Purpose: It is essential to analyze demographic characteristics to enhance the performance of the block jump skill based on the kinetics domain. For this reason, this study aims to analyze the relationship between jump height and the demographic characteristics of young volleyball players while performing block jumps based on kinetics.
Methods: This study included twenty-one young male volleyball players. Each player was instructed to perform 3 block jumps on a force plate using maximum power, and their jump height was estimated using a kinetics method. Moreover, the players’ demographic features, such as height and weight were also measured for the analysis. To determine the relationship between the players’ jump height and demographic characteristics,  a one-way linear regression statistical method was used.
Results: No significant relationship was found between height and weight (demographic characteristics) and jump height. However, height had a higher factor loading with jump height, indicating more correlation with jump height than weight (P≤0.05).
Conclusion: To enhance the jumping and landing abilities of elite volleyball players, it is suggested that coaches, players, and specialists assess biomechanical performance through various means. Demographic characteristics can serve as useful indicators to improve performance. A thorough analysis of these indicators can significantly aid in achieving success in volleyball.
