Overview

The purpose of the research study was to determine the structure of the competitive performance variables of male and female ski jumpers who participated in the second series of the competition on the smaller HS106m ski jumping hill at the Beijing 2022 Winter Olympics. The dependent criterion variable was the length of the jump. The following independent variables were included: in-run velocity, flight velocity at a point 30 m after the end of the take-off table, velocity of movement of the jumper at landing, V-angle between the skis at a point 30 m after the end of the take-off table and wind speed. Descriptive statistics, correlation analysis, and factor analysis were used to analyze the data. Differences in the dependent criterion variable (jump length) were much higher in women (M = 85 m, SD = 8.3 m) than in men (M = 98 m, SD = 3.9 m). At a fairly similar in-run velocity, men achieved an average of 13 m longer final jump than women. A statistically significant correlation between jump length and wind speed was observed in males (r = .42). In females, the variables in-run velocity (r = .59) and landing speed (r = .59) were significantly corelated with jump length. The multiple correlation showed a much higher correlation of independent variables in women (Mult R = .78; Sig R = 0.00) than in men (Mult R = .54; Sig R = 0.23). The overall competitive performance factor for men and women was largely determined by the jump length and style scores variables. The wind speed factor was completely independent of the other independent variables. The research showed a significant difference in the average quality level of competitive performance in male and female category. In particular, women had a much higher variability in competitive performance than men. The results of the survey confirmed that for a top achievement, in addition to the length of the jump, the score for style is also important. Based on this important knowledge for practice, coaches should pay more attention to the development of the aesthetic component of ski jumping technique. Namen raziskovalne študije je bil ugotoviti strukturospremenljivk tekmovalne uspešnosti smučarjev skakalcev in smučark skakalk, ki so nastopili v drugi serijitekmovanja na manjši skakalnici HS106m na zimskiholimpijskih igrah v Pekingu 2022. Odvisno kriterijskospremenljivko je predstavljala dolžina skoka. Medneodvisne spremenljivke so bile uvrščene: zaletna hitrost, hitrost leta v točki 30 m za robom odskočišča, hitrost ob doskoku, kot med smučkama v točki 30 m za robom odskočišča in hitrost vetra. Za analizo podatkov je bila uporabljena opisna statistika, korelacijska analiza infaktorska analiza. Razlike pri odvisni kriterijskispremenljivki (dolžina skoka) so bile precej višje priženskah (M = 85 m, SD = 8,3 m) kot pri moških (M = 98m, SD = 3,9 m). Pri podobni zaletni hitrosti so moškidosegli v povprečju 13 m daljši finalni skok kot ženske.Pri moških je bila ugotovljena statistično pomembnakorelacija med dolžino skoka in hitrostjo vetra (r = 0,42).Pri ženskah sta bili z dolžino skoka značilno povezanispremenljivki zaletna hitrost (r = 0,59) in hitrost obdoskoku (r =0,59). Z multiplo korelacijo je bilaugotovljena precej višja povezanost neodvisnihspremenljivk pri ženskah (Mult R = 0,78; Sig R = 0,00) kotpri moških (Mult R = 0,54; Sig R = 0,23). Faktortekmovalne uspešnosti sta tako pri moških kot pri ženskah v največji meri skupno determinirali spremenljivki dolžina skoka in stilne ocene. Faktor hitrosti vetra je bil neodvisen od ostalih neodvisnih spremenljivk. Raziskava je pokazala značilno razliko v povprečni kakovostni ravni tekmovalne uspešnosti v moški in ženski konkurenci. Še zlasti je bilapri ženskah prisotna precej višja variabilnost tekmovalneuspešnosti kot pri moških. Rezultati raziskave so potrdili,da je za vrhunski dosežek, poleg dolžine skoka pomembna tudi ocena za slog. Na osnovi tega pomembnega spoznanja za prakso, bi morali trenerji posvetiti več pozornosti razvoju estetske komponente tehnike smučarskega skoka.
