1. An open chain allows freedom or at least a certain degree of freedom of movement (according to resistance).
2. A closed chain does not allow freedom of movement at the end (or if it allows it, it is with many restrictions) so we understand that:
1. Open Chain = last element of the chain, free.
2. Chain Closed = last element of the chain, fixed.
What are the kinetic chains?
THE CLOSED CHAIN:
We will define it as the action performed with a limb, in a situation in which the last element of the bone chain is fixed. A clear example is a pull-up in which the hands are fixed while we bring the entire body system closer to them. Closed chains also appear (depending on the author) when we have to overcome a GREAT resistance that prevents the total freedom of this movement. For example, if we were pushing a heavy weight above us with our upper limbs, some would consider it a "semi" closed or even "semi" open chain.
THE OPEN CHAIN:
We will define it as the action performed with a limb, in a situation in which the last element of the bone chain is free. The distal segment can move freely. In the figure the feet are in a situation in which, unless the load exceeds the possibilities of movement, we will be able to extend the knees and produce the movement in our last most distal bone piece (the feet).
