The aim of this study was to investigate the difference between a Low Load High Velocity (LLHV) and a High Load Low Velocity (HLLV) eight week in-season strength training program on strength and jump performance in elite youth soccer players. In this study 25 elite youth soccer players from an U-17 and an U-19 team participated and both teams were separated into an LLHV-group and a HLLV-group (for U-17 LLHV n = 6, HLLV = 8, for U-19 LLHV n = 5, HLLV n = 6). The outcome measures included tests for the assessment of maximal strength (One Repetition Maximum (1RM)) and vertical jumping height (Squat Jump, Counter Movement Jump, Counter Movement Jump free and Drop Jump). Based on the 1RM performance in the pre-test individual training programs were composed. The eight week intervention consisted of a weekly strength training session and regular soccer training. The LLHV-group performed their exercises at 35% 1RM with a high velocity and the HLLV-group at 70% 1RM with a low velocity. Data was analyzed with paired sample t-tests (p=0.05), repeated measures ANOVA and magnitude-based inferences. Results revealed no significant differences between LLHV and HLLV. Furthermore, results showed an improvement of strength in almost all players (varying from 6.97% to 25.94%), but jump performance barely improved (varying from -2.82 % to 8.67%). In general the results showed no significant difference in improvements between LLHV and HLLV, as both groups improved in strength and neither had consistent improvements in jumping performance.
