Are Elevated Iron and Uric Acid Levels Too Much of a Price to Pay for a Creatine-Induced 11% Performance Increase?

Video 1 (GSSI): Notre Dame 's Michael Floyd goes all out on the Wingate test ( click to watch ) I guess you could say that these are the "classic days", here at the SuppVersity , contrary to my previous post on choline , which is - judged by the few people who still use it today, an "old school supplement" (cf. " Choline: Stronger, Faster, Leaner & More Muscular, or Just Another Dumb-and-Barbell Story? ") - yesterday's post on caffeine highlighted the efficacy of a potent ergogenic aid and metabolic activator, with the effects of which most of us are so familiar that we are alway tempted to turn to useless crap like raspberry ketones , when what we are already doing is not only tried and proven, but based on respectable scientific data even more effective than the latest "innovation" from the snake oil industry. And let's be honest, haven't we all been tempted by one or another "new creatine", as well? +11% pe...

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...

Rodent Study Suggests: Selenium, Nature's Neuronal Corrosion Inhibitor Could Protect the Brains of Hard Training Athletes from Oxidative Damage.

Written by | published on
Image
Image 1: Selenium is a naturally occurring mineral involved in a host of metabolic processes. Are you a hard training athlete? A weekend warrior? Marathon runner? Or just an an average fitness-enthusiast? Yes? Did you ever think about what an exhausting workout, let alone arduous marathon running may do to your brain? No? Then it may come as a surprise to you that other than regular moderate physical exercise, which has repeatedly been shown to exert beneficial effects on mental and physical development, intense exercise precipitates oxidative stress not only in the working muscle groups, but within your whole body - including your brain, where the exercise-induced increase in free-radicals may dramatically increase lipid oxidation ( Goldfarb.1996 ; Kanter. 1998 ). Based on observations with other antioxidants and the well-established involvement of selenium in the activation of the master-antioxidant glutathion , researchers from the Selcuk University in Konya, Turke...

Vitamin E Exerts Positive Effects on Various Health Markers in Recreational Trainees

Written by | published on
A study from scientists from the Azad University in Iran ( Naghizade. 2010 ) shows that supplementation with 500mg vitamin E (~750IU) over a period of 8 weeks improved malondialdehyde (MAD, p<0.02) , creatine phosphate (CP, p<0.04), total antioxidant capacity (TAC, p<0.03), LDL (p<0.03) and Vo2max (p<0.03) over placebo values in moderately aerobically trained individuals: In summery performing moderate aerobic exercise (HRmax 60-65%) with consumption Vitamin E may decrease membrane damage and lipid peroxidation, and cardiovascular risk factors. These results stand in line with several other papers that have been released within the last months. Many of these found positive effects of vitamin E on moderately (mostly aerobically) training trainees, like the ones in this studies. If, however, the workloads increase way beyond the 3x45min (per week) the male subjects of this study spent in the gym, the results become equivocal and some studies even suggest that additional ...

Omega-3 Fatty Acids PRO(!)-Inflammatory in Athletes

Written by | published on
Although I am aware of the magnitude of studies providing evidence for the positive effects of omega-3 fatty acids in general and EPA and DHA, in particular. I think you should be aware that research on its effects in athletes (as the general effect of anti-oxidants on healthy people) are less unequivocal than those on positive effects on your average pre-diabetic fatso. In a very recent study, scientists from the Unité de Formation en Sciences et Techniques des Activités Physiques et Sportives in France ( Filaire. 2010 ) found that judo athletes who took a standardized omega-3 supplement (600 mg EPA and 400 mg DHA) for 6 weeks had significantly increased stress markers compared to placebo: Significant interaction effects between supplementation and time on resting MDA [malondyaldehide] concentrations and Rmax were found (p = .03 and p = .04, respectively), with elevated values in the n-3 LCPUFA group after supplementation and no change in the placebo group's levels. The ...

Zinc Supplementation Helps Prepubescent Children with Metabolic Syndrome

Written by | published on
Zinc ain't for bodybuilders, only! In a double blind placebo controlled crossover study Kelishadi et al. ( Kelishadi. 2010 ) supplemented prepubescent obese children with metabolic syndrome with 20mg of elemental zinc to evaluate the effects of zinc supplementation on anthropometric measures and blood pressure, fasting plasma glucose, lipid profile, insulin, apolipoproteins A-1 (ApoA-I) and B, high-sensitivity C-reactive protein (hs-CRP), leptin, oxidized low-density lipoprotein (ox-LDL), and malondialdehyde: Irrespective of the order of receiving zinc and placebo, in both groups, significant decrease was documented for Apo B/ApoA-I ratio, ox-LDL, leptin and malondialdehyde, total and LDL-cholesterol after receiving zinc without significant change after receiving placebo. In groups, hs-CRP and markers of insulin resistance decreased significantly after receiving zinc, but increased after receiving placebo. In both groups, the mean body mass index (BMI) Z-score remain...

Rat Study Suggests Increased Selenium Requirements in Athletes

Written by | published on
Calcium and magnesium , zinc and maybe chromium those are the top sellers among minerals and trace-minerals. Others, such as selenium are likely to be overlooked by the average fitness maniac, who says to him/herself "Selenium? Its in my multi, anyway!" Yet, a recent study published in Biological Trace Element Research ( Akil. 2010 ) reports well measurable effects of selenium supplementation to rats on an exhaustive exercise regimen. The scientists measured the impact of acute swimming exercise on erythrocyte-reduced glutathione ( GSH ), serum glutathione peroxidase ( GPx ) and superoxide dismutase ( SOD ), and plasma malondialdehyde ( MDA ) and lactate levels of the animals and found: Results of the study indicate that the increase in free radical production and lactate levels due to acute swimming exercise in rats might be offset by selenium supplementation . Selenium supplementation may be important in that it supports the an...
