The somatotypological characteristic of acrobats in the literature is insufficiently disclosed, especially from the position of the role of sports selection, training and competitive activities in the formation of somatotype in athletes, whose professional activity is marked by coordination, rhythm and artistic movements, and the early onset of the impact of intense physical activity on their body. The purpose of the work is to establish the peculiarities of the components of the somatotype of acrobats with a high level of sportsmanship of prepubertal, pubertal and postpubertal age. We conducted a survey of 122 girls acrobats of high-level sports skills. As a control group, 126 girls were examined, who were not engaged in sports and studied in schools of Vinnytsia. The girls’ passport age was between 8 and 21 years old. In order to determine the biological age, we used the scheme Avtandilov G. G. (1990). The examined girls were divided into three groups according to the degree of biological maturity: prepubertal period (36 acrobats and 39 girls of the control group); puberty period (31 acrobats and 35 girls of the control group); postpubertal period (55 acrobats and 59 girls of the control group). The somatotypological study was performed according to the estimated modification of the Heath-Carters method (1990). The analysis of the obtained results was carried out in the licensed package “Statistica 5.5” using parametric methods of estimation of indicators. It was found that in the prepubertal period of the ontogenesis in the acrobat and in the girls who were not engaged in sports, the group somatotype was ecto-mesomorphic. In this period, the fatty component of the somatotype in acrobats was significantly lower, and mesomorphic - significantly higher than that of non-sports girls. In the puberty period, the somatotype in control and acrobats had distinct features of the ecto-mesomorphic type. It was found that acrobats in this period had a greater linearity of the body, as evidenced by the significantly higher values of their ectomorphic component of the somatotype. In addition, the size of the endomorphic component was significantly lower in athletes than in the control group. In the postpubertal period of ontogenesis, the F- and L-components were not significantly different, unlike in the previous period, which was characterized by intense puberty development. Acrobats only showed a significant predominance of the mesomorphic component of the somatotype. It can be concluded that the peculiarities of acrobatic sports activity in prepubertal, puberty and postpubertal age have the most significant effect on the development of the fatty and muscular components of the somatotype.
Determination of constitutional parameters that are inherent in highly skilled athletes of a particular sport can serve as reliable predictive markers during sport selection. But the last time an indisputable fact is the somatotypological conditionality of individual sizes that characterize the external structure of the body, and the visceral structures of the organism. The purpose of the work is to establish differences in the anthropometric dimensions between young women volleyball players of high level of athletic skill and non-sports young women belonging to the mesomorphic somatotype. On the base of the research center of the National Pirogov Memorial Medical University, we conducted an anthropo-somatotypological study of 127 female volleyball players of youth age (from 16 to 20 years) with a high level of athletic skill. Sports experience in all cases was greater than 3 years. From the database of research center of the National Pirogov Memorial Medical University was selected 140 practically healthy young women of the same age who were not engaged in sports. Anthropometric measurements were carried out using the method of V.V. Bunak (1941), somatotypological research – according to the estimated modification of the Heath-Carter method (1990). After the conducted somatotyping, it was found that 29 volleyball players and 33 non-sports young women belonged to the mesomorphic type of constitution. The analysis of the obtained results is carried out in the licensed package of Statistica 5.5 using nonparametric methods of evaluation of indicators. In the volleyball players of the mesomorphic somatotype, compared to young women who are not engaged in sports of the same constitutional type, we have found a significantly larger length of the body, the mass and area of the body surface, the height of the suprasternal, pubic, shoulder anthropometric points, chest cords, transverse mid and lower chest and sagittal middle-thigh diameters, intervertebral distance of the pelvis and its external conjugates. Relatively smaller in female volleyball players of mesomorphic type of physique was the thickness of the skin-fat folds under the shoulder blade. One can conclude that within the same somatotype there are significant changes in the anthropometric parameters, in particular total body and longitudinal, transverse, front and rear body dimensions, which is affected by the body of modern young women volleyball players with mesomorphic somatotype, under the influence of intensive loads.
It is reviewed last science data concerning oocyte maturation and pig embryo production in vitro. The aim of the work is to present new data concerning oocyte maturation and embryo production in vitro. Efficiency of different assistant reproductive methods can be improved by treatment of gametes and embryos with sublethal hydrostatic pressure. COCs denudation is better to perform 44 hours from the initiation of maturation procedure. Last 11 hours of maturation is better to perform in medium with decreased quantity of NaCl. Lipid content in oocyte significantly correlates with number of granulose cells per follicle. Larger size pre- and post pubertal oocytes are characterized by greater ability to development. Supplementation of culture medium with glycine leads to increase number of blastocyst cells. Addition of fibroblast growth factor to COCs culture medium benefits its development and blastocyst formation. COCs maturation normalization decreases polyspermy. Bringing endothelial growth factor in COCs medium culture increases rate of blastocyst formation. Different cells processes require different quantity of calcium ion oscillations. Temperature of liquid of preovulatory follicle can be indicator for oocyte quality. 14-days culture of COCs, recovered from early antral follicles, on polyacrylamide gel, results in achievement of larger size oocytes. It is improved method for optical observation of fertilization. It is worked out morula - blastocyst transportation for long distances. Introduction of Lysophosphatidic acid accelerates development of porcine embryos by activating formation of the blastocoel. Conclusion: last literature data show that row of different means of improvement for oocyte maturation and obtaining embryo in vitro is worked out.
