No need to apologize Adam , as the best threads often included twists and turns in subject matter . With regard to your very reasonable question ...

If you start to consider the centrifugal effect on venous return , then perhaps it might be easier to better help with venous reflux during gait . ...

Hi Adam , The site moderator suggested that a physiologist might be able to help progress the thread further , so I was happy to...

Many thanks Ton . Re the repeated and slightly embarrassing spelling error ( I am too old to be very embarrassed ) , could I pass that off as the...

Many thanks for the above . During gait on a running track ,the foot undergoes periods of rapid acceleration ,even more rapid deceleration and...

Here is an abstract of a very recent paper which looks a calf muscle pump function (below) . Pump function is looked at under 3 conditions but...

Hi Allan I have started a new thread on the subject introduced above under " Centripedal forces and the calf muscle pump " . Hope that is...

Actually Allan you might just be the man for this . I get the impression you like to think about biomechanics , just as I do myself , and I have...

Allan Can you use changes in C7 position as representative of hip movement within the context of the golf swing ? With regard to the...

"at least some of angular momentum generated in the kicking leg seems likely to be generated by the vertical deceleration of the pelvis cause by...

Allan We are firmly off piste here and it would be astonishing if the vertical acceleration and deceleration of the pelvis were key to...

Any thoughts on the above Ton ? Gerry

Adding to the present thread it should be noted that although vertical acceleration of the pelvis produces angular acceleration of swinging limbs so...

Away from gait but still talking about angular acceleration of swinging appendages through the linear , vertical acceleration of the pelvis , this...

To put it in a nutshell , gait is not just about using your limbs etc to propel you forwards . You must first be able to get your limbs into the...

Hi Allan Leaving aside the "arm component " the thread is about accelerating the swing leg and not advancing the COM forwards. The arm...

Hi Ton , Many thanks for joining the discussion and for adding a bit of mathematical elegance to proceedings . However , things may be...

I think it is likely that vertical movement of the pelvis , produced by forces generated through the stance leg , will help produce angular...

Hi Zia I think I might have read up a bit more on Newton . However , the main thrust of the thread is this question . Does vertical...

Hi Zia Thank you for responding . So would I be correct in assuming that you agree that vertical acceleration of the pelvis , caused by...
