Summary

Objective: To determine the effects of a stroboscopic training program on cognitive function in adolescent male volleyball players. The study aims to reveal the impact of using stroboscopic glasses during a portion of their training on volleyball players' cognitive functions. The data obtained from the study will be important for improving volleyball training programs and contributing to the sports science literature.

Detailed description

Numerous studies have shown that physical activity produces structural and functional changes in the brain that support cognitive functions. Some studies suggest that different types of exercise have different effects on cognition. A growing body of literature suggests that the effects of physical exercise on cognitive function may be related to the type of exercise. Sports are divided into two groups based on the predictability and consistency of the performance environment: open and closed skill sports. Open skill sports (e.g., volleyball, tennis, soccer, etc.) are externally paced activities performed in a dynamic, unpredictable environment, while closed skill sports (e.g., running, swimming, archery, etc.) are internally paced and performed in a static, predictable environment. A recent study showed that team athletes outperform recreational athletes in sustained attention and processing speed. Volleyball, as a team sport, may further enhance some aspects of cognitive skills. The purpose of this study was to examine the effects of volleyball training using stroboscopic glasses on cognitive function in adolescent male volleyball players. Effects of Stroboscopic Visual Training: Humans have a remarkable capacity for learning and adaptation. The disruption of visual information can force individuals to reduce their reliance on online visual feedback. It is believed that practicing in situations where visual input is poor will force individuals to better utilize the limited visual information available. This can train the perceptual and attentional abilities that support basic visuomotor control. Attention is a critical skill in many domains, and even a small increase can have profound effects; a small improvement in motion perception and focused attention is crucial for a competitive athlete or a soldier searching for an enemy combatant. Perceptual information influences many motor tasks and ensures the maintenance of accurate control in changing or uncertain environments. Consequently, changes in the environment will regularly produce variations in task performance.
