Порівняння довжин стегна у студентів закладів вищої освіти Буковини залежно від виду спорту

Abstract

The purpose of the study is to determine the length of the thighs of students of higher educational institutions of Bukovyna depending on the kind of sport, followed by building a forecasting model. Materials and methods. The research was conducted on young men and women of higher educational institutions of Bukovyna aged 16 to 21 years. Of these, 83 (64.4%) were boys and 46 (35.6%) were girls. All respondents are divided into two groups: the main group – 89 (69%) and control – 40 (31%) students. Students of the main group were engaged in the following sports: football – 40 (44.9%) students, volleyball – 18 (20.3%), tennis – 10 (11.2%), fitness – 9 (10.1%), basketball – 7 (7.9%), freestyle wrestling – 5 (5.6%). All students were subjected to anthropometric research, according to the method of V. V. Bunak in the modification of P. P. Shaparenko. Statistical analysis of the data was performed using a licensed program RStudio. Results. The data obtained show that the difference in the length of the right thigh of boys and girls of the main group on average is not very noticeable. Welch's t-test shows that the difference is significant: t (36.724) = - 2.120, p = 0.041 <0.05. In the control group, there is an average significant difference in the length of the right thigh of boys and girls. This is also evidenced by the Welch’s t-test: t (36.501) = - 2.183, p = 0.036 <0.05. The result of the distribution of the length of the left thigh of the respondents of the main group by gender shows that on average there is a significant difference in the length of the left thigh of boys and girls. Welch's t-test shows the significance of the difference: t (35.822) = - 2.146, p = 0.039 <0.05. When distributing the length of the left thigh of the respondents in the gender control group, it seems that on average there is a significant difference in the length of the left thigh of boys and girls. This is also evidenced by the Welch’s t-test: t (27.596) = - 2.141, p = 0.041 <0.05. Conclusion. By comparing the length of the thighs of the studied students of the main group, depending on the sport, it shows that students who play volleyball have the longest thigh length: right – 55.00 ± 2.0 cm, left – 55.53 ± 2.0 cm; and in football – right thigh is 53.97 ± 2.0 cm, left – 53.92 ± 2.0 cm), slightly shorter thighs are of those who fight: right – 53.40 ± 2.0 cm, left – 53.47 ± 2.0 cm and tennis: right – 53.60 ± 2.0 cm, left – 53.50 ± 2.0 cm; then basketball players: right – 52.85 ± 2.0 cm, left – 52.63 ± 2.0 cm, and the shortest length of the thigh are of students engaged in fitness: right – 51.11 ± 2.0 cm, left – 51.30 ± 2.0 cm). An important factor for thigh length is height (based on regression analysis). Model for predicting the length of the right thigh is y = 0.239 * x, where y is the length of the right thigh, x is the height. The coefficient of determination is 0.996. Model for predicting the length of the left thigh is y = 0.309 * x, where y is the length of the left thigh, x is the height. The coefficient of determination is 0.991
