Your points are very good. CJ is an amazing athlete, and it's a shame they don't have Superstars anymore, as it would've been good to see him in action if he did it
People are forgetting that Chris Johnson 4.24 40 yard dash is so remarkable. He has no starting blocks, just a 2 point stance and electronic timing. Justin Gatlin finished right behind Bolt in 2012 and when he was banned from the olympics for doping he tried out for NFL teams. He raned a 4.41 forty. And that is with screwed hand timing wich favors the runner. Johnson raned a 4.24 on electronic timing which is hard to do. Even world class sprinter Gatlin couldn't even crack a 4.3
@PowerSprinter I think they have a laser plane and when you brake it, the timer starts. So I don't think you need to add on the time for the starter's reaction. I believe the 4.24 he ran was electronic as well.
@WCCanuck true that. And the fact that in the 100 you run the first 30 meters just to build up to reach your top speed later and extend it as long as possible. Whereas in the 40 you jsut get the wheels spinning as quick as possible, thus limiting your long term top speed.
@Peralasis take bolt's record run. In this run he took 4.64 seconds to get to 40m. But he had a reaction time of 0.15 seconds (combine clock starts after reaction). So if the combine was 40m he would have ran it in 4.49. But the combine is 40 yards, which is 36.57 meters. Converting his 4.49 to this distance gives 4.19. To do this calculation take his 40m time and subtract the time it approx takes him to run the last 3.43m, using his average speed between 20m and 40m (4.49 -3.43*(4.64-2.89)/20).
You're absolutely correct regarding him accelerating through that 30-40m but it was factored for in the margin of error of "± .04s." If you look at his 10m split between 40-50m it was only .03s faster than his split between 30-40m so by that point in the race he really isn't accelerating very much. If there were no margin of error, you'd be correct, but any discrepancy due to his acceleration over that split should fall well within that margin of error.
Proper track timing the sprinter starts average of .25 sec after the time starts. In 40 yd dash the time starts .25 sec AFTER the athlete starts running. This makes track times look a whole half a second slower than dash times.
Jim Brown was one of the greatest football players that has ever lived. I think the fact that he was just stronger than everyone on the field tends to make people think less of him from a competition standpoint. Kinda like people do Wilt Chamberlain cuz he was just bigger than everyone else. I actually know a lot of people who do bring Jim Brown up quickly when discussing greatest RB's.
I know. I've looked into this thoroughly and I actually base my opinions off of empirical evidence instead of just accepting what a TV personality says. BTW, as far as Bolt not being one of the fastest accelerators, at his best he's right up there with the elite starters of track and field. In his 100m WR performance in Berlin he was already leading the field by 30m (less than 40yds) well before the half way. He usually doesn't get off the blocks as quickly, but by 20m he's making up ground.
@Acid346 I think rather than looking at it that way, we could say that it points out how athletic and talented even the average professional athletes are.
I know this is an old video but may i ask you a few questions? 1: What cable provider do you have? 2: If you still have that tv what are your color settings on? Thanks!!!
I've only ever seen the videos posted online after. Always looked like they get themselves ready and start when they please and not when someone tells them to. Also, if they are using electronic "eyes" or timing gates, they don't start until the first one has been "broken" (i.e. first laser has been tripped) so it wouldn't matter if someone started them, the reaction time still wouldn't be timed.
@Rage23S well alot of a reciveivers or runnanbacks training is sprinting that includes just about all the football positions most football players in college and in high school do track
Just realized that Sport Science forgot to calculate in reaction time. Bolt ran a 4.3 WITH his reaction time. If you subtract that (.146), Bolt ran a 4.15s 40m.
wrong if you plot bolts 9.58 as a curve against time from the 10m splits you see that his 40 yard split is roughly 4.35s. take off his reaction time (based on the nature of the combine timing) and you have roughly the same (slightly lower) as johnsons time. then take blocks into consideration and you have about the same id say. an interesting comparison would be ato bolden, cos his start is ridiculous
To me Bolt is known more for his next gear than his initial acceleration. You watch his races and Bolt seems to just be starting to hit the after burners while the others are already at max their max. Anyway, Chris Johnson has world class speed. He's taken a step back since signing that big contract, but that's pretty typical, for whatever reason, in the NFL today.
@zislam159159 Ya a lot of people think they are going full speed the whole way but its not actually physically possible to sustain full sprint that long, theres more technique to sprinting than people think.
I said over the last 6 weeks CJ leads in rushing. Not the whole season. It's a fact. The record prior to CJ was in fact, 2 career 80+ yard TD's for a career. It is CJJ's with 5 of them.That is also a fact. Now, how is it that I don't know what I'm talking about? lol
Whose did? There's no reaction in the NFL combine as it starts on movement. Bolt's time does include reaction because it's from a 100m dash and extrapolated. But his reaction is given so you can easily subtract it.
How did 4 RB's go ahead of him in the draft? WTF were those teams thinking? Not to say those RB's aren't good, but seriously, watch his college highlights! How could anyone justify taking another RB ahead of him? Chris Johnson has the agility of Reggie Bush, the vision of Barry Sanders, and the speed of, well, Chris Johnson. He is exceptional at blitz pickup for a smaller RB, and is a very good receiver as well. He also raerly fumbles the ball, and has never missed a Titans game in his career!
@wcinthehizzywhat Yes. It's awesome to watch Adrian but I don't know how long he has left to be elite. Chris Johnson is as good at not getting hit hard as Adrian is at hitting hard. CJ always makes that last shift or movement to avoid hard collisions. He will last much longer than Adrian. It has been a joy to watch them both over the last 3 years though. I can tell you that!
no nfl player will beat any top class sprinter. in fact no sportsman apart from other sprinters will beat a top class sprinter because these guys devote everything in their lives to being faster, from what they eat to how they train
not what I think, what I know. yeah they couldn't agree because of the conflict between pathetically short distances and distances that are long enough to determine true speed
@icecru2 The splt for Bolt are in METRES, 40yards is 36.6m (to round it up). I've been around Track all my life and whilst I have the greatest respect for the speed of the top Football players, they wouldn't touch a sub10 100m guy over 40yd
@zislam159159 40 yards is'nt used to measure top end speed. The average football play is between 4 and 5 seconds. The average football players runs 40 yards between 4 and 5 seconds. It's a measurement to see how fast someone will be on an average play.
@icecru2 Without bombarding the place with numbers, Bolt went through 40m in his 9.58 100m World Record in 4.64 and went 0.86 from 30-40m (11.63m/s) (40yd is 36.576m, so 6.576m and average speed of 11.63m/s takes 0.565.......30m split of 3.78 + 0.565 = 4.345 (4.35). And that is with a reaction time of 0.146, the NFL Combine times don't require the player to react to anything and time starts when the player releases their hand from the start line. Bolt's raw 40yd would be 4.19-4.20 at the slowest
Do you have any idea on what you are talking about? Bolt offical record time was 9.58 seconds in the 100 meter compared to Bob Hayes record of 10.06. Just under a half a second. Also, its not very hard to convert a 100 meter time into MPH. Also, Bolt may in fact could run a 4.19, but Bo Jackson ran a 4.12 and 4.18 within two days of each other at the 1986 Combine. Its not uncommon to have Olympic caliber athletes in the NFL.
thank you been looking for this everywhere!
i like how they referred to other sports. this is probably the best sports science i've seen.
what brand of potato did you use to record this?
Your points are very good. CJ is an amazing athlete, and it's a shame they don't have Superstars anymore, as it would've been good to see him in action if he did it

And that is with screwed hand timing wich favors the runner. Johnson raned a 4.24 on electronic timing which is hard to do. Even world class sprinter Gatlin couldn't even crack a 4.3
that awkward moment when it freezes and you're left with a few seconds of silence.
@PowerSprinter I think they have a laser plane and when you brake it, the timer starts. So I don't think you need to add on the time for the starter's reaction. I believe the 4.24 he ran was electronic as well.
@WCCanuck true that. And the fact that in the 100 you run the first 30 meters just to build up to reach your top speed later and extend it as long as possible. Whereas in the 40 you jsut get the wheels spinning as quick as possible, thus limiting your long term top speed.
@CnCProductions1 this is seriously one of the funniest things ive read/seen/heard in a long time. kudos i actually LOL'd
@Peralasis take bolt's record run. In this run he took 4.64 seconds to get to 40m. But he had a reaction time of 0.15 seconds (combine clock starts after reaction).

Chris Johnson is doing East Carolina University of Greenville, North Carolina very well with his speed and elusiveness!
I watched that game. There were a few backups in there. Teams don't have 4th stringers active. They can only have 53 players active on gameday.
You're absolutely correct regarding him accelerating through that 30-40m but it was factored for in the margin of error of "± .04s." If you look at his 10m split between 40-50m it was only .03s faster than his split between 30-40m so by that point in the race he really isn't accelerating very much. If there were no margin of error, you'd be correct, but any discrepancy due to his acceleration over that split should fall well within that margin of error.
Damn CJ cant even run in a school zone when flashing. They might pull his ass over for speeding."The limit is 20 mph CJ." LOL
@PowerSprinter Chris Johnson ran a 4.24 in the 40....and it was electronically timed.
Proper track timing the sprinter starts average of .25 sec after the time starts. In 40 yd dash the time starts .25 sec AFTER the athlete starts running. This makes track times look a whole half a second slower than dash times.
i wish sports science could examine my ability to sit in front of the computer for more than 20 hours.
Jim Brown was one of the greatest football players that has ever lived.

Kinda like people do Wilt Chamberlain cuz he was just bigger than everyone else. I actually know a lot of people who do bring Jim Brown up quickly when discussing greatest RB's.
Cj is special especially on that team!!
I know. I've looked into this thoroughly and I actually base my opinions off of empirical evidence instead of just accepting what a TV personality says.

REVIS SPORTS SCIENCE PLEASE!
@bossofalltime ehh no, i heard his 40 split was 4.6
long legs have less accelaration, but better top speed
Which one? The combine 40? They start voluntarily so how could it involve reaction time?
I know this is an old video but may i ask you a few questions?
1: What cable provider do you have?
2: If you still have that tv what are your color settings on?
Thanks!!!
Their are a lot of fast people world wide. But the key is who with holds their top end speed the longest
I've only ever seen the videos posted online after. Always looked like they get themselves ready and start when they please and not when someone tells them to. Also, if they are using electronic "eyes" or timing gates, they don't start until the first one has been "broken" (i.e. first laser has been tripped) so it wouldn't matter if someone started them, the reaction time still wouldn't be timed.
@Rage23S well alot of a reciveivers or runnanbacks training is sprinting that includes just about all the football positions most football players in college and in high school do track
I hope he shits on Minnesotta this week, got em on my fantasy team. I have full confidence in this guy. Dudes the real deal
@bossofalltime ok so do you know CJ's spilts when he ran the 100m?
Just realized that Sport Science forgot to calculate in reaction time. Bolt ran a 4.3 WITH his reaction time. If you subtract that (.146), Bolt ran a 4.15s 40m.
wrong if you plot bolts 9.58 as a curve against time from the 10m splits you see that his 40 yard split is roughly 4.35s. take off his reaction time (based on the nature of the combine timing) and you have roughly the same (slightly lower) as johnsons time. then take blocks into consideration and you have about the same id say. an interesting comparison would be ato bolden, cos his start is ridiculous
They should do an episode for Barry Sanders.
6' 9" Stride?!?! THE FUCK?!?! THAT'S INSANE!
ok thats one and he still did it, they're all professionals but anyhow he still has more 80 yard runs than anyone ever in the history of the NFL
@gottawachit he's been clocked at 29 during the KC game though
what a smart lad you are
"What makes Him So Good" The Reporter Asks... Well.. HES FUCKING FAST!
To me Bolt is known more for his next gear than his initial acceleration. You watch his races and Bolt seems to just be starting to hit the after burners while the others are already at max their max.
Anyway, Chris Johnson has world class speed. He's taken a step back since signing that big contract, but that's pretty typical, for whatever reason, in the NFL today.
Chris Jonson NEVER had world class speed.
if only I could juke that well
He makes all the players he reviews seem alot better than they are.
pause the tv at his stride length...lol
@zislam159159 Ya a lot of people think they are going full speed the whole way but its not actually physically possible to sustain full sprint that long, theres more technique to sprinting than people think.
I'd like to see them do Barry Sanders. A true freak of nature.
I said over the last 6 weeks CJ leads in rushing. Not the whole season. It's a fact. The record prior to CJ was in fact, 2 career 80+ yard TD's for a career. It is CJJ's with 5 of them.That is also a fact. Now, how is it that I don't know what I'm talking about? lol
@bossofalltime I was praising you, haha. Good argument, no bullshit, no name-calling.
I love how they use tennis!!! So can I cut like a runningback too? Im pretty good at tennis lol.
I want all the top Olympic 100m sprinters to run the 40yrd dash just to see what the number would be.
btw a forty yrd dash is on your own go so bolt would probably be faster than cj if he was to go on his own count
Which pixel is chris Johnson?
lol he paused when it said 6' 9"
@dienglee you also have to understand that Olympic sprinters train just to run faster not to tackle or avoid being tackled
as gus johnson would say, he's got "running from the cop speed".
Y did it stop
@corbs0315 yeah no thats very probable think about that one
@icecru2 O sorry missed one detail.
yea we get he's fast
tell they got that tv at the salvation army
i wanna see lamichael james on sports science
@ExLiteW no, he used a camera
It'd be close for the first 40 yards . He runs with pads on daily so I'd love to see them race.
Whose did? There's no reaction in the NFL combine as it starts on movement. Bolt's time does include reaction because it's from a 100m dash and extrapolated. But his reaction is given so you can easily subtract it.
What do you mean?
Superman and Chuck Norris were both seen purchasing Chris Johnson underwear recently.
wow almost 24 mph in full pads!
@PowerSprinter which would mean tht chris johnson is even faster since the starter slows it down according to u
Wtf? Faster than Bolt? Holy shit!
How did 4 RB's go ahead of him in the draft? WTF were those teams thinking? Not to say those RB's aren't good, but seriously, watch his college highlights! How could anyone justify taking another RB ahead of him? Chris Johnson has the agility of Reggie Bush, the vision of Barry Sanders, and the speed of, well, Chris Johnson.

CJ always makes that last shift or movement to avoid hard collisions. He will last much longer than Adrian. It has been a joy to watch them both over the last 3 years though. I can tell you that!
@SteelersFan1734 You don't think Bolt was sprint as fast as he could during the 100 in the Olympics?
@shiron236 If you've seen Bolt's 30m & 40m split-times, he'd be comfortably ahead of CJ at 40yd
Explain?
no nfl player will beat any top class sprinter. in fact no sportsman apart from other sprinters will beat a top class sprinter because these guys devote everything in their lives to being faster, from what they eat to how they train
The NFL is a lot about acceleration. Usain Bolt has pure speed.
@MrPdiddy28 preach brother, preach...!!!!!!!!1 MILLION thumbs up
@elemix27 he really isnt, jackson top speed in pads was about 23, chris johnson was 28
i'll just leave it at this since you can't comprehend.
there was a reason usain bolt didnt want to race CJ in 40, 50, or 60 yards.
@adambulldogs34 bolt would probably be a wide receiver
not what I think, what I know. yeah they couldn't agree because of the conflict between pathetically short distances and distances that are long enough to determine true speed
@gottawachit lmaoooo
do a cam newton science
I had never seen sports science before. I didn't know it could suck so bad
his fuckin stride is the size of yao ming....this is why he's my fav player
@FrmTheTown 28 actually
Oh I didnt know that
@icecru2 The splt for Bolt are in METRES, 40yards is 36.6m (to round it up). I've been around Track all my life and whilst I have the greatest respect for the speed of the top Football players, they wouldn't touch a sub10 100m guy over 40yd
And also Bolt strides in the 100 instead of sprinting
Did you guys see that relay Chris Johnson did in "Shaq VS"? He wouldn't stand a chance against Bolt.
how does he do it :l
@zislam159159 40 yards is'nt used to measure top end speed. The average football play is between 4 and 5 seconds. The average football players runs 40 yards between 4 and 5 seconds. It's a measurement to see how fast someone will be on an average play.
@Uzerifth uh no, check the records buddy. There are NFL players that qualify for the olympics, break records, etc as referred to be @dienglee. :)
hat how people show it from their tv
so you have his 40 yard split? his split at 40 meters would of been 4.64, or about 4.5 at 40 yards
if thats what you think then fine, they said they couldnt agree on a distance
that dude is fast move over usain bolt Chris Johnson is the fastest person in the world now
@ThAtGuY97100 lol including the benches and free agency
imagine derick rose that would be a nightmare for defenders
@icecru2 Without bombarding the place with numbers, Bolt went through 40m in his 9.58 100m World Record in 4.64 and went 0.86 from 30-40m (11.63m/s) (40yd is 36.576m, so 6.576m and average speed of 11.63m/s takes 0.565.......30m split of 3.78 + 0.565 = 4.345 (4.35).

Bolt's raw 40yd would be 4.19-4.20 at the slowest
@theyoozernaim because they were higher rated, seen as more durable, and were in bigger conferences
Do you have any idea on what you are talking about? Bolt offical record time was 9.58 seconds in the 100 meter compared to Bob Hayes record of 10.06. Just under a half a second. Also, its not very hard to convert a 100 meter time into MPH. Also, Bolt may in fact could run a 4.19, but Bo Jackson ran a 4.12 and 4.18 within two days of each other at the 1986 Combine.
