Episode notes
Bicarb Benefits May Grow Late In Events
- Bicarb's benefit in the 40K trial grew in later quartiles, suggesting effects may amplify toward the end of prolonged high-intensity efforts.
- That pattern supports a plausible role for acid-buffering or sodium effects late in hard events.
Watch For Sodium Confounds In Bicarb Studies
- When interpreting bicarb studies, check whether placebos matched sodium; unmatched sodium may confound performance effects.
- Use sodium-matched controls or be cautious attributing benefits solely to buffering if sodium differs.
High-Dose CBD May Calm But Not Boost Speed
- CBD at very high acute doses (300 mg) reduced anxiety and RPE but did not improve short time-trial performance.
- Consider CBD only for anxiolytic reasons and weigh contamination and dosing risks before routine use.
