roundabout technique, a combination of movements

roundabout technique is a combination of movements
initial rotation and final movements of the launcher system
linear in the direction of the launch issue.
The goal of the first phase is to create an initial optimal speed and turn
the maximum release rate in the final phase of double support
.
The movement is the key transition from
rotary motion to linear motion. During the rotation phase (double
support left foot, phase of flight support on the right foot),
the location of the launch is in the form of a ring.
The body of the pitcher acts as a component of a large
centripetal force.
This force increases even if the center of mass oscillation
of the right foot is very far from the axis of rotation pitcher
. But these large centripetal forces
create a problem of stability, symmetry and direction
launch.
This difficulty given by the oscillation of the foot outward
creates balance problems and further penalizes
the centrality of the masses and the forces of the subject.
The strong support of the right foot with a not too
cushioning the knee in the middle of the circle
launch is the most important factor in the efficient transfer of
speed from the rotational movement to linear movement
launch. After the cushioning the pin is followed by
push with his right foot and the weight transfer system
pitcher on the front of the left leg, at this stage can occur
two negative aspects that may affect the good
successful launch: one is that of a excessive rotation
right side of the body mainly due to a blockage of his left leg early
which stops the rotation of the left side of the body and shoulders
, the other is an almost natural consequence
a decrease in the angular velocity of the hips
which can prevent a dynamic rotation of the right foot and knee
right axis of rotation forward and up.
The final action of the rotation is terminated after the rotation of the hips and shoulders
is over the speed is 6.10m / s.
After the right arm took part in the action of
issue by extending the elbow and shoulder the weight
speed increases up to 6.80 m / s up to the time of issue of
'tool to speed 13 m / s.
We can conclude that the release rate is more
report by the explosive power of the upper torso
. The high rate of release is related to the technique of action
release with the following major factors :
elbow height, involvement of the flexor muscles of the fingers
action release and locking of his left arm which
prevents rotation during the time of issue.

Italian Indoor Championships Youth

Saturday there were the Italian Youth Indoor Championships in Ancona, and note the not exactly positive performance of the newly promised in Loyal Francis shot put a little 'due to a lack of specific preparation for this event and some even abstinence from all competition. What
allienta there is, apart from the talent which I consider the future in the shot put Manucci Eugene in Italy, the others are within his reach. Too bad that do not record other Sardinians in the throws a bit to technical decisions as to the 'pupil Luca Collu (late for training) and Alessio Massa stopped for a slight injury

THE TECHNIQUE OF GIAVELLOTTTO

THE TECHNIQUE OF JAVELIN THROW

In all throwing athletes, the ultimate goal for achieve effective is to launch a
maximum path length of the acceleration, with the aim of achieving
maximum output rate of the tool. There are many technical factors that will contribute
for obtaining a good launch, among these can be identified:
- a speed-run optimal positioning of the body and the right tool in the pre the final launch
- exact positioning of the body masses and respect the chain
biokinetics in the final launch
- a right angle tool on the issue
efforts to achieve the above must be simultaneously put in place the following technical launch, which would simplify the mirror later.

TECHNICAL ANALYSIS OF THE STAGES OF LAUNCH

Bearing in mind that the launch is always considered as a whole, we can break the run into two main phases: a phase of initial acceleration
that cYcLIcAL, and a phase transition ACYCLIC that stage, the latter phase preparatory to actual launch

FASE CICLICA

L obbiettivo di questa fase è il raggiungimento di una velocità ottimale di rincorsa che consenta un’ulteriore accelerazione nella successiva fase
La velocità di rincorsa è una variabile soggettiva che si determina in relazione alle tendenze individuali di impostazione del lancio e alle caratteristiche fisiche dell’atleta . Superare o mantenersi al disotto della velocità ottimale significa compromettere l'efficacia del lancio.
Il livello prestativo è rapportato , oltre alla velocità ottimale di rincorsa , anche alla distanza entro quale tale velocità si estrinseca : Bauersfeld \ Schroter 1980 e Terauds 1985 sostengono che tale distanza ( fase cyclic) must be between 8 and 14 steps to run. We can summarize the peculiarities of this phase: *
length of the cyclical subjective, 8 - 14 steps *
run very rhythmic, remaining the most decontratti
* the transition to the next stage is to enable an increase in speed, and must be performed in smoothly

ACYCLIC PHASE

The purpose of this step is achieving the optimal biomechanical conditions that contribute to obtaining the right muscle and accurate claims tool setting angles of acyclic
During the athlete will run 4 or 6 steps and then 5 or 7 bearings, very important is the rhythm that will allow the gradual acceleration of the final.
In the preparatory steps are being analyzed, "acyclic" in the run-up to the exclusion of the last, which because of its peculiarities will be discussed in more analytical. We can thus summarize the most important aspects of this phase: *
acyclic at the start, when the tool on the support of the left foot is put aside or "pulled", the arm and the javelin are aligned with the axis of the shoulders , this movement must be accomplished in an extremely fluid. *
the tip of the spear will chin height, never above the eye height legs will
* to anticipate the bust, a key condition for creating the appropriate claims muscle in the final stage, the position behind the torso is not due to his actual decline (a factor which if achieved would be to subtract the entry speed), but by a ' Quick action leg that will "surpass" the upper body.
an extremely important at this stage is the transition from third to fourth arm (left - right for a right handed pitcher that uses the rate to five supports)

STEP PULSE

whose characteristics are: *
strong push in forward, sliding
* legs well in advance on the bust
* Left leg over your right leg in the air, to minimize the next phase of mono support
* the length of the step pulse is related to the physical characteristics of the athlete, but it is the longer wheelbase of the javelin run-up to
As regards the speed reached during the run-acyclic, there is always a speed change that tends to fall closer to launch (because of the step pulse), however I always got a good performance when it is limited as possible.

FINAL LAUNCH

This phase is very sensitive to the success of the launch, is the moment when all the forces accumulated have to move the axis of the tool with the end result to obtain the maximum output rate and the exact departure angle. We can subdivide this phase into two main parts: *
PREPARATORY PHASE OR MONOAPPOGGIO
* LAUNCH - DOUBLE SUPPORT AND RELEASE TOOL

PREPARATORY OR MONOAPPOGGIO

At this stage it has reached the optimum position and biomechanical favorable conditions for the next issue of 'tool
In theory the end of this phase, the pitcher should take the following positions: *
right foot forwards at an angle of 45 ° to the direction of the launch
* arm stretched out behind casting of course, to the shoulder and hand supinated
* axis of the javelin and shoulders parallel
* leg should strive for maximum leg extension and muscle tension before they hit the ground the angle of the tool
* from the horizontal must be between 30 ° -35 °. *
the angle of loading at the knee of the leg support in swing between 140 ° to 160 °

launch phase - DOUBLE SUPPORT AND RELEASE TOOL

is at this stage where we have the maximum output rate of 'and accurate positioning of the tool to achieve the correct angle output
analyzing this stage we can highlight some of the positions or "moments" that are peculiar to the specialties of the support leg prop: *
the leg is extended and high tension, with an angle of about 45 ° to the horizontal axis of the shoulders
* is still aligned with the javelin
* flipping arm lying supine and with his hand to the shoulder, completely relaxed and inactive. *
right leg pushes your hips to the leg position at ARCO, or maximum tension: *
frontalizzazione beginning of the shoulder that begins with a strong rotation in the direction of the Director of the launch of the foot, knee, hips and shoulders
* the left side of the shore, stops the rotation of the shoulder staring at the front of the arm *
flipping back and is still lying idle release of the tool: • early intervention
pitching arm, whips, which intervenes with the advance of the elbow, passing through high near the head, and then the forearm and hand: The operation of the arm must be added last and should not anticipate an earlier stage
* left leg is extended, and high tension in the basin so that no has the opportunity to look back
* remains as much as possible toward the direction of the javelin throw
* will be addressed with the right angles to the direction of launch

recovery phase

In this phase the athlete, when you release the tool, must recover the stability to avoid a draw on the platform. To best achieve this important phase, the athlete will perform the launch, the support leg of the shore, with a distance from the end of the platform about 1.5 m -2 depending on the individual, this is used for positioning the right foot that will allow the athlete to slow down after the launch. Even at this stage, the athlete will be looking toward the direction of launch.
