Reliability and Concordance of 15-metre (15-m) Sprint Performance on Sand and Firm Surfaces

2026年6月9日 更新者：Édison Andrés Pérez Bedoya、Federal University of Vicosa

Within-Session and Between-Day Reliability of the 15-metre (15-m) Sprint on Sand and Firm Surfaces, and Concordance Between Conditions, in Male Beach-Sport Athletes

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.

详细说明

Male athletes participating in beach soccer, beach volleyball, or beach handball completed three maximal 15-m linear sprint attempts on both sand and firm surfaces. Each attempt was performed from a standardised standing start, with at least two minutes of passive recovery between attempts.

Testing comprised up to two sessions per participant on separate days. The order of the surface conditions was counterbalanced to reduce potential order and fatigue effects. Participants who attended two sessions completed the surfaces in the opposite order during the second session.

The primary measured variable was 15-m sprint time in seconds. The arithmetic mean of the three attempts and the fastest individual attempt were calculated for each surface and session. Within-session and between-day reliability were evaluated using intraclass correlation coefficients, coefficients of variation, standard errors of measurement, typical errors, and minimal detectable changes. Agreement between sand and firm-surface measurements was assessed using Lin's concordance correlation coefficient and Bland-Altman analysis.

研究人群

The study population consisted of male athletes participating in beach soccer, beach volleyball, or beach handball in Antioquia, Colombia. Participants were recruited using convenience sampling based on their availability during the data-collection period. Eligible athletes had completed at least six months of regular beach-sport training. Athletes with a musculoskeletal injury during the preceding six weeks, an acute illness during the preceding seven days, or who were unable to complete at least one full testing session were excluded.

  • Able to complete maximal 15-m sprint assessments on sand and firm surfaces.
  • Provision of written informed consent before participation.

Exclusion Criteria

  • Musculoskeletal injury during the six weeks preceding testing.
  • Acute illness during the seven days preceding testing.

设计细节

队列和干预

团体/队列
Male Beach-Sport Athletes
Sixteen male athletes participating in beach soccer, beach volleyball, or beach handball completed repeated 15-m sprint assessments on both sand and firm surfaces. Each participant performed three maximal sprint attempts per surface during each completed testing session. Ten participants completed two sessions on separate days, and six participants completed one session. No therapeutic or training intervention was administered; sand and firm surfaces were used exclusively as repeated assessment conditions to evaluate sprint-test reliability and between-surface concordance.

措施说明
大体时间
Mean 15-m Sprint Time on Sand and Firm Surfaces
大体时间：During up to two testing sessions, each lasting approximately 45 minutes, conducted on separate days within one week.
Time, measured in seconds, required to complete a maximal 15-metre linear sprint. For each surface and testing session, the outcome was calculated as the arithmetic mean of three maximal sprint attempts. For the between-surface analysis, one participant-level value per surface was derived by averaging session means for participants who completed two sessions or by using the single available session for participants who completed one session.
During up to two testing sessions, each lasting approximately 45 minutes, conducted on separate days within one week.
