Triathlon in the Postmodern Era

Long time ago we began speaking of the Postmodern Era, it is impossible to give a date when it started, but the transition from Modern Era is slowed and we have seen it mature over the years.  I even gave a Grand Rounds Conference at SUNY Syracuse (1993) titled: “Medicine in the Postmodern Era.” I like what Umberto Eco wrote about it in “Apostille au nom de la rose.”
“I think of the postmodern attitude as that of a man who loves a very cultivated woman and knows that he cannot say to her "I love you madly", because he knows that she knows (and that she knows he knows) that these words have already been written by Barbara Cartland. Still there is a solution. He can say "As Barbara Cartland would put it, I love you madly". At this point, having avoided false innocence, having said clearly it is no longer possible to talk innocently, he will nevertheless say what he wanted to say to the woman: that he loves her in an age of lost innocence.”
“Thus I rediscovered what writers have always known (and have told us again and again): books always speak of other books, and every story tells a story that has already been told.” ...

“The fine thing about pacts with the devil is that when you sign them you are well aware of their conditions. Otherwise, why would you be recompensed with hell?”

The Jewish said: 
What has been will be again,
what has been done will be done again;
there is nothing new under the sun.

Trump is the metaphor of Nero:
History has blamed Nero for the disaster, implying that he started the fire so that he could bypass the senate and rebuild Rome to his liking. Much of what is known about the great fire of Rome comes from the aristocrat and historian Tacitus, who claimed that Nero watched Rome burn while merrily playing his fiddle. Gangs of thugs prevented citizens from fighting the fire with threats of torture, Tacitus wrote. There is some support for the theory that Nero leveled the city on purpose: the Domus Aurea, Nero’s majestic series of villas and pavilions set upon a landscaped park and a man-made lake, was built in the wake of the fire.
“It would have been seen as very inappropriate on the part of the elite in Rome,” says art historian Eric Varner. “They would have been happy if Nero had built the Domus Aurea out in the country, but to do it here in the city really was an extraordinary kind of statement.”
Tacitus was a member of this Roman elite, and whether there is a bias in his writing is difficult to know. Indeed, Tacitus was still a boy at the time of the fire, and he would have been a young teenager in 68 A.D., when Nero died. Nero himself blamed the fire on an obscure new Jewish religious sect called the Christians, whom he indiscriminately and mercilessly crucified. During gladiator matches he would feed Christians to lions, and he often lit his garden parties with the burning carcasses of Christian human torches. Yet there is evidence that, in 64 A.D., many Roman Christians believed in prophecies predicting that Rome would soon be destroyed by fire. Perhaps the fire was set off by someone hoping to make the prediction come true.

Tacitus did not have internet as a rival, so Nero’s Fake News were not available.  But let see how triathlon lives this postmodern reality full of “fake news” and people willing to believe them eagerly.  How to say things without innocence not using “fake news” is our task.  Trump banned CDC from saying evidence-based or science-based to introduce his “fake news” regarding global warming and other “fake” statements; the same for our governing bodies ruling our sports that do not read scientific journals and continue with same “neronian” politics.  Who would believe that the IOC did not know about the Russian doping? Or the bribes to get the Olympics.  ITU knows about the behavior of the FMTRI selecting international competitors and says nothing about it (see Marcas Mínimas in this blog).  From what I was informed some other Federations have followed the same behavior as the Mexican Federation.  Some members of the ITU were informed to get help from them but complaints were not understood and the behavior from Federations was not a problem (it is like Hollywood regarding sexual harrasment)

To relate our statements to the purpose of our blog, that it is in no way “bitching” about things, lets see triathlon coaching. Toni Minichiello said what we have to say (see previous post):
Remember, effective coaching is about three things; process, environment and relationships. The current award doesn’t even come close on part one; process. They are simply no-where near providing coaches with enough information. Currently it’s like strapping someone into a car for the first time, pointing out the pedals, gear stick and steering wheel before firing up the ignition and leaving them to figure it out. It’s beyond irresponsible. A comprehensive understanding of technical process should be a fundamental foundation stone for any coaching qualification”…
“Where do you start trying to fix it?”
“Understanding. Education. Like everything in life. Governing bodies need to strive to understand what effective coaching is and what it can achieve whilst many coaches, who’ve come through the current system, also need to take a look at themselves”.

Triathlon and the Art of Coaching: Toni Minichiello

Listening to interviews given by Toni prompts us to write what we have written in the past.  We are going to do it the same way as before; showing what we have written below.  Toni helps to write again.  At the end, education is like that; keep insisting until “el burro toque la flauta:”
Toni doesn’t miss a beat, “The Governing Body Coaching Award is not fit for purpose. End of. Coaches are not equipped with enough information or supported to develop the abilities they need to achieve what they’ve set out to do: add genuine value to athletes.
Remember, effective coaching is about three things; process, environment and relationships. The current award doesn’t even come close on part one; process. They are simply no-where near providing coaches with enough information.

“Where do you start trying to fix it?”
“Understanding. Education. Like everything in life. Governing bodies need to strive to understand what effective coaching is and what it can achieve whilst many coaches, who’ve come through the current system, also need to take a look at themselves”.
“In what way?”
“Coaches can forget that coaching is a giving process and put themselves at centre of things. A great coach gets satisfaction from giving. You get what you give. It’s a mind-set you must adopt to be effective. When you coach others, you’re giving to yourself through the act of giving to others”. Toni laughs, “This is getting deep. Look, as soon as you allow the focus to shift to yourself you’re lost and more importantly so is your athlete”.
On the subject of education, we contacted a facilitator of the ITU regarding the article written by Italians that could help the Federations to choose athletes in a better way for International Competitions, instead of using cut-off times in time trials as is done in Mexico without considering performance in a “real” triathlon.  He replied that they are trying to educate Federations on the subject.  He said “trying to educate” instead of looking at the problem as a Human Right violation.  The degree of ignorance is amazing in some parts of the world as Toni points out regarding the métier of a triathlon coach.

Talent selection criteria for olympic distance triathlon
ABSTRACT
Bottoni A, Gianfelici A, Tamburri R, Faina M. Talent selection criteria for olympic distance triathlon. J. Hum. Sport Exerc. Vol. 6, No. 2, 2011.
Talent Selection allows to optimize the resources available for sporting talent in order to design the best strategy to achieve top level sporting results. Because of the unknown aspects of the performance model in Olympic triathlon the TS variables and their relationship with a future performance are far-off from being identified in order to make a talent prospective study possible. Currently most triathlon federations evaluate only the juvenile performance expressed in time trials test on swimming and running. The aim of the present study was to find the most appropriate variables for the Talent Selection in Olympic Triathlon, verifying those widely used by means of a retrospective research about particular juvenile features recognized in top world triathlon athletes. The variables are considered as input variables of a Talent selection model based on Fuzzy Logic that overcome the limits of traditional models based on cut-off selection. The present findings indicate that the exclusive evaluation of juvenile running and swimming performance in order to select triathlon talent is not appropriate. Diagnosis criteria should include several other variables that should also take into account mental ability, speed of abilities development, utilization of endogenous and exogenous resources, load and stress tolerance as several leading countries have done recently. Key words: FUZZY LOGIC, TALENT DIAGNOSIS, TALENT PROGNOSIS, TALENT IDENTIFICATION, EXPERT SYSTEM

TRIATHLON AND THE ART OF COACHING

I heard a friend saying: “I do not know a coach who has crafted champions from scratch more than once.”  We went over several coaches, but we had difficulties finding coaches not just in triathlon but in any sport.  They do exist!  There are not as many as we would like to believe. I thought about Javier Gómez’ coach and believed that he is a good advisor which Gómez needs at this time of his career.  Gómez was born in Switzerland and his family learned something there that helped at this point of his life.  I thought about the Brownlees. His father is a doctor and ran competitively when in College; his mother is a former competitive swimmer.  The Brownlees have several coaches depending on the different triathlon segments. Bob Bowman grew old with Michael Phelps; he even had a house next to Michael’s.  Crafting a champion needs a coach, a family and a culture since they are born in order to be successful.  It is necessary to be at the right place at the right time when all those three ingredients are ready. Bowman worked pretty hard raising Michael from scratch, as he puts it: “Coaching Debbie (Michael’s mother) was even more difficult than coaching Michael.”  He has had a few others swimmers but none of them was really crafted by him.  The three ingredients mentioned above need the same level of education; meaning the same guidelines to follow in our thought process.

What is what we need to teach?  What makes this environment unique?  There is a good book that has a provocative name: “The Art of Thinking Clearly,” written by a Swiss, Rolf Dobelli. The book gives guidelines to learn in order to think clearly, guidelines needed if we want to be successful.  Several similar books have been written dealing with the issue of what to teach. 


George Vaillant has the Grant Study which deals with the longitudinal follow up of Harvard Graduates for decades and he mentions the Mature Defense Mechanism that make us to have some success in our lives: “Adaptation to life.”  

The Old Testament speaks about the Ten Commandments to have a “life according to divine laws;” “Divine Laws” that surely keep us out of trouble.
According to Judaism, the Aseret ha-Dibrot identify the following ten categories of mitzvot. Other religions divide this passage differently. See The "Ten Commandments" Controversy below. Please remember that these are categories of the 613 mitzvot, which according to Jewish tradition are binding only upon Jews. The only mitzvot binding upon gentiles are the seven Noahic commandments.
1. Belief in G-d
This category is derived from the declaration in Ex. 20:2 beginning, "I am the L-rd, your G-d..."
2. Prohibition of Improper Worship
This category is derived from Ex. 20:3-6, beginning, "You shall not have other gods..." It encompasses within it the prohibition against the worship of other gods as well as the prohibition of improper forms of worship of the one true G-d, such as worshiping G-d through an idol.
3. Prohibition of Oaths
This category is derived from Ex. 20:7, beginning, "You shall not take the name of the L-rd your G-d in vain..." This includes prohibitions against perjury, breaking or delaying the performance of vows or promises, and speaking G-d's name or swearing unnecessarily.
4. Observance of Sacred Times
This category is derived from Ex. 20:8-11, beginning, "Remember the Sabbath day..." It encompasses all mitzvot related to Shabbat,holidays, or other sacred time.
5. Respect for Parents and Teachers
This category is derived from Ex. 20:12, beginning, "Honor your father and mother..."
6. Prohibition of Physically Harming a Person
This category is derived from Ex. 20:13, saying, "You shall not murder."
7. Prohibition of Sexual Immorality
This category is derived from Ex. 20:13, saying, "You shall not commit adultery."
8. Prohibition of Theft
This category is derived from Ex. 20:13, saying, "You shall not steal." It includes within it both outright robbery as well as various forms of theft by deception and unethical business practices. It also includes kidnapping, which is essentially "stealing" a person.
9. Prohibition of Harming a Person through Speech
This category is derived from Ex. 20:13, saying, "You shall not bear false witness against your neighbor." It includes all forms of lashon ha-ra(sins relating to speech).
10. Prohibition of Coveting
This category is derived from Ex. 20:14, beginning, "You shall not covet your neighbor's house..." 

Bowman had a plan to develop Michael since he started, if it was not his plan it existed in the club or someplace.  We need a plan (a map) which involves the family, the environment, the coach to have some success. “It is better a bad plan than no plan at all,” it is said.  Targeting the things needed to be successful according to our time it is the book written by Rolf Dobelli; how to think clearly in this era of over information and instant gratification.  How to think clearly is needed to have a champion in this era. But we can still follow the Ten Commandments and have success as well, as long as we follow the plan to live the Ten Commandments.  Latin America is the land where the Vatican wanted to teach catholic religion again because the one practiced in these countries did not look like the catholic religion they wanted (this is called syncretism). “The map is not only NOT the territory, but it does not look like.”  A coach is needed on site 24 hours for years to have some success with one or two athletes that he develops from scratch, so “the map can look like the territory.”


What can we add to what it was said: nothing else.  It is like Nike’s slogan: “JUST DO IT,” as above.  Work on adding value to the athlete; in the process, in the family or in the environment.  Do you know how to do it? Talk to Toni, talk to Bowman, talk to Touretski, and talk to Daniels, do not aim for less.

Triathlon and Learning

We have written regarding triathlon education and talked about “Too Much Schooling and Little Education,” but the paper written by the World Bank is the first one considering this issue in detail by a World Organization, without fear and committed to the goal.  It took centuries to get to this point where a quantified research gives some information about what we need and what is lacking.  It is not a cookbook and it does not give answers to our problems but we see it as the beginning of a dialog needed to improve our performance.
“Although some countries are making progress on learning, their progress is typically slow. Even the middle-income countries that are catching up to the top performers are doing so very slowly. Indonesia has registered significant gains on PISA over the last 10–15 years. And yet, even assuming it can sustain its 2003–15 rate of improvement, Indonesia won’t reach the OECD average score in mathematics for another 48 years; in reading, for 73. For other countries, the wait could be even longer: based on current trends, it would take Tunisia over 180 years to reach the OECD average for math and Brazil over 260 years to reach the OECD average for reading….Because of this slow progress, more than 60 percent of primary school children in developing countries still fail to achieve minimum proficiency in learning, according to one benchmark. No single learning assessment has been administered in all countries, but combining data from learning assessments in 95 countries makes it possible to establish a globally comparable “minimum proficiency” threshold in math. Below this threshold, students have not mastered even basic mathematical skills, whether making simple computations with whole numbers, using fractions or measurements, or interpreting simple bar graphs. In high-income countries, nearly all students—99 percent in Japan, 98 percent in Norway, 91 percent in Australia—achieve this level in primary school. But in other parts of the world the share is much lower: just 7 percent in Mali, 30 percent in Nicaragua, 34 percent in the Philippines, and 76 percent in Mexico. In low income countries, 14 percent of students reach this level near the end of primary school, and in lower middle-income countries 37 percent do (figure O.5). Even in upper-middle-income countries only 61 percent reach this minimum proficiency.” (Pages 7-8 download)
Can you imagine giving written instructions about training in Brazil? We know what it means to give written instructions in Mexico.  Verbal instructions is not a lot different from the written ones; listening and understanding what is said it’s something that needs to be taught.  It is not the case in the majority of the countries.  When I worked at Western New York Children’s Psychiatric Center the basic teaching was to follow orders: 1) Look at my eyes. 2) Listen. 3) Repeat what I said.  In Mexico, we are deficient in following this basic education.
Triathlon is not immune to this problem.  We worked with our athletes on this basic education and we failed most of the time.  Are we bad teachers?  This is a possibility but I challenge anybody to try teaching with our population.  It is a challenge since the beginning because we are not in the “learning mode.”  The “learning mode” is teachable too; but we lost it long time ago at the level of families.  Respect for teachers and adults disappeared, and the notion that “one can always improve” is not there.  They think they already know what is needed and to venture to take a look at science is impossible.

In the year 2000 at Perth World Championship the course was measured 8k instead of 10k for the run.  A situation that happened in triathlon where math was at level of beginners, following what the World Bank mentioned.  Carol Montgomery lost the championship due to this situation.
The International Triathlon Union (ITU) sent a delegate to Perth in December 1999 to check amongst other technical issues, the distances of the run courses.  The local organising committee staged the race on behalf of the ITU who ultimately "control" the technical aspects of the event.  The ITU did not identify the discrepancy between the survey map and the CD Rom version nor did they measure the course in the days preceding the event.

It takes courage to run a World Championship to the level that were striving towards in staging the 2000 ITU Triathlon World Championship.  It has also taken courage to openly investigate the problems and then clearly communicate the findings to the media and public.  Nevertheless we do acknowledge that we also did not identify the error in the information supplied to us by the contracted surveyors.  As our lawyers have pointed out, this is information we paid for and would have expected to be correct.

The 2000 ITU Triathlon World Championship enjoyed enormous success in terms of competitor numbers, sponsor exposure and business generation, spectator attendance, volunteer contribution and economic impact on the Western Australian economy.  We would hope that members of the international triathlon community, while understandably concerned and disturbed about the incident, recognise these facts.

Well, we lately saw Jacob Birtwhistle missing one lap in the World Series event that took place in Canada.  Hopefully he is in the “learning mode,” otherwise the end of his career is around the corner.

Triathlon: Speed, Torque and Power

We have tried to explain the best way to cycle and we have used Chris Froome as an example and a flywheel:
18 juil. 2013
FROOME AND TRIATHLON TECHNIQUE II

Gregory Bateson wrote an interesting book about: “What every school child should know.” He even spoke about education:
''Science, like art, religion, commerce, and even sleep, is based on presuppositions.’’...  ''I have encountered a very strange gap in their thinking-- (referring to American Students from college freshmen to psychiatric residents, among humanists as well as scientists) that springs from a lack of certain tools  of thoughts. Specifically is the lack of knowledge of the presuppositions not only of science but also everyday life.''  (Mind and Nature, 25).
I found a very interesting conversation between bikers that illustrates what Bateson mentions and IT is the subject we should deal with regarding Froome at the Tour de France.  ANY WHEEL HAS A FLYING WHEEL EFFECT:

A flywheel weight has no effect on horsepower, the dyno charts would be identical.

Yup. A flywheel only smooths out power delivery.

You might be confusing HP with Acceleration.

Most people equate a fast reving engine with a more powerful engine.

A FWW will not change how much power is made at a specific RPM,( the 2 axis on a dyno graph)it only slows slightly how fast an engine reaches a specific RPM from an idle,it also slows how fast it will idle back down after the throttle is closed.

Just because an engine revs faster does not mean the power is transfered to the ground faster, often because of limited traction,vehicle acceleration is slower.

I run lots of extra weight on my CR and it hooks up better in most conditions.

If you are interested in a flywheel weight try one, its as easy to take off as it is to install,and relatively cheep.

I know I know I know, I have done extensive research on FWW, I dont expect to see a power gain, but rather the power curve over RPM. I would guess that without the FWW, the dyno chart would look a bit steeper in the way the power comes in over RPM. But with the FWW, would you be able to see the cure change as how the power is delivered?

something like this but real haha   
obviously this is not to scale...

oh im defiantly getting one. the idea makes perfect sense to me and im sure it will compliment my riding style. After a year or so of hearing from people about why I dont need one, I did the research and realized how much benefit they actually have. certainly characteristics I want my bike to have. cant wait to ride! I realized alot of people also dont know what it really does so the just act like its to "slow you down" haha, yeah, thats it

A flywheel weight will not change the power curve like that.  It doesn't move/change the 
horsepower and torque output relative to RPM.  If you graphed it relative to time, then the FWW will soften the curve.  That's why people run them, to lessen the hit and give the tire a better chance to maintain traction.

your'e right. like Krannie said, I was confusing HP with acceleration. It wouldn't show any difference on a dyno, but riding the bike would be a noticeable difference because of the amount of time for the acceleration of your rear wheel.

Course it's real

The difference between torque and power is that power moves the object; torque is the force apply and it is equal in number to power when the rpm is 5252:

An engine produces POWER by providing a ROTATING SHAFT which can exert a given amount of TORQUE on a load at a given RPM.

Humans pedal at 90 rpm average now a days (by looking at the Grand Tours), so we are too far from equalizing power and torque.  We have different curves related to torque-power-rpm.  Fortunately, there is an interesting paper written that studies the curve torque-rpm-power in bicycles.  What it shows is that at low rpm too much force is exerted to move the wheels compared to high cadence low torque at the same speed.  The velocity of the bicycle is the same; high torque vs low torque by changing cadence.  Also, the curve torque-rpm-power is very different by changing just 20 rpm.

Table 1
Mean pedaling cadence, cycling velocity, power output and crank inertial load of the cyclists during experimental condition. Uphill (U) vs. Flat (L)
Cycling condition                       Pedaling cadence (rpm) Power output (w) Velocity               Crank Inertia (kg/m2)         
U60                              61.1+-1.9                     325+-43                      15.0+-0.8                  42+-3.7
U80                              80.8+-1.6                     325+-39                      14.8+-0.7                  23+-1.6
L80                              82.2+-1.6                      322+-40                     38.3+-1.4                 158+-19
L100                            99.0+-1.3                      325+-35                     38.7+-1.5                 107+-15


What we see is that the torque does not convert "fully" to power at low cadence and it is seen in the crank inertia load; we waste energy using that much torque to move something at speed that could be accomplished with less torque.  The flywheel plays a role in the equation.
