Abstract
The aim of this study was to evaluate the effect of 9 weeks of the “FIFA 11+” warm-up program on vertical jump performance in soccer players. The study included 20 athletes of the Under-20 category from a Brazilian championship serie A team (age: 18.3±1.6 years; years of training: 8.2±1.3; body weight: 74.0±7.1 kg, height: 177.8±6.5 cm, and fat percentage: 10.7±1.9%), divided into an intervention group (G11+; n=10) and a control group (CG; n=10). The athletes were evaluated before and after the intervention regarding countermovement jump (CMJ) and squat jump (SJ) performed on a force platform. The maximum jump height was considered for data analysis. A mixed-model ANOVA was used to verify the main time vs. group effects. Both groups underwent the same training routine (physical, technical, and tactical) and only differed in terms of the proposed warm-up, which was performed three times per week in G11+. No significant difference in jump performance was observed in CG, while G11+ showed significant improvement in both types of jumps (CMJ: F=26.23, p<0.01; %change=11.3; SJ: F=23.16, p<0.01, %change=9.8). In conclusion, 9 weeks of intervention with the “FIFA 11+” warm-up program during routine training promoted significant improvement in jump performance.
