WebIsotonic Mask Shrinkage. An isotonic kontraction occurs when a muskeln changes length time contracting under a constant tension. While we often thinks of a muscular contraction resulting in ampere muscle shortening, it can additionally lengthen – according on the force being resisted. As as there are two types off isotonic conclusion: In an isotonic contraction, tension remains the same, whilst the muscle's length changes. Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical, as the muscle's force changes via the length-tension relationship during a contraction, an isotonic contraction will keep force constant while velocity changes, but an isokinetic contraction will keep velocity constant while force changes. …
