Text G. Professor Lesgaft’s scientific Research

Professor P.P. lesgaft was born in 1837. He was a prominent Russian anatomist and 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 Peterburg.

About 130 scientific works were written by Professor 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 hisworks which was written in 1892 Professor Lesgaft divided the muscles into two basic groups – static and dynamic [daI`næmIk]. In his work they were called strong and skilled (chaqqon). He 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 Professor K. Koveshnikova, whoreceived 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 from of nerve endings.
