"The striated muscles that appeared later on the phylogenetic scale have more white, fast fibers in their composition, more sensitive to metabolic aggression. Based on the composition, phylogeny and anatomical-functional characteristics, we selected the following muscles: semitendinosus, iliac, subscapular, extensor pollicis brevis and flexor pollicis longus. The data from the specialized literature show that the respective muscles are exposed to sports injuries. In principle, one can try to prevent injuries by changing the proportions in types of muscle fibers, possibly through physical exercises, but there is the potential danger of changing joint biomechanics. Keywords: striated muscles, phylogeny, fiber types, sports traumatology."
