Would one run faster without arms?

  Doubt it. Arms are used for counterbalancing the legs while running, and without arms you won’t be able to use your legs as vigorously. Otherwise the torque would cause you to turn around.

    I have seen claims that this isn’t actually true, swinging our arms to counterbalance the legs is less efficient than just keeping them in place.

    Where did I see this claim? Why, it was in this peer-reviewed scientific paper: youtu.be/-QW25fJ34nA , where by “peer-reviewed” I mean filmed with a live studio audience, and by “scientific paper” I mean segment of a TV panel show.

    So uhhh yeah I’m not buying it but I can’t be bothered to check their sources.

      While I do enjoy Windows (And TIL that Bill Baley is good at running backwards… I hadn’t seen that episode), I take some of their facts with a grain of salt, as it’s primarily an entertainment show. They do tend to oversimplify and miss some nuance from time to time.

  Hmm… less drag and less mass for sure. But also a loss of balancing. In a medium such as air, I don’t think the losses would ever overcome the advantages

  Surprised nobody has mentioned this yet, but the Paralympics may bear you out to some extent. In a lot of events their finish times are similar to normal Olympians, suggesting the reduced weight burden compensates significantly for reduced physical ability.

  (It’s not super clear cut, because apples, oranges, and bouncy prosthetics).

    That was abridge my first thought, although i hadn’t checked Paralympics times

  Well, considering you always run faster with a knife, obviously not, because then you couldn’t hold one.

  Doing research for your planned war against the amputees??? I see right through you

    First the legs now the arms 😂

    I honestly hadn’t noticed it myself lmao

  Additional weight makes it harder to accelerate, but once you’re up to a steady speed it doesn’t make so much difference.

  On the other hand, using your arms as counterweights makes it possible to transfer more force from your foot to the ground with each step.

    once you’re up to a steady speed it doesn’t make so much difference.

    [Citation needed]. You’re still fighting gravity so being lighter makes each step easier. There is also less air drag (but I don’t know how much difference this makes).

      You do have more momentum to counteract the drag, though. I wonder if the decreased mass would be offset by the decreased surface area.

  one would certainly fall easier

  It depends on how big your arms are. I bet you can run around with a pistol but not with heavy guns…
