 Posted: Tue Jul 27, 2004 1:12 pm Post subject: 40 Yard Dash Times |
 |
|
You know how college kids and pro football players are clocked at 4.2 and 4.3's and some are down into 4.1's. Well I just figured there is no way they can run that fast. More like 4.4 and 4.5's, and even that is pushing it. A 4.25s 40 yard dash, would figure out to a 4.675s 40 meter dash, and that is faster than every other 40m split except for two MO Greene splits. Which is ridiculous. Maybe a couple 4.3s 40's but even thats hard to believe.
Whats all of your opinions on this subject?

40 times are about as relevent as the color of FloJo's nails ... When I played football in high school I was timed in 4.4 over the 40 ... But my 100 was only 10.4h ... And I wasn't a great starter ... There's no gun ... The clock is usually started on movement ... And quite frankly it all depends on who's holding the watch ... Now my coach was actually very good with a watch - he taught me !! But still, put Mo in your typical 40 and he'd have to be under 4.0 ...

Under T&F hand timing rules, you'd have to round up to the nearest tenth, add 0.24 auto conversion, and probably add another 0.1 for lack of the gun reaction time. That just added 10% to the total time, and it doesn't even take into account rolling through the start that is often allowed in those tests.

| remember Ben Johnson the sprinter from Canada who got caught on steroids and got his gold medal taken away? his 40 yard dash time coming out of blocks on a track with fully auto timing was 4.36. remember how he blew everyone out at the start of that race? nobody can run under 4.3. thats what a track & field article stated back then and I believe it. |

Was that 40y or 40m? If yards, then where and how was it timed/measured?

By using many formulas and split-times from Ben Johnson's 9.79 & 9.83 100m sprints, it has been worked out that his 40yd split-time from his 9.79 & 9.83 runs were both the same (both at 4.37+)
It appears that Mo has the fastest 40yd time (an en-route split-time) from his 9.82 run from the 2001 Edmonton Worlds 100m final. His 40yd split in that race was worked out to be that of 4.34+
I posted the same info. on Ato Boldon's forums the other day, as someone asked the same question. (Sorry for the size of the link!)

The problem with working backwards is it assumes hitting the fastest possible 40y en route to 100m is desirable, whereas in fact it usually is not. If you max out in the first half of the race, there's nothing left to finish with. Unless, of course, the formulas can somehow account for how much is left in reserve in an en route 40y...

Yeah ... Kinda tough unless you have all the segment times ... Then of course it is easy ... Otherwise you have to make the assumption that everyone rund the 100 the same way - as far as expense of energy ...
Either way the 40 is such an irrelevent distance to time ... It only means anything to football folk ... And they don't use it with much success anyway ... I'm not sure that football people really understand speed ... Its just something convenient for them to toss around to say yea or nay when "evaluating" athletes ...

When people are doing the NFL 40yd dash test, do they have to wear the entire NFl uniform? Or is it done in 'track clothing'? Thanks in advance

Shorts, t-shirt, and shoes ... Typically football shoes .. But now they are almost as light as track spikes ... Maybe done on grass, maybe on sidewalk type surface - mostly on the turf though ...

... and often with a running/moving start and with oh-so accurate hand times... 4.4 might as well be 4.9+, as far as accuracy is concerned.

From the Video-Analysis split-times I've seen, the fastest unofficial 40yd time is Mo's 4.34 from his 9.82 ED run and the fastest unofficial 40m is Mo's 4.64 also from his 9.82 ED run
From Scientific Analysis Big Ben had 4.37 for 40yd from his 9.79 Seoul run and his 40m in that race also happened to be his fastest, at 4.66.
Also from Scientific Analysis Bruny Surin had 4.37 for 40yd and 4.68 for 40m. Also tied at 4.68 for the fastest official 40m split are Leroy Burrell & Dennis Mitchell within their Tokyo '91 World final 100m runs (9.88 & 9.91, albeit flyer, respectively)
40yd times for both: Leroy Burrell 4.37 & Dennis Mitchell 4.38
Looks as if Mo is the fastest, and probably will be for some time. Prehaps if this event was run at a meeting for sheer exhibtion value, some of the fast starters could crank out a sub-4.30...you'd have to catch a flyer to do it though

I have a hard time believing any analysis that doesn't have Ben at the top of the heap for first 40m/y... Been quite a while since I watched the race, but when you've got the fastest overall time ever run and the fastest start and one of the slowest finishes making it up, it doesn't add up that the intermediate times wouldn't be the fastest.
