  2. 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]

  3. 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. List of medical roots, suffixes and prefixes - Wikipedia

    en.wikipedia.org/wiki/List_of_medical_roots...

    This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.

  6. Anatomical terms of muscle - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_muscle

    The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [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.

  7. Motor unit - Wikipedia

    en.wikipedia.org/wiki/Motor_unit

    When necessary, the maximal number of motor units in a muscle can be recruited simultaneously, producing the maximum force of contraction for that muscle, but this cannot last for very long because of the energy requirements to sustain the contraction. To prevent complete muscle fatigue, motor units are generally not all simultaneously active ...

  8. Tensiomyography - Wikipedia

    en.wikipedia.org/wiki/Tensiomyography

    Tensiomyography is a non-invasive, evidence-based measurement method that precisely measures the speed of muscle contraction under isometric conditions.It is used in sports performance and rehabilitation, and in sports medicine and research, for instance.

  9. Sliding filament theory - Wikipedia

    en.wikipedia.org/wiki/Sliding_filament_theory

    The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement. [1] According to the sliding filament theory, the myosin ( thick filaments ) of muscle fibers slide past the actin ( thin filaments ) during muscle contraction, while the two groups of filaments ...
