Carnosine is a skeletal muscle potent H+ buffer that is suggested to reduce acidosis during high-intensity exercise. Carnosine synthesis is highly limited by the Beta-Alanine (β-Ala) availability. Therefore, the aim of this study was to investigate the effect of 7 days of β-Ala supplementation on 30-sec cycle ergometer Wingate test parameters. Total of 16 healthy active subjects (10 males and 6 females) [32.2±4.8 years, 81.3 ± 15.9kg, and 173.8±8.9 cm] were pre-tested on 30-sec maximal ergometer cycling Wingate test. They were thereafter assigned randomly to a treatment group (β-Ala) and control group (Con). Subjects in β-Ala received a 15 g of flavored β-Ala (5 g β-Ala, 10 g of dextrose), while Con received a 15 g of dextrose only (placebo). After supplementation, subjects performed the same maximal ergometer cycling test. Only Peak and mean RPM increased from pre- to post-supplementation in β-Ala (P< 0.01), but not in Con (P ＞ 0.3).The percent change from pre- to post-supplementation was greater in β-Ala than Con. Total work done was not affected by the β-Ala despite the increase in peak and mean RPM. These data shows that 7 days of β-Ala supplementation does not improve cycle ergometer Wingate test performance. Increased RPM is not a necessary indicator of elevated total power output during maximal cycling.
