SOMATOMETRIC FEATURES OF THE PHYSICAL DEVELOPMENT OF YAKUT MEN ACCORDING TO THE REES-EISENCK INDEX

Background. Physical development is one of the generally recognized indicators of health. Scientific research aimed at studying the constitution and composition of the body of the male population using various techniques is an urgent task of modern medicine and human biology. The aim of the study was to determine the somatotypological features of the physical development of yakut men according to the Rees-Eisenck index. Materials and methods. An anthropometric and bioimpedance examination of 55 men of yakut nationality, the first and second periods of adulthood was conducted. The anthropometric part of the study included the measurement of body length and weight, waist and hip circumference, pelvic diameter and transverse chest diameter. Somatometric indices were calculated: BMI, Rohrer index, the ratio of waist circumference to buttocks. The definition of body types was carried out according to the Rees-Eisenck index. Bioimpedance measurement was carried out using the analyzer of body composition and balance of water sectors of the body ABC – 01 “Medass”. The amounts of relative and absolute fat mass, musculoskeletal mass, lean mass, active cell mass were determined. Statistical processing of the obtained material was carried out by parametric and nonparametric methods using the SPSS 17,0 application software package. Results. The predominant body type was the picnic type (76,6%). Comparison of the indicators revealed significantly large values of body weight, BMI, waist and buttock circumference, transverse chest diameter, pelvic diameter and relative fat mass in persons with a picnic body type. Parameters of musculoskeletal mass, lean mass and total hydration of the body in picnics were significantly lower than those of normostenics. Overweight and obesity were significantly more often registered in persons with picnic somatotype. Conclusion. Thus, the obtained anthropometric and bioimpedance data allow us to classify men with a picnical type of physique into a risk group for the development of pathology of different body systems.
