Answer :
Using the theories of muscles, we got that Coactivation is a phenomenon in which contraction of an agonist muscle leads to provide joint stability in the antagonist muscle.
Muscle coactivation occurs when the agonist and the antagonist muscles (or synergist muscles) surrounding the joint contract simultaneously to provide joint stability. It is also known as the muscle contraction, since two muscle groups are contracting at same time.
The phenomenon of the agonist-antagonist muscle coactivation is discussed with respect to its consequences for the movement mechanics (such as the increasing joint apparent stiffness, facilitating faster movements, and effects on the action stability), implication for movement optimization, and involvement of the different neurophysiological structures.
Hence, Coactivation is a phenomenon in which contraction of an agonist muscle leads to provide joint stability in the antagonist muscle.
