I'm wondering if some of readers of the list have had some experience with
the problem of leg circulation while paddling....

We have found over the years that many people who think they have problems
due to sitting still or having an "uncomfortable" seat actually have a very
different problem.  When we slouch we let our pelvis go flat so that the
connection with the lower spine becomes a tight turn constricting nerves,
etc.  This leads to feelings of general leg pain and pins and needles which
become alleviated by stretching, etc and are thus often misdiagnosed as a
seat that pinches nerves, etc or not moving the limbs.

This also leads to long term back injury!  - long term lower back injury is
the most common reason recreational paddlers leave our sport

The solution; Firstly your seat must be higher than your feet - yes this
does make things less stable but tough) a minimum of 5 cm is absolutely
essential, 10 is much better.  Secondly the base of your seat should rise as
it goes aft (most seats have a dip in the middle which unfortunately
reinforces slouching)  Finally you need to make a deliberate action of
tilting your pelvis up as you first sit in your kayak and each time you
start paddling again after a break.

Tight hamstrings will gradually pull the pelvis flat - work on stretching
your hamstrings as part of your paddling routine - also make a habit of
regularly kissing your fore deck to stretch things out as you paddle.

How do you know if this is a problem?

If you can tilt your pelvis up whilst sitting in the "normal" paddling
position then yes you have an aft tilted pelvis and should do something to
help yourself.

Secondly to test it on the water, when you get a feeling of leg pain or pins
and needles, etc.  Lean forward and kiss the deck, specifically stretching
the hamstrings for at least 10 seconds then sit back upright making sure to
give the pelvis a quick jiggle and straighten.  There should be immediate
relief

Happy paddling
