Usain BOLT et le 150m

2009/05/17

Usain Bolt

Usain Bolt a remporté un 150m à Manchester en 14.35 par une fraiche température de 12°C. Le vent a été mesuré à 0.1m/s aux 100m et 1.1m/s aux 150m, sur une piste humide.

Organisée dans la rue, la compétition s’est déroulée sur un « revêtement Mondo de 10cm » installée « sur une plaque de bois et une structure métallique montée sur vérins et surélevée jusqu’à 1,10m au départ pour compenser le dénivelé de Deansgate », selon L’Equipe (17.05.2009).

Bolt a couru en ligne droite, alors que le 150m disputé en stade débute par un virage d’environ 65m. L’avantage de Bolt se chiffre à 0.15sec environ. C’est en tout cas largement mieux que tout ce qui s’est fait jusqu’à maintenant sur une distance peu disputée et non reconnue par l’IAAF. Les 10 meilleures performances de tous les temps :

 A Manchester, les temps de passages aux 50m et 100m ont été fournis par l’organisation.

Usain BOLT                  5.65 (4.26) 9.91 (4.44) 14.35
Marlon DEVONISH  5.77 (4.50) 10.27 (4.80) 15.07
Ivory WILLIAMS     5.79 (4.47) 10.26 (4.82) 15.08
Rikki FIFTON             5.78 (4.50) 10.28 (4.85) 15.13

A titre de comparaison, Donovan Bailey à Toronto, avec 75m en virage et 75m en ligne droite (en se retourant dans les derniers mètres) avait effectué, selon le Toronto Star daté du 02.06.97 :

Donovan BAILEY   5.74 (4.50) 10.24 (4.75) 14.99

 Les temps de passages aux 100m correspondent à leur forme du moment. Devonish a couru en 10.17 et 10.19 dans des conditions plus clémentes à Doha, et Ricky Fifton est rentré en 10.32 le week-end dernier à Orlando. Bolt, 9.91 sur 100m, est encore loin de son meilleur niveau, même en tenant compte d’un faux appui lors des premiers appuis en sortie de starting-blocks. Lors de son record du monde en 9.69 à Beijing, il avait couvert les 50 premiers mètres en 5.50 et les 50m suivant en 4.19, en perdant environ 0.07 dans son relâchement ostentatoire. Sur son 200m record en 19.30, Bolt avait couvert la section 100-150m en 4.52, en mineure partie effectuée en virage. Ses 4.44 en ligne droite, au même endroit, sont donc remarquables.

On peut imaginer que Bolt, valant 9.60 au 100m (théoriquement réalisables car son temps de réaction, sa fin de course et le vent n’étaient pas optimales à Beijing), puisse poursuive son effort en 4.40, ouvrant ainsi la porte des 13sec.

 S’il ne parait pas encore prêt à battre son record du monde du 100m (encore un peu tendre dans la phase d’accélération avec seulement une petite semaine d’entrainement après 10 jours de repos post-accident qui faisait suite à une semaine de glandouille médiatico-financière), il a déjà celui du 200m dans les jambes.

Tyson GAY aura soigné son genou

2009/03/20

http://www.trackandfieldnews.com/display_article.php?id=29651

Tyson Gay revealed during Adidas Training Camp that he injured his left knee in november, loosing 6 weeks on his preparation. The 100m US Record Holder (9.77), who had treatments in Europe and obviously moved a lot of weights while not beeing able to run, says that his leg is now pain free. Training five days a week, he hasn’t resume sprints on spikes yet. However, as a double World Champion (100m and 200m) defender, he is automatically selected for World Championships (15-23 August in Berlin), without having to take one of the first 3 spots during the US National Champs (25-28 August in Eugene).

Tyson Gay already had knee problem in 2007, a tendinosis on right knee prevented him to sprint after the US Championships in late June. He was able to win a couple of races in UK with sub-max efforts (10.13 and 10.02) before winning 3 gold medals in Osaka (100m in 9.85, 200m in 19.76, 4x100m in 37.78). One year later, he was victim of a hamstring strain on the left leg during the 200m quater finals of Olympic Trials. « I didn’t think it was going to be that bad because the initial pull really, really hurt, but the next day it felt better, » Gay said during the Adidas Training Camp. « But a little later, when we got a second opinion, I noticed a little bit of the tendon was torn, as well. That’s what made the process take so long. » Tyson Gay stated that injuries on the left leg on the hamstring/tendon in July 2008 and knee ligaments in November 2008 had no connexion.

However, observations on Tyson Gay in August 2008, showed that he wasn’t functionally set at 100% during the Olympics, where he failed to qualify for the final as he placed 5th in semi final with 10.05. These pictures were shot during the warm-up before the semi-final. After a couple of easy and sub-max checking starts, he tried this one at high intensity and his left leg couldn’t handle it as shown by the knee twist on his second step. This issue, both affecting his knee and self-confidence, plus quotes from Tyson himself saying that his left hamstring was tight before the race, shows that he was not physically ready and probably not healed yet in Beijing. The consequence was a performance more than two-tenths off his PB.

Considering that he is not pressed to compete at US Nationals to make the team at 100m and 200m, hopefully Tyson has enough time to prepare and get ready for Berlin World Championships.

Usain BOLT 45.54 analysis

2009/02/23

Usain Bolt ran the 19th 400m of his career in 45.54 on Saturday 21 February.

The race http://www.youtube.com/watch?v=puKnL6nNkr0

Bolt Wins 

http://www.reuters.com/article/sportsNews/idUSTRE51L0BB20090222
QUOTE He slumped to the ground after the race and was swarmed by a crowd of officials including medical personnel, who helped him stretch and rub his hamstring.

Intermediate times from the video (these are not hand time but my estimated electric times rounded to the nearest tenth).
100m 10.9
200m 21.6 (10.7)
300m 33.0 (11.4)
400m 45.54 (12.5) (21.6 + 23.9)

The model for 45.5, adapted from Moravec (TCH) and Schaffer (GDR) tempo tables :
100m 11.3-11.4
200m 21.8-21.9 (10.5)
300m 33.0-33.1 (11.2)
400m 45.5 (12.4-12.5) (21.8-21.9 + 23.7-23.6)

Bolt obviously went out too fast (10.9 leads to 44.0 according to Schaffer) BUT a 45.5 performer usually has a 10.4/20.8 background at 100m and 200m (from Letzelter). In August, Bolt’s level was 9.6 (rounded down because of the deceleration during the 9.69) /19.2 (19.30 was run against wind) but it’s difficult to estimate his current shape. From the shape of his training partner Yohan Blake (20.60), i guess Bolt is worth around 10.0 and 20.0 (which is awsome, assuming he resume serious training after Xmas, according to coach Mills). This still leaves a huge speed reserve while cruising to 100m in 10.9 and 200m 21.6, but makes his speed endurance index much lower than the 400m usual standards.
Stepping up occasionally to 400m, sprinters usually take benefit of a more cautious pace, so in that race, Bolt was probably able to run around his 45.28 PB set two years ago in May.

http://www.jamaica-gleaner.com/gleaner/20090223/sports/sports2.html
QUOTE « It’s part of his training, » Mills said. « What you saw is a big difference from last week, but that was expected. Each week, he will get better and better until we get right where we want to be. « Right now we are focusing on getting ready for our first international competition, which is in May, so we still have a lot of work to do to get him back in the shape we want him to be, » he added.

Comment les finales auront été gagnées

How Olympic finals were won and lost

By Mark Butler
BBC Sport’s athletics statistician takes a look at the numbers behind the big races

If you are a casual runner testing your fitness, try measuring out 100 metres and see how quickly you can cover that distance.

Then compare your result with the following figures: 15.4 seconds for men and 17.3 for women.

For many fit people, these might not seem to be tough targets and of course are far from the current world records of 9.69 and 10.49.

But consider that these were the slowest 100m sections covered in the respective Olympic 1500m finals last summer.

Every athlete in both those races ran 14 further 100m stretches faster than those times, and without a break!

These figures were obtained from a revolutionary timing system, where all distance running athletes each wore a tiny transponder on the inside of their front bib number.

Each time the runner passed over the 100m, 200m, 300m or 400m point on the track, his or her time was registered.

Therefore in the men’s 10,000m with 35 finishers, some 3,500 separate times were recorded.

It was all a bit too much to take in at the time, but now we have had a chance to take stock, can see a unique picture of how and when races were won or lost.

Among the highlights:

A fast back straight, rather than finishing burst, clinched victory in many races.

Britain’s Lisa Dobriskey may not have made the tactical error many believed in finishing fourth in the 1500m.

Women’s 10,000m champion Tirunesh Dibaba ran a section faster than Britain’s Mo Farah in his heat of the men’s 5,000m.

KILLER BLOW
In finals it is interesting to note that none of the new Olympic champions ended their race with their fastest 100m. The damage had been done before that point.

Not surprisingly, the 800m races provided the fastest movers. Two of the 800m men clocked a time of 11.7 down the back straight on the first lap in their preliminary races, but both went on to be eliminated.

Conversely, Canada’s Gary Reed left it too late. Seventh at 700m, he finished the Beijing final with a blistering 12.3 but ended up a frustrating fourth.

In the women’s 800m, the figures confirm the trademark move of the new champion Pamela Jelimo: a big effort on the final back straight.

The Kenyan clocked 14.2 for the section between 500m and 600m before slowing to 15.2 then 15.6. When Kelly Holmes won in Athens she finished faster than that, but from a slower initial pace.

Rashid Ramzi ran a tactically perfect race to win the men’s 1500m, with a scorching 12.6 on the crucial final bend.

His taller rival, Kenya’s Asbel Kiprop, clocked 12.8, which proved the difference, even though Kiprop was the faster in the finishing straight and closed to within 0.2 secs of the Bahraini.

Of course the figures alone cannot tell the story of the race. Someone forced to run wide on a bend would be actually be running further than 100m between the two transponder points.

DOBRISKEY TACTICS
In the women’s 1500m it was widely felt that Lisa Dobriskey had lost a medal through poor tactics, but the timing analysis does not fully confirm this.

In finishing fourth she ran a faster last 100m (14.6) than all but one of the other finalists, but the one quicker was Ukrainian Natalya Tobias, who Lisa had been tracking all round the final lap and who took the bronze medal.

Would they have been able to finish so fast if they had covered the courageous breaks made by winner Jebet Lagat (14.3 to 1100m) and silver medallist Irina Lishchynska (14.5 to 1200m) earlier in the race?

We’ll never know. We do know that it did not work for Bahrain’s world champion Maryam Jamal, who finished with only 17.2 after leading at the bell.

ETHIOPIAN MARVELS
Kenenisa Bekele and Tirunesh Dibaba each won the 5000m and 10,000m double and the statistics show that they won with similar tactics at the finish.

It is as if they take delivery of fresh legs in the closing stages of their races.

In the men’s 10,000m, Bekele simply changed gears 500m from home, moving down from 15.1 to 13.9 to 9600m and 14.0, 13.2, 12.5 for each successive 100m then 13.7 easing off.

Bekele was even more impressive at the 5000m, with three consecutive 100m segments under 14 secs from the bell.

In the brutally quick women’s 10,000m final, « Dibaba the Dasher » was able to run the final back-straight 100m in an astonishing 14 secs.

That meant she was moving faster in that section than any woman in any of the 1500m races in Beijing as well as Great Britain’s Mo Farah during his heat of the men’s 5,000m.

She had gone from 12 to 16mph in the space of 200m, which might not impress Jeremy Clarkson but is a deadly change of pace for a woman during a long distance race.

As with Jelimo, Ramzi and Bekele, her victory was forged before the home straight and she was able to slow somewhat without being threatened.

SPRINT ANALYSIS
Sadly the Beijing timing measurement did not extend to sprint events where the runners all keep to separate lanes, but it is hoped that this will be possible at future meetings.

We can therefore look forward to getting a record of the fastest of all individual 100m runs, that of the second half of the 200m.

Also this technology can give us a more accurate picture of the seemingly pace-perfect 400m tactics of Christine Ohuruogu.
Watch the Aviva International from Glasgow on Saturday, 31 January from 1400 GMT on BBC One and the BBC Sport website.

LaShawn MERRITT aura pris 6 sem. de vacances

2009/01/29

http://www.trackshark.com/features/tomborish/373/LaShawn+Merritt%3A+Looking+for+more+gold.html

Le double Champion Olympique ne participera pas à la saison en salle.

QUOTE “I took six weeks off [during the holiday season] to really relax and spend time with my family. Now I’m back in the heat of things and at this point it’s all about forward movement.”
The next month for Merritt will include plenty of base work where long distance plays an important role for a 400 meter specialist. Moreover, it’s the time of year where a long sprinter can really focus on keeping their legs fresh for the outdoor season.
“Over the next month I will just be doing base training,” Merritt said. “It’s going be a long season. My workouts will consist of doing 500 and 600 meter runs along with roadwork and putting in long mileage will help me transition to the core of my training.”
That training has been key for Merritt’s success who’s coach, Dwayne Miller, was named the 2008 Nike Coach of the Year.
[…]“I stay on a regular nutritional program, staying away from greasy foods is most important,” Merritt said. “I stay hydrated all the time, stretch as much as possible, knowing what my body can take, not overdoing it, and being smart about my craft.”
