Swing the Right Way on Walking
The Guardian reports a study about how the swing of arms affects our walking. According to the researchers in Delft University in Netherlands, swinging arms exert alternating torques on the body, opposite to the ones created by the swinging of the legs.
Normally we walk by swing our arms in opposite direction to the legs. It turns out that there’s a reason behind the way of our walking. If you keep your arms still beside you, it would take 12% more energy than swinging normally. If you swing the arm and the leg on one side together, it uses 26% more energy to keep our body on course. You can watch the video at The Guardian website.
Does that mean that if you want to lost weight by walking you should do that clumsy anti-swing walk?😕
