Effect of β-alanine Supplementation and Training on Ergogenic Measures and Plasma Metabolites in Untrained Young Adults

This study enrolled untrained young adults to evaluate the effects of β-alanine supplementation combined with a structured exercise training program. Participants were randomly assigned to receive either β-alanine or a placebo while completing a six-week training regimen. Before and after the intervention, physical performance tests and blood samples were collected to assess changes in performance measures and biochemical markers in the blood. The purpose of the study was to determine how β-alanine supplementation influences exercise performance and related physiological outcomes in individuals who had not previously engaged in regular training.

Inclusion Criteria: * Healthy young adults aged 18-30 years. * Untrained individuals without participation in structured resistance or endurance training during the previous 6 months. * Not physically inactive, but not engaged in regular structured exercise training. * Ability to participate in a six-week supervised multicomponent exercise training program. * Willingness to comply with study procedures, training sessions, and supplementation protocol. * Provision of written informed consent. Exclusion Criteria: * Known cardiovascular, metabolic, neuromuscular, or musculoskeletal disease. * Acute injury at the time of enrollment. * Regular use of medications or dietary supplements affecting muscle metabolism or exercise performance. * Participation in structured resistance or endurance training during the previous 6 months. * Failure to comply with the study protocol or training requirements.
