re: What would Usain Bolt's 40 yard dash time be?

The real question is what would be his 40 time if he ran top speed the entire time.

Laugh all you want, it is obvious you don't have a clue what you are talking about. The track guys in this thread have even came in and said it would be tough for Bolt to beat Trindon in a 40.

And he is world class in shorter distances. So its more like But But But, Bolt is the fastest guy in history at 100meters.

What do you mean? Like if you gave him a 50 meter running start?
Bolt's fastest 10m splits are .82 and he actually can sustain that speed for 40 yards (but not much longer) so the analysis is pretty easy: .82*3 + .82*.65 == 2.99
But that's sort of a silly question. You don't usually give guys 50 meter running starts.

Bolt would beat Trindon in 40 m

First of all we are talking about 40yards, so it is even shorter then 40 meters, and I never said Bolt wouldn't beat Trindon at that distance. Pretty much everything I have said has been It would be really tough for him to beat Trindon at that distance and it would be. If they raced a 40 yard dash, no one would be surprised if Trindon won and if Bolt were to win it would not be a blow out.

Look I ran the math in another thread and when he ran the 9.58 he would have crossed the 40 yard mark at 4.201. This is going off of the gun I think we could safely say that he has a 1/10 of a second reaction time meaning I think he would be in a legit 4.1 range at the combine.

Techincally, you drop .24 seconds from gun to laser time. That would give him a sub 4. However, the only way to really know is to see him run it.
FWIW, I think Bolt could run 4 flat on an elite mondo track in spikes and shite with a laser timed system. I also think a guy like Chris Johnson (at his fastest) could run like a 4.1 on a track in track spikes.

i just wanna see all this shite go down. put bolt and a couple other track guys (powell, gay, etc...) and then throw in dudes like chris johnson, lebron, cristiano ronaldo, walcott, lennon, bale, westbrook (basically who the frick ever from sports) and race these bitches. would be awesome

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 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: 4.100 seconds
By simple ratio:
(40m/4.485)=(36.576m/X)
X=( 36.576 / (40/4.485) )
Usain Bolt's 40 yard dash would be: 4.100 seconds

They would lose cause their form would suck and they do not train exclusively for it, but it would be sick.

That equation assumes uniform speed throughout. The better measure would be to take his 20m split and add that to ratio like you have shown. Still not perfect but much better. My guess is he was in the upper 4.18 range.
ETA: frick it. I ran the numbers:
Using the chart on page 3
40 yard = 36.576 meters = 30 meters + 6.576 meters
6.576 m = 7.19 yds
40 yard time = 30 meter time + 7.19 yard time
30 meter time = (0 to 30 m splits - reaction time) = 3.615s
7.19 yard time = average of 30 m and 40 m time divided by 10.94 yds multiplied by 7.19 yds = (.89s/10.94)x7.19 = .585s
3.615s + .585s = 4.200
someone can check my math and my assumption if they want

Considering that 100 meter runners do not reach top speed until AFTER 40 yards--the comparisons are irrelevant!!!
The great sprinters are undoubtedly FASTER at their peak than football players at any time during the 40 yard time trial...
Compare the split times/converted to yards. NO ONE has ever run faster than Bolt between 60 to 80 meters!
And this topic should not be about 40 time--but about who is FASTEST!
Taking Bolt's top-end speed and working it into a self-start (contrast to a reaction-start in track) = a 40 time of 4.0.
Again, Bolt cannot reach this unprecedented speed in the first forty yards. This discussion completely hypothetical.

How the hell did you respond to me and ignore everything i wrote? I laid it out as simple as day.

Bolt reached 40m in 4.64. The timing for NFL 40y starts when the athlete makes their first movement (correct?). To adjust Bolt's time toward the NFL time, you would subtract his reaction time, .146, which would bring him to a bit under 4.50 for 40 meters.
You would add .24 to all of the NFL guys' times since they are not using fully-automatic timing. That would put Chris Johnson at 4.48 for 40 yards, which is less (considerably) than 40 meters.
...and in your opinion what are the effects of the starting block vs. no starting block and running on a track vs. running on field turf?
Posted on 8/5/12 at 8:23 pm to iPadThai
This is a great question. I think it would be over 3.8 for sure.

Link that thread. Your math is off.

You can't do it that way. His speed wasn't constant. It was still increasing when he hit the 36.5 meter mark.
Everyone please disregard this guy's analysis. It is garbage.

No it isn't it has been confirmed by other posters. I made a huge chart that showed the splits and how everything worked.
