TRAINING FOR CLIMBING. IS REALLY NECCESARY?

Climbing is a multipurpouse activity, competition, hobby, way of life, etc., each climber might have their motivations, but one thing is clear, each one wants to climb more: harder routes, more routes in a day/trip, climb faster…

Even if we don’t link climbing with high performance sport, those targets denotes a similarity with sports activities where ones always want to perform better and exceed previous level and it is not necessary to compete with others!.

There are several ways to improve in our climbing: climbing itself in an anarchical way, just climb anything in an unplanned way each climbing session, or plan and organize our climbing sessions, following the advice that give us the theory of sport training.

By this way we can perform and success in our objectives in a precise time. Training is defined as a process, with a starting and an ending point. The starting point is the initial state at the beginning of a training plan, the ending point is where we are going to achieve the results, a trip, a comp, etc..

The initial state is the sports form where we are, analyzing the preceding performances in climbing and the training backgrounds that we have.

Objectives are the fundamental pillar of each training process, because they determine the ending point and with that the motivation to realize the training program during the different stages. Objectives must be defined previously in a clearly and concise manner. Some characteristics of the objectives are shown below:

Clearly formulated

Realistic and accessible

Measurable

Specific

Once objectives are defined, we have to see how will be completed trough a training plan. Basically we the training we want:

Increase the organism motor potential

Improve the ability to use effectively this motor potential

Increase the sports mastery firmness

Training is based on the administration of different loads to the organism that will produce an effect named supercompensation, in which the organism once stimulated, and during the recovery period, it is regenerated up to overcoming the initial state as measure of adjustment. All that happens if the period of rest among training stimuli is correct. If the period of rest is incomplete, the organism can’t adapt to training, and the state will be low. (FIGURE 1).



There are several possibilities to administer the training loads, looking for the ideal lapse of time to reach the maximum benefits, keeping in mind that these loads always must be of major magnitude as one progresses. (FIGURE 2)


But this supercompensation curve cannot demonstrate eternally in an ascending way. It is necessary to offer to the body every certain period of time a major rest, in order to avoid overtraining.

There are several ways to administer the loads: (FIGURE 3)


Standard: when always do the same thing independently of the session, in which we will come to a stagnation. For example, if every day at the end of the training sessions we do 10 laps on the same route to increase our endurance, we will stop in the progress rapidly, for it we will have to choose to change the organization of the training loads.

Progressive increase of the loads: consists of a constant increase of the training during the sessions. But we will come to a point where the organism will not be able to adapt any more to this constant increase of the load, and will come to a point of stagnation, and more even to a decrease of the performance due to overtraining. An example of this, instead of doing always the same 10 laps of the same route, increase session to session the number of routes (11, 12, 13, 14) or increase the difficulty of the laps.

Stepwise increase of loads: this methodology consists of doing periods of 2, 3 or 4 weeks of increase of the load for 1 or 2 weeks of decrease of the load or recovery to allow the supercompensation. On the same example of the endurance training at the end of the session, one might realize 10 laps the first week, 12 laps the second, 14 laps the third, but in the fourth we will lower the load to 10 laps. This way we will have a stepwise progression. The following period of training might begin again with 10 laps, but a more difficult route.

This recovery period is applied also before the performance period. It is called tapering, and is a period before the trip of climbing, competition, etc., in which we will give a rest to the body, especially across a decrease of the volume of what we are doing, in order to arrive to the supercompensation and perform with success.

This methodology is the modern strategy of training and is in use definitively in the training of the climbers of average and high level, since trained climbers organisms needs progressive and well planned loads, with periods of intermediate rests.

This division in weeks of increase of the load with weeks of decrease delimits specific periods of training, in which it is possible to emphasize in some aspect of the specific conditioning for climbing.

For example, and depending specifically on the goals, in this case 4 months (16 - 18 weeks) from the beginning of the training, one might organize three periods of training or mesocycles:

1er mesocycle: adaptation to the training loads where the first 4 weeks (three in ascent and one in decrease) will be dedicated to the increase of the work volume, a lot of time climbing on easy terrain, or to do routes of moderate/low difficulty, but many times. The aim here will be to create the basic conditions to support the training loads and to adapt all the body structures (muscles and tendons).

2nd mesocycle: improvement of the maximum strength and power, also a 4 weeks cycle, with three weeks of load increase and one of decrease. The general goal will be to improve the forearm muscles strength and all the back muscles. Here we will seek to have the aptitude to solve the isolated movements of the project.

3er mesocycle: period dedicated to the special endurance improvement, with this we will be seeking to acquire the aptitude to resist the quantity of movements that needs the type of climbing that we want to perform. During 3 weeks in ascent, then we will rest into the following period (tapering). Here we will centre on looking for the necessary endurance for the route/s. If our goal is 20 moves routes, we will focus on acquire this specific endurance, the same for 40 moves routes, or more, or if we are seeking to climb many routes in one day, we will focus a bit more on the work volume. We will achieve this last goal by doing sets and reps of routes of the desired length.

4to mesocycle: Adjustment or tapering, for 2 or 3 weeks, we will try to regenerate the organism to arrive to the performance period in the bests possible conditions, and all the adaptations arrives to their maximum level of efficiency. Here we will diminish the volume of work, with big rests and especially arrive progressively to maximum intensity (difficulty).

With this simple periodization it will be possible to coincide maximum point of performance with the date foreseen for the next trip of climbing or CHAIN. This is not a rigid structure, but will change depending on the goals, time to train, sport form, etc.

CONTACT STRENGTH (PART 2)

In the previous article I demonstrated the importance of contact strength with the rise of climbing level. Due to the intensity of this kind of training it is not recommended to novice climbers

To increase this capacity we could use climbing itself or use the campus board as a fundamental tool.

Contact strength training via climbing

As we saw, contact strength is the capacity to apply the higher strength as possible in the minimum amount of time, so, using climbing as a mean to increase contact force there are some activities:

Speed climbing: climb as faster as possible, toproping or bouldering. It’s a funny exercise. Main idea is to think holds are super hot, so you have to leave them as soon as possible. Sets must be 8 to 10 sec max to develop powerful movements, and rests must be complete (3 minutes)

No foot climbing: no foot bouldering is ideal to increase your contact strength. Once your increase your ability you could reduce holds size. Always in a maximum of 6 movement problems and a complete rest (3 minutes)

Contact strength via campus board

Campus board is a training mean that has two different goals: to train finger flexors contact strength and to train back and arms strength and power. Wolfgang Gullich started using it in 90´s, and then this tool became popular among climbers.



Campus board is an excellent tool to increase contact strength. But several cautions must be taken. Definitely isn’t a tool for novice climbers, and it is not recommended for climbers younger than 17 years old that haven’t arrived to full bone maturity, because finger joint trauma generated by campus board can generate fractures, as been well documented in Audry Morrison and Volker Schoeffl studies (Physiological responses in young rock climbers).

There are two groups of campus exercises:

Reaches and pushes: consists in climb rung to rung with one hand while the other stays in the first rung. Main goal is to reach the highest rung as possible either by the pushing with the lower arm or pulling with the ascending arm, or both in a coordinated manner (better). This exercise and some variations (watch this video) don’t generate excessive impact in joints, because always body weight is supported by the lower hand which adds more control to the movement.



Even so, exercises can be classified by their impact. High impact exercises are exclusively for high level climbers, and low impact exercises are for medium level climbers.


Simple reaches: ascending rung to rung

Double or triple reaches: ascending skipping one or two rungs

Maximum reaches: ascending up to maximum extension as possible, here you have to pay attention to full extend lower arm.

Jumps or dynos: they consists on jumps with both hands at a time. These jumps can be ascending or descending (catching a lower rung).



As with pushes and reaches, an impact classification can be done with jumps



Simple dyno: jump from rung to rung (big rung) with both hands

Plyometric combinations: using simple dyno basis, jumping up and down , or jumping up skipping one rung and jump down one, and all simple combinations of simple dynos, but always respecting movement velocity and descending only one rung and ascending skipping one rung max.

Between 6 to 10 jumps for both exercises, or once movement velocity is lost. $ to 10 sets with full rest (3 minutes)

Doubles, triples, maximum dynos: skipping one, two, three, etc rungs, reaching the highest rung as possible. 4 to 6 jumps, 4 to 10 sets and full rest (3 minutes)

All of these exercises could be more intense by reducing rung size, but this strategy is only possible when all the variations are dominated and climber level is high.

Recomendations:

  • Analyze if you really need to add volume to your training..
  • Determine if you have enough capacity to tolerate a high intensity training.
  • High strength levels are necessary, and without actual or recently injuries in fingers or elbows joints, muscles or tendons.
  • It is not recommended to add any of the high impact exercises to low or intermediate level climber’s workout.
  • Campus board is a tool to develop strength and power, so sets must be of low volume (4 to 6 reps) and rests between sets must be complete (3 minutes)
Each campus training session must start without previous fatigue. If this happens, it would be very difficult to maintain enough power , and the lack of coordination could be an injury factor due to the intensity of the exercise.

CONTACT STRENGTH (PART 1)

Each time we grasp a hold, we have to do enough strength to support our body weight. But what is contact strength?

Contact strength forces are the forces that occur between objects, and they can be resolved in two components: the force that acts perpendicular to the contact objects (hand – hold) surfaces and the component that acts parallel to that surfaces (friction). (McGinnis 1999)

Climbers main motor force is the first component, and friction allows the climber to exert that motor force.

Friction between two bodies doesn’t depend on the size of the contact surfaces (hand – hold), but depends on the nature of both surfaces.

Magnitude of friction forces is proportional to the Normal between both bodies; that means more force we apply, more friction we generate. When friction acts between two surfaces that are not moving, it is referred to as static friction, and when your hand is sliding from the hold is referred to as dynamic friction. Each time we grasp a hold we want a static friction, so we have to apply a higher force than dynamic friction.


Well, now we know that we have to apply enough force (strength) to catch a hold, and if we analyze a little more, to get more friction force we’ve to apply even more strength.

As sport performance increase, conditions to apply force worsen: the climber will have less time to apply strength, since the same action will be done with greater velocity. So time to apply force is reduced with the increase in sport mastery, and the only solution to this is to improve the force-time curve, that means apply more strength in less time (Badillo y Serna 2002).

As the climber’s level increases, routes are steeper, and hold needs more friction force. But we have to apply the greater force as possible in a short period of time, since if we don’t apply enough force in the precise instant we contact the hold, the force generated by our body weight (gravity) will be enough to impede grasp the hold.


In the force time graphic, we will see that an athlete can apply his maximum strength (100%) in 0,4 sec, An excessive time if we calculate the necessary time to grasp a hold that needs a lot of friction; on the other hand, in less than 0,2 sec the athlete can apply 50% of his maximum strength. That means that the useful strength of this athlete is 50% of his maximum strength, thinking on apply strength as fast as possible.


In the left graphic, we can se how two athletes with different maximum strength con grasp the same hold if the required force is 400 Newton in 200 ms. On the other hand, in the right graphic two athletes with same maximum strength, but in 200ms the continuous line athlete can exert higher strength, so he might have better possibilities grasp holds that requires higher strength levels in lesser time.





This video (extract from Fanatic Search) shows how contact strength fails.

That’s why finger maximum strength and power (strength/time) or climbing specific contact strength has to be one of the main goals of a climbing specific training program.

Next article I’ll show some ways to train contact strength, using climbing, fingerboard and campus board.

Nutritional aspects to optimize climbing training and performance

One of the climbing performance key factors is the body weight. Climbing depends in it. We shouldn’t forget that move extra weight will add an extra load to the muscles that are involved in climbing, mainly in overhanging walls, where it’s more difficult to use your feet to support weight and this way help upper body.
Maintaining body weight in optimal values and reducing weight to minimum is a must for performance.
In the graphic you will see the different body sizes of an elite climber in relation to the population media (Phantom strategy). Skin folds are between 2 and 3 standard deviations, which means a very lean body.
Legs perimeters are below the media, but upper body perimeters (forearms and arms) are above.Body weight is a sum of 5 different tissues: muscle, adipose, bone, organs and body liquids.
One of the ways to measure those components is doing an anthropometry, which determines the percentages of each component and with that information one can decide if it is necessary to modify body composition to optimize performance.
The next graphics shows the different component percentages of an elite climber and it comparison with the media (Phantom)

Note again, that the adipose mass is between 2 and 3 SD below the media, and the muscular mass above.

Muscular and adipose mass are the values that can be modified by training and nutrition. Upper body muscular mass (muscles) is one of the fundamental components of climbing performance, and for that reason is a must to maintain it or sometimes increase its volume. Sometimes is recommended to reduce lower body muscular mass by a specific training (low intensity aerobic exercise)
But body fat is useless in climbing, and is a must to reduce it to the lowest possible values.

It’s interesting to note that some levels of body fat are necessary to maintain body normal functions, so some minimum levels are required: 15% for men and 20 % for women predicted by Kerr 1988 anthropometric formula.

Nutrition is one of the factors for reduce or maintain body weight, determined by the caloric intake.
To reduce body weight it is necessary to acquire a negative energetic balance, which means that the energetic intake must be lower than the energy consumption.
There are two ways to do this: reducing caloric intake or increase energy consumption (by training).
Some recommendations to reduce weight:
- Moderate caloric restriction (-500 to 1000 Kcal/day)
- Low fat diet (20-35% of the total caloric intake)
- Moderate protein diet (15 to 25%)
- Carbohydrates 55-60% of the total caloric intake, using simple carbs are preferably
- Include foods rich in fibers like fruits and vegetables

Excessive food intake restriction might be dangerous for performance. It is necessary to maintain energy levels to support training loads, and recover from them.
Nutritional strategies to reduce body weight will be a guide for all day diet, but it is very important to start training with full energy stores, and during the recovery period assure the essential components to accelerate and complete it.
It’s necessary to adopt specific nutritional strategies for each climbing training session.

Previous to each climbing training session you must eat enough carbohydrates to maintain the activity throughout the whole period of time. If it lasts more than one hour it will be necessary also to ingest carbohydrates during the same training session.
In turn to recover it is important to consume them after training, before two hours of having concluded. Carbohydrate sport drinks are a good option if you don't tolerate foods in the stomach during training or immediately after finish.
Consider that not only the quantity or type of nutritious is important, but also the time where they should be eaten, if you eat them during the two previous and/or later hours to the workout, the benefits are amplified.
If the goal of the training session is the strength improvement, you’ve to supplement the carbohydrates intake with proteins, especially branched chain amino acids (BCAA) to avoid the muscular catabolism (muscular fibers rupture), characteristic of this type of trainings.
The BCAA constitute near 33% of the total of amino acids that form the muscular proteins, and they are fundamental to stimulate and regulate the protein synthesis processes
There is enough scientific evidences that indicates that the BCAA supplementation is effective to improve recovery speed and to stimulate the protein synthesis. On the other hand, they have also benefits to attenuate the mental fatigue provoked by a serotonin excess (cerebral neurotransmitter that regulates the neural activity) that could induce to apathy and performance reduction.

A wrong way life

The title of this post is from my best friend Nari that defines all their desires some time ago, where he was so passionate about climbing, but 400 km away from any rock. It is very probable that if he had been born in the best climbing place in the world he had wanted to dedicate to surf with the sea so, so far...

But now he lives climbing somewhere in Europe.

But take it easy Nari, you still on the wrong way.


What I mean is that no matter how much we are devoted to training, getting adaptations in muscles, more endurance, more strength, more power, improving our technique, tactics, strategy, or whatever comes to mind, it is very probable that we cannot transform our organism to such a point that climbing can be natural. Everything unless we win in some way to THE EVOLUTION

It will be very difficult to win the fight against thousands of years of evolution, not in vain we stop to climb to adapt to a walking life getting all the comforts of the modernity.

One of the main differences that separate us from the monkeys is the thumb opposition, which allows to hold things with more precision, but when we’re eock climbing we don't know what to do with that thumb that we uses so much pinching all plastic holds, unless we find a big pinch on the rock.

But the idea here is not to outline problems, just to try to solve them.

Our predecessors lived in trees approximately about nine million years ago, as today lives the chimpanzees. Later a separation took place in the line of the evolution: on one hand the big monkeys, and in the other hand, the men. It probably begins here the development of the hominids, and the man's history, of Homo sapiens, and of their predecessors, Australopithecus, Homo habilis, Homo erectus and Neandertalis. All of them are extinguished. We are still the only hominids alive. Different monkeys have also survived: chimpanzees, gorillas, etc.

It is important to notice that the biological evolution makes reference to the populations and not to the individuals; also the changes should pass to the following generation. In the practice this means: The Evolution is a process that appears as a result of the heritable changes in an extensive population through many generations.

We can’t deny that with training we produce changes and adaptations in our own organism (THE TRAINING LOAD IN SPORT CLIMBING article in www.marvinclimbing.com). Those adaptations are those that will allow us to improve and progress.

But as individuals we will never end up possessing the characteristics of the monkeys, no matter how much we effort.

We have to think in the evolution!!!

The secret here is to achieve the best adaptations in our organism through practices and training and to PROCREATE to be able to transmit those adaptations to other generations.

For that reason I go for my second son

adding extra weight to the climbing training session

Sometimes training stimulus in climbing should be more intense than the normal, especially in high level athletes with a huge training record (several years, several hours per day).

The training intensity can be increased by increasing the wall angle and/or diminishing the holds size. But if the wall angle overcomes 50-60 degrades the technique gets complicated (it’s more like a roof), and when diminishing excessively the holds size it can be dangerous for the hand joints and tendons and inclusive a bit painful.

To get adaptations, the intensity of each stimulus should be bigger than the previous ones; and when the possibilities of the two previous variables are drained it is necessary to use another strategy.

At this point you can add extra weight to our body to increase intensity.

That has many purposes:

- To increase the intensity of the training of the flexors of the hand, and all the involved muscles

- To diminish the time of total training

- To generate more intense stimulus to provoke adaptations when plateaus take place

- Well planned gets extraordinary results in high level athletes, but in intermediate and low level climbers, it can interfere in the attainment of effective technical expressions and mainly provoke injuries when adding too much stress in the joints, muscles and tendons.

The weight that should be added should not be in any moment superior to 5% of the body weight. The best way to make it is through a weighted belt, so that the added weight is located near the body center of gravity. The vests ankle belts are dissuaded, the first to interfere in the movements of the shoulder, and the seconds because they generate an excessive load in the knee when making foot movement, and both methods change too much the body center of gravity.

Each time you finish your weighted workout you must do several climbing movements without the extra weight, means the last set of your session or at least a couple of boulder problems. This way you can rearrange the corporal scheme to the normal position of the center of gravity.

Some recommendations:

- This method is exclusive for climbers with a wide record of training

- It should be used in climbers with great consolidated movement repertoire

- Immediately after a weighted session it’s advisable to transfer the training to an unweighted climbing

- This method is great to increase strength, and also it can be used to add intensity in the different types of endurance training.

- This method should be located in specific periods of training (concentrated loads or shock microcycles)

- The recovery time among sessions should not be smaller than 48 hours, due to the excessive load provoked in the joints, muscles and tendons.

- The use of regenerative measures is recommended to increase the recovery in the weighted climbing periods.

BAD LUCK FOR THE CAMPUS

Contrarily to what many training for climbing gurus think, campus training would not have the capacity to be a plyometric.


In a recent study of Francoise-Regis M. Thevenet (Master in Investigation Thesis, France), he analyze the inter-joints coordination, angles, angular speeds and times of force development of three sport expressions: a Squat Jump (jumping from squat position), a campus jump with both arms and a dyno (common movement in climbing where arms and legs are used in a coordinated way).
Inside the conclusions of this study we can see that the times of force development until the arms take off in the campus jump are 691 + - 10,5 ms; keeping in mind that after 450 ms the nervous system can regulate the movement by the intervention of the antagonistic muscles, and the myotatic reflex, impeding the development of the increased power involved in plyometric activities. Due to that duration of the force expression, the campus jump cannot be considered a dynamic expression as a jump.
Comparing the campus jump with the squat jump and the climbing dyno, the movement speed and the reached height is lower (0,11 mts against 0,27 mts and 0,48 mts respectively). The problem resides in that the upper muscles should displace 90% of the corporal mass, with much smaller muscular volume that when the legs are used in the jump, or the legs and the arms in the dyno.
Also the take off in the campus jumps takes place when the joints almost arrives to its most favorable angle to produce force (90°) where the back muscles (latissimus dorsi) will be the main motors and arriving almost to the maximum flexion (52°).

On the other hand during the dyno, the coordination between legs and arms outlines an use of different musculature. The legs are the main motors, while the arms maintain the body near the wall, completing a hinge function.
Plyometrics implies an eccentric (stretching) contraction immediately followed by a concentric contraction, in other words stretch the muscle before contracting so that the accumulated energy during the eccentric contraction is released during the concentric contraction producing a more powerful movement. But the main characteristic is the duration of the impulse phase (concentric contraction). This is denominated Stretch Shortening Cycle.
Actions that overcome 350 ms lose that whole accumulated energy, so they are not plyometric exercises.
By the way not everything is lost in campus training. It is an indispensable tool for training for climbing in high level athletes. If we use both arms from complete extension as it outlines the previous study without a doubt the times of force development will be excessive, but if we limit joint range, the action have the capacity to be plyometric. At the moment I am developing a device to measure the hands contact time in the campus in repetitive campus jumps, that which will be able to clarify a little more on this topic.
As always there is a lot to investigate, but campus has many utilities, not only arm jumps. To know more about the training with campus you can check www.marvinclimbing.com
