[Answer] What is concentric muscle contraction?

Answer: A contraction of the muscle in which the muscle shortens.
What is concentric muscle contraction?

Muscle contractions can be described based on two variables: force and length. Force itself can be differentiated as either tension or load. Muscle tension is the force exerted by the muscle on an object whereas a load is the force exerted by an object on the muscle. When muscle tension changes without any corresponding changes in muscle length the muscle contraction is described as isometric. If the muscle length changes while muscle tension remains the same then the muscle contraction is isotonic…

In an isotonic contraction tension remains the same whilst the muscle’s length changes. Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical as the muscle’s force changes via the length-tension relationshipduring a contraction an isotonic contraction will keep force constant while velocity changes but an isokinetic contraction will keep velocity constant while force changes. A near isotonic contraction is kno…

A muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same.[1][2][3][4] In contrast a muscle contraction is isotonic if the muscle length changes but the muscle tension remains the same.[1][2][4][3] Furthermore if the muscle length shortens the contraction is concentric.[1][5] But if it lengthens the contraction is eccentric.

It’s the exact definition of a muscle contraction – the joint opens and the muscle lengthens despite the action of the contractile proteins. Muscle contraction is the statement used to descri…
