Full immersion terry laughlin. When will full immersion in virtual reality be created? Your main enemy

Reality, what we see, hear, touch, perceive with the help of our senses, is relative. It seems that this idea is already obvious for most of humanity. If we replace the signals sent to our brain by "feelings" with others generated in one way or another, we may not notice the substitution. We can only hope that the idea of ​​the film "The Matrix" has not yet found its technical embodiment. This, of course, is an exaggerated risk of virtual reality, but it should not be forgotten.

The term "virtual reality" is often used in relation to a variety of systems, to the extent that it is understood as the Internet. Naturally, such a loose use of terminology causes great confusion. To be more precise, the concept of "virtual reality" (VR) means a kind of artificial world, constructed using computer technology, into which a person can completely immerse himself not only as an observer, but also as a participant. VR systems are technical devices that create the illusion of being present in this artificial world and in some cases allow manipulating its objects.

The term "virtual reality" itself is far from new. Science fiction writers have long taken a liking to this topic and contributed a lot to its development. The worlds of Lem, Bradbury, the Strugatsky brothers appeared - why not virtual reality? True, only in the imagination of the reader. What does reality have to do with it? And you will remember how, after reading your favorite book, you did not notice how time flies, and if someone called you, it took a few seconds to return to reality. In other words, you were immersed in a fictional world. But for its visualization, the effect of presence is important.

By by and large, everything that we call a work of art is virtual reality in a broad sense. This is, first of all, a theater that has developed into modern interactive shows with a variety of stage effects, including laser ones. This is a fine art - even the Renaissance artists used the technique of direct glance, when it seemed to the observer that the painted portrait was following him with his eyes. Otherwise, as magic, in the Middle Ages, this effect could not be explained. With the advent of photography, a stereoscopic camera was invented (by the way, by our compatriot Ivan Alexandrovsky in 1854). Stereoscopes appeared, which became widespread in the middle of the last century - the prototype of modern virtual reality glasses.

The hall of the Stereokino cinema in Moscow, where the audience watched stereofilms using the glasses-free method. 1947 year

A new level of visualization was brought by the invention of cinema by the Lumiere brothers. Already the first commercial film show in the basement of the "Grand Café" on Boulevard des Capucines in Paris on December 28, 1895 caused a panic in the audience at the sight of an approaching steam locomotive... Then cinema became sound, color, widescreen and stereoscopic. In Soviet times, in Moscow and some large cities, in addition to the usual ones, there were cinemas with an extended effect of presence:

1. Stereoscopic. Cinema "Moskva" became the first commercial stereo cinema in the world, which used the glasses-free method of projection onto the screen, and the cinema "Oktyabr" had a stereoscopic hall with anaglyph glasses.

2. Panoramic. The Mir cinema is also in Moscow, where the projection was carried out from three cinema projectors simultaneously.


3. Circular cinema panorama at VDNKh. There the screens were located in a circle for all 360 degrees.


Nowadays we have 3D cinemas everywhere.

In 1962, Morton Heilig in the United States received a patent for a miracle of technology called a sensor.

He was a cinematographer with the goal of expanding the scope of cinema to the limit: to add taste, touch and smell to the image and sound. The sensor camera was, in fact, an analog simulator. By paying 25 cents and sitting on a movable seat, the viewer could watch one of five two-minute films. In addition to color widescreen stereo and stereo sound, such short films, which included, for example, demonstrations of riding a motorcycle in New York or flying in a helicopter, included the sensations of movement with vibration, turning the head and seat, using various scents, wind, blowing in the face. Nowadays there are 4D, 5D, even 7D attractions and cinemas with movable seats, hot and cold winds, splashes, smells and so on.

But everything mentioned above suffers from a significant drawback - the lack of interactivity. The viewer is passive, forced to follow the script and the maximum that can be done is to interrupt the session. In the 90s of the last century, the computer game King's Bounty was very popular. The player controlled one character (whose class was chosen from the four proposed) and could open the map in any direction, complete tasks, collect artifacts in an arbitrary sequence, that is, act independently. A virtual environment without freedom of choice in an artificial world is summarized by the concept of 3D. These are the main components of modern virtual reality: immersion (an interesting plot), the effect of presence (visualization) and interactivity (the freedom to choose the development of the plot).

Such opportunities are provided by VR systems: to get involved in the action yourself, and not only in a fantastic space, but also, as it were, in a completely real world, at least from the point of view of human perception. All this, apparently, predetermined the boom of new information technologies and, accordingly, their rapid development. In addition to the games and entertainment industry, virtual reality systems are increasingly infiltrating the business arena. They are widely used for practical applications, including surgical simulations, vehicle prototyping, equipment maintenance and installation, logistics operations optimization, business data visualization, military exercises, pilot training, and more. Replacing physical objects with digital models can significantly reduce time and money.

Simon Gauntlett (DTG) recently gave an overview presentation on virtual reality for the European Broadcast Union Workshop on Production Technologies. He considered it necessary to explain why the development of virtual reality will have to be taken seriously. As the first piece of evidence, he cites a wide range of cameras and glasses that have appeared over the past few months. The second piece of evidence is the opinion of analysts who estimate the virtual reality market at about 120 billion US dollars in the future until 2020. Mostly in the gaming industry, but who knows how game developers and broadcasters will interact further. The third argument was the growing number of companies and organizations involved in the virtual reality market. The main problems at the present time remain compatibility and the lack of an established terminology.

There are several main types of systems that provide the formation of virtual reality:

Modern virtual reality helmets are more glasses than a helmet, and contain one or more displays, and in the simplest case, instead of a display, a smartphone is inserted. The screens display images for the left and right eyes. In "advanced" helmets (goggles), a lens system is used to correct the geometry, as well as a tracking system that tracks the orientation of the device in space. The multichannel speaker system allows localization of the sound source, which helps the user navigate the virtual world using hearing. The helmet can be supplemented with interactive gloves and a suit, which have built-in sensors that transmit information about the user's movements to the computer.

As a rule, tracking systems for virtual reality are developed on the basis of gyroscopes, accelerometers and magnetometers. For systems of this type, the following are important: a wide viewing angle, the accuracy of tracking when tracking tilts and turns of the head, as well as a minimum delay between detecting a change in the position of the head in space and displaying the corresponding image on the displays.

Eye tracking systems monitor the movement of the pupils and at any given time can calculate exactly where a person is looking. When changing the position of the user's eyes relative to the displays, the image on them changes accordingly. Eye tracking systems determine the coordinates of the eyes in space. For this, various technologies are used: optical (determining the coordinates of the eyes in the image from the camera, tracking active or passive markers), much less often ultrasonic. These systems are actively implemented for marketing, military, scientific and other purposes.

The controlled character in the virtual world usually repeats these movements. There are two main approaches. First, a large number of sensors are attached to a person, and the computer monitors the movement of these sensors in space. The technology is widely used for shooting films where an actor plays a computer or comic character, for creating 3D games, etc. The main means of interaction with the outside world for people is their hands. Therefore, the idea of ​​creating a "virtual hand" has existed for a very long time. For this, it is proposed to use special gloves that track the movement of the hands and fingers. Another approach is based on pattern recognition. To put it simply, the person is filmed by a special video camera and determines what he did: waved or, for example, jumped.

Of various kinds simulators, the prototype of which was the same sensor, but with feedback. They are used to teach driving from a car to an airplane, as well as in various attractions such as a virtual roller coaster or an overturning house. In the simplest case, helmets / goggles with a movable seat and additional controls can be used. For virtual driving, an imitation of the cabin of a car / tank / plane, etc. is better suited. with displays instead of windows.

6. At the moment, the most advanced virtual reality systems are projection systems made in the layout virtual reality rooms (CAVE)... Such a system is a room, on all walls of which a stereo image is projected. The position of the user, turns of his head, the direction of his gaze are tracked by the above-described tracking systems, which makes it possible to achieve maximum effect immersion.

Virtual reality rooms (CAVE)

An output device that forms an image directly on the retina of the eye. The user places the device in front of him, the system detects the eye and projects a picture onto it using motion compensation techniques. As a result, you see the image "hanging" in the air. Devices of this type are closer to augmented reality systems, since virtual objects that the user sees are superimposed on objects in the real world. As such, a small VRD device could replace a full-size monitor. VRD, projecting an image into one eye, allows you to see simultaneously the computer and the real world, which can be used to create the illusion of "X-ray vision" - display internal parts devices and organs (when repairing a car, surgery). The VRD system, which projects the image onto both eyes, creates realistic 3D scenes. VRD supports dynamic refocusing for more high level realism than classic VR headsets.

Today mathematical models, software and graphic subsystems of virtual reality are sufficiently developed and available for mass use. Such technologies are firmly embedded in our lives in various forms. Progress in this area is moving fast enough. Does the abundance of promising technologies promise a brilliant future?

Let's go back to where we started and outline the risks of mass deployment of VR systems:

  • Physical - some people experience nausea, severe dizziness and even loss of consciousness.
  • Information security - for example, if users can change appearance their avatars, they can potentially impersonate other people.
  • Behavioral - for example, some game (and not only) situations can cause serious aggression of certain individuals.
  • Confidential - The virtual environment can dramatically increase the scope of potential privacy violations because every behavior can be tracked and every element can be changed.
  • Financial - spending a lot of money, you can get something completely different from what you hoped for.

So there is still work to do. An extended discussion and discussion of the problems of virtual reality, the development of terminology and the development of recommendations are expected in April this year at the NAB-Show 2016 in Las Vegas.

Hello friends! Today in the "Questions and Answers" section we will consider an interesting topic of full immersion in virtual reality. In this topic, there are several issues that interest people. Including the most important one - “ is there a full immersion virtual reality helmet". I suggest reading the information I know on the topic full immersion, in which I will also touch on other issues.

Before you head down below, I want to mention that many people screaming full immersion, while implying by this something completely different... The embryo of total immersion, if it becomes clearer. Perhaps you came here in search of this? Then I suggest reading an article about. It reflects many questions. If you are 100% sure that you are looking for information specifically about full immersion in virtual world then read on.

First, I propose to figure out what is generally meant by the phrase - full immersion in virtual reality... Full-immersion technology is a scientific invention of high-tech devices that feed computer-generated signals directly to the human brain.

At the same time, there is a kind of movement of the user of the technology of complete immersion into the virtual world. The virtual world, in this case, is usually a kind of game space, completely programmed on a computer and does not exist in our reality.

Usually, when you mention technologies of full immersion in the virtual world, it is customary to think about immersion games. Since the entertainment industry in modern world has priority. This can include games with full immersion in virtual reality and MMORPGs with full immersion and various reality shows for adults, where the player becomes a direct participant in the porn with full immersion.

Frame from the anime Sword Art Online

Summarizing the above, I repeat that the technology of full immersion in the virtual world involves deceiving all human senses, plunging him into a kind of dream-like state. Using the full immersion mode, the user is transported to a place that does not exist in reality.

At the same time, he realizes where he is and is able to completely control his nonexistent body there - an avatar, consciously performing certain actions. The user's body in the fictional world may not look like it. You can "put on" an avatar of a typical orc, goblin or elf - everything that will be programmed by the developers of the virtual world. Highly advanced immersion technology emulates gustatory and olfactory sensations and allows play in and instead of sleep. You've probably heard of lucid dreaming? Here's something similar, but much more advanced.

Is there a full immersion virtual reality headset?

The main question that worries many is whether there is a helmet, or rather,. And the answer will disappoint you - no, this full immersion headset does not currently exist on the market. So far, all the necessary concepts are only on paper and in the projects of scientific minds. Scientists of different years have long predicted that sooner or later a full immersion neurohelmet will appear. Few people know that a neuro headset for full immersion games is only the first step in the technology of full immersion, predicted by science fiction writers and having a real chance of becoming a reality.

Full Immersion Nerve Helmet from Sword Art Online Anime

Full immersion capsule in the virtual world is the next evolutionary step in the development of full immersion technology. If the (neuro) full immersion virtual reality helmet is worn on the head, then the player's body is completely placed in the virtual reality capsule. The difference here is that the virtual reality capsule has more power and is capable of affecting all human senses, which is not possible with a fully immersed neurodrive. The player's body is safe.

You can play in a full immersion capsule much longer than in a neuro-helmet, up to, sorry, automatic fulfillment of natural needs in a special container. Feeding can also be carried out automatically using nutrient mixtures. Adequate food is not a substitute, but it will allow you to live in the game for a day or two without any special consequences.

This is what a basic level full immersion capsule might look like.

You can get the best idea of ​​how these devices work by watching an anime about virtual reality or reading a genre called LitRPG. In the first case, I can recommend a very famous anime Sword Art Online, which demonstrates the operation of the neurodrive with full immersion.

What the industry offers today for a complete immersion in virtual reality

Almost everything that is today is either the rudiments of full immersion, or a kind of crutches. An example of the latter is a set of devices for virtual reality. One of the options looks like this: a controller for a helmet in the form of a weapon from the game and a special treadmill... In the video below, you can watch the operation of such a pair of devices.

The Virtuix Omni treadmill (the one in the video) is one of the first developments in this area, primitive but compact. There are also more advanced versions, which, however, due to their cost, are not very accessible to mere mortals. =)

The main problem of such ahem ... "total immersion", which is presented in the video, is the inability to fully control your body. You cannot jump, bounce, do a somersault. Many "intuitive" actions will have to be retrained, according to the technical capabilities of the track. Even looking from the side, you can see how uneasy and uncomfortable he runs. The weapon (controller) is one, while the game has a lot of them. Plus, swinging a sword on such a "path" will be very inconvenient and traumatic. What if a game about the world of sword and magic in virtual reality? How to manage to remove the sword to the side for casting a spell and where to look for it blindly?

However, I am too strict. Of course, such a realization of what already exists has its right to life. AND solves those problems that face the virtual reality industry right now- the problem of wires and the ability to move, albeit implemented so far at a basic level and with bugs. But, full immersion how some people position this approach, it is not even close. It's just pale shadow from shadow what awaits us when full immersion technology becomes available for purchase.

When the full immersion neurohelmet is invented.

Of course, we are all interested in a secret question - when they invent a neuro-helmet with full immersion... Well, when will the game with full immersion come out, which you can play, controlling the body as in life.

Unfortunately, today it is impossible to say for sure when full immersion virtual reality will appear. It is only in its infancy. There are virtual reality helmets that are able to clumsily try to deceive our organs of sight and sound. But don't be discouraged. Some science fiction writers predict the appearance of a virtual reality helmet with full immersion in 2022 - all in 5-6 years.

To date, there are several developments in the technology of full immersion in virtual reality. Most of them are classified and there is almost no information. But then there are already actually working prototypes of feedback devices. Already today, scientists have managed to build a device that allows electronic devices to be controlled using brain impulses. This means that the day is not far off when for the first time it will be possible to do the opposite, having constructed the world's first full immersion helmet.

How much will a full immersion VR headset cost?

Expensive. Very expensive. Even those that exist today cost about $ 600-800. At the same time, requiring a computer for 1000+ US dollars and a number of virtual reality accessories. In other words, even today the simplest virtual reality technology (with its best and most expensive version) costs the buyer almost $ 2,000.

Oculus Rift price at the time of pre-order

Imagine that in such neuro helmet for full immersion in the game equipment will be crammed several orders of magnitude more complicated and expensive. Let's talk about numbers closer to 10 thousand US dollars, least. Capsules in general thousand under 50-100 US dollars will cost. So, it's time to think about a pleasant old age in a full immersion game, where you will be young, handsome and playful again. We begin to accumulate slowly =)

Perhaps all the topics of full immersion were covered, if you still have any questions, you can always ask them in the comments... In turn, if there are any development news on the topic of virtual reality full immersion, I will definitely tell you about them on the blog pages. See you in the next article in the "Questions and Answers" section.

Full immersion. How to Swim Better, Faster and Easier Laughlin Terry

The Total Immersion Technique - a Revolution in Swimming Learning

The first edition of this book was released in 1996. In just a few months, without any advertising, it became a bestseller among books on swimming in the United States. Why? Because people began to achieve results, swim better and, naturally, get more pleasure from it. Many swimmers realized their mistakes and began to demonstrate steady progress.

Over the past six years, many readers have repeatedly expressed their gratitude to me. I take great pleasure in these letters as they show that I have achieved my goal of making good swimming technique available to everyone.

I confess that by following my method, I myself have reached a level comparable to nirvana. I enjoy every stroke. Maybe because I have never been a natural athlete, I came to the conclusion that everyone can learn to swim and this skill is by no means a special talent with which to be born.

The enthusiasm for the Total Immersion technique was shared with me by many swimmers. It doesn't matter how old you are, whether you can swim, a child or an adult, this technique will teach you how to swim better.

For several years it has become very popular. Everyone who met her, having read a book, attended a seminar, or simply watched a swimmer who applied our technique in practice in the pool, admitted that it made a revolution in their minds.

The Total Immersion (abbreviated PP) technique teaches you to swim like a fish. This approach can be described as meaningful swimming because it relies on a person's ability to analyze what is happening. Traditional methods of teaching swimming involve endless tedious exercises. In our view, this approach does not develop the skills needed to achieve long-term results.

We teach balance, improving the position of the swimmer's body in the water, sliding in it, which ultimately makes his movements rational and develops automatic skills.

Here are the main points of the methodology:

You will learn to swim like a fish. Instead of grueling workouts for a while, you will learn to glide through the water with the ease and grace of a fish. Your classes will become meaningful from the first swim.

You will master the technique of rational and harmonious movement. Your speed will definitely increase if you swim with ease.

You will change internally by learning gliding strokes. The PP technique can be compared to the spiritual practices of yoga or tai chi. You will improve spiritually and physically, improve your health and learn to overcome stress.

You will learn to swim through your creative journey. The PP methodology is based on the same principles of harmony and balance that are taught martial arts... You will start with simple skills and gradually develop them.

After the first lesson, your attitude towards swimming will change. Instead of just swimming along the path, you learn to swim and meditate at the same time, enjoying not only every movement, but also mental relaxation. If you swim with pleasure, and not from under the stick, you will gain favourite hobby for life. And if you want results in competitions, then, as practice has shown, sliding that gives joy can bring victory.

A tutorial on swimming according to the Total Immersion method.

We are publishing an extract from Terry Laughlin and John Delves' Total Immersion. How to swim better, faster and easier ”- about the Total Immersion swimming technique.

Total Immersion: Theory

Man is not made to swim. The body structure is not suitable for comfortable and efficient movement in the aquatic environment. Most techniques teach not so much how to swim, but how not to drown.

Ask yourself three questions:

1. Do you like swimming, does it bring you real pleasure?
2. Do you have a methodology that determines your training process?
3. Do you have an increase in results from using this technique?

Regular training using the Total Immersion method will allow you to answer “yes” to these 3 questions, learn to swim for a long time, easily and enjoy swimming!

For a professional swimmer, the following proportion is true: 70% of success is determined by technique, and only 30% by strength. For an amateur, the value of technology can be up to 90%.
Therefore, it is extremely important to work not only on the strength of the stroke, but also on the position of the body in the water. Correct position will help to increase the speed by 20-30%, and correct stroke- by only 5-10%.

Honored champion Matt Biondi and rising star Alexander Popov started in Barcelona in 1992 in the 50m freestyle. Popov won with a score of 21.8 seconds, Biondi came second with a score of 22 seconds. The time difference was small, but all the specialists were amazed by the number of strokes: Popov made 3 (!) Strokes less than his opponent in the 50-meter pool, which was a huge gap for athletes of this level. A new era in freestyle swimming has begun.

The speed is determined by the product of the frequency and the length of the stroke. The natural desire of an amateur athlete who wants to speed up is to start working with his hands more often and harder.

But video analysis of the champions' technique tells us that they take fewer strokes. Therefore, the key question is how to do longer strokes.

There are only two answers and options:
-power (to cling to the water with force, giving out maximum power with every movement of the arm and legs);
-sliding (the correct position in the water, which allows you to cover the maximum distance on each stroke).
1. The main enemy of an athlete in water is environmental resistance... And the only sure way to overcome it is the most streamlined and elongated body shape. Therefore, the most effective way is to work on the shape of the body, this is what allows you to significantly improve the results and spend less effort.

Note: better result can be achieved by working first at length, then at stroke rate. Finding the right balance between length and frequency is a fine tuning of technique to achieve a high result.

The main idea from a biomechanical perspective:
-What do you need to do to swim faster and spend less energy?
-It is necessary to change the position of the body in the water.

2. Speed ​​of movement in water
It seems to a swimming person that he is swimming at a constant speed. But this is not so, it is a sinusoid: the speed is maximum at the moment of the stroke with one hand and falls towards the beginning of the stroke with the other.

Usually everyone works to increase the maximum speed (at the moment of the stroke). But an effective approach is to increase the average speed, and this can be done by increasing the speed at a slow moment in the cycle.

The main enemy of the swimmer is the resistance of the aquatic environment. At what point is it smallest? At what moment is the area of ​​the body "resting" on the water wall minimal? At the moment of carrying bent arm forward. Body position: slightly on the side, one arm extended forward, the second in a bent, relaxed state after the stroke, goes from the hip forward above the water.

It is at this point in the cycle that it is possible to increase the speed by sliding.
Three basic rules of technique

Key rules of the "Full Immersion" technique:

1. Balance the body in the water.
2. Maximum elongated body.
3. Slide slightly on the side.

Body position

The main headache for beginner swimmers - the legs hang down, and the body, instead of a horizontal position, tends to a vertical one. It is usually assumed that you need to work harder with your feet. But this is not entirely true and not at all effective. By the way, big muscles legs take up most of your oxygen.

Terry Laughlin suggests imagining your body as a baby swing with a center point in the mid-belly area. And then use the float effect.
You've probably tried to submerge a ball sometime - and it certainly slipped out next to your hand. It is this property of water that must be used - you need to submerge upper part body, and the water will automatically raise the lower one to the surface.

Correct body position: close to horizontal.
Incorrect body position: legs are looking "at 20 (or 16) hours."

Maximum elongated body
Let us turn to the experience of shipbuilders: a vessel with a longer waterline is capable of moving at a higher speed. Thus, we need to lengthen our own body as much as possible in the water.

Theoretical calculations show that a swimmer 183 cm tall, covering a mile in 25 minutes, could improve his result by 7 (!) Minutes if he had a height of 270 cm.
Rule: when sliding, one hand should be in an extended position in front of the body.

How to sail:
-Every time before starting the stroke, try to reach an object that is far ahead (incorrectly pull your hand down to the bottom of the pool). At this point, your body should be as long as possible.
-Enjoy gliding. Do not rush to take another stroke, let your body slide.
- Feel the lightness of your hands. Both the straight hand and the hand carried over the water should be light.

Possible errors at this stage:
-Body balance is disturbed. The legs and pelvis pulls down and you try to push yourself out by lowering your hand.
-The head rises out of the water at the moment of inhalation. It also disturbs the balance and instinctively forces you to lean on the arm, which goes down.

Side slide

The most common mistake is to crawl on your chest (shoulders parallel to the bottom of the pool). The correct position of the body is on the side. This reduces the resistance. To swim 2 times faster, you need to apply 4 times more effort to overcome resistance. By reducing drag, we will spend less energy to increase speed.

Thus, with each movement you need to roll from one side to the other. And try to stay on your side for as long as possible in each segment of the cycle. Moreover, when the position on the side is combined with the movement of the front hand forward, the body acquires the most elongated shape. What we need to achieve maximum speed while sliding.

But swimming on your side is not very comfortable. We instinctively resist this position of the body in the water and roll over onto our chest. Therefore, at the first training in the "Full immersion" technique, it is important to consciously control every movement and position of the body in the water.

Total Immersion: Features of the training process

The principle of "eliminate and develop"

The first stage of learning to swim - it is necessary to take the most effective position in the water and eliminate the resistance of the aquatic environment. In the second stage, work out rhythmic and powerful pushing forward.

Do your hands work? No, the whole body works.
It is often believed that crawl should be done due to powerful muscles. shoulder girdle... But in fact, the impulse to move the body in the water does not begin in the shoulders, but in the hips! Because the main thing in swimming is not power, but rhythm, and the rhythm comes from the center of the body.

Notice how a tennis player is serving the ball or how a hockey player is hitting with a stick. They twist the body, and then seem to release the spring, putting the energy of the whole body into the movement. So why is it necessary to swim only with the strength of the arms ?! At correct technique and sliding on the side you connect the whole body, work gluteal muscles and large (deltoid) back muscles.

The impulse they generate is much more powerful than a single arm stroke. And at the same time, you will be much less tired, since the muscles of the arms will not be overstrained. You have to screw rhythmically into the water, the rhythm and rotation set by the hips.

What to do with your hands? Cling to water. You can imagine that you are climbing up an invisible staircase, trying to reach every next rung, clinging to it and pushing your body up.

Face the wall, lift it up as much as possible right hand... Bend your elbow and pull it up. There should be tension in the armpit. Now you need to turn left side body from the wall - shoulder and hip at 45 degrees. Gotta tense up latissimus the back, but not the shoulder. It is from this position that Alexander Popov takes a stroke.

The main thing is not to focus on the stroke, but on the rhythmic movement of the whole body.
Hands should walk in a straight line and be reasonably relaxed at all times, except for repulsion.

Total Immersion: к how to train

You need to reprogram your muscle memory if you are already swimming. Or create a new movement pattern if you are learning from scratch. This will require first of all meaningfulness, then gradual and regular training, in which your body and nervous system must master and remember the correct sequence of movements and the sensations associated with them.

One of the problems experienced swimmers have is the ingrained habit of improper technique. It is necessary to scrupulously work on each element. Technique first, then strength. Remember Popov's example: before defeating Biondi, Alexander and his coach analyzed the videos for a long time and worked on the technique, and not on the frequency and strength of the stroke. This is what allowed Popov to win in Barcelona and then remain the leader for many years.

Features of training

Let's pay attention to the technique of teaching tennis. You will not see newcomers who, under the guidance of a coach, go about randomly throwing the ball over the net. As a rule, training begins with the fact that the coach throws the ball to the student and he hits it, repeating the same movement. Thus, the correct movement pattern is formed. Further, the movements become more complicated. And only after working out and mastering all the basic movements, the actual game of tennis begins.

Swimming workouts often look like this: a student swims supposedly in a freestyle, and the coach comments on individual elements from the side. Most professional swimmers begin swimming at the age of 5-7 and find the right movements instinctively.

Is it possible to learn to swim on your own as an adult? Yes it is possible. Do you need to swim for hours / weeks / years for this, patiently waiting for quantity to turn into quality? No, it is not necessary, even harmful. An effective way is the consistent, conscious execution of exercises for swimming technique to develop motor skills.

Is there a limit to the perfection of technology? No, the work on the technique can go on all the time all your life.

How long does it take to master basic skills correct swimming? Hours of conscious work on technology. In workshops led by the author of the book, swimmers reduce the number of strokes from 21 to 16 (in a 25-meter pool) during one day of training.

How our body works

Important information about how the body works:
1. Muscle memory ... Your body remembers the movements and makes them automatic. To learn to swim effectively, you need to change your motor habits (if you are already swimming) or create a new one.
2. A large movement consists of small ... After practicing every little movement with simple exercises, you can accomplish great. Each movement continues into the next. Consistency and awareness of execution are important.
3. Only correct movements ... Instead of trying different angles and movements, by trial and error finding the right ones, you immediately float correctly.
4. Movement instead of thought ... You don't simulate swimming in your head and then try to bring it into the water. You exercise consistently and progress towards your goal.

Total Immersion: Approach to training

The Total Immersion method consists of a series of exercises to build and practice correct motor skills. In the practical part of the summari, the exercises are grouped into 6 lessons.

How to do the exercises most effectively?
1. When practicing the exercises, observe the following sequence:
-the first repetitions - think about the problem solved by this exercise;
-Next repetitions - watch how the exercise solves the problem;
-final repetitions - remember the right feeling.

2. Listen to your body constantly. It is this that should send a message to the brain that the exercise is being performed correctly. Typically, 10-15 minutes per exercise is sufficient.

3. Don't get tired. Your body and mind should be in good shape at all times you exercise. Maintain your concentration. Pause for 10-15 seconds between 25-meter sections. You should have a feeling that your technique is improving on every stretch. If it disappears, go back to the previous exercise.

4. Perform the stretches in full coordination. Alternate between a 10-15 minute exercise session and a test swim in full coordination. Each such swim should be better than the previous one. If you feel an improvement in any piece of technique, try strengthening it.

5. Exercise with fins as needed. In the "Full Immersion" technique, the legs do not need to do strength work, but during the exercises good job legs allows you to keep the body on the surface in correct position... Some beginner swimmers spend all their energy on working their legs and maintaining body position, but there is no strength left on the actual exercise. Put on short (speed) fins and focus on the exercise.

Think about the exercise you are currently doing. Moreover, concentrate on one element of the exercise.

To begin with, the ratio can be 4 to 1: four pools of exercises, one in full coordination. Then, perhaps, you will come to the conclusion that one pool of exercises will be enough for you to memorize.

The main thing is your feelings

One of critical aspects training - learning how to receive sensations and interpret them. As you swim, your body communicates all the details and deficiencies of your technique. Listen to it and gradually improve your technique. We are used to commanding the body what to do. Now it is important to learn how to perceive feedback. Exercise is the outer form. You consciously perform a certain sequence of movements for a while. And the sensations serve as a test - whether you are performing these movements correctly, naturally.

Your main enemy

The main enemy of a swimming person is water resistance. Sensations in the body that tell you about the right direction to work with it:

1. Reliance on chest ... At the same time, the thighs are close to the surface. The sensations can be different: that you are sliding downhill, that someone is pressing on your back from behind. In any case, there should be lightness in the legs, they should slide freely behind the body.

2. Weightless front arm... The outstretched arm should slide forward freely, without tension.

3. Strive forward with your hand, try to reach the edge of the pool... It is sometimes difficult for beginner swimmers to lower their hand into the water without making a stroke. Imagine this is your last stroke before the turn and you need to slide another meter or two to the side. Maintain this sensation with every stroke. The movement of your hand should not be abrupt - stretch forward smoothly and slowly.

4. Slightly delay changing hands... Do not start working with an outstretched hand until the other enters the water. As an exercise, try three different options- start the stroke with an outstretched hand when the second hand is: a) below the elbow of the first hand; b) above the elbow; c) at the level of the forehead. Record the number of strokes in each variation.

5. Turn your stomach to the side (to one and the other)... You won't be able to literally do this, but the feeling that for each stroke you turn your stomach to the side will allow you to focus on the correct movement of the body. The movement should go from the center of the body and end with a hand stroke. Intense rhythmic impulses to each side, with the whole body.

If you find it difficult to concentrate on the sensations, the following tips can help you:
- alternate work on the form and work on sensations on the same exercise;

Work in short intervals, you can try to swim for a while without inhaling - not to train holding your breath, but to focus on the sensations of movement;

Move as slowly and relaxed as possible;

After each segment, stop and analyze what you worked on, what you did, how you felt;

Perform the required number of repetitions to memorize the sensation (we recommend 8-10).

If you're already starting to get good at it, try the following mode:

Increase the segments up to 50-200 meters;

Try to track two sensations at the same time (for example, support on the chest and a weightless hand);

Trace two sensations sequentially within one segment (for example, the first 25 meters - support on the chest, the second 25 meters - a weightless hand);

Two speeds in one segment - swim the second 25 meters at a competitive speed. Were you able to maintain concentration without oiling your technique?
How many strokes do you need and how can you reduce the number of strokes? Alexander Popov in the competition did 33 strokes in a 50-meter pool. In training, he performed 24 strokes.

The training method is simple:

Popov did 24 strokes at a calm speed;

Then he gradually increased the speed until he began to do more strokes;

Reduce speed to maximum for 24 strokes and repeat.

Thus, with each workout, he pushed back his speed threshold, trying to "squeeze" the maximum out of each stroke.

First, you need to determine the starting point - your current number of strokes per your training pool... The speed of the test swim should not be maximum - imagine that you are swimming for a kilometer and this is a segment in the last hundred, you are already tired enough, your speed is far from sprint. Have you counted? Now, make a promise to yourself to cut that amount at any cost!

Let's say you did 22 strokes in a 25-meter pool. Your target is 20 strokes. What happens next? Then you easily and happily swim 200 (and maybe 500) meters, doing 20 strokes per pool. But then you get tired and on the next segment you see that 20 strokes are behind, and the side is still far away. It is at this point that speed, rivals, and other distractions take a back seat - you start working on your technique!

Target indicators:
1. First target - less than 20 strokes in a 25 meter pool.
2. Once it is easy, try doing less than 40 meters by 50 meters.
3. Then - less than 80 on a segment of 100 meters. (For comparison, a top-tier swimmer does 56 strokes per 100 meters.)
4. Sets of 8-10 approaches of 100 meters (less than 80 strokes) with pauses of 15-30 seconds.

Don't be cunning. If you kicked hard and swam without half-pool strokes, then your technique did not improve, you just kicked well!

Figures for reference, 100 meters in a 50 meter pool: average level- 80 strokes (2 times 40 strokes, time - 2 times 40 seconds), good level - 60 or a little more.

Total Immersion: Practice

One of the main benefits of Total Immersion training is a series of simple, step-by-step exercises that you can use to gradually master correct technique crawl swimming.

If you train on your own, then your best assistant is the Freestyle_disable Made Easy video:

(In this Youtube playlist, be sure to check out Shinji Takeuchi's fantastic swimming!)

Practice principles

1. Pure mind
Forget old muscle habits. Start swimming with a clean slate.

2. A complex movement consists of simple parts
Practice simple movements in sequence and then combine them into one large one.

3. Smooth breathing
Take the stopwatch away, focus on relaxed glide and technique. Watch your breathing and heart work. Between swims, Terry recommends doing breathing exercises from yoga.

4. Recovery
Pause and take 3 breaths between the segments. Inhale calmly, exhale slowly, relax your body before inhaling again. If you are doing long stretches, you can lengthen the pause and take 5-7 breaths.

Balance
In preparing this book, the author proceeded from the assumption that the reader has no skills and starts learning from scratch. Therefore, some of the exercises will seem very simple to those who already know how to swim. Don't be fooled - all exercises are essential to develop the right skills. Regardless of your level - start with the first exercise and do them all in sequence.

Lesson plan:
- 25 m exercise 1;
- pause 3-5 breaths;
- 50 m (25 right + 25 lev) Exercise 2, the first part on the side;
- pause 3-5 breaths;
- 25 m exercise 2, active balance.

Exercise 1
All newcomers are rowing desperately with their arms and legs. For the sole purpose of not drowning. Your first challenge is to feel that you won't drown if you stop paddling. The water itself will push you to the surface.

Staying in absolute Buddhist calm, in the supine position, arms along the body, slowly and relaxedly touch with straight legs. Your body should be stretched and relaxed at the same time.

Some beginner swimmers are better off doing this exercise in a shallow pool, where they can stop and stand 5-10 meters away. If you feel tired, stop, regain a relaxed and focused state, and continue calmly.

1. In the supine position, find the correct position of the head - water lightly on the forehead, at the edges of the glasses, at the chin. Take your time, it may take you 5 or 10 minutes. Then lower your chin slightly towards your chest.

2. Relax your shoulders. At the same time, the shoulders will "go" slightly forward, rounding the back.

3. "Push the float down." Keeping your head and arms relaxed, lower your upper body (your lungs, your bobber) a little deeper. Wait for your hips to pop up. They will come out to the surface on every thrust - this indicates that you have a good balance. Your feet shouldn't be picking up spray - just slight ripples.

4. Don't use your hands. Ideal balance - your arms along your body, you stay in the water without hands.

5. Swim less than 25 meters if necessary. Get some rest. Your state should always be calm and relaxed. As soon as you feel tensed or tired, pause.
Imagine yourself carrying a glass of champagne from side to side on your forehead.

Balance exercise is easier to do overweight people... Wiry swimmers (often triathletes) may need an assistant to create movement by pulling slightly on the shoulders or head. At this point, the swimmer needs to try to remember the sensation. The partner can accelerate, and then release, then pull again and again release, each time increasing the distance in time that the swimmer overcomes on his own. You can also use fins. Don't be discouraged if you have not been able to perfectly position your body in the water, balance will also be practiced in other exercises.

Exercise 2

You need to find your point of balance - the position of the body in which you perform the exercises. This is the so-called "side balance", but in fact, the position of the body is individual and depends on the build of the swimmer. For example, for a wiry person, this position will be close to the supine position.

1. Starting position on your back, arms along the body, calmly move forward at the expense of your legs. Find balance and swim.

2. Slowly turn your body to the side so that your shoulder and arm (along your body, palm on your hip) are above the water. Head in place, look up. Find a position of the body on your side that is comfortable for you. If you are uncomfortable, return to the original state and slowly try again.

3. Check your position: water around your head (forehead, edge of glasses, chin), head not thrown back, back round. You can look for a relaxed state by helping to maintain balance with your lower arm.

4. Concentrate on the fact that your body is both relaxed and extended. Inwardly, you must remain as calm as possible.

5. Repeat on the other side. As a rule, the position is better on one side. Work to maintain balance and a calm, relaxed state as you move on both sides. Do one pool on one side, pause for a minute, and repeat on the other side.

6. After you have mastered the movement on each side, start exercising active balance by changing sides. Take a position on one side, take 3 breaths, then turn to the other. Important: relaxation, calmness, even breathing, arms along the body, head in one position, legs do not raise splashes.

A common mistake is to bend your knee to 90 degrees (like on a bicycle). The effective swimming angle is 30 degrees. How to fix:

Exercise "float". In an upright position in the water (as synchronized swimmers), arms crosswise on the chest. Move your legs relatively straight, keeping your body straight, head above the water. Legs should be relaxed, long and flexible. 15 seconds exercise, 15 rest.

-"Tow". When your partner accelerates, you don't need to swing your legs hysterically and you can concentrate on slow and relaxed work from your hips to your toes.

- "Balance on the side". In the lateral position, gravity works perpendicular to your leg movements, so you're less likely to bend your knee 90 degrees.

Stretching. As we age, the ankles lose their elasticity (jogging also contributes to this). Stretching will help you regain your shape.

Weightlessness and glide

You need to stretch as much as possible to give your body correct shape... In this case, you need to ensure that there is no tension in the body.
If at some point you tensed, began to drown, stop, take a few relaxed breaths in and out and repeat the balance exercise.

Lesson plan:
-50 m exercise 3 (25 meters on each side)
-50 m exercise 4 (25 + 25)

Pause and catch your breath between swims.

Exercise # 3

As you remember from the theoretical part, it is necessary to lengthen our body as much as possible along the "waterline".

1. Starting position - on the back, arms along the body, legs give light acceleration. You should feel relaxed and supported by the water. Check again the position of the body, head, legs (there should be no splashes). Now slowly turn the body to the side so that the entire hand from shoulder to toes is above the water, face is looking up. Continue in a relaxed movement.

2. Gently move your lower arm to an extended overhead position. The palm can be turned to either side, the hand should be relaxed. Keep driving.

3.Now extend the body and arm slightly. You need to stretch as much as possible, but without unnecessary tension in the arm and body, the back of the head close to the shoulder of the outstretched arm. Still without tension, check the posture: head on the center line (axis) of the body, water evenly around the face (chin, glasses, forehead), upper arm along the body above water, lower arm extended, fingers 2–5 cm below the surface of the water.

4. Slide in this position. Train on both sides until you are satisfied with sliding on the "weak" side.

As you practice the exercise, focus on the line from the fingers of the outstretched arm to the toes and maximum relaxation. Take sufficient pauses with breathing exercises.

Exercise 4

In this exercise, an extremely important skill is practiced - to rotate the body to inhale, and not to twist the head.

1. Starting position - on the back, arms along the body, gentle forward movement at the expense of the legs. Turn gently to the side and extend your lower arm, as in the previous exercise. Check the posture: the body is stretched and relaxed.

2. Slide in this position for a while. Next, gently turn your head down into the water and slightly turn the body behind it. Now your position is on your side (previously you were lying slightly on your back, now slightly on your stomach), gaze at the floor, your lower arm is extended, the upper one is pressed to the body. Continue in a relaxed movement for a while.

3. Preventing you from running out of air, gently roll to the starting position face up.

4. You should return to your original balanced body position. Don't be discouraged if it didn't work the first time. Continue face-up movement, regain breathing (minimum 3 breaths) and relaxation. Repeat the roll.

Secrets of the second lesson:
-when performing a roll, slightly press your head to the shoulder of an outstretched hand;
- in the face down position, the chest should be slightly drowned in the water, the feeling is as if you are flying down the hill with a superman head first;
- the face down position is the fastest; strengthen it, trying to mentally slip into the eye of the needle.

Turn underwater

The most important lesson. Practice each exercise until you feel confident. Only then combine them in a series. (If necessary, return to practicing the exercises.) The estimated time to complete the lesson is several hours.

Lesson plan:
Every workout starts with doing warm-up exercises 2, 3 and 4 for 10 minutes or more.

Series 200 meters:
-50 m (25 right + 25 lev) Exercise 2 (balance point);
-50 m (25 + 25) Exercise 3 (face up);
-50 m (25 + 25) Exercise 4 (face down);
-50 m (25 + 25) exercise 5 (look at the palm).

Series 100 meters:



-25m Exercise 6 on the other side.

Series 150 meters:
-50 m (25 + 25) Exercise 4;
-50 m exercise 6;
-50 m (25 + 25) Exercise 7;

Series of 150 meters (option 2):
-25 m exercise 4 on one side (face down);
-25 m exercise 6 on one side;
-25m Exercise 7 on one side;
-25m Exercise 4 on the other side (face down);
-25m Exercise 6 on the other side;
-25m Exercise 7 on one side.
It should take you several hours to practice the exercises and series of Lesson 3. Pause and breathe after every 25 meters. Within one exercise, also keep a relaxed state and take 3-5 breaths between cycles in the upward position.
Exercise # 5

1. Consistently relaxed, take the worked out poses: on the back - arms along the body, on the side - arms along the body, on the side - the lower arm is extended. Check the balance of each position. Move to each next position when you feel a confident, relaxed slide in the previous one.

2. Continue driving. Turn your head to face down. As you continue to move, check your body position. You should slide easily, like a slide, head first.

3. If necessary, turn over face up, restore breathing. Return to face down position. Pull up gently upper arm to the face, bending it at the elbow. The palm should go past the belly and chest. The final position is an open palm directly in front of the face. The shoulder, elbow, hand, and fingers are relaxed.

4. Make sure your shoulders are one over the other and your body is relaxed. (Be careful not to turn your stomach down!) Return to the starting position face up. Recover breathing and repeat. The estimated number of completed exercise cycles is 3 in a 25-meter pool.

Exercise 6
Turn underwater

1. Starting position - the palm moves to the face (as in Exercise 5). Continue moving your hand forward behind your head.

2. Simultaneously with the forward movement of the arm, make a smooth roll to the other side. In this case, the hand should stretch forward, and the second smoothly along an identical trajectory move to the thigh.

3. At the end point of the pivot, you should take a face-up position on the other side, lower arm extended, upper along the body. Check your body position - relaxed glide. And repeat a smooth roll with a change of hands in the opposite direction.

Secrets:
- the outstretched hand begins to go to the hip after the second hand "passes" by the face;
-the end point of the movement is after passing the balance point;
-the method of "inhaling with the navel" - when you see the returning hand in front of you, give the command to the body to turn in order to inhale "through the navel";
-the whole body works as a whole;
-At every moment of time, keep an extended position and continue sliding;
- movements are economical and collected, without splashes and large amplitude;
- the moment you see a returning hand, stop working with your legs, resume after taking a face up position.

Exercise 7
Double turn underwater

1. Starting position, as in Exercise 6. Roll to the other side, but do not lift your face out of the water. End point: You change your hand and slide on your other hand face down on your side.

2. In this position, check the position. And do the reverse roll. The final point is a face up position with an outstretched arm.

3. Continue to slide and recover your breath. Walk 25 meters on one side, then on the other.
Before working off next exercise pay attention to footwork. Stop kicking the moment you change hands - as soon as the first hand has passed your face. Resume when the second hand is back. Feel yourself floating by the momentum created by twisting your body when you change hands.

Exercise # 8
Triple turn underwater

1. Add to the previous exercise another cycle in the position of the face in the water.
2. Pay attention to the position of the body: in the final phase of each shift, one arm is extended forward, the other along the body backward.
3. Take small pauses in the final phase of each hand change in order to feel the slide. Look for a relaxed balance in this position.
4. Twist gently into the water, extending your hand on each shift.
5. After completing the 3rd step, remove the artificial pauses in the final phase. Add speed by reducing the swing a little.

Lessons 4 through 6 can be found in the full version of the book. Swimming does not end with the Lessons. You can endlessly improve your swimming technique. Videos on Youtube and regular referrals to summari and the book "Full Immersion" will help you with this.

Conclusion

Swimmer and coach Don Walsh began training on the "Full Immersion" system already in mature age... At the age of 50, he took part in the marathon around Manhattan Island in the United States. He made 26 thousand strokes in 9 hours. But you will be surprised to learn that his closest pursuers have done 14,000 more strokes! After the finish, he was in such a great mood that he was ready to make another lap, and his rivals barely moved their legs from pain throughout their body.

Terry Laughlin used to swim as a child, played for college. But by the age of 37, he gradually turned into a flabby father of the family, with shortness of breath and overweight... Once he awkwardly reached for bags from the supermarket and as a result spent 3 days in bed, barely able to straighten up. After this incident, he made a firm decision to return to training. A year later, he already covered a distance of 3000 meters, after 3 years he swam 5000 meters and competed in the Masters series.

Studying the "Full Immersion" method is a path of mastery that will allow you not only to learn how to feel free and easy in the water, but also to show new facets of communication with own body and consciousness.

This is the path of meditation on which many discoveries await you. The major upheaval will occur when you catch the flow state during your practice. "Full immersion" is not only a technique, it is a training philosophy. Once you enter the state of flow, you will enjoy the process itself, enjoy every moment, and you will be able to keep moving indefinitely.

Basic training principles:
Ease

Glide relaxed in the water and enjoy every stroke.

Efficiency
Your every movement works as efficiently as possible to move your body forward.

Harmony
Relaxing gliding in the water is akin to meditation or tai chi. You combine your inner calmness and light rhythmic body movements.

Way
The training process is a progressive, creative movement from simple skills to complex combinations, a constant search for harmony and balance.
