The decline of physical activity in the conditions of modern life, on the one hand, and the insufficient development of mass forms of physical culture among the population, on the other hand, lead to deterioration of various functions and the emergence of adverse conditions of the human body.

To ensure normal functioning of the human body needs sufficient activity in skeletal muscle. The work of the muscular system contributes to the development of the brain and the establishment of inter-Central and intersensory relationships. Motor activity increases the production capacity and heat generation, improves the functioning of respiratory, cardiovascular and other body systems.

Scientific evidence suggests that most people in the observance of hygienic rules and maintaining a healthy lifestyle has the opportunity to live to 100 years or more.

Unfortunately, many people do not follow the simplest, Continue reading

Topic: “physiology”. The structure of the muscle fibers. Types and subtypes of muscle fibers. Muscle fibers — slow-twitch (MS) and fast-twitch (LH). The activity of aerobic, anaerobic enzymes. Similarities and

differences between male and female muscle fibres.

Structural and functional characteristics of motor units of the muscles. Muscle is an extremely heterogeneous tissue, composed mainly of muscle fibers, connective tissue, nervous and vascular elements, which together provide its main function — actively cuts. In the structure of muscle tissue there are two types of muscle fibers — slow-twitch (MS) and fast-twitch (LH). This division simplifies the tissue organization of the muscles, among which there are different kinds of muscles, due primarily to morphological and functional properties of their fibers. However, the selected Continue reading
