This is the exact outcome we want from the conference…collaborations of folks from different fields who are expert communicators of what all this means to the general public. thank you both for taking your time to chat and post the science and your educated opinions.

Great job Chris, congrats on the BQ! If you read Jay Dicharry’s posts,
he confirms what I said to you about footstrike. Other aspects of form
may be more important, and your stride looked good to my eye.

Pete, I wanted to let you know that I BQ’d on Sunday. Finally. I appreciate the time you took to look at my form and the confidence you gave me that it was very much “good enough” for now. I was stressing, but you helped me relax.

Thanks,
Chris Korn

I’d love to spend an afternoon in there! I haven’t seen the videos (yet) but will definitely watch them later on. Is this something open to the public?

Yes, Jay analyzes anyone who schedules an appointment. Not sure of the exact
cost, bu it’s several hundred dollars for I think a 3-4 hour workup.

I love the debate of heel vs forefoot striking! The video showed Mike Smayda, get therapy for an injury. Mike is definitely a forefoot striker. Don’t forefoot strikers have more problems with lower legs and feet while heel strikers have more problems with hips and knees? Also, I’d like to see a study showing whether forefoot striking makes a runner more efficient (less oxygen consumption).

Well done gentlemen. This is easily my favorite running piece I have read in 2011. This is an important element in the science of running. Great job!

Cheers-Patton

What I was getting at is it seems elite/pro runners develop a higher GRF, and apply it to the ground quicker- GRT( ground reaction time), and spend less total time in contact with the ground,GCT. The recreational runner, such as myself, applies less GRF, this force is applied over a longer time, GRT. Consequently, the GCT is higher.

I realize this is a different but related topic to your post which was directly about vertical impact loading rate. It’s just that it got me thinking about what the ideal curve would be. Possibly, a higher GRF curve with no impact spike, ramping up with a gradual loading- but delivering this force in the shortest time.

I too, recently changed to a running style with a midfoot landing and higher cadence. The change has been great but I’m trying to tie the form/technique to what the research is showing. Thanks……

I’m sure the conference in WV has inspired all of you to continue the interesting pursuit of knowledge regarding running form and reducing running related injury. I look forward to learning more as this continues to develop.
One thing I’ve come to believe regarding GRF and GRT, as well as Ground contact time (GCT) is a relationship difference in elites vs. non-elites. I don’t know if research has been done regarding this, but I suspect it has or is presently going on. The comparison is as follows: Elites= higher GRF, lower GRT, lower GCT Non-elites/less trained athletes= lower GRF, higher GRT, higher GRT Does this seem right and is it a function of more/better training? Keep up the good work, Tim

GRF increases with speed, and GCT decreases with speed, so yes the
relationship does make sense. What does GRT stand for?
