The Science and Innovation of Protein Blitz

The Science of PROTEINBLITZ

Hard workouts, hard muscles -- backed up by hard science.

NANO-FILTRATED WHEY PROTEIN ISOLATE

Nano-filtration is the most scientifically advanced form of micro-filtration, ultra-filtration to produce the purest whey protein isolate. Our whey is produced at a very low temperature that allows for high protein purity levels and maintains important protein fractions, with nearly no denatured proteins. No chemical or reagents are used, like those found in other whey protein isolate such as ion exchange.

BRANCHED CHAIN AMINO ACIDS (BCAAs)

PROTEINBLITZ whey protein isolate is packed high levels of the branched chain amino acids (BCAAs). BCAAs are mostly metabolized by skeletal muscle, unlike the other amino acids, which are metabolized by the liver. The enzyme responsible for BCAA metabolism is called Branched Chain Keto Acid Dehydrogenase, which is highly concentrated in human skeletal muscle. Because of this metabolic fate, BCAAs can be called muscle fuel, and are probably the most important combination of amino acids to improve muscle performance and function.

BCAAs' KEY METABOLIC ROLES

• BCAAs act as substrates for energy production. The complete oxidation of leucine in the muscle yields more adenosine triphosphate molecules than the complete oxidation of glucose. In plain English, leucine can provide muscle with more usable energy than an equal amount of glucose.

• To meet the demand for BCAAs during exercise, the body will sacrifice muscle tissue to supply the additional BCAAs. Whey protein during exercise can supply BCAAs to meet that demand so muscle is not being broken down.

• BCAAs are key initiators of protein synthesis -- especially the BCAA leucine, which can stimulate protein synthesis through insulin secretion and activation of mammalian target of rapamycin (mTOR). This is working on the genetic level for protein synthesis.

• BCAAs are the initiator of the Pax7 gene, a marker for satellite cell activation. Satellite cell activation is responsible for the regeneration and proliferation of new muscle fibers.

RESEARCH

It's not just us! Whey protein's benefits have been proven in rigorous studies.

• Whey protein's effect on the mTOR signaling pathway and myostatin: The results indicate that resistance exercise increased mTOR initiation, which may decrease the expression of myostatin. Whey protein increased and prolonged the mTOR signaling response and thus increased protein synthesis.

Hulmi, JJ, et al. Resistance exercise with whey protein ingestion affects mTOR signaling and myostatin in men. Jour. App. Physiol. Vol. 106, No 5, pp. 1720-1729. 2009.

• Seven men participated in an intense bout of unilateral resistance exercise followed by the consumption of 25g of whey protein to maximally stimulate protein synthesis. The results: Myofibrillar and sarcoplasmic protein synthesis are stimulated by protein feeding. Resistance exercise rapidly stimulates and sustains the production of myofibrillar protein after protein ingestion.

• Fifteen subjects ingested whey protein or an equivalent amino acid composition as free-form amino acids. Whey protein improved skeletal muscle accrual through mechanisms not explained by the essential amino acid content. There is evidence that whey protein enhances anabolism by some unexplained mechanism not directly related to the amino acid make-up.

Katsanos, CS, et al. Whey protein ingestion in elderly persons results in greater muscle protein accrual than ingestion of its constituent essential amino acid content.

• Whey protein is rich in specific amino acids, such as leucine. Whey protein rapidly produces a rise in blood amino acid levels, necessary for preserving lean muscle. Simply adding dietary whey protein and resistance exercise may spare muscle mass.

• Study aimed at results produced by consuming whey protein on stimulating protein synthesis. Eight healthy men participated in the double-blind randomized crossover trial. Subject performed a 1 leg exercise, 4 set of 8-10 repetitions, the other leg was not exercised. Exercise stimulated a rise in protein synthesis and was greater in the whey group than in the carbohydrate group. Ingesting whey protein after exercise supports positive net protein balance, and thus hypertrophy or muscle growth.
