Francis “Quick” Obikwelu in Athene July 2006
Anders I’m worried the photo-sequences may be slowing up the thread too much…
Some more Gatlin Pics
We have been talking about dorsi flexion, to me it seems that the further the distance the athlete competes in the more pronounce (or the attempt) the dorsi flexion is.
I guess that makes sense, sprinters done want to land on the heel (neither do distance runners), but distance tend to land and spend more time with feet on the ground each step.
Betty Cuthbert was even a junior as our nowadays standards, and i wonder how many junior Australians can run as fast as her.
Following an other thread about knee lift, this is pictures of Francis Big Obikwelu in Athens 2006 meeting (heats) at about 50m.
This looks like more a long jump run-up than sprinting. Look ROM for thighs and arms. And dorsiflexion (pictures 4 5 6).
Nice on PierreJean Could this be an example of too much ROM and too much time spent in the air = quite a lot of time wasted. What do you reckon folks.
Well KK posted one good example: Obikwelu who does dorsiflex when at top speed, but not any more coming “relaxed” to the finish line
Sorry I don’t follow you. What picture are you referring to?
Anyway, in the quoted picture the foot is a LONG way from touchdown.
By the way, the Betty Cuthbert picture is a good ilustration of normal plantar flexion before touchdown.
The shoulder rotation seems significant in relation to the belly button; though somewhat difficult to tell from this photo.
What of Gatlins’ grimmace?

And across the ditch at Wimbledon, French girl Amelie Mauresmo is … dorsiflexing 
re: dorsi-flexion. I get a feeling there is some confusion here. In sprinting the action is usually described as “big toe up”, which I take to mean partial dorsi-flexion, not total dorsi-flexion, which appears to be what people are looking for here. Am I wrong?
I would say, no, you are right .
People use the term dorsi-flex(ion) to mean Any Raising of the Foot (or Part thereof) Towards the Shin. Charlie refers to the raising of the big toe, some of the rest of us call it dorsiflexion…but most of us know the effect we are trying to get. (forgive us our trespasses… :o )
But the main thing is we get to look at some pretty good pix
