dorsiflexion - sanya richards

Ok but Charlie said in Forum Review that he wouldn’t recommend pulling the whole foot up, he says you should just cock the big toe up, so… Still confused

Look at Ben’s foot on the front of speed trap if looks like his ankle just neutral but his toes are tensed.

I know the point of dorsiflexion or big toe up is to have calf muscles I think pre-tensed so which is the correct way?

and of course Gatlin dorsixflexing lead foot …

Hey Kit Kat, you mind sending a copy of these shots over to the nimrod at Harvard who say foot preparation doesn’t matter - and to that pal of your who thinks that dorsiflexion should be maintained THROUGHOUT the entire stride cycle?
One picture replies to two wiseguys!

Hey Charlie, so when you say you should have the big toe cocked up you mean the whole foot?

:rolleyes:

Rachelle Boone-Smith wins 200 at US Champs 2006

She won in 22.31

by the way, pretty good example of dorsiflexion of the lead foot - even suggestive of an emphasis through the big toe here

Jamaica’s Sherone Simpson runs 100m pb in 10.82, backing up from 200 pb of 22.0, June 2006. Long levers, short torso, classic athletic build

Jeremy Wariner, lead foot dorsiflexion in preparation for contact . . . also quite a lean infield, but not “break” or bend at the waist, no collapse of the left hip (toward the infield)

How much is lean dictated by speed? ie the faster you are the more lean you require? :confused:

Also what about the lane you get? I am guessing this needs to be accounted for as well…easier if you are a stud like Wariner as 99% of the time he will get 4 or 5.
Is ther an ideal lane? is it dictated somewhat by the individual?

so many questions :stuck_out_tongue:

Atleast indoor you want to get the outside lanes in the 200 and 400 due to the tight bend your body has to adjust to whipping around the turn, I believe it causes higher ground contact times among other things and in turn causes you to slow, I’m sure someone else on here with more knowledge can elaborate.

In terms of outdoor, I would believe the same would hold true and the looser the turn the better, but I am not as sure about this one. I would be willing to speculate that the psychological factors that go into the lane assignment outdoor is just as much of a factor since the turn is not as sharp, but this is just speculation and once again I’m sure there are people on this forum better suited to answer this question.

Asafa Powell training - dorsiflexion of the lead foot pre touchdown

asafa dorsiflexion of lead foot pre touchdown . . . and apparently zero dorsiflexion of the trail foot even as it approaches the tucked position

Asafa in training, the trail foot appears to be approaching if not already partially engaged in dorsiflexion as it tucks beneath buttock and approaches the cross-over at or above the knee of the support (grounded) leg. In this case the support knee is quite bent, which suggests either he is about to rapdily extend primarily vertically or Asafa’s coach is going to castigate his man for a technically sloppy training run.

The lead foot at pre touchdown (middle picture) does not look dorsiflexed to me, rather slightly plantarlexed.

The range of movement from neutral to fully dorsiflexed is about 20 degrees so It seems like there is at least 30 degrees of “unused dorsflexion”.

At the third picture the foot with ground contact is dorsiflexed (of course).

I hesitated to post the middle shot, not because I think there is big doubt about dorsiflexion of the front foot but because the image is a blur. I decided to mention dorsiflexion because of the position of the toe which does appear elevated. If I ever come across more pix of Powell I will post them for opinions :slight_smile:
