AB The aim of this study was to investigate the relationships between repeated explosive effort sequences (20+20¿m shuttle sprint with change of direction, kicking and jumping), metabolic response (lactate and ammonia), and fitness qualities (strength and endurance) in under-19 soccer players. 21 players completed: 1) sprint test: 30¿m (T30) and 40¿m (20+20¿m) shuttle sprints; 2) countermovement jumps (CMJ); 3) maximal kicking; and 4) 9 repeated-explosive effort sequences (RES); 4) a progressive isoinertial loading test in full squat to determine the load which subjects achieved ~1¿m¿·¿s¿1 (V1-load); 6) Yo-Yo Intermittent Recovery Test Level 1 (YYIRT-1). Mean sprint time of the 9 repeated sprints (RSAmean1¿9) showed correlation with V1-load (r=¿¿0.52 [¿¿0.79, ¿¿0.25]) metabolic response (lactate, r=0.67 [0.47, 0.87] and ammonia, r=0.53 [0.27, 0.79]). YYIRT-1 correlated with RSAmean1-9 (rw=¿¿0.78 [¿¿0.92, ¿¿0.64]) when the body weight was controlled. Furthermore, the 3 first sprints (RSAmean1-3) correlated with RSAbest (r=0.93 [0.88, 0.98]), V1-load (r=¿¿0.64 [¿0.86, ¿¿0.42]), and T30 (r=0.63 [0.41, 0.85]). These results suggest that the soccer player¿s lower body strength (V1-load, jumping and sprinting) explains a large part of the performance in the first sequences, whereas the aerobic capacity, estimated through YYIRT-1, becomes more important to performance as the number of sprints is increases.
