VALIDITY OF THE DIMENSIONAL CONFIGURATION OF THE REDUCED POTENTIAL PERFORMANCE MODEL IN SKI JUMPING

The aim of the study was to establish the validity of the dimensional configuration of the reduced po-tential performance model in ski jumping. Two performance models were prepared (models A and B), dif-fering only in terms of their method of determining the weights (dimensional configuration). Model A in-volves the dependent determination of weights while model B includes the independent determination of weights. The sample consisted of 104 Slovenian ski jumpers from the senior-men’s category, junior-men’s categories from 17 to 18 and from 15 to 16 years of age and three categories of boys from 13 to 14, from 11 to 12 and up to 10 years of age. Validity of the dimensional configuration of the reduced potential perform-ance model in ski jumping is different for the age categories. The tests of correlation between models A and competitive performance revealed that in some categories (senior-men (R = 0.74**) and boys aged up to 14 (R = 0.51**) the models correlated quite highly and even statistically significantly with actual competitive performance, while in others (junior-men aged up to 18 and 16) this correlation was slightly lower. The cor-relation between model B and competitive performance revealed that correlation was statistically significant (R = 0.49**) only by category boys up to 14 years of age.
