'Spiking' (not Replacing) Suboptimal Amounts of #Whey With #EAAs Yields Increase in Net Protein Balance, Yet not(!) Protein Synthesis in Muscle - Acute Response Study

Written by | published on

You will probably have read about the results of this recent study from the University of Arkansas for Medical Sciences  elsewhere already - hopefully in an article that applied the same rigorous scrutiny as this one. "Wait: EAAs are better than whey?" If that's your overgeneralized and essentially wrong (there was no comparison of EAA vs. Whey, but one of EAA+whey vs. whey 😎) take-home message from the abstract of a recent study in the Journal of the International Society of Sports Nutrition  you may have recently read about on Facebook, you better read the rest of today's SuppVersity article on Park's paper, of which I would like to point out that the authors come to a very different, accurate, and more nuanced conclusion, that reads as follows: "that a composition of a balanced EAA formulation combined with whey protein is highly anabolic as compared to a whey protein-based recovery product, and that the response is dose-dependent" ( Park 2020 ...

Load Carrying Cardio Doesn't Affect Muscle Protein Flux While Intra-Workout EAA Reduces Protein Breakdown and Bumps Nitrogen Balance From Zero to Plus 50µmol/kg/h

While this picture shows loaded cardio in its most beautiful form, the study investigated loaded cardio on the treadmill and compared it (for questionable reasons) to non-loaded cardio on a stationary bike and guess what: Both burn the same amount of muscle - NET: Zero! Carrying a (heavy) load during cardio? Sounds dumb? Well, that's however, how the real world looks like. Not just soldiers who are carrying armor and a heavy backpack in the field, but also hikers will attest to the fact that doing "cardio" with a weight on your shoulders or elsewhere is more natural than running around in the park with your mobile and ear-plugs as the only load you're carrying on top of your ultra-light runners clothing. With that being said, it is actually quite astonishing that Stefan M. Pasiakos and colleagues from the  Military Nutrition Division at the US Army Research Institute of Environmental Medicine in Natick are the first to take a look at the muscle anabolic and ca...

The Muscle Building Magic of Additional(!) Leucine: 1.68g Leucine in Your Intra-Workout EAA Mixture is Good, Twice the Amount is 33% Better, Though!

Image 1:  Buying L-Leucine in bulk can save a lot of money; plus, it gives you the advantage of being able to adapt the leucine to EAA ratio, whenever you read about new study results on the SuppVersity ;-)  . I don't know if I can actually call it 'news', when I tell you that intra-workout consumption of the branched-chain amino acid leucine will help you build muscle, but I am pretty sure that you, just like me, have always been wondering whether the provision of leucine in a more 'natural' EAA composition would produce the same, or even better results . Although a number of leucine -enhanced products, i.e. EAA or BCAA products which contain more leucine than the standard 2:1:1 formulas, have been hitting the market, lately, Pasiakos et al. are the first who put the (acknowledgedly plausible) hypothesis that BCAA, or, in this case, EAA formulas with a higher than normal leucine content would elicit greater protei...
