The relationship between reaction time and agility performance in young athletes: A study using perception–action technological devices

Aim. This study explored the correlation between the hexagon agility test (HAT) and two basic reaction time (RT) tests for visual stimuli that measure quick upper limb (RTs UL) and lower limb (RTs LL) movements. The effectiveness of these tests was assessed using a portable wireless measurement system (Fitlight Trainer™ Sports Corp, Canada). Materials and Methods. During a summer camp in southern Italy, 200 students participated, of whom 44 were chosen for inclusion in the study using a utility-based sampling approach. The students and their parents or legal guardians were informed about the experimental design and study procedures, and informed consent was obtained through signed forms. The study adhered to the Declaration of Helsinki and received approval from the Institutional Ethics Committee of Pegaso Telematic University (PROT/E 002466, 29/03/2024). Results. The observed correlations between RT and HAT support the hypothesis that RTs contribute to agility levels in young athletes. Despite the relatively small sample size, this study demonstrated that using perception–action devices such as Fitlight to measure RTs can effectively predict performance in field-based agility tests such as the HAT. The reliability and precision of these devices in assessing RTs are valuable for coaches, educators, and practitioners. In essence, these tools allow coaches and educators to monitor individuals' agility performance with greater accuracy, ensuring that observed improvements are attributed to the athletes' development rather than potential inconsistencies in the equipment. Conclusions. The results support incorporating targeted RT training into agility exercises, with the potential to enhance overall athletic performance.
