Study Overview
Brief Summary
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.

Arms & Interventions
Amateur Soccer Players
Male licensed amateur soccer players competing in amateur soccer leagues. Participants underwent the same assessment protocol as the professional group. No intervention was administered.
Intervention: Physical Performance Assessment (Other)
Professional Soccer Players
Male licensed professional soccer players competing in professional soccer leagues. Participants underwent assessments of functional movement, dynamic balance, lower extremity muscle strength, eccentric hamstring strength, and jumping performance. No intervention was administered.
Intervention: Physical Performance Assessment (Other)
