Usain Bolt - 100m Beijing: 9.69 slow-motion railcam

[csportmaria]

his last 8 strides were all easy.. at 2.5m per stride thats 20m..

[Mattes86MX]

carlos condit is faster

[Manuelcr7]

this video shows so much

[volunteernation16]

I hate wondering what his time would've been if he didn't celebrate

[saeed4582]

That's brilliant.........

[MrNarutorasenful]

haha guyzz....im 13 and 173cm,maybe i will reach his height when im in his age:)

[fsujci]

he just doesn't look fast! I'm use to seeing short guys like Dix move their legs a million times a minute, but he just looks like he's prancing along...at world record speeds...amazing!

[kimahjungeunjin]

EGGS-ZEHGLEHHHH.

[JQX1]

HANDS DOWN THE BEST 100M RACE EVER,EVEN BETTER THAN THE 9.58 IN BERLIN

[btnh76]

Couldn't catch my cursor could ya Usain Bolt... Lol...

[bmxphenom50]

hes got like no running friction....so all he has to do is shoot up to speed...and then glide

[N3WTONVIENGKHOU]

bolt runs faster than the video can load.

[19Chr95]

he jogging xDD

[UncleRuckus101]

@roxtar55 I guess but I still say CJ2K would beat him to the 40 then after that Bolt would leave him

[roxtar55]

@UncleRuckus101 Not even in the 40.

[MrBusunglueck]

@UncleRuckus101 bolt is over half a second faster at 40

[UncleRuckus101]

@MrBusunglueck if ya say so

[vhickerson]

I can run that fast....if you pour gasoline on my ass and set it on fire!!!! Then again, probably not.

[salamipolk]

His slowmotion is even fast!

[UncleRuckus101]

I wannna see him vs. chris johnnson

[Omar10Barca]

He had a better time if he didn't celebrate at the end haha

[crespo03]

its absolutely astonishing how fast he is and he doesnt look like he is even trying

[chichibud31]

looking at the video in slow mo the only comparison which comes to mind is a V12 ferrari -bolt- going up against turbocharged 4 cylinder honda civics-everybody else..it's just the brute power he generates from his legs which separates him from everybody else + leg speed faster than that of shorter guys..a freak indeed..

[imfirinmahlazahs]

does he land on his forefoot and forefoot only?

[MrNielsen23]

@imfirinmahlazahs yes. its good sprinting technique

[isoloedyourmum]

love how he starts celebrating near the end lool

[CerebralPrince10]

Anybody notice that he was still trailing at 50M? Then to win by as much as he did is just ungodly

[isoloedyourmum]

@CerebralPrince10 yea cus in first 40-50m you must run with head down then gradually bring it up your ment to be trailing near the start

[MrNielsen23]

@CerebralPrince10 he is 6'5... it is more challenging coming out of the blocks vs. someone who is 6 foot

[roxtar55]

@MrNielsen23 Not necessarily. Just takes longer to get triple extension. However, he possesses longer levers, which actually make the load easier.

[MrNielsen23]

@roxtar55 i see where your coming from, but being a 6'3 foot sprinter myself, i know i cannot possibly come out of the blocks faster than someone who is say 5'7 or 5'8, without working on them for some amount of time

[roxtar55]

@MrNielsen23 Wow, somebody needs to hit the weights then.

[MrNielsen23]

@roxtar55 yeah.. i guess squatting 405 when im 16 isnt good enough.... which is also difficult when your 6'3"

[roxtar55]

@MrNielsen23 Wow that is pretty weak for having such long levers. i've seen guys 160 5'5" doing 500.

[MrNielsen23]

@roxtar55 you must know nothing about lifting, the shorter you are the easier it is to squat, the center of gravity is different, and of coarse they have to go down 7 less inches.

[xXTALLESTXx]

bolt is a top end runner i jes notice

[YouAreFATgay]

he has long legs so his step is bigger

[tomasinibull]

the fastest man ever ... for long time

[junmun123]

wow this is amazing!

[DynamicImpulse]

i've never seen this in slow motion or from this angle before. until now, i see that i didn't really have a true understanding or appriciation for how much further he was from the competiton. i don't think anyone can if they haven't seen this. he is so fast!!

[Manuelcr7]

Here you can see why bolt is much faster then everyone.

The angle between his legs is much higher then from other sprinters.

He have the highest knee drive.

[roxtar55]

@Manuelcr7 Well technically knee height is irrelevent. He's just pushing down into the ground with more force. However, he does have great muscle elasticity, which is muscle hardness combined with flexibility. And as you can see, his stride is larger than the others, which is partly due to greater muscle flexibility. Flexibility is such an undermined attribute in track and field, at least on the high school level.

[Manuelcr7]

@roxtar55 jop. Do you think static or dynamic streching is important

[codeyantiassembly]

@Manuelcr7 Rubbish. You need to watch the video again.

And anyway, I thought American Football was the only institution backwards enough to still believe "knee driving" is a good thing. Usain falls. Proof of that can been seen in that his feet land more parallel to his head and hips than his competitors do.

[jimmyjoemonkey]

@codeyantiassembly i think he meant knee 'lift'. high knee's is a good thing, if the knees are too low you'll limit your stride length and force output.

[Manuelcr7]

@codeyantiassembly I understand the pose method but he is so tall 6'5. So he has more ground contact time during the same speed. So he can produce more power because he has more time. The taller the athlet the faster he is.

[codeyantiassembly]

@Manuelcr7 Ah yes. Well that makes sense.

When you said "knee drive" though, all I could think of was this stupid Football coach showing his players how to run on a conditioning for speed DVD I have. He taught them, literally to lift their knees to their chests and drive them as hard as they could into the ground. Because, you know, it generates power.

Poor kids actually get exposed to this rubbish.

[tomase2]

powell wasn't as relaxed as he usually is in this race though which is why he didn't come second!

[santonio0011]

Even though Bolt won, Powell had superb form.
