EFFECT OF BETA-ALANINE SUPPLEMENTATION ON NEUROMUSCULAR PERFORMANCE. AN UPDATE

 

RETIRADO 

 

ABSTRACT

 

The aim of this review is to analyze the ergogenic effects of beta-alanine supplementation on neuromuscular performance. The material used includes those researches of the effects of beta-alanine on strength and on cyclic anaerobic exercises (duration <60 seconds) (years: 2007-2016). The result of this research is a broad analysis of the subject, which provides basic knowledge needed on this specific area. A critical review of the literature shows that the effects of beta-alanine on neuromuscular performance are not very clear in relation to the different strength exercises, the different Wingate tests and the specific anaerobic performance tests in real situations of competition (i.e., 30-second time trial, 200 yards (yd), 300 yd, and 400-meter straight). The data analyzed do not reveal differences depending on whether they are trained individuals or not. Therefore, the ergogenic effects of this supplement need more confirmation when it comes to high intensity exercises that require high levels of muscle strength / power. However, in repeated sprint exercises (sprint duration <7 seconds), beta-alanine and the combination of beta-alanine and sodium bicarbonate do not appear to improve performance because the improvement in buffer capacity does not dictate this type of evidence. There is some ambiguity regarding the combination of creatinine and beta-alanine supplementation, as well as limitations on its additive effect in relation to beta-alanine supplementation alone. There is no benefit from supplementation in the physiological parameters of body composition.
