The purpose of the study was to establish of upper limbs length of students of higher educational institutions of Bukovyna depending on the sport type with the further construction of forecasting model. Materials and methods. The research was conducted on 132 students of the first and second years of higher education institutions of Bukovyna aged from16 to 18. Of them, 86 (65.15%) were boys and 46 (34.85%) girls. The main group consisted of 92 (69.70%) students and the control group – 40 (30.30%) students. Among the students of the main group, there are 65 (70.65%) boys and 27 (29.35%) girls. The control group consisted of 21 (52.5%) boys and 19 (47.5%) girls. Students of the main group were engaged in the following sport types: football, volleyball, handball, basketball. Students of the control group did not additionally do sports, except for hours of physical education, in accordance with the curriculum. All students were subjected to an anthropometric study according to the method of V. V. Bunak modified by P. P. Shaparenkо. Anthropometric examination included determination of total and partial parameters. Results and discussion. According to the results of the study, that included the distribution of the length of the right and left upper limbs for gender, there was a significant difference in the average length of young boys and young girls in the main group. This is also evidenced by Welch's t-test: t (49.3) = – 7.253, p < 0.05. The result of the distribution of the length of the right and left upper limbs in the control group for gender also indicates that there was a significant difference in the length of the upper limb of young boys and young girls of the control group on average. This was also confirmed by Welch's t-test: t (25.971) = – 5.670, p < 0.05 (right upper extremity) and t (26.175) = – 5.754, p < 0.05 (left upper extremity). Taking into account the results of the distribution of the lengths of the upper limbs depending on the sport type, it shows that there was a significant difference in the average value of the length depending on the sport type. Since p = 0.25 < 0.05, the difference between the medians of the groups is statistically significant. When comparing the lengths of both upper limbs of the studied young boys and young girls, no significant difference in the average length of the right and left upper limbs was found t (255.92) = – 0.172, p = 0.864. Conclusion. By comparing the length of the right and left upper limbs of the studied students of the main group, depending on the sport type, there was a significant difference in the average value (football players have the smallest length of the upper limbs: right – 69.77 ± 2.0 cm, of them 70.39 ± 2.00 cm in young boys and 67.90 ± 2.00 cm in young girls, left – 70.28 ± 2.0 cm, of them 71.41 ± 2.00 cm in young boys and 68.72 ± 2.00 cm in young girls, while volleyball players have the largest: right – 76.20 ± 2.0 cm, of them 77.32 ± 2.00 cm in young boys and 74.22 ± 2.00 cm in young girls, and left – 77.00 ± 2.0 cm, of them 78.43 ± 2.00 cm in young boys and 75.92 ± 2.00 cm in young girls). A significant factor for the length of both upper limbs is height. A model for predicting the length of the upper limbs was derived: y = 0.422 * x, (where y – the length of the right upper limb, x – height)
