La dégénérescence maculaire liée à l’âge (DMLA) est une maladie dégénérative de la rétine qui affecte la macula, partie centrale de la rétine, entraînant une perte progressive de la vision centrale. Elle peut être classée selon deux formes d’atteinte à savoir une forme humide et une autre sèche.

La forme humide (ou exsudative) est considérée comme la plus sévère vu qu’elle provoque la cécité en plus ou moins quelques mois tandis que la forme sèche (ou atrophique) évolue très lentement, néanmoins, elle est dénuée de traitement jusqu’à ce jour.

Dans ce contexte, des chercheurs de l’Université de Harvard ont découvert, en collaboration avec leurs collègues de l’Université de Crète, qu’un médicament à base de statines habituellement prescrit pour traiter le cholestérol, pourrait soigner la DMLA sèche lorsqu’il est pris à forte dose.

En effet, l’acuité visuelle d’un patient atteint aussi bien de cholestérol que de DMLA se serait améliorée après qu’il ait suivi un traitement avec l’atorvastatine à raison de 80mg/jour durant plus d’une année.

Les scientifiques ont dés lors décidé d’étendre leurs recherches en faisant appel à 23 personnes de plus de 50 ans qui se sont portées volontaires pour tester cette nouvelle méthode. À l’issue de l’étude, dix personnes ont noté une amélioration significative de leur acuité visuelle.

Bien qu’ils soient prometteurs, les résultats de cette étude ne sont pas très concluants. C’est pourquoi, les chercheurs ont décidé de conduire leur étude sur un plus grand échantillon afin de s’assurer de l’efficacité de cette méthode contre la DMLA sèche. Attendons de voir les résultats de la nouvelle étude.

    Unilateral dumbbell bent-over rows are a fantastic method to cross-train your pull-ups because they assist establish and tackle muscular imbalances.
    The Pendlay row, however, is often programmed as an help exercise for the deadlift.
    That’s mainly as a result of the exercise is so much more durable on the spinal erectors than the
    classic barbell row. The Pendlay row is a variation of the barbell
    row named after veteran weightlifting coach Glenn Pendlay.
    Barbell rows aren’t necessarily better than lat pulldowns, nor are
    pulldowns better than rows.
    Named after US weightlifting and powerlifting coach Glen Pendlay, this is a
    superb exercise for constructing power and muscle measurement.
    These three will do just nice if you would like to use
    your dumbbells to re-create workout routines much like the seated cable row.
    The Pendlay Row is a variation of the bent over barbell row that makes use of a extra
    horizontal torso place to focus more on the lats and less on the trapezius.
    The underhand barbell row is a variation of the standard barbell row that enables for a barely
    higher range of movement when the palms are going through forward.

    This exercise requires the core, glutes and legs to stabilize the physique as
    you might be lifting.
    Being a personal coach with a diploma in fitness
    and health promotion and background in diet I
    even have been actively training myself for over 10
    years now and have been interested in it even longer.

    One factor I actually have realized over the years is it would not matter what you might be doing by way of training
    or exercise it always leads again to one key factor and that is
    restoration. As A Result Of all you want is a towel
    this exercise may be carried out anywhere.
    For a visible guide to performing the Meadows row, here’s a useful video from John Rusin.
    As with any unilateral exercise, it is good to begin in your weaker aspect and
    match the work with your stronger or extra dominant
    arm. Doing so will help cut back muscle imbalances quite
    than exacerbating them. To get the full advantage of this exercise,
    move by way of a full range of movement and keep away from using momentum to carry the dumbbell.
    This exercise is carried out on a machine that lets you row the load in direction of your chest.
    You can use a variety of grips, including overhand, underhand, and
    impartial. This exercise is performed with your back supported on a
    weight bench, which takes the pressure off your lower back.
    This variation of the bent-over barbell row is carried out with a useless
    cease at the backside of every rep.
    Make positive you may be on flat ground and avoid
    swinging your arms – keep your travel regular. As A Outcome
    Of it entails such heavyweights, sustaining proper kind (basic form remains to be critical) while
    performing this exercise is troublesome. Your chest should keep up a correspondence
    with the bench the entire time, and you should preserve a powerful body.
    This train permits you to isolate the mid-back muscles as opposed to letting your decrease again do the work.
    A frequent mistake is arching your back, which might negate the above advantages.

    If you wish to kick your single-arm row exercises up a
    notch, this could presumably be the exercise for you. If you’re questioning tips on how to fit these seated
    cable row alternatives into an entire, well-rounded routine to construct lean muscle, check out
    our beginner weightlifting routine. They should somewhat replicate the vary of motion and muscle recruitment of the cable row.

    Nothing will replace the soundness of the cable row, so take note of form.

    Even so, it additionally engages a couple of other muscles much like seated cable rows like deltoids, forearms, biceps, and trapezius.
    Incorporating the landmine row into your workout routine provides variety to
    your upper physique training while providing a different
    engagement angle than traditional rowing exercises. Enhance
    your power and muscle growth with this efficient variation that
    targets key muscle groups in your back and arms.
    When concentrating on this area of the back, the lats typically reply better to vertical pulling workout
    routines such as the lat pulldown. Pull ups
    are a difficult compound exercise that’s mainly going to work the muscle tissue of your higher back; particularly, the lats serving to
    you to construct a wider again. Apart from activating your mid-back
    muscular tissues, this efficient exercise may also
    work your glutes and improve shoulder and core stability.
    The Gorilla row is a good muscle constructing train that’s going to activate pretty
    much your whole higher again muscular tissues in addition to your biceps and posterior deltoids using just a pair of kettlebells.

    Maintain your shoulders pulled down and back all through the exercise to avoid engaging
    your traps and rhomboids. Actively retracting your shoulder blades protects your shoulder joint and ensures you target the correct muscle teams.
    Weighted rowing variations just like the unilateral dumbbell bent-over row
    build a stronger again.
    One mistake you must keep away from when performing the one-arm DB bent-over row is swinging
    your arm instead of maintaining a sluggish and regular vary of movement.
    You can vary the burden; the machine is designed to isolate
    your upper-back muscle tissue. Hold the TRX handles while maintaining a diagonal position and row your self as much as the handlebars.
    Moreover, strengthen your core, so that you don’t fall again while performing the exercise.

    Dumbbell pullovers are more of a seated cable row substitute
    if you’re excited about isolating your lat muscular tissues.
    Other muscles like your biceps, core, shoulders, and so
    forth. is not going to should do much. This seated
    cable row alternative is completed with one facet at a time, unilaterally.
    This can help you avoid using one arm more than the opposite which can lead to muscle imbalances.
    T-bar rows supply very comparable benefits as seated cable rows but they are
    going to be barely more difficult in your lower back and
    erector spinae. The major draw back of replacing
    seated cable rows with inverted rows is that you are not ready
    to use that much external resistance.
    It is designed for explosive energy engagement
    and discourages ‘cheating’ via momentum usage. This makes it an exceptionally efficient movement for enhancing muscle progress and
    boosting strength ranges. When performing the T-bar row, position your toes at shoulder width and barely bend your knees.

    Ensuring that you have a straight again is crucial for spinal
    protection while executing the lift.
    When it comes to building strength and muscle in the upper back,
    the barbell row is amongst the go-to workouts for many lifters.
    The barbell row is an efficient strength coaching train that primarily targets the muscular tissues in the upper back and core region.
    Upright rows are extra of an train in your shoulders than they’re in your again.
    Nonetheless, if you don’t have access to a barbell or want to change issues up this is when discovering options to barbell rows is important and alternatives that can provide you similar results.

    The Yates row named after well-known classic bodybuilder Dorian Yates is an easy variation of
    the bent over barbell row which Yates attributes to the spectacular improvement of the
    muscle tissue in his back. The inverted row is a great train for constructing a robust back without the necessity
    for heavy weights or fancy equipment. To carry out this train, you’ll want a horizontal bar that can help your body weight, like
    a pull-up bar or a Smith machine bar. The bent over row is an efficient method to
    improve posture, strengthen the again muscles, and
    improve total higher body power. Get the most out of this
    exercise by paying close consideration to your posture.
    Avoid leaning back an excessive amount of as you pull the handle
    into your torso to make sure your back and rear delts are doing
    all of the work.
    The lats, rhomboids, trapezius, rear deltoids, and spinal erectors are beneath rigidity during this exercise, serving to to build not only a stronger back, however stronger deadlifts and back
    squats. If you need to use your entire physique to twist and rock the weight up then the dumbbell is too heavy.

    The most popular alternative to Barbell Rows might
    be the One Arm Row. The One Arm Dumbbell Row is nice if you
    have dumbbells however no barbell or if you’d like a rowing
    movement that allows for extra low again support. Bent Over Barbell Rows are one of the best
    workouts for constructing an even bigger and stronger back.
    Utilizing a barbell permits you to work heavy and bent rows will
    problem your whole back from high to backside. Suspension coach
    rows utilize suspension trainers to target the back muscle tissue and improve back energy and stability.

    In pursuit of crafting the ultimate bent over row approach and attaining formidable higher physique energy, barbell bent over rows
    take center stage alongside complementary movements similar to pull ups.
    It’s not just brute energy that bent over rows bestow upon their practitioners.
    By supporting muscle tissue crucial for backbone alignment and shoulder
    retraction, these workout routines contribute in course of standing upright extra naturally.
    They provide increased energy expenditure that is
    beneficial for weight management while concurrently strengthening.
    Having a solid back exercise just like the barbell row in your exercise routine is
    important, but having alternatives up your sleeve
    can help make your exercise even higher.
    Moreover, this train doesn’t load the lower back and could
    be useful for avoiding injury. Novices and advanced lifters can profit from this exercise by promoting recovery
    and avoiding spinal loading. I would highly advocate
    throwing on a pair of Versa gripps to make this exercise a lot easier.
    Regardless of whether or not or not you may have other rows in your routine,
    this may be a useful addition.
    Fortunately, plenty of substitutes are available to replace the bent-over row.
    These substitutes not only target comparable muscle teams but
    also supplies comfort to the back. An wonderful activity before progressing to
    heavier, longer, and more intense training sessions.
    The TRX row promotes strength and mobility and ought

    the lower again.
    These muscles are positioned within the higher again, primarily answerable for shoulder blades’ retraction, protraction,
    and stabilization. You ought to emphasize these muscle tissue
    extra if you wish to develop a cobra back. Heather Jacques

    Grand Valley State University with a Bachelor
    of Science in Athletic Coaching.

    There are also exercises that are beginner-friendly
    as nicely as movements that can problem even superior lifters.
    The fastened bar path helps maintain type, permitting you to concentrate on explosive lifts
    from the ground to target the back muscular tissues successfully.
    You can even add other again workout routines with a Smith machine such because the inverted row,
    single arm row, shrug, RDL, deadlift, and sumo deadlift.
    In a T-bar row, you utilize a detailed, impartial grip
    together with your elbows tucked in close to your torso.

    Research show that the inverted row works many of the back muscular tissues simply as nicely as the barbell row, but with less load on the backbone.

    chest-supported T-bar row is a wonderful different. The obliques particularly are working isometrically to withstand rotation, making the single-arm dumbbell row much like the Pallof
    Press within the sense that it’s an anti-rotational train. The barbell row,
    like the barbell squat, deadlift and bench press, is commonly touted as a key compound motion, important for building muscle.

    burden again up, after which bring the burden all the way in which down. So,
    in addition to working your upper back, scapular
    wall slides additionally present your chest with a
    useful stretch. As its name implies, this muscle is positioned on the again of your shoulder.
    The rear delt is usually underdeveloped and desires
    loads of direct coaching to guarantee that it doesn’t lag behind the
    other two deltoids. This additionally is dependent upon your health objectives however, as a basic rule,
    sure you could.
