Specific Protein Linking Exercise To Muscle Hypertrophy

The previously unidentified protein in muscles which spurs growth and increased strength following resistance exercise has finally been discovered by scientists.

The protein is called PGC-1 alpha 4. The study in which the protein was isolated and tested found that resistance exercise caused a rise in PGC-1 alpha 4 which triggered biochemical changes that increased muscle size and strength.

The protein is an isoform (slight variant) of PGC-1 alpha which is an important regulatory protein of metabolism, activated by forms of exercise which increase muscular endurance (ie running).

There are suggestions that artificially raising PGC-1 alpha 4 levels may someday be used to prevent muscle wastage in patients suffering from chronic diseases or acute injuries, although I am sure that some may wish to use it as the lazy way to gain lean muscle mass!
