Purpose:The aim of this study was to investigate flexibility, strenght, endurance, speed, balance of upper extremity and quality of life among adolescent volleyball players and sedentary.Methods: 20 adolescent volleyball players and 20 adolescent sedentary totally 40 participants, who were aged between 12-18 years, were included in the study. Back Scratch Test, Hand Claw Force Test, Modified Pushup Test, Medicine Ball Throwing, Bent Arm Hang Test, Plate Tapping Test, Upper Extremity Y Balance Test, WHOQOL-BREF were used to evaluate flexibility, strenght, endurance, speed, balance of upper extremity and quality of life. 'İndependent sample t-test' was used for statistical analysis.Results: Statistically significant changes were detected in datas obtained as a result of Modified Push-up Test, Medicine Ball Throwing, Bent Arm Hang Test, Plate Tapping Test and Upper Extremity Y Balance Test evaluations (p<0,05). It was determined that the upper extremity strength, endurance, speed and balance parameters of the adolescent volleyball player group were better than the adolescent sedentary group (p<0,05).
Conclusion:As a result of the study, it was seen that playing volleyball in adolescence contributes positively to upper extremity strength, endurance, speed and balance. İndividuals in this period directing to sports may affect the physical, psychological and social development of the individual and their future sports performance.
