  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. 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 ...

  5. 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 ...

  6. Eccentric training - Wikipedia

    en.wikipedia.org/wiki/Eccentric_training

    The definition of eccentric contraction is almost the exact definition of muscle strengthening. Perceived muscle damage: There is a stipulation regarding eccentric contractions in that they actually cause muscle damage and injury. Eccentric contraction may result in delayed onset muscle soreness however; the contraction itself does not cause ...

  7. Hill's muscle model - Wikipedia

    en.wikipedia.org/wiki/Hill's_muscle_model

    Therefore, the higher the load applied to the muscle, the lower the contraction velocity. 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]

  8. Physical geography - Wikipedia

    en.wikipedia.org/wiki/Physical_geography

    Soil geography deals with the distribution of soils across the terrain. This discipline, between geography and soil science, is fundamental to both physical geography and pedology. [8] [9] [10] Pedology is the study of soils in their natural environment. It deals with pedogenesis, soil morphology, soil classification.

  9. 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.
