Novice level flawed Breaststroke Technique

Novice level flawed Breaststroke Technique
  • freestyle is the fastest swimming style.
    • Trudgen (also known as trudgeon): The trudgen is similar to the freestyle, except that it is swum with a scissor kick
    • Trudgen crawl: Similar to the trudgen, but with the use of the a flutter kick between the scissor kicks
    • Double trudgen: Similar to the trudgen, but the sides of the scissor kick alternate
    • Double trudgen crawl: Similar to the double trudgen, but with a flutter kick between the scissor kick alternate
    • Dolphin crawl: Similar to freestyle, but with a dolphin kick. One kick per arm or two kicks per cycle. This style is often used in training.
    • Catch up stroke: A variation of the front crawl where one arm always rests at the front while the other arm performs one cycle.
    • Total Immersion is a version of freestyle in which body rotation is emphasized to increase the propulsive effect of the arms.
  • Butterfly
  • Breaststroke
  • Heads-Up Breaststroke: Similar to the breaststroke, but the head stays out of the water. This style is very popular for recreational swimmers and also for rescue swimmers approaching a victim.
  • Slow butterfly (also known as moth stroke): Similar to butterfly, but with an extended gliding phase, Breathing during the pull/push phase, return head into water during recovery. This style uses two kicks per cycle.
  • Dog paddle: face over water and paddling with alternate hands, often with the nose and mouth above the water. This stroke can be used in reverse to propel the body feet first.
  • Human stroke: Similar to the dog paddle, but the arms reach out more and pull farther down.
  • Survival travel stroke: Alternating underwater arm stroke, one cycle for propulsion, one for lift to stay on the surface. This style is slow but sustainable.
  • Breast feet first strokes:With legs extended, use the arms with a pushing, flapping, clapping or uplifting motion.
  • Snorkeling: Swimming on the breast using a snorkel, usually in combination with masks and fins. Any stroke on the breast can be used, and there is no need to lift or turn the head for breathing.
  • Finswimming is the progression of a swimmer using fins either on the water surface or under water. Finswimming is usually done on the breast.
  • An arm and a leg : is the progression of a swimmer clasping one leg with the opposite arm, and using breaststroke movements with the remaining arm and leg.

Back

A depicts elementary backstroke;
B depicts backstroke.
Both arms move synchronized with a small synchronized kick. This is also sometimes known as the Lifesaving Kick
  • Inverted breaststroke
Similar to elementary backstroke, but with a breaststroke kick.
  • Inverted butterfly
Similar to elementary backstroke, but with a dolphin kick. This is often used for training.
  • Back double trudgen
Similar to the backstroke, but with a scissor kick to alternating sides.
  • Flutter back finning
Symmetrically underwater arm recovery with flutter kick.
  • Feet first swimming
A very slow stroke on the back where a breaststroke movement with the arms propels the body forward feet first. Also the arms can be lifted out of the water and pulled backwards together with a scooping movement. Alternatively, the arms can be raised behind the head, alternately or together pushing with the hands, propelling the body. Similarly, the hands can be brought together in a clapping action. These strokes are often used for training.
  • Oarstroke
The newest form of stroke created in 2008 by novice water polo player Daniel Edwards. This stroke relies on powerful upper body strength as you have to throw your both your arms behind you simultaneously and bring them down into the water again in a tilted windmill motion, while at the same time shoving the water behind you. While moving your arms your legs are constantly breaststroke kicking.

Side

Lying on the side with alternating underwater recovery and a scissor kick
  • Overarm sidestroke
Similar to the side stroke, but with an over water recovery of the top arm. Used mostly for training purposes to help with freestyle.

Miscellanea

  • Corkscrew swimming
Alternating between front crawl and backstroke every arm. This leads to a constant rotation of the swimmer. The stroke is used mainly for training purposes and is also sometimes known as Newfie Stroke, referring to Newfoundland. When rotating every 3rd stroke, this is called waltz crawl.
  • Underwater swimming
any style with underwater recovery can be swum under water for certain distances depending on the need for air. Underwater swimming on the back has the additional problem of water entering the nose. To avoid this, the swimmer can breathe out through the nose or wear a nose clip. Some swimmers can close their nostrils with the upper lip.
  • Gliding
The swimmer is stretched with the arms to the front, the head between the arms and the feet to the back. This streamlined shape minimizes resistance and allows the swimmer to glide, for example after a start, a push off from a wall, or to rest between strokes.
  • Turtle stroke
on the breast, extend right arm then pull, after pushing with the left leg (while opposite limbs are recovering), then opposite limbs repeat this process, i.e. left arm pulls after right leg pushes. Uses muscles of the waist. Head can easily be above or below water: this is a slow but very sustainable stroke, popular with turtles and newts.

Special purpose styles

A number of strokes are only used for special purposes, e.g. to manipulate an object (a swimmer in distress, a ball), or just to stay afloat.

Manipulating objects

  • Lifesaving stroke: Similar to the side stroke, but only the bottom arm moves while the top arm tows a swimmer in distress
  • Lifesaving approach stroke (also known as head-up front crawl): Similar to the front crawl, but with the eyes to the front above the water level, such as to observe the surroundings as for example a swimmer in distress or a ball
  • Water polo stroke: This stroke is used for water polo and is similar to front crawl, but with head above the water and a slightly inward curved arm to keep the ball between the arms and in front of the head.
  • Pushing rescue stroke: This stroke helps assisting a tired swimmer: The tired swimmer lies on the back and the rescuer swims a breaststroke kick and pushes against the soles of the tired swimmer (not taught or recognised by the RLSS body governing Uk lifeguarding)
  • Pulling rescue stroke: This stroke helps assisting a swimmer in distress. The both swimmers lie on the back, and the rescuer grabs the armpits of the swimmer in distress and performs a breaststroke kick (on the back) for forward motion. The kick has to be not too shallow as otherwise the victim will be hit
  • Extended Arm Tow(unconscious victim): swimming sidestroke or breaststroke on their back the rescuer holds the head with a straight arm the hand cupping underneath the chin, and ensures that the mouth and nose are out of the water
  • Arm Tow the rescuer swims sidestroke, behind the casualty holds the upper right arm of a casualty with their left hand or vice versa lifting the casualty out of the water
  • Vice Grip Turn and Trawl - used on a casualty with a suspected spinal injury: The lifeguard approaches slowly to the casualty (who is usually face down in water), places one hand on the casualty's chin, with arm pressed firmly against the casualty's chest. The other hand is placed on the back of the casualty's head with the arm down the casualty's back. Both arms press together (like a vice), and the lifeguard uses his feet to begin moving forward and then rolls under the casualty to come up alongside her but with the casualty not on her back. (This is one of the hardest lifesaving maneuvers, as the grip must be perfect on the first attempt; otherwise the casualty may be given further spinal damage, such as as paralysis.)
  • Clothes swimming: The swimmer is wearing clothes that restrict movement when wet, i.e. almost all clothes. This is done to practice situations were the swimmer fell in the water dressed or the rescuer did not have time to undress. Due to the restricted movement and the weight of the wet clothes over water (weightless under water!) an overarm recovery is not possible. Most swimmers swim breaststroke, but any stroke with underwater recovery is feasible.
  • Rescue tube swimming: The lifeguard pulls a flotation device, which is pushed forward when approaching the victim.

Without forward motion

  • Survival floating (also known as dead man float): Lying on the prone (face down in water) with minimal leg movement, and staying afloat with the natural buoyancy. Lift the head to breathe only then back to floating. This style is only to stay afloat and to rest.
  • Back floating: Similar to the survival floating, except on the back.
  • Treading water: The swimmer is in the water head up and feet down. Different kicks and hand movements to stay afloat. This is useful to keep the head out of the water for a better view or to catch an object as for example in water polo.
  • Sculling: This is a figure 8 movement of the hands for forward motion or upward lift. Used in surf lifesaving, water polo, synchronized swimming and treading water.

Swimming Better To Do List - 10 Better Swimming Tips for Swimmers

There are many things that swimmers can do to swim better. This to do list of 10 ways to better swimming could help any swimmer improve their swimming. Get this to do list done and swim on!

1. Do swim frequently

If you don't average about three swims a week you will lose your feel for the water and your technique will begin to deteriorate. No feel, no technique, no speed. If the option is between one or two long workouts or three or four shorter workouts, swimmers seem to do better when they swim more frequently as opposed to only doing a few longer workouts each week.

2. Do swim with good technique

Maintain the best possible technique at all speeds during a workout. If you try to go fast with bad technique, you are wasting energy. If you can teach yourself to go fast while using good technique, you will make bigger gains.

3. Do drills as part of every swimming workout

Early in your workout, in the middle of your workout, or at the end of your workout (or any combination of the three!) do some specific technique work to reinforce good swimming skills. There are many drills you can do to stay tuned up, or to help you develop better technique.

4. Do challenging workouts

One or two times a week (depending upon how frequently you swim) do part of your workout with oomph - push the effort, go hard, whatever you want to call it. If all of your workouts are focused on technique, your technique will improve. But what will happen when you try to go faster? You will get tired, your technique will deteriorate, and you might as well call it a day. If you are doing some hard or challenging workouts - mixed in with technique work - as different workouts or as part of the same workout - you will learn how to hold good technique while going faster.

5.Do easy workouts

Depending upon your swimming goals, there may be no reason to do more than one or two tough workout sets a week, as long as you do one or two easier workouts, too. Work hard on the hard things, and easy on the easy things, and each kind of work will give better results.

6. Do streamlines

It might be a start, a push-off, or a turn, but you should always do things the same way - streamline, then into the transition between the streamline and swimming. But first, always a streamline.

7. Do leave the wall the same way every time

Always push off the walls the way you would if you were coming out of a turn. When you starting a set, you should push off the wall exactly the same way that you would be pushing off the wall if you were coming out of a turn. Most races have more turns than starts, and getting some extra practice with any part of a turn is a bonus.

8. Do wear a swimsuit made for competitive swimming

This doesn't mean spend $300 on the latest and greatest high-tech slicker than skin piece of swim wear. It means don't wear baggy beach shorts if you are trying to improve your technique or go learn how to hold technique when going faster. There are times to wear a swimsuit that gives you some extra drag, but not before you have mastered good technique.

9. Do ask someone to watch you swim

Better yet, get someone to video you. Getting some eyes to watch what you do (or using your own via a video review) while you are moving through the pool can yield some great feedback on your swimming technique that you may have not realized.

10. Do use flippers occasionally

Among other benefits, swim fins or flippers can help you achieve (artificially) a better body position and you will learn what that position feels like while moving. Then, when the flippers are off, you can try to recreate that position by feel, since you will already have a better idea what it will feel like when you get there.

What's Good About Swimming

some of the health benefits of swimming

By Mat Luebbers, About.com

Swimming is good exercise (that's obvious). Swimming is a lifetime sport that benefits the body and the whole person! But what is it that makes swimming good, specifically? That depends on what you are trying to accomplish.

Swimming is a healthy activity that can be continued for a lifetime - and the health benefits swimming offers for a lifetime are worth the effort it takes to get to the pool.

Why do you swim? For the health benefits to your heart and lungs? For the chance to be with some of your friends at the pool? Because, in your case, running everyday hurts? Because you like the feeling of floating and sliding through the water? Or is it something else?If you are looking for a break from the heat of the summer, then a dip in the water is exactly what you need; swimming is a way for you to cool off. It fills a wonderful recreational need for individuals and families, from beach and pool fun to water parks.

Maybe you are a runner, training on a regular basis, and want to find an activity that keeps your heart rate up but takes some of the impact stress off of your body. Perhaps you have been doing some other form of land exercise, and now an injury prevents you from putting weight on a knee or ankle. Swimming can help you. Kicking workouts, water aerobics, pool running, or a regular swimming workout can all give you a great exercise session without the weight of your body pounding you with each move.

Regular swimming builds endurance, muscle strength and cardio-vascular fitness. It can serve as a cross-training element to your regular workouts. Before a land workout, you can use the pool for a warm-up session. Swimming with increasing effort to gradually increase your heart rate and stimulate your muscle activity is easily accomplished in the water. After a land workout, swimming a few laps can help you cool-down, move blood through your muscles to help them recover, and help you relax as you glide through the water.

Swimming does burn calories at a rate of about 3 calories a mile per pound of bodyweight. If you weigh 150 lbs. and it takes you 30 minutes to swim one mile (1,760 yards or 1,609 meters), then you will be using about 900 calories in one hour. However, many swimmers do not swim that quickly, and many cannot swim for that distance or duration.

Spending time in a group workout, whether water aerobics or a master's swim practice, is a great social outlet. Exchanging stories, challenging each other, and sharing in the hard work make swimming with others a rewarding experience.

There are other psychological benefit to swimming, if you allow it to occur. Relax and swim with a very low effort. Let your mind wander, focusing on nothing but the rhythm of your stroke. This form of meditation can help you gain a feeling of well-being, leaving your water session refreshed and ready to go on with the rest of your day. Many swimmers find an in-direct benefit form swimming. They develop life skills such as sportsmanship, time-management, self-discipline, goal-setting, and an increased sense of self-worth through their participation in the sport. Swimmers seem to do better in school, in general terms, than non-swimmers as a group.

One thing swimming is not good for is losing a lot of weight. The on-line Merck Manual explains that swimming is not the best way to lose weight due to the cooling effects of being in the water. While you do use a lot of calories swimming, once you get out of the pool much of that calorie burning stops. Doing land based exercise like running or cycling may use about the same amount of calorie per hour as swimming, but once you stop exercising the land-based workout usually leads to continued increase in calorie use for as long as 18 hours after the workout. Why? Because when you are in the pool you don't heat up as much as you do on land, and your body does not have to work to cool you down as much once the exercise session concludes. Swimming does exercise almost the entire body - heart, lungs, and muscles - with very little joint strain. It is great for general fitness, just not a great way to drop excess pounds.
