Abstract
The elemental status plays a key role in maintaining the vital balance in the body and deviations in which lead to the development of a particular pathology. Sarcopenia—an age-related condition characterized by a decrease in muscle mass, strength, and functionality, is a serious public health problem, especially against the background of global population aging. One of the significant but little-studied factors influencing the development of sarcopenia is the elemental status of the body of elderly and senile people. Macro- and microelements such as zinc, magnesium, selenium, iron, and calcium play an important role in regulating muscle metabolism, antioxidant protection, and anti-inflammatory activity. Deficiency of these elements can significantly accelerate the development of sarcopenia, worsen the general condition of elderly patients and increase the risk of disability. Studying the relationship between the level of vital trace elements and the manifestations of sarcopenia allows us to better understand the pathogenesis of this condition, develop methods for early diagnosis and reasonably apply nutritional correction. Conducting research in this area is an important step towards developing personalized prevention and treatment strategies that help improve quality of life and reduce the burden of chronic age-related diseases.
