But wait, there’s more! You can apply this same technique to walking, allowing you to walk “without any muscular effort”—just coasting along with gravity pushing you forward like some sort of perpetual motion machine. Even better, you can carry heavy loads and walk uphill with no additional effort, all thanks to gravity. So what do you need to do to get these wonderful benefits? The basic gist is that you have to make sure your foot lands below your center of mass, rather than in front of it, so you can preserve the angular momentum generated by gravity when you lean forward. The paper presents the theory with a bunch of equations, then some experimental results showing how well it works. The main bit of experimental data comes from a “49-year-old veteran male runner who had over the years become able to do relatively well on angular momentum-assisted running”—in other wor...
