Why do children have so much energy?

Question

Is there a biological/physiological reason why children have so much energy? I was thinking, surely there must be a scientific explanation, and could this be replicated in adult humans?

Answer 1

The energy cost to move a tiny 30 pound body is a small fraction of the energy cost to move a 200 lb adult body. So them bouncing off the walls looks like they have a ton on energy, but in fact you getting off the couch to clean up their mess requires twice as much.
