Abstract

Tradicionalno korištene metode za kinematičku analizu alpskoga skijanja imale su ograničenja vezana uz način prikupljanja i obrade podataka. Također analiza izmjerenih parametara, njihova interpretacija i implementacija u praksu bile su vrlo dugotrajne. Stoga je cilj ovoga rada uz primjenu relativno novije tehnologije, koja omogućava vrlo brzo prikupljanje podataka i njihovu analizu, utvrditi razlike u slalom zavoju izvedenom u 3 različite situacije. Analizirano je 20 varijabli za svaki pojedini slalom zavoj (lijevi i desni), 26 zavoja u svakoj situaciji. Sve zavoje izvodila je demonstratorica skijanja. Multivarijatnom analizom varijance utvrđena je značajna razlika između zavoja izvedenim u svim promatranim situacijama (F=71,3; p=0,00). Tukey post-hoc testom utvrđeno je da se zavoji izvođeni na skijaškom simulatoru razlikuju u svim varijablama od ostale 2 situacije, a slobodno skijanje od postavljenog koridora u sljedećim: (LR_HIP_AB, p=0,00; LCOM_R, p=0,00; LL_HIP_F, p=0,02; LL_HIP_AB, p=0,01; LCOM_L ,p=0,00; RL_KNEE_F, p=0,04). Korištenjem navedene tehnologije moguće je vrlo učinkovito koristiti znanstvene spoznaje u praksi na skijaškom terenu. Navedeno se odnosi na mlade sportaše, a i seniore u smislu ukazivanja na tehničke nedostatke temeljem objektivno utvrđenih modalnih vrijednosti. Samim time subjektivne procjene svode se na minimum, a izmjereni objektivni podaci se koriste u trenažnom procesu. Metodologija istraživanja i tehnologija korištena u ovome radu mogu doprinijeti novim spoznajama i smjerovima istraživanja u području biomehaničke analize u vrhunskom sportu.

Abstract (english)

Traditionally used methods for kinematic analysis of alpine skiing had limitations regarding data collecting and data processing. Also, analysis of measured parameters, interpretation and implementation in practice were long-term. Therefore, the aim of this paper is to determine differences of slalom turn between 3 situations by using this relatively new technology that allows fast dana collecting and analysis. 20 variables were analysed for each turn (left and right), 26 turns in each situation. All turns were made by national skiing demonstrator. The differences between slalom turns in observed situations were determined by using MANOVA (F=71,3; p=0,00). Using Tukey post-hoc test it was determined that turns made on simulator differ in every variable regarding 2 remaining situations and free skiing differs from corridor turns in following variables: (LR_HIP_AB, p=0,00; LCOM_R, p=0,00; LL_HIP_F, p=0,02; LL_HIP_AB, p=0,01; LCOM_L ,p=0,00; RL_KNEE_F, p=0,04). It is possible to use scientific knowledge very efficiently on an actual ski slope by using this technology. This concerns young athletes and also senior ones in terms of pointing out technical flaws based on objectively determined modal values. Subjective evaluation itself is reduced to minimum and measured data is used in training process. Methodology of research and technology used in this paper could contribute new scientific approaches in biomechanical research of top-level sport
