Biological prerequisites for developing a concept of physical and sports rehabilitation for women aged 36–45 at risk of developing cardiovascular diseases

Background and Study Aim. In women of the second period of mature age, the risk of developing cardiovascular diseases increases, which is associated with significant biological changes. The purpose of the study is to use factor analysis to justify the prerequisites for developing a concept of physical and sports rehabilitation for women in the second period of middle age with modified risk factors for cardiovascular disease. Material and methods. The study involved 79 women who were divided into two groups: a group of 36-40 years old – 36 people, a group of 41-45 years old – 43 people. Factor analysis was performed using the principal component method with Varimax rotation. The starting point was the study of the statistical relationship between physical, physiological, and biomechanical parameters and the risk of developing cardiovascular diseases. Results. Factor analysis was used to identify groups of interrelated indicators that have the greatest impact on the overall health of women. The factor analysis of parameters in women aged 36–40 years allowed us to identify five factors that influence the risk of cardiovascular disease: age-related and adaptive changes; cardiovascular response to exercise; metabolic disorders; functional state of the cardiovascular system; and psychoemotional state. In women aged 41–45, the structure of factors reflects a deterioration in vascular reactivity, a strengthening of the link between psychoemotional state and somatic indicators, and the identification of blood pressure as a separate risk factor for cardiovascular disease. Conclusions. In women aged 36–40, five factors were identified that reflect the relationship between age, adaptive abilities, excess body weight, heart rate, and anxiety. In women aged 41–45, there are also five factors, but with different content: cardiovascular adaptation, cardiovascular response to exercise, metabolic risk, psychoemotional state, and hypertensive factor.
