There is no common opinion, if the final height of female artistic gymnasts is jeopardized due to excessive training from early childhood. The aim of this master thesis is to compare a trend in human height of artistic gymnasts in three consecutive generations. Auxologic and related information were obtained from 49 elite artistic gymnasts via questionnaire. All were the members of national team. We figured out that artistic gymnasts are statistically smaller than their same-age peers. However, all of them have reached their genetically determined growth potential. The final height of artistic gymnasts across generations was increasing as well as the average female population. According to growth charts, constitutional delay is typical for artistic gymnasts. The age of menarche was statistically higher in the two youngest generations in comparison with the average age of their peers. According to our results, artistic gymnasts are not smaller due to excessive training from childhood, but on the grounds of genetic predisposition for small stature, which is favorable for this sport.

Thesis aims to analyze some auxological aspects of menarche in a sample of peripubertal school-aged Prague girls. Sample PRAHA 2012 consists of 293 girls from Prague within the age ranging from 11,00 - 14,99 years. Ascertained median age of menarche 12,4 years is significantly lower (p = 0,0004) than median of Prague population - 13,04 years, respectively lower than median age of menarche of Czech population - 13,00 years according to data from the last national anthropological survey (CAV 2001). Our investigation suggests a "break off" in long-term stagnation age of menarche (minus 0,6 year) at least in a urban population in Czech Republic. According to our findings deceleration age of menarche wasn't accompanied by increase of average body height or other nutritional characteristics (body weight, BMI, arm circumference, thickness of skinfolds) in comparison with actual pediatrics standards. Though, there is a clearly evidence that participant's body composition affected age of menarche. A comparison of premenarcheal (n = 139) and postmenarcheal (n = 154) girls of the same age showed statistically significant elevated values in body weight (42,5 kg, 47,6 kg vs 56,3 kg, 54,1 kg), BMI (17,6 kg/mš, 18,3kg/mš vs 21,3 kg/mš, 20,7 kg/mš) and percentage of body fat (19,4%, 19,7% vs 24,5% a 23,1%) at...
