Postavitev nog pri udarcih v odvisnosti od časa in lokacije udarca pri vrhunskih igralcih skvoša : magistrsko delo

Rojnik, Sara (author), Vučković, Goran (mentor)

Tehnika v skvošu je sestavljena iz posameznih tehničnih elementov, ki so medsebojno povezani in soodvisni ter se navezujejo v ponovljivih ciklih. Začetno stanje cikla nastopi z ustreznim postavljanjem igralca na področju T, na katerem igralec ob udarcu tekmeca izvaja pripravo na gibanje, sledi gibanje do žoge, ki ga igralec zaključi s postavitvijo pri udarcu. Kljub temu da je od postavitve pri udarcu precej odvisna uspešnost samega udarca, pa v strokovni in znanstveni literaturi ni zaslediti dela, ki bi podrobneje obravnavala tehniko skvoša z vidika postavitve nog pri udarcih. Zato je bil predmet in problem pričujoče raziskave analizirati postavitev nog pri udarcih v različnih delih igrišča in obenem ugotoviti vpliv predhodnega udarca in časa na postavitev igralcev pri udarcih v področjih v zadnjem delu igrišča. Rezultate smo pridobili na vzorcu 19 tekem mednarodnega turnirja British Grand Prix (Manchester, 2011). Vzorec igralcev je sestavljalo 21 igralcev, ki so v času turnirja zasedali od 1. do 65. mesta na svetovni jakostni lestvici. Postavitev pri udarcu smo razdelili na sonožno in v izpadni korak, pri čemer je bila slednja lahko pravilna oziroma nepravilna. Rezultate smo pridobili s pomočjo sledilnega sistema Tracker, ki je bil razvit na Fakulteti za elektrotehniko (UL). Vpliv predhodnega udarca in časa ter razlike med postavitvijo v posameznem področju igrišča smo ugotavljali s pomočjo metode hi-kvadrat v statističnem programu IBM SPSS. Igralci so v sprednjem delu igrišča v več kot 95-odstotnem deležu udarce izvedli s postavitvijo v izpadni korak. Ta postavitev je bila pogostejša tudi pri udarcih v področjih bližje stranskim stenam. Igralci so na bekend strani statistično značilno večkrat žogo udarili s pravilno postavitvijo v izpadni korak, na forhend strani pa z nepravilno postavitvijo. V zadnjem delu igrišča je bila ugotovljena statistično značilna razlika v postavitvi pri udarcu, pri čemer je na rezultate vplivala stran igrišča, predhodni udarec tekmeca in čas, ki ga je igralec imel na voljo za lastni odgovor oziroma udarec.

• Title: Placement of feet at shots in correlation of time and location of shot of elite squash players

Abstract

The squash technique consists of separate interconnected and interdependent technical elements that relate in repeatable cycles. The initial state of the cycle begins with the appropriate position of the player in the T area where the player prepares for the movement when the opponent hits the ball, followed by a movement to the ball, which the player completes in the hitting position. Although the success of the hit itself depends on the position, the impact of leg position in the squash technique has not yet been thoroughly discussed in the academic and the scientific literature. Therefore, this study aimed to analyze the position of the legs when hitting the ball in different parts of the field and at the same time to determine the impact of the previous hit and the impact of time on the position of players when hitting the ball in areas in the back of the field. The results were obtained on a sample of 19 matches of the British Grand Prix (Manchester, 2011). The sample of players consisted of 21 players that ranked 1st to 65th in the world rankings during each tournament. The hitting position of the player was divided into the two-feet position and the lunge position, whereby the latter may have been correct or incorrect. The results were obtained using the Tracker tracking system, which was developed at the Faculty of Electrical Engineering at the University of Ljubljana. The influence of the previous hit and the time, as well as the difference between the position in an individual area of the court, was determined using the Chi-square method in SPSS Statistics (IBM). In the front part of the field, the players took more than 95% of the shots by placing their legs in the lunge position. This position was also more common with hits in areas closer to the side walls. Statistically, the players hit the ball more often on the backend side correctly in the lunge position. However, on the forehand side, the players hit the ball more often incorrectly in the lunge position. In the back part of the court, a statistically significant difference in the hitting position was found, where the results were influenced by the side of the court, the opponent's previous hit and the time the player had for his response.
