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

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...

Protein-Timing & Fasting: Fasted Sprints & the Remarkable Muscle↑, Fat↓ Effect of Timing Whey With vs. Between Meals

Written by | published on

Not sure what would happen to your sprints if you have whey before HITing it... While more and more scientists and "evidence-based" trainers and fitness gurus, alike, keep repeating that "protein timing" - as heavily and feverishly as it is often debated on Facebook and elsewhere on the interwebs - is significantly less important than some gymrats still tend to believe ( Schoenfeld 2013 ). The question "When do I take my whey shake?" is still a topic worth discussing. In particular, if an interesting new study - a systematic review, to be precise - seems to suggest that protein timing does, at least in protein supplementation studies, matter... and what's most exciting, it seems to matter for the one outcome of physical exercise and dietary discipline many gymrats consider the #1 on their priority list: improvements in  body composition ... or, as many call it, "getting ripped and jacked" ;-) Learn more about building muscle and stre...

Healthier, Fitter & Leaner After 12-Day McDonalds Challenge Thanks to HIIT? Plus: TRX®, Fitness ↗ Fatness ↘ in Women

Short news: Sprinting & TRX  "Have you already burned off that burger you had for lunch today?" If that's a question you're asking yourself regularly, you are at a high risk of misinterpreting a recent study by Christian Duval et al. (2017) as a license to eat how much you want, whatever you want, whenever you want. Unfortunately, a 12-week study in which young, healthy subjects were allowed to consume only three more or less energy-adequate meals is not representative of the futile "if you eat more/worse, just exercise more"-approach to diet and exercise. Apropos exercise, if you're still looking for the right exercise to get or stay fit and healthy, TRX training, the suspension training bodyweight exercise that has purportedly been developed by/for US Navy Seals seems to actually live up to some of its promises of developing strength, balance, flexibility and core stability - overall fitness (VO2max) improvements are yet probably its greatest...

The first December 2016 research update with studies that are relevant for both, women and men. I mean, who wouldn't want to get sign. more muscular in hours? I guess those who know that this is just an often overlooked measuring error. Have you ever wondered about the accuracy of your DXA data? It's supposed to be "the gold standard", but you've learned only recently in the SuppVersity  Facebook News  that this is only the case if you measure at the same time of the day, identical hydration and - as a more recent study shows - even identical glycogen stores. What? Yes, that's right! You can make DXA-confirmed 3% gains in lean mass within hours. Simply by glycogen loading. You're not interested in body fat data? Well, this is your lucky day. Today's installment of the short news will also discuss the latest study on the interaction between oral contraceptive and the adaptive response to exercise (Schaumberg. 2016). Looking for more cutting edge...

The Bitter Taste that Gets You Going: Quinine Mouthrinse Provides Instant 4% Power Boost During 30s All-Out Sprint

Written by | published on

Getting ready for an all-out sprint? A bitter mouth rinse W/ quinine will provide instant power boost of 4% in ‘ur 30s cycle sprint more than a sweet mouth rinse could do . If you're a powerlifter, the idea that rinsing your mouth with a bitter substance can improve your performance is probably no news for you... even though, powerlifters smell, not taste ammonia, smelling and tasting are, after all, more or less two sides of the same coin (Rozin. 1982). Against that background and in view of the similar brain activation patterns scientists have observed in response to bitter and sweet taste perception, it appears only logical for Sharon Gam et al. to speculate in a 2014 paper, which is still worth its own SuppVersity article (!), that rinsing w/ quinine, a distinctly bitter substance, could produce the same or at least similar power increments as sweet substances. For longer sprints bicarbonate may be the more effective choice The Hazards of Acidosis Build Bigger L...
