Abstract

Cilj istraživanja bio je utvrditi unos proteina, njihovu kvalitetu i vrijeme unosa kod CrossFit natjecatelja. U ispitivanju je sudjelovalo 6 natjecatelja prosječne dobi 33 godine koji se bave CrossFit-om dulje od 6 mjeseci te su proveli jednodnevni dnevnik prehrane uz vaganje na dan kada su i trenirali. Preporučeni unos proteina za CrossFit se ekstrapolira iz preporuka za sportove snage i jakosti i iznosi 1,2-2,0 g/kg, a među ispitanicima je uočen raspon unosa od 1,35 do 2,5 g/kg. Ispitanici pretežno konzumiraju proteine životinjskog podrijetla koji čine 55-95% ukupnog dnevnog unosa proteina. Unos proteina manji je u jutarnjim satima (15% ukupnog unosa), a veći u popodnevnim satima, osobito za ručak (35,5%), što se slaže i s dnevnim rasporedom treninga koji se pretežno odvijaju navečer. Od ukupno 6 ispitanika, njih 5 konzumira namirnice dodatno obogaćene proteinima (proteinske čokoladice, proteinsko mlijeko) ili proteinske suplemente (proteine sirutke) i njihov unos iznosi 10-30% ukupnog proteinskog unosa. Hrana ili dodaci prehrani bogati proteinima konzumirani su 1 h prije ili unutar 1 h nakon treninga CrossFit-a.

Abstract (english)

The purpose of the presented study was to determinate protein intake, quality of those proteins and time frame in which they were taken. Six who participated (aged 33 years) have been training CrossFit for more than 6 months. To determinate protein intake, athletes conducted one-day food diary and have weighted their food on training days. Protein intake recommendations for CrossFit are non-existing, so we use general recommendations for strenght sports which are 1,2-2,0 g/kg. Intake in our athletes varies from 1.35 to 2.5 g/kg body mass. Animal based proteins are more consumed than plant based proteins, and they make 55-95% of daily protein intake. Protein intake is lower in mornings (15% of daily intake) and bigger in the afternoon, especially for lunch (35,5%), which collides with the fact that training is mostly in the evening. Five out of six athletes consume food with added proteins (protein bars, milk with added protein) or protein supplements (whey) and they make 10-30% of daily protein intake. Food rich with protein is usually consumed 1 hour before or within 1 hour after CrossFit workout.
