The purpose of this master's thesis was to determine the connection between motor skills and elements of endurance in younger categories with performance in alpine skiing. The sample of subjects was included in the measurements taken at the Faculty of Sports, this included four competition categories aged 12 and 13 (U14; younger boys and younger girls) and 14 and 15 years (U16; older boys and older girls). We took into analysis the results of five motor ability variables that contained elements of endurance. Using the method of calculating correlations and multiple regression analysis, we determined the correlation and influence of the captured variables on the competitive performance in alpine skiing. In the entire sample of subjects, most of the motor skills variables used were statistically significantly related to performance in competitions. In both boys and girls, we proved a higher level of correlation of the whole set of selected variables with performance in alpine skiing in the younger category (U14) (boys 55,7%; girls 44,9%). The share of influence within the covered sets of variables was quite different in the considered categories of subjects. In the younger sample of boys (U14), the statistically significant influence of the Torso stabilization variable (STABTRUP/p = 0,002) should be highlighted in this respect. In the younger population of girls, the Bosco test variable (MMEBOSCO/p = 0,019) had the greatest impact on performance within the whole set of covered variables, while in the sample of older competitors the variable Pull ups with overhang (MZIBNP /p = 0,044) had the greatest impact. All the above calculations also coincide with the guidelines for fitness training of younger categories in alpine skiing.
