We observed reduced antagonist muscle
activation in our study, which is consistent with neural adaptations and might also include changes in the temporal sequence or frequency of muscle activation (Ross and Leveritt, 2001).
Flexibility training programs are not primarily focused on maximally increasing a participant's muscular strength; however, in accordance with Sherrington's Law, there should be an increase in muscular strength of the agonist muscle in order for there to be an increase in the length of the antagonist muscle
22) that static stretching of the antagonist musculature would improve performance first, by increasing the neural drive to the agonist muscle, second, by decreasing neural drive to the antagonist muscle
; and third, by reducing antagonist muscle
stiffness and opposing forces or a combination of these factors.
The purpose of this other restriction may not be to also ensure that forces do not eventually exceed a safe upper limit or to prevent joints from imminent injury, but perhaps to gain a preemptive "head start" on averting the possibility that a weaker antagonist muscle
could be injured if and when it has to contract.
5 units is injected into the overacting antagonist muscle
by grasping the muscle tendon with fixation forceps.
Applying mechanical vibration to a muscle tendon in relaxed human subjects induces either a contraction of the vibrated muscle or contraction of the antagonist muscle

fatigue on knee extension torque, Pflugers Archiv: European Journal of Physiology 446(6): 735-741.
2] during HTC increased more than during ULC because HTS could enhance muscle activity sufficiently by using electrically stimulated eccentric antagonist muscle
contractions as a resistance to voluntary agonist muscle contractions (as a substitute for an external braking force).
Regarding the posterior deltoid, the poor correlation observed indicates that, although there is a relationship between the force production in the bench press and the antagonist coactivation of the posterior deltoid, this association is not strong, at least when only one antagonist muscle
2) to be the evidence for significant abnormalities in reciprocal relationships between the crural muscles and enhancement of co-contraction in the antagonist muscles
Concurrently, the triceps, an antagonist muscle
to the biceps, is inhibited by intemeurons activated by the same reflex and the triceps muscle relaxes.
The implication of this finding is that, during in vivo exercise, appropriate coactivation and co-ordination around the joint may be maintained, despite exercise induced fatigue of an antagonist muscle
Acute effect on power output of alternating an agonist and antagonist muscle
exercise during complex training.
By electrically stimulating the scapholunate ligament (SLL) during wrist flexion-extension and radioulnar deviation, the immediate reflex response was consistently observed in the antagonist muscle
for each position (joint protection), followed by coactivation (global stability).
These moments must be controlled by the antagonist muscle
group (quadriceps at heel strike, hamstrings at midstance) to provide stability to the knee.
