intents and purposes, that is nowhere indicated in Star Wars.)
