ANALIZA UČINKOVITOSTI OSNOVNEGA ZAVESLJAJA NA MIRNI VODI V KAJAKU ENOSEDU S TABLIČNIM RAČUNALNIKOM : diplomsko delo

Frančeškin, Maks (author), Čuk, Ivan (mentor)

Poglavitni cilj tega diplomskega dela je razčlenitev učinkovitosti osnovnega zaveslaja v kajaku za spust na divjih vodah in razlik v kakovosti tehnične izvedbe osnovnega zaveslaja med vrhunskim tekmovalcem in manj kakovostno tekmovalko. Meritve izvajamo na mirni oziroma stoječi vodi. Hkrati je namen dela tudi preizkus sistema meritev in razčlenitve v dejanskih pogojih, saj je cilj tovrstnih razčlenitev pogosta ter enostavna uporaba, ki vodi v stalni in neprekinjeni napredek v kakovosti tehnične izvedbe kajakaševega osnovnega zaveslaja. Temelj za uspešno izvedbo meritev in razčlenitev je vzpostavitev in poznavanje vrednosti izvedbe osnovnega zaveslaja predstavljenih in določenih v uvodnem poglavju tega dela. Meritve izvajamo z dvema merjencema na stoječem rokavu reke Ljubljanice. Izvajalec meritev z brega v bočni ravnini posname oba merjenca, ki na treh različnih območjih jakosti napora preveslata vnaprej določeno razdaljo. Za izvedbo meritev in razčlenitve uporabljamo tablični računalnik ter programe prilagojene uporabi na tej napravi. V delu prikažemo primerjavo vrednosti predstavljenih spremenljivk osnovnega zaveslaja ter prikažemo medsebojne povezave ter soodvisnosti le-teh. Ugotovili smo, da obstaja velika razlika v vrednostih, ki določajo stopnjo učinkovitosti osnovnega zaveslaja med vrhunskim tekmovalcem in manj kakovostno tekmovalko. Hkrati potrdimo, da je postopke meritev in razčlenitve veščemu izvajalcu možno opraviti v izjemno kratkem času, kar da delu veliko uporabno vrednost. Ob končani razčlenitvi zaključimo, da je napredek v stopnji kakovosti tehnične izvedbe osnovnega zaveslaja neprekinjeno in neskončno delovanje skozi celotno kajakaševo kariero.

• Title: Analysis of a wildwater kayak basic forward stroke on flatwater with the use of a tablet

Abstract

The main goal of the following thesis is the analysis of the wildwater kayak basic forward stroke efficiency on flatwater. The difference in technical profficiency between a high level athlete and a developing one is observed. In addition, the purpose of this paper is further testing of the measurements and analysis protocols in real world conditions, as the goal of the featured analysis analysis is a frequent and relatively simple use which results in a steady improvement of quality of paddler`s technique. Knowledge and understanding of kinematics and dynamics of the wildwater kayak basic forward stroke published and defined in the first chapter of this thesis are the key to performing a sucesful analysis. The measurements are performed by two athletes on a flat surface of the Ljubljanica river. A video of both athletes paddling at three different intensity zones over the same distance will be taken. A tablet will be used for measurements and analyisis of the wildwater kayak basic forward stroke. Furthermore, the analysis of the presented variables and their mutual dependencies and correlations will be looked into and explained. We came to a solid conclusion, that differences in values of the parameters between the two athlets of different skill levels exist. We also confirm, the the said process of measurements and analysis of wildwater kayak basic forward stroke can be performed in a very short duration of time, which gives this paper a real practical value. We conclude that the improvement in level of the technique in wildwater kayak basic forward stroke is a continious and neverending process throughout the whole athlete`s career.
