Beta Alanine
assssssssssssss
In the study, forty-six college-aged men who had not taken supplements within the past six months participated in two three-week programs of high-intensity interval training and either placebo or beta-alanine supplementation. Fitness assessments were taken prior to the program to find a baseline, and also at the midpoint and end of the study.
Even after only the first three weeks, several significant changes were noted between the beta-alanine group and the placebo group. Those supplementing beta-alanine demonstrated longer time until exhaustion and improved maximal oxygen consumption (VO2 Max). Additionally, the increase in Total Work in the beta-alanine group was nearly double that of the placebo group. The supplement group also experienced positive changes in lean body mass, while the placebo group did not.
