eccentric contraction eccentric contraction, a type of muscle contraction that occurs as the muscle fibers lengthen, such as when a weight is lowered through a range of motion. The contractile force generated by the muscle is weaker than an opposing force, which causes the muscle to stretch.

Muscle contraction The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.Muscle contractions can be described based on two variables: length and tension.n contrast, a muscle contraction is isotonic if muscle length changes but the muscle tension remains the same. Furthermore, if the muscle length shortens, the contraction is concentric.

Muscle Contractions Isotonic Contractions. Isotonic contractions are those which cause the muscle to change length as it contracts causing movement. There are two types of isotonic contraction: -. Concentric. A concentric contraction is a type of muscle contraction in which the muscles shorten while generating force.

contraction noun. The definition of contraction is the lengthening or shortening of a muscle fiber or a word formed by combining the sounds of two longer words. 1  An example of a contraction is the action of the uterus during the birth process. 2  An example of a contraction is the word doesn't from does not.ontraction-Computer Definition. The shortening of a word or phrase by omitting letters or syllables. In the English language, a contraction generally, but not always, marks the omitted letters or syllables with an apostrophe or a period.

- Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.

How do muscles relax????? How does it occur??? Let's take a look at what occurs within a skeletal muscle, from excitation to contraction to relaxation 1  : An electrical signal (action potential) travels down a nerve cell, causing it to release a chemical message (neurotransmitter) into a small gap between the nerve cell and muscle cell.

Muscle contraction Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.f the muscle length changes while muscle tension remains the same, then the muscle contraction is isotonic. In an isotonic contraction, the muscle length can either shorten to produce a concentric contraction or lengthen to produce an eccentric contraction.

Muscle contraction Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.n skeletal muscles, muscle tension is at its greatest when the muscle is stretched to an intermediate length as described by the length-tension relationship. Smooth and cardiac muscle contractions are myogenic and can be modulated by the autonomic nervous system.

eccentric contraction eccentric contraction. 1  controlled relaxation of a contracted muscle, movement occurring as a result of the lengthening of the muscle(s). 2  A lengthening action in which a muscle's attachments are drawn away from one another by an external resistance, even though the muscle is activated. Often called negative work.

- Labor contractions are the periodic tightening and relaxing of the uterine muscle, the largest muscle in a woman's body.Something triggers the pituitary gland to release a hormone called oxytocin that stimulates the uterine tightening.ontractions are often described as a cramping or tightening sensation that starts in the back and moves around to the front in a wave-like manner. Others say the contraction feels like pressure in the back.
