Sports in space will require new designs rather than porting Earth-based sports to space environments.

“maybe we should say, "What sports would Can we invent sports that would be best served by those gravitational fields and not try to port something from Earth to these other locations.”

Athletes with fast-twitch muscles would be better at sports in a zero-gravity environment because of the need to exert sudden impulses of force.

“the answer to your question, Violetta, is that because everything matters as far as fast twitch and the impulse and then what you do with that impulse after you stop the impulse, fast twitch people are definitely better at space sports than slow twitch people.”

Human-powered flight might be possible on Titan due to its thick atmosphere and low gravity.

“Matthew Ritter, I've heard that due to Titan's thick atmosphere and low gravity that human-powered flight would be possible. We'd also be Superman.”
