Green Tea Extracts, Athletes and a Preliminary Answer to the Question: "Are Anti-Oxidants For Athletes Not?" No True Benefits or Negative Effects of 1g GTE in Sprinters

Written by | published on
Image
The supplement that was used in the study at hand was a commercially available product from Olimp Labs, a Polish producer of bodybuilding and fitness supplements. Before I even go into more detail, I would like to point out that the study today's SuppVersity article will talk about is not able to answer the question whether anti-oxidants are for athletes once and for all. Why? Well, the subjects in the recently conducted experiment by Ewa Jówko, Barbara Długołecka, Beata Makaruk and Igor Cieslinski were sprinters from a University Sports Club, and they received a green tea supplement - so who can guarantee that a bodybuilder taking vitamin C would not have a totally different reaction to a totally different anti-oxidant? No one can and that's why I'd like to ask you to go back to some of the previous articles on that matter and remind yourself that there is evidence that the provision of significant amounts of supplemental antioxidant can blunt the beneficial adapti...

Eccentric Exercise IGF1 & Athlete's Heart; Long or Short Intervals, Both Improve Arterial Stiffness. Plus: Exercise Heals Wounds & Makes You Rust Proof Within One Year!

Written by | published on

Controlled exhaustion = positive adaptation; continuous exhaustion = wear and tear = one out of 57,002 who suffer from cardiac arrest during a marathon (data based on Webner. 2012) As announced on Saturday, already this is a "special edition" of the On Short Notice series, focusing exclusively on exercise related studies. With two studies on heart health ,  one on wound healing and the last one on the  bullet proof endogenous anti-oxidant system of trained athletes,  this installment of the " Exercise News Roundup " and two studies on different HIIT, it does however have both a health , as well as a HIIT focus. I know that does not sound as sexy as being big and buffed, but what's the use of that if you don't fit the coffin, you're about to need, when your looks are more important to you than your health? IGF-Response to exercise implicated in "athletes heart" A group of polish researchers describes in their latest paper that...

3.2g of Beta Alanine Reduce Rate of Perceived Exertion, Increase Time to Exhaustion and Ventilatory Threshold. Vegetarians, Older People and Diabetics May Benefit Most.

Image 1: If you are into running, ladies, beta alanine is for you ;-) Those of you who make sure that they are getting their highly educative daily dose of the SuppVersity *rofl* will be aware that today's blogpost is, once again, dealing with beta alanine. Contrary to yesterday's post , which dealt with its pharmacokinetics, we are today going to have another look at what kind of real world performance outcomes the average (female!) physical culturist can expect from taking at least 3.2g of the beta amino acid per day - a dosage that has been shown in previous studies to increase intra-muscular carnosine levels by 27–39% in fast- and slow-twitch muscle fibers, respectively ( Baguet. 2009 ). And though I do not want to spoil things, I can already tell you that the results make it quite clear why beta alanine is not the next creatine . Somehow ergogenic, yet not really antioxidant For the study that was conducted at the Applied Physiology Laboratory at the University ...

Update on Antioxidants & Exercise - Neither Vitamin C Nor E Have ANY Effect on the Response to Intense Exercise.

Written by | published on

Image 1: If you add some reactive oxygen species to this mitochondrium, this will trigger beneficial, (mito-)hormetic adaptations, that could be blunted by too many antioxidants. As a diligent reader of the SuppVersity, you have probably been following my posts on antioxidants and their potentially negative effect on the adaptive (hormetic) response to the exercise induced formation of reactive oxygen specimen. Although, I still believe that the theory may have its merit - especially in metabolically deranged people, where the exercise induced ROS formation would initially have to overcome the low-grade chronic "background" stress - it appears that for healthy people, and "moderately trained young men" on an intense exercise protocol, in particular, the ingestion of reasonable amounts (<1g of vitamin C and <400IU of vitamin E) does not pose a problem . At least this is what the results of two relatively recent studies by scientists from Washington Schoo...

Transfats the Last Bastion of the "Bad Fats"!? Two New Studies Shed Some Light onto Their Impact on Your Health.

Written by | published on

Image 1: The Meet the Fats campaign is part of the stultification... ah I mean educational program of the American Heart Association Meanwhile, even mainstream dietitians are beginning to understand that fats, which have been a, if not THE staple energy source in human history are not the bad boys the anti-fat hysteria of the 1980s would make us believe. Even the American Heart Association begins to advocate the use of "healthy fats" as part of a "heart healthy diet" - unfortunately, the AHA guys still lump Sat (that is the obese guy in the left) Trans (that is the sleazy guy in green) together , although the evidence against poor Sat (who obviously represents all saturated fats) is less conclusive than that against Poly, his money-grubbing sister who would do everything for her sponsors from the corn-industry... well, be that as it may, today's charge is against Trans who is accused of arson, or whole body inflammation, to be precise ;-) New evidence a...

2g Vitamin C Ameliorate Low Testosterone Levels and Sexual Dysfunction in Diabetic Rats. Usefulness in Normoglycemic Individuals Still Questionable.

Written by | published on

Illustration 1: In view of the increase in renal vitamin C clearance with higher plasma levels ( Friedmann. 1940 ), it may be sensible to use a time-released vitamin C formula , or, even better, eat a serving of veggies or fruits that are high in vitamin C multiple times a day Yes, I know, supplemental vitamin C does not ward off the common cold... the same applies for taking super high doses of vitamin C as antioxidant buffers before or around workouts. In fact, studies have shown that the antioxidant overkill of a combination of vitamin C and other powerful antioxidants could negate the beneficial effects exercise has on human blood glucose management. Now, a group of Brazilian scientists has published a rodent study that seems to suggest that in the absence of exercise the addition of 2g (human equivalent for 80kg male) of vitamin C to your diet could partially restore sexually function and increase testosterone levels in diabetic pa...

DHEA Protects Rat Livers on a High Fat Diet

Written by | published on
Image
First of all, rats are not a particularly good model for DHEA metabolism in human beings. Nevertheless, the results of a study by Magyar et al. ( Magyar. 2010 ) would warrant further investigations into the effectiveness of high dose DHEA supplementation on total scavenger capacity and liver fat content in men. In the course of a 28 day intervention the scientists fed rats on either a normal or a high fat diet and supplemented their drinking water with no DHEA (Control), 400µg DHEA (DHEA) and 150µg DHEA-Sulfate (DHEA-S). Table 1: Fresh frozen liver fat content, SOD, catalase and GST activity results on Day 28 As the figures in Table 1 indicate both, DHEA and DHEA-S were able to reduce the negative effect of the high fat diet on liver fat content and oxidant status (as measured by SOD-, Catalase and GST activity). This is an interesting result, of which the scientists write: Our results support the hypothesis that DHEA and DHEAS supplementation can improve the antioxidant status ...
