Titin is a giant protein, greater than 1 µm [micrometre] in length, that functions as a molecular spring which is responsible for the passive elasticity of muscle. It is composed of 244 individually folded protein domains connected by unstructured peptide sequences. These domains unfold when the protein is stretched and refold when the tension is removed. 2, record 1, English, - titin

Par ordre d’abondance, la troisième protéine de la fibre de muscle squelettique des vertébrés est la titine, qui est la plus volumineuse de toutes les protéines jusqu'ici chez des organismes. L'ensemble du gène de la titine(qui peut être à l'origine d’isoformes de longueurs différentes) code un polypeptide d’une masse de plus de 3, 5 millions de daltons et composé de plus de 38 000 acides aminés [...] La titine est une protéine très élastique qui s’étire comme un ressort moléculaire quand certains domaines de la molécule se déplient. On pense qu'elle évite la scission du sarcomère au cours de l'étirement du muscle. Elle préserve aussi la position correcte des filaments de myosine au centre du sarcomère pendant la contraction musculaire. 3, record 1, French, - titine

Muscle contractions which result in movement are known as isotonic contractions. There are two types of isotonic muscle contraction: concentric and eccentric ... Eccentric contractions are the opposite of concentric contractions. The muscle contracts but increases in length. This type of contraction occurs usually in the direction of gravity, to control a movement. For example, using the same biceps curl exercise - as the arm is slowly straightened from the bent position, the Biceps Brachii muscle contracts eccentrically to control the downward movement and increase the angle at the joint. 2, record 2, English, - eccentric%20contraction

Les muscles peuvent encore exercer de la force lors d’une contraction avec allongement du muscle. Ce mouvement est appelé contraction excentrique [...] Pour l'illustrer, citons l'action du muscle biceps brachial, lorsque le coude s’étend pour poser un poids très lourd. Dans ce cas, les filaments d’actine s’éloignent du centre du sarcomère en l'étirant. 2, record 2, French, - contraction%20musculaire%20excentrique

Le sarcomère est l'unité fonctionnelle fondamentale de la myofibrille. Chaque myofibrille est composée de nombreux sarcomères accolés entre eux par les stries Z.
