ABSTRACT

Background Early research with beta-alanine (b-ALA) supplementation has shown increases in muscle carnosine as well as improvements in body composition, exercise performance and blood lactate levels. Creatine monohydrate supplementation has been extensively researched for its effects on anaerobic exercise performance. Recently, studies have examined the combined effects b-ALA and creatine supplementation on anaerobic exercise performance and lactate threshold. The purpose of the present study was to examine the acute and chronic effects of b-ALA supplementation with and without creatine monohydrate on body composition, aerobic and anaerobic exercise performance, and muscle carnosine and phosphagen levels in college-aged recreationally active females.
