This observational repeated-measures methodological study evaluated the reliability and agreement of a 15-m linear sprint test performed on sand and firm surfaces in male beach-sport athletes. Participants completed three maximal sprint attempts on each surface during up to two testing sessions conducted on separate days. The study examined trial-to-trial reliability within each session, stability between testing days, and concordance between sprint times obtained on sand and firm surfaces. No therapeutic or training intervention was administered. Sand and firm surfaces were used exclusively as assessment conditions.
