During this race, he was timed in 2. Source: Hess WD. Timed in 0. Intermediate times were given to the media by Swiss Timing and were later published by Omega in the booklet Athletics Full Results Seoul In Rome on The times were later corrected in the Scientific Report published by IAF, and their best 10 m turned out to be 0. In Tokyo on Thus the 0. During the quarter finals of these World Championships, Carl Lewis was timed in 0.
New Studies in Athletics, no. In Los Angeles on No details were provided regarding the method, precision, and accuracy of this measurement. Peak speed located at 50 m recorded by a laser device operating at 50 Hz during the m Olympic final won in 9. For the first time, the system Laveg Laser Velocity Guard was used in an international competition.
Like the spidograms released in USSR in the early s, the laser records velocity oscillations that occur during each stride that allows counting the number of steps. Smoothing the curve is necessary to obtain an average speed over several steps. A speed curve graph appeared on TV within seconds after the final, showing a Symposium of the athletics, Bad Blankenburg, The authors also give 10 m splits from the smooth curve which result in a speed of The reason in that these times are calculated and rounded from the average speeds for each interval by the Laveg software.
Fredericks lane 5 was timed in 4. But the intermediate times are quite different and no details are given regarding the methodology:.
National championships quarter-final won in 9. Source: time analysis through the video material by Pierre-Jean Vazel. Peak speed located at The raw speed curve of the Laveg recording showed variations between The race was also filmed by 50 fps camera with digital timers activated by the official timing system, placed along the track at 20 m, 40 m, 60 m and 80 m.
It provided frames every 0. From until , it was required that the entire body be across the line for a finish, which is practically the same as the Laveg system, since the back is usually the targeted part of the body. I would like to thank Anne Atwater, Rolf Graubner and Hansruedi Kunz for their insights and explanations regarding their respective scientific research. Any corrections, amendments and proposals are welcome as this list is the first draft.

I can send you my scientific and methodical work describing the technique of running at sprint distances. Just send me your email address. Yours faithfully, Mekhrikadze Vitaly. The first 9. This may need to be confirmed. I think he also ran the first 9. This record was equaled many times. He also ran a 9. In , and Bobby Morrow tied the 9. In he ran a 9. The start of the race was wind legal and the end of that race the wind gauge went over the allowable. Had the wind been legal he would have run the actual first 9.
Dave Sime also tied the 9. He finished in second place at the Olympics behind Armin Hary after several false starts delayed the race. In the relay he ran his anchor leg M with a running start in 9. The relay time was Armin Hary set the world record of The first legal Bob Hayes ran the first legal 9. The auto timer clocked him in He anchor leg for the relay in was amazing as he was timed in 8.
The great Jim Hines tied the 9. The time was 9. This I doubt. Finally Ivory Crockett ran the first 9. Accuracy and auto-timing may have timed him even faster at 8. So there is some of the history. Just to add that when Morrow won the Olympics M final against a stiff 25 mph headwind He ran only a He tied all the records several times and the films of his leg speed when he ran are amazing because in the SF heat he tied the then OR of His speed and times suggest strong fast new records given no head wind and then add a better surface and coaching and his times might have been even more impressive.
While speculation this is entirely logical and possible or likely. This is fascinating! They are enjoying the film clip with Tommie Smith, not only to see Smith, but also to see the track that they ran on during that time before Bud Winter was able to get the all-weather track.
Also take a look at cadence for turnover which is the number of strides taken to complete the M Dash. It should be around 44 or so.
When Hines ran 9. He ran around 44 strides or less. In the Meter dash there is a 0. So when Smith ran his Hence the time of Borzov in ran similar in the M when he ran In Mennea ran When Gay ran a M exhibition straightaway he ran the first M in 9.
A similar situation but faster is with Bolt who ran 9. His 9. He previously had run Smith was Bolt in Your email address will not be published.

Chief among them was Lindsay, whose work getting Bailey first walking, then winning, helped popularize a method of sports-injury rehabilitation he helped pioneer alongside fellow chiropractor Mark Scappaticci, who also worked on Bailey in the pre-Olympic window. The holistic approach integrated the treatment of the injury with the training for the sport, mixing chiropractic techniques with traditional physiotherapy, not to mention various forms of acupuncture, massage and soft-tissue work.
In the years since, Lindsay has become a rehab specialist to the stars. And all those referrals, he said, ultimately stem from Bailey. Among the outside-the-box training strategies Pfaff prescribed for Bailey pre-Atlanta: Ten-second bursts of one-legged sprints done on a stationary bike. Bailey remembers his pre-Atlanta training regimen involving as many as six hours a day of therapy. There were drills done in a flotation suit in a swimming pool to minimize the load on his joints.
Eventually, there was track work. But there was never certainty. And you can easily fail. If Bailey had a bad habit as a sprinter, it was a tendency to overstride — to extend too far with his lead foot.
Overstriding, with a bum thigh muscle, could have landed Bailey in the fetal position. In the lead-up to the final, Lindsay said he remembers Bailey being unusually tense.
So it helped, in some ways, that the race was preluded by a series of false starts, including two that disqualified Linford Christie, the reigning Olympic champion. It was standard procedure for Bailey to find himself in fifth or sixth place at the metre mark of a big race, and this one was no different. But the picture improved quickly. In the closing steps of a metre sprint, even elite runners are decelerating.
Bailey became the fastest man in the world in part because he had a knack for being slower to slow down than his competitors. In the heat of Lane 6, with 83, fans at a boil and Olympic gold on the line, Bailey said he reminded himself to relax.
