Does anyone have stats on this? He can't be far behind bolt and gay regarding his
Top end speed. Just saw him blow by Collins after being 5 meters down...amazing
the difference in top-end speed amongst world-class sprinters is probably not noticeable to the naked eye. What is noticeable is those who are able to maintain such speed (or close thereto) for a longer period of time, thus giving the illusion of greater speed.
running is all about trompe l'oeil (you get fooled: what looks like more speed is actually less loss of speed)
I don't have any calcs readily available. However understanding elite sprint distributions I would think that his highest m/s rate was slightly less than those you mentioned. Contact length, rate of relaxation and imposed stamina development might have much to do with the high quality of sustainability at that rate. Perhaps, at that point in the race, equal to those again that was mentioned.

It does depend (to evaluate in the the general sense, the max. velocity) upon where this "blowing by" occurs. As alluded to above, if it's very late in 100m, then it might be more a demonstration of speed endurance. If it occurs earlier as in around 40-60m (a mid race pick-up or another gear that can be reached that others in the race might not have) then it would be more of demo. of at least near top end. If this separation occurs at the 60-65m mark then it would have to be, in most cases, max. velocity. The highest speed will occur for the best during approx. the 6th-7th second of sprinting.
I think these speed numbers are accurately derived from the 10m splits and can be found. Certainly the coach of every top tier sprinter knows their athletes top end speed exactly.
bet they don't: the number of meets for which there are believable 10-meter splits is very small.
I've never understood why big-time sprint coaches don't employ radar guns like baseball does. You can hook it up to a printout that shows mps continuously from start to finish.
Baseballs are a 'point' source, with no moving parts. Humans have this habit of moving their arms and legs around and gyrating their center back a forth relative to their center of mass.
And that assumes that your gun is actually of tight enough focus (I have no idea) to have only the desired athlete giving off a reading. Not to mention the need to have a perfect line of sight, which is a virtual impossibility unless you're on the photo platform (if they have one, and the photogs don't kill you for being there in the first place).
Lemaitre did compete in 2011 worlds in 100 and 200 and 2012
Olympics in 100. Would like to see fastest 10m (or 20m) splits for these 2
Competitions or even back to 2007-2009 if possible.
Is there any evidence that leg length is related to maintaining loss of speed? Any mathematicians want to weigh in?
Now there's a can of worms: Did Mike Agostini (Trinidad & Tobago/Fresno State, 9.3 100yds. if memory serves) slow down as much as long-legged Ray Norton? Such different styles you'd have no idea who was running better looking at them isolated.
As for Mathematicians, I wouldn't go making theoretical predictions when muscle type has so much to do w/ both turnover and rebound impetus. For theoretical vs. empirical projections, I cite Shotput, where angle of release is somewhere below 40 degrees (37 is cited in one of the Throws Manuals): The 45 degree nostrum only applies to projectiles "fired" from the same level, usually ground (or gun muzzle, typically aimed at a target on the same horizontal plane, earth curvature excepted, but also subject to calc), whereas a Shotputter releases closer to 2m high. Moreover, the lineup of arm/shoulder musculature helps explain the much lower (than adjusted theoretical calc) optimal angle. Try it "at your desk" to see how it looks and feels; that's why a dropped elbow is such a no-no in SP, leading to a weak, looping throw.

They could measure the speed of the athletes going away from the blocks. Possibly even have a 'target' on their back and train the measuring device to ignore everything else?
Here is the link to the 2011 Daegu World Championships IAAF Biomechanical analysis. http://www.jaaf.or.jp/t-f/pdf/Daegu2011.pdf . Unfortunately, these "scientists" were probably not coaches/athletes or even fans...they use some odd distances, but they were thorough as the HJ, PV, SP, LJ and sprints were high lighted.
