i seem to recall that they did a test soaking old style balls and modern balls in water and the difference in weight wasn't as much as they had predicted - and that the velocity gap was greater than the weight gap - the modern balls still can hurt when you head them as I found out when I helped out in my sons football training about 10 years ago. -- SW6.doc

In reply to: Hg 's message, "I need to read up on this, because although they might be correct in saying in saying that the new balls could worse, as force = mass x acceleration..it doesn’t negate the fact that players don’t get knocked out by the ball like they used too. Are they saying it’s more to do with repetition, as I find it very hard to believe that new balls hit harder. A lobbed ball will rely more on gravity for its downward force, which would be affected more by weight , than aerodynamics" on Tuesday, December 10, 02:57:30pm

There’s so many variables for this. Did they use a machine to test this, or did they do it using humans. And if it were humans did they use old and new boots, as older boots, although heavier and slower, would give the ball more force upon impact, than the new light weight boots.

- I can't answer your questions re methodology and it may be that some of the findings can be challenged - but as said above, don't think the findings can be dismissed out of hand . In terms of boots - again I dunno but when I was growing up it was mainly the likes of Bobby C and Peter Lorimer who would regularly score from o/s the box - it seems to me that goals from distance much more commonplace now. - but that could be dodgy memory anecdotal evidence on my part.

  - I’m disputing that heading a ball can make you more susceptible to dementia. Just find it really hard that the new balls can t you with as much force. Those old balls in the wet were like medics balls. (NT) -- Hg, Tuesday, December 10, 03:52:39pm (NoHost/31.94.34.14)
    - Sorry phone playing up. I’m not disputing, that should read. (NT) -- Hg, Tuesday, December 10, 03:55:08pm (NoHost/31.94.34.14)
