About The Natural Running Center

In the beginning there was darkness, and runners seemed lost, confused, chronically injured, always experimenting with “bigger is better” footwear as a potential remedy. Then a new “less is more” approach emerged, a radical way of thinking led by a handful of scientists, athletes, coaches, and charismatic best-selling author. They looked backward to the past for inspiration. Soon, a healer and educator came forth. Collectively, they would become the shepherds to a flock of broken-down, often-sidelined runners accustomed to wearing conventional running shoes.

As it were, this health-conscious individual lived in Shepherdstown, West Virginia, the oldest town in the state and just up the road (and river) from Harpers Ferry. His name is Dr. Mark Cucuzzella, a family physician and an elite runner, who, in his early 40s, can still reel off sub 2:40s at the Boston Marathon. Mark had a singular vision regarding the need to spread the gospel of natural and minimalist running to the masses. In early summer 2010, he opened the first minimalist running store in the nation. He called it Two Rivers Treads because culturally and historically vibrant Shepherdstown is located near the confluence of the Potomac and Shenandoah rivers.

Mark and his tiny store became a fixture in the natural running community, Coaches, athletes, trainers, physical therapists, bloggers, and runners from near and far became connected to one another through Two Rivers Treads.

Then along came Bill Katovsky, a two-time Hawaii Ironman finisher, founder of Tri-Athlete magazine, and author and editor of several health and fitness books. He lived in the San Francisco Bay Area, but heard of Mark when he started his own blog Zero Drop in late fall 2010. He had just come out with his latest book, “Return to Fitness: Getting Back in Shape after Injury, Illness, or Prolonged Inactivity.” Though Katovsky has once been a multisport jock, he barely broke a sweat in his 40s. Nor did he run during that Lost Decade. So when he returned to fitness and running, he threw out his old running shoes with their big heels and cushiony treads, and after hours of frustrating and bewildering research on the Internet, finally bought a pair of minimalist running shoes that a trail-running acquaintance recommended, removed their insoles, and began his own journey that eventually took him to Mark’s doorstep.

Together, they decided to launch the Natural Running Center (NRC) to serve as a comprehensive web resource of information and education for all runners. They sensed new, seismic changes affecting the running world, changes that would only broaden and solidify, and they wanted to help shape this early-adopter’s movement via learning and sharing of helpful resources. In late winter 2011, they began mapping out the mission of the Natural Running Center and how best to objectively disseminate information, bring other like-minded individuals into the NRC fold, and yet avoid the distraction of mind-draining dogma and reckless bias.

To help them reach these goals, they reached out to Nick Pang, also a West Coaster, who was a self-described web technologist living with his family just north of Silicon Valley. For twenty-five years, Nick was a serious runner before he got injured in traditional running shoes. He then saw the light two years ago in minimal shoes. He gradually retooled his gait and form, and began to run injury-free. Based on his own experiences, in the summer of 2010, he created the Minimalist Running Shoes website that quickly became an important destination for anyone looking for shoe reviews in this rapidly expanding sector of the footwear market.

The three minimalist amigos approached Damien Tougas, a web programmer living in Maine, who recognized that runners, walkers, and hikers need to be at the forefront of this grassroots revolution. In January 2011, he launched Toe Salad, a forum by the people and for the people who were interested in learning from the folks actually experimenting in this new barefoot lifestyle. Toe Salad would also have a highly visible presence and affiliation with the Natural Running Center.

An advisory board of health, science, medical, and coaching experts was next created for the Natural Running Center. Its purpose was twofold:  to exchange knowledge and ideas with one another; and to easily communicate their findings and writings with all runners.
And thus the Natural Running Center was born– a virtual home for this new “re-evolution” in running.  Like our tagline says– “Learn, Evolve. Run!”

Review of the VivoBarefoot Neo (versus Vibram) « ZERO DROP

Posted on 21:38 by Unknown
Review of the VivoBarefoot Neo « ZERO DROP

"....Nick Pang, who is the creative force behind the  popular blog, Minimalist Running Shoes, wrote that “going from the Vibram FiveFingers KSO to the Evo II is like upgrading from coach to first.”

The low-slung, uniquely designed Neo is a minimalist running shoe that doesn't look like a running shoe.

A “barefoot running” shoe is a curious concept, or what is often called an oxymoron such as “doing nothing,” “friendly fire,” “dry martini,” or “deafening silence.” You either run barefoot or you run in shoes. You can’t do both at the same time, unless you’re one of those quantum-theorizing physicists, who always name your cat Schrodeinger and like hanging out at the neighborhood multiverse Starbucks simultaneously drinking a caffe latte and caffe mocha. A barefoot running shoe, however, has developed into a valuable marketing concept ever since it commercially rode bareback into stores on the natural running and minimalist movement. Here’s a shoe that can simulate going unshod (in an approximate sense), but your soles won’t turn jet black from street crud (like Homer Simpson’s once did when he decided to become a sixties’ poncho-wearing flower child for one episode).

Vibram’s FiveFingers was the first to get a significant toehold in the barefoot running shoe market, and sales continue to soar upward each year. But for all its popularity, VFFs don’t seem to make the BFF list with many traditional runners who love hurling all sorts of derogatory epithets at the simian-looking sneaker. “Monkey feet” is a favorite anti-VFF expression. So when other companies like Merrell and Terra Plana came out with a more conventional-looking barefoot running shoe, it was easy to imagine what happened next: it generated many new converts to barefoot-running shoes.

For the past several weeks, I have been running in Terra Plana’s barefoot running shoe that is called the VivoBarefoot Neo; it’s a less expensive version (by forty bucks) of the first-generation Evo. A name like Neo can become  a tricky issue if you are a fan of the “Matrix” trilogy, and don’t like being used as a tool by secret, sinister forces. But I never saw any of the films. I had the urge to try out the Neos because I wanted to experience more of a barefoot-running, zero-drop sensation than I get with my Nike Frees. There was no Morpheus urging me to morph to more minimalism. No red pill. No blue pill. In other words, I was literally exercising my own free will.

Because I have wide Fred Flintstone feet, many minimalist shoe brands are inhospitable to my dogs. Going through life as an EEEEE ain’t easy. (Prom night was especially painful--narrow rented shoes, ridiculously looking tux, and reluctant date in that quick order.) So you learn to read online running shoe reviews with a healthy skepticism and an abiding hope that maybe, just maybe, the shoe being described by a blogger is the long-awaited one for your tugboat-size feet.

Mark Cucuzzella, M.D, elite runner, and owner of Two River Treads, first told me about the Evos. He’s a huge fan of them. Here’s how they are described on his store site: “The 4mm outer sole provides excellent ground feel and response time and is very durable and puncture resistant.....the same material as lightweight bullet-proof vests. The fit of the Evo is unique compared to other minimalist running shoes. The shoe hugs the area around the upper heel. The entire midfoot and forefoot area have ample room to move within the shoe. This creates the unique experience. Unlike other minimalist shoes that attempt to mold to your foot, the Evos allow your foot to move within the shoe without producing friction. I love this shoe for all activity from running, to golf, to walking around town, and occasionally sneaking into work on casual day.”

Another minimalist running pal, Nick Pang, who is the creative force behind the  popular blog, Minimalist Running Shoes, wrote that “going from the Vibram FiveFingers KSO to the Evo II is like upgrading from coach to first.”  Nick especially liked the shoe’s intimate rapport with Mother Earth. “The ground feel and my running form is unaltered in the Neo just like the Evo II. If this is your first pair of VivoBarefoot minimal shoes, you will feel the ground immediately with your first foot strike and you may have to adjust your running form (unless you came from barefoot running) – run lightly. If not, you will hear your shoes striking the ground in a loud and noticeable noise. Listen to your foot strike and tread lightly.”

On my first run in the Neos, I went five miles-- a distance far too much for a zero-drop newbie, but more on that later. I was amazed at how comfortable my feet felt in them-- I had removed the inner soles and I wore normal socks.  I could have a sublet the extra space in my shoes to a family of gypsies and still have plenty of room for my toes.  They are especially light. I also immediately noticed several other things. I was running too loudly, the soles slapping the road like a pissed-off beaver with its tail. With the Nike Frees, in contrast, I loped quietly. The excessive decibels came from an altered foot strike-- more up front near the ball than I was accustomed to. My soles also felt the pavement. It was definitely not a smooth ride during that initial run.

Hoping for a bit more cushion, I re-inserted the inner soles for subsequent runs in the Neos. Moreover, I decided to only run two or three miles each time in them, because I felt something odd or twingeing going on in the plantar area in the right foot. Because my feet were landing differently, new muscles, tendons, and ligaments were being put to the test. And since I was well aware of the high frequency of foot injuries to those who don’t take sufficient time to ease into a barefoot running shoe regimen, I saved my longer runs for the Frees. Shoe rotation is a good thing; it doesn’t mean you are backsliding.

On the aesthetic side of the ledger, the Neo’s canvas-like uppers and colors are rather ho-hum, whereas the honeycomb tread pattern of the soles are killer to look at. I was sent a black pair by the company to review.  I had never run in black sneakers before, so that took some time getting used to.

I will continue to run in the Neos because they will help strengthen my feet and make me more aware of an optimal "loading rate," which is the foot's relationship to the body's center of gravity during each stride. With that said, running on the rocky trails in Neos has not been a picnic. I was required to pay extra close attention to where each foot landed, and I definitely felt the small rocks underfoot. But running on asphalt is a different story. On this more even surface, my proprioception was able to switch to cruise control. I still need to learn to run more quietly. Come this fall, there will be a trail version of the Neos. By then, I hope to be running as noiselessly as Natty Bumppo in “The Leatherstocking Tales.”

Why VIVOBAREFOOT

VivoBarefoot

In 2004, Terra Plana became the pioneers of the barefoot-shoe movement by launching VIVOBAREFOOT, the first minimalist shoe with a patented, ultra thin puncture resistant sole that offers maximum sensory feedback and maximum protection.
In 2010, the American Academy of Physical Medicine and Rehabilitation and Harvard University, both released studies to support that barefoot reduces injuries, reserves energy, and improves technique.

As scientific support for barefoot health grows, so does demand for VIVOBAREFOOT and the collection features the most comprehensive line of minimalist shoes on the market. The VIVOBAREFOOT difference is in the sole. We make a series of constructions specifically designed for varying elements, terrains, and activities. From high performance off-road and trail running shoes, to work and kids shoes, VIVOBAREFOOT offers a total lifestyle solution for the whole family and options for transitioning from walking to sports.

As with all Terra Plana products, VIVOBAREFOOT footwear is produced sustainably using recycled, locally sourced materials, with efficient and eco-friendly production techniques, in independently monitored ethical factories. Sustainable, it must also be comfortable and durable in quality and style.


Disclaimer: At the time of print our shoe box leaflets had an inaccuracy in the text. Above is the correct description of good barefoot running posture. Please refer to our instructional videos on successful transition to barefoot running, for further guidance.

Pint-sized former Mr Universe turns 100 in India


In this Friday, Mar 16, 2012 photo, Indian body builder Manohar Aich flexes his muscles as he poses for a photograph in a gymnasium in Kolkata, India. -- PHOTO: AP
KOLKATA, India (AP) - A former Mr Universe who is one of the shortest winners of the body building contest has turned 100, saying on Sunday that happiness and a life without tensions are the key to his longevity.

Mr Manohar Aich, who is 150cm tall, overcame many hurdles, including grinding poverty and a stint in prison, to achieve body building glory.

His children, grandchildren and great-grandchildren gathered Sunday in the eastern city of Kolkata to celebrate his birthday the day before. Hindu priests chanted prayers while a feast was laid out to honour Mr Aich, winner of the 1952 Mr Universe title.

Rippling his muscles and flashing a toothless grin, Mr Aich says his ability to take his troubles lightly and remain happy during difficult times are the secrets to his long life. That, and a simple diet of milk, fruits and vegetables along with rice, lentils and fish have kept him healthy.

Gaining muscle and losing fat at the same time: A more customized approach based on strength training and calorie intake variation

Posted on 10:02 by Unknown
Health Correlator: Gaining muscle and losing fat at the same time: A more customized approach based on strength training and calorie intake variation


Monday, March 12, 2012

Listen to this article. Powered by Odiogo.com

In the two last posts I discussed the idea of gaining muscle and losing fat at the same time (1) (2). This post outlines one approach to make that happen, based on my own experience and that of several HCE (3) users. This approach may well be the most natural from an evolutionary perspective.

But first let us address one important question: Why would anyone want to reach a certain body weight and keep it constant, resorting to the more difficult and slow strategy of “turning fat into muscle”, so to speak? One could simply keep on losing fat, without losing or gaining muscle, until he or she reaches a very low body fat percentage (e.g., a single-digit body fat percentage, for men). Then he or she could go up from there, slowly putting on muscle.

The reason why it is advisable to reach a certain body weight and keep it constant is that, below a certain weight, one is likely to run into nutrient deficiencies. Non-exercise energy expenditure is proportional to body weight. As you keep on losing body weight, calorie intake may become too low to allow you to have a nutrient intake that is the minimum for your body structure.

Unfortunately eating highly nutritious vegetables or consuming copious amounts of vitamin and mineral supplements will not work very well, because the nutritional needs of your body include both micro- and macro-nutrients that need co-factors to be properly absorbed and/or metabolized. One example is dietary fat, which is necessary for the absorption of fat-soluble vitamins.

If you place yourself into a state of nutrient deficiency, your body will compensate by mounting a multipronged defense, resorting to psychological and physiological mechanisms. Your body will do that because it is hardwired for self-preservation; as noted below, being in a state of nutrient deficiency for too long is very dangerous for one's health. Most people cannot oppose this body reaction by willpower alone. That is where binge-eating often starts. This is one of the key reasons why looking for a common denominator of most diets leads to the conclusion that all succeed at first, and eventually fail (4).

If you are one of the few who can oppose the body’s reaction, and maintain a very low calorie intake even in the face of nutrient deficiencies, chances are you will become much more vulnerable to diseases caused by pathogens. Individually you will be placing yourself in a state that is similar to that of populations that have faced famine in the past. Historically speaking, famines are associated with decreases in degenerative diseases, and increases in diseases caused by pathogens. Pandemics, like the Black Death (5), have historically been preceded by periods of food scarcity.

The approach to gaining muscle and losing fat at the same time, outlined here, relies mainly on the following elements: (a) regularly conducting strength training; (b) varying calorie intake based on exercise; and (c) eating protein regularly. To that, I would add becoming more active, which does not necessarily mean exercising but does mean doing things that involve physical motion of some kind (e.g., walking, climbing stairs, moving things around), to the tune of 1 hour or more every day. These increase calorie expenditure, enabling a slightly higher calorie intake while maintaining the same weight, and thus more nutrients on a diet of unprocessed foods. In fact, even things like fidgeting count (6). These activities should not cause muscle damage to the point of preventing recovery from strength training.

As far as strength training goes, the main idea, as discussed in the previous post, is to regularly hit the supercompensation window, with progressive overload, and maintain your current body weight. In fact, over time, as muscle gain progresses, you will probably want to increase your calorie intake to increase your body weight, but very slowly to keep any fat gain from happening. This way your body fat percentage will go down, even as your weight goes up slowly. The first element, regularly hitting the supercompensation window, was discussed in a previous post (7).

Varying calorie intake based on exercise. Here one approach that seems to work well is to eat more in the hours after a strength training session, and less in the hours preceding the next strength training session, keeping the calorie intake at maintenance over a week. Individual customization here is very important. Many people will respond quite well to a calorie surplus window of 8 – 24 h after exercise, and a calorie deficit in the following 40 – 24 h. This assumes that strength training sessions take place every other day. The weekend break in routine is a good one, as well as other random variations (e.g., random fasts), as the body tends to adapt to anything over time (8).

One example would be someone following a two-day cycle where on the first day he or she would do strength training, and eat the following to satisfaction: muscle meats, fatty seafood (e.g., salmon), cheese, eggs, fruits, and starchy tubers (e.g., sweet potato). On the second day, a rest day, the person would eat the following, to near satisfaction, limiting portions a bit to offset the calorie surplus of the previous day: organ meats (e.g., heart and liver), lean seafood (e.g., shrimp and mussels), and non-starchy nutritious vegetables (e.g., spinach and cabbage). This would lead to periodic glycogen depletion, and also to unsettling water-weight variations; these can softened a bit, if they are bothering, by adding a small amount of fruit and/or starchy foods on rest days.

Organ meats, lean seafood, and non-starchy nutritious vegetables are all low-calorie foods. So restricting calories with them is relatively easy, without the need to reduce the volume of food eaten that much. If maintenance is achieved at around 2,000 calories per day, a possible calorie intake pattern would be 3,000 calories on one day, mostly after strength training, and 1,000 calories the next. This of course would depend on a number of factors including body size and nonexercise thermogenesis. A few calories could be added or removed here and there to make up for a different calorie intake during the weekend.

Some people believe that, if you vary your calorie intake in this way, the calorie deficit period will lead to muscle loss. This is the rationale behind the multiple balanced meals a day approach; which also works, and is successfully used by many bodybuilders, such as Doug Miller (9) and Scooby (10). However, it seems that the positive nitrogen balance stimulus caused by strength training leads to a variation in nitrogen balance that is nonlinear and also different from the stimulus to muscle gain. Being in positive or neutral nitrogen balance is not the same as gaining muscle mass, although the two should be very highly correlated. While the muscle gain window may close relatively quickly after the strength training session, the window in which nitrogen balance is positive or neutral may remain open for much longer, even in the face of a calorie deficit during part of it. This difference in nonlinear response is illustrated through the schematic graph below.


Eating protein regularly. Here what seems to be the most advisable approach is to eat protein throughout, in amounts that make you feel good. (Yes, you should rely on sense of well being as a measure as well.) There is no need for overconsumption of protein, as one does not need much to be in nitrogen balance when doing strength training. For someone weighing 200 lbs (91 kg) about 109 g/d of high-quality protein would be an overestimation (11) because strength training itself pushes one’s nitrogen balance into positive territory (12). The amount of carbohydrate needed depends on the amount of glycogen depleted through exercise and the amount of protein consumed. The two chief sources for glycogen replenishment, in muscle and liver, are protein and carbohydrate – with the latter being much more efficient if you are not insulin resistant.

How much dietary protein can you store in muscle? About 15 g/d if you are a gifted bodybuilder (13). Still, consumption of protein stimulates muscle growth through complex processes. And protein does not usually become fat if one is in calorie deficit, particularly if consumption of carbohydrates is limited (14).

The above is probably much easier to understand than to implement in practice, because it requires a lot of customization. It seems natural because our Paleolithic ancestors probably consumed more calories after hunting-gathering activities (i.e., exercise), and fewer calories before those activities. Our body seems to respond quite well to alternate day calorie restriction (15). Moreover, the break in routine every other day, and the delayed but certain satisfaction provided by the higher calorie intake on exercise days, can serve as powerful motivators.

The temptation to set rigid rules, or a generic formula, always exists. But each person is unique (16). For some people, adopting various windows of fasting (usually in the 8 – 24 h range) seems to be a very good strategy to achieve calorie deficits while maintaining a positive or neutral nitrogen balance.

For others, fasting has the opposite effect, perhaps due to an abnormal increase in cortisol levels. This is particularly true for fasting windows of 12 – 24 h or more. If regularly fasting within this range stresses you out, as opposed to “liberating” you (17), you may be in the category that does better with more frequently meals.

Hi Ned, Depending on the starting point, I would guess it's of similar difficulty to build muscle without gaining fat than it is to build muscle and lose fat at the same time. That is, the plan to cut fat, then build muscle, is flawed because of old bodybuilding myths. One can make it sound good in theory, but to someone informed, it is obviously false. I never understood the purpose of "calorie cycling." Changing hormonal balance will predispose someone to partition calories in a desirable way [to muscle, away from fat]. Micro-managing calorie intake between training and non-training days is probably only necessary for someone looking to achieve extremely low levels of bodyfat, like bodybuilder levels. Protein level is often a hotly debated topic. I think beginners can get away with less, but for people near elite status, you need more--maybe like 1g/lb. There's a big difference in body stress between my squat (2.5x bw) and my sister's, so I could only imagine people with 4x bw or so. My strength levels decrease if I don't consciously eat protein above appetite (I don't use protein powder--sometimes gelatin).

Hello Ned, Great post. I know this one was all about the food, but I hope you don't mind me asking two exercise questions. One, is there any way HIIT can fit into this? Before reading about the theory of supercompensation, I thought that brief, but intense, "aerobic" exercise (to the point of becoming anaerobic) was the one exercise proven to reduce fat, while also proving just as successful with strength gains (in less time = efficiency). So this would seem to achieve both "weight loss" and "muscle gain". Two, on a related note, say one were to include running sprints on top of the strength training you mention. Would there be two different supercomposition windows, one for sprints and one for weights? Or would these exercises need to be alternated? Thanks! And sorry if you answered these in the past. I've only recently discovered this excellent blog, and I'm making my way through the archives! Angela

Hi John. Definitely the perception among elite BBs is that a lot of protein must be eaten. The odd thing about this is that even an elite BB will not store more than 15 g/d of protein in muscle: http://bit.ly/esosFA

Hi Angela. Sprints tend to lead to some muscle gain, but not as much as weight training. The reason may be that it is difficult to achieve progressive overload beyond a certain point. Once you can do a 100 m sprint at a certain speed, it is difficult to keep on decreasing the speed. And if you keep on increasing the distance, you’ll soon be leaving the anabolic range. This a general problem that applies to many bodyweight exercises as well. You can make them more difficult, but only up to a point. Many people achieve a level of muscularity with sprint-like exercises that they are happy with, and then focus only on keeping it that way.

Very similar to "Lyle McDonald - The Ketogenic Diet". Maybe interesting to you, as he goes quite into detail about this.

Hi Anon. I am not sure the approach described in this post would be really ketogenic. See below: http://bit.ly/hqOTCY

You make the case one can store about 15g/day... ...What about daily potential protein loss/turnover? I would imagine it would be higher with higher muscle mass? I have been fortunate to train with two powerlifting world record holders [Joe McAuliffe, Tony Conyers] and both have told me about failures on a higher carb, low protein diet; I have read the same from others--Dan John, Mark Felix, Kai Greene--online. Of course things can be a little distorted when we're talking about someone like Kai Greene, being at the extreme in terms of muscle mass and anabolic drug use [probably--heh].

Hi John. Not stuffing oneself with protein is not the same as going on a low protein diet. Now, I’d be interested to know about details. It’d be great if I could get my hands on actual numbers of calories, macros, micros, exercise etc. employed. I hear all sorts of things from people. Once the numbers are entered into HCE, and a careful correlation/graph analysis is done, as in the post below, the picture is a lot different: http://bit.ly/vReN6y
