  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 ...

  3. 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 ...

  4. Dynamic Tension - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Tension

    "Dynamic Tension" is the name Charles Atlas gave to the system of physical exercises that he first popularized in the 1920s. Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were ...

    For example, when learning a row, focus first on driving your elbows behind you rather than every component of the movement (like engaging the biceps muscle, activating the rhomboid, etc ...

  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. Isoinertial - Wikipedia

    en.wikipedia.org/wiki/Isoinertial

    The great utility of the isoinertial method and at the same time what makes it different from the normal isotonic muscle movement lies in the fact that the action isotonic developed in conventional exercises (strength machines and free weights), the resistance is constant throughout the whole of movement in both the concentric phase in which ...

  8. Muscle Atrophy Research and Exercise System - Wikipedia

    en.wikipedia.org/wiki/Muscle_Atrophy_Research...

    There is a BMU for each mode of muscle contraction, including: isometric (muscle contraction at a fixed length, i.e. no movement), isotonic concentric (muscle shortens as it contracts at a constant torque), isokinetic concentric (muscle shortens as it contracts but at a constant velocity), isotonic and isokinetic eccentric (muscle extended).
