Introduction Studies of resilience and aging have recently been actively conducted using data obtained from various sources and fields of knowledge. Despite this, there is no single deep understanding of the physical aspect of age-related viability, as well as its variability in different age periods. The results of various studies are not consistent with each other and require clarification. Material and methods. Patients undergoing respiratory rehabilitation of two age groups were examined: 32 middle-aged patients (45-59 years old) and 32 elderly patients (60-74 years old) according to the WHO classification. In the study, a physical examination was performed using a traditional routine technique using spiroarteriocardiorhythmography (SACR) at rest and when performing functional tests. Results. Methodology for assessing the regulatory circulatory system, using an expert system for SACRa in the physiological aspect of the resilience of patients of various age groups with pulmonological pathology. Conclusion. Based on the presented results, the authors recommend the use of clusters for assessing the functional tension of systems, including indicators of autonomic regulation of blood circulation, to quantify the physical aspect of age-related resilience.
