Hypothesis
Combining beta-alanine supplementation with high-intensity interval training (HIIT) will enhance endurance performance and aerobic metabolism in recreationally active college-aged men.
Conclusion
HIIT is effective for improving aerobic performance, and beta-alanine supplementation may further enhance these benefits.
Supporting Evidence
- Significant improvements in VO2peak, VO2TTE, and TWD were observed after three weeks of training.
- Only the beta-alanine group showed significant increases in lean body mass after six weeks.
- Both groups improved in endurance performance, but the beta-alanine group had greater enhancements in the second training phase.
Takeaway
This study shows that doing intense exercise and taking a supplement called beta-alanine can help you run longer and get stronger.
Methodology
Forty-six college-aged men participated in a double-blind trial, receiving either beta-alanine or placebo while undergoing six weeks of HIIT.
Potential Biases
Potential bias due to self-reported dietary logs and the specific demographic of participants.
Limitations
The study only included recreationally active college-aged men, which may limit the generalizability of the findings.
Participant Demographics
College-aged men, recreationally active, aged 22.2 ± 2.7 years.
