What muscle is the antagonist when performing a push up?

For a pushup, the antagonist muscles are your back muscles (their “pull” motion is the opposite of your chest muscles’ “push”); your biceps (they oppose the motion of your triceps); and your rear deltoids, or the back-facing fibers of your shoulder muscles, which oppose the motion of the anterior deltoids.

Which muscles are antagonists?

In an antagonistic muscle pair, as one muscle contracts, the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

Antagonistic muscle pairs.

Biceps Triceps
Gastrocnemius Tibialis anterior
Pectorals Latissimus dorsi

What muscles are used when performing a push-up?

In the standard pushup, the following muscles are targeted:

  • chest muscles, or pectorals.
  • shoulders, or deltoids.
  • back of your arms, or triceps.
  • abdominals.
  • the “wing” muscles directly under your armpit, called the serratus anterior.

What is the agonist primary mover muscle in a pushup?

So the agonist muscles for a push-up are the pectoralis major, biceps (shoulder flexion), triceps (elbow extension), and serratus anterior, pec minor (scapular protraction). They are working concentrically during the up phase, and then eccentrically during the down phase—they are the agonists for both phases!

Which muscles are agonist and antagonist?

The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

Antagonistic muscle pairs.

Antagonistic pair Latissimus dorsi; deltoid
Movements produced Adduction; abduction
Sport example Golf swing; breaststroke arms

What are antagonistic muscles short answer?

In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.

Antagonistic muscle pairs.

Biceps Triceps

What is an agonist what is an antagonist?

An agonist is a drug that binds to the receptor, producing a similar response to the intended chemical and receptor. Whereas an antagonist is a drug that binds to the receptor either on the primary site, or on another site, which all together stops the receptor from producing a response.

What type of contraction is a push-up?

Isotonic contractions

Concentric contractions involve the muscle shortening under tension, and it is the most common form of muscular contraction. For example, the biceps concentrically contract during the upward phase of a bicep curl, or in the triceps during the upward phase of a push-up.

What is latissimus dorsi muscle?

Introduction. The latissimus dorsi muscle is a broad, flat muscle that occupies the majority of the lower posterior thorax. The muscle’s primary function is of the upper extremity but is also considered to be a respiratory accessory muscle.

Is the biceps Brachii an antagonist?

In this example, biceps brachii is the agonist or prime mover. Triceps brachii is the antagonist and brachialis is a synergist with biceps brachii.

What are antagonistic muscles give examples?

Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonistic pair is the biceps and triceps; to contract, the triceps relaxes while the biceps contracts to lift the arm.

What are antagonistic muscles explain with examples?

Antagonistic Muscle (biology definition): 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.
