Sažetak
Vertical jump is seen as the main motor skill in basketball, on which the final result largely depends. The research was conducted with the aim of identifying the connection between morphological characteristics and the manifestation of tests for assessing the explosive power of lower limbs of adolescent basketball players (14.99±0.82 years of age). The assessment of the explosive power of lower limbs was done using the tensiometer Quattro Jump - Kistler Portable performance analysis system 2019, Type 9290DD Switzerland, and standardized tests countermovement jump and squat jump were applied. The system of predictor variables included the factor of longitudinal skeletal dimensions, transverse skeletal dimensions, body volume and weight factor, and subcutaneous adipose tissue factor. All anthropometric measures were strictly taken in accordance with IBP standards. The results of the regression analysis indicated that the system of predictor variables had a statistically significant effect on the manifestation of explosive power of lower limbs in the variable countermovement jump (P=0.05) and squat jump (P=0.01). High values of the coefficients of determination in both cases explain from 92% to 97% of the total variation. The predictor variable Wrist diameter (Beta = -0.78) had the highest significant negative correlation in the countermovement jump test, while the following predictor variables also had the highest significant negative correlation with the squat jump criterion: Chest circumference (Beta=-1.07), Body weight (Beta=-060) and Thigh circumference (Beta=-0.39). Furthermore, negative correlations of variables for the assessment of transverse skeletal dimensions in young basketball players and negative linear correlation of variables for the assessment of subcutaneous adipose tissue in both criteria were observed. The authors recommend dividing athletes by positions they play in, in order to obtain more accurate information about the negative correlation between morphological characteristics and vertical jump tests.
