Abstract
Muscular hypertrophy changes the rates of growth of the different parts of the musculature. This affects the weight ratio between these parts and the partition of the different chemical components.
The ratios between protein — lipid and water content are different in muscles of hypertrophied animals as compared to normal animals. It is mainly the proportion of the various proteins which is affected. Typically there is a drop of the collagen content in the various muscles of the hypertrophied animals in comparison with homologous muscles from normal animals.
Some other components, such as myoglobin, change in relation to the distribution of the metabolic types of fibre.
Résumé
L’hypertrophic musculaire héréditaire change la vitesse de croissance des différents éléments de la musculature, ce qui modifie les rapports pondéraux entre les muscles. La répartition des différents composants chimiques est également affectée. Les rapports protéine-lipide-eau sont différents dans les muscles des animaux hypertrophies comparés aux muscles des animaux normaux. C’est surtout la proportion des différentes protéines qui est modifiée. Il y a une baisse caractéristique du taux de collagène dans les differents muscles des animaux hypertrophiés en comparaison avec les muscles homologues des animaux normaux.
D’ autres composants comme la myoglobine sont modifiés en relation avec la distribution diffèrente des divers types métaboliqvies de fibres musculaires.
