摘要：Aim: The study aims to conduct a kinematical analysis of blocking skill in volleyball and their relationships with the explosive force of lower limbs,for the athletes from the elite Algerian team. Methods: A total of 06 male Volleyball Players from the elite Algerian team as volunteers (Age: 25.66+3.32 yr,Length:198.00+3.68 cm,Weight: 86.66+6.62 kg). We used for kinematical analysis the software Dartfish9. For video capturing,we used three cameras (AEE Magic Cam) for record the performance during an Experimental competition,two CAMІ&П(X1m,Y,Z1.5m) were placed in the sides of volleyball Court,and CAMⅢ(X4.5m,Y1m,Z1.5m) behind the elite Algerian team. Also,two force Explosive tests were executed;Squat Jump (SJ) and Counter Movement Jump (CMJ). The data were analyzed in SPSS 22.0 program. Descriptive statistics (mean±SD) and P test for the correlations between variables studied. Results: Through the statistical analysis,there were significant correlations between values of CMJ test with both of the DHeightBCG (p<0.01),& DMax height (p<0.01),and between variable DMax height with each of the ° Trunk (p<0.01),& ° Knee (p<0.01),and DLowBCG (p<0.01),and DHeightBCG (p<0.01) respectively,at the 0.05 level. Also,between DLowBCG with ° Trunk (p<0.01),and with ° Knee (p<0.01). Conclusion: This study was able to produce results that are helpful to coaches when deciding when they are considering vertical jump heights during the performance of blocking skill in volleyball,through: developing the technical aspect of the blocking skill by training players to improve the kinematical properties of a certain degree;especially,the angles of the lower limbs of the body,such as the angles of the trunk,knee,and ankle.
