We swing our arms while sprinting and it feels odd not to do it. Does it help with anything?

When we walk we are (subconsciously) always rebalancing out body weight so we don’t fall over like big dolls. Just pick an action figure or barbie doll and try to make it stand on its own. Its a surprising amount of calculating.
You don’t notice this cause you have been doing it for years since you started to walk every day. People who lost a leg and got a prosthetic report that they had to genuinely learn how to walk again as s full adult cause all their instincts are based on a foot/leg that can shift miniscule amounts of weight all the time.
Now when you run you essentially exponentially up the difficulty of this by moving through positions much faster and more rapidly. So your body does the same thing it does when balancing on a wire: get the arms to help out with the rebalancing 🙂
