Keď testosterón škodí

Vypadávanie vlasov postihuje stále väčšie množstvo mužov a žien. U žien v mladšom veku je príčinou vypadávania vlasov obvykle nevhodná starostlivosť či zlá životospráva. Vlasy môžu ženám prechodne viac vypadávať i po pôrode, čo súvisí s hormonálnymi zmenami počas tohoto obdobia. 

par dropovic femmeVo vyššom veku je príčinou vypadávania vlasov menopauza. Strata vlasov je v tomto prípade trvalá. U mužov je príčinou vypadávania vlasov mužský pohlavný hormón testosterón. Testosterón, ktorý inak robí mužov mužmi, má tak aj svoju odvrátenú stránku. Pôsobením testosterónu sa vlasové cibuľky postupne miniaturizujú, vlas sa stenčuje až nakoniec vlasová cibuľka odumiera. Tento nepriaznivý účinok testosterónu sa u niektorých mužov prejavuje už vo veku okolo 20 rokov. 

 „Najlepší spôsob ako premýšľať o raste vlasov je predstaviť si záhradu. To, ako rastú jej jednotlivé rastliny, závisí od toho, čo sa deje pod zemou,“ hovorí odborník na transplantáciu vlasov, doktor Ján Popovič z Dr. Popovič Inštitútu. 

Žiaden vlas nemá neobmedzenú životnosť – každý raz vypadne. Rastový cyklus sa obvykle pohybuje v rozmedzí 4 - 6 rokov. 

„Cyklus rastu vlasov ovplyvňujú niektoré lieky, chemické látky, choroby a infekcie, stres, trauma a pod. Vlasy môžu vypadávať i po častom česaní či necitlivom používaní farieb a iných preparátov na vlasy založených na chémii. Po odstránení príčiny sa cyklus rastu vlasov obvykle upraví,“ dodáva MUDr. Popovič.

Alopécia

Alopécia predstavuje ochorenie,  ktorého určujúcim symptómom je strata vlasov. Strata vlasov môže byť difúzna alebo ohraničená a to v závislosti od príčiny. Postihuje mužov aj ženy. Najznámejšou je pravdepodobne androgénna alopécia, ktorej sa ľudovo hovorí mužská „plešatosť“. Je difúzna a mužov nie zriedka postihuje už v mladom veku – okolo 20 rokov. 

Pri podozrení na alopéciu je potrebné určiť, či ide o infekciu alebo je príčinou autoimunitné ochorenie. Diagnózu však môže stopercentne určiť iba lekár. Kým v prípade infekcie vlasy niekedy dorastú sami, v druhom prípade je strata nezvratná. Dá sa však riešiť  - jedinou účinnou metódou v tomto prípade je transplantáciou vlasov, kedy sa odumreté vlasové cibuľky nahradia živými cibuľkami, schopnými produkovať vlasy.

Keď sú na vine hormóny

Všetkých nás ovplyvňujú hormóny. Pri vypadávaní vlasov sa u mužov i žien uplatňuje testosterón (v žien ide o relatívne zvýšenie jeho hladiny v dôsledku poklesu ženských pohlavných hormónov). Mnohí muži s problémom trvalého vypadávania vlasov zápasia už v pomerne mladom veku. Ako hovorí odborník, príčina nie je vo výške jeho hladiny v krvi, ale v miere citlivosti vlasových folikulov (korienkov) na vplyv tohto hormónu, resp. jeho derivátu (dihydrotestosterónu – DHT). Vlasová cibuľka sa postupne zmenšuje, vlasy sa stenčujú, cyklus rastu sa skracuje až napokon cibuľka odumiera.

„Muži s vysokou mierou citlivosti na DHT začínajú plešatieť už okolo 20. roku života a táto časová hranica sa neustále posúva dopredu. Muži s nízkou alebo minimálnou mierou citlivosti na testosterón plešatejú len nepatrne alebo vôbec,“ hovorí MUDr. Popovič.

Vypadávanie vlasov u mužov popisuje tzv. Norvoodova schéma. Podľa nej ako prvé začnú vypadávať vlasy na spánkoch (kúty). Horná hranica čela sa posúva dozadu, neskôr začnú vlasy rednúť i v záhlavnej časti a napokon obe plochy splývajú. 

„Vypadávanie vlasov v zmienených predilekčných miestach hlavy je spôsobené faktom, že zatiaľ čo zadnú časť hlavy pokrýva koža, obsahujúca vlasové cibuľky, odolné na testosterón, horná a predná časť hlavy je pokrytá kožou, ktorej vlasové cibuľky sú na testosterón citlivé,“ vysvetľuje odborník na transplantáciu vlasov.

Jediným účinným a trvalým riešením straty vlasov je transplantácia. Vlasových folikulov, vhodná aj pre mužov aj pre ženy. Navyše, zákrok takmer nijako neovplyvní váš bežný život. „Technika transplantácie vlasových folikulov, ktorá sa označuje ako FUE (Follicular Unit Extraction), je nebolestivá, nakoľko sa vykonáva v lokálnej anestéze. Rekonvalescencia je krátka, pacient sa rýchlo vracia do bežného života,“ dodáva MUDr, Popovič.

    fade, and I’ve put this belt via plenty of abuse in the time

    of me. I was too worried concerning the belt coming on to focus on a proper squat.
    You must also reveal strong technique earlier than using coaching aids, like a belt, to extend your numbers.

    To make sure your squat is as a lot as par, you probably can brush up in your technique by reading my

    Total, it is a beautiful-looking belt with a classic leather aesthetic.
    Ultimately, this belt is very similar to the Gymreapers
    Quick-Locking Belt. It’s marginally costlier and doesn’t have patterned designs,
    but it’s a tried and true belt with great customer feedback.
    The Element 26 Belt is obtainable in a number of colours however no patterns, which I like
    about the Gymreapers and 2POOD belts. If you have an even bigger price range,
    Belt Fed Energy, Pioneer, Inzer, and SBD are other choices.

    Looking for a belt shop close by should take time
    and careful thought on all of your prospects. Whether
    your search is for an informal fashion belt or a weightlifting
    belt shut by, several neighborhood institutions carry premium items and
    skilled recommendation. Buying a weightlifting belt
    shut by has varied totally different benefits than ordering on-line.

    Because of its unparalleled support, lifetime, and adjustability,
    the double prong belt continues to be a favourite amongst powerlifters even when more modern versions
    are rising in popularity.

    again for optimum backbone relief, and thin across the hips and abdomen for comfy put on. This
    provides a unprecedented stage of custom-made comfort and stability.

    This belt is well-reviewed and obtainable at an excellent value with free transport.
    The Iron Bull Powerlifting Belt is a 10mm leather-based
    belt with a double-prong enclosure. I think lever belts are the best powerlifting decide,
    and the Gymreapers Lever Belt offers awesome bang for the buck.
    The Gymreapers Lever Belt is an reasonably priced IPF-approved
    leather powerlifting belt. The velcro enclosure is typical for this sort of belt
    and is easy to make use of.

    Dumbbell rear delt rows target the center fibers of the trapezius and the rhomboids.
    These muscles work collectively to draw your shoulder blades back and together,
    which is a motion known as retraction. Cable rows require using a V-bar, and they're performed from a seated position on a low
    pulley machine. As you pull the bar towards your gut, you bend your elbow and shoulder joints.
    Compound exercises corresponding to this lead to fast features in size
    and energy. Cable rows are an effective train for strengthening the again muscles, as properly as the biceps and
    shoulders. They can be utilized to focus on specific
    muscle groups or work multiple muscles at once.


    With this movement you turn the mechanics of the exercise into a unilateral context.
    Every rep must be accomplished at a gradual and thoroughly controlled tempo.

    If, because of injury or some other cause, any
    lifter must intense decrease back stimulus whilst also working the again itself, the Seated Cable Row is a
    great different. They are essential for stability and upper limb movement of
    the scapula and shoulder girdle. Be cautious
    when you have an present or past shoulder or decrease back injury.
    Seated rows also affect the serotonin ranges in your physique, which can help promote sleep.
    Serotonin seems linked with results on temper, urge
    for food, digestion, and reminiscence.
    The seated cable row primarily works out the
    muscular tissues within the back and biceps
    secondary. The seated row is a compound train that works the
    latissimus dorsi, rhomboids, trapezius, and biceps brachii muscular tissues.
    It is a beginner-friendly muscle movement for all weightlifters, from sports activities athletes to Strongmen and bodybuilders.

    And speaking of chasing numbers, there are a quantity of different frequent errors
    to avoid when making an attempt to carry out the seated cable row correctly.
    Squeeze your shoulder blades collectively and have interaction your lats
    as you reach the highest of the movement, touching
    the bar to your stomach. Your again should be
    straight all through and your torso shouldn’t be moving again at all.

    Particularly, they work the latissimus dorsi (lats), rhomboids, and trapezius muscles.

    Moreover, they also interact your biceps and forearms as stabilizers
    in the course of the motion. Cable rows are a great exercise for strengthening the again muscle tissue.

    Throughout a cable row train, these muscular tissues contract to drag the
    burden in course of your physique. When performing cable rows
    with proper type, you should feel your lats working as you pull the burden in path of you.
    To start, sit facing away from a cable machine with knees barely bent and toes flat on the bottom or elevated on a platform if
    out there. Grasp the deal with hooked up to the cable machine utilizing an overhand grip then lean forward barely while keeping your spine impartial before initiating the pulling motion towards chest stage.
    Squeeze your shoulder blades collectively on the high of motion then slowly return arms to beginning
    position earlier than repeating for desired variety of reps.
    The seated cable row is a seated compound
    rowing exercise involving a cable machine.


    The resistance should not be too troublesome the place you cannot
    totally pull the burden to your chest or require coming ahead to satisfy the handles.
    This, along with rounding the back, are the commonest kind mistakes seen. Not solely do
    these mistakes cheat the motion, however they might additionally lead to joint ache
    and muscle injury. For cable row, completely different deal
    with attachments are available, and the grip you utilize
    can goal completely different muscle tissue. You can strive these alternate options if you’re
    in search of a similar exercise to switch the cable row during your training periods.

    As A Substitute, hold an upright posture and use your core
    muscular tissues through the exercise. Protect
    your decrease again, get a more effective
    exercise, and really feel unstoppable.
    Slowly releasing the row engages the biceps, building power with a sluggish launch.

    Talk to your doctor or physical therapist earlier than attempting seated rows when you have a current or past again, shoulder,
    or arm injury. A private coach can show you safer alternate options to work the same muscular tissues.

    The seated row, like all exercises, requires proper kind
    and movement to be efficient and safe. Having a powerful upper body improves posture, protects your shoulders, and reduces your risk of harm.
    A cable row permits for a larger range of movement and can be easier on the
    decrease again, whereas a barbell row could be more challenging and involve extra muscular tissues.

    This move primarily entails hanging from a pull-up bar and creating "active shoulders," Logan explains.
    You’re shifting from hanging fully relaxed along with your armpits floating up
    in the direction of your ears to partaking your shoulders/scapula/rhomboids
    by pulling your shoulders again and down, he says.
    Your best bet is to see a physical therapist, who can test for rhomboid weakness and help you sort out it.
    Progressively increasing the weight over time
    ensures that your muscle tissue persistently adapt, develop, and acquire strength.

    The Bent Over Rotating Dumbbell Row is performed by
    bending on the waist and using a dumbbell in every hand.

    As you row the dumbbells up towards your chest,
    rotate your wrists outwards and then inwards. This helps to have interaction the muscle tissue in the back and shoulders
    more than a standard row. This train could be carried out with
    lighter weights for higher reps or heavier weights for lower reps relying on the individual’s goals.

    You’ll get an efficient workout with both grip, so you'll be able to select what feels finest for you.
    In truth, research has proven the barbell bent-over row to
    be a superior exercise for the overall back, and using cables will
    offer the same advantages. The machine high row is
    a pulling movement to coach the back so it'll clearly be skilled on a type
    of two days.
    The overwhelming majority of machines use arms
    which are unbiased of one another. This means that you can pull them
    collectively (bilateral) or one arm at a time (unilateral).

    This is a huge advantage as all applications should have a mixture of both
    types of actions for maximal results. Of course, some of these actions are higher for development if carried out in a decrease rep
    vary. That said, they are completely appropriate for maximizing pressure on the higher
    again and middle again. They are compound movements, so ought to
    be certainly one of your main lifts.
    Correct execution with a good core and controlled movements enhances muscle
    density and development. They primarily target the latissimus
    dorsi, the biggest muscle in your again, helping you achieve that impressive
    "V" shape. If you’re in search of a training program
    that covers every muscle within the body as well as
    the again, we’ve obtained you covered. Examine out our ATHLEAN-X programs to
    see which is the best fit for your objectives and fitness stage.

    If you can not transfer the load via a full range of movement, you must finish your set and take
    a look at once more with a lighter weight. The seated cable row is a again train that primarily targets the latissimus dorsi.
    It also trains the opposite upper back muscle tissue, such because the rhomboids,
    traps, and posterior deltoids.
    Sturdy latissimus dorsi muscular tissues contribute to stability
    in your shoulders. Shoulder accidents are prevalent in those who participate in sports activities that use overhead motions,
    similar to basketball, baseball, some track and subject sports, volleyball,
    tennis, lacrosse, and others. The variations
    and alternatives of the Seated Row include utilizing machines, altering the grip, moving
    the chest pads, and adjusting the positioning of your arms.
    Each set should use slow and clean, not jerky,
    movements to completely have interaction the biceps and back muscle tissue.

    Sitting on the floor permits you to simulate sitting on the machine.
    Hold your again straight and relaxed, together with your shoulders down and back.
    Doing it will make sure that you primarily work the muscle tissue in your arms and
    again.
    Slowly return to beginning place and repeat for desired number of repetitions.
    The main muscles worked are the latissimus dorsi,
    rhomboids, and trapezius. To carry out a row appropriately, begin by sitting or standing with your ft shoulder-width aside and your knees barely bent.
    Grasp the barbell or handle firmly with an overhand grip and pull
    it in the path of you while preserving your again straight
    and shoulders down. Squeeze your shoulder blades collectively
    as you attain the top of the motion to maximise activation of the targeted muscles.
    Rows are a good way to strengthen your higher physique and core muscular tissues, but have you learnt which ones?

    This move, beneficial by Gallucci, is one other great one
    to include in your energy warm-up. To be taught extra workouts that you ought to
    use in your coaching, go to our complete exercise library on the Match
    Father Project YouTube channel. Finishing the train properly will
    imply the best outcomes for you, while avoiding the potential of harm.
    In this tutorial and associated video, I Am Going To present you the correct technique of the exercise, so
    you can full it with confidence and safety. Make certain you
    retain your knees bent at this angle all through the
    set. Variations of the TRX row can be utilized to target completely different areas or add intensity to your workout.

    Then switch arms as you decrease yourself back
    down earlier than repeating on alternate sides again.
    This exercise is performed on the pec deck machine, however the motion is reversed.

    Reverse pec deck flyes require much less stabilization than other rear
    delt exercises as the action is guided by the machine. As such, you don’t have to worry about balancing the load or coordinating your actions.
    Because of this, most exercisers will have the power
    to use heavier weights which could be very helpful for muscle hypertrophy.
    Straightforward to do – the dumbbell rear delt row is easy to learn and master.
    It’s perfect for beginners but can also be suitable for more advanced exercisers.

    Weak rhomboid muscular tissues can even lead to muscle imbalances around the shoulder, Gallucci
    adds. "This imbalance could result in overuse of different muscular tissues, which might make shoulder and neck ache worse," he says.

    It normally consists of a padded chest assist, a seat, and handlebars or grips connected to a weight stack or plates.
    Many machines allow seated machine rows with an underhand, overhand,
    neutral, shut, or broad grip. Rounded decrease again – done seated or standing, there
    may be a tendency to spherical your decrease back during this exercise, particularly when you have tight
    hamstrings. A rounded decrease back is a weak lower again and prone to
    pain and injury. As such, you should do your finest to not round your again throughout
    dumbbell rear delt rows.
    This optimum place stabilizes your scapula, making certain correct muscle
    engagement and reducing the chance of shoulder accidents. By sustaining your
    wrists in this bent-back place, you’ll drive your lats to
    do extra of the work. To counter this, minimize the contribution of your biceps and forearms by adjusting
    your wrist position. One of the most important supporting muscles through the
    Seated Cable Row is the upper arm muscle tissue generally identified as the biceps.
    To experience shoulder extension, carry your arm backward in an upward arc.

    For shoulder exterior rotation, turn your arm outward, away from your torso.
    To locate it, find your armpit, move towards your backbone,
    and barely upward.
