The indoctrination machine of the supplement industry is pretty efficient. At least that's what I gather from the "bro-talk" in my own gym - I guess you know what I mean, right?

Bottom line: The logical conclusion Kanda et al. draw and I support is that their newest findings "indicate that WPH induces more rapid muscle recovery after exercise than does the AAM" (Kanda. 2014). Moreover, other specific gene changes relate to important transcription factors in skeletal muscle, which are also involved in the activation of the basal muscle anabolic protein Akt and a gene network these interacts with some glucoregulatory enzymes, such as hexokinase, pyruvate kinase and phosphofructokinase, which could explain why whey is a significantly better promoter of increases in muscle glycogen content than free form amino acids.



In conjunction with the donwregulation of genes that are encoded by type II fibers, and the up-regulation of a key transcription factor, Six1, which can reprogram adult muscle from the slow-twitch phenotype into the fast-twitch phenotype. Whey will, unlike free form amino acids eventually turn you into a fast twitch fiber powered sprint and weight lifting monster... well, almost ;-) It will obviously rather promote the development of a higher glycolytic fiber count which in turn will enable you to sprint and lift - And let's be honest, isn't that actually what you want?

If there is something free form amino acids products can do that plain whey cannot do, it's increasing the revenue of their producers. No wonder that they are touted as "almost as potent as illegal gear" and sold for prices that make me roll with the eyes. Dozens of patented "optimal" BCAA - leucine : valine : isoleucine - ratios and "superior anabolic blends" ... come on, you are beyond believing every lie you are dished up, aren't you?You never gave in to the temptation? Right you were! A recent study from Japan confirms once more: It's complete proteins trigger complete growth effects, their individual amino acids, which were used in the control arm of a recent (unfortunately) rodent study from thetheand thein Japan, on the other hand, have comparably weak effects on the post-exercise gene expression profile.But, one thing after the other, as you have already gathered from the information in the introduction, the scientists were building on their own results as well as the findings of Rowlands et al. have published inin 2011 (Rowlands. 2012). In said study, the researchers had been able to show...In contrast to their previous study, which was the basis of the discussion in an article I wrote last year (" Don't Judge a Protein by Its Amino Acid Content: 17% Higher Protein Synthesis With Whey vs. Free Form Amino Acids" | read previous article ) and where their focus was on mTOR and the fractional protein synthesis (see), the study at hand focused focused less on the net effect and more on the underlying (genomic) which explains the fact that free form amino acids suck and whey hydrolysate rules.To this ends, the researchers fed rodent diets containing either CHO + Whey or carbohydrates (CHO) that were mixed with an iso-energetic amino acid formula which had an amino acid profile that was identical to the one of the whey proteins to investigate the global effect of WPH on gene expression in skeletal muscle in comparison with an identical amino acid mixture (AAM).Their findings () are, at least for you as areader, unsurprising. Aside from the increase in insulin, a hormone lean individuals don't have to fear and probably the most potent natural anti-catabolic agent, the scientists were able to identify a dozen of other gene-factors () that may be responsible for the 16% increased fractional protein synthesis Kanda et al. observed in their latest study.The above list (cf.) leaves no doubt that the changes the researchers observed a potentially hypertrophy-health-relevant. Not all of them, were whey exclusive, but the eight specific GO terms that were significantly enriched in the set of up-regulated genes included, as the scientists point out in the discussion of their results "some key elements such as Cd24, Ccl2, Ccl7 and Cxcl1 involved in post-exercise muscle repair" (Kanda. 2014).
