A importanciada ciência do esporte na formação de atletas olimpicos

  • Posted on:  Thursday, 20 June 2013 13:16

O corpo humano é uma máquina surpreendente! Se você levantar, passar pela porta e caminhar em torno do quarteirão, quase todos seus sistemas serão acionados, ocorrendo incontáveis eventos fisiológicos coordenados pelo cérebro controlando a passagem do estado de repouso ao exercício.

Criando a rotina de se exercitar diariamente, durante semanas ou meses, e aumentar gradualmente a duração e a intensidade de sua caminhada, você verá uma melhora do desempenho do organismo. Com isso, pode-se afirmar que o treinamento é sempre gradativo, levando o organismo a se adaptar a estímulos cada vez mais fortes, seja nível de volume ou de intensidade do treinamento.

Chegar ao nível olímpico não é tão simples. Por trás da formação de um atleta olímpico existe uma equipe formada por uma série de profissionais competentes que intervêm em vários aspectos como os nutricionais, técnicos, táticos, psicológicos, fisiológicos e biomecânicos. Para chegar ao nível que os atletas olímpicos atingiram, a ciência do esporte refinou seus saberes em relação aos conhecimentos gregos do passado. Os cientistas do esporte e técnicos têm hoje um conhecimento muito mais aprofundado e fundamentado em pesquisas científicas para ajudar atletas a controlarem seu desenvolvimento muscular e metabólico nas 29 modalidades praticadas nas olimpíadas.

O acesso a tecnologias mais avançadas, como tênis que realizam uma série de cálculos por segundo para adaptar o pé ao solo em que se encontra, roupas que diminuem o atrito com a água ou ar e várias outras novas tecnologias empregadas, melhoram a performance do atleta durante a prova. Outro fator muito importante é sem dúvida a parte psicológica do atleta, a qual estudos já comprovaram ser fundamental para a realização no rendimento do atleta durante a competição. Psicólogos do esporte hoje têm o conhecimento de que qualquer fator psicológico pode mudar o rendimento de um atleta durante a prova, como a ansiedade gerada por uma noite mal dormida ou a motivação para a final do dia seguinte.

Os atletas olímpicos também contam com profissionais da área de biomecânica, engenheiros e técnicos para poderem alcançar marcas jamais alcançadas antes, chegar a vitórias e superar recordes. Nesse aspecto, o Brasil conta com Centros de Excelência Esportiva (Cenesp), que são laboratórios destinados ao estudo dos esportes e é onde os cientistas dão suporte científico para a melhoria do treinamento do atleta. Um deles está localizado na Faculdade de Educação Física da Universidade de Brasília (UnB). ??Esses laboratórios contam com uma série de aparelhos que diagnosticam a performance do avaliado.

Um exemplo é o ergoespirômetro, que tem como função avaliar índices fisiológicos como limiares ventilatórios, capacidade cardiopulmonar e tolerância do esforço máximo. Esses instrumentos de alta precisão tecnológica, como ergômetros para braços e pernas, medidor de ácido lático sanguíneo, analisadores dos gases expirados e outros equipamentos portáteis são utilizados para avaliação em laboratório e no campo, respeitando a especificidade da modalidade praticada. Após a realização de testes, perguntamo-nos como essa “parafernalha tecnológica” ajudará atletas olímpicos a superar seus índices?

A evolução da ciência do esporte contribuiu imensamente para o desenvolvimento tecnológico de equipamentos de avaliação e acessórios esportivos, suplementos alimentares proporcionando o desenvolvimento científico de informações importantíssimas para que o técnico realize o melhor tipo de treinamento para seu atleta alcançar níveis de rendimento máximo. Esse casamento entre a ciência e a prática faz com que o cientista do esporte e o técnico tornem-se aliados na criação de um atleta de ponta.

Existem estudos que mostram o crescente interesse de pesquisadores e profissionais na busca de evidências do método Pilates aplicado em diversos âmbitos par auxiliar os atletas olímpicos. Desde a determinação do custo energético de sessões de Pilates (OLSON et al., 2004), registro da atividade eletromiográfica de músculos envolvidos em seus exercícios específicos (ESCO et al., 2004), comparação entre os seus efeitos sobre a força, flexibilidade e composição corporal aos de um programa de treinamento contra resistência convencional (OTTO et al., 2004), mapeamento de respostas cardiovasculares em alguns de seus exercícios (SCHROEDER et al., 2002), ação sobre o equilíbrio (HALL et al., 1999), efeitos sobre a dor lombar (GRAVES et al., 2005), até mesmo seus efeitos sobre a velocidade de atletas (SEWRIGHT et al., 2004), capacidade e habilidade de salto em ginastas de elite (HUTCHINSON et al., 1998) e postura de bailarinas (MCMILLAN et al., 1998) são alguns dos exemplos dos diversos estudos que têm sido empreendidos.

Ainda assim, há uma enorme lacuna que somente será preenchida com o investimento em novos estudos. Considerando a expansão do método no ambiente fisioterapêutico, do condicionamento físico e do treinamento de atletas, necessário se faz a determinação de meios de melhor controle e do estabelecimento de cargas, caracterização da ação e do envolvimento muscular nos seus diversos exercícios, efeitos de um programa básico, intermediário e avançado sobre parâmetros da aptidão física, atuação sobre desvios posturais, dentre diversos outros.

Por traz de um grande atleta existe muita tecnologia, ciência e pesquisa.

    There is certainly not in society that is going
    to make a woman feel beautiful like a high quality tote. There are amazing handbags which usually
    made help to make the clothes. The one frustrating thing about designer handbags is that are very expensive but the quality is unlike anything calm ever think about it.

    Hermes handbags are legendary. These amazing handbags have been with us for many years but
    the grade of has always stayed changing.
    The Hermes company started with saddle bags in 1837 and expanded from there.
    Hermes features the best known handmade handbags that are available today.

    Most men and women will not notice that creating your personal colloidal silver
    with a substantial-excellent colloidal silver generator is truly
    exceptional to getting industrial brands. Here
    are seven factors why building your own colloidal silver presents you a
    spectacular edge in excess of the use of industrial manufacturers.


    Reason #1: You can make colloidal silver so inexpensively you can virtually manage to bathe in it!



    That is ideal. When you make your have colloidal silver, you may under no
    circumstances get ripped off once more by greedy colloidal silver distributors.
    A regular 4-oz. bottle of colloidal silver contains only about 6 to 12 cents value
    of actual silver particles. Yet they charge you up to $thirty
    for that tiny bottle. That's a 2,400% mark-up on every single bottle!


    But when you make your own colloidal silver you can do so for literally a handful of pennies per quart.
    Your only true expenditures are the distilled h2o (about seventy nine cents a gallon at Wal-Mart),
    and the moment each and every 12 months or two you can almost
    certainly have to spend somewhere around $25
    to change the set of pure, .999 wonderful silver wire that
    normally will come with your generator when you buy just one.

    Yet with a substantial-high-quality colloidal silver generator, a one
    established of pure silver wire costing you about $25
    will allow you to deliver over $24,000 worth of colloidal silver (no kidding!) in excess
    of the class of a 12 months, dependent on normal health and fitness
    foodstuff retail store rates of up to $thirty
    for a small 4-ounce bottle!

    So when you component in the cost of the silver wire, the small total of electrical power
    essential to operate the generator (which is frequently less
    than what is actually expected to run a little Christmas tree gentle bulb)
    and the expense of the distilled drinking water, it arrives out to about 36 cents a quart or a lot less to make a high-quality colloidal silver answer
    that just blows away the standard, commercially
    well prepared models. Which is about as close to generating colloidal silver
    for "no cost" as you can get!

    Review that to professional brand names costing up to $thirty for a small
    four-ounce bottle, and you'll see why we say that when you make your personal colloidal silver,
    you can practically pay for to bathe in it. In actuality, all you have to
    do is brew up a one particular-quart batch (whole price tag: 36 cents) and toss it into
    your bathwater prior to bathing. Its comforting and invigorating effects on the pores
    and skin are past examine!

    Purpose #2: You won't get ripped off with diluted colloidal silver alternatives!


    In new assessments only about 43% of the bottled colloidal silver products analyzed contained the precise concentration of
    silver mentioned on the label. Most business brand names tested contained considerably less silver
    than said on the label. And some contained no silver particles at
    all!

    In truth, just one maker who got caught providing colloidal silver with no actual
    silver particles in the remedy afterwards claimed he experienced
    put the "vibrational pattern" of the silver in the h2o, and as a result felt he experienced no have to have to insert actual
    silver particles. Hey, that is great with me, as extensive as the products was advertised and labeled as that contains no
    precise silver particles. But never anticipate also significantly from a products like that in conditions of aiding your health and fitness and very well-staying!



    Now never get me mistaken: I'm a large fan of
    homeopathy. But even homeopathy begins with the real
    compound, and then will take it as a result of a multi-action dilution method.
    These guys later admitted that they "translated the vibrational sample"
    of silver particles into audio (sure, tunes) and then transferred the very same sample into the water by playing the audio as the water was being bottled.
    Yes, they named this "colloidal silver." But perhaps
    they should really have named it "musical h2o." As Sponge
    Bob states, "Excellent luck with that!"

    This is why it is so important to make your own colloidal silver.
    When you make your have colloidal silver with a
    large-top quality colloidal silver generator, you management the concentration.
    Based upon which variety of colloidal silver generator you purchase,
    you can make five ppm, or 10 ppm, or 20 ppm, or even hundreds of ppm if you desire.
    But you normally know specifically what you are finding, each individual time you make it.
    You are not able to get scammed, unless of course
    you approach on scamming oneself!

    The base line is that in purchase to steer clear
    of staying ripped off by greedy distributors, you have to handle the usually means of colloidal silver creation. And
    which is just what takes place when you personal a superior-high-quality colloidal
    silver generator. You come to be the colloidal silver
    company...which allows you to develop the focus you want!


    Motive #three: The freshness and efficiency of your colloidal silver is usually in your palms rather
    than some vendor's hands!

    By making your own colloidal silver fresh new, you
    can rest assured it has not been sitting down in some
    warm warehouse for six months right before being delivered
    to your area overall health food stuff keep, exactly where it sits on the shelf for an additional six months dropping potency ahead of it is sold
    to you. When you make your personal, it is contemporary every time.
    The electrical cost on just about every particle of silver is at its peak.


    This is a dirty small secret most professional sellers will
    not want to explain to you: to get the greatest prices, folks
    promoting business makes have to buy huge portions of colloidal silver at a time from a production plant.

    These large portions are generally marketed to them in fifty
    five gallon drums that are afterwards shipped to a deal production laboratory
    wherever the colloidal silver is bottled up in these small 4-ounce or eight-ounce bottles, and
    then transported again to the vendor in situations of 12 or 24 bottles.


    This inventory then sits in a warehouse, through summer season warmth and winter season cold, although it is slowly
    and gradually becoming marketed off, case by case, or bottle by bottle to the different overall health food stuff retailers or world wide web sellers, who in transform market it to colloidal silver
    consumers like you.

    Given that all electrical prices in nature dissipate
    more than time, and do so even speedier when uncovered to hot or chilly, you have no strategy how much electrical
    demand is remaining on the silver particles after you've got last but not least ordered a bottle.

    Why? Because you have no strategy how lengthy that colloidal
    silver sat in a fifty five gallon drum ahead of being bottled...or how very
    long that bottle sat in a sizzling or cold warehouse...or how
    long it sat in a UPS truck in the depth of winter or the heat of summer throughout
    cargo...or how extensive it sat on a store shelf ahead
    of you acquired it.

    But when you make your own colloidal silver with a large-excellent colloidal
    silver generator, you can make it contemporary every single time for
    just pennies for each batch. You in no way have to be concerned about no matter if or not the product
    or service was presently 5 months old, or ten months previous,
    or fifteen months aged or even 24 months outdated when it
    was ultimately marketed to you.

    You can make it contemporary each time you will need some,
    or you can just throw out batches at 3 months, 6 months, or
    a 12 months, or no matter what makes you comfortable. (I toss mine out following
    a year, even if there is no evidence of silver particles settling out of suspension. But I never waste it.
    I toss it into our scorching tub for included safety
    from microbial expansion, or set it in the dog's
    drinking water bowl, or even use it in the laundry to support preserve bedding, towels, dishrags and underclothing
    clean and microbe-no cost longer.)

    Certainly, throwing absent colloidal silver is a thing a person may well be unwilling to do if you have paid
    out up to $30 or more for a little 4-ounce bottle from a business vendor.
    But when you make your own superior-high quality colloidal silver for about thirty-six cents
    a quart, it is no massive offer at all! If you might be uncertain of the freshness or efficiency of a
    batch you've got designed formerly, toss it out into the backyard (yes, vegetation really like it) and make a fresh new new
    batch for yourself for just pennies, and use that alternatively!


    Reason #4: You are going to have no hidden fillers, dyes, protein or gelatin coatings,
    or other additives in your colloidal silver!

    When you make your have colloidal silver, you get rid of all hidden fillers, dyes, protein coatings, gel coatings
    or other additives and "stabilizers" used by commercial suppliers.
    You get pure colloidal silver each and every time, because you're in regulate of the overall colloidal silver creation approach.


    Believe it or not, quite a few unscrupulous business colloidal silver suppliers actually include substances to their colloidal silver products that you should not
    show up on the label. For illustration, some increase yellow foodstuff coloring.
    Which is due to the fact they know that amateur colloidal silver
    buyers are beneath the misguided effect that "golden-coloured" colloidal silver has far more potent
    infection-battling traits. Almost nothing could be additional from the reality, of training course.

    There has never ever been a review demonstrating that golden-coloured
    colloidal silver is exceptional in any way to colloidal silver that is
    crystal crystal clear. But this very little piece of common "wisdom" persists, and some professional colloidal
    silver distributors attempt to capitalize on it by introducing yellow foods dye to their product, to make it appear golden-colored.


    The trouble is that any time you incorporate an component to your colloidal silver -
    whether or not it is any of the well-known additives these as salt, baking soda, MSM,
    aloe vera or even foods dye - you create a affliction in which the
    silver particles begin to bond collectively in significant clusters all-around the additive.
    Which is simply because the additive alterations the electrical possible of the silver particle, enabling particles that would normally repel each other
    in the option to bond with every single other instead, forming large particle
    clusters. This typically leads to premature precipitation of the
    silver particles (i.e., the silver particles start out to tumble out of
    suspension and coat the base of the bottle), not to point out the actuality
    that you are ingesting overly massive silver particle clusters as an alternative of the significantly extra effective personal silver
    micro-particles you definitely require for
    optimum infection-fighting ability.

    In other documented scenarios, colloidal silver suppliers have added protein or gelatin coatings to their silver particles,
    ostensibly in get to support stabilize them in the option. The ensuing issue is that all those coatings so fully go over
    the silver particles that microbial advancement commences to spread on the outer
    shell of the coating. The silver particles can not get rid of the
    microbes due to the fact they are coated so carefully by the gelatin or protein! And
    thus you actually get microbial growth within of a colloidal
    silver products!

    But that only are unable to happen when you make your possess colloidal silver with a high-top quality colloidal
    silver generator. Each individual of the virtually billions of sub-microscopic
    silver particles in your resolution are "raw," indicating they are not coated by any material or bonded to any substance.
    It is just pure silver, and absolutely nothing else.
    And consequently microbial progress simply just are unable to consider put in the answer.


    Cause #five: You can expect to often take pleasure in instantaneous accessibility to colloidal silver when you want it the most!


    If you have been utilizing colloidal silver for even a reasonable volume of time, you've most likely seasoned a predicament in which you actually essential some swiftly,
    but did not have any helpful. So maybe you experienced to leave the
    home in a mad sprint, and push to your area wellbeing foods keep to get some, hoping they still had
    your favored brand name in stock. Or you experienced to order it over the internet and hold out a 7 days or for a longer period to acquire it.


    But with a large-good quality colloidal silver generator in your home, you
    are going to hardly ever yet again have to stress about managing out of colloidal silver at an inopportune time, these as when you are
    coming down with a chilly, or one particular of your small children have picked up a tummy bug, or you go out for supper and appear home with a horrible
    circumstance of foodstuff poisoning.

    Howdy! I realize this is sort of off-topic but I needed to
    ask. Does operating a well-established website such as
    yours take a lot of work? I am completely new to running a blog but I do write in my
    journal daily. I'd like to start a blog so I can share my experience and thoughts online.
    Please let me know if you have any kind of
