Introduction.  According to the point of view of many scientists, the continuous growth of achievements in sports, high competition in the international sports arena require a constant search for effective methodical, organizational and management solutions in the long-term training of athletes. So, we can conclude that the main content of all stages of sports selection is the prediction of the athlete's sports talent. Taking into account that the anthropometric parameters of athletes have been studied and are being studied to this day as well, but there are almost no works devoted to the study of the anatomical features of the femoral area of athletes of team sports.

Aim. To find out the anatomical features of the thigh circumference of football students of Bukovyna, followed by modeling for sports selection.

Materials and methods. A study was conducted on 86 student-football players of Bukovyna (the initial study was conducted during September-October 2021, and a repeat study of these same students in September-October 2022). The main group consisted of 46 (53.5%) football players and the control group - 40 (46.5%) students aged 16 to 18 years. All students were subjected to an anthropometric study, according to the method of P.P. Shaparenka (thigh circumference in the upper third, in the middle third and in the lower third, body weight, height). Welch's test was used to distribute the established parameters in both groups by gender. A paired t-test (paired-samples t-test) was performed to compare the respondents' indicators during the first measurement and the second one a year later. Statistical analysis of the obtained data was carried out using the licensed program RStudio.

Results. The comparisment of the thigh circumference parameters of football students of the main group between boys and girls in the initial study, found a difference between the indicators, since in all measurements the indicators of the boys are higher than those of the girls (±3.02 cm), especially when the circumference of the thigh in the lower third on the right is ±5.04 cm. The comparisment of the thigh circumference of the main group on the right and on the left, has established that in boys and girls the circumference in the upper third on the right is bigger by ±4.02 cm than on the left; the circumference thighs in the middle third on the left in girls and boys are bigger by ±10.01 cm; the circumference in the lower third in boys is bigger on the right by ±7.05 cm, in girls by ±5.04 cm. the comparison of thigh circumference in dynamics after a year, in football students reveals an obvious difference with the increase in thigh parameters: in the upper third of the right in boys and girls by ±1.5 cm, in the left in boys and girls by ±4.02 cm; in the middle third by ±4.5 cm in both genders on the right and by ±4.02 cm on the left; in the lower third by ±1.5 cm on the right in boys and by ±3.02 cm in girls, on the left by ±4.02 cm in both genders. By comparing the circumference between the right and left thighs in the main group, there is a difference, because in the upper the right third of girls and boys is ±1.5 cm more than the left; in the middle third from the left, boys have more by ±9.03 cm, girls by ±8.5 cm; in the lower third on the right, boys have more by ±4.5 cm, girls have more by ±4.02 cm.

Conclusions: Model for predicting thigh circumference in the upper third (right): Cpr=β1 + β2 + 0.493w – 0.135h, left: Cpl=β1 + β2 + 0.465w; in the middle (right): Cmr=β1 + β2 + 0.460w – 0.183h, on the left: Cml=β1 + β2 + 0.449w; in the lower third (right): Cdr=β1 + β2 + 0.418w, on the left: Cdl=β1 + β2 + 0.387w.
