Shoulder Rotation and Stride Length

[pinoyathletics]

From the authors of the controversial 'Why Should I drag my toe article?", Coach Adarian Barr and 400m runner Allyson Bodenbach comes another article this time its on Shoulder rotation.

A friend of mind told me in the gym how Alyson Felix and Usain Bolt where applying shoulder rotation. And he said it felt stupid when he experiminted with this while walking but he seemed to cover more ground using less energy.
