Results of Daniel Lieberman Barefoot Running Research

Screencaps from the Nature video, this image shows that initial impact running with a heel-strike registers at around 1.81 x body weight compared to .34 x body weight initial impact running with a forefoot strike. Interestingly, peak bodyweight impact on each curve registers higher with a forefoot strike — around 2.60 x bodyweight running with a forefoot strike compared to 2.30 x body weight with a heel-strike. Note in both running styles here, impact is measured with barefeet.
