2012) stretching (pectoralis major muscle) on agonist muscle
activity (latissimus dorsi and biceps brachii) were investigated.
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.
When trying to accelerate sub-maximal weights, manifested power-rates remain constant with increasing speeds because: (1) they are partly counteracted and balanced by forces developed by contractions of antagonist muscles; and/or (2) antagonist muscles do not immediately contract (and keep observed power levels constant), but the contractile power-rates of agonist muscles
is held in check when they are employed to forcibly accelerate sub-maximal weight loads.
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).
This resistance against the contraction of the agonist muscle
is associated with reflex inhibition of the antagonist muscle, that is, relaxation.
One method is the agonist-antagonist paired set (PS) that consists of paired sets between exercises for an agonist muscle
group followed an exercise for the antagonist muscle group with or without limited rest interval length (16).
Briefly, in the MVC task, the maximum value of EMG (EMGmax) in each agonist muscle
was determined over a 500 ms window centered on the time at which peak torque was attained.
Therefore, an increase in the agonist muscle
activity is required in order to achieve force outputs equivalent to those of the pre-fatigue trials.
Resting your hands or body on the floor terminates or diminishes the agonist muscle
Therefore, the purpose of this study was to investigate the acute effects of antagonist contract-relax PNF stretching on agonist muscle
activation and strength performance.
When a stretch reflex excites one muscle it simultaneously inhibits the agonist muscles
, which is called reciprocal inhibition this takes place due to reciprocal innervation.
The decreased activation of the extensor carpi radialis is in accordance with the pain adaptation model (24) that predicts a reduced activity of agonist muscles
in the presence of chronic pain.
