Charlie thank you for your emphatic response that Renaud "presses up".
Can you elaborate and clarify why or if you think Renaud intentionally presses upward.
I can accept that this is what a vaulter reports as occurring and that the external observer believes they see.
Can the pressure the vaulter experiences on the inside pad of the lower grip hand be due to the pole reaction to the centripetal force created by the vaulter's powerful leg swing?
It is my understanding that Renaud is swinging from two pivot points formed by the grips on the pole and not just the top grip alone.
I am interested to hear your views on the issue.
