Relación entre la disfunción del core y el riesgo de lesión en extremidades inferiores en jugadores de voleibol amateur.

Abstract

Core stability underpins lumbopelvic control and jump performance in volleyball; deficits may elevate lower-limb injury risk. Simple, on-court screening can help flag athletes at higher risk. Objective: To examine the association between core dysfunction and the functional risk of lower-limb injury in amateur volleyball players. Methods: Cross-sectional analytic study of 40 athletes aged 14–18 years. Core endurance was assessed with the McGill Torso Muscular Endurance Test battery (trunk flexion, extensor/Sørensen, right/left side plank). Core dysfunction was defined as ≥1 of 4 tests below the age- and sex-specific 25th percentile. Functional risk was defined as Y-Balance Test (YBT) composite <94%. Proportions and odds ratios (ORs) with 95% CIs were estimated; Fisher’s exact test evaluated the association. Results: Core dysfunction: 55.0% (22/40). YBT <94%: 77.5% (31/40). The proportion with YBT <94% was higher in the dysfunction group than in the functional group (95.5% vs 55.6%), OR = 16.8; 95% CI 1.76–76.51; p = 0.0055. Conclusions: Core dysfunction is associated with greater odds of YBT <94% in amateur volleyball players. Combined McGill + YBT screening is feasible and useful for on-court functional risk stratification. No intervention was implemented at this stage.
