Would it be safe to assume a person coud run sub 11 in the 100m if they ran between 4.5-4.7 (electric timing.)
What would you say would be the minimum 40 yd speed in order to run 10.8 100m.
Also giving the proper track training, what do you think the correlation between the 200m and 400m and the 40 yd?
And finally, what do you think are the professional's best 40 yd? Jeremy Wariner's?
4.5-4.7 seems like it'd typically be about 11-low if both were FAT for a typical sprinter. I was a decath guy and ran 4.5 40's, with an 11.40, but obviously I was focusing on other things as well. If I had to guess the correlation between 200 m and 400 m times and the 40, I'd say it's r = .7 for the former and r = .65 for the latter.
Another question--is there anybody on earth can break 4 on the 40 yard dash? Seriously, ive had this debate with people and i need to know!
There ain't no corelation between tha 2. Da 40 yard dash is bogus.
Spearmon ran the 40 at Arkansas' pro day for the NFL draft back at the beginning of April and posted a 4.28.

didnt mo greene run like a 3.8 or 3.9?
Yes, there is a (positive) "correlation" between 40y and 100m times (and 200m and 400m times), but it's less than 100%. That just means that over a large population, people with faster 40y times will tend to have faster times in 100m/200m/400m, but you can't predict their times in those events precisely. (A lot of people seem to use "correlation" and "prediction" interchangeably. Except in the rare case of a 100% correlation, "correlation" does NOT equal "prediction.")
In this whole discussion of 40y times, remember that these are "football forties." The timing is completely different from FAT in track races: In a football 40, the timer (generally a human) starts his watch when the athlete starts to move; in track, the clock starts when the gun goes off. In other words, in the 40 the clock reacts to the athlete; in track, the athlete reacts to the clock. The time swing approaches .4 of a second.
I have no doubt that some track guys--GOAT comes to mind--could run a sub-4.0 (*with football timing*) for 40y. I'd be surprised if Wariner could do it, however. (Not sure he has that kind of acceleration.) As to anybody's running 40y in <4.00sec with *track* timing--there might be a handful of humans who could do that, but I can't think of anyone at present. Maybe Ben Johnson in his prime?
[By the way, timing for football forties is a lot more consistent than one might think. I remember seeing scouts from various NFL teams come to look at the prospects who attended my "football factory" grad school. These were humans--using 100th-second watches!--reacting to the movement of a guy 40y away. Yet for any one guy's run, the times of the scouts were amazingly consistent: often identical to the 100th, and almost always within a few hundredths of each other. This kind of consistency is why football 40's are a valid measurement--valid for comparing football players to each other, but not for comparing football guys to track men!]
As a football & track coach, I have to shake my head and smile when I hear 40 yd. dash times. First, most are hand held; and second, those that are electronic are not the same as FAT in track. The closest any human has come to running sub 4 for 40 yd is Ben Johnson in the 88 Olympics. His FAT for 40 yd was 4.38. Let's see, he was running in the Olympic finals in the 100, he was surrounded by the fastest humans in the world, he was on a fast surface wearing spikes in front of a world audience, and in case anyone didn't catch the news...HE WAS ON STEROIDS! Yet, people still believe Deion Sanders ran 4.29 BY HIMSELF!
I've timed hundreds of 40's and it amazes me still of the ignorance behind this over rated benchmark.
Kato that is the smartest thing I have heard all day. I love to hear football players who think that they can run a 4.4 40. I laugh every time.
Kato is very smart.......40 times are all about quickness.....football is about the short intense bursts of speed......and track is well....track. You can be very very quick but not very very fast....but most quick guys are also pretty fast.
And football coaches have the fastest fingers out there....I am sure they can manage just about any time they want their athleste to have!
