Which is the agonist muscle and which is the antagonist muscle in performing a bicep curl?
Agonist is bicep and other elbow flexors antagonist are all the elbow extensors ie triceps
What is the opposite of a antagonist muscle?
The opposite of an antagonist muscle is a protagonist muscle, often referred to as an agonist. The agonist muscle is the primary muscle responsible for performing a specific movement, while the antagonist muscle opposes that movement. For example, during a bicep curl, the biceps act as the agonist, and the triceps serve as the antagonist.
Why are antagonistic muscles important?
Muscles cannot push, they can only pull which means they work in pairs in order to move, this is known as antagonistic pairs. For example with a bicep curl you have the agonist/ prime mover (Bicep) and the antagonist/ Opposing muscle group (Triceps). As the agonist contracts it pulls the antagonist which relaxes.
What is a torn bicep muscle?
A torn bicep muscle can usually occur when your bicep muscle is fully extended and under too much pressure. Weight lifters often get a torn bicep muscle when doing the preacher curl. The preacher curl can really strain the bicep muscle, and lead to a torn bicep muscle if you are lifting to much weight or have not warmed up correctly. Your bicep is a muscle on your arm. it is the muscle that you usually flex when trying to show off your srength. Most torn bicep muscle injuries occur when the arm is fully extended and the lifter is just about to pull the weight back up. When you get a torn bicep muscle you will feel an immediate sharp pain in your bicep near your elbow, followed by bicep muscle weakness and stiffness and eventaully bruising.
What muscles are worked during a cross body bicep curl exercise?
During a cross body bicep curl exercise, the biceps brachii muscle is primarily worked.
Is concentric isotonic contraction is defined as tension developing in the muscle as it shorten?
That is correct, the muscle shortens as it contracts. E.g. A bicep curl, the bicep muscle as you lift the wight up is Isotonic contraction. :)
What is the antagonist muscle when performing leg curl?
The triceps lengthens when the biceps contracts, making the triceps the antagonist.
What muscles get worked in an arm curl?
When you preform an arm curl, you use your bicep muscle. it all depends on how you curl. If you curl straight up or do a twisting motion while curling. You use your shoulder and bicep and maybe a small portion of the pectoral muscle where it meets the shoulder.
Is a bicep curl an isotonic or isometric exercise?
A bicep curl is an isotonic exercise.
What is an example of an isotonic contraction?
An Isotonic contraction is when a muscle becomes longer or shorter to produce force and therefore an example is a bicep curl. During the downward phase your muscle (bicep) lengthens and during the upward phase your muscle (bicep) shortens.
Difference between agonist and antagonist?
Agonist works with the muscles, and the antagonist is the muscle working against it in a contraction. i.e. Bicep curl, the agonist is the Biceps brachii and the antagonist muscle is the triceps brachii.The word agonist means "producing an action" - an antagonist opposes that action. In medicine, an agonist binds to a receptor site and causes a response, often imitating the natural body reaction. An antagonist acts against this drug and blocks the response. for examples ramiels small balls and pubic hair
A sporting example of a concentric movement?
Hahahahahahahahahah A Divinaaaaaaaa
