Research results and discussion: At the first stage of the study, we identified the intergroup variability of morphological characteristics of urban schoolchildren aged 15-16 in Karshi and schoolchildren living in the village of Nekuz in Kashkadarya region. Differences in indicators of total body size have been established. If urban schoolchildren have a body length of 171.9±6.7 cm, body weight - 58.9±9.2 kg, chest circumference – 86.9±9.2 cm, then schoolchildren in the village of Nekuz have a body length of 170.5±8.16 cm, weight -56.9±9.05, and chest circumference -82.1±6.05cm, that is, according to physical development, there is a slight lag in body length by 1.4 cm, body weight is 2 kg, chest circumference is lower by 4.8 cm, that is, less than that of urban schoolchildren. It should be pointed out that about 5% of urban schoolchildren are engaged in sports sections, but for the rest of the students, physical activity is limited to physical education classes in accordance with the school curriculum.

Dynamics of changes in physical fitness of schoolchildren living in urban and rural areas (n=46)
Intergroup pairwise differences were recorded for the compared urban and rural schoolchildren and in terms of physical fitness. During the experiment, rural schoolchildren from the village of Nekuz demonstrated higher results in terms of the level of development of physical qualities. Thus, statistically significant differences were found in the triple jump test. The increase in this test among urban schoolchildren was -1.6%, and among schoolchildren with.Non–university - 6.9%.(Table 1). "Long jump from a place" demonstrating the level of development of speed and strength qualities, rural schoolchildren showed a higher result compared to urban schoolchildren. The increase in the result on this test was -165.0± 2.2 cm for urban children, and the jump value was - 172.0± 2.2 cm for rural schoolchildren. In the test, the increase in the development of strength qualities among schoolchildren in Karshi was -2.1%, and among rural schoolchildren it reached - 3.7%, that is, the indicator is higher for strength capabilities among schoolchildren living in rural areas, although slightly. The quality of dexterity is demonstrated in the "rope climbing" test. For the compared groups, the values of this indicator turned out to be almost the same for schoolchildren living in Karshi, their result was – 10.0 ± 0.30 s, and for schoolchildren of the village of Nekuz, "rope climbing" the result was - 9.7 ± 0.20 s, that is, the difference is insignificant. In the "Pull-up on the crossbar" test, the difference in the value of strength qualities at the initial stage was 1.7% more than in urban schoolchildren. However, at the final stage of the experiment, the difference between urban and rural schoolchildren was 0.5% in favor of rural schoolchildren. The speed test was evaluated based on the results of running at 30 m. For this test, the result of the increase was higher in rural schoolchildren and amounted to -3.7%. Thus, some disproportion between the level of physical development and physical fitness of the compared groups of schoolchildren was revealed. Thus, according to the level of physical development, urban schoolchildren are characterized by increased body weight, higher height, and greater chest circumference compared to rural schoolchildren. However, according to the level of physical fitness in rural schoolchildren, the maximum number of statistically significant differences in the level of development of a number of physical qualities has been established, although according to some test indicators, minor differences were found between the compared groups – in the "pull-up on the crossbar" test.
