Abstract: | At examination of 305 boys and girls Russian, Kazakh in Alma-Ata strength of the m. triceps surae (strength of the foot flexion) has been estimated, anatomical diameter of this muscle and strength per 1 sm2 of the anatomical diameter (specific strength) has been calculated. Somatotyping after V. N. Shevkunenko has been performed. At dolichomorphy the specific strength is higher than at brachymorphy. In 24 corpses of 18-38-year-old men typical peculiarities of construction and structure of the m. triceps surae is studied. Correlation of the m. triceps surae parts and degree of its pinnateness do not reveal any definite differences in connection with the complexion. As demonstrate the data of light microscopy and mathematical treatment of the results by means of mixtures method statistically reliable predominance of the connective tissue component in the m. triceps surae and more often occurrence of thick muscle fibers in the m. soleus at dolichomorphy is stated. According to the electron microscopy data, better development of the connective tissue carcass of the m. triceps surae is proved in persons of dolichomorphic complexion. |
