  2. Isometric exercise - Wikipedia

    en.wikipedia.org/wiki/Isometric_exercise

    An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction ...

  4. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]

  5. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    There are four main types of muscle contraction: isometric, isotonic, eccentric and concentric. [29] Isometric contractions are skeletal muscle contractions that do not cause movement of the muscle. and isotonic contractions are skeletal muscle contractions that do cause movement. Eccentric contraction is when a muscle moves under a load ...

  6. Isotonic contraction - Wikipedia

    en.wikipedia.org/wiki/Isotonic_contraction

    There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing. [citation needed]

  7. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    During isometric contractions the series elastic component is under tension and therefore is stretched a finite amount. Because the overall length of the muscle is kept constant, the stretching of the series element can only occur if there is an equal shortening of the contractile element itself.

    en.wikipedia.org/wiki/Muscle_fatigue

    In research studies, participants were found to show reduced voluntary force production in fatigued muscles (measured with concentric, eccentric, and isometric contractions), vertical jump heights, other field tests of lower body power, reduced throwing velocities, reduced kicking power and velocity, less accuracy in throwing and shooting ...
