The morphological assessment of highly qualified ski racers

An athlete of each kind of sport has a certain type of external body composition peculiar only to him, his somatic type. The physique and the state of the musculoskeletal system are important criteria for sports orientation and sports selection. The assessment of body types and its component composition is also one of the defining criteria for the selection and orientation of highly qualified skiers aimed at achieving success in competitive activities. The purpose of the study: using the method of three-level variation, to establish the features of the model parameters of the body of highly skilled cross-country skiers and assess the degree of their biological maturity. 19 masters of sports of Russia in highly qualified skiing, male and female, took part in the survey. In the course of the study, the anthropometric method was used, the body types of athletes were determined using the method of Dorokhov, which made it possible to reveal their morphological status and body composition. Analysis of the total body dimensions revealed that the average body length of male skiers was 177±2,3 cm, body weight - 72,7±2,15 kg, for female skiers -162,4±2,4 cm and 60,4±3,2 kg, respectively, which is consistent with the results reported in the literature. Variants of the biological development of the subjects are highlighted. An analysis of the studies carried out made it possible to state that cross-country skiers, on average, reach biological maturity by the age of 22. Bioimpedancemetry showed the symmetry of various parts of the body and its influence on the performance of basic motor actions. A high positive relationship between total body sizes and an inverse relationship between its fat and muscle components was established. Characterization of body types revealed the predominant distribution of body components in the zone of micro-mesosomal variation. The assessment of body types of athletes confirms the opinion of experts that weight loss increases the speed abilities of an athlete and reflects the direction of the training process. The developed evaluation coefficients, somatic types and variants of biological development will make it possible to select young athletes for cross-country skiing.
