Abstract

Powerlifting je sport relativne i apsolutne jakosti u kojem natjecatelji kroz svoj godišnji ciklus izmjenjuju različite periode priprema, a isti bi trebali biti popraćeni adekvatnom sportskom prehranom. U ovom radu napravljena je inicijalna procjena powerliftera (5 muškaraca i 5 žena u dobi od 19 do 35 godina, raspona indeksa tjelesne mase od 20,20 do 32,11 kgmˉ²) koja je uključivala dijetetičku metodu dnevnika prehrane uz vaganje s vođenjem dnevnika tjelesne aktivnosti. Prikupljenim podacima dobiven je uvid u energetsku ravnotežu i unos nutrijenata (proteina, ugljikohidrata, masti, željeza, kalcija i vitamina C), dok je sveukupna kvaliteta prehrane procijenjena pomoću internacionalnog indeksa kvalitete prehrane (DQI-I). Znanje o sportskoj prehrani ispitanika procijenjeno je modificiranim prethodno razvijenim upitnikom za ovakve svrhe, a na temelju svih prikupljenih podataka provedena je individualna edukacija ispitanika što je rezultiralo poboljšanjem kvalitete prehrane tj. povećanjem broja bodova DQI-I-a u prosjeku s 55,26 ± 7,07 na 59,88 ± 9,17.

Abstract (english)

Powerlifting is a sport of relative and absolute strength in which competitors alternate different periods of preparation throughout their annual cycle, which should be accompanied by adequate sports nutrition. In this thesis, an initial assessment of powerlifters (5 men and 5 women aged 19 to 35 years old with a body mass index range of 20,20 to 32,11 kgmˉ²) was made, which included a dietary method of weighed food diary accompanied with a physical activity diary. The collected data provided insight into energy balance and nutrient intake (protein, carbohydrates, fats, iron, calcium and vitamin C), while the overall quality of nutrition was assessed using the Diet Quality Index - International (DQI-I). Knowledge of sports nutrition of respondents was assessed by a modified previously developed questionnaire for such purposes, and based on all collected data, individual education of respondents was conducted. Education resulted with the improvement of their diet quality, by the increase of the average number of DQI-I points from 55.26 ± 7, 07 to 59.88 ± 9.17.
