  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. 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 ...

  5. 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).

  6. 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]

  7. Plank (exercise) - Wikipedia

    en.wikipedia.org/wiki/Plank_(exercise)

    Muscles involved in the side plank include: Primary: transversus abdominis muscle, gluteus medius and gluteus minimus muscles (abductors), the adductor muscles of the hip, and the external and internal obliques. Secondary: gluteus maximus (glutes), quadriceps (quads), and hamstrings.

  8. Isotonic - Wikipedia

    en.wikipedia.org/wiki/Isotonic

    The term isotonic may refer to: Isotonic (exercise physiology), a type of muscle contraction; Isotonic regression, a type of numerical analysis; Isotonic, one of three types of tonicity that characterize a solution's concentration; see Tonicity#Isotonicity; A sports drink that contains similar concentrations of salt and sugar to the human body
