Asafa 9.74 in Rieti!!!!!!

[kitkat1]

@pierrejean

I did the video analysis for Rieti’07, Gateshead’06 and Bruxelles’07- 2 points of view : from the crowd at mid way and at finish line (TV) with 50 frames/sec each. These 2 points of view unable to have 0.02 accuracy. I don’t have the first 10m - very difficult to read with end relay zone lines (yellow harrow) usually not alligned with virtual 10m line).

0.137 2.88 3.79 4.65 5.49 6.32 7.15 7.98 8.84 9.74 - Rieti’07
0.145 2.88 3.81 4.67 5.52 6.36 7.20 8.05 8.90 9.77 - Gateshead’06
0.148 2.91 3.82 4.69 5.54 6.38 7.23 8.08 8.95 9.84 - Bruxelles’07
0.145 2.91 3.83 4.71 5.57 6.42 7.28 8.15 9.03 9.96 - Osaka’07

0.91 0.86 0.84 0.83 0.83 0.83 0.86 0.90 - Rieti’07
0.93 0.86 0.85 0.84 0.84 0.85 0.85 0.87 - Gateshead’06
0.91 0.87 0.85 0.84 0.85 0.85 0.86 0.89 - Bruxelles’07
0.92 0.88 0.86 0.85 0.86 0.87 0.88 0.93 - Osaka’07

Weather conditions
Rieti’07 - wind 1.7m/s, temp 26°, humid 36%
Gateshead’07 - wind 1.5m/s, temp 25°, humid 57%
Bruxelles’07 - wind -0.3m/s, temp 17°, humid 72%
Osaka’07 - wind -0.5m/s, temp 30°, humid 62%

As it was mentioned by Charlie, the main improvement was done in top speed area, that’s the first time i find 0.83 by Asafa, and he did it for 3 consecutive 10m sections. I added Bruxelles because this was was impressive and held only 5 days after Rieti, in very different conditions. I don’t have crowd view for 9.78 so i can’t give accurate numbers.
Rieti’s final was the first time Asafa does less than 44 steps for a sub 9.90 time if i’m not mistaken.
Interesting to see the effects of wind when you compare Rieti and Bruxelles last 20m, almost the same speed, in one case he shut down visibly, in second case he maintained all through.

I cannot understand why they say you suffer from obsessive-compulsive disorder:p

Brilliant effort PJ

For the Rieti 9.78 0.0w final I counted 45.5 to 46 strides for Asafa. This when he kept the frequency going right until the end.

45.5 strides if you count one stride as each foot makes contact with the track and 46 if you count one stride as each knee begins to block.

this vid has the 9.78 final (beginning at 1:55 into the video) in regular speed, slow-mo, and front-on-slow-mo.

Asafa Powell 9.74 world record 100 m in Rieti [Italy] mondo

For the front-on-slow-mo the arms can be used to count the frequency or strides or what have you.

@John

why do you say that?

i think with the world allowing he means that if they are in PB/SB shape then the conditions would facilitate such a run, not that the conditions would make it happen in themselves, just that they would not impede PB/SB runs but rather facilate them.

@pierrejean

I might add that Asafa looked sore during Bruxelles warm-up, with right knee going outward for most of the drills and strides when he was decelerating. Thoughts?

Thanks a bunch for the breakdown.

Could it have been the groin bothering him again?

Maybe to soon after the wr run?

Hopefully he’s done for the season.

I’ve said over and over, you need to allow 10 days after such a performance to fully regenerate- and that’s historically with the performances of the times- now, with Asafa, the bar has been moved up and the recoveries may have shifted in favour of longer breaks.
In any event, does anyone know if there are any current plans for another run (Stuttgart??) or is he shutting down for the season?

Watch his 9.78 performance from the front view, and you’ll see a difference within the right leg upon ground contact. May be a structural difference or an imbalance between the two legs.

Thank you. I have not seen 9.78s until now. The most impressive run (start/finish) by AP so far (IMO).

[dr.sprint]

Suprised no one has noticed this…

1.7 wind behind him slowing down he runs 9.74.

With a 0.0 wind and an all out effort he only hits 9.78.

Does this not prove that wind aids in performance!?

…no shit. why do you think oba ran 9.69 and churandy ran 9.76

I was trying to say that all the runners in Asafa’s heat broke PB or SB, which is extremely rare, showing that the conditions were perfect, not only the wind. As for those who said the wind was too much, the triple jump average reading for 34 recordings were 1.65m/s so no poin to dismiss the wind gauge.

@kitkat1

do they have a winter in Jamaica?

LOL, yes they do, but the temperarture then is higher then in Europe in summer…

By the way: I really can’t understand the argument sg must be wrong any time AP runs a great time. Actually he ran 5 times below 9.8!

Then he clocked 9.84 under bad circumstances in Brussels (-0.3m/s, 17°C!). Only two guys ever ran faster than that (and two others, now off record). So even Brussels would make him 3rd fastest ever.

Only (2+2) other guys managed to go under 9.8 yet and they all did it once and never again!

The argument of “US patriots” is that

1. Mo is the Goat
2. Gatlin would have become the Goat
3. and Gay will be the Goat

For now for the rest of the world AP is the biggest talent and in fact simply the fastest 100m sprinter in history.

Mo is the Goat because he still has the record for sub10 (52) and is olympic champion and triple world champion at 100m. Asafa had bad circumstances in Bruxelles BUT Mo never get the opportunity to run at his peak in opened stadiums since he always peaking during major champs (world champ with 9.86, 9.80 and 9.82, the latest limping through injury in the last 25m, olympic champ in 9.87 by 19° with reaction time 0.197, these 4 races beeing held under close to nihil wind or slightly negative).
Asafa has still a long road to match Mo.

[Pioneer]

Powell will have to win in championship(s)? to achieve GOAT status(imho). Still, to his credit, in addition to his recent string of WR’s, perhaps he is changing part of the criteria with the excellence of his very best performances.

The total number of sub 10’s might not be nearly as important as the number of sub 9.8 times and, to a lesser degree, sub 9.9 times. I would think those marks would put him in very select company. He has 5 or so sub 9.8 times, I think?

He might be re-defining, in part, what it takes to be the GOAT.

ok, gotcha, it was a tense issue in your post and it sounded like you were saying all the runners would have to PB in a race for asafa to go sub 9.7.
