[en] Introduction: Ankle-foot complex injuries occupy second place on the podium of the most frequent in the world of sport, specifically, female athletes present a greater risk of injury compared to their male counterparts. The influence of the menstrual cycle (MC) on the risk of anterior cruciate ligament (ACL) injury has been demonstrated, and there is no study that analyzes its influence on the risk of injury to the ankle-foot complex. Objetive: The aim of this final dissertation is to conduct a review of the existing literature in order to find out the influence of the menstrual cycle (MC) in the harmful incidence in the anklefoot complex, analyzing its effect on the different musculoskeletal structures of the athlete. Material and method: A search was carried out in the databases of PubMed, Cochrane Library Plus, SPORTDiscus, Web of Science and Scopus during the month of April 2021. Observational analytical studies were included, which analyzed during the MC different musculoskeletal variables that indicate harmful risk in eumenorrheic women who do not use oral contraceptives. Results: A total of 14 observational analytical studies were analyzed, with a low level of scientific evidence and grade of recommendation. Several variables were simultaneously examined in the different studies, 13 articles analyzed the mechanical properties of dynamic stabilizers, only 7 articles finding significant differences throughout the MC. 8 articles analyzed the mechanical properties of static stabilizers, obtaining significant changes in 5 articles. Only 1 article analyzed proprioception, without obtaining any relevant result and another 4 the dynamic postural control, obtaining significant variations in 3 articles. Conclusions: It can be stated after analyzing the results obtained, it can be affirmed that there is no common consensus that determines whether MC is really a risk factor for injury to the ankle-foot complex. Due to the poor quality of the existing studies, the heterogeneity of measurements and the variety of findings, the need for future studies that analyze the influence of MC on the incidence of injury in this anatomical region is pointed out.

[gl] Introdución: As lesións no complexo nocello-pé ocupan o segundo posto no podio das máis frecuentes no mundo deportivo, concretamente, as atletas femininas presentan un maior risco de lesións en comparación aos seus homólogos masculinos. Demostrouse a influencia do ciclo menstrual (CM) no risco de lesión do ligamento cruzado anterior (LCA), non existindo como tal ningún estudo que analice a súa influencia no risco lesivo no complexo nocello-pé. Obxectivo: O obxectivo deste traballo é realizar unha revisión da literatura existente ca finalidade de averiguar a influencia do CM na incidencia de lesiva no complexo nocello-pé, analizando o seu efecto sobre as diferentes estruturas musculo-esqueléticas da deportista. Material e método: Levouse a cabo unha busca nas bases de datos de PubMed, Cochrane Library Plus, SPORTDiscus, Web of Science e Scopus durante o mes de abril de 2021. Incluíronse estudos analíticos observacionais, que analizaran ao longo do CM diferentes variables músculo-esqueléticas indicadoras de risco lesivo en mulleres cunha función menstrual normal non consumidoras de anticonceptivos orais. Resultados: Analizáronse un total de 14 estudos analíticos observacionais, cun baixo nivel de evidencia científica e grao de recomendación. Examináronse simultáneamente diversas variables nos diferentes estudos, 13 artigos analizaron as propiedades mecánicas dos estabilizadores dinámicos, atopando só 7 artigos diferenzas significativas ao longo do CM. 8 artigos analizaron as propiedades mecánicas dos estabilizadores estáticos, obtendo cambios significativos en 5 artigos. Só 1 artigo analizou a propiocepción, sen obter ningún resultado relevante e outros 4 o control postural dinámico, obtendo variacións significativas en 3 artigos. Conclusións: Tras analizar os resultados obtidos, pódese afirmar a inexistencia dun consenso común que determine se o CM é realmente un factor de risco lesivo no complexo nocello-pé. Debido á mala calidade dos estudos existentes, á heteroxeneidade das medidas e á variedade de achados, sinálase a necesidade de futuros estudos que analicen a influencia do CM sobre a incidencia de lesiva nesta rexión anatómica.
