Usain Bolt/Carl Lewis

[darwin553]

they all are decelerating in the 100 from 60 metres onwards. it is just UB' long stride length that gives the perception he is holding speed/going faster

Yes and how isn't that an explanation as to why he can make up lost ground to the 50/60m mark after a tardy start?

 

[ChewbaccaD]

Nothing here in the 2012 Olympic 100m final illustrates to me that Bolt is doping - where is the same acceleration as the other sprinters? The catching up at about the 50m and the breaking away is again consistent with his physique, is it not ???

Well, that's because you're a moron.

 

[ChewbaccaD]

Bolt clean? lol that is almost more delusional than thinking Dawg is clean. Imagine if Bolt starts doping then, he will run like 9.3 in the 100m

I think he can go 8.9...we know that one day, clean performances will overtake doped ones. It's a fact. Brailsford says so.

Thanks for that valuable contribution

Yes, except Bolt is hold more than the rest - relative, hence not blanket finish....

****HE HAS MORE POWER****

You have undermined your own argument, for the second time.

 

[mikeoneill]

This discussion has been brought up in other athletics threads. Carl Lewis was the benchmark. His early 80s times. Nothing under 9.9 seconds. All consistent and showing a natural progression.

lewis was on the growth hormone/thyroid synergistic combo

remember dr brown from houston and the braces

And how have you determined he has more 'power'?

 

[ChewbaccaD]

Because he didn't overtake them by eating cupcakes and rainbows.

Take a deep breath and read the posts again. I will count to ten ***slowly*** whilst you do this OK. If you do not get it by then I WILL either 1.chew my own hand off or 2. ignore you.

The only argument I can see about power is yours and you argue that the power he uses is abnormal considering his size and the amount of force that is needed to move his body but how do you explain his tardy starts? If he had an abnormal power to weight ratio, wouldn't he get off the line much better? Your argument makes no sense

Be..cause.....of Bolts.....size......he is slower.....out of the blocks. I did...n't say his power was abnormal......YOU DID......by un...der...mining your own argument........TWICE.

I was a kid in the 80s at best. I barely remember the 88 Olympics, but I do remember the mess around Ben Johnson. Was way too young to understand at the time. Also too young to remember who wore braces at the time.

But braces. Yeah, that's HGH alright. No two ways about that. I was willing to cut Lewis slack up until the mid 80s...based on his times and the reports we've all heard from later on...US track and field knew he was doping. They caught him.

Doesn't matter. Is just a hypothetical on what the best clean might hit. BC is probably closer. It is probably only just on 10 to 10.1 seconds. Which if true, sheds some light on my old theory...white men are just as fast as black men, or close enough to still medal. Hasn't been that way for a long, long, long time.

Not sure about that not seem the evidence, he definitely failed one test though:

His cough syrup excuse is obvious BS though.

If Carl said something to the effect of "it was a tough time and everyone was on something, I took stimulants to keep up but I didn't want to take anything heavier or more long term because I hoped more testing would soon be introduced" I might believe him but my inclination is to fear the worst.

he got the thyroid from dr brown in houston

the growth hormone don't work properly without thyroid

For more than a decade during the 1980s and ’90s, the Santa Monica Track Club, led by Carl Lewis and Leroy Burrell — who have both publicly campaigned against performance-enhancing drugs — dominated world track. After nine SMTC athletes took home medals at the 1991 World Athletic Championships in Tokyo, doping experts pointedly noted the unusual fact that seven of those medal winners, Lewis most prominently, wore dental braces.

The way I see it, growth hormone costs a lot, and, if it were me, I would want to maximise it as much as possible to get a better ‘bang for my buck’, T4 seems to be the catalyst here and without it, GH is a waste of money.

 

[horsinabout]

Wow didn't know this....the arthritis thing

"Athletic Championships in Tokyo, doping experts pointedly noted the unusual fact that seven of those medal winners, Lewis most prominently, wore dental braces. Less than 1 percent of the adult population wears braces, but crooked teeth is a common side effect of using hGH. Lewis, who never failed a drug test, now suffers from chronic, degenerative arthritis".

The braces are close to home for cycling......try the Manx missile.

The before



The After



Bad side effects

 

[mikeoneill]

ya

and growth hormone also causes arthritis

 

[oldcrank]

As a pure 100m only sprinter this is true but you can't tell me that his racing in the 200m doesn't prepare him better for the back end of the 100m.

Of course you are correct, his endurance and speed/endurance
also enable him to get through the rounds better than some
others as well. Mr. Bolt usually starts the season with at least
one competitive 400 and has expressed an interest in running
on Jamaica's 4x400 team at Rio perhaps.

 

[del1962]

He looked a bit slow out of the blocks today, nerous after his false start in last World Championships perhaps.

The larger the surface area of your body, the greater the wind resistance. You know from cycling how much energy is lost to wind resistance. This is why it is rare to have tall sprinters.

I assume that this increased resistance means it is harder for him to accelerate when compared to the smaller guys as well as some other factors.

WInd resistance plays less of a roll in running than cycling though, due to slower speeds, I doubt that in the initial out of the block speed is effected by wind resistance that much,

I think his stride length is something that gives Bolt an advantage.

a quick google search suggested around 13% of energy in wind resistance.

so over 100m 10% more resistance would be 0.1-0.2s difference. stride length, cadence, wind resistance, etc would all have some role at start, but I have no idea about how much effect each has as I'm not a sports scientist.

Suppose a longer stride and lower cadence makes it harder to accelerate though (but that's just a guess).
