The direct energy source for muscle contraction is the reaction of enzymatic hydrolysis (hydrolysis – the cleavage of chemical bonds in a molecule of a substance with water) molecules of adenosine triphosphate (ATP).
Cleavage reaction adenosine triphosphate is accompanied by the release of a significant amount of energy used during muscle activity. ATP is the universal energy source for all biological processes in a living organism
(in all cells and cellular structures of living organisms). Adenosine triphosphate (ATP) refers to high-energy compounds that differ by the presence of chemical bonds, which accumulated a large amount of free energy.
The enzymatic reaction of ATP hydrolysis is irreversible.
If the contraction Continue reading

Ways to workout at work
Most people work full time and have a few hours of exertion or increased mental activity and prolonged static position. To avoid inactivity and fatigue, it is necessary to provide sufficient physical and emotional relief in between work and other times.
Physical culture of the organism is not only the key to health, but also a way to improve performance. There is a misconception about exercise. It is believed that work affects health and causes weakness. It is not so. Of course, overload the body will not help maintain the tone and will cause
fatigue and weakness. However measured, the adjustable load will help maintain alertness and performance throughout the day.
The correct mode of work is the change of activities, the alternation of mental stress and physical labor. The normal workday Continue reading
Milk, dairy products
Milk – definition, liquid food, secreted by the mammary glands of females of almost all mammals for rearing offspring.
The milk of domestic cattle, sheep, goats, horses, camels and reindeer has been used as food since prehistoric times, as in its natural form, and for preparation of butter, cheese and various kinds of milk with enzymes, such as yogurt.
Milk is a suspension of fat and protein in water, sweetened with lactose. The proportions of these components vary in different mammals; cow’s milk contains 87,1% water, 3.4% protein and 5.9% body fat. In the modern dairy industry, the milk is pasteurized at a temperature of 72 °C for 16 h. for the destruction of all pathogenic germs. However, the milk goes sour for one or two days due to the effects of lactic acid bacteria.
Milk is inextricably linked with the life of man from birth: from breast Continue reading
Proper breathing during exercise
Take a breath – this is natural and important for the entire body process. Often we breathe without thinking. But it is necessary to cut off oxygen – life slows down.
The majority of people only breathe during sleep, in a state of complete relaxation when the breath is controlled unconsciously. During wakefulness the breath goes astray, and sometimes delayed, which could cause serious disruptions in such important organs as the heart and brain.
Meanwhile, learning to control your breathing, it is possible not only to preserve health, but also to live much longer. Proper breathing during fitness activities will greatly enhance the effectiveness of your workout, because then the muscles will better recover, you will be less tired and will be able to achieve the required result.
Proper breathing during exercise depends Continue reading
