Dr. Daniel Lieberman from Harvard University has released his second Nature paper concerning human evolution and the way humans run. The latest paper, entitled "Foot strike patterns and collision forces in habitually barefoot versus shod runners", concludes that forefoot or midfoot strike gaits, which are more common when running barefoot or with minimal footwear, may protect runners from impact-related injuries now common to runners.
Dr. Lieberman has launched a Running Barefoot website as well that explains more of his research. There is also a video, released by Nature, that features an interview with Dr. Lieberman and some of his research.
I've been waiting for this research for a long time and can't wait to spend many happy hours reviewing it.
