Viete, čo znamená...

... čas pre ľudstvo na našej Zemi, a čo keby sme sa pozreli za hranice našej planéty a „posvietili si“ na slnečnú sústavu? Zistíme aké rozdiely v ponímaní nášho času na nich panujú.

Hviezdy patria medzi najpočetnejšie a najľahšie pozorovateľné vesmírne objekty aj bez optických prístrojov. Väčšinu ostatných telies vo vesmíre vidíme len preto, lebo odrážajú svetlo hviezd (napr. planéty). V slnečnej sústave poznáme osem planét. Sú to Merkúr, Venuša, Zem, Mars, Jupiter, Saturn, Urán a Neptún. Môžu mať vlastné prirodzené obežnice. Pokiaľ ide o väčšie telesá (rádovo minimálne kilometrových rozdielov), nazývajú sa mesiace.

Čas je abstraktný pojem, ktorý si ťažko dokážeme predstaviť. Storočiami bol doménou filozofov a prírodovedcov, ktorí sa ho snažili zadefinovať. Dôležitým pojmom je tzv. šípka času, ktorá určuje smer plynutia času a odpovedá smeru rozpínania vesmíru. Od staroveku sa meria najčastejšie počítaním pravidelne sa opakujúcich pohybov, napríklad Slnka alebo kyvadla. Naša Zem sa okolo vlastnej osi otočí za 23 hodín a 56 minút a 4,1 sekundy.
Vedeli ste, že ak by ste sa postavili na jeden z pólov, nevideli by ste východ Slnka až 179 dní?

MERKÚR
- Jeho rotácia okolo Slnka je rýchlejšia než rotácia okolo vlastnej osi.
- Jeden slnečný deň na ňom trvá 176 pozemských dní, čiže dlhšie než dva merkurovské roky.
- Teplota na povrchu sa v noci a počas dňa líši o celých 600°C. V noci padá na -180°C a cez deň sa vyšplhá až na 430°C.

VENUŠA
- Patrí medzi najpomalšie telesá slnečnej sústavy. Zem okolo svojej osi uháňa rýchlosťou 1670 km/h, Venuša len 6,5 km/h.
- Jeden deň na Venuši trvá približne 243 pozemských dní.
- Zem okolo svojej osi uháňa rýchlosťou 1670 km/h, Venuša len 6,6 km/h. Okolo Slnka sa otočí za 224 dní, čo znamená, že tu je dlhší deň než rok.
- Celá planéta je vystavená skleníkovému efektu, ktorý jej povrch rozpáli na 500°C.

MARS
- Na Marse je všetko skoro dvakrát dlhšie ako na Zemi. Deň tu trvá 24,5 hodín a rok trvá 686 dní. Ročné obdobia sú tiež dvakrát dlhšie a priemerná teplota na povrchu je – 56°C. Vietor však dosahuje rýchlosť až 400 m/h.

JUPITER
- Deň tu trvá len 10 hodín. Krátky deň je vyvážený extrémne dlhým rokom 4335 dní. Narodeniny by ste mu mohli oslavovať každých dvanásť rokov...
- Je to veľmi nehostinná planéta bohatá na obrovské búrky v atmosfére, ktorá je zložená z vodíka a hélia.

SATURN
- Veľmi podobné podmienky nájdete aj na Saturne.
- Deň tu trvá 10,5 hodín a rok až 10759 dní. Deň tu trvá 29 pozemských rokov.
- Teploty v hornej oblačnej vrstve atmosféry dosahuje -140°C, ale o 500 km nižšie sa obrovské vodíkové oceány.

URÁN
- Atmosféra tejto planéty patrí medzi najchladnejšie v slnečnej sústave.
- Rok tu trvá 84 pozemských rokov, deň má 17 hodín a rok 30708 dní.

NEPTÚN
- Zaujímavosťou tejto planétky je, že dĺžka dňa na Neptúne závisí na tom, kde sa zrovna nachádzate na planéte. Je to z dôvodu, že póly sa otáčajú výrazne rýchlejšie a deň tam trvá 14 hodín, na pomalšom rovníku 18 hodín.
- Rok na Neptúne má 165 pozemských rokov.
- Poveternostné podmienky sú tam veľmi ťažké, rýchlosť vetra dosahuje až 1000 km/h a panuje tam mráz viac než - 200°C.

    In order to take benefit of your shoulder exercise and successfully train your delts,
    you should give attention to a couple of completely different variables.
    When you’re looking to strictly develop the middle delt you need the traps
    out of it. However when you’re trying to coach for energy and
    explosiveness, you want the entice to help as a result of it’s making an attempt
    to help.
    Your entrance delts comprise a important portion of your shoulder muscular tissues and are on the forefront if you deliver your arms ahead to hug somebody or
    bench press a heavy weight. Even if handstands aren’t your primary aim, the
    exercises are, after all, efficient for building shoulder muscle and strength.
    Plus, handstands are an excellent exercise for growing your bodyweight shoulder energy, taking your shoulders to the subsequent stage.
    You’ve now received an arsenal of 13 efficient workout routines to hit the traps from
    every angle with simply dumbbells. Make the most of this knowledge by creating your
    personal workouts, consisting of two to 3 workouts and ten sets.

    Read on to learn to do each train with professional suggestions, sets, reps, and the precise muscular tissues labored with every exercise.
    Push presses are exceptionally effective for building explosive
    energy and useful power and for improving athletic
    performance. Overhead presses are available in many shapes and varieties, but they're all among the many best entrance delt workouts.
    An incline of round 30 levels is perfect for successfully participating both the higher pecs and the front
    deltoids. Inside that range, you get an excellent balance
    of upper chest and front delt improvement without overly prioritizing one over
    the other. Your pecs are primarily a set of broad muscle tissue that cowl the higher
    area of your chest. They span out of your clavicle and sternum and reach their method across your chest and
    fasten once more to your rips.
    I clear the burden up to my shoulder, and now I’m attempting
    to press up overhead explosively. I’m allowing the legs, the hips and my complete physique to help me on this motion. Simply like I would if I was out
    within the field of competitors and I needed to push somebody away from me.

    If you care about your posture, shoulder health, or joint
    stability, this exercise wants a spot in your workouts.
    Do it between sets of horizontal presses to keep
    your shoulders balanced and robust. Lateral raises are one
    of many few isolation shoulder exercises that target the lateral (medial) delts.
    Working the edges or 'caps' of the shoulders, lateral raises may help build the enduring V-shape prime half.
    They are a great train to incorporate within the second half of your shoulder exercise following your compound lifts to focus on building
    measurement in the lateral delts. Most trainees use barbell
    upright rows with a narrow grip to assist develop the mid-traps.

    A single-arm dumbbell row is one of the greatest dumbbell shoulder exercises because
    of what number of muscle tissue it hits. You can develop the
    rear shoulder, lats, and higher back muscular tissues with a single arm row, making it a fantastic option if you're brief on time.

    If you prepare your posterior deltoids with your shoulders, reverse dumbbell flyes are the ideal isolation movement.

    Nonetheless, rear delts fit simply as properly on again day, so feel free to do them then as a substitute.
    The barbell overhead press, sometimes generally known as the navy press, is a staple in shoulder exercises for newbies, bodybuilders, and
    superior athletes alike.
    Deadlifts are considered the king of back workouts as
    a result of their capability to interact multiple muscle groups, together with the decrease again,
    lats, traps, glutes, and hamstrings. Emma loves building her
    own functional strength and fitness outdoors of work with varied coaching kinds,
    from weightlifting to calisthenics, yoga, and dancing.
    She advocates for the highly effective potential of exercise to improve physical, psychological, and emotional health and
    well-being. Each of the three deltoids heads benefits from a variety of rep ranges.


    In athletes, it often comes in the type of overuse accidents or improper mechanics.
    The level is that in order to perform daily and lifting tasks optimally, your
    arm needs a steady base. So, right here is the complete Perfect Shoulder Exercise step-by-step, all sets, all reps so that you just
    can comply with.
    You can do this exercise utilizing one arm at
    a time, allowing you to change the range of movement by adjusting the
    beginning or end position. The dumbbell push press uses a lower-body dip, suppose
    quarter squat to push the dumbbells overhead.
    Push presses use the triple extension of the ankles, knees, and hips,
    which closely mimics what occurs on the sporting area.

    Let’s dive into a quick and easy-to-understand anatomy walkthrough.
    Some individuals are blessed with extensive bone constructions giving them broad shoulders with no training.

    If your rears are in arrears, simply comply with this routine
    for 4-8 weeks—or alternate with a extra balanced shoulder routine—to help bring them up.
    Row the weights with your elbows pointing outward till
    your upper back is fully contracted. Hold the place as you faucet one shoulder at a time with
    the alternative hand. Stand next to a wall or different sturdy floor
    that may support your physique weight. Bend your elbow ninety degrees, and draw
    your shoulders again and downward.
    Keep In Mind, consistency is key, so keep difficult those muscular tissues and watch your delts grow.
    If you keep it up, you'll have to turn sideways to walk by way of doorways in no
    time! So, grab these weights, hit the fitness center,
    and let your delts do the talking. Immediately, I thought I needed to move round
    super heavy dumbbells to see any outcomes on my side delts.

    If a triceps dips bar isn't available, utilize a bench or chair
    as a substitute. On the other hand, isolation actions, like biceps curls, skull crushers, and lateral cable raises, target one muscle group at a time, specifically for muscle hypertrophy targets.
    A nice way to measure progressive overload is by setting percentages of load for every week of your program relative to your one repetition of most effort.
    One rep max efforts are the most relevant
    with compound movements but are simply as helpful with isolation workouts (can use 5 rep max instead).
    Doing dumbbell shoulder workouts daily just isn't recommended.
    The side-lying rear delt fly is an higher again train used
    to focus on the rear delts and rhomboids.
    The reason why it is so efficient at growing massive boulder shoulders
    is as a result of the cable machine offers you with constant resistance, one thing which most free weights just
    do not do. If you're looking to goal the rear of your shoulders, and your posterior deltoids, then doing dumbbell
    reverse flys, or particularly, bent-over dumbbell reverse flys,
    is the greatest way to go. The plate entrance increase is a novel and simple but effective train for building power and muscle in the entrance of your shoulder.
    Nevertheless, if you have healthy shoulders, you
    possibly can safely carry out this great exercise
    by not elevating your higher arms above shoulder top on the top of the motion.
    Dips are a compound train that primarily targets the triceps, but
    also works the chest and shoulders. Even though your muscles may be strong sufficient to raise the
    load, the joints and tendons aren't strong enough to
    assist the higher stress. The one draw back of this train is that it can place heavy stress on the shoulder
    joint, especially for those with a shoulder harm
    or restricted mobility. Also, choose a weight that lets you get reps
    on the primary set (to failure). You most likely will not be succesful of hit reps
    on subsequent units due to the continuous back-and-forth nature of the sets,
    which minimizes rest.
    You May be hitting them from all angles with a shotgun-style
    unfold of reps and sets. So remember to warm-up totally, then work your way
    by way of 5 rounds of the following circuit.
    Purpose to keep your form tight throughout, selecting your weights accordingly, particularly on the excessive
    rep units. Earlier Than you start lifting heavy along with
    your shoulders, you must make certain they're correctly warmed up.
    That Is the place this sequence from fitness director Ebenezer Samuel, C.S.C.S.

    comes in. Right Here, you'll focus on exterior rotation at the shoulder joint, a movement that completely offsets
    the greatest way that everyday life forces you
    into inside rotation.
    Begin in a daily shoulder press place, however as an alternative of pressing straight upwards, press up and away
    at about a forty five diploma angle. 'This is super helpful should
    you're limited to gentle wights as you'll have the ability to nonetheless get that
    stimulus on your delts,' says Tracey. Grab a pair of dumbbells and let them hold at
    arm’s length next to your sides. Hold a dumbbell in both hand
    and stand together with your legs broad, knees slightly bent.

    Swing each dumbbells to one aspect and carry them up as if
    drawing a circle from hip degree to above shoulder peak.
    Swing the weights to the other side, dipping all the method down to your hip before
    elevating them again. This bodybuilder staple targets your
    shoulders, but also works your whole physique.

    Utilizing a controllable weight and specializing in the muscle-mind connection is much better than throwing round heavy weights
    utilizing momentum. After doing this train for a prolonged
    period, feel free to change out the barbell for dumbbells, Smith Machine, or a shoulder
    press machine. Sadly, there isn't a single train that hits
    all three heads of the deltoid with comparative intensity, so you want
    completely different workouts. The excellent news
    is that you just solely want these three exercises to construct the broadest, roundest shoulders of your life.


    While the entrance and medial deltoids are activated with "push" actions
    just like the bench press, dips, or ought to press, the rear deltoids are activated with "pull" movements.
    Due to this, you will probably train the rear deltoids on a unique day from the entrance and side deltoids.
    While the entrance and lateral delts are primarily involved with "push"
    movements, the rear delts are involved with "pull" actions.
    This difference is why the rear deltoids are often skilled on a different day than the shoulders, usually with
    a again routine.
    Maximize your progress through the use of a spread of training tools
    and strategies. For example, you can do entrance, side, and rear
    delt raises utilizing dumbbells, cables, suspension trainers (TRX), and resistance bands.
    Each one impacts your muscle tissue barely in one other way,
    and that variety is excellent for muscle growth. Some trainers consider that one exercise
    technique is best than the others, and that’s not true.
    I noticed actual progress once I took my shoulder workouts to the limit.

    Entice workout routines can go far beyond basic
    shrugs and be done with a set of dumbbells, and that's what we'll cover right now.
    The rear deltoid muscle tissue are usually essentially the most uncared for and but, they're arguably crucial for
    making certain correct posture. They also assist to
    avoid muscle imbalances and lower your risk of shoulder injuries.
    Right Here are my favorite shoulder day workout routines, targeting all three heads of the deltoids.
    By focusing on your delt muscular tissues, you can see enhancements in workout routines like Overhead Presses, Weighted Pull-Ups, and Lat Pulldowns on the cable
    pulley machine. The main operate of the lateral delts
    is to perform shoulder abduction – that's, lifting your arms out to your sides.

    Pair it with a non-stim pre-workout loaded with pump-friendly NO-boosting ingredients and
    go to town. Novices don't want to get fancy or high-volume
    with shoulder training—especially in the event that they're already hitting
    their entrance delts with any vital amount of chest training.
    Hit these three moves onerous, nudge the weights up over time, and they can be enough to grow on. Like the name hints, the
    dumbbell lateral raise works your lateral deltoids.
    In addition to the capabilities above, the different deltoid heads help in rotating your upper
    arm, and supporting your shoulder joint when you're carrying issues.
    If you want to construct sturdy, muscular shoulders, incorporating the right shoulder exercises
    into your workout routine is crucial.
    Hold your elbows near your physique as you push again up explosively.
    Bent-over rows develop back thickness and strength,
    particularly in the lats, traps, and rhomboids.

    They also improve pulling power for actions like pull-ups
    and deadlifts. Here are 4 exercises that cover these bases and
    may be accomplished as a stand-alone routine two to a few instances per
    week or integrated into your regular exercises.
    These imbalances are common in people who spend long hours sitting at a desk, hunching over gadgets, or repeatedly performing overhead motions in sports activities or exercises.
    Reasonable intensity (10-20 reps on your first set if taken to
    failure) might have the best tradeoff between stimulus and fatigue, so goal to do 50% of your weekly volume on this
    range.
