Infinit Nutrition Adds Five Flavors, More Tutorials & Updated Website

infinit-nutrition-new-flavorsInfinit Nutrition, which offers customized sports and recovery drinks alongside stock retail packaged products, has just added five new flavors.

Joining the original Orange, Lemon-Lime and Fruit Punch are Pink lemonade, Grape, Salted Caramel, Mocha and Chocolate. We’re thinking a few of those are better suited to recovery formulas, but to each their own. Their website has been updated to ease the customization process, just slide each ingredient type (protein, amino acids, carbs, calories, flavor intensity, caffeine and electrolytes) to your liking and they’ll blend and package it just for you. Not sure what your body needs? Just check out their updated video library for more information and education.

Curious about how it all works and what’s available? Check our reviews here and here. Their preformulated, ready-to-go products are available in the new flavors, too, you just need to click “Customize Now” rather than “Add to Cart” and change the flavor selection.

Ted King Launches UnTapped, Packages Organic Maple Syrup in Sports Friendly Package

20140717-222403-80643234.jpgA few weeks ago we ran a series of articles on the use of gels by performance athletes, which generated heated arguments in the comments section.

Whichever side of that aisle you stand on, I think it can generally be agreed on that maple syrup (the real stuff, not Aunt Jemima’s) is delicious.

Like honey, the good stuff has a proven track record on pancakes, and in the pro peloton. Famous American cyclist Ted King has been using the all natural performance enhancer for years, and has now partnered with Slopeside Syrup to bring it’s benefits to the masses.

The delicious energy booster treat is “produced simply by boiling maple sap directly from a maple tree. Because it’s unprocessed, it’s rich in vital minerals such an manganese, iron, calcium, and zinc. It also has essential vitamins, is high in critical amino acids, and is bursting with antioxidants required for proper recovery.”

To get the project off the ground, Ted and his partners have turned to Indiegogo. They’ve currently reached roughly half of their $30,000 goal. Want to try the all natural Vermont made recovery syrup (or simply want to keep a few packets around just in case of a breakfast emergency)? You can back the project here for as little as $25

Physiology and Nutrition: Dealing with the Heat


Summer’s hot. And as you get hot, your performance drops. Here’s the how and why, and how to keep your cool.

Human temperature regulation processes maintain a core body temperature over a very narrow functional range despite elevated metabolic rates and exposure to very hot environments. During submaximal exercise, we can limit the effects of the increased heat production through sweating and evaporative cooling. But as intensity climbs, our ability to offload heat becomes limited; in conjunction with a hot/humid environment; we are most likely going to experience hyperthermia. Technically, heat stress and hyperthermia are the overarching umbrella terms for heat illness (heat exhaustion, heat stroke), and are identified as an elevated body temperature due to failed thermoregulation that occurs when the body produces or absorbs more heat than it can dissipate.

During exercise in the heat, the most significant physiological burden is supporting blood flow to the skin: high skin blood flow is needed for heat dissipation. (The average blood volume of an adult male is ~5 liters, and the average female ~4.4 liters, not much to go around!). We often think of a high core temperature as being the limiting factor for performance; eg the “critical core temperature”, but it is more the temperature of the skin that affects aerobic performance. Skin temperature is highly influenced by the ambient temperature and humidity, whereas the core temperature is influenced by the intensity of the exercise (which is partially why a power decline is seen with elevated internal temperatures). Warmer skin induces a greater amount of skin blood flow, decreasing blood volume available for circulation. For example, with a sustained elevated core temperature, an increase in skin temperature will have a concomitant increase in heart rate but the reverse is also true- cooling the skin even with a sustained elevated core temperature will reduce heart rate due to more blood shunting back into circulation(1).


GU Brew Sports Drink Gets Nekkid & Fruity


Last summer, GU reformulated their Brew sports drink to have a bit lighter carbohydrate load and improved electrolyte profile. Now, for summer 2014, they’re adding four new flavors, including the unflavor Tastefully Nude. It’s joined by Lemon Tea, Watermelon and Blueberry Pomegranate.

The new formulation has 70 calories and 19 grams of carbohydrates per serving, with 250mg of sodium and 30mg of potassium in all but the Blueberry Pomegranate, which bumps up to 500mg of sodium. Carbs come from maltodextrin and fructose in a 50-50 balance.

The entire line uses a lighter flavor profile since everything tastes sweeter and stronger during hard exercise, and the new options help prevent “flavor fatigue”. Brew comes in 24-serving canisters ($20) and single-serve packets ($1.50).

Must Watch: Forget Gels, Corn Dogs For the Win

Bikerumor reader Peter Koch found inspiration in the video above, which lovingly shows Team Sky’s rice cake fuel in the warm, fuzzy glow that only Rapha pulls off. His parody, embedded after the break, was shot with SF Composite High School mountain bike team riders and is pure awesome.


Trailside Review – Bearded Brothers Raw, Natural Real Food Energy Bars

Bearded Brothers raw vegan real food nutritional energy bars review

While the brand name may not conjure up images of delicious food, Bearded Brothers’ raw, 100% natural and vegan friendly bars are, in fact, quite delicious.

They’re made from real, whole foods like dates, almonds and other nuts, dried peaches, coconut, cocoa, chia seeds, cinnamon and more, most being organic. The texture’s lightly moist, and satisfyingly hefty such that you need to give it a few noshes before swallowing, but not so thick or dry it needs immediate chasing with water. You can let the flavor linger a bit and enjoy.

Four flavors -Blueberry Vanilla, Ginger Peach, Maca Chocolate and Coconut Mango- are made in small batches in Austin, TX, using raw, vegan, 100% natural ingredients that are free of gluten and soy. Each 20z bar packs roughly 240 calories. Check below for ingredients lists and mini review…


Physiology and Nutrition: Why Not Gels, Part 2

biol-3-1-3It seems I hit a nerve with my last post on “Why No Gels”.  There is a nuance to be highlighted with regards to performance nutrition: the separation of fatigue due to a drop in blood volume and fatigue due to a lack of carbohydrate.  This Part 2 will focus on the basic physiology to give insight on Part 1 (as well as some solutions!)

Open any exercise physiology textbook and the first factor of fatigue is a drop in blood volume, with the second factor of fatigue decreased carbohydrate availability. Why? Simplistically, you can rectify low circulating carbohydrate pretty effectively by eating something and feeling the effects within minutes. A drop in blood volume is more complex, and it takes hours to rectify (as it involves the kidney regulatory hormones aldosterone and arginine vasopressin).

Blood volume is the red cells and plasma in circulation. When discussing exercise and fluid shifts, the term “plasma volume” is often used, as this refers to the watery component of blood. With the onset of exercise, there is a shift of blood flow to supply the working muscles and to the skin, to divert the increased heat produced (from muscular contraction). With the increased demand for blood to the muscles and skin, there is hypoperfusion of other organs, including hypoperfusion of the GI system.

As exercise continues and plasma volume is lost through sweating, breathing, and gastrointestinal water usage, available circulating blood diminishes (there is less overall water in the blood, thus it is “thicker”).  An endurance athlete will feel the drop in blood volume as “muscle fatigue”. As the viscosity of blood increases, the competition between the skin and muscles becomes fiercer; with the skin winning over muscle perfusion.  Heat is a large threat to the body, the actual window of survival core temperature perturbation is quite narrow: 37-39.5°C (98.6-103.1ºF – Athletes often push themselves to a core temperature of 40°C before true adverse effects of heat stress are seen.). As heat storage of the body increases and more blood is shunted to the skin, there is less blood for muscle metabolism- nature’s purpose: shut down the threat. By this, I mean, less blood for muscle metabolism means fewer contractions, thus less heat produced (the temperate of the muscle itself contributes to fatigue as well by denaturing the contractile proteins). This is muscle fatigue – a drop in power. In a traditional mentality, this is when an athlete will typically reach for a gel or other quick hit of carbohydrate, thinking they are low in carbohydrate; but it is water deficit of the blood that forces the fatigue.
