MUSCLE PHYSIOLOGY

Detailed explanation-1: -Antagonistic Muscle is a muscle that opposes the action of another. For example, when the triceps oppose the contraction of the flexing biceps by relaxing, the triceps would be regarded as the antagonistic muscle to the biceps whereas the biceps, the agonist muscle.

Detailed explanation-2: -Opposing or antagonist muscles are the muscles that do the opposite of the muscle that is working. For example, when a person performs a bicep curl, the elbow flexes as the bicep shortens.

Detailed explanation-3: -As we’ve touched upon in our previous sections on both agonist muscles and antagonist muscles, the biceps and triceps function as both agonist and antagonist muscles.
