Insulin action on beta-alanine uptake by skeletal muscle: effect on muscle beta-alanine content and mechanisms involved

, 2019
A disponibilidade de beta-alanina é o fator limitante para a síntese intramuscular de carnosina. Dessa maneira, aumentar a disponibilidade de beta-alanina para o músculo esquelético é a estratégia mais eficaz para aumentar o conteúdo de carnosina ...

A carnosina diminui os efeitos da acidose muscular durante o exercício

Revista Brasileira de Nutrição Esportiva, 2015
A carnosina é um dipeptídeo composto pelos aminoácidos beta-alanina e histidina encontrado em maior parte no tecido muscular. Sua síntese ocorre através da enzima carnosina sintase tendo a beta alanina como precursor limitante. Estudos tem mostrado que o

Beta-alanine Suppresses Heat Inactivation of Lactate Dehydrogenase

, 2005
Beta-Alanine exhibits neurotransmitter activity and is a component of the anti-glycation agent carnosine. We propose that beta-alanine may have additional properties which may be of physiological significance. Interestingly, stress modulates the level of

The Effects of a Multi-Ingredient Performance Supplement Combined with Resistance Training on Exercise Volume, Muscular Strength, and Body Composition

Sports, 2019
The effects of a multi-ingredient performance supplement (MIPS) incorporating a mixture of branched chain amino acids, beta-alanine, glutamine, creatine, and piperine on resistance training (RT)-induced adaptations remains unclear. Therefore, the purpose
