Dr. Stacy Sims, Osmo Co-Founder and Chief Research Officer, has announced a new line of Osmo performance products reformulated for the specific needs of women.
"The estrogen and progesterone in our bodies impacts our performance as athletes," explains Dr. Sims. "I formulated Osmo for Women products based on findings that I and other scientists have published in peer
reviewed journals to address these effects, enabling women to improve power output and endurance, avoid premenstrual performance decline and optimize training adaptations. Female athletes will be amazed by how much better they feel and perform when they get the
nutrition that matches their physiology"
O&A WITH DOCTOR SIMS
Why Hasn’t Someone created Products Like this Before?
While the participation of women in sports has increased significantly over the last several
decades, research of women in sports has lagged behind that of men. Besides the obvious
differences, women have a physiology that is different than men and until very recently, most of
the data collected in case studies regarding nutrition and training were conducted largely on men
that’s great for the guys; but women have a menstrual cycle that impedes generalizing what’s
good for a man must be good for a woman.
Has research of women in sports lagged behind that of men?
Yes, primarily because women have
been deemed “too difficult” to be included in research because of these hormone fluctuations.
How do estrogen and progesterone affect female athletes?
For starters, women have an altered energy metabolism during exercise which completely
impacts how we recover. Our recovery window is smaller and we have a predisposition to become
over trained if we do too much intensity at different parts of our periods. During the menstrual cycle, we have two hormone phases: high and low. During the low hormone phase, our carbohydrate metabolism and recovery are closer to men’s and we are able to complete high intensity workouts. However during the high hormone phase, estrogen
reduces the availability of carbohydrate and increases the amount of fat used for fuel; thus we
have problems hitting intensities. Elevated progesterone increases our core temperature by
~0.5’C8, increases total body sodium losses, and increases muscle breakdown (and at the same time, reduces the body’s ability to synthesize muscle). If this wasn’t enough, the combination
of elevated estrogen and progesterone drops our available plasma volume by ~8%; and with
concurrent shifts in baseline thresholds, makes us more predisposed to hyponatremia. 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.
To address these physiological realities I have developed and tested three formulas that Osmo is brining to market now. These formulas are based on research that I and other scientists have
published in peer reviewed journals. It is my sincere hope that multitudes of female athletes will
use these products and experience how much better they feel and perform when they get the
nutrition that matches their physiology.
