Section GROWTH and DEVELOPMENT HORMONAL STATUS AS A FACTOR OF DIFFERENTIATION OF RATES OF DEVELOPMENT Titova Elena, Savostyanova Evgeniya, Makhalin Adu, Savchenko Elena Russian State University of Physical Education, Sports, Youth and Tourism, Moscow, Russia The problem of individually typological patterns of growth in connection with the general physical development is one of the most important issue in modern auxology, physical and age morphology. <...> This study applies the biotypological approach to the analysis of individual variability of hormonal status in pubertal males. <...> A number of hormones, the most informative for this age, were selected: sex hormones and growth hormone (GH) – leading anabolic factors of growth and development in the pubertal period, and cortisol as their antagonist. <...> As the most informative criterion of biological age, stages of sexual development were used, particularly of such a character as pubic hair (P). <...> There are marked differences in the ratio of testosterone:cortisol: it increases more than twice from the stage P1-2 to P4. <...> The ratio of estradiol: testosterone is reduced from the stage P1-2 to P4 more than twice. <...> An apparent trend towards stabilization in the level of GH between stages P3 and P4 is consistent with the literature data. <...> Anabolic trends in the endocrine formula in connection with the biological age (absolute and relative increase of testosterone in relation to cortisol and estradiol) are accompanied by the corresponding changes in the body build – strong development of endo- and mesomorphic components. <...> The results clearly show the connection of the accelerated type of development with the highest level of testosterone and the minimal ratio of estradiol-testosterone. <...> Key words: endocrine formula, biological age, auxology Contact information: Titova Elena Petrovna, e-mail: elpetat@yandex.ru, PHYSICAL DEVELOPMENT OF CHILDREN IN MOSCOW REGION AND SOME STATISTICAL INDICATORS IN 1976–1980S Zubareva Vera, Permyakova Ekaterina Research Institute and Museum of Anthropology, Lomonosov Moscow State University, Moscow, Russia Patterns of physical development of schoolchildren in different areas of Moscow Region (Podolsk, Istra, Dedovsk, Solnechnogorsk, Zagorsk, Golitsino, 1985, n=3512) with additional data of Tchulkovo, Ramenskiy district (1976, n=842) were compared. <...> Height, chest circumference, shoulder and pelvic diameters were studied; questioning of parents was conducted. <...> The results of the 10-year study (1976–1985) show some reducing <...>
