Investigation of the Effects of Exercises Performed With Stroboscopic Glasses on Athletic Performance in Volleyball Players

The aim of this study was to examine the effects of exercises performed with stroboscopic glasses on athletic performance in volleyball players. 40 professional male volleyball players aged between 18-35, who had not undergone any surgery in the last 6 months and who had no chronic systemic disease were included in the study. 20 individuals were randomly assigned to the stroboscopic glasses group and 20 individuals to the control group. Individuals in the stroboscopic glasses group were informed about stroboscopic glasses. Individuals in the stroboscopic glasses group wore glasses and individuals in the control group did their exercises without glasses for 6 weeks. Individuals' visual reaction time, auditory reaction time and target-oriented reaction time were measured with the Human Benchmark test, agility assessment with the T Agility test, anaerobic capacity assessment with the vertical jump test, balance assessment with the Flamingo Balance test and coordination assessment with the Hexagonal Coordination test. The evaluations were made three times, before exercise, 6 weeks after exercise and 10 weeks after exercise.

About this study

Individuals' visual reaction time, auditory reaction time and target-oriented reaction time were measured with the Human Benchmark test, agility assessment with the T Agility test, anaerobic capacity assessment with the vertical jump test, balance assessment with the Flamingo Balance test and coordination assessment with the Hexagonal Coordination test. The evaluations were made three times, before exercise, 6 weeks after exercise and 10 weeks after exercise.

Treatment and study plan

stroboscopic visual training

Device

40 volleyball players were evaluated at three times: pre-exercise, after 6 weeks and after 10 weeks regard to reaction time, agility, anaerobic performance, balance and coordination. Experimental group used stroboscopic glasses when doing exercise. Exercise program consisted lunge, jumping and balance exercises. Each exercise consisted 12 repetitions and 3 sets. Stroboscopic glasses were adjusted to 100 ms on/150 ms off flash level 3. This frequency is always preferred scientific research about stroboscopic visual training.
