Nature Video: The Barefoot Professor
Posted by "GrrlScientist" on January 28, 2010 tags: kinematics, kinetics, running,The Barefoot Professor, exercise physiology, barefoot running, NPG, peer-reviewed research, NATURE, 10.1038/nature08723, streaming video Harvard professor Daniel Lieberman ditched his trainers and started running barefoot. His research shows that barefoot runners, who tend to land on their fore-foot, generate less impact shock than runners in sports shoes who land heel first. This…
