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.

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 muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
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.
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.
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 angonist muscle and which is the antagonist muscle in a bicep curl?
The agonist (not angonist) muscle are the Biceps Brachii and the Brachioradialis and the antagonist is the Triceps Brachii.
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 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.
Name the fixator muscles in a bicep curl?
since the bicep curl is a flexion of the forearm at the elbow, the biceps brachii and brachialis are mainly used, especially in the supinated position. a prone bicep curl uses brachialis and brachioradialis more. the biceps brachii function is much less, since it is also a forearm supinator, so it is deactivated in the prone position.the triceps brachii are the antagonistic muscle group are not not involved in the bicep curl. the triceps extend the forearm at the elbow.
What is the prime mover of a bicep curl?
the bicep contracts in a concentric contraction which means the muscles has shortened. remember muscles can only pull they can not push. also the bicep curl can be described as elbow flexion and when the weight is lowered is called elbow extention. hope it helps
What are agonistic pairs?
Pairs of muscles which work in a relationship, where both can support and oppose each other. The best and easiest example is the bicep and tricep. When the bicep is contracted the tricep is usually relaxed and visa versa. Think of it like a bicep curl. When you lift the dumbbell your bicep is contracting in the concentric contraction, but is still contracting on the way down, just on an eccentric contraction (i.e. acting as a brake). The whole time your tricep is relaxed. However when a tricep curl is performed the same principles apply but obviously using your tricep.
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
