The objective of this research was to determine the relationship between countermovement jumping and speed tests (10-30 m) and agility. The sample consisted of 169 young soccer players between the under-13 and under-19 categories, to whom the counter-movement jump test, speed (10-30 m) and zigzag agility were applied. The results show that the height of the countermovement jump shows a high negative correlation with speed 10 m (r = -. 693), 30 m (r = -. 731) and agility (r = -. 490). Similarly, the results of the countermovement jump power are negatively correlated with speed 10 m (r = -. 658), 30 m (r = -. 719) and agility (r = -. 484). The highest coefficients of determination corresponded to the height of the countermovement jump and speed (r2 =.534) and the power of the countermovement jump and speed (r2 =.517). The results obtained in the present study suggest that the countermovement jump has a high degree of influence on speed performance (10-30 m), which seems to be not so clear in the agility variable.
