So! I've been thinking about this one for a while...
If a person walks a mile and then runs that very same mile, and everything else being equal, does that person use up the same amount of joules (calories) for walking and running.
Logic tells me the work needed to travel the distance is equal and therefore the energy used should be the same... But for some reason I suspect there may be more energy burned running. But I don't know where or why.
What say you.
