This study was conducted to investigate the effects of training with stroboscopic glasses on athletic performance in volleyball players. 54 male volleyball players participated in the study. Individuals were randomly divided into two groups as experimental group (n=27) and control group (n=27). 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.

In the study, individuals were evaluated face to face at the Turkish Volleyball Federation Beştepe Volleyball Hall. The evaluations lasted 30 minutes for each individual. After the sociodemographic information of the individuals in our study was recorded, individuals were divided into two groups as the experimental group and the control group using a computer numbering system. Necessary information and explanations were provided to individuals in the experimental group with Senaptec brand stroboscopic glasses (Beaverton, Oregon USA) before the application. Passing, reception and blocking training was performed with glasses in the stroboscopic glasses group. Training was performed without stroboscopic glasses in the control group. It was performed after the players' warm-up exercises for 3 sessions per week for 6 weeks. Since there was one stroboscopic glass, the evaluations were planned for 2 days, lasting 30 minutes for each individual. Reaction time, agility and anaerobic power were performed on the first day, and coordination and balance were performed on the second day. The evaluations were performed after the warm-up exercises. The evaluations were performed twice, before the training program and at the end of 6 weeks.
