Passing, reception and blocking exercises were performed paired with stroboscopic glasses in the experimental group and without glasses in the control group for 6 weeks. Measurements were made twice, before the exercise program and at the end of the 6-week exercise program. Reaction time was evaluated with the Human Benchmark test, agility with T agility test, anaerobic power with vertical jump, balance with Flamingo balance test, coordination with Hexagonal coordination test.', 'detailedDescription': "In the study, individuals were evaluated face to face at the Turkish Volleyball Federation Beştepe Volleyball Hall.
