Resumen
Objetivo: Evaluar los efectos de los probióticos sobre el rendimiento de individuos que practican ejercicio físico, centrándose en la fuerza muscular. Métodos: La investigación se realizó a través de una revisión integradora de la literatura, abarcando 11 estudios publicados entre 2010 y 2025. La revisión siguió seis pasos metodológicos: formulación de la pregunta de investigación, búsqueda de literatura, recolección de datos, análisis crítico de los estudios, análisis de los resultados y presentación de los hallazgos. La pregunta guía fue: "¿El uso de probióticos promueve beneficios en el rendimiento de las personas que realizan ejercicio físico?". Se analizaron ensayos clínicos aleatorizados, con descriptores como “Probióticos”, “Ejercicio” y “Fuerza muscular” en las bases de datos PubMed, BVS, EBSCOHost, ScienceDirect y CAPES. Resultados: El análisis identificó 11 artículos, la mayoría publicados en revistas Qualis A1 (45,45%). Taiwán fue el país con mayor número de publicaciones (36,36%). Los ensayos clínicos aleatorios dominaron la metodología, con participantes tanto deportistas como sedentarios. Los resultados mostraron que el uso de probióticos, como Lactobacillus y Bacillus coagulans, se asocia con mejoras en la fuerza muscular y el rendimiento físico. Consideraciones finales: Los probióticos, asociados al ejercicio regular, proporcionan un aumento de la fuerza muscular, resistencia y potencia explosiva, además de acelerar la recuperación post-ejercicio, reduciendo los marcadores inflamatorios relacionados con el daño muscular.
