SELF-HANDICAPS!!!

Prof. Juan Martín Miranda

How many times we hear in a crag or in a comp, that wall conditions do not help, that previous night we didn´t sleep well, that the holds are humid, that I do not have enough strength, etc., especially when climbing is stimulated by evaluation pressure, like public approval (not necessarily in a competition, but the pressure of the nearby friend), achieving a new onsight or redpoint level, or a competition, where the uncertainty for the success or failure is an important agent of pressure. These self-handicaps can be real or imaginary.

Self-handicapping are any action or choice that prepare a person to be responsible of failure. In agreement with Jones and Berglas (1978), the self- handicaps are obstacles created by the individuals in anticipation to a performance failure. These behaviors allows to externalize the mistakes and failures and internalize the successes, accepting the credit of the achievements and allowing excuses for the failures. It has a double function, it allows the individual to diminish all that of the personal skill that plays a major role in failure (protecting the selfsteem) and in case of success, it increases the skill of the sportmen, since the success was obtained in spite of the obstacles. (increasing the selfesteem) (Prapavessis y Groove, 1998)

Martin and Brawley (2010) concludded that self-handicap can also be understood from the own efficiency. The sportsmen would use excuses in situations where they have poor efficiency for their skills or to introduce themselves in a certain way (i.e.: I am not good at overhangs, technical moves, etc.).

Those individuals with low selfsteem tends to use more frequently the self-handicapping before a performance that those of high selfsteem, since they encounter more situations where they are uncertain about their ability to solve the task (Prapavessis and Grove, 1998). The athletes who frequently use the excuses incline to take commonly the responsibility of potential failures out of himself and in case of team sports, inside the group (Prapavessis and cols, 2010).

All these excuses that we self-impose, are impediments before a performance. People who use these impediments or self-handicaps can be divided in two categories: chronic or occasional. The chronic selfhandicappers use self-handicaps that are more applicable over time and in varied situations, as physical or psychological symptoms. The occasional ones use self-handicaps for every specific situation.(Ferrand and cols, 2006)

The more frequent self-handicaps used by the sportsmen before a competition are the study and physical conditions or injuries, but they change depending on age, level and sex.

Ferrand and cols. (2006) analyzed the self-handicaps of 6 french elite teenager climbers in three major competitions, where they had the aptitude to reach the podium, with this goal setted by their coach. Before every competition, they had to report their self-handicaps that might affect performance.

The results that the study showed are summarized in the following table. Self-handicaps can be categorized in 6 categories.



It has been argued that the criterion that the trainers use can impact in the way that the climbers perceive the environment, which can be a source of stress in the teenagers elite athletes. The climbers of this study report different types of impediments that allowed them to deflect the reason of the failure away from their sport competente and reduce the coach´s expectations in the subsequent performance.

The repeated use of self-handicaps might place the athletes at-risk of motivacional difficulties that might have a negative effect in the long-term development and performance.

The authors conclude: ¨it is important for the trainers to gain knowledge of self-handicapping, to take into account the rehaznos underlying self-handicapping hmong teenagers for practical implications, and to examine more closely the ego relevante of high level context which may be an important factor determining self-handicapping in a sport context.¨

One important goal for coaches is to understand the reason of the previous impediments and to work on them to impede a performance reduction. Too many exigency, and the exposition of highly sressful goals in young climbers can lead to long-term consequences, like quiting the sport.

From athletics methodology to climbing. Fartlek method.

Prof. Juan Martín Miranda


To write this post I had to dig into some old training books of my student time, specially Prof. Jorge de Hegedus book: " The science of sports training " in which I would find the historical bases of what I want to detail.

" … on the fourth decade of our century (XX) there started being delineated two currents of work that in spite of their differences, had the same common denominator: to adapt exclusively to the means that the nature offers "


foto: A. Uzal

“On this premise there arise two eminences of the sports training (specially the athletics): Gosse Holmer and Gosta Olander.

The first one (Holmer) , founder of the Fartlek method (in Swedish: play with the speed), training method that includes all kinds of speed variations. This method can be summarized:

1- Efforts realized exclusively out of track

2- All kinds of distances combinations during the course

3- Intensity of the distances regarding their length

4- Rest periods related to the distances and characteristics of the run

Hereby a training session according to these slogans might have the following scheme:

a- Easy run to warm up

b- Médium speed run

c- Fast walk

d- High velocity sprints reps

Undoubtedly training hereby is not a very systematic and planned method, since the effort intensity is regulated by the athlete subjective sensations .

On the other hand another Swedish trainer, Gosta Olander, continuing with this current of training in the natural way, was taking advantage of the difficulties imposed by the area in which the sportsmen realized the training, since it can be mud, now, different inclinations, etc, that it were offered in his prestigious training center of Vololaden, in a former hotel lost in the depths of Sweden (for the fanatics of the athletics I recommend the website: www.vololaden.com). Giving more importance to the intensity of the actions than the tempo of the same ones.

Prof. Yuri Verkhoshansky proposes aerobic Fartlek method to increase the anaerobic threshold. It consists in a uniform and prolonged run with 8 to 10 (or more) seconds sprints every 10 to 12 minutes.

Well then, we have seen that this type of training takes as a premise to go adapting to the terrain in which it was realized, and therefore the intensities are imposed by the terrain. And is not this is what happens in climbing??

It is almost impossible to find climbing routes of that are completely uniform in their intensity, since they can have different angles, one o more crux, good, bad rests, without hands, technical moves, hard moves in roofs, everything what we can imagine. Whenever we climb a different route, we will face a completely different ground, which will force us to alternate different effort intensities, as is it is done by the Fartlek training method.

In an article published in Engineering of Sport (2006), M. Michailov experimented with this method on climbers with the idea of improving their anaerobic threshold. Six climbers were trained for seven weeks, three times for week with a specific training plan that alternate intensities during the climbing bouts

2-3 sets of 8-10 reps of: 20-30 moves easy route and 15-20 moves hard routewith 30-60 seconds rests. Sets rest was 20 to 30 minutes.

The aim was to climb near the anaerobic threshold heart rate estimated by ergometry. The author mentions (and it is a part of the conclusions) that heart rate is not an indicator of climbing intensity, but it was used to control that the climber is near to the threshold heart rate determined before, same conclusion at which Burnik and Jereb (2007) arrived after evaluating 11 climbers in three different intensity routes.


He used two different test to evaluate the improvements, the first one consisted on climbing the major quantity of movements during 5 minutes in a 120 degrees overhang wall to determine the capacity of mixed energy (anaerobic aerobics) supply and the second test performed in a roof wall during 1 minute, to determine the anaerobic lactic energy supply. The results showed an improvement of 32 % and 43 % in both test respectively.

Beyond the difficulties of evaluating these capacities (and obviously the proposed test can be questionable) the improvements are interesting, and definitively this methodology improves the specific climbing endurance.

With this type of trainings in which we alternate different intensities in the same repetition it has some benefits:

- Major specificity of the training

- The special endurance is improved

- The capacity to take advantage of the easiest climbing sections as recovery of the intense efforts is improved

- The in-climbing recovery capacity is improved

Here some Fartlek training drills used in climbing

Traverse + route

For this exercise a route must have from 15 to 20 high intensity moves designed in the bouldering wall where simultaneously we could realize a very low intensity traverse for a long period of time (more than 30 minutes). We must be kept traversing for a period from 4 to 5 minutes and then the 15 moves hard route. Once the route is finished continue with the traverse for 4 to 5 more minutes and then the route again. Keep this training for more than 30 minutes (up to 1 hour).

Broken routes

Design two or three circuits of 15 to 20 movements which the final hold of the first circuit coincides with the initial hold of the second one and so on. The circuits must be linked without stooping, but forcing the recovery period at the end of each one. It is possible to measure resting time, and force it up or down. I.e. a maximum rest time (of 1 minute), or a minimum rest time (of 2 minutes)

Continuous Interbloque:

Design a set of three to six relatively easy boulder problems that starts from good holds. The problems must be performed linked by an easy traverse from the last hold of the previous problem to the firsts holds of the next problem (generally down traversing), and rest in that holds all the necessary time.

Training for bouldering competitions

Prof. Juan Martín Miranda


There are several scientific studies concerning physiologic characteristics of sport climbing, but almost exclusively on sport climbing routes. Recently there were published some articles that describe and analyze bouldering competition demands.


A bouldering competition consist on a series of problems during each stage (4 to 5) with a determined performance time for each problem (4 to 6 minutes), and a similar period of rest/recovery between them. The competitor during his realization time must administer their attempts and rest intervals to solve all the comp that lasts more than 50 minutes.


One of the scientific articles, published by White & Olsen (2010), analyzed the performance of several elite english bouldering climbers during a national competition. Next chart shows the data obtained.



These numbers give us some guidelines about the effort during this type of competitions. Climbers tried only 3 times each problem (mean), where they spent 30 s to solve each. The work/rest ratio (for 6 minutes period) was 1:4 in each problem. If we consider contact time and time to reach next hold (8 s / 0.6 s) the ratio is 13:1. During route climbing this ratio was 3 s : 1 s (Watts et. al., 2000).

Another interesting thing of this study is that static time is lower than route climbing (25% vs 38 %) founded by Billat et als (1995).

Another study by La Torre et al. (2009) analyzed elite Italian bouldering climbing during two national comps and on simulated comp. In the firsts two comps they analyzed working time and lactate concentration at the end, and in the simulated comp they analyzed times, lactate concentrations at the end of each problem and heart rate during all the competition.


The data presented here differs little from the other study (keep in mind that there is a climbing time of 5 minutes here). Mean of each movement time was lower: 5.3 ± 0.7 s for the national comp and 5.2± 0.6 s for the simulated comp. Mean climbing total time for each problem was 65 ± 20 s and 92 ± 24 s and mean total climbing time for all the comp was 391 ± 85 s and 551 ± 96 s respectively.

Mean heart rate during recovery period did not increase in the simulated comp in males, but slightly increased in females.

Lactate concentrations during simulation didn’t raise with the increase of competition time, but mainly depended on the time needed to climb the attempts of the previous problem. Using regression analysis they determined that changes in lactate concentrations depended on effort duration, with an apparent cut-off value of 20 s. Describing this way short attempts (<20>

In the third study (Michailov et al., 2009), anthropometric characteristics and strength of elite bouldering climbers that participated in a world bouldering cup were measured. Next chart shows their results


Elite bouldering athletes had very low body fat and muscle mass close to 50% in males and 40% in females , same as difficult (routes) climbers.

Male climbers had 20% more grip strength tan route climbers (Watts et al., 2000), this is due to the strength nature of the contest.

Conclusions

The intermittent character of the prove, shows some specific determinants in recovery time during each problem, and during all the event. During a competition (more than 50 minutes) some recovery times are stipulated by rules, and other depends on the climbers tactics and strategies and their recovery capacity. The higher the level of the climber and the more experience has, without doubts the climber will give less attempts, administer better the effort, and therefore his recovery times will be higher.

Using specific training means to increase recovery capacity is a must. Intermittent training (aka interbloque) is an excellent choice to increase it. And due to some problems duration (more than 20 s), lactate accumulation must be removed rapidly, so high intensity interval training can be used to increase lactate removal capacity.

With regard to the action time of the muscles (holds contact time), training should be specific to maintain very high intensity intermittent efforts of 5 to 8 seconds approximately with an excessively short rest (<1>

Strength levels for this type of efforts are very high (20 % plus than route climbing), therefore the strength capacity is also another training goal. The climbers must use specific exercises like hangboard training, system training, campus training and especially boulder climbing, which is the specific exercise.

A high percentage of mass muscular derived from the unspecific strength training can be counter-productive, since the climber will have to move his overweight. That’s why any increase of the muscular mass must be specific and necessary to the demands of the event. It is necessary to control it by periodic anthropometric tests. Therefore the muscular mass should be ideal and the hypertrophy should happen only in the determinant musculature of the performance.

SPEED CLIMBING TRAINING PART 3



This is the last post of the speed climbing series. I will show some methodology and exercises.

The speed in a climbing route will depend on two factors: length and frequency of individual moves.

Length depends on:

1- Morphologic characteristics

2 Strength

3- Holds

4- Flexibility

Frequency depends on:

1- Contact time

2- Flight time (COG in vertical direction)

Improving each of these aspects will improve in final climbing speed. Some aspects can’t be changed like anthropometric characteristics or where the holds are screwed. But strength, flexibility, contact time and flight time can be trained and there is where our efforts will be centered.

Methodological tasks

  • - Increase speed possibilities by high frequency innervations using low resistance and a short period of time
  • Increase special strength preparedness using dynamic moves
  • Increase speed endurance using interval method
  • Reach perfect coordination and maximum efficiency of the neuromuscular effort

The following videos shows some methodologies to work upper body strength







Frequency campus exercises




And for movement length





Assisted exercise will be helpful to frequency improvement when using campus board because sometimes (always!!) body weight is excessive to apply a correct speed training load. Using elastic bands attached to a harness will be enough.

Non assisted exercises need to be performed after assisted ones, so we can finish with the real motor path

Methodology

  1. Normal – resisted – normal
  2. Normal – resisted – normal – resisted – normal
  3. Normal – assisted – normal
  4. Normal – assisted – normal – assisted – normal
  5. Normal – resisted – normal – assisted – normal
  6. Normal – resisted – assisted – normal

7. assisted – resisted – assisted - normal

Some exercises to train lower body strength




For power nothing better than jumps




This chart resumes the tasks to train for speed climbing



<


Some reflections concerning speed training

  1. Technique and coordination are important do speed
  2. Max strength and power have a positive effect; max strength, power and speed makes a dynamic unity
  3. Muscular imbalances are counter-productive during speed development
  4. Exercises performed at sub maximal speed generate sub maximal speed neural paths.
  5. It is preferable quality than quantity. Maximum speed improvements is only possible by a complex and well developed process of load planning and control

SPEED CLIMBING TRAINING PART 2

In this post I will show how are upper and lower body moves during a speed climbing comp, and the way this information help us to understand speed climbing training methods.

Upper body moves

Pay attention to this video, specially arms moves



Now let’s see the same video in slow motion and with contact time analysis.



If we analize in numbers what the video shows:

Numbers of contacts 10 left / 9 right

Total contact time 4,08s/3,6s

Double moves 4

Average contact time : 360ms

Esplosive actions with stretch shortening cycle (SSC)

There is few cientific studies published concerning speed climbing. Konstantin Fuss and Gunther Niegl (2006) studied climbers forces during different situations, using piezoelectric sensors attached to holds to determine how forces is applied on them.

They concluded that during speed climbing as higher the reaction force over the hold, higher initial shock spikes , and shorter the contact time. So it is necessary to apply high forces in a short period of time, thus reduce the contact time. Keep in mind that if we reduce each of the contact times , we will have a less time until the top.

A




t this point, a striking difference becomes apparent: in lead climbers, the better a climber is, the smaller are the contact forces at the hold: in speed climbers, the opposite is true, i.e., the better the climber and thus the faster, the higher are the contact forces. In lead climbers, the magnitude of these forces depends on how economical the climbing style is; in speed climbers, the force is a function of speed (Fuss and Niegl. 20O6).

Next graphs shows forces and contact time / velocity



Number of moves shows that during comp format (15 meters tall) and with accurate technique, a climber do 19 moves, 4 of them are double dyno.

Average contact time is between 300-500ms, classifying some of the actions as Long Stretch Shortening Cycle actions (SSC-L), that means that there is some elastic energy stored and released during the contraction. This determines some parameters to consider when planing the training to maximize the efficacy of each move

Lower body moves

Next Image shows lower body moves.





Number of contacts 9/9

Both feet at the same time: 1

Average contact time : 400ms

Explosive isometric-concentric actions

Knee: >90 grados

Foot internal rotation, Hip abduction

Number of contacts is similar to upper body, but contact time is higher, maybe because great angular amplitude of the involved joints.

If we see the knee in each move, we will notice that they’re flexed more than 90 degrees at the beginning of the move. So they’re deep knee flexions.

At the same time each move is performed with feet external rotation and hip abduction, that determines an specific pattern to train lower body.

All this actions are considered explosive isometric-concentric actions, because the climber first fixes his feet, and then perform the explosive concentric action always with upper body support.

Next post I will describe methodologies to improve efficiency of upper and lower body contacts.Prof. Juan Marín Miranda

Speed climbing training


In this series of posts I will analyze a purely competitive climbing discipline: speed.

This discipline is growing in the competitive world, and is one of that is in the sight to be the representative in the Olympic Games.

According to speed climbing rules two formats are possible, record format and classic format. In the latter the athlete climbs two routes in each of the series of the same height and similar profile and difficulty, whereas in the record format (15 or 10 meters standard wall with standardized holds located in a precise position) the climber climbs once in each of the series. This videos are an example of both formats.

Record format




Classic Format



The speed implies the velocity with which a body does a displacement in the space. So the speed is the resultant the space crossed by the time used.

From a sports point of view the speed represents the capacity of a subject to realize motor actions in a minimum of time and with the maximum of efficiency. Therefore to demonstrate speed we must known which are the determining factors. The speed is a hybrid quality that is determined by all other qualities: strength, endurance, and especially by technique.

Speed must be learned and trained always by specific exercises, and these exercises must be realized at high speed, so by this way we will assure ourselves fast movement paths.

Speed training has two manifestations:

QUICKNESS: all the isolated actions that are constituted by one movement. 

SPEED: linking movements in a given sport action

This way we see that we can improve the quickness of each move, and then link them. If we use the record format, where all is standardized, the training would consist of maximizing the quickness of the individual movements of then link with speed.



The training objectives are:

· Treduce reaction time

· Maximize the acceleration of the displacements

· Increase the speed of each move

· Achieve major moves frequency

· Reduce the contact time on each hold

· Reduce the speed loss

Reaction time:

It is the time between the beginning of a stimulus and the beginning of the response. This stimulus in case of the speed climbing is a simple stimulus: the judge order.

Consist of 5 phases:

· t1: the interval of time that elapses while the climber detects the sensory input from the starting order

· t2: the length of time needed to acknowledge and correlate the array of sensations discovered in t1

· t3: the total time required to organize a response

· t4: time required to the stimulus to arrive to the muscle motor plate

· t5: time required to initiate and complete a specific movement

This area is one of the most difficult to train and obtain improvements since we are speaking of miliseconds. In the following table, I present the reaction times (RT) of the 100 meters flat races 5 best times.





It is well-known that less than 150 milliseconds it is the time of reaction to execute the first movement. If one delays it or gives an advantage from a slow start it can be the difference in the classification. There is not enough information on speed climbing reaction time, but this training area can offer to us valuable milliseconds in a speed competition.

The methodology to train the reaction time has some requirements

· Start from simple conditions of execution.

· Go on to changeable conditions.

· Low volume of work and exercises

· Exercise them in the first part of the training session

· Improve visual and propioceptive feedback mechanisms

We will always try to begin the reaction time training without previous fatigue, and with simple execution drills.

The idea is always to vary the stimuli to which the climber must react. The stimuli can be tactile, auditory, visual.

But looking for specificity, at the end of the reaction time session we will focus on specific starts, doing only the first one or two moves.

The work volume must be low, since it can generate sensorial or physical a fatigue that it will prevent to react quickly generating slow motor pattern.

Normally with 15 or 20 minutes of reaction time at the beginning of the training session we will have a suitable stimulus.

The following post will be dedicated to analyze the moves of the upper and lower body in the format record, and later we will see the training methods to improve the quickness and the speed..
