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
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.
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.
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
What is the function of reactor muscles in males?
Reactor muscles are the same for male and female. A reactor muscle are 2 muscles that do the opposite function (Ex. Bicep and triceps). To answer your question, the purpose of reactor muscles is to have a muscle that contracts and the other muscle stabilize. There are other terms I could use such as the muscle that is contracting is performing an concentric contraction (Contracting while shortening [Performing a bicep curl with a dumbbell]) and the muscle that is stabilizing is performing an eccentric contraction (Contracting while lengthening [Ex. Lowering a dumbbell with a bicep curl bar]). The reason this is important is because without the stabilizing muscle, also called an antagonist muscle, you would not have smooth controlled movement anywhere in your body. It would not be a good engineer and we would not be able to move are arms without looking weird. I hope this helps.
Which muscles does the bicep curl he lp?
The bicep curl obviously helps the Bicep but it also helps you triceps as you pull your fist towards you your are contracting your bicept and relaxing your tricep
What muscle contraction is involved in a bicep curl?
i did sports science but cant forget the terms properly.. however there are two parts to bicep curls, the up and down. durin the uplifting of a weight, the bicep is the main muscle working, whilst the tricep is assisting, this is opposite for downwards phase.
What muscles does the preacher curl work?
The preacher curl in my opinion is the best bicep exercise.It is better than barbell curl because barbell curl works bicep brachii but it does not give enough work to brachialis muscle.Preacher curl works both Bicep brachii and brachialis.First Mr.Olympia Larry "The legend"Scott used to do Preacher curl and he developed 20' inch Arm.
