    The isometric contraction occurs when the force your muscles create is equal to the force of your external load. When this happens, your muscles create force while neither lengthening nor shortening.

  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. Isovolumetric contraction - Wikipedia

    en.wikipedia.org/wiki/Isovolumetric_contraction

    The isovolumetric contraction phase lasts about 0.05 seconds, [1] but this short period of time is enough to build up a sufficiently high pressure that eventually overcomes that of the aorta and the pulmonary artery upon opening of the semilunar valves. This process, therefore, helps maintain the correct unidirectional flow of blood through the ...

  5. 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.

  6. This is the best exercise to lower blood pressure, study finds

    Keep breathing normally throughout an isometric contraction, he advises. It’s likely that repeating this pattern over several weeks results in sustained reductions in blood pressure, Edwards notes.

  7. Muscle energy technique - Wikipedia

    en.wikipedia.org/wiki/Muscle_energy_technique

    The patient's isometric contraction has the correct amount of force, the correct direction of effort (away from the restrictive barrier), and the correct duration (5-10 seconds). Complete relaxation occurs after the muscular effort. The patient is repositioned into the new restrictive barrier in as many planes as possible.

  8. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    There are four main types of muscle contraction: isometric, isotonic, eccentric and concentric. [29] Isometric contractions are skeletal muscle contractions that do not cause movement of the muscle. and isotonic contractions are skeletal muscle contractions that do cause movement. Eccentric contraction is when a muscle moves under a load ...

  9. Strength training - Wikipedia

    en.wikipedia.org/wiki/Strength_training

    Beginning strength-trainers are in the process of training the neurological aspects of strength, the ability of the brain to generate a rate of neuronal action potentials that will produce a muscular contraction that is close to the maximum of the muscle's potential.
