Womenâs different hydration needs havenât been recognized until now because while womenâs participation in sports has increased significantly over the last severalÂ decades, research on women in sports has lagged. Until very recently, most of the data collected in case studies regarding nutrition and training were conducted largely on men. Women were deemed âtoo difficultâ to be included because of female hormone fluctuations.
Women have an altered energy metabolism during exercise, which impacts how they recover. Their recovery window is smaller and they have a predisposition to become overtrained if they go for too much intensity at different parts of their periods.
During the high hormone phase, estrogenÂ reduces the availability of carbohydrate and increases the amount of fat used for fuel; thus women have problems hitting intensities. Elevated progesterone increases womenâs core temperature byÂ ~0.5âC, it increases their total body sodium losses, and increases womenâs muscle breakdownâat the same time, reducing a womanâs ability to synthesize muscle. The combinationÂ of elevated estrogen and progesterone drops a womanâs available plasma volume by ~8%, and withÂ concurrent shifts in baseline thresholds, makes females more predisposed to hyponatremia, abnormally low blood sodium.
Finally, the recovery window for men and women is different. Women have 30 minutes for acute recovery and only 3 hours to eat a balanced meal for glycogen recovery.Â Soâyour girlfriend, wife or daughter may not just being unjustifiably moody when you take her on that five hour mountain-bike ride. She may not have the juice because her hormones are wreaking havoc with her ability to perform.
