DEVELOPMENT OF ACCELERATION SPEED IN U15 FEMALE VOLLEYBALL PLAYERS THROUGH A SPECIFIC TRAINING PROGRAM

Aim. The aim of this study was to evaluate the effects of a volleyball-specific physical training program on acceleration speed and visual-motor coordination in U15 volleyball players. Methods. Twenty-two athletes from CTF Mihai I Bucharest were evaluated at two experimental moments (initial and final) using the Witty RED electronic system, which allows the measurement of acceleration speed and motor response accuracy to visual stimuli. In the interval between tests, a specific physical training program was implemented, focused on developing these qualities. Results. Statistically significant differences were recorded between the two tests for both total time (t(21) = 5.99, p .001, d = 1.28) and response variability (Gap) (t(21) = 29.83, p .001, d = 6.36), highlighting improvements in acceleration speed and visual-motor coordination. Conclusions. A well-structured specific physical training program can contribute to optimizing movement speed and increasing the consistency of motor response in youth volleyball.
