The Science of Ultra-Trail Running Nutrition

Baking soda supplementation

 

Dosing Sodium Bicarbonate

Now that the mind-numbing biochemistry is out of the way let’s talk about timing and dosing. According to the 2021 International Society of Sports Nutrition position stand: sodium bicarbonate and exercise performance, single-dose supplements of 0.2 to 0.3 g/kg of body weight show improvement in muscular endurance. For example, if you weigh 70kg, your dosing range would be 14 to 21 grams. It’s recommended to ingest it between 60 and 180 minutes prior to exercise in a minimum volume of 0.5 liters of water.

According to the same study, multiple-day protocols of supplementation are most effective in doses of 0.4 to 0.5 g/kg of body weight for three to seven days before competition.

Available Formulas

There are a variety of commercial formulations available. The grocery-store-variety baking soda from Arm and Hammer contains 0.6 grams of NaHCO3 per 1/8 teaspoon. Read the labels on baking soda products carefully and choose a product that just contains baking soda. Many products out there contain other additives, such as cornstarch. Also, make sure your product is fully dissolved in the water before ingestion. Drink slowly over 20 to 30 minutes. This may not be the most palatable concoction you’ve ever ingested; refrigeration can help with the taste as well as adding a very small amount of clear fruit juice or fruit-juice-based soda for flavoring.

Hydration for optimal health and performance | Stacy Sims, PhD | The Pro...


In this episode, we cover a range of topics related to hydration and its impact on physical performance. You'll learn about the basic biology of hydration, how to determine if you're properly hydrated, and whether water alone is sufficient or if we need to add electrolytes and glucose. We discuss how hydration needs change throughout the menstrual cycle, and how to calculate fluid requirements at an individual level. Dr. Sims shares her research findings and insights from working with athletes, debunking myths about hydration, including the effectiveness of coconut water and the role of caffeine. Additionally, we explore the differences in hydration requirements between men and women, as well as how to optimise hydration strategies for various activities, such as high-intensity interval training, resistance training, and endurance events. By the end of the episode, you'll have a deeper understanding of the science of hydration and practical tips to improve your own hydration strategies for better performance and overall well-being.
