  2. Tetanic contraction - Wikipedia

    en.wikipedia.org/wiki/Tetanic_contraction

    Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. [5] A fused tetanic contraction is the strongest single-unit twitch in contraction. [6] When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible ...

  3. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]

  4. Progressive muscle relaxation - Wikipedia

    en.wikipedia.org/wiki/Progressive_muscle_relaxation

    Individuals should perform progressive muscle relaxation in a comfortable place. [16] A person can begin the exercise while sitting or standing. [7] It is important to breathe throughout the entire exercise, [7] because some sources recommend breathing in while tensing the muscles and breathing out as the muscles are released. [7]

  5. Relaxation technique - Wikipedia

    en.wikipedia.org/wiki/Relaxation_technique

    It involves the effective and repetitive relaxation of 14 different muscle groups and has been used to treat anxiety, tension headaches, migraines, TMJ, neck pain, insomnia, bipolar disorder, anxiety, backaches, high blood pressure, etc. [17] PMR is a two-step practice that involves creating tension in specific muscle groups and then releasing ...

  6. Muscle tone - Wikipedia

    en.wikipedia.org/wiki/Muscle_tone

    In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. [1] [2] It helps to maintain posture and declines during REM sleep. [3]

  7. Reciprocal inhibition - Wikipedia

    en.wikipedia.org/wiki/Reciprocal_inhibition

    If opposing muscles were to contract at the same time, a muscle tear can occur. This may occur during physical activities such as running, during which opposing muscles engage and disengage sequentially to produce coordinated movement. Reciprocal inhibition facilitates ease of movement and is a safeguard against injury.

  8. Golgi tendon reflex - Wikipedia

    en.wikipedia.org/wiki/Golgi_tendon_reflex

    The Golgi tendon reflex operates as a protective feedback mechanism to control the tension of an active muscle by causing relaxation before the tendon tension becomes high enough to cause damage. [7] First, as a load is placed on the muscle, the afferent neuron from the Golgi tendon organ fires into the central nervous system.

  9. Isometric exercise - Wikipedia

    en.wikipedia.org/wiki/Isometric_exercise

    For example, in a bench press set-up the barbell can be held in a fixed position and neither pushed upwards nor allowed to descend. Alternatively, in a mid-thigh pull set-up, a person can attempt to pull a fixed, immovable bar upwards. Example of an unweighted overcoming isometric exercise
