This observational comparative study aims to evaluate differences in functional movement quality, dynamic balance, lower extremity muscle strength, and jumping performance between professional and amateur male soccer players. A total of 144 licensed soccer players (72 professional and 72 amateur) will undergo standardized assessments, including the Functional Movement Screen (FMS), Y-Balance Test (YBT), countermovement jump (CMJ), vertical jump (VJ), one-repetition maximum (1RM) strength tests, and eccentric hamstring strength assessment using the NordBord system. The findings are expected to improve understanding of how competitive level influences physical performance characteristics and may contribute to the development of evidence-based training, injury prevention, and athlete development strategies.
