Introduction: Kinetics parameters are known as some of the main reasons of volleyball injuries resulting from landing during performing various skills. Information about lower extremity kinetics in landing will help to understand characteristics of various injuries and develop injury prevention programs. So the aim of the present study was kinetical analysis of predictive injuries parameters during landing in volleyball players. Materials and Methods: Eighteen junior male volleyball players were asked to perform three maximal block jump on a force platform. The data of force (Fmax, Fmin), impulse (I), loading rates (LRmax, LRmax-min), time to stabilization (TS), time to peak forces (TPF) and time to maximum to minimum force (TFmax-min) variables were extracted and analyzed Pearson product moment correlation coefficient (r) was employed to investigate possible relationship between kinetics and temporal landing parameters of block jump in participants. Results: The results showed significant correlations between some variables including Fmax with LRmax, LRmax-min and TPF, Fmin with TS, LRmax with Fmax, LRmax-min and TPF, LRmax-min with Fmax, MLR, TPF and TFmax-min, TS with Fmin, TPF with Fmax, LRmax, and LRmax-min, TFmax-min with LRmax-min during landing in volleyball players. Conclusion: Biomechanists and sports injury expertise should monitor both of temporal and kinetic variables with respect to performance optimization as well as decreasing injury prevalence.
