SuppVersity - Nutrition and Exercise Science for Everyone

Betaine or citrulline? Choose now. Article #2 of this series is a bit more "anabolic" than the first serving . Based on the abstracts to studies by Hudson et al, Cicholski et al and Hwang et al it explores the effects of betaine supplementation on the adaptational response to resistance training in female rookies and the longitudinal effect of the NOx-boosting combination of citrulline + glutathione (see previous article ) on the body composition of resistance-trained male subjects. As usual, the discussion of the studies is infused with plenty of information from previous research... and for those who want nothing but the gist, there are the practical implications in the bottom line.

Who would have thought that barefoot running triggers instant improvements in running economy? With the release of ahead of print articles for the next issue of the Journal of Strength and Conditioning Research , it is high time for yet another research update; an update with research on the effect of vitamin d supplementation on training adaptation in well trained soccer players, acute citrullin malate supplementation (10 grams 60 minutes before a workout) and high-intensity cycling performance, as well as information about the ability of barefoot running to reduce oxygen cost and improve running economy in female distance runners who have never run barefoot before.

"Shed the fat, keep the muscle!" That's a promise you will find not literally, but analogously in every ad for BCAAs, but do they actually do that? Help you shed fat and retain muscle? Scientific prove to support this claim is, as of yet, missing. With BCAAs it is just as it is with 99.9% of the supplements: Ads and product labels are full of scientifically unproven claims. One of these unproven claims is that the consumption of branched-chain amino acids would protect you from losing muscle while you're dieting ... the problem with this notion is - as sound as it may seem in view of the mTOR promoting effects of leucine, there's no study which would prove that guzzling BCAAs all day will in promote fat and blunt lean mass losses when you're cutting.... or I should say "as of now, there was no study...", right? After all, there's this new study by Dudgeon et al.'s the abstract of which tells us that "BCAA supplementation in trained i...

Synephrine, arginine, citrulline - Which pre-workout ensures that you're "on fire"? As I pointed out previously , my initial idea to cherry pick only the most interesting study results that were presented in form of of poster presentations at the Twelfth International Society of Sports Nutrition (ISSN) Conference and Expo in 2015 didn't work out. The number of interesting studies is is simply too much for a single SuppVersity  article to discuss them all. Accordingly, I am now posting the 2nd serving of what is going to be a multi-part series of articles with brief discussions of the most significant results of the >20 studies and short references to those that didn't make the SuppVersity  cut in this, previous and future installments of this series for one reason or another.

If you belong to the people who simply cannot stay away from HFCS foods and beverages, you may be happy to hear that the equivalent of as little as 10g citrulline or NEAAs in your diet may do much more than "just" fully prevent its negative effects on your liver. You will probably remember from previous articles I wrote that NAFLD, or rather the development of non-alcoholic fatty liver disease, is one of the earliest markers of metabolic syndrome and beginning type II diabetes. In the Western obesity societies in North America and Europe, NAFLD is among the most common causes of chronic liver disease and its prevalence is increasing rampantly (Marchesini. 2001). In spite of the fact that its development is most strongly linked to the consumption of a generally unhealthy, energetically dense diet, there are several lines of evidence which suggest that the ingestion of exorbitant amounts of fast-digesting fructose from high fructose corn syrup (HFCS) sweetened beverages ...
