At the end of the day, astronauts still have to work out, right? EMS is just a supplement. It’s nowhere near efficient enough to reshape someone's physique without putting in actual effort. Plus, there are contraindications to consider, and plenty of different EMS variations out there.
It’s not quite 90%; we generally lean toward traditional physical therapy. 🙂 EMS is used when natural muscle innervation is weakened and voluntary contraction can't be achieved—and occasionally when it is intact, though that's rare. But that’s just maintenance, definitely not for making progress.
Finally, someone who actually knows their stuff. 🙂
Steven Ward10, believe me, I’ve spent a significant amount of time working with astronauts, so please don't speak out of turn. If you only knew the kind of workouts they do up there... The problem of zero gravity and maintaining muscle mass in that environment hasn't been solved to this day. Astronauts on long-duration missions have to do hours of intense exercise using resistance bands (because weights are useless without gravity 😛), doing things like rowing and similar movements. Even with all that training, after several months in zero-G, their bodies aren't even strong enough to support themselves when they return to Earth, so they often have to be carried off the spacecraft. EMS has only recently become a minor supplement used as passive exercise—basically, while they're busy doing something else. To claim that astronauts atrophy because of EMS is, frankly, unprofessional. But then again, around here, it’s become common practice to toss science around without any foundation. If someone were to ask about the composition of the soil on Neptune, a hundred armchair experts would jump in to engage in a "scientific" debate. And if the topic happens to be medicine, football, or politics, there's no shortage of self-proclaimed experts. 😛
