Hypothesis
The co-ingestion of caffeine and sodium bicarbonate will enhance muscular endurance performance more than either supplement alone.
Conclusion
Caffeine improved muscular endurance performance, but the combination with sodium bicarbonate did not provide additional benefits and may have mitigated caffeine's effects.
Supporting Evidence
- Caffeine increased the number of repetitions performed in both bench press and back squat exercises.
- The combination of caffeine and sodium bicarbonate did not enhance performance compared to caffeine alone.
- Participants experienced gastrointestinal discomfort when consuming sodium bicarbonate with caffeine.
Takeaway
Drinking caffeine can help you do more push-ups and squats, but mixing it with baking soda doesn't make it better.
Methodology
Twenty-eight resistance-trained participants performed endurance tests after consuming caffeine, sodium bicarbonate, or a placebo in a double-blind, crossover design.
Potential Biases
Potential biases related to self-reported dietary habits and participant selection criteria.
Limitations
Plasma concentrations of caffeine and bicarbonate were not measured, which could provide insights into their effectiveness.
Participant Demographics
28 resistance-trained participants (14 males, 14 females; average age 23 years).
