  1. ICC ≥ 0.90 – excellent reliability, 0.75–0.90 – good, 0.50–0.75 – moderate. Pearson’s correlation coefficient (r) confirmed strong associations between test and retest measurements across sprint types and parameters. SEM (s) – Standard Error of Measurement, indicating typical measurement error; smaller values reflect higher precision. MDC95 (s) – Minimal Detectable Change at 95% confidence; a change greater than this value is considered statistically significant. Data were collected in Deaf basketball players (n = 11).
