Abstract
In this study, we showed that females and males develop a similar hypoxia-induced impairment in endurance performance, perceived and performance fatigability during a 4-km cycling time trial. These novel findings indicate that females and males regulate their power output similarly during a 4-km cycling time trial under moderate hypoxia, likely to avoid prematurely exacerbating metabolic disturbances and thereby reaching comparable levels of performance fatigability by the end of the task.Keywords
