Actually, the athlete doesn't react to someone saying go, but it's the person with the watch who reacts to the athlete.
In timed football 40s, the timer reacts to the athlete's first movement. When the athlete's hand leaves the ground, then the watch is started.
I have no idea as to how much of a time difference that makes up, though.
please somebody tell him how he calculated the 40 meter split, not 40 yard. I don't feel like doing the math...ok damn, i'll do it. 40 yards = 36.5 meters. that is 0.365 of 100 meters.
If someone has splits on his race thay can easily find his 40 yard time.
If you take an average pace he passed 40 yards during his 100 meter record it comes out too 9.59 x 0.365 = 3.5
3.5! now even though the start is by far the slowest part of the race, I can't imagine its any slower than 3.9
okay I didn't go to the chart before.
40 meters in 4.64 x 0.91 = 4.23 yards.
man they start slow. I have no idea how much faster he could go knowing he is just running 40 yards, but this does make it kind of a close race
Johnson is on record as saying he will NOT race Dane Rauschenberg! He understands that Dane Rauschenberg is the man when it comes to racing (any and all distances). So sure he could beat Bolt but don't even think about putting him up against Dane!
You misspelled "thay"

Actually, it proves how much faster Bolt is. One of those is hand timed, the other is FAT. Bolt has to react to a gun, thus adding more than a tenth onto his time. Johnson gets the advantage of starting when he wants, then the timer has to react. In this kind of race, Bolt runs no slower than 4 flat. Probably close to 3.9.
In other words, the clock starts before Bolt in one race.
Johnson starts before the clock in the other.
You are the dumbest person on this board, and you are correcting grammer? funny. You mentioned at least 3 innaccuracies as fact.
1. You mentioned "Looks like 10.38 according to this so he might have a shot at Bolt if he works on his start." The world record is 9.58. He can improve his "start" all he wants, he will have to be about 7/10 faster than bolt out of the blocks to even have a chance at losing a close one. impossible
2."So Bolt runs 4.64 through the 40 on his fastest race ever whereas Johnson runs 4.2. That is a huge difference." Huge difference there is, that you dont know the difference between 40m and 40yds. Yds, ft and inches should be outlawed anyway so i forgive you for that. Also bolts time was electronic whereas the 40 is hand timed.
3."They react to a gun? That's why Bolt is .4 slower? In the 40, you have to react to someone saying go. Saying go takes longer than shooting a gun, idiot. Apples and oranges is right". Do i have to rebutt?

Ugh. Alright here it is. Bolt's WR splits, which you can find at
http://berlin.iaaf.org/mm/document/competitions/competition/05/30/83/20090817081546_httppostedfile_wch09_m100_final_13529.pdfshow a .146 second reaction time, 2.89s over the first 20m (including RT), and 1.75 seconds over the next 20m.
40yards is 36.576m
If Bolt were to run the 40 at the combine, he wouldn't have to worry about reaction time, so a reasonable estimate of his 40 time is:
2.89 - .146 + (16.576/20)*1.75 = 4.19s
I don't know for a fact, but I believe football players don't get starting blocks on their electronically timed 40yd dashes. Anyone with sprinting knowledge want to estimate how much that would slow Bolt?
If Chris Johnson wants to race against Usain Bolt he should go about it the same way everybody else does. Enter some meets and prove that he can run 60 yard or 60 meters with FAT in something close to what Bolt has been timed at. You don't get to play in the Superbowl just because you say you want to.
I hope Bolt and his manager were never even in discussions about this.
Football players don't go to the combine "cold" either. They go to trainers to learn how to perform the different tests the best way possible. They're taught all the tricks-of-the-trade so to speak. Does anyone know if the football players have to be at a dead stand still before their start (ala sprinters in the blocks) or can they be rocking a bit to get good momentum towards their start?
Two things:
1) You didn't take into account the reaction time of the "starter" at the combine (I've heard mixed stories on how it was done there- button vs starter person). So your 4.19s is now in the low 4.00 range.
2) That 4.19s (now 4.00low) is still a SPLIT time. He continued on to run the fastest 100m in history. If he didn't have to run an extra 60m, I'm sure he'd be able to go a touch faster...even if it's just a tenth or two. Now he's sub-4.00.
HOWEVER, the blocks/no blocks is a factor, so eliminate one of the above to be fair. Bolt still goes 4.00low in the mysterious "football 40yd dash."
First off, you misspelled "grammer" so you must be the same guy misspelling "thay" above. Second, I never said he would beat him in the 100. I said he could beat Bolt in the 40 and 60. Third, Johnson ran 40 meters in 4.2, not 40 yards. Bolt ran it in 4.6, a difference of a small bus. And last, when I played football, my coach would tell us when to go so as far as I know, he's doing the same thing. So rebutt if you must.

Nobody says "GO" at the combine. They start when they want, and the timer then reacts. If you assume the reaction time for a timer responding to a runner is the same as Bolt responding to a gun (.146), then one must take a good .29 off Bolt's 40yd time out of the blocks to give an accurate view of what he'd run at a combine. An above poster said 4.19, and then asked about not having blocks. I say the benefit of starting when he wants, and then having a timer react to him, takes an additional .146 off that time. Now.. no blocks... maybe that lowers this number a bit.
I say Bolt runs nothing slower than 4.1-ish in a combine-style time. That being said, he crushes Johnson in any format.
When did Johnson ever run a timed 40 meters? To the best of my knowledge, they in the football world they only run 40 yards, not 40 meters. Why would he run a 40 meter dash at practice or the combine when everything is done in meters? If you have some factual evidence otherwise, please share. As other posters have pointed out, 40 yards and 40 meters is a big difference.
Seriously man... this is hard to read. Please stop doing this to yourself. You are not even close to anything resembling factual information. I am sure that somebody could make a case for what you are trying to argue. You are clearly not the one to be doing it.

Don't waste your time, Stewie. jf is a dolt.
According to IAAF Analysis Split Times, Usain Bolt ran his FIRST 40m in 4.65 seconds. Subtracting his reaction time which was .165 seconds, he ran the 40m in 4.485 seconds. 40 yards is a totally different measurement than 40 meters. 40 yards is equal to approximately 36.576m.
By simple ratio:
(40m/4.485)=(36.576m/X)
X=( 36.576 / (40/4.485) )
Usain Bolt's 40 yard dash would be....
4.1000

He's not asking to run in the Olympics, just an informal race, so your comparison to the Superbowl is garbage.
Chris Johnson probably could never beat Bolt but he's done enough athletically to earn the right to talk a little good natured smack.
I would like to see some of the all-time fastest football players line up with Bolt just to see. Darrell Green, Bob Hayes, Will Demps, Robert Smith.
I actually just looked up Green's wikipedia page. I knew he had a fast 100 time (10.08) and beat Carl Lewis but I had never seen his 400 time, 45.9. I guess that should have been brought up in the football players running the 400 thread.
Of course his comparison to the Super Bowl is unrealistic, but what if the tables were turned the other way and Bolt was claiming he could gain more yards than Johnson? People would suggest he lace up some cleats and get into a actual game. Why should Johnson expect anything different after calling Bolt out? At minimum, the race should be 60 meters or Johnson should man-up and run a full 100m.
jf, you're either a troll or an ignoramus. For your sake, I hope its the former.
Oh you played football. That clears it all up, thanks!
