The muscle lengthens during a process called eccentric contraction. In this type of contraction, the muscle generates force while being elongated, such as when lowering a weight or during the downward phase of a squat. Eccentric contractions are important for activities that require controlled movement and help to build muscle strength and stability.

What is the muscle action that occurs when the muscle lengthens while exerting a force to overcome a resistance?
The muscle doesn't lengthen to exert a force. There is actually a muscle on the other side of the bone, that is contracting, exerting the force. Example, most everyone knows of the Bicep (the big muscle on the your arm that guys like to flex for the ladies). Well, the tricep is on the other side (on the back of your arm, connecting to the elbow) and that muscle contracts in order to extend your arm outwards.
Which allows the body to move by stretching and contracting?
Muscles allow the body to move by stretching and contracting. When a muscle stretches, it lengthens, and when it contracts, it shortens. This movement is controlled by signals from the brain through the nervous system.
The type of muscle contraction that is most likely to cause soreness is an isometric contraction?
When you lift the weight with jerk, your muscles may get sore. Few muscle fibers may get dead and get replaced with fibrous tissue, later on. You are supposed to lift the weight up to sixty percent of the maximum capacity, carefully tested.
What is the antagonist of the masseter?
The antagonist of the masseter muscle is the digastric muscle. It helps to open the jaw by working against the masseter muscle during swallowing and speaking.
What triangular shaped muscle area within the bladder contracts during urination?
The detrusor muscle is the main muscle within the bladder that contracts during urination to help expel urine. It is a smooth muscle that forms a triangular shape at the base of the bladder.
What muscle lengthens during movement?
During movement, the muscle that lengthens is typically the antagonist muscle, which opposes the action of the primary mover (agonist). For example, when you extend your arm, the biceps (agonist) contracts while the triceps (antagonist) lengthens. This lengthening allows for controlled movement and stabilization of the joint involved. This process is known as eccentric contraction.
Can skeletal muscle contract without shortening?
Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).
A muscle contraction means the muscle lengthens as it relaxes true or false?
false
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
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.
A contraction in which a muscle exerts force lengthens and is overcome by a resistance?
Eccentric contraction (isotonic)
Would extending be an isotonic contraction?
No, extending a muscle is not considered an isotonic contraction. Isotonic contractions occur when a muscle changes length while maintaining a constant tension, such as during lifting or lowering a weight. In contrast, extending typically refers to the lengthening of a muscle under tension, which can occur during eccentric contractions, where the muscle lengthens while still generating force.
What is the antagonist muscle when performing leg curl?
The triceps lengthens when the biceps contracts, making the triceps the antagonist.
What are the differences between isometric, concentric, and eccentric muscle contractions?
Isometric muscle contractions happen when the muscle stays the same length, concentric contractions occur when the muscle shortens, and eccentric contractions occur when the muscle lengthens.
What does contraction mean in medical terms?
contract or "contraction" is when a muscle fiber lengthens or shortens
What is scientific word use when a muscle gets longer and get shorter?
The scientific terms for these processes are "eccentric contraction" and "concentric contraction." During eccentric contraction, a muscle lengthens while generating force, often when resisting an external load. Conversely, during concentric contraction, a muscle shortens while actively generating force, typically when lifting or moving a load. Together, these actions are essential for muscle function and movement.
