Context Arbitrary asymmetry thresholds are regularly used in professional soccer athletes, notwithstanding the sparse literature available to examine their prevalence. Objective To establish normative and positional asymmetry values for commonly used screening tests and investigate their relationships with jumping performance. Design Cross-sectional study. Setting Elite soccer screening. Patients or Other Participants A total of 203 professional male soccer players. Main Outcome Measure(s) Bilateral and unilateral jumping; range of motion; and hamstrings (HAM), quadriceps (QUAD), and hip-adductor and -abductor strength tests were used to quantify asymmetry. Players were divided into 4 quartiles (Q1–Q4) based on the magnitude of their asymmetry for each test. Single composite scores were also developed to group tests by range of motion and HAM, QUAD, hip-adduction, and hip-abduction strength, and differences in jump performance were examined among players in each quartile.
