Background and Study Aim. To develop and justify the criteria for morphogenetic markers of speed-power abilities of athletes and the main directions of individualization of the process of their preparation, taking into account the characteristics of the female body. Material and Methods. Using the “2D: 4D” determination methodology, finger proportions were analysed for 126 qualified athletes specializing in speed-strength types (sprinting and hurdling, jumping, shot-putting) of different ages (from 17 to 25 years old). For 13 weeks, eight qualified short-distance student runners were regularly tested using computer strain gauge equipment: 5 masculine and 3 feminine types. The tensodynamograms of the manifestation of the strength of muscle groups carrying the main load in the structure of the sprint run were recorded and processed. Results. It was found that 78% of the examined athletes observed finger proportions close to the "male" proportions. This may indicate their certain masculinization. The technique used for this can be an informative and simple marker to predict a genetic predisposition to the ability of effective performance of speed-power work. It was determined that the same amount of power load causes masculine athletes, runners for short distances, a more significant deployment of long-term adaptation restructuring of masculine athletes, runners for short distances, compared with athletes of a different gender identity. Conclusions. Criteria for the prognostic assessment of speed-power abilities of athletes based on simple biological markers for testing and identification, like finger proportions (2D: 4D), have been developed. For athletes of high qualification who have a gender identity similar to men and a masculine somatotype, it is possible to use adapted male techniques for training.
The aim: This paper's aim is to assess the level of development and size of particular body parts and dimorphic differences with regard to body height. Methods: The research was carried out over the period of 1995-2010 on a 1,969-strong cohort of first-year students of physical education, aged 19-21. The following somatic features were measured: body height and weight, breadth of distal femoral epiphysis, breadth of distal brachial epiphysis, four skinfolds, arm circumference, and calf circumference. Using the results, the shares of endomorphy, mesomorphy, and ectomorphy were calculated as well as the mean values of particular features and their supplemental values and regression equations. Results: With regard to height, the women students exhibit higher share of endomorphy than do the men students who, in turn, are characterised by a higher share of mesomorphy, the differences being statistically significant. The women also exhibit a higher share of ectomorphy, with differences statistically significant. The regression equation shows that the share of endomorphy decreases with height in the case of both sexes. Conclusions: The men students' body build is dominated by mesomorphy and endomorphy, while the women students' - by endomorphy. Sexual dimorphism is best seen in the mesomorphic build.
