Associations between vertical and horizontal jumps with power values during deadlift exercise among youth soccer (football) players

Objectives: The similarity in joint angles and performance between the deadlift and vertical jumps was previously displayed. Additionally, the hexagonal barbell produces greater peak power compared to performance with traditional Olympic barbell. To optimally develop power and performance in explosive tasks in sport (such as jumps), training with the load that maximizes the power output is considered ideal. Therefore, the objective of this research is to investigate the relationship between jumps and power values during the deadlift exercise performed with a hexagonal barbell. Methods: 14 youth soccer players (16-18 years old) were tested on the Sargent jump test, broad jump test, one repetition maximum (1RM) using the PUSH 2.0 band that was used for displaying the power values at 45, 55, 65, 75, 85, and 95% of 1RM. Correlations between jumps and power values at different percentages of 1RM were evaluated by Pearson’s correlation coefficients. Results: The significant correlation (p<0.05) was evidenced between Sargent jump test and power value at 45, 55, 65, 75% 1RM (r= 0.75 ; r=0.60 ; r=0.56 ; r=0.53, respectively), and between Broad jump and power at 45, 55, 65% 1RM (r=0.71 ; r=0.51 ; r=0.54, respectively). Conclusion: Power values at moderate loads were significantly correlated with vertical and horizontal jumps. Therefore, it could be expected that training at moderate loads that produce the greatest power values will lead to greater development of jumping performance, which can be important also for improving soccer performance.
