It's AumSum Time.
Why do we Swing our Arms while Walking?
Coz everybody wants to become Michael Jackson.
Naahhh.
When we walk, we usually take a step and swing the opposite arm forward.
Why we do this, is something scientists are still trying to figure out.
However, as per an experiment, it was found that when we swing our arms.
We use 12% less energy as compared to when we hold our arms still.
This means normal arm swinging is not muscle-driven.
But instead they naturally move like a pendulum.
Some experts even suggest arm swinging helps balance our body's rotational motion.
When we put one leg forward, the pelvis twists or rotates sideways.
Thus, forward swing of the opposite hand counterbalances this rotation.
Helping us walk straight.
However, some people believe that.
Arm swinging might be an evolutionary remnant of our ancestors.
Who used all their four limbs to walk.
