The map or the territory pt 3

Simplicity is the ultimate sophistication.

Leonardo da Vinci

In the first article of this series I explored the risks of assuming that there is something fundamental beneath the surface, which must first be optimized in order to increase performance later on. In the second article I challenged the need to continually increase physical training load, suggesting to focus instead on adaptation of task difficulty to where our athletes are exactly now. 

In this last article of the series we will continue to explore methods to stay in the present, and how the use of our language can help but also overthrow our attention to what is really going on and hinder the transfer of the exercises we prescribe.

As we have seen, the promise of the ideal is repeated over and over again but never fulfilled. When technology was invented to measure oxygen consumption, blood lactate concentrations and force it gave rise to new models for training. Now the recent ability to sequence DNA is looking to change the way we measure and prescribe training.

While this way of looking at the internal processes of the body certainly has merits to many sciences, it is still not able to add much to the decision process constructing training programs. Just like with the preceding reductionist approaches comes the same possible pitfalls. 

We could also measure the length of fascicles, concentrations or flux of chemicals, energy storage or the efficiency of the electron transport chain and… Well, it’s likely to be a mess to bring all those parts together in a general capacity. The whole is not the sum of its parts, despite how magnified they may be.

The aspects of things that are most important to us are hidden not because of their depth, but because of their simplicity and familiarity.

The philosopher Ludwig Wittgenstein once described the situation as it is as if a man is standing in a room facing a wall on which are painted a number of dummy doors. Wanting to get out, he would fumblingly try to open them, vainly trying them all, one after the other, over and over again. But, of course, it is quite useless. All the time, although he doesn’t realize it, there is a real door in the wall behind his back, and all he has to do is to turn around and open it.

Having explanatory models of how it all works, seems to be helping us to take the right actions. But the problem with the concept creation is that it assumes that by creating concepts, we can lay down in advance what it is we are thinking about. In plain English, there is really not much evidence supporting the theoretical concepts of phase potentiation, but we have a hard time to see this since it is all we know.

To help our man get out of the room all we have to do is make him look in a different direction. To do this we should turn things around, away from the safety of dogma, and look at what is hidden in plain sight.When do our athletes struggle in racing or during competition? Describe those situations without explaining why they happen.

This brings us to the topic of terminology, on how to best communicate with the people we coach.

Concept language is used to describe words or constructs that bundle a lot of actions and interactions under a simple word. To transmit less detail and more fundamental aspects of information faster and easier, mainly by experts of a defined field.

Complementary training, meaning all training carried out away from the field of the game, with the intention of helping successful execution of skills in the game itself (or a more functional life for that matter).

Coaches, specifically us who provide help with complementary training, are usually using the concept language of our field, as opposed to the language of the game itself. We use constructs that are natural in the gym, like “strength”, “strength endurance” and “speed”. We speak a language of “intensity”, “volume”, “sets” and “reps” with the athletes that we train.

When athletes are new to complementary training they usually struggle. They have a hard time to understand our lingo and to perform the training we prescribe with it. When we invite athletes into this world, filled with new mysteries to solve, they will eventually get better and better at speaking our language and doing our type of training.

But this was never the end goal.

It is not enough to show how clever we are by showing how obscure everything is

J.L. Austin

There is some evidence that memories are stored in the same brain regions as they are perceived. This means that not only what you mean when you phrase your coaching cues matter, but also how the athlete interprets them and in what context the training is carried out for their subsequent retrieval.

The way language seems to provide a gateway into athletes’ motor cortex is quite stunning. Studies show that when participants hear verbs like lick, pick and kick it activates the respective brain regions of the tongue, arms or legs.

By using language so different from the field of play, we might accidentally be creating a rift between the athletes training and the application of it. By using our concepts instead of mapping into the common language that is better understood by our trainees we are limiting the transferability of the training they do .

Sports is a practical matter. It is not about words, but rather about actions. Action language, on the contrary from concept language, is the language used to describe only relevant details in a clear, concise and objective way, transferring details without judgement, often with a more direct purpose. It tells what to do in a specific situation of a game.

When we start with what we see, rather than from physiological constructs, we are more likely to be able to create terminology that ties the action language of the sport and concepts of exercise science together. Then we can utilize this terminology in a coaching process that is individualized without becoming abstract.

The athletes will perform their exercises more purposeful and they will intuitively know how to use the skills they are strengthening. And, although they might not be well versed in your world, they often are very knowledgeable of their sport. They know themselves and they will be able to help improve those exercises in a constructive way.

In this the third series we will show how one could implement the proposed methods by using cycling sprinters as the example.

A muscle fiber generates tension through cross-bridges of actin and myosin. Under tension, the muscle can be made to lengthen, shorten, or remain the same. Muscles also have elastic properties where energy can be stored to increase force, but only for a very short time. When a muscle is not tense it is “slack”. To produce movement, that slack has to be removed by pretensioning.

At high speed and high power the demands for contraction velocity, pretensioning and efficiency of storage, and return of energy are greatly increased. As a result there is little positive transfer between different types of muscle contraction. In cycling most muscle actions are shortening contractions.

Cyclists produce higher peak pedal power and rate of force development on a stable cycle, commonly referenced to as an ergometer (like a watt bike, a spinning bike or a trainer) than when riding in a velodrome.

When sprinting on the ergometer, the riders only have to focus on producing maximum power, whereas on a bicycle they also have to control the direction and stability whilst trying to produce maximal power. Also, one of the biggest factor to overcome during cycling in aerodynamic drag which is not easily simulated in a gym.

Because of different demands there is an altered riding position observable as difference in hip, knee and ankle angles.

With the principle of specificity in mind there would seem to be arguments for the the track cyclist to train on the track, or to find other ways to challenge stability if that is not possible.

Torque-pedaling rate and power-pedaling rate relationships for laboratory and field tests, estimating “optimal cadence” in Elite track sprint cyclists (Gardner et al, 2005)

Cadence, or pedaling rate, is an important factor influencing the economy of motion, power output and the development of fatigue during cycling. In track sprinting the use of fixed gearing makes this a very important consideration at race day, but also to guide training. The inability to select the best gear for specific situations during a race, forces a decision on which gear would be overall most suitable for a rider in all situations. Some factors influencing this are the type of race, the opponent and the rider himself.

Bigger gears give the opportunity for higher maximum speed with less fatigue. If one is able to get up to speed and then to effectively spin it around, that is. With higher inertia comes higher demands of force.

There has been considerable research in what is called optimal cadence, the cadence where peak power is achieved. Given the importance of contraction velocity and efficiency in high speed and high power movement it is thought to provide important insight in the selection of pedaling rate, and therefore appropriate gearing.

Optimal cadence is highly correlated with the amount of fast-twitch muscle fibers, and in a sport where the ability to push bigger gears are so rewarded as it is in track cycling, there is likely not much drawback in continually training to increase their proportion. Given the low risk of gaining mass when doing large volumes of training, there is little reason for the road sprint cyclist to think differently.

As with other constructs there is a catch to letting peak power testing dictate training decisions. Those tests are almost always carried out with very little pre fatigue and from a stand still or low cadence. Following periods of exertion cadence at peak power has been shown to change. Higher velocity provides less time for cross bridges to form, and therefore the demands for the speed of contraction increases. The demands of the athlete shift with each situation and each athlete.

You can’t make an omelette without breaking some eggs…?

In a small country like Sweden, with a limited talent pool even in our national sports (football, ice hockey, skiing), we need to adapt our coaching to improve each person in front of us, rather than the other way around.

One would need to look at the specific situations each athlete struggles with to best construct exercises to increase their capacity in those situations.

Sven Westergren is the current Master national champion in Match sprinting. Match sprinting is the discipline where two opponents go head to head for 3 laps, or 750 meters. He is big and strong and able to push bigger gears than his smaller opponents. They however have the upper hand when it comes to quick bursts of acceleration from lower speed.

Tactics comes down to controlling the pace. If Sven is able to keep the base speed high enough to prevent aggressive “jumps” from his opponents they tire quickly, and have little to do when he eventually accelerates to top speed. In order to strengthen his ability to do so, exercises for acceleration and maximum speed can be constructed to involve a build-up beforehand.

With little access to the only Velodrome in Sweden, which is located more than 2 hours drive from where we live, and knowing that the transfer of skill development from ergometers to the track might be low, we do most of our training during winter season on resisted rollers. This is not ideal, but better than other options.

Rollers might provide less physiological overload, because their larger demands for creating stability. Peak force and power are lower than on an ergometer, but quite similar to the track, and we have seen more transfer of improvements on to the track because of this.

We should use our coaches’ eyes when we construct exercises for our athletes, but if we can formulate them with language well understood by our athletes, we are improving both their transferability and the chance for better feedback. A clear goal for our exercises also allows for better judging if the exercise was successfully executed and functional.

A possible way to create a helpful terminology would be to first define a game model based on the broad actions taken in their sport.

For track cyclists we could construct such a model by going through each broad component carried out in a race. A very simple example would be to specify the possible actions to master as the start, the acceleration, maximal speed and speed endurance.

For each of these areas we can assign suitable actions, which would be a good starting point in order to create a more individual and usable “dialect” of a general sports language. Actions however do take place within the boundaries of space and time. If we sat down in a car and all everything that was told to us was to “drive” the action would seem less connected to its environment than if we were also given instructions on how fast and in which direction.

Similarly our cues will also benefit from the inclusion of direction and distance.

Christoffer Eriksson is the Nordic Champion in Keirin. Keirin is an event similar to the match sprint but features between three and seven riders competing in a sprint race of 3 laps after having followed in the slipstream of a pacing motorbike for 3 laps. The motorbike gradually increases in speed before peeling off and letting the sprinters battle it out.  The event is fierce, fast and unpredictable, with many split-second decisions about when to hold and when to attack that have to be made under fatigue.

Christoffer has lower top speed than many of his opponents, but on the flipside he is perceptive and he does not tire easily. In competition he cannot just muscle himself to wins but instead has to see how the match unfolds. He wins by finding the opportunity to get a gap early, or to follow the strongest riders when they do so. Using his strength to not get boxed in, and accelerate to fill gaps is an important quality for him.

One exercise to practice this ability could be to build, then simulate staying on a wheel, relaxing to get some distance in order to use the slipstream to get enough speed to go past on the outside. We could call this exercise “hit, fly, hit”.

In order to build the language for this we should consider the actions involved in it. Most important is the verb that should be the main descriptions of the action to take. I’ve often used the word “push”, as it is pushing the pedal away we would like the athlete to do. But considering that pushing is something that could be done slow I prefer “punch”, which I think would be a perfectly fine option. You can push slowly, but you can’t imagine punching slowly.

Knowing about the very specific encoding of memory storage, I would like to use a word less associated with the upper body. I would propose using “stomp”, which would seem as a similar action as punching, but for the lower body, where power is most important for cycling.

When describing the exercise, I would use something like “Build up to speed and and then stomp as hard as you can to go faster, closing the distance to a breakaway rider. Then stay as smooth and effortless but without losing cadence, and then again stomp hard to accelerate past”.

In order to sharpen the action cue I prefer to shorten it to a minimum. Keep the action, direction and distance, and end up with “stomp fast forward”, and after the “fly part” again tell Christoffer to “stomp hard past”.

The exercise will be tied to race tactics, and we would be able to get a nice feedback loop going in order to improve future exercise according to the needs and skill level of the rider.

The skeptic could point out that the examples given in this series of articles appear to be quite simple. That all I do is to observe my athletes, and when I think I’ve seen what needs to be improved upon, I have them do that very thing. Yes, with some variation, and sure, carefully considering communication and possible improvements of the exercises – it all appears to be so simple.

They would certainly be right. Even though I would argue that doing the simple thing well, is not easy. Let’s also describe how one could use the same methods to develop something less like what is performed in the sport itself.

When an exercise is very specific, by definition it has a low degree of overload. If we would like to lift the middle of a rug from the floor, we would do best to direct most of our lifting to that point exactly. If we want to maximize how high we could get it, we would also benefit from at the same time lifting at the edges.

In elite sports, you rarely win with the distance of a landslide. More often with the small margins visible in the loser’s sigh. The athlete also needs the marginal gains found in general overload.

You have to appreciate the impact that variation and change has on how an athlete reacts to training across the board

Derek Evely

The upper body is involved at a remarkable extent when cycling hard compared to when cycling less hard. The degree of negative relation between upper body asymmetry and maximum cycling power production is quite exceptional.

This should not come as a surprise – in high intensity movement the opposing forces are so great that muscle fibers have to stay close to their optimum length, and as the feet are attached to the pedals, there is less flexibility of positions in the lower body. One can imagine how much this must challenge the trunk and the pelvis when force is applied into the pedals. Studies also indicate that compromised coordinative patterns for the ankle joint correlates with loss of power.

For the cyclist who wishes to win in a sprint this would seem to make an argument for

  • Upper body training (Pullups and Dips?)
  • Hip strengthening (Hip thrusts seem to be popular)
  • Core training (oh, those circuits that burn so good)
  • Ankle strengthening (Calf Raises, for more of that sweet burning sensation!).

While there is nothing wrong with these exercises, I would treat such isolation as things we do at the end of the session, after we’ve done everything else.

In movement, force produced by muscles moves through the body. Patterns between muscles occur with the changing demands of force in order to develop synergies. The whole body efficiently forms a unit capable of more force production than any of its muscles in isolation.

Again, with the principle of specificity in mind, there seems to be an argument for multi-joint compound movements in the gym to maximize transferability of increases of strength.

The need for variation is fulfilled already if we make sure that there is a large extent of overload.

“The human race shouldn’t have all its eggs in one basket, or on one planet. Let’s hope we can avoid dropping the basket until we have spread the load.”

Stephen Hawking

In bicycle sprinting you need to subdue very heavy resistance, especially in starts and acceleration. Further, these efforts must not make you so tired that you can continue to turn around those heavy gears the distance required to complete the race. Being strong for the sprinter is very specific.

In some of its disciplines, like in the match sprint and Keirin, a modernization of tactics has raised the need for top speed over acceleration. This has forced the riders into an arms race for the capacity to push bigger and bigger gears.

In earlier posts we have explored the balance between specificity and overload in the gym setting, and isolated the following basic rules

  1. Keep movement somewhat similar in movement patterns and stimuli
  2. Overload as much as possible while satisfying rule #1. Large load means larger neural adaptation and higher percentage of muscle fibers being recruited.
  3. And do not let the main movement mechanics break down or change during the set

I argued for single leg movements for developing maximal leg strength for sports played on one leg (cycling, team sports, track and field, racket sports, etc) and double leg movements for those that have movements performed symmetrically (powerlifting, weightlifting, CrossFit, etc).

Possibly we could tweak this even further.

Before we go on to explore this I’d like to point out that I do not propose to exclude single joint general movement, despite having less obvious benefit. In fact I have all of my athletes do such movements, like pull-ups and dips, but they do it late in the session, after the more contextual work is done.

The way our muscles in the lower body are structured allows for a unique role in the transformation of rotation in the knee joint into the production of high force. Biarticular muscles are muscles that cross two joints rather than just one, such as the hamstrings which cross both the hip and the knee. Rectus Femoris in our quadriceps and gastrocnemius in our calves also have this property.

These bi-articular characteristics allow for extending the joints one by one in a sequence called the proximal-to-distal sequence more commonly referenced as triple extension. Extension of these joints one by one allows at least one of them to have a favorable translation relationship throughout the full extension.

This sequence allows for the possibility of more net force production, but in order to function properly the extensions should be completed in a certain order.

An ankle collapsing during the pedal push does not translate into movement of the pedal, but still cost energy. To prevent this leakage of force efficient cycling pedaling depends upon the ability to keep the ankle locked into position.

If the push downwards is done with a highly extended or flexed ankle the extension movement becomes rapidly less efficient. It would seem that cycling therefore cannot fully use the benefits of the triple extension.

During the sprint, ankle joint power decreases more rapidly than power at other lower limb joints, while hip extensors and knee flexors sustain their power for a longer time at higher rate.

The hip extensors are also the strongest muscle group in all velocities, followed by knee extensors and hip flexors. The weakest muscle group are the ankle flexors.

This seems to further support that there are differences in the efficiency of the pushing sequence with fast cycling, possibly at least partly as a result of not being able to execute the triple extension in the most efficient sequence.

Road cycling too involve recurrent demand for high force output, with little possibilities for perfect execution of the the proximal-to-distal sequence

New inventions in technology to measure performance in endurance training changes the way training is conducted and planned. The way things work in the strength world is no different. Traditionally the measurement was the weight on the bar, but lately bar speed, or power, has been popularized as a way to monitor performance.

More contextual always means less optimal for overload, meaning that athletes will always have lower numbers to show for their efforts. The systemized way of using such constructs could potentially bias us to high performance in these constructs, rather than to look for more contextual performance increases.

It will also subconsciously nudge us toward movements with the highest efficiency, regardless if we do not have these options for movement execution on the field. This is often defended with references to higher neural stimuli of these exercises. High effort in more contextual movements will also have equally high neural stimuli, despite lower measurements, as an effect of their lower mechanical efficiency.

Very seldom do we train strength in the gym with our joints in such non-optimal positions. Since muscles do change their optimal length and other properties with exposure, this is the whole point of strength training, and given that the coordination of chains of muscle is no less trainable – maybe we should?

The standing start is no different from seated pedaling. If the knee joint and hip joint creates force by opening up, the ankle must stay fixated in order to translate this force from above into the pedal. If it does not there is a leakage of force.

As we found in an earlier article the split squat is a fine example of an exercise capable of generating a lot of force. Even more so with the added stability of the hands. We can see that the ability to transfer force through the ankle is one limiting factor in the video of the standing start above.

Possibly we could try to combine a dynamic high force output from the hips and the knee joints with a static high force demand of the ankle?

As cadence increases, the time we have to create force shorten.

Disregarding exactly what the optimal pedaling rate for high power sprinting is, it is definitely high enough to not allow for inefficiency. For us to develop efficiency to perform unloaded high intensity movements, we should practice pre-tensioning with the use of co-contracting muscles alone.

This could be done with high power ballistics movements, such as jumps, especially from static positions with the least possible help from pre-loading and counter movements. I see few drawbacks doing some of them from mechanically challenged positions similar to what you would find in bicycling.

The splinter in your eye is the best magnifying-glass.

Theodor W. Adorno

The main reason we still lean so much on these perfect systems of explanation for decision making is that they provide the false safety of the ideal. Numbers are clear and concise, actual situations are messy. But in that mess there is also information that is lost when quantified.

A magnifying glass quantifies and enlarges an image, but the spectator cannot truly construe meaning from what is magnified. Only when we get a “splinter in our eye” we are forced to stop to regard the things that do not fit in. The flaw in vision, becomes a way of seeing better.

To say something about particular situations risks exposing our ignorance. Our challenge then, becomes not to hide from our possible ignorance, but to embrace that risk.

CrossFit Exercise selection Skill training Strength training The map or the territory Training theory

The map or the territory pt 2

In the realm of sports science what can be thought of as classical periodization was originally discussed by Russian scientist Leo Matveyev and further expanded upon by Stone and Bompa. Periodization is a logical method of organizing training into sequential phases and cyclical time periods in order to increase the potential for achieving specific performance goals. All while minimizing the potential for overtraining.

Phase Potentiation is the strategic sequencing of programming phases to increase the potential of subsequent phases and to increase long term adaptive potential. Theoretically, using this concept, peak performance occurs in a controlled way as the phases are stacked on top of each other.

When examining the success of classical periodization concepts they fail to convince of their superiority over more concurrent approaches to the planning of training.

Not only are these long detailed and rigid plans vulnerable to unplanned periods of non-training – what do we do when the athlete gets ill? – but also that we just miss our mark, either on the resources available for training, or the speed of progress we ended up with. As we are working under either of the two false assumptions that averaged group-based trends accurately reflect likely individual responses, or that the individual response can be extrapolated to work for a group – our plan will only provide a false sense of security.

These methods with long cycles of mostly general work are also quite time consuming. For most sports disciplines, the packed competition schedule makes it difficult for coaches to adopt them, as there is simply not enough time during the season to improve poor form.

However, the most important drawback is their very low rates of effectiveness. When scientists have looked at the amount of athletes who are achieving the season’s best result at the seasons most important events, like World championships and Olympic games, the results are disheartening. Seldom if ever more than 1/4th of the athletes manage to deliver their top results for that season.

The theoretical and speculative “delayed training effect” concept assumes that training basic capacities at earlier phases of the training plan has positive effects on actual performance long after they are taken out of the training programs, replaced by more sport specific exercises. They also produce unwanted adaptations, such as significant decreases in power and speed abilities. Coaches might ask themselves whether basic training is a real basis for competitive performance, or whether it is a loss of precious time to athletes.

To be fair, basic training is not only done for peak performance but also for the sake of injury prevention. There is also plenty of evidence suggesting that what is likely responsible for a large proportion of non-contact, soft-tissue injuries is not training load as such, but rather excessive and rapid increases of them.

It is likely that the positive adaptations in muscles and tendons provided by longer periods of basic training may also be obtained by typical strength and power exercises. Exercises which can be implemented with little to no negative effects during the course of the season.

The stakes of unsuccessful performance at key competitions are high, with evidence suggesting that more severe psychological consequences are a distinct possibility. Failure to meet performance expectations include anxiety, interpersonal hypersensitivity and coach-athlete relationships falling apart.

“Speed is the most precious thing in swimming. It is what it is all about. I do not understand why you would spend weeks and months not training speed, then hoping it will come back when you taper and race. I believe you must always be within one second of your personal best time at all times of the year. That you must train for speed all year round. That your sprinters must sprint often and race regularly throughout the year.”

Gennadi Touretski

In the 90s the “Speed through Endurance” philosophy that reigned supreme in Australian swimming was challenged by the Russian coach Gennadi Touretski. This “more is more” philosophy was to work hard to first develop an aerobic base for 10 to 16 weeks (or even longer!), then to significantly reduce training volume close to the competition. The idea was that the more you swim, the more efficient you become and the more efficient you are the faster you can swim.

Touretski, the coach of one of the sports all time greats, Alexander Popov, was recruited to rejuvenate Australian swimming after a poor Olympic result and he did so by removing the (imaginary) certainty of linear adaptations provided by a base training phase.

He warned to assume speed will return once it is lost, and was wise doing so. The “delayed training effect” is not completely supported either by science or practice and its use as a tool to improve actual results are very unpredictable. There is simply not much basis to sustain the idea that the body is ordered into basic and specific capacities and that the overloading of a given basic capacity will suddenly “supercompensate” later in the training cycle.

When you have a capacity, you can certainly lose it (and haven’t we all experienced that). But that risk is way lower than the hope for you to gain a completely new capacity at a later point in time. For that reason he included speed training at all times of the training program, throughout all of the year.

“I think coaches do too many drills. Drills do not improve technique. They teach the basic movements of the stroke. To improve technique you must work with the individual swimmer, over a range of speeds, from slow to race speed and give them constant feedback about their technique, talk to them about how it feels and help them to develop their own technique. Every swimmer is different – every technique is different.”

Gennadi Touretski

Instead of general drills he believed that technique is a personal thing, and that training prescription should not be about doing a lot of general drills. Rather it should be about optimizing the technical efficiency of the stroke of the individual swimmer. Start with what you see, and practice what you see is needed for that particular athlete.

He would walk with his swimmers continuously throughout the session, ask them to swim initially at a slow speed, then have them progressively increase speed until he would notice a technique inefficiency. He would then describe rather than explain what happened and then figure out a cue to address the inefficiency he had seen.

There is plenty of evidence to support that increasing the physical load of training in the form of exercise intensity, volume or duration can be successful in order to enhance training adaptations.

When looking for the optimal adaptation found at the upper limit of tolerance, we expose ourselves to very small safety-margins of error. The presence of deep uncertainties linked to working with human beings challenges decision making by questioning the robustness of all purportedly optimal solutions. Knowledge about historical adaptation yields little to no information about how our “optimal” solution performs if the future surprises us, and they do not guide us to solutions that might work well if the predicted future does not come to pass.

Physical load can only be increased so much, and often this “progressively do more, do harder”-philosophy eventually pushes athletes into injury. And regardless of the progress made before this, injuries put and end to all progress.

Traditional methods for decision making require agreement about the current and future conditions and only then to analyze our decision options.

In a paper published by the World Bank on developing new processes for decision making under deep uncertainty, the research group suggested that alternative methodologies can help in managing uncertainty. These methods start the other way around by stress-testing options under a wide range of plausible conditions. All without requiring us to agree on which conditions are more or less likely, and against a set of objectives.

In the context of sports performance the traditional methodology would be to construct a training plan by starting out estimating the future capacity, form and other factors. For example to predict how much a specific squat cycle would increase squat numbers, and how much that in turn would affect sport performance in specific numbers. Only after these predictions are made we would evaluate the possible upside and downside under these assumptions.

This is problematic on two levels. First, many important assumptions are buried in models, rather than in front of decision makers and therefore vulnerable to bias. Second, many factors are difficult, if not impossible, to predict and risk to cause a gridlock in the decision process. 

As an alternative, we could identify the plan that is robust, working well across all the scenarios by “stress-testing” our options under a wide range of plausible conditions. All without requiring us to decide or agree upon which conditions are more or less likely.

This means to imagine different outcomes from many possible methods. Squat numbers increasing by 15kg, 10kg, 5kg, staying the same or even regressing. Which methods end up with the highest satisfaction and lowest regret under all possible outcomes, including high or low transfer to sport performance?

When faced with the possibility of multiple outcomes we will end up choosing “no-regret” or “low-regret” decisions. Decisions on reduced time horizons that have high utility no matter what the future brings. They will be more reversible and flexible, and have larger safety-margins.

In order to learn a skill, like the strict muscle-up as shown in the video above for example, do we really have to increase the physical training load? Or could we limit explanation and predictions in order to concentrate on when our athletes struggle now in the skill.

Continuously challenging the individual participant by progressively increasing task difficulty during long-term motor practice enhances motor learning and optimizes performance. Such progressive long-term adaptation to individual skill level not only enhances learning, but does so without necessarily increasing either the volume or the intensity of training.

Simplicity is key both for scalability and to see what is actually driving the trend without the distraction of too many variables. Managing a program of only slight changes and frequent evaluations allows for it to be data driven (as trend analysis is time-sensitive and time-powered).

All of this seems to suggest to use different, not more and often but little-approaches rather than to speculate on theoretical basic capacities, then build a base and to expect linear adaptations.

The old “more is more” approach is still very much ingrained in our way of thinking and planning. That is quite obvious when one looks at and listen to coaches who would subscribe to these theories of learning, but often still feel obliged to offer a progression of physical overload throughout their athletes cycles. Change is quite hard.

Is this the perfect progression to learn or strengthen a skill? Certainly not!

If anything should be clear by now it is that there will always be cases that are different from all other cases. Every method has its place. 

I can also picture you thinking that, well, “those examples you have given are too easy. Sure, in strength sports you can get away with performing the specific skill, not something more basic or different, but simply overloaded at the level that the athlete is, but what about other sports not practiced with a barbell or a set of rings?”. Well, stay tuned for more examples of practical implementations of these principles in part 3.

I’ll leave you with the words of the great Touretski, who may have passed on last year, but whose actions and words hopefully will live on for long.

Dare to be different. Doing the same thing as everyone else is a doomed strategy and a flawed philosophy.

“In early life I thought of studying economics, but had found it too difficult!”

Max Planck

In order to optimize performance, training theory has followed it’s fellow scientific endeavors looking deeper and deeper into details of their fields of study in a search for more detailed models of the world. These models are thought to provide more insight into underlying factors of performance. By uncovering them we can then design more meaningful training interventions. This manifests itself in metaphors like “the man as a machine”.

Similar to what Sigmund Freud did in psychology, when he presented the idea that thoughts and emotions outside of our awareness continue to exert an influence on our behavior. Even though we are unconscious of these underlying influences, physiology too has focused on hidden thresholds and reduced causal models of explanation for performance. The hope is to create better and more stable athletes built “from the ground up” and upon more basic conditions for performance than what can be seen with the eye alone.

While this project certainly has merits, it can also obscure the vision from what is “hidden in plain sight”. When searching for what is within and by looking deeper behind what is apparent, you will lose sight of how a scientific area is connected to other scientific areas: how things “just work” in the common world. When one has dug a deep enough hole, he can no longer see over the edge.

Complex biological systems (nature, humans…) are characterized by the fact that they consist of lots of interconnected dependencies in the different parts of its whole. A system constantly exposed to both sensitivity and noise, and a system of constant change.

It’s also quite easy to get stuck in a loop of trying to uncover more and more of these underlying factors, rather than to carry on with whatever knowledge we already have at the moment.

Better than using a detailed map to navigate an ever-changing landscape, like a glacier, would be to routinely triangulate your position and endure living with the degree of inaccuracy and uncertainty that comes with not knowing exactly where you are. Even though the belief in the perfect map gives a sense of security, it is a false feeling that risks leaving us blind to what is actually happening.

Simply observing what we have in front of us is often hard to do.

In order to be able to compare efforts and athletes we usually take the leap from qualitative observation to quantitative data collection, and by doing so removing them further away from the context where they were observed. How do you quantify “fast” or “slow” or “hard” or “easy” without delimiting them by turning them into numbers? Numbers fit so much better in spreadsheets for statistical analysis.

Not only are we by doing so removing the effort out of its context, we are also risking to try to affect these new numbers rather than the situation they emerged in.

You don’t want your planes to get shot down by enemy fighters, so you armor them. More armor makes a plane heavier and heavier planes are less maneuverable. They also use more fuel. Armoring planes too much is a problem; armoring planes not enough is also a problem.

During the second world war the American army was studying the planes returning from battle and kept reinforcing the areas of the planes that had the highest number of bullet holes. However, more and more planes were lost despite their added protection.

This continued until the statistician Abraham Wald noted that the military only considered the aircraft that had survived their missions. Since they didn’t, or couldn’t, look at the specific battle situations where shots were fired, they failed to see the planes now rendered unavailable from assessment. Wald instead asked: where are there no bullet holes at all?

As aiming at moving planes is not that easy, especially in those times, he figured that the damage would have been spread quite equally all over the plane. Since this did not adhere to the observations, he was fairly sure he knew where the missing bullets were: on the missing planes.

The reason planes were coming back with fewer hits to the engine is that planes that got hit in the engine weren’t coming back. The armor, he said, shouldn’t go where the bullet holes are, but quite the opposite, where the bullet holes aren’t.

At the end they managed to logically figure out a way of protecting their planes. But all of this would have been quite clear if they had not only looked at the data, but also kept an eye on the actual action.

“Mathematics is the source of a wicked intellect that, while making man the lord of the earth, also makes him the slave of the machine.”

The technology to measure oxygen consumption first arose in the early 1920’s. Using that ability Hill and Lupton found that there appeared to be a maximum limit to oxygen consumption, when despite increases in speed, their VO2 consumption did not also increase any more.

After this most studies in exercise science have been evaluated on the resulting change in VO2max rather than actual performance (such as ability to stay with a breakout, handling of different sections of a race, movement form or even something simple as average speed over a distance). VO2max is less variable and more tolerant to changing conditions. It also happens to fit well into columns of spreadsheets.

As outcomes are increasingly measured by a specific construct, they start to shape the outcomes themselves. Researching training interventions using this or that variable as the standard of success, will slowly shift the training interventions to strengthen just that variable rather than something else. They become self-reinforcing as you will always find more of what you are looking for, and less of what you don’t. Even though that variable might have a very poor transfer on actual sports performance (or health for that matter).

Whenever a new parameter is discovered or introduced, a large degree of emphasis is put on that parameter in the research.

Several new ways of taking measurements of biological processes have had similar impact. With the ability to portably test lactate, research was centered on ways to improve lactate threshold. With the ability to measure force, other variables came into the limelight, such as Functional threshold power or Critical power.

If we all agreed on what math problem we were trying to solve, then we can sit down together and say, hey let’s calculate! But sport and life is messy. We might not agree on what we’re trying to optimize and we also have a lot of uncertainty about what the consequences of our actions will be. 

Even with access to great data, not everything’s an optimization problem. Ultimately it is crucial that we understand the limits of the technology we leveraged to help us to navigate our complex world and the values that often invisibly determine how we use it.

“For years we have seen study after study attempting to compartmentalize intensity domains based on an assumption that there is some physiological decompensation point. However we reach no clear consensus on this. First it was MLSS. Then VO2 kinetics. Then FTP and CP, but none are conclusive. Perhaps we are looking for something that isn’t there.”

Dr. Jeroen Swart

We are starting to see why Max Planck, awarded the Nobel Prize, once said that he saw economics as a harder discipline than his own field of theoretical physics: due to the inherent need for subjective judgments. Dealing with humans, is dealing with unpredictability. This could certainly be said about exercise science too.

We often think of these measurable physiological variables as clear cut, defined markers. We use them to train at different thresholds and to classify our training as such. We assume that the transition is clear and that these parameters represent some sort of boundary line, and that improving them leads to better performance.

All of the above mentioned concepts can be helpful, and used to organize and guide training but we need to understand that they do not by themselves represent increased performance. That they do not represent a clearly defined transition. Physiology is complex and messy.

There is no sport of highest VO2max, Critical Power or peak wattage. We should not be so in love with a measurement so that we forget to look at how an athlete handles specific situations of their sports.

”I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain.”

Roy Batty, “Blade Runner”

When you put a pot of liquid water on the stove it is in a steady state. All of the collective molecules exist in liquid form. As soon as you begin applying heat and pressure the state begins to change. At any given point in time we are unable to predict which molecules will make the transition. They exist at the edge of chaos. Provide enough heat and pressure and over time and they will eventually turn into a gas.

Complex systems, such as humans, have interesting properties. Strong interactions between their parts, feedback, emergence, self-organisation, adaptation, growth, change. None of these are a simple linear process. Large interventions in a variable does not necessarily have a large effect on the expected variable of interest. Similarly, a small intervention can have large and unexpected outcomes. Just like a “perfect storm” – a combination of circumstances drastically aggravates the event.

At first this unpredictability is hard to reconcile with. But maybe it’s not necessary to know exactly how a specific performance in such a system emerges?

Continuing with the “perfect storm” analogy, it might be important to provide individuals with periodic interventions that are delivered under varying “atmospheric” (i.e., psychological or life states) conditions. This means providing repeated opportunities to practice this self-organization under realistic conditions.

Consider “Chinese water torture” – a drop of water continuously hitting the same spot on your head for a long time would not bother you at all, but eventually it would change your behavior completely (driving you mad, so don’t use the analogy literally with your athletes).

“We must do away with all explanation, and description alone must take its place [..] The problems are solved, not by giving new information, but by arranging what we have always known

Ludwig Wittgenstein

Start with what you see. When do athletes struggle in racing or during competition? Describe those situations without explaining why they happen. Separate these situations in the training program and practice them with some variation.

The level of difficulty and overload should not be too high. This might push the system into interpreting the situation as something altogether different from the game-day skill. But not so little that the athlete can complete every repetition with a 100% accuracy (how could a system operating perfectly be pushed into change?).

To practice “what you see the need for” has a few advantages over to base training prescription on hidden underlying qualities

  • By doing so you will measure its success by exactly the outcome which you want to improve. This prevents you from getting lured in a separate direction by confusing some other variable with performance on the field. Every improvement will have a large transfer from training to performance, making small increases in capacity highly valuable.

  • You will move into a territory of training which your athletes are familiar with. This helps communication between the two of you. Communication should not be under-valued. When coaches speak the language of science only, how can athletes be expected to understand the drills they are given? You are more likely to get success telling your athlete to “sprint out of that corner as if you would like to get a gap on your opponent” rather than something along the lines of what percentage of VO2 or speed to hit.

    It will also help you to get relevant discussions on how to tweak the drills. Although athletes might be lacking in scientific knowledge, they tend to know a fair bit about their sports, and these discussions easily extend into how to use the skills you have been working on when discussing tactics.

The downside is of course that you will have to be open with the fact that all you can offer is educated and well-founded guesses. That there is no magic pill. That all the certainty there is to find is that continually doing the things you wish to improve at over time, with some variance and with some overload is what might increase your capacity (mostly by ways of a sudden phase-transition).

If I could have gotten one dollar every time someone asked me for an assistance exercise for a problem – let’s take the execution of the weightlifting movement of the snatch for instance – and seen the disappointment in their eyes when my first choice of exercise was to do exercises not completely different from with is done in that movement. I’d rather pick an exercise to emphasize or correct the point of the lift where I felt the problematic outcome initially did arise.

This places a lot of demand on the coaches communication skills in order to get the buy-in from the athlete. A buy-in which you could have gotten by dangling a mathematical carrot on a stick in front of the athlete. It will also in my experience bring about more compliance and less injuries when you get the athletes involved in the actual process.

I started working with this young and gifted athlete from Portugal a few years back. He had made the transition from Volleyball into CrossFit where he now had some success, qualifying and performing well at the 2018 Regionals. He also struggled with some of the integral movements of the sport, such as the weightlifting movements – most noticeably the snatch.

He was catching most of his Snatches in front of him, forcing him out of balance. Unfortunately we live at quite some distance and cannot do better than to have close contact over the internet. After a lot of questions and answers and sending videos back and forth we agreed that he had trouble already at the starting position, struggling to find initial balance against the floor. This in turn leads to his position being too upright when the bar passes the knee. His joints then are not properly set up to allow him to hit what in weightlifting is often referred to as the Power position

Without going into too much detail, the Power position allows for rapid extension of the knee and hip along with plantar flexion, in a sequence called the proximal-to-distal sequence, where extension on the joints one by one allows at least one joint to have a favorable translation relationship throughout the full extension. The failure to hit this position can force the barbells necessary vertical movement slightly forward, getting the lifter into all kinds of problems catching it.

Over the coming period we did quite a lot of

  • Snatches from power position, with clear instructions on what would constitute a “good rep”, having him to learn and discover on how to generate force from that position. If he could not move from this position without a slight “swinging motion” or if he had to jump forward in the catch he would know that he did not find his Power position properly.
  • Snatch deadlifts, playing with and learning how balance felt. (Balance is tough, as it is really the absence of feeling. Athletes sometimes tend to seek out more distinctive tension, something they feel, as you would find when you are more on your heels or on your toes)
  • From knee to power position and from floor to power position.
  • Full snatches involving the feeling for positions he learned by the above exercises.

Slower, faster… Mixing it up with some fatigue and eventually hitting the positions and moving between them became more second nature for him. 

Not once did we do any movement that was fundamentally different from the movement that he struggled with, hoping to increase some “underlying quality” possibly holding him back. Surely, we still trained those underlying qualities, if they existed, by overloading and stressing the movement that involved them. With the added benefit of a more direct transfer and possibly better understanding and feedback of his process.

We also did not measure the performance of the assistance exercises, more than if they successfully challenged the positions where we thought we saw a lack of efficiency and balance. They were always viewed in the light of the performance of the full snatch.

João has gotten more proficient with this movement: here he is, at the end of a 30 minute workout, hitting a 110kg Snatch, rowing 500m in 1 minute and 40 seconds (something not done without breathing hard), then hitting another 110kg snatch just after coming off the rower something that he could not do in isolation before.

Is this the best way to conduct training? Certainly not always! There will always be cases that are different from all other cases. Every method has its place. 

It is a simple process helping you not to get completely lost in the “data” jungle, or if you are, to find your way back onto the field, where the actual athletes live.

Stay tuned for more examples of practical implementations of these principles in part 2.
