Purpose: The successful performance of block skills is crucial for volleyball players, requiring efficient techniques that optimize time, movement, and vertical jump. The purpose of the present investigation was to compare the kinetic temporal phasic differences between middle and side blockers among elite volleyball players during block jump. 
Methods: Seventeen junior male volleyball players, consisting of eight middle blockers and nine side blockers, participated in this research. The evaluated skill was the block jump ability. Data collection involved calibrating a force plate (Kistler® 1000 Hz). An independent t-test was used to compare mean values between the two groups during jumping (p<0.05). 
Results: The results indicated no significant differences between middle and side blockers in terms of time and force during the amortization phase. 
Conclusion: These findings provide valuable insights into monitoring time and force variables among middle and lateral blockers. Trainers can utilize these results to tailor task-specific training programs that optimize performance outcomes.
