"From the bottom of my heart, dear Emma Peltz AndSechenov 12/1902"
In addition to physiology and scientific psychology based on it, Sechenov was also engaged in research on labor issues. In Sechenov's time, the length of the workers' working day depended on the arbitrariness of the factory owners and their henchmen. When, in the late 80s, information began to come from abroad about reducing the working day to eight hours, Ivan Mikhailovich settled into the laboratory and made a huge number of complex experiments. After numerous studies, Sechenov published An Essay on Human Labor Movements, which is the most important scientific guide in this field and for our time.
In this book, published in 1901, the following issues were considered in detail: the work of the musculoskeletal system (ODE) as a working machine (joint shapes, shoulders of muscle traction forces); mechanics of muscle contraction (factors determining muscle strength); biomechanical properties of the muscle (in particular, elastic properties of the muscle); functions the upper and lower extremities of a person as a working machine. In addition, some physical exercises were subjected to detailed biomechanical analysis: bending the arms in the vise, squatting and standing on one leg "pistol".
