How protein boosts muscle mass

You’re probably well aware of the scientific fact that optimal weight training gains are reliant on consuming enough complete protein – typically 1.8-2g daily per kg of body mass for a relatively lean athlete (e.g. 80kg x 2 = 160g protein). But how does protein actually build muscle?

TRAINING CREATES THE POTENTIAL FOR PROTEIN SYNTHESIS

When talking protein and muscle growth, it’s worth starting at the beginning of the repair and growth cycle – the training! Hardcore weight training causes micro trauma to muscle cells, providing the stimulus for accelerated protein synthesis and muscle build-up. In other words, to put extra quality protein to work (whether it’s steak or whey protein) – you need to hit the gym hard!

THE HORMONAL TRIGGER FOR PROTEIN UTILISATION

The damage sustained during weight training signals the release of a cascade of anabolic hormones, including GH, testosterone, Hepatocyte Growth factor, Fibroblast Growth factor, IGF-I and IGF-II. This is where the science gets mind boggling, but studies confirm that hormones play a critical role in the migration of ‘satellite cells’ to the muscle damage. When provided with sufficient protein, these powerful cells enable muscles to generate new contractile tissue, increasing muscle size.

– IGF 1 triggers protein synthesis
– GH stimulates amino acid uptake for muscle construction
– Testosterone boosts GH release, amino acid utilisation, satellite cell activity and protein synthesis

Healthy hormones are therefore critical to ensuring maximum benefit from a protein-rich muscle growth diet. Supplementing with ZMA PLUS HARDCORE™ or TESTODRIVE HARDCORE™ provides effective natural support thanks to zinc and Vitamin B6 which is involved in hormone regulation.

Consuming rapidly absorbed amino acids during training (BCAA INTRA HARDCORE™ or AMINO INTRA RIPPEDCORE™) is another potent strategy to support this growth environment.

DELIVERING PROTEIN TO TRAINED MUSCLES

Ingested proteins are broken down by digestive enzymes into single amino acids in the gastro-intestinal tract. They’re then able to pass into the bloodstream to supply muscles with the amino acids they need for repair and growth via training-induced satellite cell and hormonal activity. One benefit of PROTEIN SUPPLEMENTS is the different rates of amino acid delivery from nutrients such as whey (fast amino acid release for a rapid spike in protein synthesis) and casein (slow amino acid release to combat muscle breakdown for up to 8 hours).

In simple terms, the muscle growth formula = intense training + healthy hormones + optimal protein.
