Bolt splits in 9.58

I think some of that strength will come just as he gets older, he’s only 23ish so still a fair bit of development to go.

Yes exactly. He should follow the natural pattern of strength gain with maturity but not try to advance it faster than that IMO

Question to your question.

Did he ever really lack extension or did it just look that way to most people? When I look back at Mo, Gatlin, Carl, etc the position of their legs at extension was in just about the same plane as Powell’s. Didn’t we discuss here how his extension was occuring in a more vertical fashion and thats why it appeared lacking?

For the most part everyone(sheep) will try to adopt the patterns of the fastest guy. It requires a little more work to actually figure out what they’re actually doing. I sure as hell didn’t think it was the reason for his success.

Also for Charlie and anyone else. What could the cause be for Powell’s apparent lack of extension or even stiffness in the hip region.

-Could he be consciencously trying to move a certain way causing just enough tightness to keep him from “opening up”. In a sense, not running naturally

-Could it simply be a cause and effect of his knee lift?

-Could his arm action improve:
I noticed his arm action during the prelims of Berlin changed(q-final mainly). This gave at the very least a visual impression of an ability to move better in the middle of the race.

I thought so too but some later still photos semed to indicate there was slightly less as the race progressed, possibly because of a redoubled effort to keep his knees up when pressed that might have over-rotated his pelvis which might have been been counter-productive. Certainly, his relay photos from Beijing show fantastic hip height which would seem to indicate full extension IMO.
I was told by a physio whose group was treating him thast the surgery on his torn pec reduced his ROM on that one side causing all kinds of compensation issues.

It seems to me that Powell’s stride get longer since Rieti’07 thanks to a larger range of motion including in the hip and knee extension.
Enclosed a sequence of Asafa during the Beijing relay @50m. Sorry for the quality, it’s better than nothing.

Complete extension there

Yup and this complete extension wasn’t there during the 100m individual races in Beijing.

Relaxation in the primes?
