Why don’t we look at Martina’s 2007 Osaka performance as sub-optimal and the likely reason he ran 10.08 instead of 9.95 or something similar. His reaction time was part of the problem at .18s which puts him at 3.87s in the first 30m, which is not exceptional for an elite sprinter, but it’s not uncommon for those running 10.1s. The biggest problem I see is his initial impulse is not sufficient for whatever reason, most likely a problem with excessive movements in the transverse direction from excessive force application in the transverse direction (does anyone have frontal or over the top video of this race in the first 20-30m).
The reason why i don’t look Martina’s 10.08 in Osaka’07 as sub-optimal is that he was only 0.02 off his then-personal best set the same year (i’m talking about low altitude performances). Sure he broke 100m and 200m PBs in 2008, but in Osaka’07 he was at his best with his current abilities. However, Martina displayed same pattern in Bejing (9.93) 1 year later as he was 8th at 30m (like in Osaka) and finished 4th (was 5th in Osaka). As for reaction time, better be cautious with figures because the systems used in WC and OG are different. Could you expand on “initial impulse”? Are you refering to what occuring in starting blocks or first step?
Errors or Execution in a guy in the 1930s is an outlier. A percentage that represents an unlikely representation of norms. Martina may have gone 4.05 in the first 30m would that be the most likely to be influenced by lack of strength? The next question with this glaring first 30m is this the average, best, or worst first 30m for Martina. Finally since it’s rather slow will this be addressed or has he peaked in ability?
In Osaka, my analysis from the data recorded by Seiko shows that Martina had the lowest Fmax, as well as poor speed-force, explosive-force and start-force index.
Yoshioka or Martina are indeed out of the norm but that’s why we are talking about them. That’s not errors in execution but their usual pattern.
In Beijing, the data from Omega was not available due to no agreement with IAAF. However, i doubt there was significant changes in Martina’s pattern regarding his start.
Regarding Martina’s future development, i’m sure he can improve his short comings, to what extent i can’t say.
PJV,
What about sub 10 performances? As the athlete get’s closer to the ten second barrier the less likely you will see contrast as 80% of the top sub 10 athletes had split times that were not significant in disparity.

As for sub10, you can still find significant differences regarding 30m times. Martina is an example. Without giving 30m timings, it is obvious that Spearmon in Shanghai’07 (9.96)and Michael Marsh in Walnut’96 (9.95) took over a clear gap at 30m point to catch the leader (Gay and Boldon, respectively) and win the race in times which were their PB or very close to (in Marsh’ case). I bet the times were high 3.9. For similar 100m times, Jon Drummond or Raymond Stewart (both 9.96) were high 3.7.
We find disparities for the first 30m and last 20m of 100m races, sections between 30 and 80m have no significant disparity.
