Agreed xman: I have saved this one for the Technical File. Gay is still pretty-much in a triple extension position in the vertical and his “free” foot is tucked way up high, so distance between hip and ankle is a very short radius (not sure that’s technically the appropriate word but you know what I’m getting at). The free foot crosses at or above the knee of the supporting leg in all the fastest sprinters. The high “carry” helps “save” the hip muscles and reduces the time taken (rate) in the stride “cycle”.
In addition, his shoulders are “down” which means they can rotate (although they look a bit inhibited here - see right arm squeezed tight to the ribs). When the shoulders rotate the hips rotate in lock-step. That helps with ROM and quality of impulse into the floor which will provide optimal stride length.
The arms move towards the centre-line which of course also helps synchronise the hip movement etc etc.
Hey, with all that going on, maybe that’s part of why he runs fast
Thank you for the analyse. Very useful

CHARITY AUCTION IN SYDNEY: THIS SHOE, WORN BY BOLT TO RUN 9.8 (EITHER IN BEIJING OR BERLIN, NOT SURE) WENT AT AUCTION FOR $33,000. THE MONEY WAS RAISED FOR PROSTATE CANCER RESEARCH, A VERY WORTHY CAUSE.

BOLT DRILLING THE LINE ; FREE FOOT STEPPING OVER THE KNEE OF THE SUPPORTING LEG WHICH SHOWS TRIPLE-EXTENSION IN THE VERTICAL POSITION. THESE ARE ALL ASPECTS OF CHARLIE’S FUNDAMENTALS !
Drilling the line was an exercise Charlie used to use with sprinters to teach alignements and relaxation. Nice picture.

Is it a skip A?
In the GPP DVD Charlie is showing a similar drill, but it is a sort of very slow-motion sprint.

Feet naturally aligned, so either side of the lane-line.
