Three types of muscle contractions are: Concentric, Eccentric and Isometric.
Concentric: This is a result of muscles shortening and which generates force. An example would be the elbow joint. The Bicep Brachii contracts when the joint moves from straight to fully flexed.
Eccentric: This occurs when the muscles lengthens as it contracts because the opposing force is greater than the force generated by the muscle. For example the hamstring contracts eccentrically when kicking a football to help decelerate the motion of the lower limb as the quadriceps muscles contract concentrically.
Isometric: The muscle without changing length generates force. This means that you hold your muscles in a set position with force pulling or pushing equally and

    As i hold the bar at the top , is the isometric contraction. the muscle is strongest in the eccentric phase. There are two constituents that are associated with the muscle - the series elastic constituent and the parallel elastic constituent. The series elastic constituent is the tendon that is binded to the given muscle, which stores energy on its own but procures a considerable portion of its applied energy from the contracting muscle. The parallel elastic constituent is almost everything else except the primarily ligaments and fascia.…

The result of this change is impairment of voluntary movement creating symptoms of such as akinesia and bradykinesia. The next part of the motor loop to be affected is the increase inhibition pedunculopontine nucleus causing disinhibition of the reticulospinal tract causing rigidity of postural and girdle muscles. The last area of the motor circuit to be affected is the increase inhibition in the midbrain locomotor area causing decrease signals from the reticular formation to the spinal steeping pattern generators causing loss of automatic gait.…

    What Is Meant By Agonist In Muscle Pairs

    What is meant by “agonist and antagonist muscle pairs”? Give an example What is meant by agonist in muscle pairs is that it does the majority of the workload in an exercise and is considered the prime mover (primarily responsible for movement). The antagonist in respect to the agonist counteracts. The antagonist helps allow the agonist to perform a task. An example could be the biceps brachii contracts when doing elbow flexion.…
