Most of the calories spent not on muscle movement that consumes oxygen, but on warming up the body. That probably also consumes oxygen, but I'm not sure how much.
- nradov 8y agoGenerating energy takes roughly the same amount of oxygen either way regardless of whether you're pedaling a bike or just staying warm in a freezing environment.
- robotresearcher 8y agoWhen working, keeping warm doesn't use additional calories to the work (skiing and sled-pulling), since heat is a biproduct of the work. In fact they are careful not to work too hard so they don't sweat. (Getting wet makes their insulation ineffective, so is very dangerous.)
