So, does the angle your foot strikes the ground really matter? With all the talk about minimalistic training and striking under the body being less stress on the human frame and more efficient, you would think so. Here is one study that seems to support that premise.
from the studies conclusion: “Our results indicate that individuals with a larger knee angle (i.e., greater extension) 50 ms prior to initial contact (IC) experience a higher ROL (Rate of loading) during gait and have poorer proprioceptive scores.”
Proprioception, gait kinematics, and rate of loading during walking: are they related? Riskowski JL, Mikesky AE, Bahamonde RE, Alvey TV 3rd, Burr DB.
