What else can I help you with?
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 a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
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.
How does it feel to perform a bicep curl exercise and experience the contraction in your forearm muscles?
Performing a bicep curl exercise can feel like a tightening or squeezing sensation in your bicep muscle. When you experience the contraction in your forearm muscles, it may feel like a strong, tense sensation as those muscles work to support the movement.
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.
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.
Is a bicep curl an isotonic or isometric exercise?
A bicep curl is an isotonic exercise.
What includes both concentric and eccentric contractions?
Isotonic muscle contractions involve both concentric (muscle shortening) and eccentric (muscle lengthening) phases. In isotonic contractions, the muscle changes in length while maintaining a constant tension, such as when lifting a weight or performing a bicep curl.
