FUNCTIONAL CHARACTERISTICS OF THE CIRCULATORY SYSTEM IN MARTIAL ARTISTS FROM YAKUTIA: RELATION TO HEMODYNAMICS

Abstract

Aim. To identify the functional characteristics of the circulatory system among elite martial artists in Yakutia, with a focus on the influence of different hemodynamic profiles. Materials and methods. The methodology included somatometric and functional assessments of 49 participants, including measurements of body dimensions (body length and body mass), muscle mass, and calculation of various indices such as the functional change index, double product, endurance coefficient, vegetative index, systolic blood volume, minute blood volume, and total peripheral vascular resistance. Hemodynamic patterns were clas­sified, and statistical analyses were conducted using SPSS 22.0. Results. Our findings indicate that the majority of the athletes (46.9 %) exhibited eukinetic hemodynamics. Athletes with hypokinetic hemodynamics demonstrated larger body weights; whereas those with hyperkinetic hemodynamics displayed high relative muscle tissue. Notably, persons with hypokinetic hemodynamics showed lower values in parameters such as double product, systolic and minute blood volumes, and pulse pressure, alongside elevated total peripheral vascular resistance and diastolic blood pressure both pre- and post-exercise, elevated post-exercise pulse values. Hyperkinetic athletes exhibited lower total peripheral vascular resistance and diastolic blood pressure, coupled with higher values in double product, systolic and minute blood volumes, and pulse pressure prior to exercise. These observations suggest that the hemodynamic profiles observed in Yakutian hyperkinetic athletes may be attributed to the enhanced development of the muscular component, influenced by the region’s extreme environmental conditions. Conclusion. Consequently, the identification of an athlete's hemodynamic type becomes crucial in tailoring training regimens and rehabilitation strategies to optimize performance and health outcomes under the specific challenges posed by Yakutia's climate and terrain.
