Study of somatic traits of linear proporcionality in boys at the age of 11 to 14 years.
Němcová, Kateřina ; Sedlak, Petr (advisor) ; Zemková, Daniela (referee)
This study brings the information on linear body proportionality of pubescent boys. The body linear proportionality was validated by using the SD scores gained from the measured data and by validating the individual proportionality with help of natural Percal indices. Each child was considered according to his biological maturity by using KEI index. For rating of the growth of individual and his proportionality, the compliance of KEI index and the difference of height and chronological age were validated. The considering of those biological trends made it possible to separate the individuals with possible physiological variant of normal growth from the individuals with suspective growth pathology. The set included 346 boys in the age of 10-14 years, after replacing of disproportional individuals from the study. For evaluation of changes in the linear body proportionality the linear somatic markers with high degree of accuracy and reliability of measurement were chosen and the descriptional statistics were set to these parameters and to their indices. Comparing with reference sets the changes in proportional relations in year and half-year cathegories were described. Descriptive statistics of subischial length to sitting height index and arm span to body height index are not part of the referencial standard...
