I’ve recently spoken to some coaches who believe that female sprinters need more speed endurance. Are there are some members who could explain why? Thanks ! 
The sprint time is longer and top the relative top speed is reaches sooner in the race so SE is more important IMO
FloJo had pretty good speed endurance
That’s one- now find another!!
Marion Jones?
No. Actually, if you look at her finish in Sydney, she slows up a lot! If she had the same staying power as Flo-Jo, who knows what she might have run- Marion was .06 faster to 60m than FJ.
That is a scary thought, Marion faster then FJ to 60m.
Easily believable though, as Flo-Jo wasn’t very much ahead half way through her 88 100m race.
Let me put it in context for you. Flo-Jo ran 6.86 to 60m in Seoul while Marion ran 6.80 to the same point in Sydney.
No doubt Flo-Jo had superb speed endurance but do you think she reached max velocity in the Seoul 100m final?
Evelyn Ashford also showed brilliant speed endurance in the 88 final, running 10.83 with her final two 10m splits (0.96) only 0.02 slower than her fastest between 50 and 60m.
Killer tailwinds help SE also
Flo-Jo was .91 for all four of her last segmemnts!
It maybe another 20 years until any female will be able to match those splits.
Correct me if I am wrong. I think Jones’s biomechanics doesn’t allow her to match FloJo in last 40m.
In what way does her mechanics prevent her from matching FJ?
Marion was breaking at the elbow (hands moving from very close to the torso in front to an almost straight arm position at the end of travel) in the Sydney
final, which I reviewed. With the elbow itself not really moving much, her hip rotation was limited, costing her stride length. Also, late in the race, her arms started moving back relative to her CM, causing footstrike further ahead of the CM, resulting in further deceleration (.06 over the final 10m alone relative to Flo).
With better technique in the upright portion of the race, she could have gone faster- there’s no doubt whatsoever.
