Abstract

Sok od višnje i njegovi učinci na oporavak mišića postaju sve češća tema u znanstvenim istraživanjima tjelesne aktivnosti. Sadrži fitokemikalije koje djeluju antiupalno i visoku koncentraciju melatonina koji poboljšava kvalitetu sna. Cilj ovog istraživanja bio je utvrditi može li sok od višnje povoljno utjecati na san nogometaša (n=15, dobi 17-31 godina) i smanjiti subjektivan osjećaj opterećenja treninga. Nogometaši su tijekom kontrolnog tjedna ispunjavali upitnik o spavanju te evidentirali subjektivni osjećaj opterećenja (Borgova skala). Zatim su tijekom tri tjedna konzumirali sok od višnje, sok od jabuke ili čokoladno mlijeko (200 mL/dan 1-2 h prije spavanja). Pozitivan utjecaj soka od višnje na kvalitetu spavanja vidljiv je kod pojedinih ispitanika u usporedbi s ostala dva napitka i kontrolnim tjednom. Kod subjektivnog osjećaja opterećenja treninga, rezultati su nedosljedni. Na temelju literaturnih podataka opisanih u ovom radu sportašima se može sok od višnje (230-340 mL) preporučiti za ubrzanje oporavka, također i za poboljšanje kvalitete sna.

Abstract (english)

Tart cherry juice and it's role in muscle recovery is increasingly studied topic in sports medicine. It is rich with phytochemicals with anti-inflammatory effects. Additionally having high concentration of melatonin, it can be effective sleep remedy. The aim of this study was to establish whether tart cherry juice can have positive influence on sleep among football players (n=15, age 17-31 years) and reduce perception of exertion. The questionnaire about sleep and Borg scale were administered to subjects during weekdays of 1 week. During the following 3 weeks subjects consumed tart cherry juice, apple juice or chocolate milk (200 mL daily, 1-2 hours before sleep). Positive influence of tart cherry juice on sleep quality is evident among some subjects compared to other two drinks and baseline week. Results for rated perceived exertion are inconsistent. Based on previously published data described in this thesis, tart cherry juice can be recommended to athletes (230-340 mL) for fast recovery and sleep quality improvement.
