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
What happens in the human body when.
What happens in the body when conditions change in the external environment or physical activity? First of all is the adaptation (adaptation) of an organism to changed conditions, i.e., changing the rate of biological reactions. In the phenomenon of adaptation identify qualitative and quantitative components. The quantitative component is expressed in a continuous variation of the number of active structures. In normal conditions of functioning of the body “works” only a small part of the functional structures, ensuring its normal functioning. The load includes backup structure, the load reduction leads to a decrease in the number of
structures with active biosynthesis. This principle has been called alternately (asynchronous) work of the same structures. It is fair for all levels – from molecular to systemic. For longer loads, and the more constantly increasing, are incorporated in all new patterns; when there is insufficient inclusion of all structures, there is an increase in their number, i.e. the construction of new structures, Continue reading
