  2. Isotonic contraction - Wikipedia

    en.wikipedia.org/wiki/Isotonic_contraction

    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 relationship during a contraction, an isotonic contraction will keep force constant while velocity changes, but an isokinetic ...

  3. 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]

  4. Skeletal muscle - Wikipedia

    en.wikipedia.org/wiki/Skeletal_muscle

    Muscle also functions to produce body heat. Muscle contraction is responsible for producing 85% of the body's heat. [65] This heat produced is as a by-product of muscular activity, and is mostly wasted. As a homeostatic response to extreme cold, muscles are signaled to trigger contractions of shivering in order to generate heat. [66]

  5. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    An impulse from a nerve cell causes calcium release and brings about a single, short muscle contraction called a muscle twitch. If there is a problem at the neuromuscular junction, a very prolonged contraction may occur, such as the muscle contractions that result from tetanus. Also, a loss of function at the junction can produce paralysis. [5]

    [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso. This is the case when grabbing objects lighter than the body, as in the typical use of a lat pull down machine.

  7. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    Muscle is a soft tissue, one of the four basic types of animal tissue.Muscle tissue gives skeletal muscles the ability to contract.Muscle is formed during embryonic development, in a process known as myogenesis.

  8. Physiological cross-sectional area - Wikipedia

    en.wikipedia.org/wiki/Physiological_cross...

    A better estimate is provided by the total area of the cross-sections perpendicular to the muscle fibers (green lines in figure 1). This measure is known as the physiological cross-sectional area (PCSA), and is commonly calculated and defined by the following formula, developed in 1975 by Alexander and Vernon: [4] [5] [6]

  9. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    Therefore, the higher the load applied to the muscle, the lower the contraction velocity. Similarly, the higher the contraction velocity, the lower the tension in the muscle. This hyperbolic form has been found to fit the empirical constant only during isotonic contractions near resting length. [1]
