Sažetak

U sadašnje vreme potrošnja dodataka i energetskih napitaka je veoma česta kod sportista. Međutim, postoje ograničena istraživanja u afirmisanju potrebe za konzumiranjem energetskih napitaka, pre iza vreme kratkog trajanja intenzivnih vežbanja. Takođe nema podataka o kvalitativnom rangiranju ovih produkata koji služe za odlaganje nastupa zamora i akumulacije laktata. Cilj ovog istraživanja je bio da ispita akutne efekte dva energetska pića (ORGAZMA and MegaBasic) na anaerobnu snagu i nivoe laktata kod sportista. Trideset dobro treniranih sportista studenata (starost: 22.34±1.74 godina, visina: 181.26±7.66 cm, težina: 76.37±6.85 kg i BF%: 13.2±2.7%) volontirali su i bili slučajno odabrani da učestvuju u ovom istraživanju. Ovo istraživanje je bilo podeljeno na dve odvojene sesije, sa 4 dana odmora između istih. U prvoj sesiji, svi subjekti učestvovali su u RAST testu, posle standardnog doručka i njihovi nivoi laktata su mereni uzimanjem uzoraka krvi iz srednjeg prsta sa preporučenim laktomerom u tri faze {(1) pre početka testa, 2 i 3) dva i šest minuta posle odmora kada je test završen}. U drugoj sesiji, ispitanici su bili slučajno podeljeni u tri grupe (Placebo, OR and MegaBasic). Onda je svaka grupa primila 6 ml/kg.bw navedenih napitaka (četrdeset minuta pre testa RAST) odmah posle uzetog doručka. Nakon toga, ispitanici su testirani RAST testom drugi put. Naši rezultati pokazuju da u grupi OR, minimum i prosečna moć su bile povećane respektivno 11.01% i 9.15%, a nivo laktata koji je bio meren dva minuta posle RAST testa, bio je smanjen 3.63% (p<0.05). Može se zaključiti da se ORGAZMA može smatrati ergogenetskim agensom, ali izgleda da je verovatno ergogenetski kapacitet ovog energetskog pića limitiran i kratkotrajan u slučaju stalne upotrebe.
