After experimenting a lot, I have arrived at some hard-won conclusions about boots for rucking.
As reported earlier, I rejected GORUCK’s own house brand of boots, the MACV-1. Though attractive and wonderfully light, they have so little tread that I kept slipping and falling on down slopes. Unacceptable. They also lack a “shank,” a stiffener in the sole that helps you toe off the ground when your arches are tired.
I also gave an audition to Rocky’s inexpensive RLW or “Rocky light weight” boots, which look like the big brothers of the MACV-1. They are reasonably light, deeply treaded, and tall enough that I can “double lace” them, i.e. lace the instep separately from the ankle. However, being an economy model, they have a seam in the heel that many purchasers complain give them blisters (I did have a bit of that too, but you can counter that with an Engo pad) and their tongues are constructed in a strange way that required a long break-in before they stopped rubbing my instep raw. I could have gotten past both these bugs, but crucially, these boots lack a shank. I wore them for a 42-mile training ruck, and after twenty miles I longed for that stiffened sole. By that point I had used up my foot muscles for the day and, lacking a stiff boot sole, I could not toe off the ground anymore and instead was reduced to short, choppy steps. Never again. Not for a long distances.
And of course I have plenty of heavy boots that could probably kick through concrete, like my plug-ugly surplus combat boots issued by Germany’s Bundeswehr. If a crocodile masticated and swallowed them, the German giants would just emerge from the other side perfectly serviceable. These are just the thing for search-and-rescue bushwhacking. And shanks, oh, the shanks! You could probably drive a nail with them. But at over a kilo each—only Iron Man has heavier boots—these are not boots you can wear for 50 miles.
No, the “Goldilocks” boot is Rocky’s S2V Predator, which is a medium weight (about 800g each) and has the all-important shank. They also scarcely need breaking in. I double lace them, use “ladder lacing” on my left instep (which apparently is bigger than my right), and it’s quick and easy for me to adjust the fit to my level of foot swelling and the terrain.
These work great with my preferred sock set-up, a FoxRiver liner sock inside a Finnish M05 liner sock. Together with my new, larger and wider boot size, these kept my toes happy, uncrowded, and essentially unblistered for the whole fifty miles of the Star Course. No burgerfeet!
Note that I still love jackboots! I still think of them as my best all-round boots, the ones I’d grab if you said, “Get your boots on, we’re going on a mystery adventure! I won’t tell you any details at all: beaches or woods or mountains or city, wet or dry, rain or snow or sun—it’s all a surprise! Maybe we’ll be gone for a day, maybe for a month.” That would be easy: I would wear my $20 rubberized East German jackboots and bring one extra pair of sliced up bed sheets footwraps.
But jackboots make sense as my ideal general-purpose boot, whereas here we’re talking specifically about walking 50 miles through a city at top speed, which is very specialized indeed.
Real distance athletes don’t precede a race with dry-heaving and M&Ms. But I am not a real distance athlete. I am a special snowflake.

I flew to Seattle a day early and retired to bed after a dinner of kaplau gai kai dao. That was a fateful choice, because I spent most of the night awake and hurling. Frantic to rehydrate and keep some food down, I bought a bizarre assortment of groceries which, alone among Safeway’s inventory, I could look at without puking. I fed well enough on chocolate milk, coconut water, kombucha, yogurt, and peanut butter M&Ms that, by game time, I no longer looked embalmed.
With hit list in hand, we adopted a “town and country” strategy, hitting the downtown waypoints first and saving outlying parks for the daytime. That way, we had access to all-night stores while our crew was sleeping. When they started supplying us after dawn, we’d be in residential neighborhoods with no traffic or parking troubles, and we would have ample daylight by which to navigate park trails. And psychologically, it was a bonus not to stare at the ugly industrial blight around Boeing Field in bright sun, and not to be caught downtown without a bathroom in broad daylight.
As we marched through Georgetown, Lean Solid Girl discovered something critical. Prior to the event, I had noticed that Google Maps can flatten your route appreciably if you use Cycling mode instead of Walking mode. With no one supervising me, I would have done that. But I hadn’t reckoned all the shortcuts—pedestrian staircases and stepped foot trails through ravines separating neighborhoods—that were impassable to bikes but usually made for pretty humane climbing, often with handrails to help you “row” your way up.
Luckily, back at the hotel, Lean Solid Girl couldn’t quite get herself to sleep. She was on her laptop crunching different options and called in the results: we would indeed save ourselves a couple of unnecessary climbs on Cycling mode, but it would cost us seven extra miles of walking. The Jolly Irishman and I gave our reply in unison: “No f—ing way.”
The reality of our partnership was that Irish was leading, running both nav and Instagram almost by himself, and I was just following. I hadn’t wanted to burden him with both jobs, but we both knew that he was the stronger teammate that night. I remained somewhat pukey and wobbly until 4am, and I suffered a second weakness I’d never experienced before at a GORUCK event: gnawing hunger. For the first time I was nowhere even close to ketosis and felt hollowed. So while Irish drove the bus, I concentrated on keeping up and not being That Guy, and I couldn’t contribute much more to the team effort than lusty singing in Russian and obscene but admiring remarks about our rival teams.
Two of these teams distinguished themselves above our other (playfully) hated adversaries and won my admiration. First were the pair we called simply “The French Guys,” and they were the shadows we couldn’t lose. Twice I thought we passed them for good, only to see them pop out a few miles later in front of us. We seemed to be following the same overall game plan, “town and country,” but walking slightly different roads. Just as we left our foot care stop at the University of Washington, they caught up to us again, but this time without their same calm élan. “Something’s wrong,” said Irish. “The tall one is in trouble.” I glanced over and saw both of The French Guys beholding the one fellow’s unshod foot with the look of an ambulance crew standing around regarding someone they’ve arrived to find irretrievably dead. We called over, asking how they were, and the taller man replied only, “It’s pretty bad,” but with tight lips and a tiny shake of the head that said “C’est fini.” Irish went over with tape and supplies and came back reporting foot trauma of biblical proportions, a blister running nearly the length of the foot. This was almost too much for me to bear. They’d already trooped 30+ miles, and I knew from bitter experience how wretched it felt to endure all that and still fail.
And I’d also been through the lonely trek awaiting his surviving companion, a dark-haired dude whom I imagined hailing from some seaside Mediterranean town. He might have tagged along with us, but he stuck by his friend while they sorted out a ride for him. We saw him once more at Magnusson Park, tailing us by half a mile, but then lost him completely. Later, at the finish line, we found no one with any news of him, but as we finally put down our pizza and beer and began packing up our car, we encountered him trudging up the home stretch, beaten down by his solo trip but well within the time limit.
The other team I held in awe were the ones Irish and I called simply “The Runners.” We saw them only once, at 3am on the 2-mile pedestrian causeway to Mercer Island. They had already hit the waypoint and were returning to the mainland when they passed us. At first they were visible to us only as a trio of headlamps, then as six legs half-illuminated by the causeway’s murky, otherworldly light. “Da f***?” I exclaimed to Irish. “Are they running?” They certainly were. When they passed us, we got only a fleeting glimpse but a memorable one: three men thundered past, pounding the cement hard with music playing, big guys by endurance sport standards. I winced to imagine what was happening inside their poor knees—running with weight is very hard on joints and not recommended except in emergencies—but be that as it may, these guys were awesome to behold.
As it happened, we would be on their tails for the rest of the night. At each waypoint our crew would mention three guys right ahead of us, but Irish and I saw no one. Apparently we were gaining on them, closing the gap from 30 minutes to ten, but never spotted them. It was only at the end point, as we limped across our final intersection into Magnolia Park, that another team popped out of the side street twenty yards ahead of us. Three big guys—even then I didn’t put it together—and they looked fresh as daisies. I even said to Irish confidently, “These dudes must be doing the 26 mile course. There’s no way they did 50 miles and still look that good.” But sure enough, they did. They reported to Cadre DS’s table still twenty yards ahead of us, and we claimed third and fourth place respectively. It was only much later that they I pieced it together: these were the The Runners. We’d been shadowing them all night, not as closely as the French team kept on top of us, but one of them had gotten hurt sometime during the morning and so we got on their heels and stayed there. That was an honor: when we’d glimpsed The Runners in the middle of the night, they had seemed more like heroes out of Valhalla than real people. And yet without ever knowing it, we hung with them.
The finish line was still sleepy, almost anti-climactic when we got there. It was still much too early. We arrived together with The Runners, both at 16 hours and 48 minutes, to find only four guys lying in the grass drinking beer. The second-place guys had come in 20 minutes before us, our crew told us. Then they pointed us to a pair of normal-looking young dads in Hawaiian shirts. These were the first-place finishers, who had crushed the course in under 15 hours. I’d expected the Night King and a pair of direwolves. Instead, hanging out with their wives, with kids crawling on top of them, they looked like suburban dads who’d just mowed the lawn and come to the park to grill hot dogs with their families. However, when I looked at their Instagram page, I saw Dad #1 in an army uniform with a chest full of decorations, including jump wings and what looked like a Combat Infantry Badge, and in the park someone said something about Rangers. #everyday badasses

Redemption was sweet. A week after my second Star Course—my second in three weeks—I am almost back to normal. My ankles took a pounding from walking on concrete, which must be the worst surface possible except for lava, but when I met the semester’s new crop of students on Monday morning, I held onto my lectern and stood stable and upright enough that no one thought I’d had whiskey for breakfast.
And speaking of whiskey, Irish and I are putting out feelers for a new event for the Dream Team. Something where Lean Solid Girl and Lady Irish can do all the thinking and navigating for us leverage their logistical genius to the max. Something without concrete.
I met The Jolly Irishman minutes into my first GORUCK event, at kissing distance. We were all told to pair up: one person would bear walk across the beach and tow the other, who lay supine and clutched him around the neck. I ended up as a “top” with Irish as my “bottom.” Not having been in this situation with a muscular man since high school wrestling, I dispelled the awkwardness I felt by promising to buy him dinner and flowers next time. But Irish is a permanently grinning barman and adventurer who could instantly form a bond of friendship with a pit viper or a kraken. No ice breaker was necessary.
Irish proved indestructible and unflappably fun through that long night of smoke sessions and sandbags. After surf torture I was a quivering shambles, but Irish was still chuckling, calmly helping people, and having the time of his life. And the message he broadcast implicitly was, “This sucks, but you’re up to it physically, so let go and laugh at the absurdity! Across the street some lonely financial planner is watching TV in his $2 million living room, and you’ve chosen to fireman carry a Filipino school teacher with sand in your nostrils! Trust me, this is awesome!”
At every GORUCK event, I’m reminded of a fragment from Heraclitus: “Out of every hundred men, ten shouldn’t even be there, eighty are just targets, and nine are the real fighters … But the one, one is a warrior, and he will bring the others back.” Apparently Heraclitus did a Heavy or two, because late in the game there’s always one person who undertakes the heaviest lifting and also shows irrepressible good cheer.
Thus it was that when I first contemplated doing the Star Course, my top choice for a battle buddy was The Jolly Irishman. After blowing it in San Francisco three weeks before, I wanted redemption and I would not risk the slightest chance of another failure. There are only two people I could confidently call a 100% certainty for success, and of those two the Irishman was Numero Uno. He’s incapable of quitting and I knew he’d keep walking for just as long as his legs were attached.
The question was what we would do for logistical support. Unlike other GORUCK Challenges, on a Star Course you can stop to buy food and water whenever you please. But this takes time—it’s more efficient if someone brings it to you. And more fun! It’s also more efficient if you don’t have to carry all of your just-in-case items on your back, things like rain gear, spare batteries, spare socks, baby wipes, and other essentials. And there’s no better feeling than taking out your whole hydration bladder and letting the crew car schlep it to the next waypoint! Three liters of water weighs 6.6 pounds!
Following my failed Star Course, I anatomized my wrong decisions with Lean Solid Girl, who has Napoleon’s level of logistical mentality. We worked out theories about how best to “crew” (i.e. run a support crew) efficiently and safely, and we theorized that ideally the crew needs two people.
Irish and I began asking around for one or two jockish college students we could hire to make supply drops. I even briefly contemplated what might happen if we attempted a Grub Hub order for samosas and mango lassis with instructions like “Just leave it in the parking lot at Mercerdale Park. Try to hang it from a tree branch so the racoons don’t get it.” Instead, we got the Dream Team: Lean Solid Girl volunteered to fly to Seattle on the weekend before we started our teaching semester to (wo)man the crew car, and Lady Irish did the same! This illustrates why it makes terrific sense for athletes to couple up with other athletes. Lean Solid Girl did a 50-miler long before I did, and marathons too, and she gets into projects that any “normie” would dismiss as a quixotic death march, and she is actually interested in crewing such a thing, which goes so far above and beyond the call of duty that it deserves some kind of GORUCK Medal of Honor.
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 40to 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.
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
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
Russian training methods and Russian sports science. Raise your hand if you (a) love these things but (b) don’t read Russian. Then you probably owe almost everything you know to Pavel Tsatsouline, THE great interpreter of that subject and almost the most influential voice in American exercise. Pavel created an appetite for English-language popularizations of Russian training research much greater than any one man can satisfy, even a pedagogical genius like Pavel. Today guest author “Dr. Smet,” a Russian-educated physician practicing abroad, takes us behind the curtain of Pavel’s latest book for a direct look at some of its source material. Dr. Smet’s blog Girevoy Sport After 40is required reading for lean solid dogs, lazy badasses,and grapplers and kettlebell competitors.He has graciously allowed me to cross-post his original piece.-Dog in Chief
Pavel Tsatsouline has finally published his long-awaited book on endurance training, the Quick and the Dead. Despite the hype, in the end I was underwhelmed. Don’t get me wrong: the book has useful information but, as it makes clear on the last page, it is a long infomercial for the StrongFirst Strong Endurance seminar.
The material in the book is based on the research of a few Russian sport scientists and coaches, most notably Victor Selouyanov, previously mentioned in my blog [Girevoy Sport After 40 -ed.] in the post “The Heart is not a Machine.” Selouyanov was a bit of a renegade, and because of disagreements with the science establishment he never completed his doctorate. Nevertheless, his contribution to the understanding of training endurance was invaluable, and Russian sports science is still bitterly divided between his followers and opponents.
Selouyanov wrote several books, among them two that are of interest to me: Physical Preparation of Grapplers and The Development of Local Muscular Endurance in Cyclical Sports. Both deal with endurance, and Selouyanov’s concepts allow a systematic approach to training endurance in pretty much any sport. I will briefly and loosely summarize the most relevant parts of the book for grapplers (my current love).
From practical point of view Selouyanov was talking about two distinct groups of muscle fibers: glycolytic and oxidative. Glycolitic muscles are capable of producing great force, but because they are not very good users of oxygen they get tired quickly – in a few seconds – and are not very useful for activity that requires endurance. Oxidative fibers, on the other hand, do not produce as much force, but are virtually impossible to fatigue in aerobic conditions. Their power production drops from maximal to about 80% and stays there for a long time.
What gets oxidative muscle fibers at the end is the accumulation of lactic acid and, more precisely, hydrogen ions and the resulting acidosis. It happens if the production of lactate exceeds its elimination, which happens when you demand too much work from your muscles.
Oxidative muscles are good users of oxygen because of large number of mitochondria in them. Mitochondria are “power stations” of the cell where oxidation – the reaction between various substrates and oxygen – occurs, which results in the regeneration of ATP, the fuel that feeds the muscle fiber and allows it to contract.
Therefore, in order to develop endurance you have to do two things: build myofibrills (units of which muscle fibers are composed) and build mitochondria around them.
Classification of training loads based on long term adaptation
Methods of training are aimed at changing the structure of muscle fibers in the skeletal and myocardial muscle, as well as other systems (endocrine, for example). Every method is determined by several parameters that reflect the external features of a given activity: intensity of contraction, intensity of exercise, duration (repetition, series of the actual duration of exercise), rest interval and the number of sets or series (explained later). Each method activates internal processes which reflect immediate biochemical and physiological effects of a given training method. The final result is long term adaptation, which is the actual goal of using a particular training method.
For the sake of brevity I won’t spend much time on the internal processes elicited by each training method. I assume everyone reading this is a practitioner and is more interested in the description of the method and the long term adaptation it causes.
And so the methods are classified as follows.
1. EXERCISES OF MAXIMAL POWER
Intensity of contraction – 90 – 100%
Intensity of exercise – 10 – 100%.
Barbell squats and bench press, for example, are activities with low intensity of exercise, but high intensity of muscle contraction. Throws performed with the wrestling dummy in high tempo and low rest intervals is the example of high intensity of both muscular contraction and exercise.
Duration – usually short
Strength exercises are usually done for 1 – 4 repetitions
Speed-strength activity – up to 10 reps
Speed exercises – 4 – 10 seconds
Rest intervals – depends:
For strength exercises – 3 – 5 minutes
Speed-strength exercises – 2 – 3 minutes
Speed exercises – 45 – 60 seconds
Number of series/sets depends on the goals.
So called “developing” sessions use 10 – 40 sets
Weekly frequency depends on the goals.
If the goal is to develop myofibrills in the muscle fiber the series is performed to failure
If the goal is to develop mitochondria the series are performed to light fatigue
You just witnessed a fairly common phenomenon seen in Russian literature: the discordance of content and the title. This is exactly how it is in the text: weekly frequency – to failure or not, depending etc. It doesn’t make sense, I know, but we will have to forgive the good professor. – Smet.
Long term adaptation.
If performed to failure, this method leads to the increase of myofibrills in glycolytic and intermediate muscle fibers
If done to mild fatigue – leads to the increased phosphorylation in glycolytic and intermediate fibers, eventually leading to the increase in mitochondria
2. EXERCISES OF NEAR MAXIMAL POWER
intensity of muscular contraction – 70 – 90%
intensity of exercise – 10 – 90%
Example – barbell squat or bench press done for more than 12 repetitions
If you increase the tempo of exercise and reduce the periods of contraction and relaxation of muscles, you turn these exercises into speed-strength type. Examples include jumping and throwing wrestling dummies
generally 20 – 50 seconds
strength exercise are performed for more than 12 reps
speed strength exercises – 10 – 20 reps
speed exercises – 10 – 50 seconds
for strength exercises – more than 5 minutes
speed-strength activities – 2 – 3 minutes
speed activities – 2 – 9 minutes
This method is aimed at increasing the power of anaerobic glycolysis
Currently there are no publications that demonstrate positive effect of near maximal exercises performed to failure.
However, numerous studies show deleterious effects from this type of exercise.
Long term adaptation:
most effective for increasing myofibrilles in glycolytic muscle fibers
no increase in mitochondria
If terminated well before failure or performed with pauses, this method leads to the development of mitochondria in glycolitic and intermediate fibers: there is no excessive acidosis in the muscle cell, and lactic acid is eliminated during rest.
There is a method used by Russian athletes, called 10×10. An example in the video below:
The session consists of three exercises: pushups, jumps and pullups, all done for 10 reps in a circuit, for ten rounds, the intensity – about 80%. As you can see, the athlete never comes close to failure, and each rep is follower by a short rest – which gives the muscles a chance to get rid of lactic acid and avoid acidosis. This is the example of near maximal training without destroying the body. The coach recommends starting with lower rounds and building up gradually.
To prepare for the Seattle Star Course, I’ve been playing with topo maps, Google Maps, and Road Warrior, feeding them different scenarios, and here’s what I’ve concluded: 1) Plan with Road Warrior, but don’t walk with it. As far as I can tell, Road Warrior is really designed for delivery drivers. It’s great for driving on errands in the most efficient order. But when you choose this path or that path to walk to your next point, you’re stretching Road Warrior outside of what it’s designed for. Despite its “walking” mode, it thinks you’re a very slow car and cares nothing about elevation. I fed it scenarios in Seattle and it always dictates the straightest possible line, even up steep slopes, and even when a flatter alternative exists. (Example: In one scenario, instead of a 2.4-mile route with only 100 ft of climb, it chose the more direct 2.3-mile path that climbs almost 400 feet!) 2) Walk with Google Maps on CYCLING mode: Cyclists terrify me on the winding rural highways near my home, where once a year I whizz around a turn at 55mph and suddenly have a near-death encounter with a slow-moving peloton. But DAMN they get things done in Silicon Valley! Because even though Google Maps shows decent awareness of elevation when you ask for directions in walking mode, it rocks at avoiding climbs in cycling mode. Here’s an example: It suggests three routes: 2.2 miles and a 285-ft climb; 2.3 miles and a 108-ft climb; or 2.7 miles and a 49-ft climb. And no traffic either.
In a side bar they provide a graph comparing the climbs:
You still need Road Warrior (or a comparable app) because Google Maps can’t handle your “hit list” of a dozen-plus waypoints. But I’d say that after you order the points in the optimal sequence, you can pretty much leave Road Warrior alone and just glance at it occasionally to reacquaint yourself with the bigger picture. But speaking of the bigger picture…
3) Paper maps. I’m going to use my paper map(s) more. When I’m tired or busy, I want to look at something bigger than my index card-sized phone screen, and whose scale doesn’t zoom in and out to the point of disorientation. And if I have time during halts, I’ll pencil in our macro-level route plan so we’ll have a tangible depiction of our progress through the course.
