Am I reading this correctly? Heel striking is resulting in less ground contact time vs. forefoot striking? That seems a bit counter intuitive to me.
Wondering if others see similar.
What this graph does not tell you is the pace of the different runs. That will also affect the contact time. So if your foot strike type shifted to more of a heel strike at a faster pace, this type of relationship wouldn't be all that out of the ordinary.
All this data is really interesting to look at. Lots of unexpected relationships.
It looks like I speed up by both increasing my cadence and increasing my stride length to enough of an extent that I probably end up overstriding. Hmmm.
Have you noticed a relationship with any of your other metrics -- like shock?
