Abstract

Cilj istraživanja u ovom diplomskom radu bila je analiza vježbi „stražnji čučanj“ i „prednji čučanj“ u svrhu kreiranja najoptimalnijeg operatora za razvoj jakosti i snage u kondicijskoj pripremi veslača. Analizom specifičnosti veslačkog pokreta i veslanja kao sporta, predstavljene su prednosti pojedinog čučnja i njihov utjecaj na razvoj jakosti i snage u kondicijskoj pripremi veslača. Usporedba je prikazana kroz trenažne efekte koji se postižu stražnjim, odnosno prednjim čučnjem. Istraživanjem je obuhvaćen osvrt na sigurnost vježbi, aktivaciju mišićnih skupina za svaku varijantu, zahtjevnost metodike poučavanja te potencijalne opasnosti tijekom izvođenja.
Provedenom analizom može se zaključiti da u pogledu smanjenja rizika od ozljede koje su karakteristične i za samo veslanje, prednji čučanj zbog položaja utega zahtjeva značajno manji nagib prema naprijed u zglobu kuka, a s time i manja naprezanja u lumbalnom dijelu kralježnice uz maksimalnu amplitudu pokreta, odnosno u varijanti duboki čučanj. Nadalje, unatoč manjim opterećenjima koja se mogu podići u varijanti prednjeg čučnja, aktivacija ekstenzora je veća nego kod vježbe stražnji čučanj, a pri tome su kompresijske sile u patelo-femuralnom zglobu manje.
Sa vježbom čučanj želimo razviti mišiće koji daju najveći dio ukupne sile zaveslaja, a to je m. quadriceps femoris, a da pritom što manje riskiramo ozljedu drugih dijelova biomehaničkog lanca koji sudjeluju u pokretu što nam upravo omogućuje varijanta prednjeg čučnja.

Abstract (english)

The aim of the research was to analyse the exercises "back squat" and "front squat" in order to create the most optimal operator for the development of strength and power in the fitness training of rowers. By analysing the specifics of the rowing movement and rowing as a sport, the advantages of individual squats and their influence on the development of strength and power in the fitness preparation of rowers were presented. The comparison is shown through the training effects achieved by back and front squats. The research includes a review of the safety of the exercises, the activation of muscle groups for each variant, the demandingness of the teaching methodology and potential dangers during execution.
Based on this analysis, it can be concluded that in terms of reducing the risk of injury, which is also characteristic of rowing itself, the front squat, due to the position of the weights, requires a significantly smaller tilt forward in the hip joint, and thus less stress in the lumbar spine with maximum amplitude of movement, i.e. in the deep squat variant. Furthermore, despite the smaller loads that can be lifted in the front squat variant, the activation of the knee extensors is greater than in the back squat exercise, and the compression forces in the patellofemoral joint are smaller.
With the squat exercise, we want to develop the muscles that provide the largest part of the total force of the stroke, namely the quadriceps femoris muscle, while minimizing the risk of injury to other parts of the biomechanical chain that participate in the movement, which is exactly what the front squat variant allows us.
