The lengthening of a muscle is called 'relaxing'. As the SHORT muscles work antagonistically- when one contracts, one relaxes. Therefore as one muscle shortens the other lengthens. This is between the bicep and tricep and the hamstring and quadricep. When a muscle shortens it also thickens, this is why you can feel your muscle rise when you bring your arm towards you.

What reflex causes muscles relaxation and lengthening in response to muscle tension?
The reflex of the Golgi tendon.
What is the term that refers to the theory of rapidly lengthening a muscle followed by an immediate concentric contraction?
This is known as plyometric stretching, a form of dynamic stretching that combines rapid lengthening of a muscle with an immediate concentric contraction to improve power and explosiveness in movements.
Why does eccentric produce more force than concentric?
Eccentric muscle contractions involve the lengthening of the muscle under tension, which allows for greater force production compared to concentric contractions where the muscle shortens. This occurs because the muscle fibers can generate more force during the controlled lengthening process in eccentric contractions, leading to greater tension development.
When muscles lengthen?

What effect do calcium slow channels have on shortening or lengthening the contraction of the heart muscle?
Calcium slow channels, also known as L-type calcium channels, play a crucial role in regulating the duration of cardiac muscle contraction. Activation of these channels leads to an influx of calcium ions into the cardiac muscle cells, which triggers contraction. Inhibition of these channels can result in decreased contractility and lengthening of the contraction phase of the heart muscle.
How does muscle work by shortening or lengthening?
Muscles are comprised of contractile proteins; therefore, the ability to contract is present in their chemical composition.
What muscle actions would be classified as isotonic contractions?
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).

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.
What is the opposite of contraction in exercise against weight?
The opposite of contraction in exercise against weight is relaxation, which refers to the lengthening of a muscle after it has contracted. In terms of muscle actions, this is often described as an eccentric contraction, where the muscle lengthens under tension, such as when lowering a weight. This phase is crucial for muscle control and helps prevent injury.
An eccentric muscle action occurs when a muscle lengthens?
An eccentric muscle action occurs when a muscle generates force while lengthening, typically under tension. This type of contraction is crucial for controlling movement and absorbing shock, such as when lowering a weight or descending stairs. Eccentric actions can lead to muscle soreness but also play a significant role in muscle strengthening and overall functional performance.
