Will someone ever run a sub-43 second 400m?

42.9 for a relay leg is about 44 flat for the open. minus maybe a little bit for being in lane 1.

Yes,

All records can and will be broken. It might take some bio engineering, but it will happen. We just need the fastest man and the fastest woman to get together and procreate. It is how all species have improved since the dawn of time.

I have ran a sub 43 300 so we're 3/4 of the way there, at least

The past-participle you're looking for is "run." It should be, "I have run...."

Obviously I was not looking for a past particle, just mentioning my plazing fast 300

In the finals if they don't kill themselves in the heats, you should see Merritt and Van Niekerk racing to the line for the first one. But maybe the heats will tire them too much for that and Zurich will be that opportunity, as it was for Reynolds.

There is a new well 5 years or so amphetamine based drug. Designer drug. Mix of modafinil and other CNS stimulant types. WHich is why most of the sprinters have slimmed down other the last few years. Look at Gatlin. Brommel, Meritt, Bolt. Basically skinny guys running fast. A little of muscle, but not like before. Probably since 06-07 time frame. Probably developed in Jamaica. BTW see April 1996 or 1997 SI cover and article that mentions Jamaica as a designer drug place.

Oh yes, cuz it's all about amphetamines, running sub 43.

Idiot.

Surely someone with sub 19.75 200 speed can "jog" through 200 in, say, a touch under 21 seconds and come home in 22?

I always think that most 400 runners don't pace their race right, or lack any decent sort of endurance.

No point in asking that here wrote:

The track and field fans on this board would love to see that obviously. So they could call him a doper.

So you just assume it will be a man to break the 43 second barrier, typical....

Not really how evolution works.

Pretty sure pacing is not a major obstacle for the very best runners at any distance. Pacing is a problem for youth.

Yes, this is interesting. Modafinal provides CNS stimulant effect in a way different than amphetamine, ie., receptor mechanisms different.

So you find a chemical that provides the stimulation by 2 different pathways. Is the net effect greater than each single pathway. Yes, if it's been used for 11-12 years.

Pretty sure you're wrong. The 800m women are atrocious at pacing and the men are usually too conservative at that distance.

Wikipedia:

"There are very distinct differences in the mode of action between dopamine releasers/substrates & dopamine re-uptake inhibitors; the former are functionally entropy-driven (i.e. relating to hydrophobicity) and the latter are enthalpy-driven (i.e. relating conformational change).[3][4] Reuptake inhibitors such as cocaine induce hyperpolarization of cloned human DAT upon oocytes that are naturally found on neurons, whereas releasing agents induce de-polarization of the neuron membrane.[5][6]

The wakefulness-promoting agent modafinil and its analogues (e.g., adrafinil, armodafinil) have been approved to treat narcolepsy and shift work sleep disorder.[7] These act as weak (micromolar) DRIs,[8] but this effect does not correlate with wakefulness-promoting effects, suggesting the effect is too weak to be of clinical significance. The conclusion is these drugs promote wakefulness via some other mechanism"

So you think men would be running 1:39 and women would be running 1:53 with better pacing?

Niekerk will shatter 43.18 very soon.

Only Merritt has even broken 44 this year and just barely. He is much faster over 200 but this has not made his 400 faster. I think there are 2 issues:

(1) The 400m is almost entirely about anaerobic capacity and tolerance, so there is little training leverage available. All systems turn on immediately so pushing more power development as in modern 100m training just consumes glycolytic resources sooner. There is only so much a coach can do in terms of balancing resources beyond what Clyde Hart has already done.

(2) The 100m is a more dominant event than it was when Maurice Greene and Michael Johnson (or Jeremy Wariner) were on top. So the best athletes are more likely to not do the 400 instead of the 100.

Nope. dont be mad because someone sees the world different and it correct. And it not ALL about amphetamines you gotta train. No one has run sub 43 Idiot

Very very good points. My genearl point is the designer drug, and Modafinil has some similar effects, not quite as strong a cocaine, but it cheaper and easier to obtain, versus getting Schd IV drugs.So you could "water down" the "stronger" one with the weaker one and beat the test and get the desired effect. Although at this point Moda is banned, but a similar drug or break that down as well and since they dont bio test amph/cns type drug. You can use it and not get caught.
