Summary
The Barbell 1 Show breaks down a 2015 study by Griffin and colleagues from the International Journal of Sports Nutrition and Exercise Metabolism that tested four supplementation conditions in nine highly trained men: placebo (maltodextrin), creatine monohydrate (20g), sodium bicarbonate (0.3g/kg), and creatine plus baking soda combined. Participants performed six rounds of 10-second all-out Wingate bike sprints with one-minute recovery between each. The results showed creatine was the most effective supplement for peak power output and total work performed, while baking soda provided a smaller but measurable benefit. Combining the two showed minimal synergistic effect beyond creatine alone. The host notes that the 10-second sprint protocol may not be ideal for demonstrating bicarb's benefits, which likely shine more in sustained 2-3 minute efforts like 800m runs or high-volume bodybuilding sets with short rest periods. He also shares that US Olympic athletes have been using sodium bicarbonate supplementation behind the scenes.
Key Points
- Study tested creatine (20g), baking soda (0.3g/kg), creatine + baking soda combo, and placebo over 7-day loading periods
- Creatine was the most effective supplement for repeated 10-second all-out sprints
- Baking soda provided a smaller but measurable performance benefit on its own
- Combining creatine and baking soda showed no meaningful synergy beyond creatine alone for this protocol
- Bicarb likely works better for sustained 2-3 minute efforts where acidosis is the primary limiter, not short 10-second sprints
- Baking soda creates an alkaline extracellular environment that draws acidic byproducts out of working muscle cells
- Take baking soda 90 minutes to 2 hours before exercise to avoid GI distress
- US Olympic athletes have reportedly used sodium bicarbonate supplementation for short-duration intense events
Key Moments
Study breakdown — creatine vs baking soda vs combo for sprint performance
The host breaks down a 2015 study by Griffin et al. that tested creatine (20g), baking soda (0.3g/kg), their combination, and placebo in nine trained men doing repeated 10-second Wingate sprints. Creatine was most effective; baking soda helped to a lesser degree; the combo showed minimal synergy beyond creatine alone.
"supplement, but baking soda was effective to a lesser degree. However, any synergistic effect"
How baking soda works as an extracellular buffer
The host explains baking soda's mechanism: it creates an alkaline extracellular environment that draws acidic byproducts out of muscle cells, counteracting the acidosis that contributes to fatigue during high-intensity exercise.
"which is the opposite of acidic. So it helps to balance these conditions out. The baking soda is"
Where baking soda really shines — sustained high-intensity efforts
The host argues that 10-second sprints are the wrong test for baking soda. Its real benefit is in sustained 2-3 minute all-out efforts like 800m runs or high-volume bodybuilding sets with short rest periods, where acidosis is the primary performance limiter.
"be helpful for more like that 800 meter run. Um, something that's, you know, two, three minutes in"
US Olympic athletes quietly using baking soda supplementation
The host reveals that a friend working with a US Olympic team found that most athletes on the team were supplementing with sodium bicarbonate, illustrating how elite athletes often rely on basic, inexpensive supplements rather than complex cocktails.
"US Olympic team for a certain particular sport. And if I do remember correctly, they were,"
