Plain-language summary
Trained sprinters received β-alanine over a loading protocol, after which muscle biopsies confirmed elevated carnosine and isokinetic testing showed reduced fatigue across repeated maximal bouts — a clean cause-and-effect chain in an already trained population.
Key takeaways
- ›Carnosine loading is achievable in elite athletes.
- ›Fatigue resistance improved on repeated efforts.
- ›Robust mechanistic and performance evidence.
