The main goal of the study is to assess the level of physical development and maturity of schoolgirls and teenage girls involved in sports. Materials and methods: 2001 students involved in sports and teenage girls aged 11 to 15 years studying in 2 sports schools, 1 high school and 2 colleges in the Andijan region from 2019 to 2022 were examined. Anthropometric indicators reflecting the maturity of physical development were selected as the subject of the study, namely: the Brugsch index, Erisman index, Broca index, hemodynamic index, Livi index, body mass index, another indicator reflecting the level of maturity - the ratio of waist circumference/hip circumference. Research results. Index indicators of physical development/maturity of schoolgirls and teenage girls were studied and determined in research groups (the results of the analysis are presented in Table 1 and Figure 2 in the Appendix). The Brugsch index, which expresses the maturity of physical development, was determined in the studied girls as follows: in the main group - 46.07±6.10, in the comparison group - 45.08±5.10 and in the control group - 47.99±6.29 [R1- 2˂0.05; P1-3 ˂0.001; R2-3 ˂ 0.001]. Conclusion This information is important when assessing the maturity and age of schoolgirls and adolescent athletes. Their timely correction is of great importance in the prevention and treatment of reproductive and somatic acute and chronic diseases.
