This randomized clinical trial investigates the comparative effects of the FIFA 11+ and RAMP (Raise, Activate, Mobilize, Potentiate) warm-up protocols on the agility and sprint performance of young soccer players. The study involves 34 male players aged 8 to 15, who will be randomly assigned to one of the two warm-up groups for a six-week intervention period. Key performance outcomes-agility, measured by the Illinois Agility Test, and sprint speed, measured by a 30-meter sprint test-will be assessed both before and after the intervention. The research aims to address a gap in sports science by directly comparing these two popular protocols in a youth population, with the goal of providing coaches with clear, evidence-based recommendations for optimizing athlete development and reducing injury risk. Data will be analyzed through SPSS version 27.00.

Parallel
FIFA 11+ Warm-Up Program
Other interventionThe intervention for the first group is the FIFA 11+ warm-up protocol, a standardized 20-minute program developed by FIFA for injury prevention and performance enhancement. It consists of 15 exercises performed in a specific sequence at the start of each training session, divided into three parts: the first part (8 minutes) involves slow-speed running combined with active stretching and partner contacts to practice cutting, deceleration, and proper landing; the second part (10 minutes) focuses on strength, plyometrics, and balance exercises, including core stability, eccentric hamstring strengthening, and proprioceptive training, with three progressive difficulty levels; and the third part (2 minutes) consists of high-intensity running drills with planting and cutting movements to prepare for game-speed activities.
RAMP Warm-Up Program
Other interventionThe intervention for the second group is the RAMP (Raise, Activate, Mobilize, Potentiate) protocol, a systematic, four-phase warm-up designed to progressively prepare athletes for high-intensity performance. The first phase, Raise (5 minutes), uses light cardiovascular activities like jogging and skipping to elevate body temperature and heart rate. The second phase, Activate (5 minutes), involves dynamic mobility exercises such as leg swings, lunges, and bodyweight squats to activate key muscle groups. The third phase, Mobilize (5 minutes), focuses on enhancing joint range of motion and movement patterns through dynamic stretches and sport-specific drills. The final phase, Potentiate (5 minutes), includes high-intensity, explosive activities like sprint accelerations, box jumps, and change-of-direction drills to activate the nervous system and optimize neuromuscular readiness for peak performance.
Illinois Agility Test (IAT)
The Illinois Agility Test is a field-based assessment designed to measure an athlete's ability to accelerate, decelerate, and change direction rapidly. The test involves sprinting and weaving through a set course marked by cones. The total time to complete the course is recorded using a stopwatch. The IAT is a highly valid and reliable tool for assessing agility. Recent studies report high content validity (Aiken's V = 0.93) and strong reliability (r = 0.81), confirming its effectiveness for evaluating agility in athletes. Additional research has shown the IAT to have excellent interrater reliability and moderate to good test-retest reliability, making it suitable for both research and applied sports settings.
Stopwatch for Sprint Speed
A standard handheld stopwatch is used to measure sprint speed over set distance 30m. The assessor starts and stops the watch as the participant crosses the start and finish lines. The best time from two trials is recorded for analysis. Manual timing with a stopwatch is a practical and cost-effective method for field-based sprint assessment. Research shows that hand-held stopwatches have strong concurrent validity compared to electronic timing systems (R² = 0.981-0.994) and excellent inter-rater reliability (ICC = 0.980-0.994) when used by experienced raters. The typical measurement error is small (about 1.6-2.5%), making this method acceptable for sports performance testing.
