Osmo Nutrition Debuts, Takes Hydration & Recovery to a Whole ‘Notha Level
Ready to geek out on some nutrition science?
OSMO Nutrition is a new sports nutrition company based on the research of Dr. Stacy Sims, an exercise physiologist and sport nutritionist at Stanford University from 2007-2012 with an impressive resume of consulting Lance Armstrong and other top athletes over the years. She’s also a Cat 1 roadie and elite XTerra triathlete.
The name Osmo is a play on Osmolality, the measure of how many solutes (solids) are in a solution. The key with sports drinks is to have the osmalality lower than that of your blood in order to be absorbed quickly. Otherwise, you’re stomach has to work to dilute it.
Sims says most sports drinks are designed to be a fuel source and pack in lots and lots of calories. By packing all that in, it increases the osmolality too high, which hurts absorption. This causes water to be pulled to the digestive system to dilute it, which means it’s being pulled away from your muscles.
Her guideline for athletes is “food in your pocket, hydration in your bottle. If you’re relying on fuel from your liquids, you’re not optimizing your hydration.”
Sims actually doesn’t recommend gels at all, a theory shared with another former Armstrong support member, Dr. Allen Lim. She says for every one gel, you should probably consume 8-12 ounces of water, but even then it’s a concentrated source in the stomach that requires time to mix with the water before it can digest. It also causes heat storage because most gels are comprised of fructose or maltodextrin, which require an extra step for digestion. This extra step produces heat, which is just added to the heat already being produced by your muscles. This decreases the time to fatigue.
Food’s a little different, surprisingly. She recommends simple carbs like white bread or new potatoes with some salt or peanut butter on them. Nothing that’s going to spike the blood sugar too much or cause stomach distress.
OK, with all that in mind, just what sort of drinks did they develop?
