The aim of present study is to see the effects of single dose of beta alanine on performance in weight lifters. 20 male weight lifters (age 23.95±1.23 years) were selected based on inclusion and exclusion criteria. Subjects wererandomly divided into two groups. After pretest measurements, group A (n=10) ingested beta alanine beverage and group B (n=10) consumed placebo drink (glucon Dplain). One hour later, subjects performed pushups to fatigue and immediately, posttest measurements were documented. After a wash out period of one week, crossing over of subjects was done. Group A consumed placebo beverage while group B had beta alanine beverage and same procedure was performed. Pre and post measurement of blood lactate, vertical jump height (VJH) and max was documented. Blood lactate values was significantly lower in beta alanine group 47.92% as compared to placebo 104.60% (p=0.0001). VJH was significantly higher in beta alanine group 6.30% as compared to placebo group 1.76% (p=0.0001). Reduction in VO2 max in beta alanine group 16.91% was significantly lesser when compared with placebo 41.21% (p=0.0001). It was concluded that ingestion of single dose of beta alanine significantly improves performance in weight lifters.
