Scientists have discovered the role of leptin protein in heart disease in people whose lifestyle is characterized by reduced mobility, and has shown them how the body's internal mechanisms function in physical activity.

According to the journal Nature Medicine, which published the results of this scientific study, regular exercise protects the heart and blood vessels and reduces the risk of high cholesterol and blood pressure. But another risk associated with chronic inflammatory processes is the development of atherosclerotic plaques, which grow and block the arteries.

Massachusetts hospital experts in Boston, United States, have shown from laboratory results that physical activity affects the process of blood formation in the body.

Vertebrate blood formation takes place in the bone marrow, where stem cells are then generated that grow into various types of blood cells, including inflammatory white blood cells.
