  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. When Gravity Fails - Wikipedia

    The book's other main themes are the effects of drug use and alternate personality technologies, as well as the personal interactions and increasing isolation of a flawed protagonist. It is the first book in Effinger's "Marîd Audran" series, named after the protagonist, and was followed by A Fire in the Sun in 1989 and The Exile Kiss in 1991.

  4. 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 ...

  5. 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.

  6. 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 ...

  7. Contraction (short story) - Wikipedia

    en.wikipedia.org/wiki/Contraction_(short_story)

    "Contraction" (Chinese: 坍缩, Pinyin: tānsuō) is a science-fiction short story by Chinese writer Liu Cixin. [1] It was published in Science Fiction World in Chongqing in 1999 and in the anthology To Hold Up the Sky in October of 2020.

  8. Isolytic muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Isolytic_muscle_contraction

    Isolytic contraction is when a muscle contracts while external forces cause it to lengthen. [1] For example, during a controlled lowering of the weight in a biceps curl , the biceps are undergoing isolytic contraction.

  9. Tau Zero - Wikipedia

    en.wikipedia.org/wiki/Tau_Zero

    The novel was based upon the short story "To Outlive Eternity" appearing in Galaxy Science Fiction in 1967. It was first published in book form in 1970. It was first published in book form in 1970. The book is a quintessential example of " hard sci-fi ", as its plot is dominated by futuristic technology grounded in real physics principles.
