Sodium-/Potassium-Bicarbonate (+Mg, +Ca) Supplement ➡ Improved 6x30m Sprint Time, Lactate, Magnesium & More | Plus: Enterically Coated NaHCO3 Tablets - Where are They?

Written by | published on
Image
The stack (ingredients on the right) was ingested twice daily. It has been a while since the last study on sodium bicarbonate's usefulness has found its way to the SuppVersity. And, technically speaking, the latest RCT by scientists from the  Department of Sports Training at the Jerzy Kukuczka Academy of Physical Education in Katowice, Poland, and colleagues from the Miller School of Medicine , at the University of Miami is a "bicar-bonate", but not a "sodium bicarbonate" study. How's that? Well, the scientists did exactly what some of you have already suggested: They combined sodium-  and potassium-bicarbonate (the authors write di-carbonate, which is obviously the same) at a dosage of 3g, each, to achieve a balance between the two macro-minerals and topped the bicarbonates up with 1000 mg (600 mg + 400 mg) calcium phosphate and calcium citrate , 1000 mg potassium citrate , and 1000 mg magnesium citrate. Mineral water will contain some K and M...

Research Update: 5000 IU/day Vitamin D, 12g/day Citrulline Malate or Barefoot Running What's the Most Ergogenic?

Who would have thought that barefoot running triggers instant improvements in running economy? With the release of ahead of print articles for the next issue of the Journal of Strength and Conditioning Research , it is high time for yet another research update; an update with research on the effect of vitamin d supplementation on training adaptation in well trained soccer players, acute citrullin malate supplementation (10 grams 60 minutes before a workout) and high-intensity cycling performance, as well as information about the ability of barefoot running to reduce oxygen cost and improve running economy in female distance runners who have never run barefoot before.

New Insights into the Role of Vitamin D in Athletes: Soccer Players Offer Ideal Study Subjects - Vitamin D (25-OHD) Predicts Performance, Training Season Predicts Vitamin D

Written by | published on
Image
Not the ideal soccer weather. If you put faith in the authors' interpretation of the results, soccer is a game that must be played in the sun. Why? Well, to maximize the vitamin D production ;-) It has been a while since I have seen a study on vitamin D that provides new-worthy results beyond the obvious "vitamin D supplements are useless in men and women with normal 25-OHD levels". The study I am about to talk about today was conducted by researchers from the University of Crete . The subjects were sixty seven Caucasian professional male soccer players, members of two Greek Super League Teams (n = 45) and one Football League Team (n = 22). The goal was to (a) examine the potential relationship between vitamin D levels and muscle strength, maximal oxygen consumption (VO2max), 10 and, 20 meters sprint performance in two different occasions, prior to the beginning and at the end of the off-season soccer period; and (b) to examine the vitamin D response to the reduced e...

Is Hydrolized Whey, the New Way to Go? 12 Week Human Study Suggests: Yes, If Your Goal is to Ward Off Oxidative Damage. No, If You Want to Build Muscle & Lose Fat

Written by | published on

The typical soccer player is no longer a stick on muscular legs, these days. The sport has changed and so have the physiques of the players. I guess ever since I published the article "The Glucose Repartioning Effects of Isoleucine: Falsely Underappreciated BCAA and Its Dipeptides Maximize GLUT-4 Expression and Ramp Up Muscular Glucose Uptake" ( read it ) that discussed the beneficial effect of the small isoleucine peptides in hydrolized whey on glucose metabolism, some of you may have been wondering, whether theh previously sneered at even more insulinogenic fast-digesting, bad-tasting, highly-processed whey protein hydrolysates (WPHs) may not be an alternative, if not the better alternative to whey concentrates or isolates. Personally, I have always favored the "whole" over its individual parts, but the evidence that there is something special about WPH is accumulating. "So what kind of new evidence is accumulating here? " That being said, the...

80g Glycerol + 2L Water Decreases Body Weight in Athletes & Increases Overall Performance in Sedentary Subjects

Written by | published on

If it does not make you as swole as the colorful ad promised it must not be working, right? The jury was not even any longer "out there" for glycerol, but a recent study makes you rethink, whether you just have to look in the right place to see the benefits. Another of the "odd" Thursdays without an update from "Your's Truly" Adelfo Cerame . And since there is holiday today, over here, I even thought there would not be a SuppVersity Science Round Up today. But hey, you are lucky you (and Carl) got to work, so you can tune in live at 1PM EST, or even better, start listening live at 1PM in order not to miss the Strength and Hypertrophy Round Table ! As far the  topics for today's installment of the SuppVersity Science Round Up are concerned, you are actually only a couple of lines away from reading about one that's on the list:  The effects of glycerol on exercise performance. I don't have to tell you though that this is not everyth...

6mg Melatonin 30min Before HIT Will Increase Fatty Acid Oxidation, Boost Your Antioxidant Capacity, Reduce MDA Levels and Modulate Your Immune Response

Image 1: Other than you may have expected, this is exactly not what happened when the soccer players took 6mg of melatonin before their workouts. The blogpost on melatonin's anti-Alzheimer's + anti-obesity effects from last week caused quite a stir, both in the comment area, here at the SuppVersity, as well as on facebook. Even friends in the gym came up with questions. Therefore, I suppose that you won't mind, if I re-address the topic today. This time, however, with data from a human study , of which I bet that it will catch your interest... after all, the study, which has been published ahead of print two days before Christmas could hold the key to winning the FIFA World Cup 2014 ;-) Melatonin makes you sleepy? I don't think so! I guess, even after last week's news , most of you will still think of melatonin as the "sleep hormone". At least those of you who follow my recommendation to make sure that they get their daily dose of SuppVersity new...

2g Arginine /Day Induce Vasolidation and Increase VO2Max in Male Soccer Players

Written by | published on
Regular readers of the SuppVersity will know that - despite the recent bashing of arginine by the some supplement producers - I like this universal amino acid AND studies supporting the notion of athletes being able to benefit from arginine supplementation keep coming. The most recent one was done by Kamil et al. ( Kamil. 2010 ) and investigated the effect of 2g pure l-arginine on vasolidation and VO2Max in soccer players. Their findings were as follows: Oral supplementation of L-arginine significantly (p<0.01) decreased blood pressure indices and increased VO 2 max (p<0.01), blood flow (p<0.05), femoral artery diameter (p<0.05) and urea levels (p<0.05). There was no change in blood lipid levels (p<0.05). No significant changes were noted in the placebo and control groups. The increase in VO2Max, as shown in Table 1 was relatively low, though. Yet, it's statistical significance stands out of question. L-Arginine Placebo Control ...
