Abstract

Glavni cilj ovog diplomskog rada je istražiti utjecaj cheating metode na maksimalni broj ponavljanja u vježbi pregib podlaktica EZ šipkom stojeći. Uzorak ispitanika činila je zdrava, tjelesno aktivna muška populacija (n = 8). Testiranje se provodilo u dva odvojena mjerenja, izvedba vježbe pregiba podlaktica u kontroliranim uvjetima i izvedba iste vježbe u uvjetima dozvoljenog varanja. T-testom za zavisne uzorke je utvrđeno postojanje statistički značajne razlike u broju ponavljanja između uvjeta (t = -8,23; p < 0,001). Veličina učinka (Cohenov d) izračunata je za promjene između prvog i drugog mjerenja te je utvrđena velika veličina učinka (d = 8,7). Veličinom porasta izraženo je ukupno povećanje broja ponavljanja koje iznosi 128,89%. Rezultati indiciraju na to da je cheating metodom moguće produljiti trajanje jedne serije, čime se ostvaruje veći volumen rada, koji je potencijalno značajan za veći hipertrofijski učinak. Produljenim trajanjem rada prouzrokujemo veću mehaničku napetost, koja je umnožak intenziteta (veličina opterećenja) i vremena pod napetosti, što rezultira većom aktivacijom motoričkih jedinica, a time i većim hipertrofijskim odgovorom. Korištenje cheating metode umjerenim intenzitetom i izvedbom u zoni sigurnosti može poslužiti kao alat kojim je moguće utjecati na razvoj mišićne hipertrofije.

Abstract (english)

This paper aimed at investigating the effect of the cheating method on the maximum number of repetitions in the EZ barbell forearm curl standing exercise. The sample consisted of a healthy, physically active male population (n = 8). Testing was performed in two separate measurements, performing the forearm curl exercise under controlled conditions and performing the same exercise under allowed cheating conditions. T-test for dependent samples has revealed that there is a statistically significant difference in the number of repetitions between conditions (t = -8.23; p < 0,001). The effect size (Cohen's d) was calculated for the changes between the first and the second measurement and a significant change size has been determined (d = 8.7). The size of increase expressed a total increase in the number of repetitions, which amounted to 128.89%. The results indicate that the cheating method can extend the duration of one series thus achieving a higher volume of work, which is significant for a higher hypertrophic effect. Prolonged work causes greater mechanical tension, which is the product of intensity (load value) and time spent under tension, which results in greater activation of motor units, and thus a greater hypertrophic response. The use of the cheating method with moderate intensity and performance in the safety zone can serve as a tool by which we will influence the development of hypertrophy.
