The (NIH) National Eye Institute is reporting their study’s findings that myopia progression (nearsightedness) in children is slowed with the use of multifocal contact lenses. Myopia increases the risk of cataracts, glaucoma and retinal detachment later in life. Investigators of the Bifocal Lenses In Nearsighted Kids (BLINK) study published the results August 11 in the Journal of the American Medical Association,
Children wearing multifocal contact lenses had slower progression of their myopia, according to results from a clinical trial funded by the National Eye Institute, part of the National Institutes of Health. The findings support an option for controlling the condition, also called nearsightedness, which increases the risk of cataracts, glaucoma and retinal detachment later in life.
The Not-so-Good News
Myopia has surged in prevalence over the past five decades. In 1971, 25% of Americans were myopic, compared to 33% in 2004. By 2050, the worldwide prevalence of myopia is projected to be 54%, and the prevalence of high myopia, the most severe form, is projected to increase to 10%. High myopia means that a person’s vision requires at least -5.00 diopters, the unit of focusing power correction required to optimize distance vision.
Myopia occurs when a child’s developing eyes grow too long from front to back. Instead of focusing images on the retina — the light-sensitive tissue in the back of the eye — images of distant objects are focused at a point in front of the retina. People with myopia have good near vision but poor distance vision. Single vision prescription glasses and contact lenses are used to correct myopic vision but fail to treat the underlying problem.
The Really Good News
The good news is that children as young as 7 achieved optimal visual acuity and got used to wearing multifocal lenses much the way they would a single vision contact lens.
Shaped like a bullseye, the soft multifocal contact lenses have two basic portions for focusing light. The center portion of the lens corrects nearsightedness so that distance vision is clear, and it focuses light directly on the retina. The outer portion of the lens adds focusing power to bring the peripheral light rays into focus in front of the retina. Animal studies show that bringing light to focus in front of the retina cues the eye to slow growth. The higher the power added, the further in front of the retina it focuses peripheral light.
Multifocal Contact Lens Study
After three years, children in the high-add multifocal contact lens group had the slowest progression of their myopia. According to principal investigator, Donald O. Mutti, O.D., Ph.D., the E.F. Wildermuth Foundation professor of optometry at Ohio State,
There is a clear benefit from multifocal lenses at three years, but further study is needed to determine the ideal duration for wearing the lenses. Researchers will need determine how permanent the prevention of myopia progression will be once children stop wearing the multifocal lenses,” said Lisa A. Jones-Jordan, Ph.D., principal investigator of the Data Coordinating Center at the Ohio State University. A follow-up study is underway to see if the benefits hold among children in this study when they go off treatment.
“We also need more information about the exact nature of the visual signals that slow eye growth. If we understood that process better, perhaps we could maximize it to have an even stronger treatment effect,

That signifies that when we’re doing a compound pushing motion, we can’t fully have interaction the longer
heads of our triceps. So, if you’re trying to take your upper back to the next level, the barbell shrug is a must-add to your
workout routine. Read on to study more about this mass-building train, its benefits, and the muscular tissues
labored.
The key to utilizing special exercises is to start out with the basics and work in the course of the extra
superior variations over time. Too often, folks begin utilizing the Conjugate Method and imagine it’s a license to utilize as a lot exercise variation as
potential instantly. This usually leads to athletes
using special workout routines to play in the direction of
their strengths, resulting in ultra-specific adaptations biased
in the course of the particular chosen variation. The
Westside Barbell Conjugate Method offers many power and athletic growth training choices for a coach
or athlete.
Thanks to the narrower grip, there’s an elevated recruitment of
the triceps, which is why you’d wish to include it into your
workout. Different muscular tissues concerned embrace the shoulder muscle tissue (rotator cuff/front delts), which assist to stabilize the movement.
Equally, the close-grip dumbbell press can replace the close-grip barbell press.
A combination of non-compound movements, like tricep pullbacks and front arm raises,
can even replace this exercise. Compound movements are people who work
out several major muscular tissues (like the shoulders and chest)
without delay as a substitute of focusing on a single muscle (like the bicep).
A close-grip bench press is a compound exercise and a variation of the normal bench press.
This bench press grip is the traditional model and the one most carried out in gyms around the
globe. You Will have your arms at shoulder-width, or
just a bit wider. Powerlifters use it throughout competitions and
the relaxation of us use it to construct and strengthen the chest.
This variation works all three of the chest area equally (upper, middle, and lower).
The grip works more chest than anterior deltoid and triceps which makes it your go-to for extra general
chest size and power.
Leonard’s articles have been revealed in many high publications around the internet.
Leonard enjoys weight training, taking half in basketball and yoga, and likewise enjoys
climbing. Leonard Shemtob is President of Strong Dietary Supplements and a broadcast writer.
Leonard has been within the supplement house for over 20 years,
specializing in fitness dietary supplements and diet.
Leonard seems on many podcasts, written over one
hundred articles about supplements and has studied vitamin, supplementation and bodybuilding.
By perfecting your technique, attempting completely different variations, and fueling
your progress with focused dietary supplements, you’ll unlock new ranges
of strength and definition. Let’s discover how to carry out
it properly, its benefits, and how to combine it into your
routine for optimum results.
In order to construct all three heads of your triceps, you must in all probability add a triceps extension train. Some individuals will advocate
gripping the barbell even narrower than shoulder width, to the
point the place we can’t deliver the barbell all the best way all the way down to our
torsos anymore. That can be a good lift for emphasizing the triceps, however it’s not
what we’re talking about here. We’re talking about a bench
press variation that’s carried out with a close grip,
not a kind of triceps extension. Setting your bench to a 15 to
20-degree decline is a great way to spice up lower pec muscle activation. Most weight lifters find it easier to carry out decline presses as
they feel stronger when in this place.
If you’re not valuable about manufacturers, the Titan is an outstanding selection. The barbell might end
up decrease than usual due to the slim grip. Guarantee your posture feels natural and
pain-free when lowering the bar. They are simpler to
raise and put muscle tissue by way of an analogous vary of motion but don’t have interaction the forearms as
a lot. Workout Routines like narrow grip cable curls
definitely have their place as properly.
The conventional bench press and the extensive grip bench press both contain a greater range of
movement and can allow for extra muscle activation within the chest.
The close grip position may place extra emphasis on the triceps, however could
not fully interact the chest muscles. The extensive (overhand) grip barbell bench
press is a grip that’s 1.5-2X the width of your shoulders.
This variation maximally recruits the higher chest muscles
and reduces the vary of motion which decreases the amount of labor it takes
to lockout.
Be certain to add the Close-Grip Bench Press to your subsequent arm day and keep in mind you’ll find more “HOW TO” movies in the EXERCISE
section of the net site. Whether Or Not you choose the Barbell
Close-Grip Bench Press, the Close-Grip Dumbbell Bench Press, and even variations like
the Incline Close-Grip Bench Press, understanding and making use
of the best technique is paramount. The entire movement pattern of
the Close-Grip Bench Press, from the managed descent to the highly
effective push-up, should be easy and deliberate.
Chopping your motion quick not solely hampers muscle development
but can also foster dangerous habits that are hard
to interrupt. This retraction is crucial for stabilizing your shoulder
joints and offering a strong basis from which to press.
The shut grip bench press is a great exercise for building sturdy triceps and
bettering your bench press lockout. It also can assist to scale back elbow flaring and stress on the shoulders.
To do an in depth grip bench press, arrange a bench press with the bar
set at chest height. Place your hands shoulder-width aside,
or even nearer, on the bar. Decrease the bar to your chest, maintaining your elbows near your sides.
Mastering proper type in the shut grip bench press is essential not only for maximizing tricep activation but in addition for
preventing injuries and guaranteeing long-term progress.
This motion demands precision and management, because the narrower grip places increased stress on the triceps while requiring stabilization from the chest and shoulders.
Use it to focus on the higher chest, as it’s proven to energetic
the upper head of the pec main really well. So, it’s not going to be
your major chest exercise, however an assistant/accessory carry.
Conversely, in case you have hassle benching because of shoulder ache, then you could discover
the reverse grip is the easiest way to bench press (i.e.
if you cannot do normal or extensive grip, see
if reverse grip works!). As with any resistance train, you must use
a weight that you can lift safely however which additionally challenges you.
This is why in power athletes, it’s often used as an adjunct carry to supplement the development of the regular grip
bench press. The shut grip bench press, when in comparability with
wider grip bench presses, does not recruit as a lot shoulder energy to move the weight.
You could also be new to weightlifting or a
seasoned lifter wanting to improve your upper physique routine.
Including the close-grip bench press to your strength-training program is an effective way to build energy and
is definitely modified to every health stage. Yes, the close-grip bench
press emphasizes your triceps muscles more than the common bench press.
For bench pressers, which means the triceps—and to place even more emphasis on the tris, the close-grip bench press is the go-to train. Bodybuilders ought to think
about including close grip bench press due to the added stimulation to the triceps and the upper chest.
It is a compound raise that can be included as a main movement,
especially for these concerned with aesthetics over maximal strength, to be followed by extra tricep and chest
isolation work. Other higher chest workout routines often involve bodyweight and cable work.
If they’re not stacked, then there’s
a good likelihood you might be gripping too slim to get probably the most out of this exercise on your triceps.
Once you’ve hit your chest you’ll begin your concentric
or lifting portion of the train. For the press, think about preserving the elbows relatively tucked and sustaining that robust stacked position with the wrists and elbows.
Set and brace similar to how you’ll in your barbell bench press.
Make sure the ft round grounded, the hips are on the bench, and the upper
again is set and prepared.
Activating less chest and putting the load on the triceps means you’ll raise much less weight.
However if you’re looking to build triceps and enhance your lockout
power then this is good. Plus, because the shoulder is extra internally rotated and fewer externally rotated,
you’ll take the onus off your shoulder joint. And the shut grip
press has great carry over to the lockout portion of the overhead and
commonplace bench press.
Most lifters solely perform the wide-grip bench press,
failing to incorporate the close-grip press into their exercise routines.
That’s as a end result of they don’t understand the advantages of this significant train.
Otherwise, you’ll put undesirable stress in your triceps, elbows, and
joints. If done accurately, close-grip bench press is an efficient exercise to incorporate in your tricep
train routine.
While this exercise requires a premium subscription, StrengthLog is
100 percent free to download and use as a workout tracker and basic power training app.
Feel free to use an EZ curl bar (if you have one)
to reduce back wrist pressure compared to a straight barbell.
And sure, even the intermediate-level nine-set strategy is 10+
set for your triceps in actuality. This tricep exercise is suitable for
all health ranges, from newbies to advanced trainees.
This, in flip, makes for a variety of orthopedic advantages and a decrease in damage threat for the person working out.
For the purposes of this information, let’s conservatively assume that you have a slim 42-inch rack.
The good grip is only a theoretical time period and it
by no means occurs, which also goes for the perfectly balanced Swiss barbell.
We’ve gone over all the explanation why you should do it, however now we’re
at crucial half. Make certain you employ
correct type so you’re getting as much out of this train as potential.
Verify out our strength standards for Barbell Curl, Pendlay Row, Pull
Ups, and more. Focus on maintaining your elbows tucked in, it is easy to by chance let them rotate outwards.
Don’t simply drop the barbell – actively information it back down slowly.
The effectiveness of the Conjugate Methodology may be attributed to the system’s capacity to deal
with…
With a single bench press, you can kill two birds with one
stone by working on totally different grip kinds and training your energy and arms.
If you’ll use a narrow grip, your bench press wrist position is going to be totally different than regular.
Nonetheless, this definition is somewhat arbitrary, and beginners who
don’t have a consistent bench press grip might have a
difficult time determining where to actually place their palms on the bar.
Maintain a regular grip along with your thumb and fingers wrapped across the bar during the train. There is an increased risk of dropping the bar
and harm using a false grip (fingers and thumb on the identical side of the bar).
It depends on your anatomy and the aim behind why you’re doing the exercise.
You can mirror the consequences of reverse grip rows with just your physique weight for resistance.
This is a wonderful exercise for calisthenic athletes and anybody who prefers
bodyweight training over weight lifting. All three sets of fibers are involved in reverse grip rows, however the center fibers are essentially the most energetic as they work to tug your
shoulders again and collectively. The center traps work with the rhomboids, which are small muscular tissues situated between the shoulder blades.
Located on the perimeters of your higher back, the lats are the muscular tissues that give you your V-taper and torso
width.
When compared to the standard barbell and dumbbell bench presses, shut grip dumbbell presses do not put
that much strain on your shoulders and thus, can help
you expertise less shoulder ache. The incontrovertible truth that you’re
maintaining your higher arms close to your sides and don’t
use heavy weights reduces rigidity on your shoulders
and makes it easier to carry out the train. The first exercise within the barbell
tricep exercise is the close-grip bench press, a variation of the usual
bench press the place you place your palms closer collectively on the barbell.
The narrower grip emphasizes your triceps greater than the broader grip does.
However when you haven’t obtained time for that or you want to prolong your warm-up, ramp-up units are your greatest friend.
These sets assist grease the groove and assist you to determine your working weight
for the day, and the additional quantity is helpful for fat loss and hypertrophy.
For more lifts targeted on the chest, shoulders and
again try the Upper Body Lifts part of the Train Library.
In this guide, I will educate you how to correctly do Barbell Shrugs, explain what muscular
tissues they work and provide you with a number of variations.
The assist of the seat and pad reduces any strain on your decrease backbone and
likewise ensures optimum type, which means you’re much less likely
to injure your self or recruit different muscles to take
the load off of the biceps. To an extent, you’ll even be working your
shoulder and forearm muscles, although solely as stabilizing muscular tissues.
One Other advantage of the motion is that it teaches you to
press with out flaring your elbows. The skill is useful when using a wider
grip to target your chest as a result of it protects your shoulders
and improves your pressing energy. Begin by adding the
close-grip bench press to your exercises as a supplement to the
usual benching you already. As Soon As you’re more
confident with the motion and your grip, you presumably
can go even heavier and work in a 4 to six rep range to build
power.
Whether you are within the mood for a push up variation or tricep
extensions, we’re certain there’s an exercise here you’ll take
pleasure in. The bench press will be the money maker on your chest, triceps, and shoulders as a compound train and pushing movement.
But as we mentioned with the grip earlier, refined changes make
a big distinction, although it’s still just a bench press to the untrained eye.
Like any bench press, there might be some threat for shoulder pain,
however this position is safe for most in case you are
trying to build your pecs. You’ll discover this position permits
your elbows to travel slightly farther away from your body (but not
as far as a large grip) so you can get the deep
pec stretch on the bottom of the exercise.
Isolation workout routines, push ups, and dumbbell pressing exercises will serve you
nicely. You can proceed with the barbell bench press as properly, but use an applicable weight and construct
up the power. Whereas the close grip bench press is probably
certainly one of the greatest tricep workouts for loading the barbell
with heavy weights, it also works your chest and shoulders, making it a
great compound movement for all of the pushing muscle tissue.
