In the pursuit of better performance, endurance athletes—particularly runners—are always searching for ways to maximize their potential. While many performance-enhancing drugs are banned, there are a few legal substances that can offer significant benefits, and one such aid is bicarbonate of soda, or baking soda.
Baking soda is not just a kitchen staple; it’s gaining recognition in the sports world for its ability to boost endurance and delay fatigue during high-intensity exercise. But how exactly does it help athletes, and how should runners use it for maximum benefit?
The Science Behind Baking Soda for Performance
Buffering Against Lactate Build-Up
When runners engage in high-intensity exercise, their muscles burn glucose for energy, producing lactic acid as a byproduct. As lactic acid accumulates, it dissociates into lactate and hydrogen ions (H+), which lower the pH level in the muscles, causing an acidic environment. This muscle acidity can lead to fatigue, reduced muscle function, and that familiar "burn" runners experience during hard efforts.
Bicarbonate of soda is a natural buffer that helps neutralize this acidity. When ingested, it increases the body's bicarbonate levels in the bloodstream. This enables the muscles to manage the acid build-up more effectively, delaying the onset of fatigue. In simpler terms, bicarbonate acts as a shield, allowing the muscles to keep performing at a high level for longer.
Improved High-Intensity Performance
Studies have shown that taking bicarbonate of soda before exercise can significantly enhance performance in events lasting from 1 to 7 minutes, such as middle-distance runs, sprints, or interval training. Even in longer endurance events like the marathon, where intermittent high-intensity efforts are necessary (such as surges or uphill running), the buffering action of bicarbonate can still prove beneficial.
How Much Bicarbonate of Soda Should You Use?
While the benefits of bicarbonate are clear, the correct dosage is crucial to avoid any gastrointestinal discomfort—a common side effect when taking too much.
- Recommended Dosage: The optimal amount of bicarbonate of soda is generally around 0.2 to 0.3 grams per kilogram of body weight. For instance, a 70 kg (154 lbs) runner would need between 14 to 21 grams of baking soda.
- Timing: Bicarbonate should be ingested 60 to 90 minutes before exercise to allow time for it to enter the bloodstream and start buffering. You can mix it with water or a sports drink to make it easier to consume.
- Avoid Stomach Issues: Baking soda is known to cause gastrointestinal discomfort, including bloating, gas, and diarrhea, especially when taken in large amounts. To reduce this risk, many athletes opt to take the dose over several smaller servings or mix it with food. Alternatively, splitting the dosage into 2-3 smaller intakes spread over an hour can help minimise digestive issues.
Practical Tips for Using Bicarbonate of Soda
- Test It in Training: Don’t try using baking soda for the first time on race day! Test it during training sessions to see how your body reacts.
- Start Small: Begin with the lower end of the dosage range and gradually increase as you gauge your tolerance.
- Combine with a Carbohydrate-Rich Meal: Some runners find that consuming bicarbonate along with a carb-rich meal helps reduce stomach upset.
- Consider Enteric-Coated Capsules: For those who have trouble with baking soda's taste or digestion, enteric-coated bicarbonate capsules are an alternative. These capsules dissolve in the intestines instead of the stomach, which can help avoid discomfort.
Does It Work for Everyone?
While many runners experience noticeable performance improvements, bicarbonate of soda doesn’t work for everyone. Individual responses can vary based on factors such as gastrointestinal tolerance and the intensity of exercise. Research suggests that it’s most effective for high-intensity efforts lasting from 1 to 10 minutes. It may have limited benefits for purely aerobic efforts like long, slow runs, where lactic acid build-up is minimal.
Final Thoughts
For runners looking to enhance their performance legally, bicarbonate of soda can be a valuable tool. Its ability to buffer against muscle acidity allows athletes to sustain high levels of effort for longer, potentially giving them the competitive edge they’re looking for. However, as with any supplement, proper dosage and testing during training are essential to avoid unwanted side effects.
By incorporating baking soda into their performance routine, runners can tackle tough training sessions or races with increased endurance and reduced muscle fatigue, making this humble kitchen ingredient a secret weapon in the world of sports science.
