Features of body structure of female wrestlers and the construction of centile scales

Abstract

Objective: presentation of various women wrestlers' body constitution indicators in the form of basic factors and creation of estimated centile scales. Materials and methods: the material for this study was the results of the morphological surveys of the strongest wrestlers - freestyle women athletes, members of the Russian national teams, that participate in major international competitions (n = 162). Longitudinal, transverse and circumference body sizes as well as skinfold thickness was measured and body composition was analyzed by bioimpedance method in all women athletes. Based on received data the following calculated indicators were determined: proportions of the body, body composition, somatotype etc. Generally, the survey program included 142 different indicators characterizing the body constitution of women athletes. Results: the factor analysis of women wrestlers' body constitution identified 7 factors that explained 90,43% of generalized variance. Lean body mass (kg), skeletal muscle mass (%), forearm length (cm)/arm length (cm) index, pelvis-and-crest diameter (cm)/acromial diameter (cm) index, fat mass (%) (according to Mateiko), femur circumference (cm)/tibia length (cm) and foot height (cm) index, phase angle (deg.)were considered as valid indicators. Furthermore, valid indicators represented a maximal variability and dispersion of studied indicators in this sports specialization. It gives the basis to use them for development of estimated centile scales. Conclusions: analysis factor structure of elite women wrestlers' body constitution indicated that it can be described by 7 factors with high significant reliability (90,43%).
