During isotonic contraction

Author: yaux

August undefined, 2024

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. … WebDuring contraction the A band does not change length (2), though the sarcomere shortens, the distance between Z lines lessens, and the I and H bands narrow. Any theory of muscle contraction must account for these …
