The article discusses the dynamics of the functional state of the cardiovascular system (CVS) in individuals after laparoscopic cholecystectomy (LCС) under the influence of a rehabilitation program in SANATORIUM-RESORT CONDITIONS. The study involved 79 individuals after LCC aged 45 to 59 years. The individuals were divided into 2 groups: group A (n=39) and group B (n=40). Individuals in group A received rehabilitation services according to the clinical protocol (diet, hydrotherapy, mineral or coniferous baths, and physical therapy, etc.) In group B, individual rehabilitation programs were formed depending on the existing dysfunctions and the tolerance of the CVS to physical activity. In group B, the rehabilitation intervention to increase the function of endurance and physical performance was applied Nordic walking (NW). The initial examination in both groups revealed an increase in resting heart rate (RHR), diastolic (DBP) and systolic (SBP) blood pressure, a decrease in the performance of a 6- minute walk test and the presence of a feeling of shortness of breath during the test. The implementation of a physical rehabilitation (physical therapy) program in group B, which used Nordic walking to increase physical activity, tolerance to physical activity, and improve cardiovascular function, was effective. The use of NW in sanatorium-resort conditions of rehabilitation (lasting at least 18 days) has a positive effect and leads to a statistically significant decrease in RHR, SBP, DBP, an increase in walking distance in 6 minutes and a decrease in the feeling of shortness of breath when walking, compared to the control group. It was established that diet therapy, hydrotherapy, mineral or coniferous baths, and other water procedures, classical abdominal and back massage, group daily therapeutic gymnastics in group A did not have a positive effect on increasing the level of physical activity tolerance, CVS functioning in patients after LCC.
