In strength sports, physical activity in an isometric (static) mode is widely used, but the underlying mechanisms that influence the cardiovascular system's parameters have not been fully studied. The relationship between dosed static load and anthropometric parameters attracts even less attention from specialists in sports, physical education and sports medicine. Therefore, our study aimed to investigate reactive changes in the activity of the heart and blood vessels after static exercise in individuals with different body mass index (BMI). We studied 21-year-old men with normal and elevated BMI, changes in the parameters of the circulatory system were recorded using tetrapolar thoracic rheoplethysmography, and the static load was modelled by holding a force of 50% of the maximum force on the DS200 state dynamometer for 15 seconds. Central haemodynamic parameters were recorded before the load was applied and within 3 minutes after it. Statistical data processing was performed using the computer program IBM SPSS Statistics, version 26, using nonparametric methods of evaluating the results obtained. It has been established that isometric physical activity in young men with different BMI causes the same nature of changes in the parameters of central haemodynamics. Differences in body mass index and body weight affect only the degree of manifestation of reactive changes in the circulatory system. During rapid recovery after static exercise, the Lingard phenomenon was more pronounced in individuals with a high body mass index.
