Too many injuries

<p>Naholo? More from the "they all look the same" shelf.</p>

<p>That's an astonishingly astute call first thing in the morning.</p>
<p> </p>
<p>Naholo has a rats tail, Nadolo has the Peter Garrett look. Both can run fast. Easy mistake to make though.</p> -

<p>I remember reading an article earlier this year after Naholo sent that Auckland fullback flying, someone measured the impact as being like being hit by a car. When he marked Jamie Roberts in the midfield the year before it as 125kg against 110kg.....just bloody monsters playing the game nowadays.</p>

<p>Kudos to Mike Catt and other comparative midgets at least trying their best to stop Jonah back in the day.</p>

<p>TeWaio I agree with some of that but it doesn't explain how short ( and in some cases not particularly stocky ) Olympic weightlifters can snatch ( haha, snatch ) many times their weight overhead. Sure they have the genetics but <strong>so much of that is down to training and strengthening those ligaments.</strong></p>

I agree....as I said:<br>

<p>Olympic weightlifting is a little different as the biomechanics mean the full weight of the bar is only being supported in "strong" positions, i.e. at the end with arms full locked, or in the drive phase where legs/core are pushing the hips forward to get it accelerating upwards, or in the catch where the bar is sitting on the collarbone. So in a successful lift at no point is there huge force on a ligament or joint from a funny angle. Whereas in rugby the force/loading could come from nearly any random direction at any time. </p> -

<p>Which I guess explains why broken bones sometimes happens if they fuck up a lift.</p> -

<p>Yep, they're lifting so much more than a bone/joint/ligament is able to bear in the "wrong" position that you can get some horrendous injuries. Fortunately they're pretty rare though. YouTube "weight lifting fails" if you're strong of stomach. </p>

<p>I do the odd power clean every now and again and would hate to fuck it up. Whilst strength is obviously important technique and co-ordination would be more so for those Olympic guys I'd imagine.</p> -

Of course it is. Headgear means lower deceleration: skull starts slowing down from when the foam part initially hits something immovable, and is spread out over longer distance as the foam deforms on impact. So change in velocity happens over a longer time. <br><br>
Lower deceleration of the skull means lower deceleration of the fluid and brain inside, which means the brain hits the skull with less force, or maybe not at all.<br><br>
Think of a car (skull) hitting a wall (opposition 2nd 5's knee) with no crumple zone - the person (brain) inside turns to mush. Same car with a well-engineered crumple zone (headgear); impact between person and front of car is less.</p></blockquote>

Sorry, virtually nothing.<br><br>
Your comparison with a "well-engineered crumple zone" and headgear that has a maximum thickness of 10mm and then might only compress as little as 2 to 3mm, is a massive stretch.<br><br>
Considering the considerable g forces involved, a 2 or 3mm give IS virtually nothing. -

<p>yep, wore headgear to avoid cuts and damaging my beautiful ears when playing front row. Didn't see it offering anything to ward against concussion.</p>

Right, but its not nothing, which you said. That's the point I was trying to make with the crumple zone analogy.</p>
