Background: Physical training in soccer requires the development of different physical capacities, including strength and speed. These capacities are considered of great importance
for the achievement of specific actions of the game at high intensity. The aim of this study was to analyze the association between the performances of young soccer players in the sprint test of 20 m
with the vertical jump test with countermovement (CMJ).
Methods: 21 male soccer players participated in this study. , The athletes presented an average age of 17.38 (SD ± 1.53), height 1.74 m (SD ± 0.062) and weight 66.98 kg (SD ± 6.66).
To assess the speed at 20 meters, two photocells were used (CEFISE®, São Paulo) connected to a computer provided with the software Speed Test 6.0. Regarding strength, CMJ test protocol was conducted
in the contact platform (CEFISE ®, São Paulo), connected to a computer with the Jump System 1.0 software. Pearson's correlation coefficientwas used to analyze the linear association between the
Results: The average performance in the sprint of 20m was 3.01 ± 0.16 s. For vertical jump the average was 37.72 ± 3.67cm. The correlation between the two variables presented the
coefficient of r = - 0.530 (p=0,0142), showing a moderate and significant correlation.
Conclusions: These results suggest that the increase of powerlevels will also increase the 20m sprint speed, and with this, power exercises are important to improve the speed of
athletes in soccer players.
