Influence of follicular vs. Luteal phases on sweat rate and estimated sodium loss in university female football players: A field-based within-subject study. Applied Sciences, 16(8), 3912. https://doi.org/10.3390/app160839122076-3417https://hdl.handle.net/11268/17078This study examines the influence of the follicular (FP) and luteal phases (LP) of the menstrual cycle on sweat rate, estimated sweat sodium concentration, heart rate, hydration status, fluid intake, and perceived exertion in first-division university female football players. A small sample of eight athletes completed two monitored training sessions, one in each estimated-menstrual phase, following a repeated-measures field-based design under habitual training conditions.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Ciencias del deportejournal article10.3390/app16083912open accessDeporteAtletaInvestigación médicaGoal 3: Ensure healthy lives and promote well-being for all at all ages
