Magistrsko delo obravnava vpliv utrujanja na tehniko zaveslaja pri veslanju na nepremičnem veslalniku Concept2. Namen raziskave je bil ugotoviti, kako utrujenost vpliva na biomehanske značilnosti zaveslaja med 2000-metrsko veslaško meritvijo. Posebno pozornost smo namenili spremembam dolžine zaveslaja, položaja ročaja v zaključku zračnega dela zaveslaja, časovni usklajenosti gibanja trupa glede na dejavni del odriva nog ter spremembam kota med glavo, ramo in kolkom v zaključnem delu zaveslaja. Dodatno smo spremljali tudi silo na stopalih ter čas do dosežene največje sile. Raziskava je bila izvedena kot študij primera na enem merjencu. Gibanje smo razčlenili s pomočjo videoposnetkov in programa Kinovea, podatke pa statistično obdelali s pomočjo programa Microsoft Excel. Za preverjanje razlik med posameznimi obdobji zaveslajev smo uporabili zaporedje t-testov. Rezultati raziskave kažejo, da utrujenost vpliva na biomehaniko zaveslaja, vendar spremembe niso bile enake pri vseh spremljanih spremenljivkah. Pri dolžini zaveslaja rezultati niso pokazali postopnega zmanjševanja skozi celotno meritev, saj je do izrazitejšega skrajšanja prišlo predvsem v zaključnem delu meritve. Pri položaju ročaja in časovni usklajenosti gibanja trupa glede na dejavni del odriva nog so bile sicer ugotovljene statistično značilne razlike, vendar spremembe niso potekale v predvideni smeri. Rezultati so pokazali tudi statistično značilne spremembe kota med glavo, ramo in kolkom, kar kaže na vpliv utrujenosti na položaj zgornjega dela telesa med veslanjem. Dodatne meritve sile na stopalih so pokazale podoben vzorec sprememb pri levem in desnem stopalu, medtem ko so bile večje spremembe časa do največje sile ugotovljene predvsem pri levem stopalu. Ugotovitve raziskave kažejo, da utrujenost vpliva predvsem na gibanje trupa in zgornjega dela telesa ter povzroča prilagoditve tehnike zaveslaja med dolgotrajnim naporom. Magistrsko delo predstavlja dodatni vpogled v povezavo med utrujenostjo in biomehanskimi spremembami tehnike zaveslaja ter izhodišče za nadaljnje raziskovanje tega področja

• Title: How fatigue affects rowing stroke technique (a case study)

Abstract

This master’s thesis examines the impact of fatigue on rowing stroke technique during rowing on a stationary Concept2 rowing ergometer. The aim of the study was to determine how fatigue affects the biomechanical characteristics of the rowing stroke during a 2000-meter rowing test. Particular attention was given to changes in stroke length, handle position at the finish of the recovery phase, temporal coordination of trunk movement relative to the active leg drive, and changes in the angle between the head, shoulder, and hip at the finish of the drive phase. Additional measurements included foot stretcher force and the time required to reach peak force. The study was conducted as a case study on a single participant. Motion analysis was performed using video recordings and the Kinovea software, while statistical data processing was carried out using Microsoft Excel. A sequence of t-tests was used to determine differences between individual stroke periods. The results showed that fatigue affects rowing biomechanics, although the changes were not uniform across all observed parameters. Stroke length did not show a gradual decrease throughout the entire test, as a more pronounced shortening occurred mainly in the final part of the measurement. Statistically significant differences were found in handle position and temporal coordination of trunk movement relative to the leg drive; however, the changes did not occur in the predicted direction. The results also showed statistically significant changes in the angle between the head, shoulder, and hip, indicating the influence of fatigue on upper body position during rowing. Additional foot stretcher measurements showed a similar pattern of changes in both the left and right foot, while greater changes in time to peak force were observed mainly in the left foot. The findings suggest that fatigue primarily affects trunk and upper body movement and leads to adaptations in rowing stroke technique during prolonged effort. This master’s thesis provides additional insight into the relationship between fatigue and biomechanical changes in rowing stroke technique and represents a basis for further research in this field.
