walking to work has its benefits; like being able to let your mind wander rather than expending energy thinking about traffic. speaking of energy, somehow i got on the random topic of energy usage while walking. so here’s my random scientific question of the day.
to maintain a set walking speed of say 3km/h:
does the momentum generated by swinging your arms while you walk reduce the energy expenditure of the legs enough such that your total energy expended is less than if your hands were in your pockets and your legs had to make up for the lack of forward momentum generated by swinging arms.
something to ponder. if you actually know the answer please hit me up on twitter and tell me.
