interesting report that I share with you, our friends ...... greetings tritim
all know that swimming is the technical discipline triathlon and the perfection of it has benefits very important (higher speed, less risk of injury, etc..). The technical improvement of motor learning is to be based on three fundamental points (TOP):
Observation Theory -------> -------> Practice
THEORY
need to gather all available material to study the route of arms and legs, body position and head, etc.. For this you can use literature, videos web sites, graphics, etc.La theory remain etched in your mind and help you to identify buggy.
NOTE
On the Internet there are many videos and animations on front crawl technique that allow you to better understand the concepts teóricos.Para this, and before reading the theory I recommend you visit and download version sr free software. smooth. ( http://www.swimsmooth.com/ )
Mr Smooth is a lively software (PC and Mac) that lets you see the crawl technique in great detail and from 7 perspectives.
Another "Pro" version with additional facilities at a price of u $ s 35 for individuals and u $ s 175 for commercial use ..
can also help a lot to ask your coach film you periodically to see those errors in the water notes.
PRACTICE
There are many exercises and drills to train the technique that we will see in subsequent post. To them it is important to remember these concepts:
-The technique works at low intensity so that your mind can begin to acquire the concepts and your body can coordinate. Be patient and consistent in order to improve every aspect.
"Do not try to train many aspects at once. Concentrate on one aspect such as the entrance of the hand in the water and the only limit yourself until you feel that you have acquired the concept. It then goes to another and so on.
-Incorporates technical exercises for all your training (preferably at the beginning of the session) and try to change them to not get bored. Changing a habit is never easy and it is important not to get discouraged and then you will see the results.
-Make your exercises to improve joint mobility of the shoulders and ankles and do not let mainly to train the flexibility of your muscles as more flexibility, greater efficiency of the gesture.
LOS BRAZOS EN EL CROL
La brazada en el estilo libre tiene dos partes
1º- Tracción o parte acuatica: compuesta por 4 fases (Entrada, Extensión, Agarre, Tirón y Empuje)
2º- Recobro o parte aerea
TRACCIÓN O FASE ACUÁTICA
1-Entrada de la mano :Antiguamente se enseñaba a los nadadores a realizar la entrada con rotación interna del hombro diciendoles que lo primero que debía entrar al agua era el dedo gordo. Esto es incorrecto y puede provocar lesiones en el hombro.
The correct entry is made for the shoulder in neutral position and the hand entering the first finger aligned with the shoulder without ever crossing the line of travel. The arm is in semi-flexed, with the elbow in a position higher than that of the hand facing up, not the wall.
water entering the palm should be facing down and slightly away from your body. At this time the other arm must be about halfway to the water phase or propulsion.
The more ahead of our body to the entry better. For this it is important to display the phrase "search by hand."
2-extension of the arm.
Many times, trying to stretch too committed erorr input as your wrist and elbow are below the fingers generating an undesirable braking effect (hand up).
The movement is mostly slightly forward and outward with a progressive extension of the arm. It is recommended that the fingers are always slightly below the wrist with a small bending of the latter. The elbow should remain higher than orientadose hand up and out. The extension coincides with the onset of body rotation.
3-Hold
The hand and forearm should look deep down and looking back while the left elbow and forearm near the water surface.
elbow flexed gradually increasing its speed as it deepens its hand position. The maximum elbow flexion then coincide with the maximum depth of the hand. 
The body rotates to allow pectoral and dorsal muscles do most of the work and absorb deltoides relatively low. Show
are trying to grab a barrel.
If exaggerated arm extension (phase 2) begins to grip your arm without bending and thrust of water causes a downward instead of backward unbalanced the body without favoring progress. Furthermore, this error in the technical gesture overload the rotator cuff and to continue and causes a very painful injury.
4-Haul
The hand must remain concave fingers together across the recorrido.El elbow begins to bend outward and going forward until the arm and forearm are a L. Once the hand, elbow and shoulder are in the same plane the hand is directed inward and backward with the elbow out. The movement continues to accelerate gradually.
When the hand reaches the lowest point of travel (dejajo head) begins adentro.En sweep this point the elbow is pointing directly to the wall while the arm goes hand in, back and up using mainly the deltoids (shoulders) and triceps. 5-Push
This is the phase of maximum propulsion stroke.
When you start this stage the opposite arm that pushes the water enters the hand describes a way similar to S while pushing speeds inward and backward from the chest to the waist.
under water movement is from lower to higher. The hand should be accelerating as it goes through phases, however, care must be taken with the emphasis on the push as too much of it can cause the swimmer at the end of the trail ends pushing the water up hurting your position. AERIAL RECOVERY OR PART
hand after the push phase out of the water edge, ie with the palm facing the thigh without pushing the water upward.
occurs at this stage the return of the hand from the rearmost point of the point immediately preceding the new entry into the water.
First out of the water is the elbow that moves upward and forward to achieve its maximum height when the hand passes through the armpit.
hand and wrist are relaxed. When the elbow reaches its highest point, the arm begins to extend forward and the hand goes to his new entry into the water. A good lift of the elbow provides more advanced input. Summary of phases
