Intra-Workout Supplementation: Increased Carbohydrate Oxidation with L-Arginine, Lower Fat Oxidation with Glucose & Lowest Rate of Perceived Exertion with Plain Water

Written by | published on

Image 1: This bird certainly knows about the importance of adequate hydration ;-) Have you been at the gym today? If so, what kind of beverage have you been sipping in the rest-periods between your sets , your sprints or during your regenerative (not fat burning ;-) "classic" cardio exercise? Was it Funky XYZ the latest and greatest intra-workout product on the market? If so, you better check out its ingredients, who knows maybe the "latest and greatest" turns out to be quite counterproductive towards the goals you have been setting after reading one of the last two installments of the Intermittent Thoughts ? Let's assume you are the "Peter Griffin"-type of chubby - in that case, I hope that your Funky XYZ did not contain glucose, maltodextrin, waxy maize, or any other of the sugars of which the supp companies are going to tell you that they "superior" to the white poison your granny uses in her delicious muffins. Why? Well, according...

An Old Dog Learns New Tricks: "Fatloss Fat" Tetradecylthioacetic Acid (TTA) Cardioprotective in Diabetic Rats

Do you remember the acronym TTA? Tetradecylthioacetic Acid ? No. Well, I guess then you were not into fat burners in the early 2000s. TTA , a thia-fatty acid, was all the rage back in the day: Supplement producers claimed it would literally melt fat away and it actually turned out that some users had outstanding results megadosing respective supplements. Others, however, got bloated and/or started cramping . In view of these nasty side effects, most companies decided to reformulate their products and - with the exception of a few so-called "non-thermogenic" fat burners - TTA has almost disappeared from the market. An international team of scientists from Norway and Canada ( Khalid. 2011 ) has now discovered that the artificial fatty acid tetradecylthioacetic acid, which was originally intended as a drug for the treatment of the metabolic syndrome, might have the potential to protect type II diabetics from heart attacks. In a previous study ( Hafstad. 2009 ) the scientist...

Want to Burn More Fat During Your Cardio Training? Eat Low Carb Before Workout!

Written by | published on
Modulation of substrate utilization is the key to effective weight loss. For years we have been told that "training in the zone" (referring to a specific heart rate) would do the trick - recent research does yet suggest otherwise: High Intensity Interval Training (HIIT) has been shown to be at least as effective in burning off unwanted body fat, as the longstanding "gold standard", Low Intensity Steady State (LISS) in the "fat burning zone". Researchers from the Department of Exercise Science and Sports Studies at Springfield College, Springfield, MA, USA, have now found that apart from the type of exercise you chose to perform, the nutrition, especially in the hours before working out, determines whether you will predominantly burn fat or carbs to sustain the workout. In their study ( Gregory. 2011 ), Gregory et al. compared the metabolic responses of a group of 8 "active, pre-menopausal" women to a 30 minute exercise regimen performed afte...

L-Carnitine Works! At Least if it's L-Carnitine L-Tartrate.

Written by | published on
Initially, carnitine was considered the super-supplement for both, the athlete seeking the ergogenic edge, as well as for the obese trying to shed unhealthy body fat. Surprisingly, however, study after study showed no to little effect on exercise performance and/or fat loss. Ultimately, it became clear that, even at very high doses, only very little of the orally delivered l-carnitine actually makes it to the muscle. Consequently, its effects on performance and body composition where negligible. Now, a very recent study by Wall et. al. ( Wall. 2011 ) found that adding a transporter, in this case l-tartrate , to the molecule does not only help to increase muscle carnitine levels, it eventually produces exactly those effects on exercise performance and substrate metabolism one would have expected from l-carnitine supplementation in the first place. The scientists had their 14 healthy male volunteers ingest either 80 g of CHO (Control) or 2 g of L-carnitine L-tartrate and ...
