COMPARATIVE DESCRIPTION OF PHYSICAL DEVELOPMENT OF CHILDREN OF JUNIOR SCHOOL AGE USING BODY WEIGHT, HEIGHT AND CHEST CIRCUMFERENCE INDICATORS

In this research work, the body weight (kg), height (cm) and chest circumference (cm) values of junior high school students (7-10 years old) in secondary schools located in some districts of Andijan region of the Republic of Uzbekistan were analyzed based on comparison. Generally accepted anthropometric research methods were used in the research. In the researches, it was found that body weight (kg), height (cm) and chest circumference index value (cm) increase in the age range of 7-10 years in secondary schools located in sub-mountainous climate-geographical zones. Based on the obtained results, it was noted that it is important to take into account the influence of factors related to climate-geographical conditions in the development of a complex of medical/pedagogical corrections and preventive measures in the development of anthropometric parameters for students of junior school age (ages 7-10).
