Closed kinetic chain exercises or closed chain exercises (CKC) are physical exercises performed where the hand (for arm movement) or foot (for leg movement) is fixed in space and cannot move. The extremity remains in constant contact with the immobile surface, usually the ground or the base of a machine.
Kinetic chain exercises are categorized into two types: open and closed. Open kinetic chain exercises are movements where the hand or foot is free to move and not in contact with a surface (like a ...
In a chain reaction, positive feedback leads to a self-amplifying chain of events. Chain reactions are one way that systems which are not in thermodynamic equilibrium can release energy or increase entropy in order to reach a state of higher entropy. For example, a system may not be able to reach a lower energy state by releasing energy into ...
The kinetic chain is key for preventing injuring and upping performance. Trainers explain it and the best kinetic chain exercises to add to your routine.
In the overhead throwing motion the body is a kinetic chain, and the efficiency of the kinetic chain determines the quality of the throw (velocity and accuracy of the projectile). The thrower uses muscle segments throughout the whole body to transfer potential energy from the lower extremities to the upper extremities where it is then ...
The opposite of OKC are closed kinetic chain exercises (CKC). Both are effective for strengthening and rehabilitation objectives. [1] Closed-chain exercises tend to offer more "functional" athletic benefits because of their ability to recruit more muscle groups and require additional skeletal stabilization. [2]
In chain-growth polymerization the propagation step is the addition of a monomer to the growing chain. The word kinetic is added to chain length in order to distinguish the number of reaction steps in the kinetic chain from the number of monomers in the final macromolecule, a quantity named the degree of polymerization. In fact the kinetic ...
A model of the human skeleton as a kinematic chain allows positioning using forward and inverse kinematics. In mechanical engineering, a kinematic chain is an assembly of rigid bodies connected by joints to provide constrained motion that is the mathematical model for a mechanical system. [1]
