Sodium bicarbonate enhances cycling performance in hypoxia 🧂🚴‍♂️ This new study investigated the effects of 0.3 g/kg sodium bicarbonate on cycling time-trial performance in acute hypoxia 🔍 🚵‍♂️ 14 trained cyclists were recruited to complete two conditions (placebo and bicarb) 🏔️ Acute hypoxia was 16.7 ± 0.2 FiO2 (~1,900 equivalent altitude) 💊 The sodium bicarb supplement was ingested 90 mins prior to exercise Results 📊 After sodium bicarb ingestion… ⏱️ 40-km time trial performance was enhanced by 1.2% 🩸 Blood pH and blood bicarbonate significantly increased pre-exercise and throughout There were also no significant differences in gastrointestinal symptoms between bicarb and placebo ✅ Sodium bicarbonate ingestion can enhances endurance performance in hypoxia and therefore should be a consideration for competing at altitude 📈 Reference: pubmed.ncbi.nlm.nih.gov/4148… Subscribe to Performance Nutrition Digest FREE to receive your daily study breakdown, straight to your inbox or via the Substack app 📥 performancenutritiondigest.c… Performance Nutrition Digest is powered by Healthspan Elite⚡️ healthspanelite.co.uk/

What’s (not) in your supplement?🔬 Previous evidence has raised concerns of the contents of various sports nutrition products🚨 This new study examined the contents of 8 popular commercially-available carbohydrate gels vs their label-stated nutritional contents 🔍 Here’s what they found… 📃 = claimed content 🔬 = actual content Gu Energy 📃 = 100 kcal / 23 g carbs 🔬 = 96.5 kcal / 23.9 g carbs Honey Stinger 📃 = 100 kcal / 23 g carbs 🔬 = 99 kcal / 24.7 g carbs Hüma 📃 = 100 kcal / 22 g carbs 🔬 = 91 kcal / 21.7 g carbs Maurten (100) 📃 = 100 kcal / 25 g carbs 🔬 = 103 kcal / 25 g carbs Näak 📃 = 200 kcal / 26 g carbs 🔬 = 176.5 kcal / 22.1 g carbs Precision Fuel (PF90) 📃 = 360 kcal / 90 g carbs 🔬 = 349 kcal / 85.9 g carbs Science in Sport (Beta Fuel) 📃 = 158 kcal / 40 g carbs 🔬 = 158 kcal / 39.2 g carbs Spring Energy 📃 = 180 kcal / 45 g carbs 🔬 = 53 kcal / 12.5 g carbs On average products contained significantly less energy than stated on the labels 📉 ⚠️ The Spring Energy fell outside of the 95% limits of agreement for both energy and carbs ⚠️ 👉 ~71% less energy (53 vs 180 kcal) 👉 ~72% less CHO (12.5 vs 45 g) These findings have performance, clinical and legal implications🚨
