Motor Programmes..

I have looked for open and closed loop movement control and cannot find anything and never heard of it before.

The closest thing I can think of which maybe similar is open and closed kinetic chain movements.

An open kinetic chain (OKC) movement is where the distal end of a segment is free to move like a leg extension on a machine. The foot is able to move freely which is the bottom segment/end part of segment.

A closed kinetic chain (CKC) movement is where the distal end of a segment is rigid/fixed like a squat. the foot is fixed to the floor and the rest of the body moves from this position.

Other examples of OKC's are the lat pull down compared to a CKC chin up. With CKC the movement occurs around a fixed point with all the rest of body segments moving while a OKC has one or tweo segments freely moveable with the rest of the body segment fixed.

OKC tend to be single joint actions working few muscles. There are obviously exceptions such as bench press / lat pull down. But generally of the lower limb ther are smaller movments.

CKC tend to be multi jointed movments requiring a lot of muscle action such as squating, dead lifting.

There is still controversy over cycling as an OKC or CKC. Some say it is CKC as the feet (distal end of segment) are fixed while others say OKC as the fixed points are moveable. The difference is that it can be classified as both. The dital end segment is fixed but moveable but only moveable in one movement plane (sagittal around the frontal axis). Then there is the difference of seated riding and standing riding.

Walking is OKC as both feet are freely moveable.

I think this is what you are looking for. If not , disreguard all of this!!

my favourite is 'TOP GEAR'

sorry couldn't resist it! :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

A good book to look at is by magil 'Motor Learnig Concepts' and Schmidt ' Motor Learning and Performance.'

Both have good information on this area.
