Will an athlete who runs for an hour at moderate pace and is not tired at the end burn more calories than an out of shape person who runs for an hour a way shorter distance but is exhausted at the end?
Assuming both have the same weight and such
What I want to know basically is if your body gets stronger will it need less energy to perform the same amount of work?
In: 1708
You burn ~30% more calories jogging than walking. But that’s about it (i.e if you increase running speed more the increase in calories burnt doesn’t increase as much).
So walking 1km burns less energy than running 1km. Obvs efficiency comes into it as you get fitter your body becomes better at stuff. For example if your leg muscles are initially weak you may be using other muscles to compensate for the weakness.
Edit: here’s a study about it
