Protein Wheysting?! No Significant Increase in PWO Protein Synthesis W/ 40g vs. 20g Whey, But 100% Higher Insulin, 340% More Urea & 52x Higher Oxidative Amino Acid "Loss"

No, I don't think the results would have been different, if the subjects had been young women. For older guys and gals, on the other hand, I am not 100% sure. It has been a while since we've been taking a look at one of the two or three dozen "whey increases muscle protein synthesis" studies and, officially, we would have to wait not just for Santa, but actually until January 2014 to take a glimpse at the results Oliver C Witard, Sarah R Jackman, Leigh Breen, Kenneth Smith, Anna Selby, and Kevin D Tipton present in their soon-to-be-published paper in the journal of the American Society for Nutrition (Witard. 2014). The intention of the researchers was (yet again) to "characterize the dose-response relation of postabsorptive rates of myofibrillar MPS to increasing amounts of whey protein at rest and after exercise in resistance-trained, young men", (Witard. 2014). This is nothing new, but still right up the average SuppVersity reader's alley, I sup...

45x More Testosterone Yet Identical Increase in Protein Synthesis: MPS Response to Exercise + 25g Whey in Men vs. Women Challenges Common Wisdom About Androgens

Image 1: Is it not testosterone that makes the difference? It is an open secret that women are having a much harder time building muscle than men, and it is another instance of (bro-)scientific wisdom that the obvious lack of testosterone in female strength athletes would be the underlying reason. Right from Stuart M. Phillips lab at the Department of Kinesiology of the McMaster University in Hamilton, Ontario, Canada, comes a new study ( West. 2012 ) which puts yet another questionmark behind the anabolic prowess of testosterone (if you still believe that a transient increase in testosterone will help you build muscle, I suggest you read up on " The Big T " in the Intermittent Thoughts on Building Muscle ). Women are different, but it's not about protein synthesis In the recently conducted trial Daniel W.D. West, who has also been the lead author of the "Never Sip Your Whey" study , I covered back in November 2011, undertook another attempt to identif...

Time Under Tension (TUT) Another Under-Appreciated Determinant of the Protein Synthetic Response to Exercise?

Image
Image 1: Is it really time to buy some revolutionary new exercise equipment to time your time under tension? Or should you keep pumping away like there was no tomorrow? If you have been following the SuppVersity news for some time now, you know that I am a "fan" of the research Stuart Phillips and his colleagues at the Department of Kinesiology at McMaster University in Hamilton, Ontario, are doing. Before I get to some details on their latest coup, I must yet express some concerns about Phillips' focus on immediate changes protein synthesis. Yes, amino acid ingestion and particularly leucine increase protein synthesis , yes, bolus ingestion of whey protein increases protein synthesis over sipping and yes, training with low loads (30%) and slow reps, as in the study at hand, increases protein synthesis ,... but hey. Do you really give a damn about protein synthesis? No, you don't. Either you want to gain muscle or you want to get stronger and exactly here I am m...
