    Are the results from this study much of a surprise???
    They recorded barefoot plantar pressure readings the day before a marathon, and then within an hour afterwards with an Emed system.
    Most people will be a bit proppy after running a marathon and will likely to be tending to be somewhat apropulsive- particularly if they are barefoot after being in running shoes.
    'The increased peak pressure under the metatarsal heads after the race indicates a load shift from the toes to the metatarsal heads' - I know thats how I walked after my half marathons... mainly to take some load off the calves- blistered toes would not help either.
    Relating this to met stress fractures is probably drawing a long bow...

    Craig T;

    tight hamstrings and achilles after the race probably played into this as well since most walk a little w/ knee flexed adn this can shift CoP to the forefoot more than the heels.

    All valid points above adn I agree completely. Interesting information, but of little value in its lack of specificity.

    I hope you are well in the middle east? All your tech equipment running well too?

    cheers

    I think the key thing here is (and I heard CP talk about it often), is the effect of fatigue on foot function when all the research and our clinical testing is done on "fresh" research subjects and patents.

    What about fatigue of the small intrinsics such as the lumbricals and interossei. being smaller mucles, may be more susceptable to fatigue and therefore unable to adequately stabilise the digits, leading to less flexion of the toes, therefore less area under which GRFs can act under the forefoot?

    I have seen it suggested (without data), that the cause of plantar fasciitis is fatigue of the plantar intrinsic muscles .... interesting hypothesis.

    See this thread:
    Fatigue of the plantar intrinsic foot muscles increases navicular drop

    Cheers Craig! :drinks

    Interesting thread, although I'm struggling with the concept of getting the subject to do a voluntary isometric abductor hallucius contracture, and although it should be the most appropriate intrinsic muscle with regards to arch height, I wonder if measuring the navicular height really identifies the role of the abductor hallucius in arch height. isthere a better solution though? Perhaps force required under the hallux to activate windlass (i.e. modified Jacks test?). Dont know....

    This article does stimulate an interesting idea. Has anyone done any studies looking at running a marathon/half marathon with an Fscan/PEDAR system in the shoes to se what happens to the foot during over such a prolonged time of excessive activity?

    And in light of research such as this, and the foot injuries that I've seen sustained after a marathon, I do raise the point, liek ballet, should we be encouraging such outrageous requests of our bodies? :eek: (Obviously I don't run....)
