Episode notes
Bicarb Research Origins
- Dr. Andy Sparks' research group investigated individualized bicarb responses after a 2014 paper by Jones.
- This led to a sprint study with varied bicarb doses and timings, revealing significant performance variability.
Bicarb's Multifaceted Mechanism
- Bicarbonate buffers hydrogen ions and speeds their removal from muscles, enhancing contractility.
- It also optimizes carbohydrate turnover, potentially improving performance in longer events.
Bicarb and Pain Perception
- While increased pH in muscles is a key benefit, bicarb's impact on pain perception needs further research.
- Focus on the established mechanisms when considering bicarb use.
