Putative Role of rs1049434 Polymorphism in High-Intensity Endurance Performance: Concept and Basis to Understand Possible Individualization Stimulus.

Monocarboxylate transporters (MCTs) have been proposed as important mediators of the exchange between lactate (La) producer and La recipient (consumer) cells. Previous studies have suggested that the A1470T genotype could be related to different physical performance phenotypes. This study followed the guidelines for Strengthening the Reporting of Genetic Association Studies (STREGA) and aimed to evaluate the distribution of the polymorphism rs1049434 in endurance-trained athletes compared to the untrained population.
