Abstract :The aim of this study was to investigate the effects of rosehip juice supplement on different performance components of team athletes (n=66) aged 14-18 years who participated in sports activities 3 days a week. A 4-week pretest-posttest control group experimental model was used and Queen’s College Step Test, Running-based Anaerobic Sprint Test, Hexagonal Obstacle Test, 505 Agility Test, Shuttle Run Test and 35 Metre Sprint Test were administered as pre-tests. Research group consumed 250 ml of rosehip juice 5 days a week for 4 weeks. After 4 weeks, the same tests were administered to all participants. SPSS 25.0 analysis program was used to evaluate data. The difference between pre-test and post-test effect sizes between the two groups was 7% for Hexagonal Obstacle Test and 22% for 505 Agility Test. VO2max value calculated from the Queen’s College Step Test data, findings of Shuttle Run Test and 35 m Sprint Test administered for speed performance were not in favour of the research group. Running-based Anaerobic Sprint Test (RAST) was administered to evaluate anaerobic capacity and fatigue index. The data obtained showed that maximum anaerobic power increased by 20%, minimum anaerobic power increased by 22% and mean anaerobic power increased by 31%. The difference of the research group in fatigue index data was 34%. As a conclusion, the effects of rosehip juice supplement on agility performance (7%, 22%), maximum anaerobic power capacity (20%), minimum anaerobic power capacity (22%), mean anaerobic power capacity (31%) and fatigue index (34%) were positive and comprehensive.
