Today among geriatric syndromes, world scientists pay much attention to the study of sarcopenia. It was found that the evaluation of skeletal muscle strength has a significant correlation with the risk of falls, disability, deterioration in the quality of life, duration of hospitalization. It is proved that measurements of skeletal muscle strength, but not the determination of skeletal muscles mass, are strong and independent predictors of mortality in the elderly. Further researches are needed to study the characteristics of weight loss, strength and function of skeletal muscle with age in individuals of different sex and age. The objective of this study was to explore the features of strength and functionality of skeletal muscle tissue in women of all ages. The study involved 248 women, who were divided into groups by decades depending on age: 20–29, 30–39, 40–49, 50–59, 60–69, 70–79, 80–89 years. Skeletal muscle strength was evaluated using spring carpal dynamometer. Functions of skeletal muscles and the risk of falls were assessed using special tests. Fat-free mass of the whole body, upper and lower extremities was evaluated by means of dual-energy X-ray absorptiometry (Prodigy, GEHC Lunar, Madison, WI, USA). The study found that maximal values of strength and functional capacity of skeletal muscles were observed in women in the age group of 20–29 years. The significant loss of skeletal muscle strength is being detected in individuals from the age group of 60–69 years and older. When determining the functional capacity of skeletal muscles and risk of falls, significantly worse performance was established in women older than 50 years compared to those in women in the age group of 20–29 years.
