Vpliv zamaha z rokami na količino obrata pri skoku stegnjeno : magistrsko delo

Saje, Petra (author), Čuk, Ivan (mentor)

Namen magistrskega dela je predstaviti ugotovitve raziskave o vplivu zamaha z rokami na količino obrata pri skoku stegnjeno. Cilj je bil ugotoviti značilnosti posameznega skoka z določenimi zamahi in razlike med različnimi izvedbami skokov. Prav tako se je zabeležilo napake, ki so bile prisotne pri skokih med meritvami. Vzorec merjencev so predstavljali skoki stegnjeno z obratom (N=288) s tremi različnimi zamahi z rokami, ki so jih izvedli študentje (N=32) 1. letnika Fakultete za šport, Univerze v Ljubljani. Prvi je bil skok stegnjeno z obratom z rokami v priročenju (brez zamaha), drugi z zamahom iz odročenja v priročenje in tretji z zamahom rok iz zaročenja v vzročenje. Dva neodvisna dejavnika sta bila čas leta in količina obratov. Ugotovljeno je bilo, da so imeli najdaljši čas leta skoki stegnjeno z obratom z zamahom iz zaročenja v vzročenje, najkrajši čas leta pa skoki stegnjeno z obratom brez zamaha z rokami. Največja količina obrata se je proizvedla pri skokih stegnjeno z obratom z zamahom iz odročenja v priročenje, najmanjša količina obrata pa pri skokih stegnjeno z obratom z zamahom iz zaročenja v vzročenje. Za najbolj učinkovit zamah z rokami se je izkazal zamah iz odročenja v priročenje. Najpogostejše napake, ki so se pojavile med izvedbo skokov stegnjeno z obrati so bile nagnjeno telo med letom, doskočišče je izven središča in vrtenje po pristanku. Ugotovitve in priporočila lahko vaditeljem in ostalim delavcem v športu pomagajo pri metodičnih postopkih učenja skokov z obrati.

• Title: The Effect of Arm Swing on the Amount of Turning in the Vertical Jump

Abstract

The aim of this master's thesis is to present the results of a study on the influence of arm swings on rotation during the vertical jump. The aim was to determine the characteristics of the individual jumps with specific arm swings and the differences between different jump executions. In addition, the errors occurring during the jumps were recorded in the measurements. The sample consisted of jumps with rotation (N=288) with three different arm swings, performed by first-year students (N=32) of the Faculty of Sport, University of Ljubljana. The first was a straight jump with rotation with the closearm (without arm swing), the second with arm swing from the sidearm to the closearm, and the third with arm swing from the reararm to uparm. Two independent factors were the flight time and the extent of the rotation. It was found that the longest flight time occurred in jumps with rotation with arm swing from the backarm to the uparm, and the shortest flight time occurred in jumps with rotation without arm swing (closearm). The greatest rotation was produced in jumps with arm swing from the sidearm to the closearm, the smallest rotation in jumps with arm swing from the reararm to the uparm. The most effective arm swing was the swing from the side arm to the closearm. The most common errors that occurred when performing jumps with rotations were a tilted body during flight, an off-centre landing, and a rotation upon landing. The results and recommendations can help coaches and other sports professionals in the methodological processes of teaching jumps with twists.
