Sodium bicarbonate reduces acute kidney injury risk during exercise in the heat 🥵
A strategy for performance and health?
Acute sodium bicarbonate supplementation reduces the increase in markers of acute kidney injury during physical work in the heat
Background
During exercise in the heat the kidneys are at higher risk of injury due to ⬇️ blood flow and ⬆️ metabolic cost of acid-based balance ⚠️
Due to sodium bicarbonate inducing metabolic alkalosis it may offer protective benefits 🧐
Study Details
This new study investigated the effects of ingesting 0.2 g/kg of sodium bicarbonate pre-exercise on…
markers of acute kidney injury🩸
…during exercise 2-hr walking at 65% of max heart rate in 40°C and ~ 20% relative humidity 🫀
Here is what they found ⬇️
Key Findings
Post-exercise markers of acute kidney injury (IGFBP7 + TIMP-2) were significantly lower after bicarbonate supplementation vs placebo 📉
Conclusion
Sodium bicarbonate may be a beneficial strategy for both performance and health ✅
Especially when exercising in the heat 🌡️
