Flicker glasses give volleyball players a balance boost

This study tested whether wearing stroboscopic glasses (glasses that flicker between clear and dark) during training could improve balance and body awareness in 30 teenage male volleyball players. Half the players wore the glasses for 2.5 minutes per session over six weeks, while the other half trained normally. Results showed that both groups improved balance, but the stroboscopic group had better gains in body awareness (knowing where your limbs are without looking). The study suggests these glasses might be a useful training tool for athletes.
