Effects of Physical and Cognitive Fatigue on Reaction Time and Depth Perception in Adolescents

This study investigates how physical fatigue, cognitive fatigue, and a combination of both affect reaction time and depth perception in adolescents. Sixty healthy adolescents will participate in four experimental conditions: a control condition, a physical fatigue condition, a cognitive fatigue condition, and a combined fatigue condition. Physical fatigue will be induced using a modified shuttle run protocol, while cognitive fatigue will be induced using computerized Stroop and mental arithmetic tasks. Reaction time will be assessed using the BlazePod system, and depth perception will be evaluated using the Titmus Fly Stereotest before and after each condition. Heart rate, perceived exertion, and mental fatigue will also be measured to verify the effectiveness of the fatigue protocols. The findings may improve understanding of how different types of fatigue influence perceptual and motor performance in adolescents and may contribute to the development of safer and more effective training and sport participation strategies.
