Many thanks to PJ Vazel for posting this on his Facebook feed! Follow him on Twitter as @pjvazel
FYI, PJ Vazel coached 2 sprinters under 10.00 seconds (Nigeria’s Olusoji Fasuba 9.85 100m, and France’s Ronald Pognon with PRs of 6.45 and 9.99 for 60m & 100m respectively. He is currently a coach for ALTIS based in China. You can read more about Pierre-Jean Vazel in my Freelap Friday Five interview and 10 Questions for PJ Vazel.
This 100m prelim report is from the incredible work by Leeds Beckett University, in cooperation with the IAAF, currently putting together the biggest biomechanics research project ever conducted in athletics during the IAAF World Championships London 2017.
In this prelim report you will find :
- Intermediate times
- Step length, frequency, contact time, flight time and also asymmetry left/right contact.

SUMMARY
It appears that reaction time and performance in the very early stages of the race remain key determinants of race outcome.
- In addition, to achieve high running speeds athletes should place an emphasis on speed maintenance as slight reductions in speed towards the end of the race may equally determine the outcome of the race.
- Reviewing Bolt’s profile from the time he set his world record suggests that elite sprinters exhibit consistent step length patterns and therefore variations in step frequency explain fluctuations in performance.
- Achieving high running speeds in the middle and late phases of the race does not always compensate for slower starts.
