Text G. Professor Lesgaft̓s Scientific Research

Prof. P.F. Lesgaft was born in 1837. He was a prominent Russian anatomist and a talented teacher. He was the first scientist in our country to work out the science of physical culture. He studied at the Medical Academy. After he graduated from the Academy he worked for the Degree of Doctor of Medicine. This degree was given to him in 1865 and in 1868 he received the Degree of Doctor of Surgery. Then he worked as the Professor of Anatomy at Kazan University. In 1886 he began to deliver lectures in Anatomy in Petersburg.

About 130 scientific works were written by Prof. Lesgaft. Many of them were translated into foreign languages. One of his main works was the book called The Basis of Theoretical Anatomy.

In one of his works which was written in 1892 Prof. Lesgaft divided the muscles into two basic groups - static and dynamic [dai'nfmik]. In his work they were called strong, and skilled ( ловкие ). Не determined that the static muscles were connected with large surfaces of the bones far from the point of their origin; they were formed by short bands of muscular fibers; the dynamic muscles were composed of the bands of long muscular fibers.

His studies on static and dynamic muscles were continued by Prof. A.K. Koveshnikova, who received many interesting findings. In 1954 it was determined by her experiments on animals that static and dynamic muscles were different in the number of nerve fibers and the form of nerve endings.
