Do you like the idea of tracking your swimming in real time? Would you like to see your swimming statistics during or after a workout or lesson? Well the newly designed AR googles (Augmented Reality) that have recently landed on the market will provide your stats during every workout and take your training to the next level.
 
Augmented reality swimming goggles have been designed to help swimmers track their swim times, distances completed and lap splits (to the hundredth of a second) during any swimming workout. This data will also help your coach and teacher to monitor your performance. These goggles can offer you and your Strictly Swimming London coach immediate feedback when in the pool and we can analyse your data during your lesson.
 
The sport of swimming has lacked behind other sports such as cycling and running in recent times (who have various gadgets at their disposal to monitor their stats for some time now). Whereas swimmers (during training and lessons) haven’t had gadgets to hand where they can use them in the water to record split times swum and monitor distances that have been achieved.
 
Such an invention is exciting for the sport of swimming which remains the number one participation sport in the UK with over 2.5 million people swimming in pools each week, according to figures from Sport England recently. This figure increases more if you include open water swimming.
 
There have been various smartwatches on the market for a while with limited functions. The Apple Watches Series 2 and beyond will calculate how many laps that you've swum or the stroke you've performed. Waterproof MP3 players and SwiMP3 players have provided underwater music. However, that’s really been about the level of functions available until now. These new goggle companies are claiming that they will revolutionize the way swimmers train.

Types of AR Swimming Goggles

The Form Goggles display metrics that you need to see in the moment which allow you to take control of your swimming during training and lessons. Developed in collaboration with top competitive swimmers, these goggles allow you to monitor split times, interval times, rest times, total time swum, stroke rate, stroke count, distance per stroke, pace per 100, pace per 50, distance, length count and calories burned (which is impressive).

The smart display is see through and is built right into the goggles lens, delivering metrics without obstructing your vision  https://www.formswim.com/
The FORM Swim Goggles intelligently detect turns and rest—and give you relevant metrics each step of the way. They even allow you to customise your display and review your stats via their App.
 
SwimAR is a holographic display for swimmers by attaching a lightweight, hydrodynamic and waterproof module to a regular pair of swimming goggles. This device includes an added extra GPS system for finding your way in open water.

This module can be attached to various goggle styles with flexible straps.

Overall Opinion

If you want to compare your personal bests through your swim training and lessons, then investing in some Augmented Reality goggles is definitely for you! These state-of-the-art swimming goggles will allow you to adjust your stroke to the pace you need, increase your stroke length if you are starting to shorten through your workout and also allow you to stop guessing your pace. For those swimmers with poor eyesight who cannot see the pace clock on the poolside, then these goggles will be ground-breaking. Using AR goggles seems to eliminate pausing to check your lap times during your workout.

The downfalls are that AR goggles are really meant for serious swimmers and secondly they seem not to be able to monitor kick sets at the moment (although we think the positives hugely out way the negatives).
Be careful if you are swimming competitively as these goggles are designed to be used during training but not at a swim meet as they are not FINA approved (yet)!
​
If you would like to use these goggles during your lesson with our London coaches, we will be able to analyse your stats and offer instant feedback on your split times and intensity performed during your swimming set.
The Strictly Swimming London team are excited to see these new AR goggles (even though they are pricey) and really believe that they will be massively motivational to swimmers all over the world.

There are so many brands of swimming goggles on the market nowadays, with a varying price range, but the best goggles are simply those that fit correctly and feel comfortable and stable on your face. You need to feel happy and confident that they will stay in place when swimming at your top speed.

Many of the Strictly Swimming London coaching team have a high-level competitive swimming background and all will tell you how they had a favourite pair of goggles or ‘lucky goggles’ they felt helped them when racing (many of these goggles being the lowest price). So despite the price of the goggles you are trying on, always opt for those that fit the best and make your feel confident that they won’t bug you during your lessons, workouts and races.
 
Getting the best fit with your swimming goggles

Try on a few pair of swimming goggles to find a fit that suits you best. For some, children’s goggles may fit better than adult goggles.  Hold the goggles to your face (without using the strap) and if you feel suction and they stay in place briefly, then they are most likely to be a good fit as you can feel a tight seal. If they fall off immediately, they won’t be a good fit and will hinder your swimming lessons and workouts.  The main areas to check out when trying on a new pair of goggles are:

Eye seal​ – After trying various pairs, opt for goggles that fit your eye socket size. With a good fitting pair of swimming goggles, you should feel even pressure around the eye sockets and seals the eyes well. Look at all eye socket types for men, women, all adults and even children’s goggles.

Straps - The straps are used to keep your goggles in place but not to provide the seal. The strap should not be tightened so much that it makes the goggle uncomfortable and creates marks around your eyes, because it is too tight. When wearing a goggle with two straps, place the lower strap about eye level at the back of your head and position the other strap a couple of inches higher. This provides a secure fit and will help to prevent your goggles leaking or falling off when you dive into the water.

Nose bridge – many goggles nowadays have an adjustable nose bridge to allow swimmers to personalise the fit and mould it to fit your face. Find a pair of goggles with a nose bridge that can be tightened or loosened to fit the with of your nose (without it affecting the placement of each goggle on your eye sockets).
 
Pool Swimming or Open Water Swimming?

If you are swimming in the sea or in open water, it is recommended that you opt for polarized swimming goggles. It is also important to find a pair of goggles which allow optimum peripheral vision when swimming in open water due to reduced visibility in unclear water.
A wide medium to large frame will maximize your field of view in the open water, allowing you to ‘sight’ better when swimming in rough water.
 
Swimming Goggles for Triathlon

Whether you are contending with the glare of the sun, murky water or cloudy skies, it is worth spending some time thinking about your needs before you buy some goggles for your triathlon swim leg.            
Adult triathletes who opt for a full open-water mask will experience greater drag than a pair of small racing goggles. That may be true, but a small pair of goggles wouldn’t stand up well to a kick in the face at the start of a triathlon. A full wrap-around goggle is a common choice for open-water swimmers and triathletes, and there are definite benefits associated with the greater peripheral vision and more even distribution of pressure around the eyes through long swims.

Goggles Keep Steaming Up

Goggles fog up because warm, wet air, usually created from your body heat, condenses on the cooler-than-air lenses. However, if your goggles feature an anti-fog coating and still steam up, it could be their age. In some cases, with regular usage, goggles can out-live their anti-fog coating, depending on the method used to apply it during manufacture. If yours are fogging up and are old or well-used, it might be time to consider investing in a new pair. Avoid rubbing the lenses or touching them during your lessons and workouts, as this will start to remove the coating.
 
Taking Care of Your Goggles

Goggle maintenance is not an exact science but by following our hints and tips you should prolong the life of your goggles. All you need to do is wash the chlorinated water off your goggles after your lesson in warm water, air dry them rather than wiping them with a towel and store them carefully to avoid scratching the lenses.
 
Happy Swimming!

No matter what swimming level you fall into, it is essential to find the correct swimming goggles for your lessons and training routines. It is essential in order to give you comfort and maximise visibility and quite simply prevent unwanted chlorinated water in your eyes.

There is nothing more distracting than an unsuitable and uncomfortable pair of goggles during your lessons. Finding the right fit can be a problem to many swimmers and can slow down progression during your lessons. For example, Strictly Swimming London coaches often experience clients struggling and being hesitant with their breathing technique simply due to wrongly fitted goggles. Water getting into clients’ eyes when swimming often hinders concentration during lessons. Wearing the perfect goggles during your lesson will ensure excellent vision, comfort and concentration.
Here is a simple guide to help you select a pair of swimming goggles depending on your needs.
 
Factors to consider when choosing goggles

Face shape – your swimming goggles should fit snugly on your face and eye sockets. This includes matching the width of your goggles with the width of your face. Some competitive swimmers wear smaller racing goggles or children’s goggles for a firm fit. Men and women have different contours of the face, hence why many brands sell both men’s and women’s swimming goggles.
 
Size and Shape – Goggles come in all shapes and sizes. They generally can be classified into small and large sockets, small and large frame size and small and large lenses. Large socket goggles don’t actually fit into your eye socket and rely on suction around the eye instead. Lens size is the size of the lens through which the swimmer sees. A larger lens allows the swimmer to see more with a wide-angle view during lessons. By contrast, small lenses are more streamlined but allow the swimmer a smaller field of vision.
 
Comfort – Select a pair that you can imagine wearing for hours a week without any discomfort. If you are swimming for reasonably long periods of time, comfort will be your main priority.  Swim training and fitness swimming will involve swimming many lengths in one session and you should therefore choose a goggle that feels comfortable around the eyes. Even a one-hour swimming lesson or a one and half hour Iron-man swim requires comfortable goggles.
 
Visibility - A flat lens will typically reduce your perception of depth and distance, whereas a curved lens increases peripheral vision in the water and provide a 180 degree range of vision. Some goggles even have slanted lenses to promote correct head position and body alignment. Visibility is essential in both the pool and open water and your choice of eye wear should provide this. Choose goggles with an anti-fog coating and UV protection. Coated lenses are better because you won’t need to defog them as often. 
Colour of the lens – Many swimmers tend to go for lighter coloured lenses for visibility, but if you regularly swim outdoors or in bright environments, dark lenses can be better in coping with the glare of the sun. 
 
Clear lenses are designed for indoor pool swimming with low light. Dark lenses such as mirrored lenses or smoky lenses are designed for sunny outdoor swimming to reduce brightness (just as your sunglasses work). Blue lenses are suited to both indoor and outdoor use and are designed to allow a moderate level of light into the eye but maintain protection from glare in bright conditions. Lilac lenses provide the best contrast for objects against a green or blue background.  Amber lenses are designed to filter the light to crisp up your view. 
 
Anti-Fog Lens – Regular untreated lenses tend to easily mist up when used in the swimming pool. Anti-Fog treated goggles on the inside surface of the lenses help to reduce fogging up while you are in the water. Many brands now come with anti-fog protection.
Avoid touching or wiping the inside of the lens as this can damage the anti-fog coating which cannot be repaired.

The most common shoulder injury in swimmers is subacromial impingement (known as ‘Swimmers Shoulder’). Such impingement occurs when the tendons of the rotator cuff catch and rub against the nearby humorous bone in the upper arm. The pain experienced during any swimming stroke is a direct product of this ‘catching’ and can be exacerbated as you perform hundred and hundreds of swimming strokes during your workout. Three out of the four strokes in swimming are predominantly powered by the upper body, and the shoulder works hard when we propel though the water.
 
Causes
Swimming puts the shoulder joint through a large range of movement. Even though such movement is relatively low impact as exercise goes, the sheer number of rotations of the shoulder joint has the potential to irritate the shoulder if the swimmer is not performing their stroke technique correctly. In fact, all Strictly Swimming London coaches will teach our clients the correct swimming technique with this in mind and create better swimming technique to avoid such issues. Please be aware that using a kick board or swimming hand paddles can further exacerbate ‘swimmer’s shoulder’.
Although classed as a ball and socket joint, the shoulder has a very shallow socket compared to the hip joint.  Even though a healthy shoulder of a swimmer should have no problems going through a full range of motion without any issues in the swimming stroke, the small size of the socket allows for this impingement and can lead to swimmer’s shoulder if recurring issues in the stroke are not corrected.
Shoulder impingement in the competitive swimmer is mostly caused by altered kinetics (movement and technique) due to muscle fatigue after hours and hours in the swimming pool. Strictly Swimming London coaches know this feeling only too well. Excessive training without adequate rest can cause swimmer’s shoulder.
 
Symptoms
Symptoms of subacromial impingement can be sudden or gradual and can be different from individual to individual. A decrease in some movement may be experienced but the shoulder will still be easy to move and won’t be stiff (like a frozen shoulder). Symptoms can include:

• Localised pain on the top of the shoulder (on the outer side)
• Pain that increases as you lift your arm
• Constant pain in the arm (dull rather than sharp pain)
• Pain may extend to the neck and/or down the arm in some cases
• Aching that gets worse at night affecting sleep
• Aching that gets worse whilst resting
• Weakness in the arm

 
Swimmer’s Shoulder Test
There is a very simple arc test to check if your shoulder pain is due to subacromial impingement. Stand with both arms by your side, then lift the arm out to the side all the way above your head. If you feel pain around 40 to 60 degrees after raising the arm to the side, and then for the pain to disappear at 120 degrees then you can bet its due to impingement. When performing this test, the palm of the hand must always face towards the body which means the shoulder has to rotate half way through this lift of the arm to keep the palm facing inwards at all times.
 
Contributing Problems in Freestyle Swimming Technique
Incorrect swimming mechanics are the leading factor in creating shoulder problems. Some freestyle technique problems leading to impingement include:

• A thumb first hand entry in freestyle or frontcrawl stroke which produces internal rotation of the shoulder and closes the socket
• Repetition of bad technique
• Inadequate (lack of) body roll in freestyle
• Swinging the arm behind the body (midline) during the arm recovery phase increases stress on the shoulder
• Pulling wide during the pull phase (outside the width of the body) whilst the body is rotating downwards
• Hand entry crossing the midline can stress the shoulders
• Overtraining is often associated with contributing to swimmer’s shoulder
• A sudden increase in the training load can bring on impingement
• Rounded shoulder posture in the freestyle swimming stroke can bring on impingement
• Timing issues in the freestyle stroke with delayed body roll to the arm stroke can further stress the shoulders
• A lack of warming up slowly in the pool and warming down contribute to shoulder injuries

 
Our Strictly Swimming London coaches will aim to identify the exact part of the stroke where the pain occurs and will work on making adjustments in your technique during lessons.
 
Diagnosis and Seeking Medical Advice
Seeking medical advice is important if you are experiencing shoulder pain in your swimming training or lessons after a few weeks.  If not treated appropriately, the rotator cuff tendons can start to thin and tear. X-rays and other imagining techniques may be needed to assess the changes in structure of the joint. The presence of ‘lazy elbow’ where the elbow on the affected side cannot be lifted to the normal height out of the water.
 
Preventing and Managing Swimmer’s Shoulder
There are numerous exercises you can search online for all of the following:

• Sleep on your back - take the pressure off your shoulder and keep your neck and shoulders in alignment.
• Application of ice packs may be recommended to reduce pain and inflammation
• Increase mobility in your upper spine (thoracic) – this will help in rotation and body roll, rotation to breathe, undulation in the butterfly stroke and help your dolphin kick.
• Improve scapular stability – strong scapular muscles in the shoulder can increase power and speed in the water and reduce the chance of injury.
• Strengthen your rotator cuffs – outside your swim training or lessons work with some stretch cords during your dryland training
• Perfect your swimming technique – apart from having fantastic technique and mechanics in the swimming pool, it is also vital to have good posture and body position to avoid shoulder injuries. Our London coaches are equipped to help you with this.
• Bilateral breathing when swimming freestyle can create symmetry on both the right arm and the left arm of the stroke.  It can also distribute stress on both right shoulder and left shoulder (and eliminate one shoulder taking the most impact and stress).

 
 
Treating Swimmer’s Shoulder

• Avoid movement and swimming strokes that are making the pain worse.
• Temporarily reduce training/lesson frequency and distances.
• Alter training routines so that different strokes are used more often throughout your lesson or workout. Alternating swim strokes will reduce this repetitive pattern and allow the muscles to function differently.
• Use swimming fins to enhance the propulsion from the legs and reduce the stress on the shoulder and upper body.
• Avoid the use of hand paddles and kickboards 
• If the pain does not subside, rest the shoulders and ask your physiotherapist when you can restart your swimming workouts.
• Poor swimming technique needs to be rectified and our Strictly Swimming London coaches will help you correct any issues and focus on the stress in your shoulders (and other injuries) whilst swimming any of the four strokes.
• Carry on with normal daily activities so that the shoulder doesn’t become weak or stiff.
• Take anti-inflammatory pain killers
• Have periods of rest to aid recovery
• Focus rehabilitation efforts on rotator cuff and scapular strengthening (numerous exercise can be found online)
• Follow your physiotherapists exercises to help improve posture, strengthen the shoulder and increase your range of movement.
• Steroid injections can help relieve pain if rest and exercises on their own don’t help.
• If all else fails, an operation called a subacromial decompression is available which involves widening the space and socket around the rotator cuff tendon so that it doesn’t rub or catch.

Summary

Competitive swimmers are estimated to take well over a million arm strokes in just one year, and this repetitive motion puts swimmers higher at risk of developing shoulder pain. With a high likelihood of injury if you swim many hours per month, it is important to be aware of the ways to prevent this injury from occurring and what to do if it does happen to you.  The easiest and possibly most effective treatment is rest.  Take time off from swimming to allow the inflammation to reduce before returning to the pool.  While resting, it is important to use ice to aid in decreasing inflammation of the tendons in the shoulder. And anti-inflammatory pain killers. You can also decrease the amount of overhead movements of the arm and stop any movement that brings on the pain. It is also vital to modify your stroke mechanics in the swimming pool to emphasize correct technique with each stroke to eliminate the element that is causing the pain. Our Strictly Swimming London coaches can show you all of the above in our private or group lessons and take a proper assessment of your problematic swimming stroke.
