A Critique of One Study of Pose Running Technique - Part II

A couple of months ago a wrote a critique of a widely quoted study on Pose Running Technique - A Critique of One Study of Pose Running Technique in which my basic complaints were that the study was very poorly designed, and that it is clear that many of the people who are quoting this study have not read it, or if they did read it, they certainly didn't understand it.

I asked Tracy Peal, who is a highly regarded Pose Coach, to comment on my critique. The comments he made were very interesting, so I thought I would share them; with Tracy's permission of course.

You were right to challenge this ridiculously crafted study. You made great points, but this study is wrong on so many levels:
1.  First, the assumption that Pose is “drastically altering” your running form is a crock. It is drastically altering your thoughts-processes during your run. Pose is actually a “shaving-down” of the unnecessary aspects of most people’s stride. Despite this, everyone (good or bad) has to get to the “pose” of running – that position where both.
Feet are under your COM and falling is about to occur. Pose realizes that since this is the moment when movement occurs (in running), and anything prior to this doesn’t assist in forward propulsion, and then get to this position as soon as possible.

2.  Stride length may “look” shorter (and probably measured that way on novices) because of their inability to fall forward in a timely fashion. No fall=no movement=choppy stride. Yes, Pose is taught to restrict your stride, but it’s the falling that accounts for stride length. Vertical oscillation, from an absence of heel-striking, would be reduced

3.  The increase in VO2 consumption is an easy process I alluded to earlier: a lack of proper falling, which would be enhanced on a treadmill. Therefore, it seems like constantly pulling (on full body weight, no less) instead of what it should be: a passive rebound from the low vertical position that coincides with a foot release from support causing a forward fall into the next support. Without question, the subjects and coaches didn’t understand it to this degree.

The overall issue is that no one believes anything unless it can be validated. I would argue, that there are many things that happen in this world of ours that we accept without fully understanding the how and why.
