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.

• Kinetics analysis of a specific volleyball skill.
• Demonstrating the importance of Biomechanics in the professional volleyball game.
• Separating the various phases of performance regarding biomechanics of block jump.
Plain Language Summary
The main goals of biomechanics are human performance optimization as well as injury prevention. The important keynote is to find the glorious skills in each sport, and in volleyball, the block jump is known as a key factor of success. Combining and merging biomechanical principles in volleyball block jump will result in a better understanding of the nature of skills performance. Seventeen junior volleyball players attended the recent investigation and performed block jumps on the force platform. Kinetic data were collected and different phases of jumping were also derived according to the force-time data. No significant differences were found between the side blockers and middle blockers in volleyball when it comes to the kinetics of jumping and landing. This means that both positions exhibit similar patterns and mechanics in terms of their jumping and landing movements
