  2. Isotonic contraction - Wikipedia

    en.wikipedia.org/wiki/Isotonic_contraction

    This is almost an isotonic contraction because there is some fluctuation towards the end of the contraction. For example, the heart's ventricles contract to expel blood into the pulmonary artery and aorta. As the blood flows out, the previous built-up load is decreased and hence less force is required to expel the rest of the blood.

  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. Tetanic contraction - Wikipedia

    en.wikipedia.org/wiki/Tetanic_contraction

    Tetanic contraction can exist in a variety of states, including isotonic and isometric forms—for example, lifting a heavy box off the floor is isotonic, but holding it at the elevated position is isometric. Isotonic contractions place muscles in a constant tension but the muscle length changes, while isometric contractions hold a constant ...

  5. Isometric exercise device - Wikipedia

    en.wikipedia.org/wiki/Isometric_exercise_device

    Isometric exercise devices perform exercises or strength test using static contraction of a muscle without any visible movement in the angle of the joint. This is reflected in the name; the term "isometric" combines the prefix "iso" (same) with "metric" (distance), meaning that in these exercises the length of the muscle does not change, [1] as compared to isotonic contractions ("tonos" means ...

  6. Science in science fiction - Wikipedia

    en.wikipedia.org/wiki/Science_in_science_fiction

    Science in science fiction is the study or of how science is portrayed in works of science fiction, including novels, stories, and films. It covers a large range of topics. Hard science fiction is based on engineering or the "hard" sciences (for example, physics, astronomy, or chemistry).

  7. Muscle energy technique - Wikipedia

    en.wikipedia.org/wiki/Muscle_energy_technique

    Post-Isometric relaxation: Treat by engaging the restrictive barrier in all planes. Reciprocal inhibition: Treat by contracting the antagonistic muscles, which causes the agonist muscle to relax through the reciprocal inhibition reflex arc. Joint mobilization using muscle force: Use muscle contraction to restore range of motion in a joint.

  9. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    An isometric contraction of a muscle generates tension without changing length. [ 1 ] [ 4 ] [ 5 ] [ 6 ] An example can be found when the muscles of the hand and forearm grip an object; the joints of the hand do not move, but muscles generate sufficient force to prevent the object from being dropped.
