Beta-alanine for repeated sprint performance - does it deliver? ⚡️
Benefit or bust.
No ergogenic effect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials
Study Details
This new meta-analysis compiled data from 17 studies to establish the effects of beta-alanine on repeated sprint ability (RSA) 📚
Here is what they found ⬇️
Key Findings
🗓️ Intervention duration ranged from 3 - 10 weeks
💊 Daily dosages varied between 3.2 and 6.4 g/day
⚖️ Total doses ranged from 134.4 to 268.8 g
Results showed that beta-alanine ingestion had no significant effect on…
❌ Mean RSA performance
❌ Peak RSA performance
❌ Fatigue decrement
Further analysis showed that these findings were not significantly moderated by total administered dose, duration, exercise modality, or training status ⚠️
Conclusion
Chronic beta-alanine supplementation does not provide a clear benefit to repeated sprint ability 🙅♂️
All buzz. No benefit.
