Comment on Would one run faster without arms?

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.

[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.
