Effect of β-alanine supplementation during high-intensity interval training on repeated sprint ability performance and neuromuscular fatigue.

Article Synopsis
- The study examined how β-alanine supplementation affects repeated sprint ability (RSA) during high-intensity interval training (HIIT) in men.
- Participants completed a 4-week HIIT program followed by a 6-week phase where one group received β-alanine (Gβ) and the other a placebo (GP).
- Results showed that β-alanine significantly improved muscle carnosine levels and reduced neuromuscular fatigue compared to the placebo, enhancing overall sprint performance.
This study examined the physiological responses during exercise-to-exhaustion at the lactate-minimum-intensity with and without prior high-intensity exercise. Eleven recreationally trained males performed a graded exercise test, a lactate minimum test and two constant-load tests at lactate-minimum-intensity until exhaustion, which were applied with or without prior hyperlactatemia induction (i.e.

Methods: This was a prospective cross-sectional study involving 21 patients (15 men) with mild-to-moderate COPD undergoing spirometry, handgrip strength (HGS) testing, cardiopulmonary exercise testing, and determination of lactate at peak exertion (LACpeak).
Results: Mean weight was 66.
