  2. Isotonic contraction - Wikipedia

    en.wikipedia.org/wiki/Isotonic_contraction

    A near isotonic contraction is known as Auxotonic 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 ...

  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

    When muscle tension changes without any corresponding changes in muscle length, the muscle contraction is described as isometric. [1] [4] [5] [6] If the muscle length changes while muscle tension remains the same, then the muscle contraction is isotonic.

  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. Isometric walking - Wikipedia

    en.wikipedia.org/wiki/Isometric_walking

    Isometric walking is a type of exercise that focuses on the muscles in the upper body and core. The exercises involve doing isometric contractions, which means holding a muscle in a fixed position for 15 to 60 seconds while applying resistance. By doing this, individuals can use up to 60-70% of their maximum force capacity.

  7. 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 ...

  8. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    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] The muscle tension decreases as the shortening velocity increases. This feature has been attributed to two main causes.

  9. 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).
