SuppVersity - Nutrition and Exercise Science for Everyone

DMHA is rather a stim than a fat burner. But I guess it will be marketed as both. If you are following the supplement market closely, you will have seen the first products with a new stimulant on the shelves. 2-aminoisoheptane or DMHA - a supposedly worthy successor to DMAA aka "geranamine" (the stuff in the old Jacked3D) with unquestionable structural similarities to the original banned stimulant and a questionable efficacy and safety profile. With two other non-OTC agents that have been (ab)used to lose body fat for decades, namely ephedrine and clenbuterol, DMHA, which is also called octadrine and correctly labeled "2-amino-6-methylheptane" shares a history as an asthma agent (Monroe. 1947). DMHA will be banned, when this article is a SV Classic and caffeine  again the stim of choice For Caffeine, Timing Matters! 45 Min or More?

No, the study did not use a simple rope or band to restrict blood flow. Instead an automated system was used that kept the pressure at stable 100mmHg. As a SuppVersity reader  you know that blood flow restricted training is - at best - as effective as regular resistance training and can thus only be recommended as an adjunct to your regular training (efficacy unproven) or replacement for injured athletes. With a recent thesis by Daniel Cortobius and Niklas Westblad from the Swedish School of Sports and Science , the former use gets scientific backup. The aim of the bachelor students' study was to investigate how a periodized combination of classic resistance and blood flow restricted resistance exercise ( BFRE ) compares to regular training when it comes to increase in quadriceps muscle growth and strength.

With only 65mg of caffeine, an espresso provides only ~12.5% of the amount of caffeine used in the study at hand. If you've kept an eye on the latest caffeine research you may have noticed that there's an increasing number of studies that fails to find significant performance enhancing effects of caffeine during resistance training sessions (Trevino. 2015). Does this mean that caffeine, a substance that is by the way on the World Anti-Doping Agency's list of prohibited substances useless for gymrats? Certainly not. One thing most of these studies have in common is that they tested the subjects' strength or power production during short workouts. Studies that investigate the effects of caffeine in higher volume contexts, on the other hand (e.g. Lang. 2015; Thomas. 2015), confirm that caffeine is rightly the most (ab-)used ergogenic among fitness enthusiasts.

No excuse: You don't need an ex-pensive spinning bike for the workout. This is not an article for the hardcore trainees among you... unless, obviously you are a trainer or have friends and family who fall into the same "I just wannabe fit and healthy" category as the subjects of a recent study by scientists from the Manchester Metropolitan University and the Cambridge University School of Clinical Medicine (Bagley. 2016),  24 men and 17 women with a mean age of 39 (±2) years, a normal weight (BMI 24.6 +/- 0.6) and average fitness levels. In this group of "normal people", Bagley et al. aimed to examine the hypothesis that very short duration, very high-intensity sprinting exercise (on cycle ergometers) could not just improve their subjects fitness (as measured by VO2max), but also their ability to burn fat and to actually lose it.

While many US officials still believe that raw milk was a threat to public health. The internet is full of (often hilarious) health claims related to raw milk and the ill effects of pasturization. Could the study at hand provide evidence this is not complete bogus? Maybe you remember that I have been talking with my friend Carl Lanore about raw milk, pasteurization and (even worse) homogenization several times when I still had the time to do the weekly SuppVersity Science Round-Ups on SuperHumanRadio . Until now, the evidence for the often proclaimed benefits of raw milk are skinny. With the publication of a recent study by Andrew Hatchett and colleagues from the  Franklin Pierce University  this evidence the number of relevant studies has therefore increased significantly. What makes the study so relevant? Well, it was a randomized human trial in twenty healthy male collegiate sprint football (mean age 20y; height ~175cm, weight ~80kg; 1RM back squat of ~125kg; 80%...
