the same amount of energy gets burnt whether you're running or walking, it just changes how fast it gets burnt. If you're running, you burn it up more quickly then you would walking.

It's a simple energy and force balance.

Does it say "You burn exactly the same amount of energy walking than you do running"

I bet it doesn't state that walking and running require an identical amount of energy.

I didn't. I said "Around". Ie - not the exact same amount.

"the same amount of energy gets burnt whether you're running or walking"
Which doesn't leave any wiggle room about "around" or "exact"

for a given speed. I can't find the reference though, sorry.

moving one lump of stuff from point a to point b always requires the same amount of energy if all things are equal.
.... I'm confusing myself now.

It's the same as walking up a slope versus stairs. Stairs are apparently more efficient.

Some guy in the states somehow managed to get a PhD out of it a couple of years ago, but it's pretty obvious Newtonian physics. When you walk, you keep your legs mostly straight, and your center of gravity rides along fairly smoothly on top of your legs. In running, you jump from one foot to the other. Each jump raises your center of gravity when you take off, and lowers it when you land because you bend the knee to absorb the shock. This continual rise and fall of our weight requires a tremendous amount of Newtonian force, essentially to work against gravity, on both takeoff and landing, which doesn't happen in walking.
That's before you even get into the biology aspect of efficiency of anaerobic vs aerobic respiration (anaerobic is more common in running and is less efficient) and issues of wind resistance, although that's a function of speed and you are talking about running vs walking at the same speed so you're correct, that doesn't matter)

and purely working from the physics point of view, that is fairly obvious

a difference due to the efficiency of either walking and running. No I get your point about lifting off the ground but I always thought running made more efficient use of momentum than walking.
(, Mon 18 Apr 2011, 10:01, Reply)
so if the running and walking speeds are the same then no, of course it doesn't.

Unless that's a deliberate grammatical error, in which case 'breasts' is my dental hygienist, for she keeps resting them on my shoulder while scraping me.

I thought the apostrophe was indicating that I wanted to know the owner of the breasts about which you were thinking?
