¿Te lo crees si te digo que puedes quemar más grasa con este tipo de entrenamiento que con el que se piensa la mayoría de gente?

Seguramente te habrán contado que para quemar grasa debes hacer un trabajo cardiovascular de más de media hora a una intensidad moderada. Pues bien, ahora no hace falta que te tires horas y horas en la cinta. Con el HIIT podrás conseguir los mismos resultados en menor tiempo.

Como ya te comentamos en el artículo anterior de “COMO USAR TU PULSOMETRO SEGÚN EL OBJETIVO ” cuando realizamos ejercicio aeróbico a una intensidad moderada  y nos encontramos en el umbral del 60% – 70% estaremos utilizando como energía, además del glucógeno muscular, las grasas. Teniendo esto en cuenta, muchos podéis pensar que la mejor forma de perder grasa es realizando ejercicio cardiovascular a intensidad moderada durante un largo periodo de tiempo, pues no exactamente. Existe una forma de realizar ejercicio de forma quefavorezcamos la quema de grasa a la vez que fomentamos el aumento de masa muscular, este tipo de entrenamiento es el que llamamos HIIT (High Intensity Interval Training) o entrenamiento en intervalos de alta intensidad.

El HIIT consiste en intercalar periodos de entrenamiento cardiovascular en alta intensidad a un 80% ~ 90% de nuestra Frecuencia Cardíaca Máxima (FCmáx) seguido de periodos cortos de ejercicio cardiovascular a una frecuencia moderada, entre un 50% – 60% de nuestra FCmáx. Generalmente suele seguir una proporción temporal de 1:3 a la hora de intercalar los intervalos de intensidad elevada con los de intensidad moderada.

El HIIT puede realizarse en distintos aparatos,  nosotros personalmente lo hacemos en la cinta de correr, pero también se puede realizar en la elíptica, en la bicicleta, en la piscina, saltando a la comba (aunque en algunos casos creo que es mas difícil controlar las pulsaciones). Si tenemos un buen pulsómetro, teniendo bastante experiencia y contando con buen tiempo, se puede realizar el HIIT en la calle sin ningún problema.

Los beneficios del HIIT suceden gracias a que con estos cambios de intensidad conseguimos metabolizar la glucosa (Azúcar en sangre) de forma más efectiva, provocando que nuestra resistencia y nuestro rendimiento mejoren, además de favorecer la quema de grasas. Pero no solo esto, gracias al HIIT, mejoramos nuestro VO2 máx(Volumen de Oxigeno Máximo), ganando así mayor resistencia aeróbica.

Además de esto, el HIIT mantiene el aumento de nuestro metabolismo durante un mayor espacio de tiempo, es decir, provoca que en estado de reposo, nuestro cuerpo queme más kcalorías, y si lo que buscamos es perder grasa, esto favorecerá aún más nuestro objetivo.

Si estuvierais  en la fase de ganancia de volumen muscular, el HIIT al realizarse en un corto espacio de tiempo (se recomienda que el HIIT sean sesiones cortas de no más de 20′ o 25′), favorecen el anabolismo muscular.

Hay que tener en cuenta que el cardio ayuda a aumentar el metabolismo incluso cuando ya se ha acabado de realizarlo, y algo muy interesante de meter picos de intensidad en nuestra rutina cardiovascular es que ese aumento en el metabolismo dura más tiempo que si no se realizan(en torno a una hora más después de acabar el cardio).

Conclusiones del HIIT sobre el cardio moderado:

Favorece la quema de grasas en mayor proporción.

Mantiene nuestro metabolismo más activo durante más tiempo.

Mejora nuestra capacidad aeróbica aumentando nuestro nivel de VO2 máx, con lo cual, aumenta nuestra resistencia.

Favorece la ganancia muscular.

Debemos tener en cuenta también que el HIIT somete a nuestro organismo a un esfuerzo de trabajo elevado y no es recomendable hacerlo más de 2 o 3 veces por semana, dejando algún día de descanso entre ellos.

Un ejemplo de HIIT sería el siguiente:

– 5 minutos de calentamiento al 50% ~ 60% FCmáx

– 9 series de : 30 segundos al 80% – 90% FCmáx  seguido de 90 segundos al 50% – 60% FCmáx

– 5 minutos de vuelta a la calma al 50% ~ 60% FCmáx

    'Megab***h' has become the latest outrageous Countdown word to crop up.



    And Rachel Riley left host Anne Robinson 'astonished' at the word's mere existence as she spelled it out on the
    board on Monday's show. 

    Rachel took to Instagram to post a still
    of the moment, stood next to the word, suggesting it could be her new profile picture.










    'New profile pic?' 'Megab***h' has become the latest outrageous Countdown word
    to crop up

    Current contestant Florence first suggested seven-letter
    word 'megabit', with Dictionary Corner revealing the 'C' and the
    'H' could be tacked on the end for 18 points.

    'Really? That's astonishing! Perfectly acceptable for this time in the afternoon?' host Anne asked.

    They then joked that it would make a good band name too.

    'As long as they're all women!' Anne noted. 

    Rachel was seen stifling a laugh in another recent episode of the Channel 4 quiz
    show as a contestant declared he word 'hooters' for seven points
    - which is North American slang term for a woman's breasts




    What the...? Rachel Riley left host Anne Robinson 'astonished' at the word's mere existence as she spelled it out on the board on Monday's show





    Far from it: Rachel took to Instagram to post a still of the moment, stood next to the word, suggesting it could be her new profile picture 














    Smirking: Rachel stifled a giggle on Countdown as
    a contestant spelled out 'hooters'

    Rachel, who is expecting her second child with husband Pasha Kovalev, appeared to hold back a grin when the camera switched to her
    after the rude word had been placed on the board. She cradled her baby bump and turned to look
    the other way. 

    Susie Dent, the show's resident lexicographer, added that there were 'quite
    a few seven [letter words]', with the other contestant offering the word 'shooter'.    

    This humorous moment comes after Rachel was left red-faced when a guest spelled out 'cra**ed' and asked
    the team: 'Can you have c****ed?' 

    However, the exact same word accidentally cropped up for former host Carol Vorderman 22 years ago.
    She starred on the show from 1982 until 2008.  








    Rude word: The tickled TV star, 35, was faced with placing the word - which is North American slang term for
    a woman's breasts - on the board for all to see















    Awkward: Another risque word popped up the week before 'hooters'









    Spot the difference: The same thing happened to former host
    Carol Vorderman back in 1999

    In 1999, viewers were left stunned after contestant Dennis Raishbrook spelled out 'c*****d' on the board in an unfortunate word blunder,
    leaving the studio in giggles. 

    During the crude episode last week, Susie Dent explained the word
    was acceptable, saying: 'Yes, c*****d, also to c**p out of a game of c**ps, gambling game, is to make
    a losing throw, absolutely fine.'

    Rachel could be seen smirking as she looked at the board before getting on with the rest of the
    show. 









    Rude: The pregnant star was left red-faced when a guest
    spelled out 'c****ed' on the board

    These haven't been the first instances a rude word has found
    its way onto the Countdown board.

    In December, Rachel was left embarrassed after she spelled out the words 'foreskin' and 'stonker'. 

    Fans flooded Twitter when the episode aired, with users marvelling over
    Rachel's giddy response, and also noting fellow stars Nick Hewer and Susie's less than overjoyed
    reaction at the hilarious twist.

    In an episode from July of 2019, two contestants scored points with a curse word.









    Show: The contestant seemed unsure about
    his word choice and asked the team: 'Can you have c****ed?'









    Acceptable: Susie Dent explained the word was acceptable,
    saying: 'Yes, c*****d, also to c**p out of a game of c***s,
    gambling game, is to make a losing throw, absolutely fine'

    Rachel was left raising her eyebrows as she was tasked with spelling out 'w***ers', which was blurred and beeped out when the show aired.


    Asked what words they had managed to make out of the random letters, contestant Rob said:
    'A bit of a rude seven,' while his opponent James added:
    'Yeah, I have got a certain seven as well.'

    As it transpired that both men had come up
    with 'w***ers', comedian Rory Bremner - who was in Dictionary Corner with Susie - was left stifling his giggles as he mused:
    'I would have preferred swanker.'

    Flustered host Nick then asked Susie if there were any polite
    alternatives they could have chosen, with Susie revealing
    they could have picked 'workman' or 'workmen'. 








    Ahem! In December, Rachel was left embarrassed after she spelled out
    the words 'foreskin' and 'stonker' 

    In January of the same year, when Rachel was asked to make words out of the
    letters 'GESULIPNK', she sneakily spelled out the
    word 'spunk'. 

    The audience and comedians all erupt in laughter before applause
    broke out. 

    Rachel and her husband Pasha Kovalev are preparing to welcome their second child
    into the world and already share their daughter Maven, who is 18 months
    old. 

    It comes after Pasha recently revealed he is
    trying to protect his wife from cruel online comments sent by internet
    trolls.

    As the dancer and Rachel are expecting their second child,
    Pasha said he is 'trying to protect her as much as
    I can by providing a safe environment at home'.








    Oops: In January 2019, Rachel was left raising her eyebrows as
    she was tasked with spelling out 'w***ers', which was blurred and beeped out when the show aired







    He added: 'That's all I can do and try to direct her attention to the good things.'

    Speaking to OK!, the Strictly star added he steers away from cruel online comments aimed at Rachel, admitting: 'I never look at comments online and Rachel is trying to get a point across
    about racial abuse or domestic violence and she gets back very ridiculous messages.


    'People completely miss the point and speak about something irrelevant.'

    His comments came a month after he revealed he worries how trolls' hurtful messages could
    affect their unborn baby.

    Speaking to The Mirror, he said: 'I definitely can see how it
    stresses her. The smallest stress affects how the baby's development is going.'








    Cheeky: In January of the same year, when Rachel was asked to make words out of the letters 'GESULIPNK', she sneakily
    spelled out the word 'spunk' 







    The performer added that he hates seeing hate flourish online where there is less accountability.


    He explained: 'If you come up to someone on the street and tell
    them something like that, you're probably going to get some sort of repercussion.

    'Online there's a limited amount of repercussion, and it opens a floodgate.
    It should be stopped.'

    Rachel previously revealed the stress of receiving hateful messages online stopped her first daughter,
    Maven, from kicking when she was pregnant with her

    The Countdown star had been a vocal critic of Jeremy Corbyn and the anti-antisemitism
    row in the Labour Party and received horrific messages online as a result.









    Couple: It comes after Rachel's husband Pasha Kovalev recently
    revealed he is trying to protect his wife
    from cruel online comments sent by internet trolls
