Minimalist Running Does NOT Increase Arch Strength

    Thanks NewsBot for the update on these issues. Look forward to more research on these areas.

    That Amby Burfoot blog is quite interesting...

    I suspected this - putting aside the fact that I certainly wouldn't run in some types or running shoes that are on the market... look forward to more.

    Interesting... I would have suspected it would be more economical - then again, I don't know what shoe they used for this (some variable factors involved). Look forward to more research here as well.

    Interesting results... "they performed several submax running tests with a lower heart rate and lower oxygen consumption".

    So do I (I think :confused:)... but this choice of running is surely not really known by that term ("evolutionary running") :eek:. Why can't I be seen as just a runner? :rolleyes:

    Anyways, research to look forward to in the future.

    Whilst I don't find these results at all surprising, as we have all discussed this issue at length previously. I do think we need to question the validity of the measure they have used. Arch height index, or the modified arch rigidity index seem to be more a measure the the stiffness of the passive structures within the foot such as the plantar fascia and spring ligaments. Given that the plantar intrinsic foot muscles display only minimal amounts of activity in static bipedal stance, it appears somewhat redundant to use a measure of foot posture in this position to address a hypothesis based around progressive strengthening of these muscles. These foot measures were never going to change from 6 months of running in these minimalist shoes unless the shoes could also miraculously increase the stiffness of the plantar fascia. :confused:

    Anyway, I'm at ACSM right now, so I guess I'll have to ask them that question tomorrow....
