O but im talking the 5/10k guys 
How much speed those guys got?
I believe they never ever run anything below 400m in competition. Galen Rupp recently ran arround 50s (indoors), but they run from strength and not from speed (very poor speed reserve).
If you are running 50 for the 400 / under 3:40 for the 1500 then you have to be able to break 12 or run very close to 12.
im kinda suprised this is even being talked aboutā¦
as far as i knew, it was known and much research has been done on itā¦
long achilles tendons are important factors in sprinting and jumpingā¦
i dont think there is much to argue aboutā¦
fibre types, practice, etc etc all play a role in wheather you can sprint or run distanceā¦
Who are you comparing tendon length to?? Yourself?? Remember this is in comparison to the Black population and Dix, Powell and Greene have (IMO) very average if not shorter achilles than the average black male achilles length.
Iāve never seen any research into achilles length and performance. As far as I knew it was a sound theoryā¦ however if it was so important then the top sprinters and jumpers would ALL have VERY long achilles, but many donāt! Lewis, Powell, Johnson, Dix, JESSE OWENSā¦ If extra long achilles were so important then how the heck did Robert Emmiyan jump 8.86 :eek:
What you donāt see is very SHORT achilles at the world stageā¦
You can have all the type IIb you want and achilles up to your ears but if it aināt all wired right then it aināt workin!!!
Jonathan Edwards and Stefan Holm have very low calves. There are plenty of sprinters with (relatively) low calves, but almost none with wide hips.
The physical (observable) characteristics that top sprinters seem to have are: Broad shoulders, narrow hips, relatively long legs, long achilles (double whammy of extra tendon and less weight at the end of the lever), small feet and possibly lark heel, although this is harder to see. Top sprinters also tend to be tall.
I read somewhere recently that Asafaās foot is 289mm, which seems quite big. Tyson Gay seems to have fairly wide hips for a sprinter.
well, ok but i disagreeā¦many of these jumpers have very developed soleusās which does make their calf (gastoc) look lower when in fact they arentā¦
also, you can NEVER say, that ALL or EVERYONE should do or be like any one particular thingā¦
There are many examples of extremley fundermental and accepted technical models throughout sports which some of the VERY BEST seem to totally ignoreā¦thats just sports and performance for youā¦(and please, iām sure your aware that the Emmyenn guy should not be placed in any catagory with other athletesā¦
However, i am positive that if you look at every guy under 10.20, under 20.50, over 8.30m, 17.20m etc etc and a very high percentage of them have long achilles tendonsā¦
1 or 2 or 50 pictures will not disprove thisā¦
Actually, I thought that I read a study where they re-wired muscle fibers to faster neurons and the fibers changed type. That is, you donāt have type IIb unless you are wired right!
Really? That is fascinating.
Tyson Gay most likely doesnāt have fairly wide hips. Itās more likely that his gluteus medius is so developed that it gives off the illusion of him having larger hips than he really has.
if it isnt wired right?
what does this meanā¦
Donovan Bailey had wide hips from what I remember as well as Walter Dix and Patrick Johnson.
Iām referring to the CNS.
yes cns is really imporatant, but the fact is that we can not control right, it is nature process,
ps. i think most important for sprinters are back, behind, quads, and strong foot fingers,
but some people have NO 1 AND NO 2 fingers the same lenght, mabey this would help them to run faster ???
Good thread.
My 2 cents.
All movement starts from the centre.
