Effect FIFA 11+ level three on speed and agility among soccer athletes under 15

This study employs a quasi-experimental pre-post design to investigate the impact of the FIFA 11+ Level Three injury prevention program on the sprint speed and agility of 16 male youth soccer players (aged 12–15). By comparing an experimental group using the Level Three protocol against a control group performing traditional warm-ups, the research utilizes the 20-Meter Sprint Test and Illinois Agility Test to evaluate performance changes. The study addresses a critical developmental gap in sports science literature, aiming to determine if this advanced injury prevention framework doubles as an effective performance enhancement tool for adolescent athletes.
