DYNAMICS OF ANTHROPOMETRIC INDICATORS IN GIRLS WITH DIFFERENT SOMATOTYPE

Abstract

The dynamics of the growth and development processes are much related to the characteristics of the constitution. The aim of the research was to study the dynamics of anthropometric indicators in girls aged 7-12 years with different somatotype. 1527 girls aged 7-12 years studying in schools of Yaroslavl were examined. The somatotype was evaluated by summing centile interval numbers of body length, body weight and chest circumference. It was revealed that schoolgirls with a mesosomatotype prevailed in all age groups. The girls’ proportion with a macrosomatotype increased with age and reached maximum values at 11 years (45.5 %). Body length, body weight and chest circumference statistically significantly increased from microsomatotype to macromosatotype in all age groups. Anthropometric indicators were statistically significantly increased with age only in meso and macrosomatotype. A significant increase of anthropometric indicators in microsomatics was noted in individual age periods. It was found that the growth rates in microsomatics was statistically significantly lower than in meso and macrosomatotype. The increases of body length, body weight and chest circumference at different age periods were established. The intensive growth maxima of anthropometric indicators in girls with different somatotypes were not same.
