Selouyanov on Endurance (Pt. 2): More Russian Sports Science from Dr. Smet

Guest author “Dr. Smet” finishes his insider’s tour of the Russian sports science underlying Pavel Tsatsouline’s long-awaited endurance training manifesto, The Quick and the Dead. I follow Dr. Smet’s blog Girevoy Sport After 40 to read about top-dog Russian coaching and research from a medical scientist who also practices what he reports on.

Before we start I have to make a disclaimer of sorts. Soviet sport scientists then and Russian scientists now often have fragmented interest and education in the field. Throughout his lectures Selouyanov makes statements that are debatable, to say the least, even though he doesn’t seem to have experience in the subject. For example, his view is tht the only way to increase the strength of the glycolytic muscle fibers is to lift maximal weights to failure. Therefore, if some powerlifters don’t follow that rule and still get strong – that must be steroids, no other explanation is possible. I am not qualified to argue the subject and am only conveying Selouyanov’s work, so take it or leave it. 

So let’s get to the most relevant parts of Selouyanov’s teachings. 

Muscle fibers 
Muscle fibers are loosely divided into three types, depending on the activity of the enzymes, in poarticular ATP-ase. Oxydative muscle fibers (type I) have slow ATP-ase, their speed of contraction is slow and they are resistant to fatigue. Glycolytic muscle fibers (type II) have fast ATP-ase, contract quickly and can be either resistant to fatigue (Type IIA) or not (Type IIB). 
For the purpoose of training muscle fibers can be looked at in the following way:
Oxidative fibers – have mitochindrial mass that cannot be developed further. Each myofibril is surrounded by a layer of mitochondria. These fibers use fatty acids in the active state. 
Intermediate fibers – have lower number of mitochondria. As the result two processes occur during activity: aerobic glycolysis and anaerobic glycolysis. During activity lactate and hydrogen ions are accumulated, so these fibers develiop fatigue, but not as fast as purely glycolytic type. 
Glycolytic fibers – have no or little motochondria, so that anaerobic glycolysis predominates, with the resulting accumulation of hydrogen ions and lactate. 

Factors that determine endurance

According to Selouyanov the difference in endurance can be fully explained by several factors. 
1) First, the development of the oxidative muscle fibers. Among well trained endurance athletes oxydative muscle fibers comprise 90 – 100% of the total muscle mass, therefore they don’t produce lactic acid in excessive quantities that cause significant acidosis and the resulting decline oin performance. To the contrary, among untrained individuals 50% of muscle consists of intermediate muscle fibers which, during their progressive recruitment during exercise, accumulate lactate. 
2) The second reason for better endurance among trained individuals is that their aerobic system switches on earlier, mostly because they have more oxidative fibers, so that the initial production of lactate is lower. 
3) Trained individuals utilize lactate more efficiently. Mitochondria are capable of utilising piruvate, and in the oxidative fibers piruvate is produced from lactate. 
 Fourth reason for better endurance – increased volume of the circulating blood. This, in turn, results in the reduced concentration of produced lactate.
The role of the heart. 
Endurance training leads to the dilatation of cardiac ventricles. This, in turn, makes cardiovascular system more efficient, in the way that the same cardiac output – the amount of blood the heart is capable of pushing though per minute – is achieved by fewer contractions. Training of the heart is a separate topic and will not be discussed here. 

Three types of exercises
All types of exercises utilised for the training of grapplers can be divided into three types. 

Effective exercises. 

  • Dynamic, maximal anaerobic power, to failure – facilitate the development of myofibrills in glycolytic and intermediate muscle fibers
  • Stato-dynamic, of maximal anaerobic power (100%), to failure (pain) – develop myofibrills in the oxidative and intermediate muscle fibers
  • Dynamic and stato-dynamic, of maximal alactic power, done to less than ½ of the limit, performed the light local muscular fatigue, repeated after normalisation of acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers
  • Dynamic exercises of near maximal power (90%), done to less than ½ of the limit, performed till light local muscular fatigue, repeated after the elimination of acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers
  • Dynamic exercises of submaximal (60 – 80%) power, done to less than ½ of the limit, performed till light local muscular fatigue and repeated after the elimination of excessive acidosis – facilitate some increase of the myofibrills and mitochondria in the glycolytic and intermediate muscle fibers

Harmful exercises.

  • All exercises of near or sub-maximal anaerobic power, as well as those of maximal aerobic power performed to the limit and causing excessive acidosis (pH < 7.1, lactate > 15 nMoll/L).

All other types of exercises have little useful effect for the development of endurance among grapplers. 
According to Selouyanov there are two ways to increase endurance and strength in skeletal muscle: increase the number of myofibrills and increase the number of mitochondria. Both are achieved differently in glycolytic (and intermediate) and oxidative muscle fibers, therefore we are left with four training modalities. 
In order to increase myofibrillar mass four factors must be present. 

  • Reserve of amino acids in the muscle cell (provided by consuming protein)
  • Increased concentration of anabolic hormones as the result of mental strain
  • Increased concentration of free creatine in muscle fibers
  • Increased concentration of hydrogen ions

Increasing the number of myofibrills in the glycolytic muscle fibers.
I suspect this part will make quite a few of us cringe. However, the goal of this post is to convey Selouyanov’s opinion on optimal training, so bear with me here. [Editor’s note: In effect, Selouyanov is about to ignore a core doctrine of Pavel Tsatsouline’s, namely the taboo against training to failure.] Glycolytic muscle fibers are activated when maximal muscular effort is required and no earlier. Therefore (according to the good professor), the growth of glycolytic muscle fibers can be achieved only by utilising weights of of maximal or near maximal intensity. The following conditions have to be present:

  • Intensity of maximal or near maximal intensity – more than 70% of 1RM
  • Exercise is performed to failure, i.e. to full exhaustion of CPn and achievement of high concentration of free creatine
  • Number of repetitions – 8 – 12. Last couple of reps have to be forced (with the help of a partner)
  • Rest – 5 minutes. Should be active, aerobic activity at HR of 100 – 120/min, this helps to utilise lactic acid
  • Number of sets: 7 – 9 if the goal is growth, 1 – 4 for tonic effect
  • Number of training sessions per day – one or two, depending on the intensity and athlete’s condition
  • Number of sessions per week – synthesis of myofibrills takes about 7 days, this is how long the athlete should rest after a training session done to the limit.

Myofibrillar hyperplasia in the oxidative muscle fibers
The method for developing myofibrills in oxidative fibers is similar to that for glycolytic muscle cells. With the exception that exercises are performed without relaxation. In that case the capillaries in the muscle are compressed, limiting circulation and leading to the hypoxia of the muscle fibers and the accumulation of lactate and hydrogen ions. 
I suspect this works similar to the occlusion (Kaatsu) training that became somewhat popular in the recent years. Selouyanov believes that mostly slow/oxidative muscle fibers grow under these conditions – Smet. 
To get the idea of this method imagine a barbell squat. Except that it is performed in the way that doesn’t allow for the pause at the top, with incomplete range. This way the muscles are continuously contracted to one degree or another, and after 20 – 30 seconds you get the burn, which is the desired effect. 
The conditions for the efficiency of this method are as follows: 

  • Intensity – medium: 20 – 40% of 1RM
  • No relaxation pohase during exercise, the muscles are continupusly contracted
  • Tempo and duration – slect the weight so that the athlete can perform 25 repetitions in 30 seconds. Last few repetitions should cause significant pain.
  • Rest – 30 seconds (active)
  • This exercise is performed in series of 3 – 5 sets. 25 reps in 30 seconds equals one set.
  • Number of series in one session: 1 – 2 for the tonic effect, 3 and more for growth.
  • Number of sessions per week – exercise is repeated in 3 – 5 days.

There is no mention of rest between series. I suppose it is several minutes, until the muscles feel relatively fresh.
Selouyanov recommends doing exercises aimed at growing muscle fibers at the end of the training session and better in the evening. If other types of training is done after this the reduction of glycogen can negatively interfere with the protein synthesis and impair growth. 
Development of mitochondria in skeletal muscle
Formation of mitochondria is controlled according to the principle of the functional criteria. According to this criterion, mitochondria that cannot properly function are eliminated. 
One of the natural factors leading to the destructurisation of mitochondria is hypoxia (e.g. being at altitude) and accompanying anaerobic metabolism. Similar processes occur during anaerobic training. 
Several generalisations can be made in regards to mitochondria: 

  • Mitochondria are energy stations of the cell and supply ATP by aerobic metabolism
  • Mitochondrial synthesis exceeds the destruction during conditions of their intensive functioning (oxidative phosphorilation)
  • Mitochondria tend to appear in the areas of the cells where the delivery of ATP is required
  • Intensive destructurisation of mitochondria occurs when the cell is functioning at high intensity in the presence of anaerobic metabolism which leads to the excessive and prolonged accumulation of ydrogen ions in the cell

Based on the above it is possible to develop methods of aerobic development of the cell. Every skeletal cell contains three types of muscle fibers. 

  • Those that are activated regularly during every day activity (oxidative)
  • Those activated only during training requiring moderate muscular activity (intermediate fibers)
  • Those that are seldom activated – only during maximal or near maximal effort, such as jumps, sprints etc. (glycolytic fibers)

In well trained individuals oxidative muscle fibers are maximally adapted. In other words, the number of mitochiondria in these muscles cannot be developed any more. It has been demonstrated that aerobic training at the level below anaerobic threshold in well trained athletes has zero value. 

Therefore, in order to increase aerobic potential of the muscle fiber it is necessary to build structural basis – new myofibrills. New mitochondria will then develop around these myofibrills. There is a special methodology which has been tested: interval training using two exercises. For example, pushups and pullups from low bar (unloaded, so that the feet are resting on the ground). 

General principles of such training are as follows: 

  • Exercises are performed at low intensity, i.e. 10 – 20% 1RM
  • Exercise is performed at medium or fast tempo
  • Full ROM is utilised
  • Duration – until early signs of local muscular fatigue
  • The template – 5 – 8 repetition of one exercise is followed by 5 – 8 repetitions of another without rest – that is 1 set
  • No pauses between sets
  • Number of sets – 5 – 10 (determined by the degree of fatigue) – that’s 1 circle
  • Number of circles in a session – 1 – 5 (fatigue and is determined by the glycogen stores in muscle tissue)
  • Session done at maximal volume can be repeated after 2 – 3 days, after glycogen stores are restored

Gear Check

Final installment in my after-action report from the GORUCK D-Day Heavy Challenge.

The faithful, indomitable, light, nimble “Moose Head” rucksack. I love this thing. Made in the 1930s, it was intended by the Swedes as a cheap mass-production item for hurriedly equipping a big army that Germany would choose not to tangle with. Eighty years later, with just a little sewing, it’s my favorite pack.

What Worked Out Great

1. Webbing: I had about 6′ of webbing and it saved me twice. First we had to carry an insidiously-shaped rock a few miles uphill. I bound it up like a birthday gift and then some genius added D-rings and carabiners so that folks could hang it from their pack straps. The final effect was like a newborn boulder in a Babybjörn. It still sucked, but it substantially reduced the Suck Value. Second, I broke a pack strap at dawn, but it took all of 30 seconds to improvise a fix with the webbing. Without it, I would probably have washed out of the event over that petty equipment failure. So write this down, someone: webbing is the duct tape of rucking.

Weight: 40g. Not quitting the whole event over a busted pack strap or wasting everyone’s biceps cradling a f#&%ing rock: priceless.

2. Spare shoelace: Whipped this out to secure the flag to the pole better. Again, it nullified what could have been a huge pain in the butt for essentially zero added weight.

3. Rocky S2V boots: Thank you, Sgt. Šileika! The Rockies were champs. My search for the perfect all-round boot is over!

I’m blown away by the contrast to the Moab Ventilators that I wore last year. The point of the Ventilators is that, with their mesh sides, they let water and sweat flow out and let air rush in. It’s a great idea for running trails, but not for sloshing around in surf and sand because your shoes and socks fill with sediment. I got grit between my shoes and socks, between my socks and sock liners, and between the liners and my skin.

Perhaps not coincidentally, the other teammate who wore Rockies completed a “Heavy-Tough-Light” (i.e. he is a freak who did three events back-to-back over 48 hours, totaling well over 70 miles). And the teammate who wore Ventilators got a silver dollar-sized blood blister so heinous and unearthly that I expected an alien to spawn from his heel. (Amazingly, he just cheerfully popped it, dressed it, and walked on it for the next 12 hours without grimacing. People are freaks, and this guy must have the pain tolerance of a barn animal.)

4. Synthetic fabrics: Impressed by Lean Solid Girl’s successes, I left behind most of my old-school cotton, wool, and hair shirts and wore so much stretchy space-age fabric that I felt like Spider Man. And it worked great: I stayed warm, dry, windproof, and free of chafing.

It was only at midday that I wore a cotton shirt (one of the dozen awesome $4 Bundeswehr quarter-zips that I stash everywhere–#notaffiliatedIjustlovethem). But as soon as we got wet, I changed back to polypro gratefully.

5. Tights: Goofy yoga shorts are still great, but in water and wind, I was even happier with running tights. Even better, mine had built-in knee pads.

6. Categorized bags: Since my old-fashioned ruck only has one big compartment, I sorted gear into four marked bags: Food, Shirt, Jacket, and Head & Foot Stuff (hat, headlamp, sunglasses, socks, and foot care supplies). It worked great. Next time, I’ll color code the bags too.

7. More sock changes than a Madonna concert: I brought two extra pairs of socks and sock liners, and I rotated through all of them. Again, cheap insurance. I’ve had great success with the combination of Finnish M05 “liner socks” (which are socks unto themselves here in temperate climes) and FoxRiver liners, so I won’t mess with success.

8. Tailwind and GU: Here too, I owe Lean Solid Girl, who’s a past (and future?) runner, for initiating me into the secrets of distance athletes.

9. My hydration bladder: Our team had at least two burst hydration bladders, which did not enhance their owners’ lives. Usually I’m the first person to cheap out and get suckered by a false economy, but I’ve never encountered this problem even after hundreds of miles, so I’ll keep using Hommitt.

Dumb Ideas

1. Powerlifting knee sleeve: It’s stupid to change your game plan at the last minute, and that includes switching to gear you haven’t tested. I grabbed a squatting knee sleeve on the way out the door because I worried about padding my sore knee. It guarded my knee from abrasion, alright, but over 40 miles it knotted up some soft tissue behind my knee from the pressure.

2. Leaving my electrolytes to chance: I prepared for pushups poorly enough. I didn’t need cramped arms on top of that, but I chose to trust that I’d get all my electrolytes from the Tailwind. Dumb. Electrolytes are cheap insurance, just like webbing or an extra shoelace. Without Mike the Forester’s generosity, I’d have been in trouble. Next time I’m bringing extra electrolytes.

3. Poorly secured pill bottle: To help with pain, I cleverly brought some CBD, ibuprofen, and caffeine pills, but I foolishly hung the bottle from a carabiner with my gloves, and within an hour it was lost.


Today’s the day, friends. 24 hours, 40+ miles, with logs, sandbags, PT beatdowns, and surf torture along the way.

Wherever you are today, get after it! Hammer along with me and (I’m completely serious about this), please remember my team and me in your thoughts and prayers. I may be Buddhist, but I’m not choosy about where I get my numinous intercession.

Everyone Should Do LSD

Part 4 of our series “The Tao of the Lazy Badass”

Long, Slow Distance

I hate to say this, but your single biggest priority is to create some modest aerobic base. If you were cursed by an evil genie to be allowed only one kind of exercise, it would need to be something aerobic.

Come on, Eighties, you’re better than this.

Why do I hate saying that? Because it sounds so 1980s, when America fetishized cardio to the neglect of all else and said we should avoid dietary fat and live on bagels and pasta. 

But you get the most happiness, health, leanness, and energy from a modest dose of easy aerobic exercise.

And I really do mean easy. I’m talking a maximum heart rate of 180 minus your age. That’s nothing. Unless you have a good aerobic base already, that’s probably just a fast walk while swinging your arms. 

And the great part is, you benefit MUCH more from that easy pace than by pushing yourself. If you care about why, read the writings of endurance super-coach Phil Maffetone. Maffetone trains elite athletes mostly or entirely in that 180 Minus Age zone, which is also where the endorphins and the bliss are. But whether or not you concern yourself with the “why?” the important point is this: by keeping your heart rate low, you IMPROVE the training effect. You are not compromising your training by going easy. You will outperform the people who train at too high a heart rate (which is almost everyone).

How do I figure out my heart rate?

The Polar FT1. It’s old, basic, debugged, and the least expensive of the reliable, useful ones. If Stalin had a heart rate monitor, it would be this one.

Buy a heart rate monitor. You’ll need to spend about $60 for an adequate, reliable basic model. Frugal to a fault, I seldom recommend throwing away money on wiz-bang fitness devices. But a heart rate monitor is one of the few exceptions. It really does help SO much that it’s a must-buy even for a tight-fisted Buddhist stoic who thinks that if the Red Army considered something an unnecessary frippery, you can too.

No, you don’t need to start running

Leonard’s Schwartz’s forgotten classic, Heavy Hands. Run, do not walk, to this book. Or at least power walk there.

So do I mean that you should start walking or running? Nope. Do anything that elevates your heart rate to that magic number and holds it there steadily. You can ride a bike, roller blade, paddle or row, ski or snowshoe, and you might also really like another obscure activity from the 80s called HeavyHands. Trust me on this one: HeavyHands is awesome and makes you feel incredible. 

The Tao of the Lazy Badass

“Like water, volume is soft and yielding. But volume will wear away rock, and it beats the crap out of excess fatigue. As a rule, volume wins over fatigue. This is another paradox: what is soft and voluminous is strong.”

from the lost training manual of Laozi (Lao-Tzu)
A difficult book, but the most important one I know.

In the most original book on training in decades, Pavel Tsatsouline describes a certifiable badass, a special operations ninja-type whom he pseudonymously calls “Victor.” Victor combines a pair of already-extraordinary feats into an extra-extraordinary combination: he runs ultra-marathons of up to 100 miles AND he does pullups with an extra 160# hanging from his waist. That’s a freakish level of endurance and world-class strength, a combination so rare as to seem impossible. (As we have said before, strength and endurance are rivals.) That is what makes Victor an elite among the elite, a certifiable badass.

To reach those heights, Victor trains in a very special way: lazily. Or to be more precise, with low fatigue. From his amazing accomplishments, you might suppose that he spends all day exercising and puking his guts out. Nope. Most days he works out for all of 30 minutes, much of it with a 24kg kettlebell, which is strictly a “Joe Average” weight, and some pushups and pull-ups and yoga. He left behind even low-key barbell training long ago, explaining that when he deadlifted, “I felt my ego pushing me harder and faster than my body wanted to go. So I decided to limit myself to one kettlebell and two [steel exercise] clubs …”

As the core of his lethargic-looking super-routine, Victor runs … sloooooowly. Slowly enough to breath only through his nose, with rhythm and relaxation. He writes:

“The key is … the LOW INTENSITY. I use a heart rate monitor, and I stay at 60% to 65% of my [max heart rate]. This means that I am often walking on the hills. If I ran [faster], my recovery time would be much longer.”

Allyson Felix knows the Tao of the lazy badass. Her coach, Barry Ross, keeps his athletes fresh and unfatigued in training. See Easy Strength.

Pavel and Victor are insistent: Victor is not succeeding in spite of his low-key training but precisely because he throttles back. Victor has perfected one way of applying the near-magical formula for productive and happy training: do as much work as possible while staying as fresh as possible.

Are those twelve words too much to remember? Then stencil this on your kettlebells, barbells, and running shoes: Volume Without Fatigue. That is the red thread that runs through many of the successful training philosophies out there, connecting disparate-looking approaches whose only apparent link is that they work well, and it is the subject of our next series, “Farewell to Fatigue: The Way of the Lazy Badass.”

Your author. Not a badass, but I make up for it in laziness.
