Abstract. The purpose of this study was to determine the relationship between the maximum number of repetitions and selected percentages of one repetition maximum which could be performed by trained and untrained males, especially using free weights. Nine trained (T) and 9 untrained (UT) males participated in this study. The subjects performed one set to failure at 75, 85, and 95% of 1RM in the back squat, bench press, and arm curl, which were randomized, balanced, and matched. Data were analyzed using two-way analysis of variance. There were significant differences (p < 0.05) between T and UT at 85 and 95% of 1RM in the arm curl. At 75 and 85% of 1RM, T and UT performed more repetitions (p < 0.05) during the back squat than the bench press or arm curl. Both groups performed significantly (p < 0.05) more repetitions during 75% of 1RM than 85 and 95% of 1RM (75 > 85 > 95%). The rating of perceived exertion (RPE) was greater (p < 0.05) for high intensity than moderate intensity. In conclusion, the number of repetitions is dependent on the amount of muscle mass and exercise intensity, while the training status of the subjects has a minimal impact. When percentage of 1RM increases, the RPE increases as well.
Key words: intensity, weight training, free weight, rating of perceived exertion
ODNOS IZMEĐU IZABRANIH PROCENATA PONAVALJANJA PRI UPOTREBI MAKSIMALNE SNAGE I BROJA PONAVLJANJA IZMEĐU ISTRENIRANIH I NETRENIRANIH MLADIĆA
Cilj ovog istraživanja bio je da se odredi odnos između maksimalnog broja ponavljanja i odabranih procenata ponavljanja pri upotrebi maksimalne snage istreniranih i netreniranih mladića, uz upotrebu tegova. Devet treniranih (T) i devet netreniranih (UT) mladića učestvovalo je u istraživanju. Ispitanici su radili po jedan set vežbi do greške pri 75, 85, i 95% maksimalne snage (zadnji čučanj, pretklon, i savijanje ruku) dok su sve vežbe nasumice bile izbalansirane i povezane. Svi podaci su analizirani upotrebom analize varijanse. Značajne razlike se mogu utvrditi između (p < 0,05) T i UT grupe pri 85 i 95% ponavljanja pri upotrebi maksimalne snage u vežbi savijanja ruku. Pri upotrebi 75 i 85% maksimalne snage, T i UT grupe su imale veći broj ponavljanja (p < 0,05) pri izvođenju zadnjeg čučnja nego pri pretklonu ili savijanju ruku. Obe grupe su imale značajno veći broj ponavljanja (p < 0.05) pri upotrebi 75% maksimalne snage nego pri upotrebi 85 i 95% maksimalne snage (75 > 85 > 95%). Stopa utvrđenog zamora (RPE) bila je veća (p < 0,05) kod vežbi sa većim nego srednjim intenzitetom. Kao zaključak možemo navesti da broj ponavljanja zavisi od količine mišićne mase i intenziteta vežbi, dok je istreniranost učesnika imala minimalni uticaj. Kada se stepen maksimalne snage poveća, poveća se i stopa zamora.
