James Cracknell – Wear a Helmet Video.

Thought I’d share that with you.

I CALL TROLL!!!!

Strong message!

Good stuff. Even TJ wears a helmet in real life you know!

I think its a good message but did he have to do it in Bear Ghyrll’s voice?

Not sure what he was like before.. Just watching him doing the Yukon arctic race on discovery.

Good stuff. Even TJ wears a helmet in real life you know! when appropriate.

However you actually need to look into this a little closer. Cracknell got a diffuse axonal injury – the type of injury associated with rotation of the brain which is the type of injury where any evidence for helemets reducing it is poor and there is some evidence helmets exacerbate diffuse axon injury

I thought it was a contrecoup injury – the front of his brain basically crashed into the inside of his skull when he hit the road. That being the case, his helmet probably did make a huge difference by diffusing some of the energy of the impact as it broke.

If it was a contrecoup injury then you would be right to say the helmet probably reduced the severity.

I thought it was a diffuse axonal injury but only rather duff reference to it available that I can find

Rounddddddd 8.

The video referred to in the OP supports my version 😉

Knock out to me in the closing stages of the 7th I reckon….

nah he’s on the ropes

1….

concussion possibly.

Dammed annoying that I looked at this before and found good references, now cant find any. Must be mistaken Humpf

Cracknell was hit from behind and reportedly fractured his skull at the back of his head. But his injury is actually in the front of his brain, because his brain shot forward when his helmeted head hit the road. He sustained a contrecoup injury to his frontal lobe, with bleeding and swelling. …..

Luckily for Cracknell he had just bought a new Alpina bike helmet, which is designed so that it fits low on the back of the head. That design helped Cracknell. Doctors said that the helmet, which split in two when Cracknell hit the ground, saved his life.

Just like TJ I always consider whether I’m more likely to suffer a contrecoup or axonal injury before going out for a ride, doesn’t everybody?

3….

dinnae hit a man when he is down druidh 🙁

4….

I don’t think he’s getting back up after this one.

5…

dinnae hit a man when he is down druidh

If ye kick him on the head (and he has a helmet on) you could give him one of thae rotational injuries

Tj, an opinion on everything is one thing but professing knowledge… you are more a jack of all trades, master of none!

Could it be a bit of both. Contrecoup and DAI?

6…

He really is running out of time.

I should have checked before posting. I did see it before I am sure but dunno what happened cos it ain’t out there now.

SBZ – its normally a mix if injuries but that bit druidh posts is clear that its mainly if not solely a contracoup in which case what I said does not apply

7….

Is that a (unbranded) towel I see before me?

8…

I wouldnt be giving up that easily TJ. Maybe throw a DIA/coup/contrcoup definition counterattack combo.

had a search for useful ammo – nowt. Half a daily wail quote. useless

Too late SBZ.

I think we should store this one away in the STW vault.

It was worth a standing 8 count at most. But you did well to make him quit Druidh.

Contrcoup – denoting an injury, as to the brain, occurring at a site opposite to the point of impact. So – is the impact the mirror on the back of his head or from his head hitting the road?

Coup – denoting an injury, as to the brain, occurring at the point of impact. Or is it this one?

Diffuse Axonal Injury (DAI),
a type of brain injury caused by shearing forces that occur between different parts of the brain as a result of rotational acceleration. Pretty hard to get from being skelped hard on the back fo the head to headbutting the ground without a bit of rotation… Common site of injury – frontal lobe.

Helmet probably saved him from having bits of skull embedded in his brain, but it probably didnt help much with what was going on inside his skull.

its a a contracoup from the description. the impact (coup) is the blow to the back of the head, the contra coup is when the head stops moving and the brain hits the inside of he skull. the helmet would have taken some of the energy in all probability

druidh – you want the full thousand post debate? I think on that one I proved be a great mass debater

As long as you obey the 3 point system you will be fine, kids.
