Coffee Never Disappoints: Myth that Habitual Consumption Reduces Caffeine's Acute Ergogenic Effects... Dispelled!?

Image
I must remind you, though, that performance benefits in one domain don't always transfer to another one. In other words: While the study seems to dispell the myth for classic endurance training, effects on activities where CNS activity is more important, like lifting, for example, may still be impaired w/ habitual intake. I guess even I have to confess that I may have propagated the myth that habitual caffeine consumers would not benefit to the same extent from pre-workout caffeine supplementation as caffeine naive individuals. What I know for a fact, though, is that I also mentioned in previous caffeine/coffee articles that the "jitters" caffeine-naive individuals may experience could ruin all the benefits of the often-heard of extra effect on the central nervous system (CNS). As de Souza Gonçalves et al. (2017) point out in their recent study, previous experimental efforts to determine "the relationship between habitual intake of caffeine and the effect of ca...

Meta-Analysis: Could Energy Drinks be All About Taurine? Taurine, not Caffeine Predicts Performance Enhancement

Image
While almost all energy drinks appear to have it, the evidence that taurine adds to the effects of caffeine has hitherto been unconvincing. Does this change with the latest study by a group of researchers from Brazil and Spain? Energy drinks (ED) are all about caffeine, right? I have to admit. If you had asked me before I've read the latest study from the Londrina State University in Brazil and the Camilo José Cela University in Spain, I would have answered this question in the affirmative. I mean, come on... the strange add-ons the producers mix into their drinks have but one purpose: distinguish drink X from drink Y and, even more importantly, the healthier competition of plain coffee. The fact that Souza, et al. observed in their latest meta-analysis that "a signifcant association between taurine dosage (mg) and performance (slope = 0.0001; p = 0.04), but not between caffeine dosage (mg) and performance (slope = 0.0009; p = 0.21)," caught my attention. You can...

DMAA / OxyElitePro - The Good, the Bad and the Downright Ugly - More Powerful (+180% Perf.) Than You'd Think, but ...

Image
Back in the day, when the original Oxy-ELITE Pro was pulled from the market, people paid crazy amounts of money for the bottles that were left on Ebay - a big mistake! Not because it would fry your liver, but rather because it's ' stim ' effects will - just as those of other DMAA products - turn against you, w/ chronic use.  You may (rightly) be asking yourselves, why I am addressing an (albeit famous) supplement that is no longer on the market in 2016 blog post. Well, the answer is simple. I still see people whining about how "awesome" this product was all over the web. People who wish that DMAA and OxyElitePro would come back and people who would be willing to spend at least 5x the original price for the few (long expired) bottles that appear to be traded on the black market. It's those people I want to advice: Even if you ascribe the liver damage as the result of stupid overdosing and acknowledge that other products appear to be far worse (García-Cort...

Non-Stimulant, Non-Effective?! Can Non-Stimulant Dietary Herbal Supplements Boost Your Resting Metabolic Rate?

Image
There are two types of alleged fat burners: Type I are the stimulants with proven beneficial effects on you resting metabolic rate and beneficial "side effects" on energy levels and (reduced) appetite. Type II are non-stimulant "fat burners". Two of those have been tested in a recent study ... learn what the study says. Amanda J. Salacinski, Steven M. Howell, Danielle L. Hill, & Steven M. Mauk, researchers from the Department of Kinesiology and Physical Education  at the Nothern Illinois University didn't miss that weight loss supplements are becoming increasingly popular - even in people with with chronic diseases (usually as a consequence of obesity). Even in healthy individuals, the list of side effects that have been reported for the various fat burners is long (Salacinski et al. highlight G.I. distress, and liver inflammation, which may accompany weight loss resulting from chronic supplementa-tion, in particular)... and while it is long, very lon...
