Abstract
Effect of β-Alanine Supplementation on Repeated Sprint Ability and Responses of Blood Lactate and Bicarbonate in Male Soccer Players
Highlights
Soccer players complete a competitive game with substantial high numbers of explosive powers, duels, accelerations, and repeated sprints (Varley & Aughey, 2013)
These activities are performed with high-intensity effort that may be associated with the accumulation of muscle metabolites, such as adenosine diphosphate (ADP), inorganic phosphate (Smith et al, 2009), and hydrogen ion (H+) (Hobson, Saunders, Ball, Harris, & Sale., 2012) contributing to muscle fatigue
The accumulation of intramyocellular H+ represents the major cause of muscle fatigue during high-intensity exercise and has been shown to inhibit the resynthesis of phosphocreatine (PCr) (Hobson et al, 2012), glycolysis (Lancha Junior et al, 2015), and disrupt the buffering system
Summary
Soccer players complete a competitive game with substantial high numbers of explosive powers, duels, accelerations, and repeated sprints (Varley & Aughey, 2013). These activities are performed with high-intensity effort that may be associated with the accumulation of muscle metabolites, such as adenosine diphosphate (ADP), inorganic phosphate (Smith et al, 2009), and hydrogen ion (H+) (Hobson, Saunders, Ball, Harris, & Sale., 2012) contributing to muscle fatigue. We speculate that BA supplementation may improve performance by the features of physicochemical buffers
