DYNAMIC COMPARISON THE THIGH LENGTH IN STUDENTS OF BUKOVYNA

Abstract

A paired t-test (paired-samples t-test) was performed to compare the respondents' indicators during the first and second measurements a year later. Statistical analysis of the obtained data was carried out using the licensed program RStudio. When testing the hypothesis that the average value of the length of the right thigh significantly increased, a significant increase in the length of the right thigh was found between the first (M=53.870, SD=4.098) and the second (M=54.319, SD=4.118) measurements; t(68)= -6.704, p<0.001. The average value of the length of the left thigh also increased significantly, and there was a significant increase in the length of the left thigh between the first (M=53.855, SD=4.237) and the second (M=54.478, SD=4.161) measurements; t(68)= -5.328, p<0.001. A comparison of the length of the thigh in the dynamics after a year; in student-athletes of the main group showed a difference in the increase of the length of the thigh in 2022 compared to 2021 (±0.48-0.62 cm). According to the comparison of the left and right thigh during the second measurement of student-athletes, no significant difference in the average length of the right and left thigh was found (right – 54.31±2.04 cm, left – 54.47±2.04 cm). A significant predictor of thigh length is height. A model was derived for predicting the length of the right thigh Lr = 0.308 h and the left Ll = 0.309 h, where L is the length of the thigh, h is height. The coefficient of determination is 99.8%.
