During a biceps curl, the opposing muscle group—the antagonist—is the triceps.
What is the antagonist in a dumbell curl?
When you do a dumbbell curl, your triceps are the antagonists, for example. Their primary job is to extend the elbow, but they relax enough to allow your biceps (i.e., the “agonists”) to flex your elbow and lift the weight while still producing enough opposing force to help keep the movement controlled.
What is the antagonist muscle in a bicep curl?
Muscles contract to move our bones by pulling on them. … For example, when you perform a bicep curl the biceps will be the agonist as it contracts to produce the movement, while the triceps will be the antagonist as it relaxes to allow the movement to occur.
Which muscle is contracted in a dumbbell curl?
Curls work the biceps muscles at the front of the upper arm, and also the muscles of the lower arm—the brachialis and brachioradialis.
What two muscles are antagonistic?
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.
Is the biceps brachii an antagonist?
Flexing of the forearm by the biceps brachii: The biceps brachii is the agonist, or primer mover, responsible for flexing the forearm. The triceps brachii (not shown) acts as the antagonist.
What muscles work in a bicep curl?
Bicep curls isolate the body movement of elbow flexion, or rather bending of the arm at the elbow. It targets the specific muscles located at the front of your arms called; biceps brachii, brachialis and brachioradialis.
What are antagonistic muscles pairs?
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.
What is an example of an antagonist muscle?
The most common example of antagonistic muscles are the biceps and the triceps. As the agonist muscle contracts, the antagonist relaxes, helping to manage and regulate the movement of the former.
What are the bicep muscles?
The biceps is a large muscle situated on the front of the upper arm between the shoulder and the elbow. Also known by the Latin name biceps brachii (meaning “two-headed muscle of the arm”), the muscle’s primary function is to flex the elbow and rotate the forearm.
What is the antagonist muscle in a lunge?
The quadriceps are the agonist and the hamstrings are now the antagonist.
What is the antagonist of the tibialis anterior?
It is innervated by the deep peroneal nerve and acts as both an antagonist and a synergist of the tibialis posterior. However, the most accurate antagonist of the tibialis anterior is the peroneus longus.
