Experts model of exercises for the correction of characteristic mistakes made during the execution of dynamic parallel ski turn

The purpose of the present study was to investigate the formation of an expert model of the most important methodical exercises for correction the mistake Slipping, manifested through execution of dynamic parallel ski turn, and the hierarchical classification of the expert model a two-stage research was conducted. In the first phase of the research with the aim of forming an expert model of the most important methodical exercises for correction the mistake Slipping manifested through execution of dynamic parallel ski turn participated of 20 skiing experts aged 25 to 45. By means of email and coordinated by the paper author, the experts first defined a model of 13 methodical exercises and then, on a scale from 1 to 5, selected the five most important exercises. In accordance with the objective set by the study a nonparametric chi - square test () was used. Based on the obtained values of testing difference between the experts in the evaluation of the five most important methodical exercises was not established (=14, 22 ; p=0, 22). The expert model of most important methodical exercises for correction of the Slipping mistake consisting of: Hands on knees, External arm on side and other on internal knee, Hands on hips, Sticks with hands on sides and Pushing the external shoulder in turn. In the second phase of the research with the aim of forming the hierarchical classification of the expert model of the most important methodical exercises for correction of the Slipping mistake correctional correction exercises manifested through execution of dynamic parallel ski turn, 307 ski experts various levels of ski knowledge participated. Respondents’ mission was to rank the exercises based on their opinions of how important they are. Total amounts of rank sums (ΣR) were calculated, as well as the Kruskal-Wallis test (H- test), and belonging levels of significance (p) with the purpose of comparing the significance of diversity between rank sums and expert model. The statistically significant difference was found between the sum of the sum of the sum of the rank (ΣR) of the most effective exercises for the correction of the characteristic mistake Slipping (H=210, 37, p <0, 001). The results of the two phases investigate of this research provide valuable information on the methodological settings of dynamic parallel ski turn. In future research it is necessary to evaluate the formed expert model of the most important methodical exercises, as well as its hierarchical classification, in different groups of respondents.
