Branched-Chain Amino Acid Ingestion Stimulates Muscle Myofibrillar Protein Synthesis following Resistance Exercise in Humans. Frontiers in Physiology, 2017; 8 DOI: 10.3389/fphys.2017.00390

Popular muscle building supplements, known as branched-chain amino acids (BCAA) are ineffective when taken in isolation, according to new research from the University of Stirling. The study, involving the universities of Exeter and Birmingham and published in Frontiers in Physiology, show that while BCAA supplements do stimulate the muscle building response in individuals after they lift weights, other muscle-building supplements are far more effective.

Other supplements that contain all necessary amino acids stimulate a greater muscle growth response, which suggests that taking BCAA supplements alone is...

At the level of gene expression, PGC-1α is sensitive to numerous signaling cascades, most pronounced of which is the cAMP signaling pathway

Although both exercises activate PGC-1α gene (peroxisome proliferator-activated receptor-gamma coactivator), the adaptation processes stimulated are not the same and depend on the type of exercise.

Proteins run the body: They turn processes on or off or speed them up or slow them down. The body has many different proteins, and the instructions to make them are written on sections of DNA, referred to as genes. Different genes code for different proteins, but different proteins can also come from the same gene. Called isoforms, these proteins are produced when only part of the gene’s code is read.

The PGC-1α protein turns on other genes...
