Episode highlights:

(17:53) Theory on hormone cycles and hydration: estrogen and progesterone can impact nutrition needs, performance, brain function, investigating fluid and electrolyte balance

(25:27) Practical considerations for females: no meaningful differences in hydration for female athletes versus males or across different phases of their cycle, no performance differences, avoiding overhydration, cross-cycle variations in core temperature are insignificant

(36:23) Sweat testing: Precision Hydration sweat testing at CTS, sweat testing protocol, menstrual cycle phase does not impact results
