Physical rehabilitation in sarcopenia: modern approaches. (A literature review)

The number of middle-aged and elderly population is increasing every year. At the same time, the course of most chronic diseases worsens with age, which can be explained by significant changes in body composition, including redistribution and increase of fat mass and decrease in muscle and skeletal mass. Thus, a decrease in muscle mass becomes intrinsic for the body from the age of 40 and develops on average by 0.5-1.0% per year. The prevalence of patients with sarcopenia is estimated to be between 11 and 50% in different age groups of population: middle, elderly and senile. In addition, the decline in physical activity associated with the urbanization and automation of labor exacerbates the disease at a younger age, which predicts an increase in the number of such patients in the future.
