Effects of FIFA 11+ level 2 warm-up on physical performance among U-15 soccer players

This true experimental study investigates the acute performance-enhancing effects of the FIFA 11+ Level 2 program compared to traditional warm-ups among 22 male U-15 soccer players from PLD Seremban. Utilizing a single-session pre- and post-test design, the research measures changes in agility, core strength, and muscular power through the Illinois Agility Test, 7-Level Sit-Up test, and Vertical Jump. By addressing the gap in youth-specific research, the study aims to determine if this injury prevention variant serves as an effective evidence-based strategy for immediate athletic improvement in adolescent athletes.
