Скачать или смотреть WHY DO WE SWING OUR ARMS WHEN WE WALK? I SCIENCE EXPLAINED

In this video I talk about one of the behaviors of the human body, the swinging of the arms while walking. University of Michigan scientists measured the energy used by 10 people who walked a number of ways—swinging their arms, holding them to their sides, and so on. They ran similar tests on mechanical models of arms, and they found that the swinging actually has a purpose: It reduces the overall amount of energy it takes to walk.

The study found that people who hold their arms still while walking use twelve percent more metabolic energy than people who swing their arms naturally. If you like this kind of videos, don't forget to subscribe to my channel. #shorts #humanbody #sciencenerd
