dc.descriptionLa importancia de la Epo como hormona central en los procesos de ambientación a la altura es clara dado su efecto estimulante sobre la producción  eritrocitaria. Su naturaleza hormonal ha llevado a que algunas investigaciones evalúen su circadianidad con reportes no contundentes e inclusive contradictorios al respecto. Objetivo: Analizar la circadianidad de la Epo en sujetos que realizan entrenamiento aeróbico en la altura intermedia (2600 msnm) comparando diferencias entre hombres y mujeres. Materiales y métodos: Se reclutaron residentes a la altura intermedia de por lo menos 18 meses, de ambos sexos y que tuvieran entrenamiento aeróbico al menos durante 8 meses previos a la realización del estudio para medir su Epo cada 4 horas durante 24 horas y correlacionarla con algunas variables fisiológicas y ambientales. Resultados: Existe comportamiento circadiano en la Epo tanto para hombres como para mujeres, con un mesor para hombres de 20:10 h y 16:33 h para mujeres. En cuanto a la acrofase, esta se presenta hacia las 17:52 h para hombres y a las 15:50 h para las mujeres. El análisis de diferencia de medias muestra una diferencia estadísticamente significativa entre los dos grupos Conclusión: Existe circadianidad diferencial entre hombres y mujeres en cuanto a sus niveles de Epo, la cual es independiente de variables fisiológicas y ambientales. Tema: Ritmo circadiano. Subtema: Eritropoyetina.
